In the literature over the Ramsey-sentence approach to structural realism, there is often debate over whether structural realists can legitimately restrict the range of the second-order quantifiers, in order to avoid the Newman problem. In this paper, I argue that even if they are allowed to, it won’t help: even if the Ramsey sentence is interpreted using such restricted quantifiers, it is still an implausible candidate to capture a theory’s structural content. To do so, I use the following observation: (...) if a Ramsey sentence did encode a theory’s structural content, then two theories would be structurally equivalent just in case they have logically equivalent Ramsey sentences. I then argue that this criterion for structural equivalence is implausible, even where frame or Henkin semantics are used. (shrink)

The Taming of the True poses a broad challenge to realist views of meaning and truth that have been prominent in recent philosophy. Neil Tennant argues compellingly that every truth is knowable, and that an effective logical system can be based on this principle. He lays the foundations for global semantic anti-realism and extends its consequences from the philosophy of mathematics and logic to the theory of meaning, metaphysics, and epistemology.

Are moral properties intellectually indispensable, and, if so, what consequences does this have for our understanding of their nature, and of our talk and knowledge of them? Are mathematical objects intellectually indispensable, and, if so, what consequences does this have for our understanding of their nature, and of our talk and knowledge of them? What similarities are there, if any, in the answers to the first two questions? Can comparison of the two cases shed light on which answers are most (...) plausible in either case? This chapter – the introduction to the volume Explanation in Ethics and Mathematics – elucidates these questions and sketches their history. (shrink)

An account of how a rational agent should revise beliefs in the light of new evidence.

John McDowell claims that virtuous people recognize moral reasons using a perceptual capacity that doesn't include desire. I show that the phenomena he cites are better explained if desire makes us see considerations favoring its satisfaction as reasons. The salience of moral considerations to the virtuous, like the salience of food to the hungry, exemplifies the emotional and attentional effects of desire. I offer a desire-based account of how we can follow uncodifiable rules of common-sense morality and how some reasons (...) can be silenced in deliberation. I conclude by arguing that animals can be virtuous by having the right desires. (shrink)

Nietzsche takes moral judgments to be false beliefs, and encourages us to pursue subjective nonmoral value arising from our passions. His view that strong and unified passions make one virtuous is mathematically derivable from this subjectivism and a conceptual analysis of virtue, explaining his evaluations of character and the nature of the Overman.

Essays devoted to the work of the late Neil Wilson, Canadian philosopher and contributor to the field of semantic analysis that emerged from the fusion of logic, pragmatism, and ontology. Many of the essays in this volume take their initial inspiration from Wilson's seminal work Substances Without Substrata.

We examine the sense in which logic is a priori, and explain how mathematical theories can be dichotomized non-trivially into analytic and synthetic portions. We argue that Core Logic contains exactly the a-priori-because-analytically-valid deductive principles. We introduce the reader to Core Logic by explaining its relationship to other logical systems, and stating its rules of inference. Important metatheorems about Core Logic are reported, and its important features noted. Core Logic can serve as the basis for a foundational program that could (...) be called Natural Logicism, an exposition of which will build on the (meta)logical ideas explained here. (shrink)

In Thus Spoke Zarathustra, Nietzsche presents passion as constituting human agency. He encountered this Humean view in Schopenhauer, and recognized its explanatory advantages over Platonic and Kantian rationalism. Zarathustra's poetic speeches anticipate and address contemporary objections to the view that passion constitutes agency. "On the Despisers of the Body" explains why understanding the self as constituted by passion provides better explanations of reasoning, value judgment, and the unity of the self than Christine Korsgaard's neo-Kantian view. "On Enjoying and Suffering the (...) Passions" explains why understanding virtues as constituted by passions provides a better explanation of moral phenomenology than John McDowell's rationalism.

