This thesis aims to clarify a number of conceptual aspects of the debate surrounding algorithmic fairness. The particular focus here is the role of causal modeling in defining criteria of algorithmic fairness. In Chapter 1, I argue that in the discussion of algorithmic fairness, two fundamentally distinct notions of fairness have been conflated. Subsequently, I propose that what is usually taken to be the problem of algorithmic fairness should be divided into two subproblems, the problem of predictive fairness, and the (...) problem of allocative fairness. At the core of Chapter 2 is the proof of a theorem that establishes that three of the most popular (predictive) fairness criteria are pairwise incompatible. In particular, I show that under certain conditions, a predictive algorithm that satisfies a criterion called counterfactual fairness will with logical necessity violate two other popular predictive fairness criteria called equalized odds and predictive parity. In Chapter 3, a new predictive fairness criterion is developed using a mathematical framework for causal modeling. This fairness criterion, which I call causal relevance fairness, is a relaxation of another popular fairness criterion, counterfactual fairness, but turns out to be more closely in line with philosophical theories of discrimination. In Chapter 4, another infamous impossibility result in algorithmic fairness is analyzed through the lens of causality. I argue that by using a causal inference method called matching, we can modify the two fairness criteria equalized odds and predictive parity in a way that resolves the impossibility. Lastly, Chapter 5 contains an empirical case study. In it, the fairness of a popular recidivism risk prediction tool is analyzed using the criteria of (predictive) fairness developed earlier.

This thesis explores the absent parameters of the ‘social’ in Nietzsche’s works alongside its reception in contemporary political and social theory, responding to renewed concerns with his class racism. Departing from his unsettling ideas on a caste society, breeding and slavery, I argue that Nietzsche’s contemporary reception across the left and right has to be understood as a site of dissonant rhetorical effects. Rather than technically reconstruct Nietzsche’s anti-social positions, I theorize how the hierarchical organisation of the texts facilitates readers’ (...) (mis)identifications, dramatized in the figures of victory and subjugation in his writings, from the ‘philosopher of the future’ to the ‘affirmative woman’. This complements existing reconstructions of Nietzsche’s theory of a two-caste society by centring his rhetorical forms of addressing, conjuring and mobilising his ideal readers towards the project of revaluation. I revisit the discussion on the status of the intertwined biological and social metaphors in Nietzsche’s writings, which have been often sanitized in reception through hermeneutics of suspicion. While readings of Nietzsche in the post-structuralist tradition productively appropriated his suspicions of language as a site of metaphoric transference, sign chains and power relationships, they often ignore Nietzsche’s concerns with degeneration and racial hygiene. Despite Nietzsche’s dangerous socio-biologism, I argue that the philosopher can be still productively used on the Marxist-left as a master of rhetoric. Drawing on Nietzsche’s reception in feminist and post-colonial theory, I argue that the significance of class racism in Nietzsche’s thinking should be theorised in relation to the figure of the noble as a mythical founder of the order of signs. The esoteric figure of the ‘philosopher of the future’ as an experimenter and tempter (Versucher) offers an overarching methodological device through which I delineate Nietzsche’s purchase for centring the role that readers’ self-identifications play in the canonisation of social theories.

I argue for the following: (1) Negotiation is a social construct whereby the parties seek to resolve differences and promote cooperation through a process rooted in mutual consent. (2) Negotiation is a feature of imperfect markets. Where there is a negotiated agreement, there is typically a significant cooperative surplus and, instead of a single market price, a range of possibilities as to how that cooperative surplus may be divided between the parties. The purpose of negotiation is to determine exactly where (...) in that range agreement is reached. (3) The fairness of a negotiated agreement is wholly determined by the fairness of the process that leads to that agreement; and the fairness of the process is itself wholly determined by the adequacy of the constraints applied to that process. This makes negotiation an instance of pure procedural justice. In this regard, negotiation is to be clearly distinguished from judgment or binding arbitration. (4) Negotiated agreement itself implies some degree of consent. But beyond that there are pro tanto obligations on negotiators to (a) behave honestly and, in particular, not lie, (b) seek mutually beneficial outcomes, whereby their counterparties are left no worse off than they would be in the event of a failure to agree, and (c) avoid the abuse of extreme asymmetric negotiating leverage, that characterises a combination of monopoly, monopsony or cartel with essential goods and services, and discriminatory pricing. (5) These constraints are both necessary and sufficient to deliver a fair process and, therefore, a fair outcome. (6) Such constraints can be seen, in part, as attempts to counter market failure and compensate for shortfalls in consent. (7) A further constraint, related to the broader demands of distributive justice, is not called for. Such a requirement is the primary responsibility of society as a whole. To the extent that it does fall on any individual, it takes the form of a separate and narrower duty to aid that can, in cases of dire need, take precedence and require that negotiations cease. (8) The fact that these moral constraints leave the outcome of most negotiations less than fully determined is not a weakness, but a strength of this account. It properly captures the character of a negotiation as a cooperative but also partially adversarial process, during the course of which a fair outcome is constructed – importantly, an outcome that is not predetermined.

From humble beginnings, minds in the natural world have come to take on endless forms. Yet, our best way of studying these minds has come up short. By its own lights, comparative cognitive science has repeatedly struggled to achieve the goals that it has set out for itself. Why is this, and what can be done about it? This dissertation is directed at answering these questions. It does so in two parts. The first addresses the issue of replication; both the (...) looming threat that a replication crisis holds for comparative cognitive science as well as the broader issue of what a replication is. Here, a deflationary account of replication is defended. This view is argued to hold implications for the practice of replication, interpreting replicability as a demarcation criterion, evaluating the replication crisis across the sciences, and evaluating results of replication experiments. Moreover, this analysis holds direct consequences for the evaluation of evidence in comparative cognitive science. Most pointedly, it is not ‘mature’ enough to experience a genuine replication crisis. Nevertheless, replication experiments, when properly framed, can still make valuable contributions to the discipline. The second part builds on the analysis in the first and shows how comparative cognitive science is inhibited by what is termed the ‘validity cycle’. Here, the causes of the validity cycle are initially identified (weak theory, underspecified hypotheses, and underdetermined experiments). Then, four ameliorative proposals that have been made are introduced and their shortcomings are analyzed. These are (1) adopting a bottom-up approach, (2) breaking cognitive capacities into dimensions, (3) formalizing the theories, and (4) identifying signatures of cognitive capacities. Modified versions of each are introduced. Taken together, it is argued that these modified proposals represent the most promising way forward for the science particularly when run simultaneously in a complementary manner. (shrink)

This thesis offers a novel reading of Kant’s Doctrine of Right. It argues that The Doctrine of Right is plausibly read as a sustained exercise in practical political judgment. In the text, Kant reflexively formulates principles of political judgment – including the formal principle of political judgment – the idea of the general united will. According to this principle, to judge politically is to judge as a citizen. The thesis offers this interpretation in contrast to the mainstream of current scholarship (...) on The Doctrine of Right, which is here termed ‘Kantian legalism’. This thesis argues that The Doctrine of Right is a fundamentally political text in which judgment is a key concept. Part One of this thesis begins by tracing the formulation of the idea of the general united will in the first part of The Doctrine of Right ‘Private Right’. The thesis then turns to ‘Public Right’ to argue that Kant’s account of political judgment based on the idea of the general united will stands in contrast to an ideal-theoretic account, the attribution of which to Kant Kantian legalism makes plausible. Part Two substantiates this account through three separate chapters which aim to show the consequences of this reading for interpreting public right in each of its three divisions: right of state, right of nations and cosmopolitan right. By revisiting Public Right, this thesis argues that The Doctrine of Right embraces the contingency of politics from the finite, human perspective that is characteristic of Kant’s philosophy.

Understanding the biological basis of consciousness is one of the central challenges for modern science. Is a mature scientific explanation really possible, and if so, how should consciousness science be organized so as to achieve this? This thesis is a collection of four papers which approach these questions via an account of the natural categories or ‘kinds’, drawn from philosophy of science, to which paradigmatic mental phenomena like consciousness belong. The central claims defended in the thesis are twofold. Firstly, that (...) to facilitate a mature science of consciousness it is crucial to explicitly introduce a new organizing concept of consciousness modelled on the kinds of concepts which underpin previous successful explanations of other natural phenomena – that of a natural kind concept of consciousness. This draws on the general observation that some concepts are better suited to scientific theorizing about the world than others, and thus that progress in scientific and philosophical domains can be (and indeed, has often been) made by working to refine our existing conceptual schemes to reflect this. Secondly, that a mature science of consciousness will be one which recognizes the reality and explanatory importance of a particular category of mental phenomena called ‘global states of consciousness’ which includes dreaming and wakefulness. Examination of this latter claim leads to a third idea explored and motivated in the thesis which brings consciousness science into closer connection with psychiatry. This is the hypothesis that Major Depressive Disorder involves a change to a subject’s global state of consciousness, marking a change from a state of ordinary wakeful consciousness to an altered ‘depressive state’ of consciousness akin to a dream or psychedelic state.

