I argue that we can make use of Kant's metaphysics lectures to have a better understanding of the concepts of practical and transcendental freedom used within the Critique of Pure Reason. Based on Kant's metaphysics lectures I will argue that practical freedom and transcendental freedom are different predicates that apply to our power of choice and that each comprises different sorts of abilities. Practical freedom concerns the abilities we use in choosing the motives for our actions, while transcendental freedom concerns (...) the ability to act otherwise than what nature necessitates through its causal laws. In terms of Kant's free will views, I will argue that Kant is neither a libertarian, nor a compatibilist, but instead is most accurately described as a moral necessitarian. (shrink)

In this dissertation, I provide an account of the protections to which most captive non-human animals are morally entitled when they participate in health-related research. At least in the animal ethics literature, it is uncontroversial that the protections currently afforded to captive research animals are inadequate. This has much to do with the fact that most animals who serve as research participants are 1) sentient and, thus, have important morally considerable interests; 2) unable to provide informed consent to their research (...) participation; and 3) seriously harmed as a result of their participation. Unsurprisingly, then, a number of authors have proposed alternative sets of protections that they take to be appropriately responsive to the morally considerable interests of research animals. However, none of the alternatives proposed ensures the ethically appropriate treatment of research animals because all are demonstrably more permissive than the set of protections governing research involving children. This seems problematic given that most animal research participants, like most pediatric research participants, are sentient and unable to provide informed consent for their research participation, and, furthermore, that these are the very characteristics that render children vulnerable — and so entitled to additional protections — in the context of research. I examine a number of reasons that might be thought to justify the discrepancy between the protections afforded to these two groups of research participants, and argue that no non-speciesist justification is forthcoming. Consequently, we ought to reflect upon how the protections currently in place for pediatric research participants might be extended to most animal research participants. I argue that most pediatric research protections, when suitably amended to account for relevant differences between most children and animals, can and should be extended to most animal research participants. I also demonstrate that doing so would require that substantial changes are made to most extant animal research studies. Since this, in turn, would require a radical transformation of the research enterprise as we know it, I also gesture towards how we might get from where we currently are to a truly just research enterprise.

In this dissertation, I explore the relationship between conceptual engineering and contextualism in philosophy. Conceptual engineering evaluates philosophical theories about concepts against whether they meet normative and political objectives, while contextualism highlights the influence of context on meaning and truth. I argue that conceptual engineering is subject to contextualism, rendering theories about concepts applicable only in specific contexts. The first chapter examines essentially contested concepts: concepts inevitably subject to contestation, owing to different, equally legitimate reasons philosophers may have for valuing (...) them. Nevertheless, within specific contexts, these concepts serve particular purposes, and conceptions aligned with those purposes better capture their significance. Chapter 2 examines the metaphysics of gender, challenging the view that gender categories are both subjective identities and objective social constructions. This view fails to address conflicts between how we subjectively identity and how we are objectively treated by others. I propose a contextualist perspective, according to which gender category meanings vary based on why we use them within particular contexts. In Chapter 3, I compare the methodology used in the metaphysics of gender with that used in the literature on the moral status of animals. I argue that the justification for employing conceptual engineering in the former applies equally to the latter. Accordingly, endorsing conceptual engineering in one case should lead us to do so in the other. Finally, I propose a contextualist account of moral status. (shrink)

In the first paper of this dissertation, I argue that bodily experiences, such as pain and itch experiences, emotional experiences, and mood experiences have intentional content that supervenes on their phenomenal character. I call these kinds of experiences normative-evaluative experiences. I argue that these experiences have intentional content that is determined, at least in part, by their positive and negative phenomenal characters. In the second paper of this dissertation, I examine the tracking representationalist theory of pain experience defended by Brian (...) Cutter and Michael Tye. On their view, the phenomenal character of pain experience supervenes on its intentional content, which is determined by tracking relations that obtain between the experience and certain properties in the environment. I argue that this theory is false. There are cases of structural mismatch between pain experience’s phenomenal character and the tracked properties Cutter and Tye identify. These cases show that pain experience’s phenomenal character does not supervene on the intentional content Cutter and Tye propose. I then argue that alternative versions of tracking representationalist theories of pain experience are unlikely to fare any better for similar reasons. Finally, in the third paper of this dissertation, following the view defended by David Chalmers in his paper “Perception and the Fall from Eden”, I argue that normative-evaluative experiences have two kinds of phenomenal content: a primitive Edenic content and a Fregean content. I propose a positive view of what these contents consist of. (shrink)

The past century has witnessed numerous methodological innovations in probabilistic and statistical methods of causal inference (e.g., the graphical modelling and the potential outcomes frameworks, as introduced in Chapter 1). These innovations have not only enhanced the methodologies by which scientists across diverse domains make causal inference, but they have also made a profound impact on the way philosophers think about causation. The philosophical issues discussed in this thesis are stimulated and inspired by these methodological innovations. Chapter 2 addresses the (...) question of how the holding of screening-off conditions for a causal model depends on the choice of variables. As bridge principles between probability and causation, screening-off conditions (especially the Causal Markov Condition) play a key role in causal inference. However, it has been known that these conditions may fail due to poor variable choice. My aim in this chapter is to further examine those constraints on variable choice that are deemed necessary for the satisfaction of screening-off conditions. The idea of a well-defined (hypothetical) intervention is also crucial for reliable causal inference. Chapter 3 explores the question of when interventions invoked in causal inference are “well-defined” or unambiguous, and how this requirement constrains the choice of cause-variables. I propose that an intervention is well-defined just in case the effect of interest is well-defined (under ideal interventions), and that the intervention can serve as a suitable means to identify that effect. Based on this proposal, several distinct types of ambiguous interventions are identified. Methodological progress in causal inference also poses the following question: Can such progress shed light on the ontology of causation? My answer is yes. In Chapter 4, I develop a Carnapian-pragmatist approach to the ontology of causation as an alternative to existing metaphysical approaches. I argue that, compared to traditional metaphysics, the pragmatist approach provides a superior picture of how the ontology and methodology of causation interact with each other in scientific practice. I conclude in Chapter 5 that the thing we call “causation” consists in both the right worldly infrastructure (e.g., screening-off patterns and possibilities for interventions) and appropriate ways of framing this infrastructure.

Neurodivergent people experience epistemic injustice, injustices that harm them in their capacity as knowers, but so far the epistemic injustice literature has mostly ignored this. This dissertation addresses this gap in knowledge in a novel way, using tools of formal epistemology. Bayesian network learning models that include modeled bias, communication style gaps, exclusion, and difference between people, are used to investigate testimonial injustice. Novel simultaneous Lewis-Skyrms signal games that include modeled bias, focus on success, gaps in way of thinking, exclusion, (...) and difference in material interests are used to investigate hermeneutical injustice, the subset of epistemic injustice that involves concepts important to an identity group being obscured both in and out of that identity group, due to the model's ability to track formation of meaning over time. The model results indicate that improvement first requires neurodivergent people be integrated into social networks with mixed neurotypes, but that this must be done with care to not isolate neurodivergent people among neurotypical people, and without tokenizing. Additionally, the models give evidence of social evolutionary forces that would contribute towards the presence of ableism in norms of communication, so it is recommended that action to combat ableism should include actions that create countervailing cultural evolutionary pressure, and aim to benefit anyone whom the action hopes to win over.

The present work is a critical examination of the Powerful Qualities Ontology. Categoricalism affirms that intrinsic properties are quiddistic or qualitative in nature, and Pure Powers Theory affirms that they are by nature powerful. The Powerful Qualities Ontology, though, affirms that intrinsic properties are both qualitative and powerful, and that by being a more robust ontology than both Categoricalism and Pure Powers Theory, it promises to account for more phenomena and solve more problems than these rival theories. Despite its advantages, (...) however, I challenge the feasibility of the Powerful Qualities Ontology. In chapter 1, I define important terms and provide a topography of the general debate on powers. In chapter 2, I discuss Martin and Heil’s Identity Theory, which is the standard account of the Powerful Qualities Ontology. I also discuss Jacobs’ Truthmaking View, which is supposed to be a restatement of Identity Theory. In chapter 3, I attempt to undermine Strawson’s case for Identity Theory. In chapter 4, I discuss Giannotti’s notion of aspects, which he introduces for the purpose of further articulating the Powerful Qualities Ontology. I also examine his Dual Aspect Account of powerful qualities. In chapter 5, I discuss Taylor’s collapse argument against Identity Theory. Taylor has argued that Identity Theory collapses into the Pure Powers View, and while I agree with him in important respects, I raise some doubts as to whether he is successful in establishing his conclusion. In chapter 6, I examine a couple of Grounding Theories of powerful qualities, and attempt to show how they are inadequate with respect to fundamental conceptual issues. Throughout the present work, I challenge the feasibility of several versions of the Powerful Qualities Ontology, but in chapter 7, I discuss topics relevant for future work on powerful qualities, as well as powers in general. Here I discuss alternative ontologies to Identity Theory, and different theories regarding the laws of nature that are relevant to powers ontologies. I conclude by suggesting that Powers Theorists should seriously consider more robust powers ontologies, as they are more promising than parsimonious ones in accounting for more phenomena and solving more problems.

One goal of feminist philosophy is to challenge unjust systems of power like patriarchy, which privilege some social groups while oppressing others. In this three-chapter dissertation, I argue that to achieve this goal, we need a better understanding of privilege and its implications. In chapter one, I raise objections to some existing philosophical accounts of privilege. These accounts are either too broad in defining privilege as always advantageous or they are vague regarding what privilege comprises. I provide an account of (...) privilege which clarifies that privilege is generally advantageous and that privilege includes tangible resources and options to do certain things or be a certain way. In chapter two, I utilize my account of privilege in the context of feminist debates on relational autonomy. Recently, strong substantive and constitutive accounts of relational autonomy have come under criticism. Critics argue these accounts generate perverse conclusions about oppressed agents. I show these accounts generate the same perverse conclusions about privileged agents. Critics also argue these accounts are poorly suited to achieve feminist goals, which are to combat systems of power and to offer an account for how autonomy is influenced by oppression and privilege. I defend an alternative account of relational autonomy given by Andrea Westlund and explain how it avoids the perverse conclusions while still achieving the second goal, as it can explain how oppression and privilege can influence autonomy. However, I argue that autonomy alone is not enough to achieve the first goal of combatting systems of power. In chapter three, I investigate the issue of vaccine hesitancy, where parents delay or refuse routine vaccinations for their children. Some empirical literature suggests a proportion of these parents are privileged. However, this literature lacks a clear definition of privilege. I supplement and strengthen this research with my account of privilege. I demonstrate how my account of privilege captures additional elements of parents’ privilege. Using my account of privilege, I show how privilege can potentially influence some of the reasons parents have for delaying or refusing vaccines. I also clarify how my discussion impacts public health policies aimed at addressing vaccine hesitancy. (shrink)

For many, the Nature/Nurture approach to development is a quaint figment of the past. We have moved on, one might think; everyone thinks that both categories are important for development, not merely one. The reality, however, is not so simple. In this dissertation, I argue that contemporary biology has not succeeded in getting out from under the shadow of Nature/Nurture, despite everyone being some sort of interactionist about development. The central aim of my project is to offer a form of (...) developmental interactionism worth having, which succeeds in shedding the pernicious aspects of Nature/Nurture. I begin by giving an overview of several candidate notions of interaction. One particularly promising notion is coupled interaction, where multiple variables co-determine each others' products, and cannot be well understood in isolation. I follow this up by examining the Central Dogma of genetics, and argue that the evidence supports the Extended Genome Thesis – the notion that the genome partially extends beyond the body in a sense that is analogous to coupled interaction. I then extend the analysis to the inherited/acquired distinction and argue that the distinction is meaningless. Traits are not inherited wholesale; they must be constructed anew in ontogeny. This means there is not a principled difference between whether the trait is inherited or acquired. My project culminates with an argument that the Nature/Nurture distinction itself is incoherent, based on the available evidence. The world simply isn't separable into distinct categories in the way Nature/Nurture implies; the reality tramples these conceptual boundaries. Neither category can do the work traditionally ascribed to it without its counterpart, and so those results should be understood as emerging from a coupled system. This system transcends the traditional internal/external divide, and so cannot be decomposed. Thus, Nature/Nurture is incoherent because there is no real difference between the components of one category and the components of another. Instead, the parts are coupled to form the ontogenetic (developmental) niche. To round out the project, I canvas some areas of science that I think are worth keeping a close eye on, given their capacity to enhance or harm the way understand development. (shrink)