Nietzsche and Hume agree that desire drives all human action and practical reasoning. This shared view helps them appreciate continuities between human and animal motivation and sets them against a long tradition of rationalist rivals including Kant and Plato. In responding to Kant, Nietzsche further developed the Humean views that Kant himself was responding to. Kantians like Christine Korsgaard argue that reflective endorsement and rejection of options presented by desire demonstrates reason’s ability to independently drive reasoning and action. In Daybreak (...) 109, Nietzsche provides a simpler Humean explanation: reflective endorsement and rejection involve reflecting on one desire from the viewpoint of another, with desire as the only motivational force. This explains the attentional and hedonic phenomenology of reflective endorsement without ascribing any motivational force to rational processes independent of desire. (shrink)

De Cruz and Levy, in their commentaries on Religion as Make-Believe, present distinct questions that can be addressed by clarifying one core idea. De Cruz asks whether one can rationally assess the mental state of religious credence that I theorize. Levy asks why we should not explain the data on religious “belief” merely by positing factual beliefs with religious contents, which happen to be rationally acquired through testimony. To both, I say that having religious credences is p-irrational: a purposeful departure (...) from rational thought and behavior, where the purpose in question is maintaining a group identity.

Epistemic akrasia can be rational. I consider a lonely pragmatist who believes that her imaginary friend doesn’t exist, and also believes on pragmatic grounds that she should believe in him. She rationally believes that her imaginary friend doesn’t exist, rationally follows various sources of evidence to the view that she should believe in him to end her loneliness, and rationally holds these attitudes simultaneously. Evidentialism suggests that her ambivalent epistemic state is rational, as considerations grounded in the value of truth (...) justify her beliefs. (shrink)

Awarding rights to rivers, forests, and other environmental entities (EEs) is a new and increasingly popular approach to environmental protection. The distinctive feature of such rights of nature (RoN) legislation is that direct duties are owed to the EEs. This paper presents a novel rebuttal of the strongest argument against RoN: the no interest argument. The crux of this argument is that because EEs are not sentient, they cannot possess the kinds of interests necessary to ground direct duties. Therefore, they (...) cannot be legitimate rights-bearers. After considering and rejecting standard responses to this argument, the paper challenges its fundamental assumption: that rights-correlative duties must be grounded in the interests of the rights-bearer. The paper then presents the RoN critic with a dilemma. The critic must either accept that EEs are legitimate rights-bearers, or delegitimise many well-established rights-bearers along with EEs. Either way, the no interest argument loses its force. (shrink)

The religious autobiography of John Henry Newman (1801-1890), in which he discusses his conversion to Roman Catholicism.

This is Part I of a two-part study of the foundations of mathematics through the lenses of (i) apriority and analyticity, and (ii) the resources supplied by Core Logic. Here we explain what is meant by apriority, as the notion applies to knowledge and possibly also to truths in general. We distinguish grounds for knowledge from grounds of truth, in light of our recent work on truthmakers. We then examine the role of apriority in the realism/anti-realism debate. We raise a (...) hitherto unnoticed problem for any Orthodox Realist who attempts to explain the a priori. (shrink)

We are constantly called upon to evaluate the evidential weight of testimony, and to balance its deliverances against our own independent thinking. ‘Intellectual autonomy’ is the virtue that is supposed to be displayed by those who engage in cognition in this domain well. I argue that this is at best a misleading label for the virtue, because virtuous cognition in this domain consists in thinking with others, and intelligently responding to testimony. I argue that the existing label supports an excessively (...) individualistic conception of good thinking, both within and outside philosophy. I propose replacing ‘intellectual autonomy’ with ‘intellectual interdependence’, which properly emphasises the depth of our reliance on one another, without suggesting we ought ever to be epistemically servile. (shrink)

We compare Fregean theorizing about sets with the theorizing of an ontologically non-committal, natural-deduction based, inferentialist. The latter uses free Core logic, and confers meanings on logico-mathematical expressions by means of rules for introducing them in conclusions and eliminating them from major premises. Those expressions (such as the set-abstraction operator) that form singular terms have their rules framed so as to deal with canonical identity statements as their conclusions or major premises. We extend this treatment to pasigraphs as well, in (...) the case of set theory. These are defined expressions (such as ‘subset of’, or ‘power set of’) that are treated as basic in the lingua franca of informal set theory. Employing pasigraphs in accordance with their own natural-deduction rules enables one to ‘atomicize’ rigorous mathematical reasoning. (shrink)