There are two important debates in business ethics that centre on the limited liability business corporation (the corporation). The first debate is whether the corporation has a special normative significance because of its legal form, which means that it comes with special moral responsibilities that are different to moral responsibilities in other, non-corporate contexts. The second debate is whether an egalitarian society should normatively regulate the corporation with stakeholder theory or shareholder value maximisation, where stakeholder theory requires that the corporation (...) gives weight to the interests of all the corporation’s stakeholders and shareholder value maximisation requires that the corporation maximises profits for shareholders, albeit subject to certain constraints. In this thesis, I contribute to these debates by defending two over-arching claims. First, I claim that there are strong pro tanto reasons for society to regulate the corporation with special moral responsibilities because the corporation has a special governmental provenance and comes with special legal privileges for its shareholders. I defend this claim by developing an argument which I call the Corporate Fair Reciprocity Argument, because it is rooted in a conception of justice as fair reciprocity in which justice requires that citizens fairly benefit from and fairly contribute to society as a system of fair social cooperation. Second, I claim that a social egalitarian society, which is plausibly a more specific version of justice as fair reciprocity in which the primary concern of justice is that citizens relate to one another as social equals, has good reasons to favour stakeholder theory. I justify this claim by developing a refined version of stakeholder theory that is grounded in specific social egalitarian values and by defending this version of stakeholder theory as being superior to shareholder value maximisation.

The aim of this thesis is to improve our understanding of how to assess and communicate uncertainty in areas of research deeply afflicted by it, the assessment and communication of which are made more fraught still by the studies’ immediate policy implications. The IPCC is my case study throughout the thesis, which consists of three parts. In Part 1, I offer a thorough diagnosis of conceptual problems faced by the IPCC uncertainty framework. The main problem I discuss is the persistent (...) ambiguity surrounding the concepts of ‘confidence’ and ‘likelihood’; I argue that the lack of a conceptually valid interpretation of these concepts compatible with the IPCC uncertainty guide’s recommendations has worrying implications for both the IPCC authors’ treatment of uncertainties and the interpretability of the information provided in the AR5. Finally, I show that an understanding of the reasons behind the IPCC’s decision to include two uncertainty scales can offer insights into the nature of this problem. In Part 2, I review what philosophers have said about model-based robustness analysis. I assess several arguments that have been offered for its epistemic import and relate this discussion to the context of climate model ensembles. I also discuss various measures of independence in the climate literature, and assess the extent to which these measures can help evaluate the epistemic import of model robustness. In Part 3, I explore the notion of the ‘weight of evidence’ typically associated with Keynes. I argue that the Bayesian is bound to struggle with this notion, and draw some lessons from this fact. Finally, I critically assess some recent proposals for a new IPCC uncertainty framework that significantly depart from the current one. (shrink)

This thesis concerns the measurement of freedom, and its value. Specifically, I am concerned with three overarching questions. First, can we measure the extent of an individual’s freedom? It had better be that we can, otherwise much ordinary and intuitive talk that we would like to vindicate – say, about free persons being freer than slaves – will turn out to be false or meaningless. Second, in what ways is freedom valuable, and how is this value measured? It matters, for (...) example, whether freedom is valuable only insofar as it enables us to pursue specific ends we happen to value for independent reasons, or whether it is also valuable in itself. In the latter case, but not the former, more freedom will always be better. Likewise, it’s important to get clarity on what ends, exactly, freedom is especially instrumentally valuable in promoting, since this goes to how much we should care about it. And finally, the liberal political tradition asserts that there is a special sphere of personal choices within which individuals should be free to do as they please, for reasons over and above the value of freedom itself. Now, can we measure the extent to which states and individuals respect individual liberties, and can we weigh the importance of respecting liberty against competing values like social welfare? To answer these questions, I follow the axiomatic tradition of social choice theory, and I develop several novel measures of freedom – including the first measure of freedom ever proposed that is sensitive to how modally robustly our options are available – a novel approach to measuring the diversity of an opportunity set, and I develop an account of the value of freedom according to which an important part of why freedom matters is that it enables us to improve our preferences through learning, and I construct ways of measuring the value of freedom along this dimension of value. Finally, in later chapters, I provide a representation result for a measure of illiberalism, i.e. of the degree to which states fail to respect the rights of their citizens, and I extend this result to provide a characterization of moral theories that express concern for respecting the rights of others. The final chapter closes by discussing how this concern may be weighed against concerns for social welfare. (shrink)

This thesis has two goals. Firstly, we consider the problem of model selection for the purposes of prediction. In modern science predictive mathematical models are ubiquitous and can be found in such diverse fields as weather forecasting, economics, ecology, mathematical psychology, sociology, etc. It is often the case that for a given domain of inquiry there are several plausible models, and the issue then is how to discriminate between them – this is the problem of model selection. We consider approaches (...) to model selection that are used in classical [also known as frequentist] statistics, and fashionable in recent years methods of Akaike Information Criterion [AIC] and Bayes Information Criterion [BIC], the latter being a part of a broader Bayesian approach. We show the connection between AIC and BIC, and provide comparison of performance of these methods. Secondly, we consider some philosophical arguments that arise within the setting of the model selection approaches investigated in the first part. These arguments aim to provide counterexamples to the epistemic thesis of scientific realism, viz., that predictively successful scientific theories are approximately true, and to the idea that truth and predictive accuracy go together. We argue for the following claims: 1) that none of the criticisms brought forward in the philosophical literature against the AIC methodology are devastating, and AIC remains a viable method of model selection; 2) that the BIC methodology likewise survives the numerous criticisms; 3) that the counterexamples to scientific realism that ostensibly arise within the framework of model selection are flawed; 4) that in general the model selection methods discussed in this thesis are neutral with regards to the issue of scientific realism; 5) that a plurality of methodologies should be applied to the problem of model selection with full awareness of the foundational issues that each of these methodologies has.

It is important to have an adequate model of uncertainty, since decisions must be made before the uncertainty can be resolved. For instance, flood defenses must be designed before we know the future distribution of flood events. It is standardly assumed that probability theory offers the best model of uncertain information. I think there are reasons to be sceptical of this claim. I criticise some arguments for the claim that probability theory is the only adequate model of uncertainty. In particular (...) I critique Dutch book arguments, representation theorems, and accuracy based arguments. Then I put forward my preferred model: imprecise probabilities. These are sets of probability measures. I offer several motivations for this model of uncertain belief, and suggest a number of interpretations of the framework. I also defend the model against some criticisms, including the so-called problem of dilation. I apply this framework to decision problems in the abstract. I discuss some decision rules from the literature including Levi’s E-admissibility and the more permissive rule favoured by Walley, among others. I then point towards some applications to climate decisions. My conclusions are largely negative: decision making under such severe uncertainty is inevitably difficult. I finish with a case study of scientific uncertainty. Climate modellers attempt to offer probabilistic forecasts of future climate change. There is reason to be sceptical that the model probabilities offered really do reflect the chances of future climate change, at least at regional scales and long lead times. Indeed, scientific uncertainty is multi-dimensional, and difficult to quantify. I argue that probability theory is not an adequate representation of the kinds of severe uncertainty that arise in some areas in science. I claim that this requires that we look for a better framework for modelling uncertainty. (shrink)