The word “effective” has become the standard label attached to scientific theories these days. An effective theory allows us to make accurate predictions about a physical system at a certain (energy, length) scale while being largely ignorant of the details at more fundamental levels. One does not need to know anything about the deeper, quantum structure of water molecules to describe the macroscopic behaviour of waves or water in a glass. Although effective descriptions so broadly construed have been part of (...) research in physics since the earliest stages of modern science, it is particle physics that has most clearly relied on and brought to the fore some of the most interesting and admittedly puzzling aspects of this way of looking at theories. Indeed, the effective field theory (EFT) program in QFT has established itself as the most natural way to understand renormalisation and dissipate initial reservations about the status of these techniques by treating higher-order processes as contributions suppressed at lower energy scales. QFT is thus treated as the “effective” framework par excellence with the decoupling of scales constituting its permeating tenet. The goal of this project is to attempt a philosophical appraisal of EFTs as currently used in high energy physics as well as assess the possibility that the whole program eventually breaks down, i.e. fails to apply when certain preconditions do not hold. Accordingly, the dissertation is logically divided into two parts with the first two chapters dedicated to discussion of the relation between EFTs and traditional questions in the philosophy of science concerning the structure of scientific theories, the formulation and defence of scientific realism as well as its connection to possible ontological readings of EFTs. The second part constitutes an analysis of two well-known problems that have been accorded the status of crises in the physics literature: the hierarchy problem and the cosmological constant problem. Our main focus will be to uncover those assumptions responsible for undermining the validity of the EFT techniques in their respective context. In light of this analysis, we will ultimately lean towards a more cautionary or “reserved” approach to EFTs. (shrink)

This thesis addresses the tension in pragmatic cluster-randomized trials between their social value and the requirement to respect the autonomy of research participants. Pragmatic trials are designed to evaluate the effectiveness of treatments in real-world settings to inform clinical decision-making and promote cost-efficient care. These trials are often embedded into clinical settings and ideally include all patients who would receive the treatments under investigation as a part of routine care. Trialists increasingly adopt cluster-randomized designs—in which intact groups, such as hospitals (...) or clinics, are allocated randomly to study interventions—to simplify the inclusion of all patients. But including all-comers conflicts with the requirement to obtain written informed consent from research participants. Since informed consent is central to respecting patient autonomy, the question arises: how can the ends of autonomy and pragmatism be served simultaneously? Some philosophers argue that patients have an obligation to participate in clinical research and that this may negate consent requirements. I argue that while there may be grounds for a prima facie obligation for patients to participate in clinical research, no compelling argument has demonstrated that the obligation is enforceable. Others assert that broad application of a waiver of consent will facilitate the conduct of pragmatic cluster-randomized trials. I demonstrate that this proposal sharply conflicts with the historical origins of the waiver. I articulate a novel moral foundation for the use of a waiver of consent and show that when trials evaluate treatments delivered directly to patients, the autonomy interests at stake for participants are too substantial to permit its use. My solution draws a distinction between consent requirements in existing policy and consent as an autonomous authorization. As many pragmatic cluster-randomized trials are conducted in primary care settings with no research staff, I argue that patient autonomy can be promoted and protected using clinical-style consent, in which health providers seek verbal informed consent from patients and document it in the electronic health record. This approach has been associated with high rates of recruitment and, thus, may satisfy both requirements for social value and respect for autonomy. (shrink)

This dissertation offers a robust philosophical examination of a phenomenon that is morally, socially, and politically significant – microaggressions. Microaggressions are understood to be brief and routine verbal, behavioral, or environmental indignities that, whether intentional or unintentional, convey hostility toward or bias against members of marginalized groups. Microaggressions are rooted in stereotypes and/or bias (whether implicit or explicit) and are connected to broader systems of oppression. Microaggressions are philosophically interesting, since they involve significant ambiguity, questions about speech and communication, and (...) the ability for our speech to encode and transmit bits of meaning. Microaggressions prompt reflection about the nature of blameworthiness and responsibility, especially for unintended acts and harms. They involve questions about how we perceive and treat one another, and whether or not people are treated as true equals in our social and political worlds. For all of these reasons, microaggressions are a critical area in need of philosophical reflection, specifically reflection in feminist philosophy, philosophy of language, moral philosophy, and social and political philosophy. This dissertation seeks to advance the philosophy of microaggressions through three distinct aims: a conceptual aim (chapters 2 and 3), an epistemological aim (chapters 1 and 2), and a moral aim (chapters 4 and 5). The conceptual aim involves clarifying how we should understand and categorize microaggressions. The epistemological aim involves identifying some of the epistemological assumptions undergirding discussions of microaggressions in the literature, including assumptions made by critics of microaggression theory, and arguing for an alternative epistemological framework for theorizing about microaggressions. The moral aim involves better understanding the harms of microaggressions, including their role in reinforcing structures of oppression and unjust social hierarchy. Taken together, these chapters make some progress on the conceptual, epistemological, and moral questions that microaggressions generate, and which philosophers have not yet adequately analyzed. It thus offers a meaningful contribution to the conversations philosophers are beginning to have about the morally and politically salient phenomenon of microaggressions. (shrink)

This dissertation examines the significance of Johann Nikolas Tetens, a German empiricist philosopher working in the 1770's, to the theoretical philosophy of Immanuel Kant. I begin by examining Tetens' discussion of philosophical methodology in his 1775 essay \textit{Über die allgemeine speculativische Philosophie}. I make the case that Tetens' criticism of the methodology of the Scottish common sense philosophers and his subsequent attempt to incorporate what he takes to be their valuable insights into the approach of the broadly Wolffian philosophical tradition (...) provides important context for interpreting Kant's methodology in the \textit{Critique of Pure Reason}. I then examine two different cases of Tetens' applying this methodology in his 1777 text \textit{Philosophische Versuche über die menschliche Natur und ihre Entwickelung}. I argue that Tetens' discussion and critique of Humean causation in the fourth essay of the \textit{Philosophische Versuche} heavily influenced Kant's understanding of ``Hume's Problem'' and that many of the more obscure issues about the Kant-Hume relationship can be greatly clarified by giving sufficient attention to Tetens. I then examine Tetens' engagement with Thomas Reid's account of perception. I argue that Tetens' attempt to develop a representationalist account of perception which withstands Reid's objections leads him toward the view that representation requires object concepts and the problem of accounting for the origin of these concepts pushes Tetens to articulate an account of synthesis. In the final chapter, I examine Kant's proof that the real of appearances has intensive magnitude in the Anticipations of Perception. I raise several difficulties for the interpretation of the proof and then argue that Tetens' discussion of perception can provide us with the context for such a proof and the nature of the ``correspondence'' between sensation and objects.

This dissertation examines aspects of the interplay between computing and scientific practice. The appropriate foundational framework for such an endeavour is rather real computability than the classical computability theory. This is so because physical sciences, engineering, and applied mathematics mostly employ functions defined in continuous domains. But, contrary to the case of computation over natural numbers, there is no universally accepted framework for real computation; rather, there are two incompatible approaches --computable analysis and BSS model--, both claiming to formalise algorithmic (...) computation and to offer foundations for scientific computing. The dissertation consists of three parts. In the first part, we examine what notion of 'algorithmic computation' underlies each approach and how it is respectively formalised. It is argued that the very existence of the two rival frameworks indicates that 'algorithm' is not one unique concept in mathematics, but it is used in more than one way. We test this hypothesis for consistency with mathematical practice as well as with key foundational works that aim to define the term. As a result, new connections between certain subfields of mathematics and computer science are drawn, and a distinction between 'algorithms' and 'effective procedures' is proposed. In the second part, we focus on the second goal of the two rival approaches to real computation; namely, to provide foundations for scientific computing. We examine both frameworks in detail, what idealisations they employ, and how they relate to floating-point arithmetic systems used in real computers. We explore limitations and advantages of both frameworks, and answer questions about which one is preferable for computational modelling and which one for addressing general computability issues. In the third part, analog computing and its relation to analogue (physical) modelling in science are investigated. Based on some paradigmatic cases of the former, a certain view about the nature of computation is defended, and the indispensable role of representation in it is emphasized and accounted for. We also propose a novel account of the distinction between analog and digital computation and, based on it, we compare analog computational modelling to physical modelling. It is concluded that the two practices, despite their apparent similarities, are orthogonal. (shrink)

Around the world, millions of children are in need of parental care. In response to this global crisis, some philosophers defend a moral duty for prospective parents to adopt children rather than procreate. Challenges to the duty focus almost exclusively on parents’ desires to have biological children. However, reasons deriving primarily from one’s membership in a social group that favour procreation over adoption or oppose transracial adoptions are largely overlooked. In this dissertation, I examine whether group-based reasons could justifiably override (...) a duty to adopt for prospective parents who are members of racially oppressed groups. I ultimately argue that group-based interests cannot outweigh the needs of existing children for parental care, and thus provide further support for the duty to adopt. My thesis is divided into four chapters. In Chapter 1, I introduce a duty to adopt and argue that it is resilient against a series of proposed defeating conditions and foundational challenges. In Chapter 2, I develop three group-based reasons in favour of procreation that challenge the duty: reparative justice, racial solidarity, and cultural preservation. In Chapter 3, I argue that these reasons do not definitively support procreation over adoption and, instead, seem to favour adopting children either within or outside one’s racial group. I then identify remaining challenges to the duty that take issue with transracial adoptions and place a high value on children’s belonging in same-race families or in their communities of origin. In Chapter 4, I argue that the needs of individual children to receive timely parental care should not be compromised by groups’ interests and that children’s relationships with their communities of origin can be maintained in transracial or extra-communal adoptive placements.

This thesis explores the use of the concept 'realization' in the philosophy of mind. The primary focus is on the role realization plays in assessing or opposing identity theory. The history of the use of the concept of realization in the philosophy of mind is reviewed, and from that a set of desiderata to be used for assessing accounts of realization is extracted. The desiderata are applied to a sample account of realization proposed by Sydney Shoemaker. (2007) Next the application (...) of 'realization' in contemporary contexts is considered, focusing on the idea that mental kinds are, potentially, multiply realized. Based on interpretations of results from research in the relevant sciences this thesis considers two kinds of strategies used to object to multiple realization, (1) arguments against the concept of multiple realization: the Grain Argument (Bechtel and Mundale 1999), and Shapiro's Dilemma (Shapiro 2000), and (2) defeaters for alleged cases/examples of multiple realization proposed by Lawrence Shapiro and Thomas Polger: unification, individual differences, kind splitting, and abstraction and idealization. (Polger and Shapiro 2016) The thesis argues that, ultimately, these arguments hinge on the claim that there is no empirical evidence of multiply realized mental kinds. In response to this claim, the fourth chapter presents novel examples of multiple realization drawn from research in the cognitive neuroscience of language. There are three aspects from the study of language that are presented as examples of multiple realization: (1) language lateralization, (2) reading acquisition, and (3) second/multi- language learning. The analysis of these case studies applies Shoemaker's account of realization as a framework for describing the empirical data as cases of multiple realization. Objections to, and defeaters for, these cases are considered and rejected. The thesis concludes by raising the possibility that mental kinds are realized by mechanisms. This proposal involves drawing connections between traditional questions/views from the philosophy of mind with a current research program from the philosophy of science; the view is particularly important in the philosophy of neuroscience and the philosophy of biology, known as 'new mechanism'.

The goal of this dissertation is to reconstruct, critically evaluate, and apply the pluralism of Paul Feyerabend. I conclude by suggesting future points of contact between Feyerabend’s pluralism and topics of interest in contemporary philosophy of science. I begin, in Chapter 1, by reconstructing Feyerabend’s critical philosophy. I show how his published works from 1948 until 1970 show a remarkably consistent argumentative strategy which becomes more refined and general as Feyerabend’s thought matures. Specifically, I argue that Feyerabend develops a persuasive (...) case against rationalism, or the thesis that there exist normative and exclusive rules of scientific rationality. In Chapter 2, I reconstruct Feyerabend’s pluralism and detail its relationship to his humanitarianism and epistemological anarchism. I understand Feyerabend’s pluralism as the combination of the principles of proliferation and tenacity. I show the evolution and justification of these principles from Feyerabend’s early papers until the late 1970s. In Chapter 3, I defend Feyerabend’s pluralism from its most prominent criticisms. I then clarify that Feyerabend’s pluralism amounts to a conception of the logic of theory pursuit and modify his view using insights from C.S. Peirce, Pierre Duhem, and Michael Polanyi. From Peirce, I show how economic, sociological, and value-laden features of theory pursuit may be used to constrain proliferation and tenacity. From Duhem and Polanyi, I try to show the proper role of tacit knowledge within a Feyerabendian framework. Finally, I show what implications Feyerabend’s pluralism has for models of distributing funds within scientific communities. I contend that it provides a more promising model that the ‘well-ordered science’ proposal advanced by numerous philosophers and social scientists. Specifically, I aim to understand what taking Feyerabend’s pluralism seriously entails for principles of balancing funding allocation decisions and the role of peer-review in evaluating the potential success of research proposals. I conclude by suggesting future lines of research for further analyzing and applying Feyerabend’s pluralism. (shrink)

Philosophers of science have recently begun to pay more attention to scientific practice, moving away from the discipline’s focus on theories. The creation of the Society for Philosophy of Science in Practice in 2006, as well as the emergence of scholarship on experimental practice (e.g. Sullivan 2009; 2010; 2016) as well as on the tools scientists use to construct explanations and theories (e.g. Feest 2011) all point to a disciplinary shift towards a more practice-conscious philosophy of science. In addition, scholars (...) are realizing the potential social relevance of philosophy of science and identifying the obstacles that stand in the way of realizing said potential (e.g. Douglas 2010). The aim of this dissertation is to propose a novel descriptive framework for philosophy of science, one that rests on the idea that scientific practice should be described as accurately as possible so that philosophical discussions of science rest on a solid descriptive base and can more easily be of use in engaging users and practitioners of science. The dissertation is organized along the stages of developing what I call the dynamic-iterative model of scientific practice. In chapter 1, I clarify the project’s philosophical background and outline six conditions of adequacy on a descriptive model of science. These conditions allow me to evaluate the three descriptive models reviewed in chapter 2. Chapter 3 combines Nickles’ problem-solving view of science (1981) with core insights from the heuristics and biases literature into a workable version of the dynamic-iterative model. I then apply the model to the case of place cell research in chapter 4 as a test of the model’s usefulness and applicability. In chapter 5 I evaluate the model with respect to my six conditions and assess its strengths and weaknesses. The dynamic-iterative model is a flexible descriptive framework that not only allows for more complete philosophical analyses of cases than other current models, but also supports important practical applications.