Over the past several decades, psychological essentialism has been an important topic of study, incorporating research from multiple areas of psychology, philosophy and linguistics. At its most basic level, essentialism is the tendency to represent certain concepts in terms of a deeper, unobservable property that is responsible for category membership. Originally, this concept was used to understand people’s reasoning about natural kind concepts, such as TIGER and WATER, but more recently, researchers have identified the emergence of essentialist-like intuitions in a (...) number of other contexts, including people’s representation of concepts like SCIENTIST or CHRISTIAN. This paper develops an account that aims to capture how essentialism may operate across these varied cases. In short, we argue that while there is diversity in the forms essentialism can take, these varied cases reflect the same underlying cognitive structure. (shrink)

This essay argues that there are theoretical benefits to keeping distinct—more pervasively than the literature has done so far—the psychological states of imagining that p versus believing that in-the-story p, when it comes to cognition of fiction and other forms of narrative. Positing both in the minds of a story’s audience helps explain the full range of reactions characteristic of story consumption. This distinction also has interesting conceptual and explanatory dimensions that haven’t been carefully observed, and the two mental state (...) types make distinct contributions to generating emotional responses to stories. Finally, the differences between the mental states illuminate how a given story can be both shared with others and at the same time experienced as personal. (shrink)

Neil E. Williams develops a systematic metaphysics centred on the idea of powers, as a rival to neo-Humeanism, the dominant systematic metaphysics in philosophy today. Williams takes powers to be inherently causal properties and uses them as the foundation of his explanations of causation, persistence, laws, and modality.

On his death in 2007, Richard Rorty was heralded by the New York Times as “one of the world’s most influential contemporary thinkers.” Controversial on the left and the right for his critiques of objectivity and political radicalism, Rorty experienced a renown denied to all but a handful of living philosophers. In this masterly biography, Neil Gross explores the path of Rorty’s thought over the decades in order to trace the intellectual and professional journey that led him to that (...) prominence. The child of a pair of leftist writers who worried that their precocious son “wasn’t rebellious enough,” Rorty enrolled at the University of Chicago at the age of fifteen. There he came under the tutelage of polymath Richard McKeon, whose catholic approach to philosophical systems would profoundly influence Rorty’s own thought. Doctoral work at Yale led to Rorty’s landing a job at Princeton, where his colleagues were primarily analytic philosophers. With a series of publications in the 1960s, Rorty quickly established himself as a strong thinker in that tradition—but by the late 1970s Rorty had eschewed the idea of objective truth altogether, urging philosophers to take a “relaxed attitude” toward the question of logical rigor. Drawing on the pragmatism of John Dewey, he argued that philosophers should instead open themselves up to multiple methods of thought and sources of knowledge—an approach that would culminate in the publication of Philosophy and the Mirror of Nature , one of the most seminal and controversial philosophical works of our time. In clear and compelling fashion, Gross sets that surprising shift in Rorty’s thought in the context of his life and social experiences, revealing the many disparate influences that contribute to the making of knowledge. As much a book about the growth of ideas as it is a biography of a philosopher, Richard Rorty will provide readers with a fresh understanding of both the man and the course of twentieth-century thought.

How far should our realism extend? For many years philosophers of mathematics and philosophers of ethics have worked independently to address the question of how best to understand the entities apparently referred to by mathematical and ethical talk. But the similarities between their endeavours are not often emphasised. This book provides that emphasis. In particular, it focuses on two types of argumentative strategies that have been deployed in both areas. The first—debunking arguments—aims to put pressure on realism by emphasising the (...) seeming redundancy of mathematical or moral entities when it comes to explaining our judgements. In the moral realm this challenge has been made by Gilbert Harman and Sharon Street; in the mathematical realm it is known as the 'Benacerraf-Field' problem. The second strategy—indispensability arguments—aims to provide support for realism by emphasising the seeming intellectual indispensability of mathematical or moral entities, for example when constructing good explanatory theories. This strategy is associated with Quine and Putnam in mathematics and with Nicholas Sturgeon and David Enoch in ethics. Explanation in Ethics and Mathematics addresses these issues through an explicitly comparative methodology which we call the 'companions in illumination' approach. By considering how argumentative strategies in the philosophy of mathematics might apply to the philosophy of ethics, and vice versa, the papers collected here break new ground in both areas. For good measure, two further companions for illumination are also broached: the philosophy of chance and the philosophy of religion. Collectively, these comparisons light up new questions, arguments, and problems of interest to scholars interested in realism in any area. (shrink)