The thesis proposes, defends, and applies a new model of inter-theoretic reduction, called "Neo-Nagelian" reduction. There are numerous accounts of inter-theoretic reduction in the philosophy of science literature but the most well-known and widely-discussed is the Nagelian one. In the thesis I identify various kinds of problems which the Nagelian model faces. Whilst some of these can be resolved, pressing ones remain. In lieu of the Nagelian model, other models of inter-theoretic reduction have been proposed, chief amongst which are so-called (...) "New Wave" models. I show these to be no more adequate than the original Nagelian model. I propose a new model of inter-theoretic reduction, Neo-Nagelian reduction. This model is structurally similar to the Nagelian one, but differs in substantive ways. In particular I argue that it avoids the problems pertaining to both the Nagelian and New Wave models. Multiple realizability looms large in discussions about reduction: it is claimed that multiply realizable properties frustrate the reduction of one theory to another in various ways. I consider these arguments and show that they do not undermine the Neo-Nagelian of reduction of one theory to another. Finally, I apply the model to statistical mechanics. Statistical mechanics is taken to be a reductionist enterprise: one of the aims of statistical mechanics is to reduce thermodynamics. Without an adequate model of inter-theoretic reduction one cannot assess whether it succeeds; I use the Neo-Nagelian model to critically discuss whether it does. Specifically, I consider two very recent derivations of the Second Law of thermodynamics, one from Boltzmannian classical statistical mechanics and another from quantum statistical mechanics. I argue that they are partially successful, and that each makes for a promising line of future research. (shrink)

This PhD thesis focuses on the philosophical foundations of Neuroeconomics, an innovative research program which combines findings and modelling tools from economics, psychology and neuroscience to account for human choice behaviour. The proponents of Neuroeconomics often manifest the ambition to foster radical modifications in the accounts of choice behaviour developed by its parent disciplines. This enquiry provides a philosophically informed appraisal of the potential for success and the relevance of neuroeconomic research for economics. My central claim is that neuroeconomists can (...) help other economists to build more predictive and explanatory models, yet are unlikely to foster revolutionary modifications in the economic theory of choice. The contents are organized as follows. In chapters 1-2, I present neuroeconomists’ investigative tools, distinguish the most influential approaches to neuroeconomic research and reconstruct the case in favour of a neural enrichment of economic theory. In chapters 3-7, I combine insights from neuro-psychology, economic methodology and philosophy of science to develop a systematic critique of Neuroeconomics. In particular, I articulate four lines of argument to demonstrate that economists are provisionally justified in retaining a methodologically distinctive approach to the modelling of decision making. My first argument points to several evidential and epistemological concerns which complicate the interpretation of neural data and cast doubt on the inferences neuroeconomists often make in their studies. My second argument aims to show that the trade-offs between the modelling desiderata that neuroeconomists and other economists respectively value severely constrain the incorporation of neural insights into economic models. My third argument questions neuroeconomists’ attempts to develop a unified theory of choice behaviour by identifying some central issues on which they hold contrasting positions. My fourth argument differentiates various senses of the term ‘revolution’ and illustrates that neuroeconomists are unlikely to provide revolutionary contributions to economic theory in any of these senses.

I defend the correspondence theory of truth, according to which a statement’s truth consists in a relation of correspondence with extralinguistic fact. There are well-known objections to this view, which I consider and rebut, and also important rival accounts, principal among which are so-called deflationist theories and epistemic theories. Epistemic theories relate the concept of truth to our state of knowledge, but fail, I argue, to respect the crucial distinction between a criterion of truth and the meaning of truth: the (...) view that one cannot do semantics, or metaphysics, without addressing epistemic issues is rejected by this work. Against epistemic theories, I illustrate how truth is independent of epistemic considerations. Deflationism is the more popular of the rival accounts and has gained considerable momentum over the past two decades. It is therefore dealt with in greater detail by this work. Deflationist theories exploit the paradigmatic ‘“Snow is white” is true iff snow is white’ biconditional to argue for an insubstantialist account, according to which truth is conservative with respect to non-semantical facts. On this view, truth’s raison d’être is merely to perform the useful expressive function of generalising over possibly infinite sets of assertions. Against deflationist theories, I claim that the work done by Jeffrey Ketland and Stewart Shapiro conclusively demonstrates how truth is informationally additive over non-semantic facts, while deflationism itself is also an excessively impoverishing theory, inadequate to the tasks it purports to accomplish. This work also defends the thesis that Alfred Tarski’s well-known theory of truth is an authentic correspondence theory. To say this is to say that the clauses of a Tarskian truth-definition can be interpreted in terms of a relation of correspondence that holds between true sentences and the states of affairs they describe. I provide a precise account of what the correspondence in question consists in, claiming that true sentences are homomorphic images of facts, i.e. a true sentence represents, in a form-preserving manner, the truth-making facts in it. This gives precise expression to Wittgenstein’s thesis that true sentences picture the world. (shrink)

Ideology is interpreted broadly in this study as consciousness, where consciousness is the relation of knowledge to its object. This thesis investigates the connection between Hegel’s theory of consciousness and society and Marx’s political and social thought. It shows that many discoveries, previously considered to be those of Marx alone, like surplus-value and the transition from capitalism to communism, were first developed and employed by Hegel. The study also demonstrates that key concepts, which remain only implicit in Marx, such as (...) social class, alienation, revolutionizing praotice, contradiction and dialectic are given full theoretical form only In the works of Hegel. It examines and shows the strong similarities between Hegel’s and Marx’s theory of religion, capitalism and the state, and stresses that their theory details not the conditions for the emancipation of a class, but rather the liberation and freedom of the social individual. The dissertation explores the writings of the young Marx and Feuerbach and shows that Western Marxism, to its theoretical detriment, owes much more to them than it does to Hegel and the mature Marx. The connection between the philosophies of Kant and Feuerbach and the ideology of contemporary bourgeois society is demonstrated, as is the organic, if antagonistic, unity between the alienated consciousness of Western Marxism and that of its bourgeois opponent. Contemporary Marxist theory is subjected to critical analysis within the framework of a comprehensive account of dialectic method and exposition. The thesis concludes that social thought and political action might be enriched and extended through a new synthesis of Marx with Hegel. (shrink)

This thesis is a collection of three self-contained papers on related themes in the area of formal and social epistemology. The first paper explores the possibility of measuring the coherence of a set with multiplicative averaging. It has been pointed out that all the existing probabilistic measures of coherence are flawed for taking the relevance between a set of propositions as the primary factor which determines the coherence of the set. What I show in this paper is that a group (...) of measures, namely the confirmation-based ones, can be saved from this problem if we adopt a nonlinear averaging function to measure the coherence of a set. The second paper discusses how people should conciliate in disagreements. Some epistemologists take linear averaging as the only way of conciliating and claim that conciliating leads to fallacious results. In the paper, I show that the problem is not conciliating, but taking linear averaging as the only way to conciliate. Since there is no reason for us to insist on conciliating with linear averaging, we can adopt nonlinear averaging functions for conciliating and thereby avoid the formal deficiencies. The third paper focuses on the pragmatic results of taking conciliating as a general strategy in disagreements. There is a potential dilemma about conciliating: if everyone always conciliates, it is likely for an epistemic bubble to arise. If everyone refuses to conciliate, an epistemic echo chamber may appear. A possible way of solving the dilemma is to develop a diachronic strategy which tells people how to both conciliate and update their estimate of their interlocutors’ reliability. Although the three papers differ in the subject, they jointly offer some unifying reflections on the way we approach philosophical problems with formal tools. From 5 the first two papers, we see that a formal analysis of a philosophical position is incomplete if philosophers fail to consider a sufficiently wide range of formal tools. The third paper, on the contrary, shows that we should change the ordinary way of modelling a notion if required. This thesis concludes by proposing a pluralistic view of formal methods in formal epistemology. (shrink)

This dissertation offers a phenomenological approach to the comprehension of Information Technology and Strategy, and of the relationships between these two phenomena. We argue that in order thoughtfully to understand the manifold connections between IT and Strategy, their contradictions, shortcomings, and possibilities, one has to rely on the essence of each of these phenomena. The rationale of this approach implied the need to make explicit the ontological assumptions on which the investigation relies. An essential uncovering of that which IT and (...) Strategy are can only take place as long as we lay bare a primary position on the nature of that which is. Martin Heidegger's Being and Time and, to a lesser extent, the theory of autopoiesis are the foundations of this investigation. We claim that these theories are paradigmatically consistent and show relevant complementarities, namely in what concerns the issues of action information, and knowledge. The matching of these two theories provides the ontological and epistemological grounds of the investigation. Within this fundamental setting we argue that IT and Strategy will only essentially show up as long as they are accessed in-the-world in which they are. The research applies the phenomenological method of investigation in its original form as developed by Edmund Husserl. However we extend the Husserlian formulation in a last phase by using the arguments of Heidegger on the opening up of possible concealed meanings of phenomena. The method sets the boundaries of the research. IT and strategy are phenomenological analysed not as empirical objects, event, or states of affairs, but as intentional objects of consciousness. These are formally indicated from the outset of the investigation as the ITness of IT and the Strategyness of Strategy. The central conclusions of the investigation are that IT is an ontological phenomenon substantively penetrating the being-in-the-world we, ourselves, are; and, Strategy, essentially choosing to choose, has been unfolding throughout History guided by the concealed meaning of a striving for an authentic identity. These essential notions uncover a complex set of relationships between the phenomena. Those relationships are thus described and characterised. We also show that although phenomenology is not empirical its results have many important implications for the empirical world. (shrink)