This work is an analysis of F. P. Ramsey's philosophy of science. Twentieth-century philosophy of science was marked by attempts to consider the relation between scientific theories and our knowledge of the empirical world through considerations of abstract mathematical structure. Such considerations led Bertrand Russell to an account of the relation between our theoretical picture of the world and its real nature as a relation of structural similarity. Subsequently, Max Newman gave what has become a well-known logico-mathematical objection to this (...) account. William Demopoulos recently showed that Newman's problem applied not only to Russell's realist account, but also to a variety of otherwise disparate accounts of theoretical knowledge. The common element underlying these accounts is a conception of theories as abstract formal structures. Many such accounts have incorporated key elements of Ramsey's views, most notably the Ramsey-sentence. Moreover, Demopoulos has interpreted Ramsey's own view of theories as sharing the essential features of those abstract views, and therefore their common problem. My analysis aims to show that this abstract conception of theories does not adequately characterize Ramsey's view. Namely, his account of theories was not an attempt to do the epistemology of science in the fashion of Russell or Eddington, or of subsequent structuralist views that have adopted the Ramsey-sentence. I show this by a broader exposition of Ramsey's work on the nature of theories, comparing his seminal paper with his many other remarks on the nature and purpose of theories. I begin by discussing the historical context of Newman's objection, and a generalization of it that shows its broad applicability to abstract characterizations of theoretical knowledge. I then reconstruct Ramsey's view of theories, to show how far it extends beyond the Ramsey-sentence picture. Finally, I discuss the relevance of this view to contemporary debates concerning realism and instrumentalism. I characterize Ramsey's view as focused not on grounding our theoretical knowledge in abstract structure, but instead on demystifying the role of theoretical language and concepts in a theory's application to the world.

The Earth has not always been accompanied by its celestial partner, the Moon. In fact, the Moon was acquired by the Earth about 100 million years after the start of the solar system. It was acquired in the aftermath of a massive collision between the Earth and another planet, dubbed “Theia,” the mythological mother of the Greek goddess of the Moon. Most of the iron-rich cores of Earth and Theia merged almost immediately, while the rest of the two planets vaporized. (...) Some of the impact ejecta was lost, but enough remained in gravitationally bound orbit around what was then $ 98\% $ of current-sized Earth. What remained of the impact eject derived from the outer, silicate portion of the Earth, cooled rapidly, condensed and accreted to form the body we are so accustomed to seeing in our sky. I want to know how we can know all of that. Hempel (1942) famously argued that theories and hypotheses concerning history cannot meet the standard of a true scientific theory, and can, at best, only offer explanation sketches, i.e. how-possible scenarios, and at worst, amount to nothing more than in-principle untestable tales, i.e. just-so stories. This seed of distrust concerning scientific theories that have a narrative form has persisted, even if no one still thinks that Hempel's explication of what makes a theory justly scientific is adequate. Yet we do seem to have much genuine scientific knowledge of the deep past. Such knowledge must, then, be justified or confirmed on the basis of some alternative inferential methodology that both makes up for the inability of historical scientists to perform controlled laboratory tests on past complex events and which makes the narrative form of theories inessential. This dissertation develops a new empiricist framework that answers Hempel’s challenge to the untestability of stories concerning the deep past. (shrink)

A singular thought can intuitively be understood as a thought that is directly about a particular thing, e.g., a non-conceptual thought about B.B. King, Mont Blanc, or your most beloved pet. The consensus within the singular thought literature has been that Gareth Evans (1982) develops a theory of singular thought throughout his posthumously published work The Varieties of Reference. However, Evans never claims to be developing a theory of singular thought, nor does the locution ‘singular thought’ appear more than a (...) handful of times throughout the work. The singular thought literature lacks any substantial exegetical engagement with the theory of singular thought that Evans argues for — including an account as to why Evans should be interpreted as offering a theory of singular thought, as well as how he should be so interpreted. The interpretation of Evans that I wish to argue for is one according to which a singular thought (for Evans) is an object-dependent thought, the thinking of which requires the satisfaction of Russell’s Principle. Liberalism is the thesis that there is no general acquaintance constraint on singular thought. Many contemporary Liberalists, including semantic instrumentalists and cognitivists, are quick to argue that Evans’ theory of singular thought is incorrect. What I seek to demonstrate is that, armed with a proper understanding of Evans’ theory of singular thought, most recent Liberalist critiques of Evans are unsuccessful because they either misevaluate or misidentify the explicandum with which Evans was concerned.

With the cure rate for many pediatric malignancies now between 70% and 90%, infertility becomes an increasingly important issue. Strategies for preserving fertility in girls and adolescent women occur in two distinct phases. The first phase includes oophorectomy and cryopreservation of ovarian cortex slices or individual oocytes; ultrasound-guided needle aspiration of oocytes, with or without in vitro maturation, followed by cryopreservation; and ovarian autografting to a distant site. The second phase occurs if the woman chooses to pursue pregnancy, and includes (...) IVM of the oocytes, followed by in vitro fertilization and transfer of any created embryos to the woman's uterus. For ovarian autografting, the woman would undergo menotropin ovarian stimulation and retrieval of matured oocytes. The ethical challenges with each of these phases are many of fertility preservation and include issues of informed choice. The lack of proven benefit with these strategies and the associated potential physical and psychological harms require careful attention to the key elements of informed choice, which include decisional capacity, disclosure, understanding and voluntariness, and to the benefits of in-depth counseling to promote free and informed choice at a time that is emotionally difficult for the decision makers.

Through a detailed analysis of the various modes of argumentation employed by Aristotle throughout his natural scientific works, I aim to contribute to the growing scholarship on the relation between Aristotle’s theory of science and his actual scientific practice. I challenge the standard reading of Aristotle as a methodological empiricist and show that he permits a variety of non-empirical arguments to support controversial theses in properly scientific contexts. Specifically, I examine his use of logical (logikôs) argumentation in the discussion of (...) mule sterility in Generation of Animals II 8, rational (kata ton logon) argumentation in his discussion of cardiocentrism throughout the biological works, and the method of division in Posterior Analytics II 13.

In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I (...) contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical kinds and species) do; and, in light of this fact, I conclude that the normative ideal of natural classification—i.e. classifying real or natural kinds—is not appropriate as a general strategy for psychiatry. In the conclusion to this dissertation I propose an alternative way forward. Rather than assuming a priori that psychopathological phenomena cluster together into kinds, a more tractable and theoretically promising approach would be to first explain how particular kinds of experiences and behaviours—e.g, hallucinations, delusions, disorganized thinking, mania, low mood, etc.—are produced.

The current view of the relationship between areas of the mind-brain sciences is one where cross-disciplinary collaboration is required to advance claims about the mind-brain that stand on firm epistemic footing. My goal in this dissertation is to analyze what it means for information from different areas of science to fit together to produce strong epistemic claims by addressing how and to what extent claims about the mind-brain are corroborated in scientific practice. Philosophers of science have advanced various concepts of (...) the notion of fitting together information from different areas of science and its relation to scientific progress (e.g., Bickle, 1998, 2003, 2006; Darden and Maull, 1977; Mitchell, 2002, 2003; Mitchell and Dietrich, 2006; Nagel 1949, 1970, 1979; Piccinini and Craver, 2011; and Roskies, 2010). However, each concept of fitting together is vague and subject to multiple clarificatory questions. To get a handle on the notion of fitting together, I introduce the term ‘interdisciplinary corroboration’ as a placeholder for the various accounts of fitting together to facilitate my investigation of how claims about the mind-brain are corroborated in scientific practice. I argue review papers are a good place to begin analyzing interdisciplinary corroboration; accordingly, I conduct a two-part analysis of a review paper by Eichenbaum (2013) entitled ‘Memory on Time’. I use the lessons from my analysis to develop and advance a methodology for philosophers of science interested in knowledge production for evaluating review papers for corroboration in the mind-brain sciences.

Science is a process, through which theoretical frameworks are developed, new phenomena defined and discovered, and properties of entities tested. The goal of this dissertation is to illustrate how high-energy physics exemplified the process of theory construction from the 1950s to 1970s, and the promising ways in which it can continue to do so today. The lessons learned from the case studies examined here can inform future physics, and may provide methodological clues as to the best way forward today. I (...) examine the discovery of parity nonconservation in weak interactions, the emergence of Yang-Mills theories as the foundation of the standard model, and contemporary precision testing of quantum electrodynamics. In each of these cases, I examine the details of the physicists’ practice to draw conclusions regarding the epistemology behind successful episodes of theory construction. I reconstruct the methodology of each episode in order to find generalizable lessons to apply to contemporary issues at the frontiers of the search for a theory of quantum gravity. In order to understand the many moving parts in each case study, I introduce a new terminology to distinguish the “parts” of a scientific discipline, inspired by the literature on scientific modelling. These terms—theoretical framework, dynamical model, phenomenological model, experiment, and mathematical tools—are meant to aid in investigating other quantitative scientific disciplines beyond high-energy physics. Ultimately, high-energy physics is at its best when various avenues of theoretical ideas are being pursued, spurring the development of new mathematical techniques to use as tools, and new ideas are quickly and vigorously tested experimentally. Proliferation of new ideas in response to theoretical developments is characteristic of the era of construction of the standard model, and is still ongoing in precision testing of quantum electrodynamics today.

Although logical empiricism is now mostly decried, their naturalist claim that the content of a theory can be read off from its structure, without any philosophical considerations needed, still supports traditional strategies to escape cases of underdetermination. The appeal to theoretical equivalence or to theoretical virtues, for instance, both assume that there is a neutral standpoint from which the structure of the theories can be analyzed, the physically relevant from the superfluous separated, and a comparison made between their theoretical content (...) and virtues. In my dissertation, I examine the presuppositions upon which such strategies depend. I argue that the methodological principle underlying them, according to which theories with no superfluous structure should be preferred, is unpractical, for what constitutes relevant structure is determined by epistemic considerations about the aim of scientific theories. In chapter 1, I analyze the claim that theories with ordinary bosons and fermions are theoretically equivalent to theories with exotic `paraparticles'. I argue that this claim does not do justice to the latter, as the proof is formulated in a vocabulary parochial to the former and thus favors one of the theory while giving an impoverished version of the second. In chapter 2, I examine recent arguments to the effects that any interpretation of Quantum Mechanics that can offer a no-go theorem against paraparticles possesses an explanatory advantage over other interpretations and should, as such, be favored over others. Given that most physicists consider paraparticles as surplus structure whose non-observation does not require an explanation, I evaluate arguments of both sides and suggest a third way to approach the question. Finally, in chapter 3, I turn my attention to methods for excluding another kind of unphysical structure, mathematical artifacts, from rival dark matter models. Simulations are our only window into what rival models predict about the universe’s structure. But for them to play a useful role in generating knowledge, we need to distinguish reliably between real predictions and artifacts. I argue that robustness analysis fails to fulfill this task. I propose in its place another methodology, that of crucial simulations. (shrink)

One recent debate in philosophy of physics has centered whether quantum particles are individuals or not. The received view is that particles are not individuals and the standard methodology is to approach the question via the structure of quantum theory. I challenge both the received view and the standard methodology. I contend not only that the structure of quantum theory is not the right place to look for conditions of individuality that quantum particles may or may not satisfy, but also (...) that there is an important role for traditional metaphysics to play. Consequently, my work brings together the philosophy of physics and traditional metaphysics literatures to shed new light on the debate over the individuality of quantum particles. I defend a set of conditions of individuality and argue that quantum particles satisfy these conditions thereby defending the view that particles are individuals in opposition to the received view. I also challenge a second feature of the standard methodology insofar as I challenge the significance of the Principle of the Identity of Indiscernibles in terms of which much discussion in the philosophy of physics literature is framed. My work is significant in a number of additional ways as well. My work implies that the dominant explanation for quantum statistics in terms of non-individuality is incorrect and it also undermines the ontic-structural realists metaphysical underdetermination challenge to the scientific realist.