[OPEN ACCESS TARGET ARTICLE WITH COMMENTARIES AND RESPONSE] We develop a new model of how human agency-detection capacities and other socio-cognitive biases are involved in forming religious beliefs. Crucially, we distinguish general religious beliefs (such as *God exists*) from personal religious beliefs that directly refer to the agent holding the belief or to her peripersonal time and space (such as *God appeared to _me_ last night*). On our model, people acquire general religious beliefs mostly from their surrounding culture; however, people (...) use agency-intuitions and other low-level experiences to form personal religious beliefs. We call our model the Interactive Religious Experience Model (IREM). IREM inverts received versions of Hyperactive Agency-Detection Device Theory (HADD Theory): instead of saying that agency-intuitions are major causes of religious belief in general, IREM says that general belief in supernatural agents causes people to seek situations that trigger agency-intuitions and other experiences, since these enable one to form personal beliefs about those agents. In addition to developing this model, we (1) present empirical and conceptual difficulties with received versions of HADD Theory, (2) explain how IREM incorporates philosophical work on indexical belief, (3) relate IREM to existing anthropological and psychological research, and (4) propose future empirical research programs based on IREM.

This paper rebuts criticisms by Hintikka of the author's account of game-theoretic semantics for classical logic. At issue are (i) the role of the axiom of choice in proving the equivalence of the game-theoretic account with the standard truth-theoretic account; (ii) the alleged need for quantification over strategies when providing a game-theoretic semantics; and (iii) the role of Tarski's Convention T. As a result of the ideas marshalled in response to Hintikka, the author puts forward a new conjecture concerning the (...) relationship among truth, meaning and translation. (shrink)

One of the major contributions which Christopher Hookway has made to pragmatist epistemology is a critical exploration of the role that affective dispositions play in inquiry. According to Hookway, a well-functioning rational inquirer must rely upon a set of pre-reflective and affective dispositions which are not themselves fully available to rational evaluation. Despite their pre-reflective nature, on the pragmatist account these affective dispositions provide us with judgments and evaluations which are in many cases more reliable than those provided by explicit (...) rational reflection. -/- This chapter presents and defends Hookway’s account of the epistemic importance of our affective dispositions. The first section presents three roles which affective dispositions play within inquiry. The second section considers the concern that affective dispositions should be considered impositions upon our epistemic agency. In response, Hookway suggests that we must identify with our affective dispositions, and two interpretations of this claim are offered. The third section considers the possibility that the confidence we have in our affective dispositions might be appropriately shaken if we recognize that they are not shared by other inquirers. The chapter concludes by suggesting that Hookway’s position can overcome this worry by developing his notion of critical self-trust in three distinct ways. (shrink)

Data science, and the related field of big data, is an emerging discipline involving the analysis of data to solve problems and develop insights. This rapidly growing domain promises many benefits to both consumers and businesses. However, the use of big data analytics can also introduce many ethical concerns, stemming from, for example, the possible loss of privacy or the harming of a sub-category of the population via a classification algorithm. To help address these potential ethical challenges, this paper maps (...) and describes the main ethical themes that were identified via systematic literature review. It then identifies a possible structure to integrate these themes within a data science project, thus helping to provide some structure in the on-going debate with respect to the possible ethical situations that can arise when using data science analytics.