In this thesis I argue that one way scientific descriptions can become self-fulfilling is by promoting social norms among the people they are disseminated to. Identifying this mechanism will enable us to change unwanted social implications caused by it. To make the argument, I rely on the definition of social norms given by Bicchieri [2006] in The Grammar of Society and use the case of microeconomics as it is presented in university textbooks. Thus, the aim of the thesis is to (...) argue that one way microeconomics can be self-fulfilling is by promoting a social norm of self-interest - and often narrow self-interest - via its textbooks and university teaching practices. To do this, I first use the current empirical findings to argue that the dissemination of the rationality assumption as it is presented in microeconomics textbooks can make microeconomics self-fulfilling. Second, I conduct a historical analysis to show that the claims that greed and self-interest are beneficial have been a part of modern economics from its beginning and still is today. I then discuss why the rationality assumption is a part of contemporary microeconomics and analyse how it is presented in standard textbook models today. Here, we see that even though some of the models can account for other-regarding preferences, the textbooks do not mention this fact. Instead, they present the rationality assumption as focusing on self-interested preferences only, and justify it as being both descriptively plausible and normatively desirable. Finally, I use the above analyses to argue that microeconomics textbooks and teaching practices can change people’s behaviour by making them follow a social norm of self-interest in economic situations. I end the thesis by presenting the results of an empirical study designed to test this argument. (shrink)

Laboratory experimentation was once considered impossible or irrelevant in economics. Recently, however, economic science has gone through a real ‘laboratory revolution’, and experimental economics is now a most lively subfield of the discipline. The methodological advantages and disadvantages of controlled experimentation constitute the main subject of this thesis. After a survey of the literature on experiments in philosophy and economics, the problem of testing normative theories of rationality is tackled. This philosophical issue was at the centre of a famous controversy (...) in decision theory, during which a methodology of normative falsification was first articulated and used to assess experimental results. In the third chapter, the methodological advantages of controlled experimentation are illustrated and discussed with examples taken from the experiments on the so-called ‘preference reversal’ phenomenon. Laboratory testing allows to establish with a high degree of certainty that certain phenomena lie behind the experimental data, by means of independent testing, elimination of alternative hypotheses, and the use of different instruments of observation. The fourth chapter is devoted to a conceptual analysis of the problem of ‘parallelism’. This is the problem of inferring from the occurrence of a phenomenon in the laboratory, to its instantiation also in non-laboratory environments. Experimental economists have discussed parallelism at length, and their views are presented and criticised. Eventually, it is argued that parallelism is a factual matter and as such can only be established on empirical grounds. The fifth chapter provides an example of how one can argue for parallelism, focusing on the case of experimentation on the ‘winner’s curse’ phenomenon. The role of experiments as ‘mediators’ between theoretical models and their target domain of application is illustrated, and the structure of parallelism arguments analysed in detail. Finally, in the last chapter, economic experiments are compared to simulations, in order to highlight their specific characteristics. (shrink)

Traditional Chinese Medicine has been criticized for being unscientific because the theory on which it is based involves entities like qi and ’meridians’ that appear ambiguous and because the internal ‘organs’ like the kidney and the spleen are very different from those of modern anatomy and physiology. Even more so, TCM methods of therapy based on the yin-yang principle, the model of the five elements, and the classification of illnesses according to standard constellations of symptoms are largely unproven by the (...) protocols of modern evidence-based medicine. This dissertation attempts to reconstruct TCM theory by: providing explanations of TCM entities as abstractions and constructs that relate to observable body functions and illness symptoms and interpreting TCM theory as comprising heuristic models that were constructed from clinical experience to fit empirical observations of illnesses and their treatments with herbal medications and acupuncture. It suggests that scientists should be less concerned with the ontological status of TCM entities and the epistemic credentials of TCM models than with the ability of these concepts and models to guide physicians in therapy. More importantly, it makes the argument that these models are testable using the methods of evidence-based medicine. There are methodological difficulties associated with randomized controlled trials partly because TCM treatments tend to be individualized and syndromes are dynamic in nature; observational trials may be more appropriate in some situations. It is also possible that, for patients who are more culturally attuned to TCM, the placebo effect is strongly at play and may render the real effects of TCM treatments harder to tease out in clinical trials. The dissertation concludes that the main postulates of TCM should be put to rigorous test. The result may be a leaner but more robust theory, with parts that do not stand up to the test being rejected or modified, and a possible acceptance of its more modest therapeutic claims for a limited range of pathological conditions like pain and chronic illnesses.

"Partial realism" is a common position in the contemporary philosophy of science literature. It states that the "essential" elements of empirically successful scientific theories accurately represent corresponding features the world. This thesis makes several novel contributions related to this position. Firstly, it offers a new definition of the concept of “empirical success”, representing a principled merger between the use-novelty and unification accounts. Secondly, it provides a comparative critical analysis of various accounts of which elements are "essential" to the success of (...) a theory, including structural realism and the divide et impera strategy. A novel account of essentialness, entitled the “empirically successful sub-theory "account", is defended. Thirdly, it is argued that the realism/anti-realism debate should put to the side metaphysical questions and focus instead on partial realism's commitment to the continuity of science. Because this commitment lacks metaphysical implications, it is referred to as "deflationary realism". Anti-realists cannot reject deflationary realism as a matter of a priori principle; its overall viability can therefore only be assessed by a careful examination of the history of science. Finally, another consequence of partial realism, named "partial rationalism", is defended. Partial rationalism states that, in cases where several competing theories have been suggested, scientists are rational just in case they accept the essential elements of each of the scientific theories on offer. This novel position subverts the existing literature on scientific "revolutions", as it sometimes demands that scientists devise a synthesis between competing scientific theories, instead of "choosing" only one. The philosophical points defended in this thesis are illustrated and supported by case studies from the history of science, including Fresnel’s wave theory of light, the Copernican revolution, the "neo-Darwinian synthesis" in evolutionary biology, the "prion revolution" in molecular biology, the miasma theory of disease, and the chemical revolution.

Contemporary political liberalism defends the view that any legitimate law ought to be justified to those reasonable citizens subject to it. A standard way in which to accomplish this task is to construct a set of public reasons, comprised of constitutional essentials and public democratic values, which are then used to justify all political mandates. The dissertation begins with a criticism of this process of justification for outcomes of legitimate procedures of public decision-making. It argues that given how reasons contribute (...) to judgment formation, it is highly optimistic to assume that reasonable consent on procedures of collective decision-making correspond to the justifiability of procedural outcomes. Instead, I argue for an ideal of legitimate decision-making which enables each citizen to assume a threshold level of personal responsibility for all political decisions made by the political collective. Integrating responsibility into a theory of liberal legitimacy requires a reformulation of the rules of public justification. I argue that citizens concerned with making responsible political decisions must be allowed to justify their political positions through both reasonable judgments as well as sympathetic judgments such as compassion for those who live with disability and mercy towards the criminally motivated. The notion of sympathy, as formulated by David Hume and expanded by Adam Smith, provides an account of how individuals’ ethical evaluations are affected by their ability to be in fellow-feeling with other people. A substantial portion of my doctoral thesis considers the situations in which a private judgment couched in sympathetic terms can meet political liberalism’s demands of publicity and reciprocity.

You and I lead different lives. While we share a society and a world, our existence is separate from one another. You and I matter individually, by ourselves. My dissertation is about this simple thought. I argue that this simple insight, the separateness of persons, tells us something fundamental about morality. My dissertation seeks to answer how the separateness of persons matters. I develop a precise view of the demands of the separateness of persons. The separateness of persons imposes both (...) a requirement on the justification of first-order moral principles as well as a requirement on the content of first-order moral principles. In specifying these demands, I argue that respecting the separateness of persons requires taking into consideration each person’s point of view separately. This requires taking into account the moral relations in which individuals stand to one another. I make use of this relational understanding of the separateness of persons to advance various debates in moral and political philosophy. I argue for a framework to assess to which extent the veil of ignorance can be reconciled with the separateness of persons. I also argue for a new view on the ethics of risk which is a form of contractualism that discounts risks only by their objective risk. Furthermore, I argue for a new solution to the problem of aggregation that is skeptical of aggregation and can set plausible limits to aggregation. Lastly, I provide a new relational agent-based justification for deontological constraints. In addition to answering how the separateness of persons matters, I defend the separateness of persons against challenges. Most importantly, I argue that the importance of the separateness of persons is not undermined even if we believe that our personal identity, i.e. whether we persist as the same person, is unimportant.