The central question for this dissertation is, how do we do moral philosophy well from within a broadly naturalist framework? Its main goal is to lay the groundwork for a methodological approach to moral philosophy that integrates traditional, intuition-driven approaches to ethics with empirical approaches that employ empirical data from biology and cognitive science. Specifically, it explores what restrictions are placed on our moral theorizing by findings in evolutionary biology, psychology, neuroscience, and other fields, and how we can integrate this (...) data while still offering a fully normative account of ethics. To that end, the dissertation explores the methodological assumptions behind both traditional and more empirical or experimental approaches to ethics, to find where these assumptions cannot be properly supported and need to be re-examined. Chapter 1 explores the science-based objections that have been raised to traditional approaches, with a particular focus on questions concerning the reliability of moral intuitions. Chapter 2 examines three fundamental assumptions supporting the empirical approach to moral philosophy, and how those assumptions ultimately do not fit with how we ought to understand the project of ethics. In chapter 3, I discuss the fact/value distinction, and the restrictions that are placed on our moral theorizing by our commitment to this distinction. Chapter 4 offers a defense of ‘companions in guilt’ arguments, and uses these arguments to draw an analogy between moral philosophy and epistemology that will be used to help defend moral philosophy against empirical debunking arguments. Chapter 5 explores the ways in which epistemologists’ methods of incorporating empirical data into their research while maintaining the normativity of their accounts can be adapted to allow moral philosophers to do the same, and brings together the various methodological concerns addressed up to this point to lay out a methodological approach I call empirically-informed moral philosophy.

I survey the options for understanding the nature of the wave-function in the setting of the relativistic collapse models recently developed by Tumulka. Some of the options involve surprising features, such as backwards causation or locality.

I have defended the view that an interpretation of QFT should be based on a rigorous axiomatic variant of the theory. There are two significant objections to this position: that no realistic model of any set of axioms has ever been constructed and that there is nothing to be gained from pursuing the axiomatic program for QFT. In the course of defending myself from these objections, I will discuss some of the recent literature on constructing models for interacting systems.

The working assumption amongst most philosophers of QFT appears to be that algebraic QFT, and not the "Lagrangian" QFT of the working physicist, is the proper object of philosophical and foundational study. I argue that this assumption is unmotivated, and fails to take into account important features of the post-1960s development of Lagrangian QFT. From a modern perspective the two forms of QFT are better seen as rival research programs than as variant formulations of one theory; furthermore, the Lagrangian research (...) program is overwhelmingly supported by experiment.

I consider what non-relativistic quantum field theories suggest about the intertheoretic relations between classical and quantum theories of particles and fields, both in the presence and in the absence of gravitational effects. In the absence of gravity, interacting NQFTs exist for which Haag's theorem, the CPT theorem, and the Spin Statistics theorem all do not apply; and while the Reeh-Schlieder theorem is valid, it does not have the same implications that it does in the relativistic context. Moreover, a consistent NQFT (...) exists that includes gravitational effects. This "Newtonian" quantum theory of gravity is an example of an NQFT in a classical curved spacetime, and is not afflicted by the conceptual problems surrounding relativistic QFTs in curved spacetimes. These examples provide clues to how the fundamental theories in physics relate to each other and to the quest of formulating a fully relativistic quantum theory of gravity. (shrink)

Recently, Simon Saunders has applied Quine's account of discernibility to the theory of identical particles, ultimately to argue that quanta can be weakly discernible. I want to expand on this work along two axes. First, to explain how the results apply to higher kinds of statistics -- 'quarticles'. Second, to dispute the claim that quanta are weakly discernible: I question whether the operators used to discern the particles do not represent the properties that they are claimed to.

We consider the claim that decoherence explains the emergence of classicality in quantum systems, and conclude that it cannot. We show that, given a universe composed of a variety of subsystems, some of which are macroscopic and subject to decoherence-inducing interactions, and some of which are microscopic, the macroscopic subsystems do not display any distinctively classical behavior. Therefore, a universe in which macroscopic and microscopic do display distinct behavior must be in a very special, highly nongeneric quantum state.

A discussion of "History of science without philosophy of science is blind, and philosophy of science without history of science is empty".

One of the most unsettling problems in the history of philosophy examines how mathematics can be used to adequately represent the world. An influential thesis, stated by Eugene Wigner in his paper entitled "The Unreasonable Effectiveness of Mathematics in the Natural Sciences," claims that "the miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve." Contrary to this view, this thesis delineates and implements (...) a strategy to show that the applicability of mathematics is very reasonable indeed. I distinguish three forms of the problem of the applicability of mathematics, and focus on one I call the problem of uncanny accuracy: Given that the construction and manipulation of mathematical representations is pervaded by uncertainty, error, approximation, and idealization, how can their apparently uncanny accuracy be explained? I argue that this question has found no satisfactory answer because our rational reconstruction of scientific practice has not involved tools rich enough to capture the logic of mathematical modelling. Thus, I characterize a general schema of mathematical analysis of real systems, focusing on the selection of modelling assumptions, on the construction of model equations, and on the extraction of information, in order to address contextually determinate questions on some behaviour of interest. A concept of selective accuracy is developed to explain the way in which qualitative and quantitative solutions should be utilized to understand systems. The qualitative methods rely on asymptotic methods and on sensitivity analysis, whereas the quantitative methods are best understood using backward error analysis. The basic underpinning of this perspective is readily understandable across scientific fields, and it thereby provides a view of mathematical tractability readily interpretable in the broader context of mathematical modelling. In addition, this perspective is used to discuss the nature of theories, the role of scaling, and the epistemological and semantic aspects of experimentation. In conclusion, we argue for a method of local and global conceptual analysis that goes beyond the reach of the tools standardly used to capture the logic of science; on their basis, the applicability of mathematics finds itself demystified.

Faith healing deaths occur infrequently in Canada, but when they do they pose a considerable challenge for criminal justice. Similar to caregivers who absent-mindedly and fatally forget a child in a hot vehicle, faith healers do not intentionally harm their children. It can seem legally excessive and unjust to prosecute achingly bereaved parents. But unlike ‘hot-car’ deaths, faith healing parents are not absent minded in the deaths they cause. Rather, significant deliberation and strength of will is necessary to treat their (...) child’s ailment with faith alone. Two different Criminal Code provisions can be brought to bear upon these deaths, namely, s. 215 ‘Failing to provide the necessaries of life’ and s. 219 ‘Criminal negligence’. From a public, medical, and scientific perspective treating potentially fatal ailments with ‘faith’ and ‘prayer’ seems like reckless endangerment, giving apparent justification to the more serious criminal negligence charge. But, the fault element in the criminal negligence offence continues to be a vexing issue in Canadian jurisprudence. People accused of negligence-based offences are commonly held to the standard of what a reasonable person might predictably have done in similar circumstances. While it is unnecessary for the impartial trier of fact to conceive of faith healing as ‘reasonable’, it is an open question whether faith healers are sufficiently unreasonable to warrant serious criminal condemnation and possible incarceration when their course of action causes death. Is it justifiable to think of faith healers who cause death as criminally unreasonable? That is, do they depart markedly enough from the standard that criminal negligence is rightly attributed to them? Public attitudes toward religion, religious fundamentalism, and healthcare must be considered when trying to discern what a reasonable person does when treating an ailing child at risk of death.

The focus of my dissertation is a general and comprehensive examination of Locke’s view of divine power. My basic argument is that John Locke is a theological voluntarist in his understanding of God’s creative and providential relationship with the world, including both the natural and moral order. As a voluntarist, Locke holds that God freely imposes both the physical and moral laws of nature onto creation by means of his will: this contrasts with the intellectualist perspective in which the laws (...) of nature emerge from the essences of things. For Locke, there are no intrinsically necessary laws in the created order: both physical and moral laws are arbitrary determinations of the divine will. While these laws are not intrinsically necessary, they are hypothetically necessary. Hypothetical necessity involves things that could have been otherwise, but which are necessary based on the supposition of a free action and other relevant conditions pertaining to the actor. Concerning God, we can understand hypothetical necessity in the following way: □ [ → Y]. X is a variable that ranges over a subset of contingent propositions about actions. ‘P’ is the proposition ‘God is perfect’. And Y is any proposition that is a necessary consequent of both X and P. In any possible world in which God performs X, it is the case that Y will obtain. Supposing that God decides to create beings like us, God must of necessity craft the moral laws of nature in a way that harmonizes with our nature. What grounds this necessity is that God must act consistently with the perfection of the divine nature: to give us a different law would be less than perfect. Furthermore, I argue that certain physical laws of nature – those that help to realize our nature – are also hypothetically necessary. (shrink)

The concept of nature (phusis) is ubiquitous in Aristotleʼs work, informing his thinking in physics, metaphysics, biology, ethics, politics, and rhetoric. Much of scholarly attention has focussed on his philosophical analysis of the concept wherein he defines phusis as “a principle or cause of being changed and of remaining the same in that to which it belongs primarily, in virtue of itself and not accidentally” (Phys. 192b21-23) and the implications this has in various parts of his philosophy. It has largely (...) gone unnoticed, or unremarked, that this is not the only understanding of phusis present in his thinking. This thesis argues that in addition to his philosophical understanding of phusis, there is another, pre- theoretic understanding at work. " After unpacking this pre-theoretic understanding, which is best described as ʻthe natural world,ʼ I argue that there are three tensions stemming from this. First, the natural world is, at times, placed in opposition to the human realm, while at other times, the humans are included as part of nature. Second, nature is considered to be both a static state and a dynamic process of change depending on the context, which prompts Aristotle to claim, in different places, that ageing and dying are both natural and unnatural. Third, nature is treated both as an ideal and as something to be overcome. This thesis attempts to bring to light Aristotleʼs pre-theoretic understanding of phusis and to draw out these three tensions. In the end, I suggest that modern confusions about nature may be informed by considering how they are reflected in the work of the first great thinker about nature, Aristotle. (shrink)

Hume’s “impressions of reflection” is a category made up of all our non-sensory feelings, including “the passions and other emotions.” These two terms for affective mental states, ‘passion’ and ‘emotion’, are both used frequently in Hume’s work, and often treated by scholars as synonymous. I argue that Hume’s use of both ‘passion’ and ‘emotion’ in his discussions of affectivity reflects a conceptual distinction implicit in his work between what I label ‘attending emotions’ and ‘fully established passions.’ The former are the (...) transient, changeable, valenced feelings that flow between perceptions and constitute their felt nature and impulse. The latter are the particular passions fully realized, with characteristic valence, and analyzed by Hume in terms of their particular belief structures and relations between ideas and impressions understood to be constituent of particular passions. The term ‘emotion’ for Hume generally denotes either the attending feeling, sometimes distinct from the passion (particularly as ‘passion’ is being used to include the associated beliefs, causes and objects), or as a synonym for a particular passion, typically when Hume is primarily referring to the felt nature of the passion. Generally speaking, ‘passion’ is a more cognitive category of affective mental state, while ‘emotion’ is more sensationalist. I will further argue that when we grant Hume the emotion/passion distinction, he can accommodate both highly sensationalist and highly cognitivist understandings of affective mental states. I finish with the application of my distinction to two key topics in Hume studies: his sympathy mechanism, and his theory of belief and motivation. (shrink)

This essay examines the relationship between ordinary empirical judgments and our scientific worldviews. It is concerned with how ordinary judgments (and the primitive frameworks in which they are formulated) might be usefully integrated into an account of epistemological progress, both of our personal views and scientific theories, such that the sciences (especially modern theories of space and time) can reasonably be thought as being informed by, and evolving out of, at least some of the various pre-scientific views they have replaced. (...) We examine our normal perceptual judgments of magnitude, position, orientation, and displacement in the hope of uncovering the logical, conceptual, and empirical relations that exist between such judgments (as well as the views of the world they presuppose) and our sophisticated understandings of space, time, and motion in physical theory. This research contends that experience and a rich type of conceptual analysis—one that examines the presuppositions that make possible the application of concepts in empirical contexts—together provide the framework within which a rational account of such relations can be proposed. The project thus defends a form of empiricism, but one distinct from classical forms (be they British empiricism, Russellian empiricism, or logical empiricism)—rather a slightly modified version of Anil Gupta’s “Reformed Empiricism”. This empiricism is capable of avoiding the logical excesses and errors of earlier forms, whilst providing an account of how a set of basic empiricist principles might be extended from their context in general epistemology to recalcitrant problems in the philosophy of science, such as the problem of our formal knowledge, the problem of the communicability of observation, and the rationality of theoretical progress. Such an extension offers a comprehensive account both of our ordinary and scientific knowledge. (shrink)