Given the tremendous proliferation of student plagiarism involving the Internet, the purpose of this study is to determine which theory of ethical reasoning students invoke when defending their transgressions: deontology, utilitarianism, rational self-interest, Machiavellianism, cultural relativism, or situational ethics. Understanding which theory of ethical reasoning students employ is critical, as preemptive steps can be taken by faculty to counteract this reasoning and prevent plagiarism. Additionally, it has been demonstrated that unethical behavior in school can lead to unethical behavior in business; (...) therefore, correcting unethical behavior in school can have a positive impact on organizational ethics. To meet this objective, a content analysis was conducted on the written records of students formally charged with plagiarizing at a large West Coast university. Each case was classified according to the primary ethical reasoning that the student used to justify plagiarism. Results indicate that students predominately invoke deontology, situational ethics, and Machiavellianism. Based on these findings, specific recommendations are offered to curb plagiarism. (shrink)

Suppose that one thinks that certain symmetries of a theory reveal “surplus structure”. What would a formalism without that surplus structure look like? The conventional answer is that it would be a reduced theory: a theory which traffics only in structures invariant under the relevant symmetry. In this paper, I argue that there is a neglected alternative: one can work with a sophisticated version of the theory, in which the symmetries act as isomorphisms.

With aims to both increase organ supply and better reflect individual donation preferences, many nations worldwide have shifted from ‘opt‐in’ to ‘opt‐out’ systems for post‐mortem organ donation (PMOD). In such countries, while a prospective donor's willingness to donate their organs/tissues for PMOD was previously ascertained—at least partially—by their having recorded positive donation preferences on an official register prior to death, this willingness is now presumed or inferred—at least partially—from their not having recorded an objection to PMOD—on an official organ donation (...) register. Using evidence regarding the presence and prevalence of selective donation preferences, and via exploration of how appeals to donation preferences are used to both motivate and legitimate shifts to opt‐out frameworks, this paper draws attention to a set of previously unexplored problems for opt‐out organ donation arising in contexts where: (a) individuals demonstrate selective post‐mortem organ/tissue donation preferences, (b) legislation provides prospective donors with the opportunity to selectively permit/refuse the donation of certain organs/tissues in line with these preferences. While selective preferences pose few problems for opt‐in systems where a selective occasion is built into the process of signing the donor register, this is not the case for opt‐out systems. The loss of this selective occasion can cause significant problems where appeals to preferences motivate/legitimate shifts to opt‐out but evidence regarding variable preferences does not feed into determinations regarding organ/tissue exclusions. The nature of these problems depends on how the authorization aspect of ‘opt‐out’ systems is framed (e.g. as presumed consent, deemed consent or, given the role of familial consent in many jurisdictions as consent in name only).

If a person is competent to consent to a treatment, is that person necessarily competent to refuse the very same treatment? Risk relativists answer no to this question. If the refusal of a treatment is risky, we may demand a higher level of decision-making capacity to choose this option. The position is known as asymmetry. Risk relativity rests on the possibility of setting variable levels of competence by reference to variable levels of risk. In an excellent 2016 article inJournal of (...) Medical Ethics(JME), Rob Lawlor defends asymmetry of this kind by defending risk relativity, using and developing arguments and approaches found in earlier work such as that of Wilks. He offers what we call the two-scale approach: a scale of risk is to be used to set a standard of competence on a scale of decision-making difficulty. However, can this be done in any rational way? We argue it cannot, and in this sense, and to this extent, risk relativity is a nonsense. (shrink)

This paper explains a fallacy that often arises in theorizing about human minds. I call it the Factual Belief Fallacy. The Fallacy, roughly, involves drawing conclusions about human psychology that improperly ignore the large backgrounds of mostly accurate factual beliefs people have. The Factual Belief Fallacy has led to significant mistakes in both philosophy of mind and cognitive science of religion. Avoiding it helps us better see the difference between factual belief and religious credence; seeing that difference in turn enables (...) us to pose interesting normative questions about various mental states labeled “belief.”.

This Element explores what it means for two theories in physics to be equivalent, and what lessons can be drawn about their structure as a result. It does so through a twofold approach. On the one hand, it provides a synoptic overview of the logical tools that have been employed in recent philosophy of physics to explore these topics: definition, translation, Ramsey sentences, and category theory. On the other, it provides a detailed case study of how these ideas may be (...) applied to understand the dynamical and spatiotemporal structure of Newtonian mechanics - in particular, in light of the symmetries of Newtonian theory. In so doing, it brings together a great deal of exciting recent work in the literature, and is sure to be a valuable companion for all those interested in these topics. (shrink)