Taking Savage's subjective expected utility theory as a starting point, this thesis distinguishes three types of uncertainty which are incompatible with Savage's theory for small worlds: ambiguity, option uncertainty and state space uncertainty. Under ambiguity agents cannot form a unique and additive probability function over the state space. Option uncertainty exists when agents cannot assign unique consequences to every state. Finally, state space uncertainty arises when the state space the agent constructs is not exhaustive, such that unforeseen contingencies can occur. (...) Chapter 2 explains Savage's notions of small and large worlds, and shows that ambiguity, option and state space uncertainty are incompatible with the small world representation. The chapter examines whether it is possible to reduce these types of uncertainty to one another. Chapter 3 suggests a definition of objective ambiguity by extending Savage's framework to include an exogenous likelihood ranking over events. The definition allows for a precise distinction between ambiguity and ambiguity attitude. The chapter argues that under objective ambiguity, ambiguity aversion is normatively permissible. Chapter 4 gives a model of option uncertainty. Using the two weak assumptions that the status quo is not uncertain, and that agents are option uncertainty averse, we derive status quo bias, the empirical tendency for agents to choose the status quo over other available alternatives. The model can be seen as rationalising status quo bias. Chapter 5 gives an axiomatic characterisation and corresponding representation theorem for the priority heuristic, a heuristic which predicts binary decisions be- tween lotteries particularly well. The chapter analyses the normative implications of this descriptive model. Chapter 6 defends the pluralist view of decision theory this thesis assumes. The chapter discusses possible applications of the types of uncertainty defined in the thesis, and concludes. (shrink)

The thesis explores the question of how should a rational moral agent reason and make choices when he finds himself accepting inconsistent moral judgments. It is argued that it is both conceptually and psychologically justified to describe such an agent as suffering from uncertainty. Such uncertainty, however, is not uncertainty regarding the truth of some descriptive claim, but rather uncertainty regarding the truth of a normative claim. Specifically it is uncertainty regarding the truth of a moral judgement. In the literature (...) this is sometimes called “moral uncertainty”. Two different lines of philosophical literatures that explore the idea of moral uncertainty are discussed. The first line – the one that originated from David Lewis‟ argument against the “Desire as Belief Thesis” – explores the mere possibility of moral uncertainty, while the second line explores the question how ought a rational moral agent choose in face of moral uncertainty. The discussion of these two lines of research leads to the conclusion that a consistent account of moral decision making under conditions of moral uncertainty that will be applicable to the kind of cases that the thesis explores, must make use of degrees of beliefs in comparative moral judgements and of them alone. Specifically, no references to degrees of moral value should be made. An attempt to present such an account in the framework of an extension of Leonard Savage‟s model for decision making is carried out. This attempt leads to a problematic result. Several implications of the result to ethic and meta-ethics are discussed as well as possible ways to avoid it. The conclusion is partly positive and partly negative: While a plausible account of moral decision making under conditions of moral uncertainty is presented, an account of moral reasoning that aims at finding a complete moral theory is shown to be a very difficult – if not impossible - aim to achieve.

The theory of choice receives formal treatment in decision theory, game theory and substantial parts of economics. However there is cause for concern that the formal treatment of the subject has advanced beyond the substantive grounds on which it relies. For, the formal theories fundamentally rely on a concept of preference, which is itself lacking a viable substantive interpretation. Indeed the challenges to the substantive interpretation of ‘preference’ threaten to undermine the standard arguments used to justify the completeness and transitivity (...) conditions on which Preference Theories rely. This discussion will explore whether a conception of rationality, anchored in a larger conception of practical reasoning, can justify the completeness and transitivity conditions. Specifically, this dissertation will draw on recent developments in philosophy of law, action theory and ethics to enumerate a conception of practical reasoning that takes reasons to be the basic normative concept. It will then seek to offer an account of rationality that is distinct from, but complementary to, the role of reasons. And from this foundation develop an account of preferences that includes many of the characteristics of standard accounts, yet is situated within this broader context. From this vantage point, the discussion will explore possible justifications for the completeness and transitivity conditions. Ultimately, it will be argued that both can be justified – though with different force – in specified domains. While the discussion will primarily focus on the justification of the completeness and transitivity conditions, it is in part motivated by the goal of exploring the connections between the treatment of choice in the distinct fields associated with Preference Theories and action theory broadly defined. In so doing, the hope is to suggest that there is promise in drawing together formal and substantive treatments of choice which is deserving of greater attention. (shrink)

This thesis makes two claims: first, that conflict is constitutive of human agency, and second, that this understanding of agency in terms of conflict makes politics a problem about the will. I develop an argument to show how these two claims weave together to create the fabric of Kant’s account of political willing. From this Kantian approach to conflict and agency, the systematic question animating this thesis thereby arises: what are the conditions that make political willing possible? This thesis defends (...) the notion of political willing as a placeholder for a number of inter-woven conditions that make political life in common possible. As a form of rightful interaction between free agents of choice, this form of willing emerges in Kant from the constitutive features of what it means to be an agent in a world with others agents. This relation between agents makes conflict unavoidable, a conflict which only a will that is public, omnilateral, and coercive, can rightfully resolve. I trace the development of this model of political willing in three spheres of Kant’s thought: individual ethics, teleology, and politics. I conclude that Kant’s view of politics is, in some ways, more Hobbesian than Hobbes’: for Kant, conflict cannot and should not be fully eradicated, if we are to take seriously equality between agents. Life under the state is not conflict-free, but rather it is a sphere made to preserve and to safeguard the boundaries of a shared political life, always prone to conflict. (shrink)

This dissertation aims to determine the optimal level of granularity for the variables used in probabilistic causal models. These causal models are useful for generating explanations in a number of scientific contexts. In Chapter 1, I argue that there is rarely a unique level of granularity at which a given phenomenon can be causally explained, thereby rejecting various causal exclusion arguments. In Chapter 2, I consider several recent proposals for measuring the explanatory power of causal explanations, and show that these (...) measures fail to track the comparative depth of explanations given at different levels of granularity. In Chapter 3, I offer a pragmatic account of how to partition the measure space of a causal variable so as to optimally explain its effect. My account uses the decision-theoretic notion of value of information, and indexes the relative depth of an explanation to a particular agent faced with a particular decision problem. Chapter 4 applies this same decisiontheoretic framework to answer the epistemic question of how to discover constitutive relationships in nature. In Chapter 5, I describe the formal details of the relationship between random variables that are meant to be coarse-grained and fine-grained representations of the same type of phenomenon. I use this formal framework to rebut a popular argument for the view that special science probabilities can be objective chances. Chapter 6 discusses challenges related to the causal interpretation of Bayes nets that use imprecise rather than precise probabilities. (shrink)

Intuitively, an agent who does harm behaves differently from an agent who allows harm to happen. This thesis examines the distinction between doing harm and merely allowing it to occur. I argue that this distinction is morally relevant, and doing harm is harder to justify than allowing harm, but that there is not always a fact of the matter how the distinction ought to be drawn. In Chapters 1 and 2, I survey the main alternative accounts for explaining the difference (...) between “doing” and “allowing”. I compare causal approaches, which distinguish doing and allowing on the basis of how an agent caused an outcome, with “norm-based” accounts, which explain the distinction appealing to independent moral features. I conclude that a “mixed” causal account, such as Hitchcock's self-contained network model, is the most promising for tracking doing/allowing classifications. I then examine whether this distinction is morally relevant. I outline two theoretical hypotheses, the “positive” and the “negative” theses. The former argues that there is a fact of the matter whether an action is “doing” or “allowing”, and this classification is morally significant; the latter that there might or might not be such a fact of the matter, but in any case this distinction is not morally relevant. In Chapter 3, I critique an influential strategy for settling this issue, that is, comparing “fully-equalized cases”. In Chapter 4, I consider the import of “framing effects”. Despite attempts to use fully-equalized cases or evidence of framing in support of either thesis, these strategies are not compelling. In Chapters 5 and 6, I present my alternative thesis, which relies on the self-contained network model. I define “doings” as instances where an outcome counterfactually depends on the agent, within a “self-contained” network, and “allowings” as instances where the outcome depends on the agent, within a “non-self-contained” network. This classification captures whether an agent is causally relevant to an outcome in a specific way; nonetheless, the identification of “selfcontained” networks incorporates agents' empirical and normative expectations. The distinction is thus morally relevant, as it captures moral considerations, but may be ultimately ambiguous, as there may not always be a fact of the matter as to how the distinction should be drawn.