In this dissertation, I consider from a philosophical perspective three related questions concerning the contribution of mathematics to scientific representation. In answering these questions, I propose and defend Carnapian frameworks for examination into the nature and role of mathematics in science. The first research question concerns the varied ways in which mathematics contributes to scientific representation. In response, I consider in Chapter 2 two recent philosophical proposals claiming to account for the explanatory role of mathematics in science, by Philip Kitcher, (...) and Otavio Bueno and Mark Colyvan. My novel and detailed critique of these accounts shows that they are too limited to encompass the diverse roles of mathematics in science in historical and contemporary scenarios. The conclusion is that any such philosophical account should aim to faithfully capture the structure of our theories and their use in applied contexts. This insight prompts the second question guiding this dissertation that I consider in Chapter 3, regarding a viable philosophical account of the role of mathematics in scientific theories. I respond by proposing a modified form of the reconstructive frameworks for philosophical analysis developed by Rudolf Carnap for theoretical entities. I propose three amendments to Carnap’s account: i) a semantic view for the representation of theories, ii) a careful consideration of instances of the use of theory in representing target systems, and iii) consideration of the practical complexity of relating theory to experimental data. The final research question for this dissertation asks what, if anything, we can legitimately conclude about the nature of theoretical entities invoked by a theory in light of its success in representing phenomena. In the backdrop of the Carnapian frameworks proposed in Chapter 3, I argue that contemporary ontological debates in the philosophy of science are largely premised on an acceptance of Willard Quine’s epistemological outlook on the world and a dismissal of Carnap’s approach, which can be used to offer a satisfactory deflationary resolution. This is in the service of my contention that a Carnapian attitude to central issues in the philosophy of science is decidedly preferable to the route championed by Quine. (shrink)

Heuristics are often invoked in the philosophical, psychological, and cognitive science literatures to describe or explain methodological techniques or "shortcut" mental operations that help in inference, decision-making, and problem-solving. Yet there has been surprisingly little philosophical work done on the nature of heuristics and heuristic reasoning, and a close inspection of the way(s) in which "heuristic" is used throughout the literature reveals a vagueness and uncertainty with respect to what heuristics are and their role in cognition. This dissertation seeks to (...) remedy this situation by motivating philosophical inquiry into heuristics and heuristic reasoning, and then advancing a theory of how heuristics operate in cognition. I develop a positive working characterization of heuristics that is coherent and robust enough to account for a broad range of phenomena in reasoning and inference, and makes sense of empirical data in a systematic way. I then illustrate the work this characterization does by considering the sorts of problems that many philosophers believe heuristics solve, namely those resulting from the so-called frame problem. Considering the frame problem motivates the need to gain a better understanding of how heuristics work and the cognitive structures over which they operate. I develop a general theory of cognition which I argue underwrites the heuristic operations that concern this dissertation. I argue that heuristics operate over highly organized systems of knowledge, and I offer a cognitive architecture to accommodate this view. I then provide an account of the systems of knowledge that heuristics are supposed to operate over, in which I suggest that such systems of knowledge are concepts. The upshot, then, is that heuristics operate over concepts. I argue, however, that heuristics do not operate over conceptual content, but over metainformational relations between activated and primed concepts and their contents. Finally, to show that my thesis is empirically adequate, I consider empirical evidence on heuristic reasoning and argue that my account of heuristics explains the data. (shrink)

This dissertation attempts to make contributions to normative ethics and to the history of philosophy. First, it contributes to the defense of consequentialist ethics against objections grounded upon the value of loving relationships. Secondly, it provides the first systematic account of John M. E. McTaggart’s ethical theory and its relation to his philosophy of love. According to consequentialist ethics, it is always morally wrong to knowingly do what will make the world worse-off than it could have been. Many consequentialists also (...) recognize that love is one of the most important goods worth pursing for its own sake and so this implies a strong duty to promote love. Recently, however, philosophers have outlined what I call the “love-based objection.” It argues that consequentialism ought to be rejected on its own terms because a commitment to maximizing aggregate overall goodness precludes forming the kinds of commitments necessary for highly valuable loving relationships. Other philosophers, however, have argued that a particular kind of consequentialist theory that recognizes the intrinsic value of love and that restricts evaluations based on maximizing goodness to only the most fundamental realms of moral evaluation and guidance overcomes the love-based objection. While philosophers have indicated how to overcome the objection through sophisticated consequentialism, the task of constructing a plausible version of such a system is currently ongoing. This dissertation argues that, more than fifty years before this contemporary debate started, McTaggart outlined a version of consequentialism called “Ideal Utilitarianism” that can overcome recent love-based objections in the way suggested by Railton and Mason. McTaggart’s work in moral philosophy, therefore, has a previously unrecognized relevance to contemporary issues in normative ethics and so his contributions ought to be considered alongside other, currently more prominent, ethicists of his day such as Hastings Rashdall and G. E. Moore. (shrink)

This dissertation makes two primary contributions. The first three chapters develop an interpretation of Carnap's Meta-Philosophical Program which places stress upon his methodological analysis of the sciences over and above the Principle of Tolerance. Most importantly, I suggest, is that Carnap sees philosophy as contiguous with science—as a part of the scientific enterprise—so utilizing the very same methods and subject to the same limitations. I argue that the methodological reforms he suggests for philosophy amount to philosophy as the explication of (...) the concepts of science through the construction and use of suitably robust meta-logical languages. My primary interpretive claim is that Carnap's understanding of logic and mathematics as a set of formal auxiliaries is premised upon this prior analysis of the character of logico-mathematical knowledge, his understanding of its role in the language of science, and the methods used by practicing mathematicians. Thus the Principle of Tolerance, and so Carnap's logical pluralism, is licensed and justified by these methodological insights. This interpretation of Carnap's program contrasts with the popular Deflationary reading as proposed in Goldfarb & Ricketts. The leading idea they attribute to Carnap is a Logocentrism: That philosophical assertions are always made relative to some particular language, and that our choice of syntactical rules for a language are constitutive of its inferential structure and methods of possible justification. Consequently Tolerance is considered the foundation of Carnap's entire program. My third chapter argues that this reading makes Carnap's program philosophically inert, and I present significant evidence that such a reading is misguided. The final chapter attempts to extend the methodological ideals of Carnap's program to the analysis of the ongoing debate between category- and set-theoretic foundations for mathematics. Recent criticism of category theory as a foundation charges that it is neither autonomous from set theory, nor offers a suitable ontological grounding for mathematics. I argue that an analysis of concepts can be foundationally informative without requiring the construction of those concepts from first principles, and that ontological worries can be seen as methodologically unfruitful.

The enactive approach to cognition and consciousness offers a valuable alternative to the standard approaches dominant in the sciences of mind. As an embodied account, enactivism incorporates theoretical perspectives on the body from phenomenology, cognitive science, and biology, which provides a unique interpretation of embodiment with critical insight into the embodied nature of cognition and consciousness. Nonetheless, I argue that several revisions are required to make enactivism viable within the context of the sciences of mind. The enactive account of subjectivity (...) is problematic, in light of arguments developed in Maurice Merleau-Ponty’s later texts, because it is implicitly dualistic. I demonstrate that this implicit dualism can be resolved by incorporating the conceptual framework of flesh that Merleau-Ponty introduces in his later works. However, this new framework presents a challenge of understanding how body can break with world in experience. I provide a solution to this problem by way of developing revisions to the enactive account of cognition, which I argue is problematic in its generality. I offer a new interpretation of enactive cognition modelled on structural flexibility that overcomes the difficulties of the previous account. These revisions to enactive cognition provide a way of understanding how body can break with world, resulting in an account of the enactive body as expressing a massive integration of its different ways of being in the world, as cognitive, conscious, affective, and agentive. These revisions provide a more consistent and plausible articulation of the enactive approach that is more amenable to guiding the sciences of mind. (shrink)

In this thesis, I examine the metaphysical debate between the A-theory and the B-theory of time, first by elaborating upon its proper characterization, and then by examining the sorts of evidence that are often thought to be germane to it. This debate, as I see it, is about whether or not time passes in any objective sense: the A-theory holds that it does, while the B-theory holds that it does not. I identify two opposing conceptions of time—that of the “time (...) of ordinary experience” on one hand, and that of “scientific time” on the other—and argue that the tension between them is the driving force behind this debate. I then examine two aspects of “evidence” from the time of ordinary experience: the phenomenological experience of time and the linguistic experience of time. It is often supposed, by both A- and B-theorists alike, that these sorts of evidence lend credence to the A-theory of time, since ordinary experience suggests that time passes. I hope to discredit this presumption, and so challenge the very framework in which this debate is so often carried out. In particular, by closely examining both of these kinds of experience—phenomenological and linguistic—in turn, I hope to provide a partial argument to the effect that the ordinary experience of time as a whole does not favour the A-theory over the B-theory of time. In the case of the phenomenological evidence, this is because the A-theory is just as inconsistent with such evidence as is the B-theory of time; in the case of the linguistic evidence, this is because the B-theory is equally consistent with such evidence as is the A-theory of time, particularly once it is revealed that a certain key assumption is tacitly accepted by both sides of the debate. Because of the popularity of the claim that the ordinary experience of time favours the A-theory, I take this conclusion to be something of a modest defence for the B-theory of time. (shrink)

This thesis considers the following problem: What methods should the epistemology of science use to gain insight into the structure and behaviour of scientific knowledge and method in actual scientific practice? After arguing that the elucidation of epistemological and methodological phenomena in science requires a method that is rooted in formal methods, I consider two alternative methods for epistemology of science. One approach is the classical approaches of the syntactic and semantic views of theories. I show that typical approaches of (...) this sort are inadequate and inaccurate in their representation of scientific knowledge by showing how they fail to account for and misrepresent important epistemological structure and behaviour in science. The other method for epistemology of science I consider is modeled on the methods used to construct valid models of natural phenomena in applied mathematics. This new epistemological method is itself a modeling method that is developed through the detailed consideration of two main examples of theory application in science: double pendulum systems and the modeling of near-Earth objects to compute probability of future Earth impact. I show that not only does this new method accurately represent actual methods used to apply theories in applied mathematics, it also reveals interesting structural and behavioural patterns in the application process and gives insight into what underlies the stability of methods of application. I therefore conclude that for epistemology of science to develop fully as a scientific discipline it must use methods from applied mathematics, not only methods from pure mathematics and metamathematics as traditional formal epistemology of science has done.

In this dissertation I examine ethical issues that concern fertility preservation (FP) technologies for women from a feminist perspective. FP technologies involve the removal, cryopreservation and subsequent storage of reproductive materials for future use. The aim of these technologies is to preserve the option of future genetic reproduction. FP technologies have been developed in the cancer context because infertility is one of the long-term side-effects of many cancers or cancer therapies. Many FP technologies are still experimental, but some technologies are (...) becoming available to healthy women who wish to guard against age-related infertility. Although FP technologies are expanding women’s reproductive options and benefitting some women by satisfying their desires for genetically-related children, these technologies pose numerous physical, emotional and financial risks to women. I maintain that a feminist examination of choice is necessary for the ethical provision of FP technologies within patriarchal contexts. My analysis begins by demarcating two oppressive social biases from one another: namely pronatalism and biologism. I argue that each of these biases can unduly influence women’s reproductive choices about FP technologies. I then consider how these biases might be identified and challenged in the FP decision-making context. I outline an ethical process of informed choice that is equipped to protect patient autonomy when such autonomy is threatened by these biases. I then consider whether the choice to use FP should be available to both women within and without the cancer contexts. I argue that both disease-related FP and age-related FP can be morally permissible. Finally, I consider whether there should be an upper age limit on women’s access to their stored reproductive materials. I argue that age can be morally relevant to reproduction and thus age limits on access to assisted reproduction are morally permissible. I conclude by suggesting how feminist insights might inform policies on FP technologies and related assisted reproductive technologies. In sum, my dissertation shows that a feminist analysis of choices about FP is essential for ensuring the ethical provision of FP technologies. (shrink)

The goal of this dissertation is to contribute to the epistemology of science by addressing a set of related questions arising from current discussions in the philosophy and science of climate change: (1) Given the imperfection of computer models, how do they provide information about large and complex target systems? (2) What is the relationship between consilient reasoning and robust evidential support in the production of scientific knowledge? (3) Does taking the mean of a set of model outputs provide epistemic (...) advantages over using the output of a single ‘best model’? Synthesizing research in philosophy and science, the thesis analyzes connections among consilient inductions, robustness analysis, and the aggregation of various sources of evidence, including computer simulations, by investigating case studies of climate change that exemplify the strength of consilient reasoning and the security of robust evidential support. It also explains the rationale and epistemic conditions for improving estimates by averaging multiple estimates, comparing a simple case of averaging estimates to practices in multi-model ensemble studies. I argue: (A) the concepts of consilience and robustness account for the strength and security of inferences that rely on imperfect computer modelling methods, (B) consilient reasoning is conducive to attaining robust evidential support, and (C) an analogy can explain why averaging the outputs of multiple models can improve estimates of a target system, given that conditions of model independence, skill and unequal weighting are taken into account.