An attempt is made here to examine the analysis three political thinkers - Thomas Paine, William Godwin, and Jeremy Bentham have offered of the idea of equality. The inquiry underrtaken is philosophical and not historical in character, since no attempt is made either at tracing the influence ht the biographical-cum-intellectual level of one of them upon the other or at treating their ideas on equality as born out of their preoccupation with the same problem to which they give various answers (...) and which can therefore be considered within a single overall framework. Instead, each thinker is considered independently. And a study is undertaken of the way he understands equality, the way he justifies it, the sort of equality he considers most important and his reasons for this, the area of life he takes the idea of equality to illuminate, the manner in which he relates it to other ideas, etc.. In each case, a fairly coherent philosophy of equality is sought to be constructed out of their respective writings. These three thinkers are selected for two reasons. The idea of equality looms quite large in their thought; as such, it was felt that looking at their writings from the standpoint of equality may illuminate their certain features that may otherwise remain obscure or relatively underemphasized. Further, as they consider equality from different philosophical positions it was believed that a critical examination of their writings could, perhaps, point to the general merits and limitations of their respective positions in terms of equality. in chapter I, it is argued that there are distinct views of God discernible in Paine's writings, and that corresponding to them are three distinct views of equality, though only two of them are discussed by Paine at any length. in chapter II, it is argued that, though Godwin begins as a thoroughgoing rationalist, three are shifts in his general philosophical position, and that, with each shift, his ideas on truth, rationality and equality undergo important changes. Finally, in chapter III, it is argued that there are two distinct theories of equality in Bentham and that tension between them remains unresolved. (shrink)

This thesis studies some philosophical and ethical issues that economic design raises. Chapter 1 gives an overview of economic design and argues that a crossfertilisation between philosophy and economic design is possible and insightful for both sides. Chapter 2 examines the implications of mechanism design for theories of rationality. I show that non-classical theories, such as constrained maximization and team reasoning, are at odds with the constraint of incentive compatibility. This poses a problem for non-classical theories, which proponents of these (...) theories have not addressed to date. Chapter 3 proposes a general epistemology of economic engineering, which is motivated by a novel case study, viz. the reform of a matching market for medical practitioners. My account makes use of causal graphs to explain how models allow encoding counterfactual information about how market outcomes change if the design of the market changes. The second part of the thesis examines ethical issues. In Chapter 4, I apply tools from matching theory to gain insights into the distribution of refugees, such as among countries of the European Union. There is an ethical trade-off between the fairness of matchings and their efficiency, and I argue that in this context, fairness is the morally weightier criterion. Chapter 5 deals with the ethics of kidney exchange. Against critics, I give two arguments for the implementation of kidney exchange programmes. The first argument is that they are instrumental in meeting a moral obligation, namely to donate effectively. The second is that kidney exchange may increase the motivation for altruistic donations, because the donation of one kidney may trigger > 1 life savings. The final chapter identifies questions for future research and it closes with some thoughts about the future trajectory of economic design. (shrink)

This thesis is about four ethical problems concerning death. The first two chapters are about the reasons we have to prolong our own lives. In Chapter 1, I argue that we can defensibly maintain that it would not have been in our interests to have been brought into existence earlier than we were, while also holding that it is often against our interests to die earlier than we otherwise would. In Chapter 2, I argue that one can have a reason (...) to continue one’s conscious life even when the particular contents of it will not be good on balance. The last two chapters are about the morality of taking life. In Chapter 3, I argue against the common-sense view that the strength of the moral objection to killing a person is unaffected by certain facts about her, chief among them what she stands to lose by dying. In Chapter 4, I discuss the nature and extent of the obligations that are incurred by those who wrongfully kill, or who mistreat people in other ways that seem, on the surface, impossible to redress.

According to the traditional Bayesian view of credence, its structure is that of precise probability, its objects are descriptive propositions about the empirical world, and its dynamics are given by conditionalization. Each of the three essays that make up this thesis deals with a different variation on this traditional picture. The first variation replaces precise probability with sets of probabilities. The resulting imprecise Bayesianism is sometimes motivated on the grounds that our beliefs should not be more precise than the evidence (...) calls for. One known problem for this evidentially motivated imprecise view is that in certain cases, our imprecise credence in a particular proposition will remain the same no matter how much evidence we receive. In the first essay I argue that the problem is much more general than has been appreciated so far, and that it’s difficult to avoid without compromising the initial evidentialist motivation. The second variation replaces descriptive claims with moral claims as the objects of credence. I consider three standard arguments for probabilism with respect to descriptive uncertainty—representation theorem arguments, Dutch book arguments, and accuracy arguments—in order to examine whether such arguments can also be used to establish probabilism with respect to moral uncertainty. In the second essay, I argue that by and large they can, with some caveats. First, I don’t examine whether these arguments can be given sound non-cognitivist readings, and any conclusions therefore only hold conditional on cognitivism. Second, decision-theoretic representation theorems are found to be less convincing in the moral case, because there they implausibly commit us to thinking that intertheoretic comparisons of value are always possible. Third and finally, certain considerations may lead one to think that imprecise probabilism provides a more plausible model of moral epistemology. The third variation considers whether, in addition to conditionalization, agents may also change their minds by becoming aware of propositions they had not previously entertained, and therefore not previously assigned any probability. More specifically, I argue that if we wish to make room for reflective equilibrium in a probabilistic moral epistemology, we must allow for awareness growth. In the third essay, I sketch the outline of such a Bayesian account of reflective equilibrium. Given that this account gives a central place to awareness growth, and that the rationality constraints on belief change by awareness growth are much weaker than those on belief change by conditionalization, it follows that the rationality constraints on the credences of agents who are seeking reflective equilibrium are correspondingly weaker.

What kind of thing do you believe when you believe that you are in a certain place, that it is a certain time, and that you are a certain individual? What happens if you get lost, or lose track of the time? Can you ever be unsure of your own identity? These are the kind of questions considered in my thesis. Beliefs about where, when and who you are are what are called in the literature de se, or self-locating beliefs. (...) This thesis examines how we can represent de se beliefs, and how we can reason about de se uncertainty. In the first part of the thesis, I present and motivate a specific account of the content of de se belief, based on the one given by David Lewis. On this account, the content of de se beliefs are centred propositions. I defend this view against a rival account, put forward by Robert Stalnaker, according to whom the content of de se beliefs are ordinary propositions. In the second part of the thesis, I explore how we can reason probabilistically about de se uncertainty. I start by defining probabilities over centred propositions, and investigate what probabilities mean in this context. As it turns out, all the main interpretations of probability can be extended to centred propositions. The only trouble seems to arise for the Bayesian principle of updating via conditionalization. After giving a diagnosis of the problem, I offer a solution by formulating a natural extension of conditionalization, which I argue preserves the essential features of Bayesian reasoning. In the final chapter, I apply my view and show that it leads to a natural resolution of a puzzle that is generally taken to be a test case for any account of centred updating. (shrink)

Sometimes people ought to do something for the sake of equality but it would be wrong to force them to do it. Contrariwise, sometimes it would be permissible to force people to do something for the sake of equality but it is unclear whether they ought to do it without coercion. This gives rise to moral obstacles to redistributing benefits and burdens in unequal situations of different degrees and kinds. In these situations, what are individuals required to do, permitted to (...) do, and forbidden from doing for the sake of equality? In this thesis, I address four aspects of this problem. I defend the following central claims. When we fall short of realising equality using the coercive power of the state, individuals have an egalitarian reason to take up the moral slack and voluntarily redistribute their own wealth, even when this makes them worse off than they would be if society were equal. It is sometimes permissible for individuals to flout property laws in the name of equality by dispossessing people of things that they are legally, but not morally, entitled to. This is often true when property laws are severely unjust and is sometimes true when property laws are only partially unjust. Egalitarian justice requires people to benefit each other by making a productive contribution to society in order to realise a Pareto optimal level of equality. This is neither implausibly morally demanding, nor commits one to the view that justice licences legally coercive job allocation. Sometimes, due to brute bad luck, indivisible harm will occur and cannot be fairly divided. Some views say that it is wrong to harm innocent people in the course of defending yourself from an equivalent harm, but permissible to “duck” harm even though you foresee that doing so will lead to an innocent person being harmed as a result. I argue that, by the lights of such views, the mode of agency used to impose or redistribute harm makes no difference to permissibility. (shrink)

This thesis addresses several questions regarding what rational agents ought to believe and how they ought to act. In the first part I begin by discussing how scientists contemplating several mutually exclusive theories, models or hypotheses can reach a rational decision regarding which one to endorse. In response to a recent argument that they cannot, I employ the tools of social choice theory to offer a ‘possibility result’ for rational theory choice. Then I utilize the tools of judgment aggregation to (...) investigate how scientists from across fields can pool their expertise together. I identify an impossibility result threatening such a procedure and prove a possibility result which requires that some scientists sometimes waive their expertise over some propositions. In the second part I first discuss the existing justifications for a restricted principle of indifference that mandates that two agents whose experiences are subjectively indistinguishable should be indifferent with respect to their identities. I argue that all existing justifications rely on the same mistaken reasoning behind the ‘staying’ strategy in the Monty Hall problem. Secondly, I show this mistake is more widespread and I identify it in arguments purporting to show the failure of two reflection-like principles. In the third part I look at a recent argument that fair policy makers face a dilemma when trying to correct a biased distributive process. I show the dilemma only holds if the correction has to happen in one-shot. Finally, I look at how we ought to design public restrooms so that we reduce the discrimination faced by minority groups. I make the case for opening our public restrooms to all genders. (shrink)

Policy-makers face an uncertain world. One way of getting a handle on decision-making in such an environment is to rely on evidence. Despite the recent increase in post-fact figures in politics, evidence-based policymaking takes centre stage in policy-setting institutions. Often, however, policy-makers face large volumes of evidence from different sources. Robustness analysis can, prima facie, handle this evidential diversity. Roughly, a hypothesis is supported by robust evidence if the different evidential sources are in agreement. In this thesis, I strengthen the (...) case for the use of robustness analysis in evidence-based policymaking by answering open research questions about this inference technique. First, I argue that existing taxonomies miss a fruitful category of robustness reasoning, that is predictive stability. Second, I claim that derivational robustness analysis – the investigation of whether the results of different models are in agreement – can yield interesting insights even if not the entire relevant model space is covered by available models or if the model results are only partially in agreement. Third, I claim that expert knowledge is necessary to address questions that arise when one applies measurement robustness analysis – the investigation into whether multiple means of measurement yield the same result. Finally, I argue that, in situations where evidence from different measurements is not in agreement, it can be advisable to no longer take all of the evidence into account. This can be done in a rationally defensible way by choosing the most adequate theory or model underlying parts of the evidence set. I discuss examples from climate, medical, and economic policy-making to establish my claims. (shrink)

This thesis engages with the following three questions. First, how should the presence of risk and ambiguity affect how we distribute a benefit to which individuals have competing claims? Second, what is it about the imposition of a risk of harm itself, such as the playing of Russian roulette on strangers, which calls for justification? Third, in the pursuit of the greater good, when is it permissible to foreseeably generate harms for others through enabling the agency of evildoers? Chapters 1 (...) through 3 of the thesis provide an answer the first question. Chapter 1 defends the importance of a unique complaint of unfairness that arises in risky distributive cases: that sometimes individuals are better off at the expense of others. Chapter 2 defends a view called Fairness as Proper Recognition of Claims which guides how a decision-maker ought to act in cases where individuals have unequal claims to a good. Chapter 3 considers how the presence of ambiguity affects distributive fairness, and defends an egalitarian account of the evaluation of ambiguous prospects. Chapter 4 provides an answer to the second question through a defence of the Insecurity Account, which is a unique way in which impositions of risks of harm can be said to harm individuals, namely by rendering the victim’s interests less secure. Chapter 5 provides an answer to the third question by defending what I call the Moral Purity Account, to explain when it is permissible to provide aid in cases where individuals are harmed as a foreseeable consequence of the provision of such aid.

My thesis explores alternatives to the orthodox model of decision theory. I criticise it by focusing on motivations that, for different reasons, I believe should not be labelled as a consequence. I start by describing what I call the orthodox theory of choice. I describe both the theories proposed by Von Neumann and Morgenstern, and Savage. This is followed by a discussion of the individuation strategy, and, in particular, John Broome’s proposal of an individuation by justifiers ). I then focus (...) on the Allais’s problem, and on how individuation can be employed to solve the problematic situation in which it puts orthodox decision theory. I argue against the practice of using this strategy as a general solution to cases such as the Allais’s problem. I then extend the concerns raised by the Allais’s problem to motivations that do not concern probabilities. I focus on dynamic decision making, and on a property of certain actions that arises from the passage of time: hope. This is interesting because it is no longer the probabilities that affect the decision maker, but an element that is not even represented in the standard model, namely time. I then describe the Kreps and Porteus’s model ) for a preference for the timing of the resolution of uncertainty, where a preference for either early or late resolution of uncertainty is modelled explicitly. I show how making time an explicit part of the model allows one to model utility as depending on something other than consequences, while not violating dynamic consistency. I use the above case to claim that in some contexts - for example, if the decision maker is deciding for herself, and time is passing - it is preferable to model concerns that do not quite fit the label of a consequence explicitly, because the benefits of doing so surpass the costs. This seems to indicate that decision theory should be moving towards a pluralist approach, where different models are used depending on the decision context. (shrink)

Scientific models are important, if not the sole, units of science. This thesis addresses the following question: in virtue of what do scientific models represent their target systems? In Part i I motivate the question, and lay out some important desiderata that any successful answer must meet. This provides a novel conceptual framework in which to think about the question of scientific representation. I then argue against Callender and Cohen’s attempt to diffuse the question. In Part ii I investigate the (...) ideas that scientific models are ‘similar’, or structurally morphic, to their target systems. I argue that these approaches are misguided, and that at best these relationships concern the accuracy of a pre-existing representational relationship. I also pay particular attention to the sense in which target systems can be appropriately taken to exhibit a ‘structure’, and van Fraassen’s recent argument concerning the pragmatic equivalence between representing phenomena and data. My next target is the idea that models should not be seen as objects in their own right, but rather what look like descriptions of them are actually direct descriptions of target systems, albeit not ones that should be understood literally. I argue that these approaches fail to do justice to the practice of scientific modelling. Finally I turn to the idea that how models represent is grounded, in some sense, in their inferential capacity. I compare this approach to anti-representationalism in the philosophy of language and argue that analogous issues arise in the context of scientific representation. Part iii contains my positive proposal. I provide an account of scientific representation based on Goodman and Elgin’s notion of representation-as. The result is a highly conventional account which is the appropriate level of generality to capture all of its instances, whilst remaining informative about the notion. I illustrate it with reference to the Phillips-Newlyn machine, models of proteins, and the Lotka-Volterra model of predator-prey systems. These examples demonstrate how the account must be understood, and how it sheds light on our understanding of how models are used. I finally demonstrate how the account meets the desiderata laid out at the beginning of the thesis, and outline its implications for further questions from the philosophy of science; not limited to issues surrounding the applicability of mathematics, idealisation, and what it takes for a model to be ‘true’.