This thesis is a contribution to the ethical justification for clinical research with children. A research subject’s participation in a trial is usually justified, in part, by informed consent. Informed consent helps to uphold the moral principle of respect for persons. But children’s limited ability to make informed choices gives rise to a problem. It is unclear what, if anything, justifies their participation in research. Some research ethicists propose to resolve this problem by appealing to social utility, proxy consent, arguments (...) explaining why it is permissible to expose children to some harm, and an argument concerning the appropriate balance between research harms and benefits. I argue that each of these is a necessary part of the justification for research with children, but that the argument concerning harms and benefits is under-developed. It relies on the concept of minimal risk, but minimal risk is inadequately justified. I propose an interpretation of minimal risk. I defend the idea that minimal risk should be interpreted according to the risks of daily life. I reject the most prominent defense of daily life, which claims that daily risks are morally relevant because they replace, rather than add to, the risks a child would ordinarily face. Instead, I propose that these risks are part of a reasonable trade-off between personal safety and our ability to pursue meaningful lives. I then examine whose daily life should be captured in the concept of minimal risk. I reject arguments that minimal risk should refer to healthy children or the subjects of the research and propose instead that the referent should be children who are not unduly burdened by their lives. I argue that children are not unduly burdened when they fare well and defend the idea that children fare well when they possess sufficiently high degrees of the substantive goods of childhood. I conclude by analyzing a controversial case study using my interpretation of minimal risk. I draw on this case to argue that my interpretation offers clear guidance for research ethics review and contributes to a determination that is more plausible than its rivals. (shrink)

Species are central to biology, but there is currently no agreement on what the adequate species concept should be, and many have adopted a pluralist stance: different species concepts will be required for different purposes. This thesis is a multidimensional analysis of species pluralism. First I explicate how pluralism differs monism and relativism. I then consider the history of species pluralism. I argue that we must re-frame the species problem, and that re-evaluating Aristotle's role in the histories of systematics can (...) shed light on pluralism. Next I consider different forms of pluralism: evolutionary and extra-evolutionary species pluralism, which differ in their stance on evolutionary theory. I show that pluralism is more than a debate about the species category, but a debate about which concepts are legitimate and a claim about how they interact with one another. Following that, I consider what sort of ontology is required for different forms of species pluralism. I argue that pluralists who deny the unity of biology will require a further plurality of frameworks, while those that ground their pluralism in evolution need only one framework. Finally, I consider what pluralism means for biological practice. I argue that species concepts are tools, and reflect on how pluralism can illuminate the way systematists approach the discovery of new species of yeast. Pluralism can make sense of the way species concepts are used, and can be developed to aid researchers in thinking about how to use the right tools for the right jobs. (shrink)

Thomas Bradwardine (d. 1349) was an English philosopher, logician, and theologian of some note; but though recent scholarship has revived an interest in much of his work, little attention has been paid to an early treatise he wrote on the topic of future contingents, entitled De futuris contingentibus. In this thesis I aim to address this deficit, arguing in particular that the treatise makes original use of the divine power distinction to resolve the apparent conflict between God’s foreknowledge on the (...) one hand, and human free will on the other. Bradwardine argues that God’s foreknowledge operates in accord with God’s ordained power, and so relative to God’s ordained power, our actions are indeed compelled; however, because of Bradwardine’s appeal to the distinction in power, he is able to maintain that our actions remain free relative to God’s absolute power, and are thus free, absolutely speaking. This solution is, I argue, unique to Bradwardine, although it seems to be abandoned in his later writing. Bradwardine’s approach to the problem is heavily influenced by three figures in particular — Boethius, Anselm of Canterbury, and John Duns Scotus — each of whose solutions I discuss in some detail. Furthermore, Bradwardine explicitly places his own solution in opposition to that of William Ockham, and so I give substantial attention to examining Ockham’s position. But while I agree with Bradwardine’s assessment that Ockham’s position undermines God’s foreknowledge in ways that should be untenable to someone of 14th-century Christian commitments, I argue that Bradwardine’s solution amounts to an equally untenable determinism. An appendix contains excerpts from my own English translation of the De futuris contingentibus (the first into any modern language), in parallel with the original Latin. (shrink)

A central component to scientific practice is the construction and use of scientific models. Scientists believe that the success of a model justifies making claims that go beyond the model itself. However, philosophical analysis of models suggests that drawing inferences about the world from successful models is more complex. In this dissertation I develop a framework that can help disentangle the related strands of evaluation of model success, model extendibility, and the ability to draw ampliative inferences about the world from (...) models. I present and critically assess two leading accounts of model assessment, arguing that neither is sufficient to provide a complete understanding of model evaluation. I introduce a more powerful framework incorporating elements of the two views, which can help answer these three questions: What is the target of evaluation in model assessment? How does that evaluation proceed? What licenses us in making inferences about the real world, based on the evaluation of our models as successful? The framework identifies two distinct targets of model evaluation: representational similarity between the model and target system, and the adequacy of the model as a tool to answer questions. Both assessments must be relativized to a purpose, of which there are three general kinds: descriptive, predictive, and explanatory. These purposes differ in the way they inform the similarity relation, which is relevant for the similarity assessment, and the output they produce, which is relevant for the adequacy assessment. Any model can be assessed relative to any purpose, however a model encodes certain decisions made during the model’s construction, which impact its ability to be applied to a new purpose or new domain. My framework shows that extending a model, and drawing inferences from it, depends on its representational similarity. I apply this framework to several examples taken from astrophysics showing in detail how it can help illuminate the structure of the models, as well as make the justification for inferences made from them clear. The final chapter is a detailed analysis of a contemporary debate surrounding the use of models in astrophysics, between proponents of MOND and the standard ΛCDM model. (shrink)

I will argue that the scientific investigation of philosophical intuition ('experimental philosophy') is of philosophical interest. I will defend the significance of experimental philosophy against two important types of objection. I will term the first objection 'eliminativism' about intuitions: roughly, it is the claim that philosophical methodology does not in fact rely on intuition, and thus experimental philosophy's investigation is ill-conceived—in the words of one such opponent, 'a big mistake.' I will then consider a second objection, the 'expertise' defence. The (...) expertise defence argues that the expert intuitions of professional philosophers are distinct, and to be preferred to those of the 'folk.' Against the eliminativists, I will argue that an ineliminable mental component remains that can be subject of fruitful empirical investigation. Against the expertise defence I will argue that, at least in the context of philosophy of language, expertise is itself a potential source of bias. Since expertise is domain-specific, however, a general rebuttal will not be given. I will conclude that experimental philosophy has much to contribute. (shrink)

This dissertation is a collection of essays exploring the role of metaphor in Aristotle’s scientific method. Aristotle often appeals to metaphors in his scientific practice; but in the Posterior Analytics, he suggests that their use is inimical to science. Why, then, does he use them in natural science? And what does his use of metaphor in science reveal about the nature of his scientific investigations? I approach these questions by investigating the epistemic status of metaphor in Aristotelian science. In the (...) first essay, I defend an interpretation of metaphor as a type of heuristic reasoning: I claim that Aristotle uses metaphor to express conditions an explanation in natural science must meet if it is to explain regular, ordered change. These conditions specify the kinds of causes—particularly unmoved efficient causes—which the inquirer into nature is seeking. In the second essay, I look to Aristotle’s use of certain endoxa or common beliefs as explanatory principles in science, and show that his use of these principles is similar to his use of metaphor. In the final essay, I present a historical study of the analogy of art and nature, and I suggest that by looking to how the Greeks understood the role of inquiry in the arts, we can shed some light on Aristotle’s views concerning the method of inquiry he thinks the natural scientist should adopt.

In this dissertation, I defend the view that natural languages are concrete biopsychological phenomena to be studied empirically. In Section One, I begin with an historical explanation. Some analytic philosophers, I argue, misapply formal logic as an analysis of natural language, when it was in fact originally developed as an alternative to natural language, employed for scientific purposes., quasi-mathematical philosophies of language, I argue, are partially a result of this misunderstanding. I respond to Jerrold Katz’ argument that a proper understanding (...) of analytic truth requires this quasi-mathematical philosophy of language through a model-theoretical analysis of analytic truth in modal and intuitionist logics. In Section Two, I offer a positive argument for a biopsychological philosophy of language. While Chomsky and others have emphasized the metaphysical basis of natural languages in psychological representations, I further contribute to understanding by emphasizing the basis of natural language in psychological representations of relevant properties of a specifically constrained biological implementation base. I defend this ontological perspective through a thorough engagement with the subfield of linguistic phonology and its important relations to physiological articulation and perception, along with an analysis of crucial interface relations among phonology, morphology and syntax. In the final section, I engage with the objections to this biopsychological philosophy of language stemming from concerns related to linguistic normativity and communication. If natural language is based metaphysically in the biopsychological representations of individuals, there are apparent paradoxes in the notion of public rules for language use, and in the notion of shared content for the purpose of communication. Drawing on David Forrest Wallace’s pragmatic conception of linguistic prescription, together with analogies from anti-realist metaethical systems, I defend the intelligibility of public linguistics norms without the need for abstract ontological commitment. Drawing on Ray Jackendoff’s internalist semantic and metasemantic analysese, together with Burtrand Russell’s analogy argument on other minds, I also defend intelligibility of linguistic communication equally without need for abstract ontological commitment.

The past decade or so has witnessed an increase in the number of philosophical discussions about emergence and reduction in science. However, many of these discussions (though not all) remain too abstract and theoretical, and are wanting with respect to concrete examples taken from the sciences. This dissertation studies the topics of reduction and emergence in the context of a case study. I focus on the case of chemistry and investigate how emergentism can help us secure the autonomy of this (...) discipline in relation to the underlying microphysics. I develop an account of emergence (called functional emergence) that is, I argue, capable of answering the question of why we have chemistry instead of just applied quantum mechanics. I argue that functionally emergent properties in chemistry -- properties that are defined by their behaviour, not by some shared microphysical constituent -- can help us defend the autonomy of chemistry; they allow for the existence of sui generis chemical regularities, which can be used in sui generis chemical explanations. Functional emergence generates difficulties for some accounts of inter-theoretic reduction, but unlike other theories of emergence it is compatible with weaker forms of reductionism. (shrink)

The purpose of this dissertation is to contribute to our understanding of scientific theory pursuit by providing a detailed case study on the development of early quantum theory, from roughly 1900 to 1916. I first elaborate on why this case should be considered an instance of piecemeal pursuit by presenting the historical quantum conjectures that were being used in different contexts. These conjectures gave varied interpretations of quantization. By comparing these conjectures, I identify a general quantum postulate that captures the (...) underlying assumption common to all the cases. I argue that it is possible to consider a general postulate about quantization even when its proper application is ambiguous in a given context, and that the postulate can be separated from different elements of the framework being used to investigate it. I show that the quantum postulate can be deemed promising by analysing the support it gains using a Bayesian framework. I first defend the use of such a framework by considering the purported inconsistencies in Planck's introduction of his quantum conjecture and how we should handle these. I then explicate two cases of support for the postulate. First, I show how we can use a particular solution to the Bayesian problem of old evidence to interpret the support the quantum postulate received by accounting for phenomena that had no previous explanation. Finally, I show that the quantum postulate is also supported by a unification argument, where unification is interpreted as informational relevance between the different domains of inquiry. (shrink)

This dissertation investigates the origin, intellectual development and use of a semantic variant of the idea of logical space found implicitly in Kant and explicitly in early Wittgenstein and van Fraassen. It elucidates the idea of logical space as the idea of images or pictures representative of reality organized into a logico-mathematical structure circumscribing a form of all possible worlds. Its main claim is that application of these images or pictures to reality is through a certain conception of self. The (...) first chapter presents a novel interpretation of Kant’s semantic theory of schemata in the Critique of Pure Reason, showing that a structure of the imagination induced by the transcendental self informs an implicit idea of logical space. The second chapter offers an intellectual history of the idea through developments in the organization of images introduced by Helmholtz and Hertz. The third chapter reveals early Wittgenstein’s idea of logical space to be his notion of the self, demonstrating how this serves to unify propositions of the Tractatus Logico-Philosophicus concerning solipsism, realism, ethics, aesthetics and mysticism with those pertaining to the picture theory of meaning. The fourth chapter provides a historical overview of the development of van Fraassen’s empiricism in relation to his adaptation of logical space, and evaluates his recent proposal in Scientific Representation: Paradoxes of Perspective that the problem of coordination in the semantic view of theories is dissolved through self-location in logical space. After identifying a number of problems this proposal creates for his empiricism, a brief suggestion is made about how van Fraassen might improve upon his conception of logical space, and how an empiricist view of scientific representation might be understood as a result.

A pervasive interpretation among Husserl scholars is that his transcendental idealism inevitably leads to some form of solipsism. The aim of this dissertation is to defend Husserl against this charge. First, I argue that Husserl’s transcendental idealism is not a metaphysical theory. Transcendental phenomenology brackets all metaphysical presuppositions and argues from experience to the conditions of the possibility of experience. Husserl’s transcendental idealism should therefore be interpreted as a transcendental theory of knowledge. Second, it follows from the above characterization of (...) Husserl’s transcendental idealism that the responses Husserl gives to the problem of solipsism are in no way meant to prove the existence in-itself of an external world or the existence in-themselves of other transcendental egos. The purpose of Husserl’s engagement with the problem of solipsism is to explain how it is that transcendental phenomenology can account for the constitution of both the Objectivity of the world of experience and other psycho-physical subjects. The result is a set of transcendental arguments that explain the necessary conditions of the cognition of a shared external world and of other persons. I conclude with Husserl that the solipsism is a transcendental illusion, and that Husserl’s transcendental idealism does not lead to a problematic solipsism. Through a careful study of Husserl’s Nachlass, with particular attention paid to Ideas I, Formal and Transcendental Logic, and Cartesian Meditations, I lay the framework for a transcendental-epistemological interpretation of Husserl’s idealism. Applying this interpretive strategy to Husserl’s discussions of the problem of solipsism and intersubjective monadology, I argue that, for Husserl, empathy is the condition of the experience of other subjects, but that it does not allow us to experience the mental-lives of other transcendental egos.

Part 1 of the thesis questions the traditional relation model of intentionality. After fixing reference on the target phenomenon, intentionality, and explaining my interest in it, I ask what sorts of things intentionality might be a relation to. I consider ordinary objects, properties, propositions and hybrid views, and conclude all make the intentional relation appear rather mysterious. From there, I move on to examine the relation view’s most prominent proponents, the tracking theorists—pointing out some challenges such views face, and concluding (...) that it might be worthwhile looking into alternatives to the relation view. Part 2 asks whether the newly emerging phenomenal intentionality movement can provide a viable alternative to the relation model of intentionality. After focusing on a specific kind of phenomenal intentionality theory—something I call modificationism—I examine three such accounts. From there I go on to discuss some common complaints/challenges these kinds of views face, and consider how they might be addressed within the modificationist framework. In Part 3, I address what I call the problem of cognitive contact: how do our contentful mental states manage to make cognitive contact with the ordinary objects (e.g. tables and chairs) that they appear to. The problem is particularly acute for any version of phenomenal intentionality that denies the relation view, and has been given very little attention in the literature. I consider how a modificationist might address this problem, and conclude that though some avenues appear promising, there is nevertheless a great deal of work to be done if modificationism, and phenomenal intentionality theory, is to overcome this problem.

This dissertation examines representationalism about sensory phenomenology—the claim that for a sensory experience to have a particular phenomenal character is a matter of it having a particular representational content. I focus on a particular issue that is central to representationalism: whether reductive versions of the theory should be internalist or externalist. My primary goals are to demonstrate that externalist representationalism fails to provide a reductive explanation for phenomenal qualities, and to present a reductive internalist version of representationalism that utilizes the (...) empirical framework of psychophysics and neuroscience to develop a philosophical theory of content. The bulk of the project is an attempt to provide the outlines of what such an empirically-based representationalist theory would look like. In chapter 2, I argue that reductive externalist representationalism fails because it is vulnerable to the problem of bad structural correlation: the mismatch between the structure of phenomenal qualities and the structure of physical properties “tracked” by our sensory systems with which phenomenal qualities are identified. In chapter 3, I develop the outlines of a reductive internalist version of representationalism that characterizes phenomenal qualities as modes of presentation of sensory representations that can be reductively characterized in terms of a location in a psychophysically-defined quality space, which can in turn be given a neurophysiological interpretation. In addition, I argue that the neural mechanisms responsible for the representation of spatial locations and visual objects serve a referential role in sensory psychosemantics that grounds the intentionality of sensory states. In chapter 5 I provide a detailed account of the representation of spatial locations in sensory experience, and in chapter 6 I examine the “binding problem”, demonstrating how object-based sensory representations function to demonstratively pick out sensory individuals without explicitly representing any of their features. I describe the resulting view as methodological representationalism: an attempt to demonstrate how a particular philosophical theory of sensory phenomenology can be integrated into the empirical framework of cognitive science, and thereby provide an explanatory psychosemantic framework for sensory phenomenology that is valuable to both philosophers and cognitive scientists.

Scientific explanation is an important goal of scientific practise. Philosophers have proposed a striking diversity of seemingly incompatible accounts of explanation, from deductive-nomological to statistical relevance, unification, pragmatic, causal-mechanical, mechanistic, causal intervention, asymptotic, and model-based accounts. In this dissertation I apply two novel methods to reexamine our evidence about scientific explanation in practise and thereby address the fragmentation of philosophical accounts. I start by collecting a data set of 781 articles from one year of the journal Science. Using automated text (...) mining techniques I measure the frequency and distribution of several groups of philosophically interesting words, such as "explain", "cause", "evidence", "theory", "law", "mechanism", and "model". I show that "explain" words are much more common in scientific writing than in other genres, occurring in roughly half of all articles, and that their use is very often qualified or negated. These results about the use of words complement traditional conceptual analysis. Next I use random samples from the data set to develop a large number of small case studies across a wide range of scientific disciplines. I use a sample of "explain" sentences to develop and defend a new general philosophical account of scientific explanation, and then test my account against a larger set of randomly sampled sentences and abstracts. Five coarse categories can classify the explanans and explananda of my cases: data, entities, kinds, models, and theories. The pair of the categories of the explanans and explanandum indicates the "form" of an explanation. The explain-relation supports counterfactual reasoning about the dependence of qualities of the explanandum on qualities of the explanans. But for each form there is a different "core relation" between explanans and explanandum that supports the explain-relation. Causation, modelling, and argument are the core relations for different forms of scientific explanation between different categories of explanans and explananda. This flexibility allows me to resolve some of the fragmentation in the philosophical literature. I provide empirical evidence to show that my general philosophical account successfully describes a wide range of scientific practise across a large number of scientific disciplines. (shrink)

Philipp Frank––physicist, philosopher, and early member of the Vienna Circle––is often neglected in retrospective accounts of twentieth century philosophy of science, despite renewed interest in the work of the Vienna Circle. In this thesis, I argue that this neglect is unwarranted. Appealing to a variety of philosophical and historical sources, I trace the development of Frank’s philosophical thought and, in so doing highlight the roles played by history, sociology, values, and pragmatism in his philosophy of science. Turning to contemporary literature, (...) I then argue that Frank’s work should be understood as an early instance of what is now called “socially engaged philosophy of science.” This understanding is explored through a careful consideration of his work on education, where previous work on history, sociology, values, and pragmatism is applied to an important, real-world problem. This socially engaged reading of Frank extends beyond pragmatic issues of theory application, because as I show, Frank used sociology to argue for the meaningfulness of metaphysical claims. However, Frank’s account of meaning may seem to be problematic since it heavily relies on Percy Bridgman’s operationalism. So, I outline the problems associated with Bridgman’s account of operationalism and show that Frank’s view does not fall prey to the same criticisms. After these objections are addressed, Frank’s work is contextualized in the broader debate about value-free science, where I argue that Frank did not endorse the value-free ideal. As a result of these findings, we will not only have a clearer picture of Frank’s philosophical contributions, but also a better understanding of how the philosophy of science can better engage important social issues.

The three integrated articles of this dissertation are concerned with the epistemic status of moral intuitions. The first article argues in favour of moderate moral intuitionism, the view that while any successful moral epistemology must be intuitionist to at least some extent, it must also take intuitions to be fallible. This is accomplished by synthesizing work by Robert Audi and George Bealer into a view of moral intuitions which is capable of overcoming some major contemporary objections against intuitionism, particularly from (...) Sharon Street and Peter Singer. The next article raises a more powerful objection to intuitionism, applying feminist ethics and moral epistemology to suggest that powerful social forces impair our ability to distinguish mistaken intuitions from reliable ones. This objection is addressed with an argument, based on work by Michele Moody-Adams and Cheshire Calhoun, to the effect that the possibility of moral knowledge and resultant responsibility allow us to retain the capacity for making this important distinction between intuitions. Nevertheless, as George Sher argues, there is still reason to think that the intuitions we rely on to shape and justify our moral beliefs contains important mistakes which negatively impact the reliability of our resulting moral judgements. This major problem, that of distinguishing helpful from harmful moral intuitions, is the topic of the third article. Henry Sidgwick attempted to develop a decision procedure for this purpose in The Methods of Ethics, positing four major criteria, the fulfilment of which would confer the highest possible level of certainty on an intuition. Sidgwick's four tests are evaluated primarily with reference to contemporary feminist scholarship, and though they constitute a promising start to a rigorous intuitionist moral epistemology, they are also wanting in a number of ways. The article improves the epistemic status of Sidgwick's tests with a hybrid Sidgwickian-feminist theory, reinterpreting his tests as values to be respected but which allow flexibility and even tension. While this approach may not be able to confer the same level of certainty as Sidgwick's, it is more respectful of the complexities and nuances of a more reliable moral epistemology. (shrink)

My goal in this dissertation is to articulate an Arendtian conception of feminist agency, that is, agency that aims at resistance from within oppressive situations. There is a tendency in feminist literature to depict women in the global south as if they are passive victims of their oppression, with no opportunities to resist. This tendency is replicated in feminist responses to transnational contract pregnancy, the practice in which people travel across national borders to hire a woman to gestate an embryo. (...) I argue that the feminist literature on contract pregnancy is polarized and unable to resolve the problematic trend of ignoring women’s agency. On one side, some feminists argue that contract pregnancy can enhance women’s agency by challenging oppressive norms or by expanding women’s choices. On the other side, some feminists argue that contract pregnancy obstructs women’s agency by perpetuating oppressive norms and by inappropriately commodifying women’s reproductive labor. To depolarize the debate, I propose a conception of feminist agency that allows for women to exercise agency against aspects of their oppression. Drawing from Hannah Arendt, I contend that feminist agency is a relational enterprise by which the agent comes to know herself, and by which others come to know her. Moreover, feminist agency necessarily contains an element of resistance. The central feature feminist agency is drawn from Arendt’s conception of thinking, which refers to critical reflection that enables people to reject certain beliefs and commitments. I suggest a contract pregnant woman may be motivated to think by lived contradictions within her experience. In other words, the inability of dominantly held social beliefs to explain the woman’s experiences can prompt her to think. The rejection of oppressive social norms allows the contract pregnant woman to understand contract pregnancy in a new way, and can encourage individual acts of resistance to oppression. Thus, feminist agency is able to appreciate how women in oppressed circumstances may resist aspects of their oppression. In addition to using Arendt to resolve a problematic tendency in feminist theory, I also argue that feminist theory helps to open up Arendt’s work to new application, specifically with respect to reproductive justice.

The aim of this dissertation is to outline and defend the view here dubbed “anti-foundational categorical structuralism” (henceforth AFCS). The program put forth is intended to provide an answer the question “what is mathematics?”. The answer here on offer adopts the structuralist view of mathematics, in that mathematics is taken to be “the science of structure” expressed in the language of category theory, which is argued to accurately capture the notion of a “structural property”. In characterizing mathematical theorems as both (...) conditional and schematic in form, the program is forced to give up claims to securing the truth of its theorems, as well as give up a semantics which involves reference to special, distinguished “mathematical objects”, or which involves quantification over a fixed domain of such objects. One who wishes—contrary to the AFCS view—to inject mathematics with a “standard” semantics, and to provide a secure epistemic foundation for the theorems of mathematics, in short, one who wishes for a foundation for mathematics, will surely find this view lacking. However, I argue that a satisfactory development of the structuralist view, couched in the language of category theory, accurately represents our best understanding of the content of mathematical theorems and thereby obviates the need for any foundational program.

It is often thought that Kant abandoned his argument for the justification of morality in the Groundwork of the Metaphysics of Morals for a radically different argument in the Critique of Practical Reason. In the Groundwork, Kant appears to try to justify our commitment to the moral law on the basis of our freedom, but in the Critique, he tries to justify that commitment on the basis of what he calls the fact of reason. I assess and reject influential interpretations (...) of both arguments as being philosophically unsound, and I propose, what I take to be, a novel and promising account of the fact of reason.

Aristotle’s Naïve Somatism is a re-interpretation of Aristotle’s cognitive psychology in light of certain presuppositions he holds about the living animal body. The living animal body is presumed to be sensitive, and Aristotle grounds his account of cognition in a rudimentary proprioceptive awareness one has of her body. With that presupposed metaphysics under our belts, we are in a position to see that Aristotle in de Anima (cognition chapters at least) has a di erent explanatory aim in view than that (...) which the literature generally imputes to him. He is not explicating what we would call the “mental”—the private, inner realm which some take to be of a di erent kind than the physical—as most take him to be. His explanandum is content acquisition; the explanans is showing how the body becomes like various aspects of objects. Although he famously describes the mind (nous) as unmixed with the body, he is guided by functional constrains—nous cannot be limited or qualified if it is to potentially think all things. Thus, his inquiry into cognition is philosophically limited from a contemporary perspective. Aristotle is not doing philosophy of mind, for he doesn’t seem to find the “mental” philosophically perplexing. (shrink)

In chapter one I firstly critique some contemporary family-resemblance approaches to the category woman, and claim that they do not take sufficient account of dis-semblance, that is, resemblances that people have in common with members of the contrast category man. Second, I analyze how the concept of woman is semantically contestable: resemblance/dissemblance structures give rise to vagueness and to borderline cases. Borderline cases can either be included in the category or excluded from it. The factors which incline parties in a (...) dispute about membership to include or exclude depend on metaphysical, ethical, or political background assumptions. In chapter two, I begin by considering the harms suffered by transgender persons through “misgendering”, the deployment of gender terms which inflict psychological harms upon transgender persons, place them in situations of injustice, or diminish their self-respect. Such deployments are morally contestable: they can be challenged on ethical grounds. Several characterisations of the term ‘woman’ proposed in the feminist literature are critiqued from this perspective. In chapter three, I elaborate a broadly liberal approach to gender pluralism. The approach involves: i) the public toleration of gender practices and beliefs which contest prevalent gender norms; and ii) state-gender neutrality. Public toleration allows gender non-conforming practices and beliefs within public space. State gender-neutrality consists mainly in the removal from law and government policy of provisions which assume compliance with prevalent conceptions of gender. (shrink)

Severe brain injury is a leading cause of death and disability. Following severe brain injury diagnosis is difficult and errors frequently occur. Recent findings in clinical neuroscience may offer a solution. Neuroimaging has been used to detect preserved cognitive function and awareness in some patients clinically diagnosed as being in a vegetative state. Remarkably, neuroimaging has also been used to communicate with some vegetative patients through a series of yes/no questions. Some have speculated that, one day, this method may allow (...) severely brain-injured patients to make medical decisions. Yet, skepticism is rife, due in part to the inherent difficulty of assessing decision-making capacity through neuroimaging communication. In this thesis, I provide the first systematic analysis of this problem. I present and defend a strategy for assessing decision-making capacity in brain-injured patients who can only communicate through neuroimaging. (shrink)

This dissertation addresses the following questions: How should epistemologists conceptualize testimony? What do people use testimony to do? And why does ‘what people do’ with testimony matter epistemically? In response to these questions I both define and characterize testimony. While doing so I argue for the following answers, given here very briefly: What do people do when they testify? They tell each other things and avow that those things are true, offering their statements to others as reasons to believe. More (...) importantly, they interact with each other in order to negotiate about significance. Why do these activities matter epistemically? Because by engaging in them people generate understanding, as well as knowledge, that no one involved may have had prior to negotiation. Not only that, but they generate collective hermeneutic resources—conceptual tools with which to interpret and understand. In so doing, they not only learn, they create significance and (re)construct social worlds, living together as epistemic, moral, and political agents. So, how should epistemologists conceptualize testimony? They should treat it as a particular speech act that most often occurs as part of a testimonial exchange—an interactive, interpretive, dialogical activity that people use in order to negotiate about significance and generate understanding. This characterization of testimony is an important contribution because it: reveals some of the distinctively social aspects of testimonial knowledge and understanding; suggests better answers to epistemic questions about testimony than those based on typical characterizations in the literature; leads discussion on the topic in a number of new directions; and it lays a foundation for an ethics of testimony that cannot be separated from epistemic concerns. Neither can those concerns be separated from social, moral, and political considerations. The position thus pushes epistemologists to investigate the intertwining of epistemic, moral, and political agency. (shrink)

In the first half of this dissertation, I develop a heuristic methodology for analyzing scientific solutions to the problem of underdetermination. Heuristics are rough-and-ready procedures used by scientists to construct models, design experiments, interpret evidence, etc. But as powerful as they are, heuristics are also error-prone. Therefore, I argue that they key to prudently using a heuristic is the articulation of meta-heuristics---guidelines to the kinds of problems for which a heuristic is well- or ill-suited. Given that heuristics will introduce certain (...) errors into our scientific investigations, I emphasize the importance of a particular category of meta-heuristics involving the search for robust evidence. Robustness is understood to be the epistemic virtue bestowed by agreement amongst multiple modes of determination. The more modes we have at our disposal, and the more these confirm the same result, the more confident can we be that a result is not a mere artifact of some heuristic simplification. Through an analysis of case-studies in the philosophy of biology and clinical trials, I develop a principled method for modeling and evaluating heuristics and robustness claims in a qualitative problem space. The second half of the dissertation deploys the heuristic methodology to address ethical and epistemological issues in the science of clinical trials. To that end, I develop a network model for the problem space of clinical research, capable of representing the various kinds of experiments, epistemic relationships, and ethical justifications intrinsic to the domain. I then apply this model to ongoing research with the antibacterial agent, moxifloxacin, for the treatment of tuberculosis, tracking its development from initially successful and promising in vitro and animal studies to its disappointing and discordant performance across five human efficacy trials. Given this failure to find a robust result with moxifloxacin across animal and human studies, what should researchers now do? While my final analysis of this case does not definitively answer that question, I demonstrate how my methodology, unlike a statistical meta-analysis, helps to clarify the directions for further research.

This thesis makes the issue of reconciling the existence of thermodynamically irreversible processes with underlying reversible dynamics clear, so as to help explain what philosophers mean when they say that an aim of nonequilibrium statistical mechanics is to underpin aspects of thermodynamics. Many of the leading attempts to reconcile the existence of thermodynamically irreversible processes with underlying reversible dynamics proceed by way of discussions that attempt to underpin the following qualitative facts: (i) that isolated macroscopic systems that begin away from (...) equilibrium spontaneously approach equilibrium, and (ii) that they remain in equilibrium for incredibly long periods of time. These attempts standardly appeal to phase space considerations and notions of typicality. This thesis considers and evaluates leading typicality accounts, and, in particular, highlights their limitations. Importantly, these accounts do not underpin a large and important set of facts. They do not, for example, underpin facts about the rates in which systems approach equilibrium, or facts about the kinds of states they pass through on their way to equilibrium, or facts about fluctuation phenomena. To remedy these and other shortfalls, this thesis promotes an alternative, and arguably more important, line of research: understanding and accounting for the success of the techniques and equations physicists use to model the behaviour of systems that begin away from equilibrium. Accounting for their success would help underpin not just the qualitative facts the literature has focused on, but also many of the important quantitative facts that typicality accounts cannot. This thesis also takes steps in this promising direction. It outlines and examines a technique commonly used to model the behaviour of an interesting and important kind of system: a Brownian particle that's been introduced to an isolated homogeneous fluid at equilibrium. As this thesis highlights, the technique returns a wealth of quantitative and qualitative information. This thesis also attempts to account for the success of the model and technique, by identifying and grounding the technique's key assumptions. (shrink)

This dissertation consists of three independent papers, each defending the Higher-Order Thought (HOT) Theory of Consciousness against a different objection. First the HOT theory is defended against the Theory of Mind (TOM) Objection. Since the HOT theory requires that a subject be able to represent mental states in thought in order to have mental states that are conscious, objectors argue from empirical evidence that few creatures pass TOM tests to the conclusion that few creatures must be capable of having conscious (...) mental states according to the HOT theory. The counter-intuitiveness of this claim is then taken as reason for rejecting the HOT theory. I argue that this objection is based on a false assumption - that the requirements of successful TOM test performance parallel the requirements outlined by the HOT theory. Since this assumption is false, we can reject the objection. In the second paper, I defend the HOT theory against the Phenomenal Character Argument. Objectors argue that the HOT theory must be rejected because it incorrectly characterizes the phenomenal character affiliated with basic state consciousness as necessarily involving a consciousness of the fact that one has a particular mental state. I argue that the theory cannot provide this characterization of phenomenal character because the theory cannot say that someone becomes conscious of what her unconscious HOTs represent. Since the objection rests on an incorrect interpretation of the theory, we can reject the objection. In the final paper, I defend the HOT theory against the Misrepresentation Objection. Here objectors accuse the HOT theory of presenting necessary and sufficient conditions for conscious states that turn out to be incompatible in empty HOT cases (cases wherein one’s HOT misrepresents the states one is instantiating). I argue that the conditions are actually each part of separate explanations of separate sorts of consciousness, that neither of the separate explanations has internally incompatible conditions, and hence that the objection is based on an equivocation on two senses of the phrase ‘conscious state’. Since the objection is based on this error, we can reject the objection. (shrink)

Since the 1980’s, surrogacy has become a popular reproductive alternative for individuals experiencing infertility. The ethical and legal analyses of surrogacy have been rich and varied. Some bioethicists have charged the commercial surrogacy industry with the exploitation of global southern women or with the impermissible commodification of children and women’s reproductive capacities. Others have praised the potential for economic empowerment and bodily autonomy that surrogacy may accord to women. However, throughout these explorations of the ethics of surrogacy, comparatively little attention (...) has been paid to the moral status of a crucial actor: the fertility doctor. Without doctors willing to provide prenatal and postnatal care to surrogates and make use of assisted reproductive technologies (ARTs), commercial surrogacy would not take place. Yet, doctors’ involvement in surrogacy is far from morally neutral. In my thesis, I aim to explore what duties doctors have in the context of commercial surrogacy. To do so, I take up the framework of fiduciary obligation. I argue that doctors have fiduciary obligations to surrogates, and that these obligations shape if and when doctors can ethically facilitate surrogacy. My thesis is divided into four chapters. The first defends the view that the doctor-patient relationship is fiduciary in nature. The second chapter extends this view to the realm of commercial surrogacy, arguing that doctors also owe the surrogates they treat fiduciary obligations. The third chapter addresses a challenge posed by my view, namely that surrogacy seems to place doctors in positions where they constantly face conflicts of interest, and are therefore unable to uphold their fiduciary duty of loyalty to surrogates. I address this concern by arguing that conflicts of interest are not inherent in surrogacy, but that surrogacy arrangements must be substantially rethought in order to safeguard the doctor-surrogate fiduciary relationship. The final chapter considers the obligations doctors have to the children they help create through surrogacy and through assisted reproduction more generally. (shrink)

Neuroimaging technology is the most widely used tool to study human cognition. While originally a promising tool for mapping the content of cognitive theories onto the structures of the brain, recently developed tools for the analysis, handling and sharing of data have changed the theoretical landscape of cognitive neuroscience. Even with these advancements philosophical analyses of evidence in neuroimaging remain skeptical of the promise of neuroimaging technology. These views often treat the analysis techniques used to make sense of data produced (...) in a neuroimaging experiment as one, attributing the inferential limitations of analysis pipelines to the technology as a whole. Situated against the neuroscientists own critical assessment of their methods and the limitations of those methods, this skepticism appears based on a misunderstanding of the role data analysis techniques play in neuroimaging research. My project picks up here, examining how data analysis techniques, such as pattern classification analysis, are used to assess the evidential value of neuroimaging data. The project takes the form of three papers. In the first I identify the use of multiple data analysis techniques as an important aspect of the data interpretation process that is overlooked by critics. In the second I develop an account of inferences in neuroimaging research that is sensitive to this use of data analysis techniques, arguing that interpreting neuroimaging data is a process of isolating and explaining a variety of data patterns. In the third I argue that the development and uptake of new techniques for analyzing data must be accompanied by changes in research practices and standards of evidence if they are to promote knowledge generation. My approach to this work is both traditionally philosophical, insofar as it involves reading and analyzing the work of philosophers and neuroscientists, and embedded insofar as most of the research was conducted while engaged in attending lab meetings and participating in the work of those scientists whose work is the object of my research.

This presentation reflects on the fact that the idea of determinism, or fatalism, keeps recurring, in very different contexts, at different times: logical fatalism, theological fatalism, physical determinism, etc. Standing back and looking at this big picture, it voices the suspicion that all these different determinist theses are manifestations of a single, deeper, conceptual trouble.

According to the traditional view, beliefs and desires are mental representations that play particular functional roles. A belief that P is state which represents P and plays the belief-role, while a desire that P is a state which represents that P and plays the desire-role. In this dissertation I argue that the traditional view has trouble accounting for (a) role that belief and desire play in the causal and rational explanation of behaviour and (b) our knowledge of our own conscious, (...) occurrent beliefs and desires. -/- In its place I argue for Pure Attitude Representationalism (PAR), which holds that beliefs and desires are not to be distinguished from one another by their functional role, but instead entirely by their representational content. According to PAR, desires are distinct from beliefs not because they do different things, but because desires represent things as being rewarding. Throughout the three papers that comprise this dissertation I argue that PAR provides a better explanation of (a) and (b). (shrink)