Biochemists often adopt what may be called the “Strategy of Decomposition” for the causal discovery of biochemical pathway dynamic behaviours. This involves decomposing a pathway into a set of isolated parts, which are then analysed separately. It is assumed that knowledge gained of the isolated parts can then be used to explain the dynamic behaviours of the whole pathway. My thesis addresses the extent to which use of the Strategy of Decomposition is warranted. I evaluate two challenges contained in Bechtel (...) and Richardson’s Discovering Complexity. The first challenge is that pathways lack the ‘modular’ structure assumed in the Strategy of Decomposition. Bechtel and Richardson take biochemists to use a concept of modularity called ‘near decomposability’. The second challenge is that pathways have ‘Pathway Emergent’ behaviours. I reject both challenges. I show that near decomposability is the wrong type of modularity to apply to pathways, and that the occurrence of Pathway Emergence has not been established. I argue that an underlying problem with Bechtel and Richardson’s analyses is that they overstate the consequences of feedback and nonlinearity for the Strategy of Decomposition. Instead, the analysis of pathway modularity and emergence needs to be centered on the context-sensitivity of pathways’ ‘local causal laws’. I identify that the type of modularity assumed in the Strategy of Decomposition is ‘causal law modularity’, which requires the invariance of local causal laws. I also identify a necessary condition for Pathway Emergence: a pathway must manifest at least one local causal law that is not manifested by its isolated parts. I argue that the use of the Strategy of Decomposition may often be unwarranted. This is because the local causal laws of pathways are highly context-sensitive, and pathways might often not be causal law modular. This context-sensitivity also leaves open the possibility of Pathway Emergence. (shrink)

One of the conceptual limitations of the orthodox game theory is its inability to offer definitive theoretical predictions concerning the outcomes of noncooperative games with multiple rationalizable outcomes. This prompted the emergence of goal-directed theories of reasoning – the team reasoning theory and the theory of hypothetical bargaining. Both theories suggest that people resolve non-cooperative games by using a reasoning algorithm which allows them to identify mutually advantageous solutions of non-cooperative games. The primary aim of this thesis is to enrich (...) the current debate on goaldirected reasoning theories by studying the extent to which the principles of the bargaining theory can be used to formally characterize the concept of mutual advantage in a way which is compatible with some of the conceptually compelling principles of orthodox game theory, such as individual rationality, incentive compatibility, and non-comparability of decision-makers’ personal payoffs. I discuss two formal characterizations of the concept of mutual advantage derived from the aforementioned goal-directed reasoning theories: A measure of mutual advantage developed in collaboration with Jurgis Karpus, which is broadly in line with the notion of mutual advantage suggested by Sugden, and the benefit-equilibrating bargaining solution function, which is broadly in line with the principles underlying Conley and Wilkie’s solution for Pareto optimal point selection problems with finite choice sets. I discuss the formal properties of each solution, as well as its theoretical predictions in a number of games. I also explore each solution concept’s compatibility with orthodox game theory. I also discuss the limitations of the aforementioned goal-directed reasoning theories. I argue that each theory offers a compelling explanation of how a certain type of decision-maker identifies the mutually advantageous solutions of non-cooperative games, but neither of them offers a definitive answer to the question of how people coordinate their actions in non-cooperative social interactions.

My thesis demonstrates that, despite a number of impossibility results, a satisfactory and coherent theory of population ethics is possible. It achieves this by exposing and undermining certain key assumptions that relate to the nature of welfare and personal identity. I analyse a range of arguments against the possibility of producing a satisfactory population axiology that have been proposed by Derek Parfit, Larry Temkin, Tyler Cowen and Gustaf Arrhenius. I conclude that these results pose a real and significant challenge. However, (...) in the absence of further evidence I reject the conclusion that they imply that the value of populations is either not precise or not transitive. Instead, I expose some fundamental assumptions behind these results. One key assumption is that something can only make a life better or worse if it makes that life better or worse for the person living it, i.e. it raises or lowers the ‘welfare level’ of that life. Although intuitively highly plausible, this assumption ignores the possibility that perspectives other than that of the person living a life may be relevant for evaluating the components of that life and that these should be incorporated into our all things considered judgements. I argue that episodes within a person’s life that are strongly psychologically connected may have a special normative significance, particularly if these episodes involve such things as the enjoyment of ‘the best things in life’ or the experience of great suffering. We have reason to assign an all things considered value to such strongly psychologically connected phases of a person’s life, where this value is not exhausted by the contributions these make to the welfare level of that person’s life as a whole. It follows that our all things considered evaluations of populations are often underdetermined by information about the welfare levels of the lives they contain. However, in certain cases, most notably in that of ‘the Repugnant Conclusion’, there is nevertheless sufficient information provided by the welfare levels of persons’ lives to allow us to infer facts about these components that make an all things considered difference to these evaluations. I argue that a failure to acknowledge these facts is the cause of the aforementioned impossibility results and that once they are taken into account it is possible to produce a satisfactory theory of population ethics.

Hierarchies of evidence are an important and influential tool for appraising evidence in medicine. In recent years, hierarchies have been formally adopted by organizations including the Cochrane Collaboration [1], NICE [2,3], the WHO [4], the US Preventive Services Task Force [5], and the Australian NHMRC [6,7]. The development of such hierarchies has been regarded as a central part of Evidence-Based Medicine, a movement within healthcare which prioritises the use of epidemiological evidence such as that provided by Randomised Controlled Trials. Philosophical (...) work on the methodology of medicine has so far mostly focused on claims about the superiority of RCTs, and hence has largely neglected the questions of what hierarchies are, what assumptions they require, and how they affect clinical practice. This thesis shows that there is great variation in the hierarchies defended and in the interpretations they are, and can be, given. The interpretative assumptions made in using hierarchies are crucial to the content and defensibility of the underlying philosophical commitments concerning evidence and medical practice. Once this variation is been identified, it becomes clear that the little philosophical work that has been done so far affects only some hierarchies, under some interpretations. Modest interpretations offered by La Caze [11], conditional hierarchies like GRADE [12-14], and heuristic approaches such as that defended by Howick et al. [15,16] all survive previous philosophical criticism. This thesis extends previous criticisms by arguing that modest interpretations are so weak as to be unhelpful for clinical practice; that GRADE and similar conditional models omit clinically relevant information, such as information about variation in treatments’ effects and the causes of different responses to therapy; and that heuristic approaches lack the necessary empirical support. The conclusion is that hierarchies in general embed untenable philosophical assumptions: principally that information about average treatment effects backed by high-quality evidence can justify strong recommendations, and that the impact of evidence from individual studies can and should be appraised in isolation. Hierarchies are a poor basis for the application of evidence in clinical practice. The Evidence-Based Medicine movement should move beyond them and explore alternative tools for appraising the overall evidence for therapeutic claims. (shrink)

We are responsible for some things but not for others. In this thesis, I investigate what it takes for an entity to be responsible for something. This question has two components: agents and actions. I argue for a permissive view about agents. Entities such as groups or artificially intelligent systems may be agents in the sense required for responsibility. With respect to actions, I argue for a causal view. The relation in virtue of which agents are responsible for actions is (...) a causal one. I claim that responsibility requires causation and I develop a causal account of agency. This account is particularly apt for addressing the relationship between agency and moral responsibility and sheds light on the causal foundations of moral responsibility. (shrink)

In this thesis I investigate causal inquiry in the social sciences, drawing on examples from various disciplines and in particular from conflict studies. In a backlash against the pervasiveness of statistical methods, in the last decade certain social scientists have focused on finding the causal mechanisms behind observed correlations. To provide evidence for such mechanisms, researchers increasingly rely on ‘process tracing’, a method which attempts to give evidence for causal relations by specifying the chain of events connecting a putative cause (...) and effect of interest. I will ask whether the causal claims process tracers make are defensible, and where they are not defensible I will ask how we can improve the method. Throughout these investigations, I show that the conclusions of process tracing are constrained both by the causal structure ofthe social world and by social scientists’ aims and values. My central argument is this: all instances of social phenomena have causally relevant differences, which implies that any research design that requires some comparison between cases is limited by how we systematize these phenomena. Moreover, such research cannot rely on stable regularities. Nevertheless, to forego causal conclusions altogether is not the right response to these limitations; by carefully outlining our epistemic assumptions we can make progress in causal inquiry. While I use philosophical theories of causation to comment on the feasibility of a social scientific method, I also do the reverse: by investigating a popular contemporary method in the social sciences, I show to what extent our philosophical theories of causation are workable in practice. Thus, this thesis is both a methodological and a philosophical work. Every chapter discusses both a fundamental philosophical position on the social sciences and a relevant case study from the social sciences. (shrink)

This thesis takes up a rights-based perspective to discuss a number of issues related to the problem of permissible harm. It appeals to a person’s capacity to shape her life in accordance with her own ideas of the good to explain why her death can be bad for her, and why each of us should have primary say over what may be done to her. The thesis begins with an investigation of the badness of death for the person who dies. (...) If death is bad for us, this helps explain the wrongness of killing. The thesis defends the deprivation account—i.e. the idea that death is bad for us when and because it deprives us of good life—against two Epicurean challenges. It adds that death is also bad when and because it thwarts our agency. Next, the thesis deals with the logic of our moral rights to non-interference. It proposes a conception of rights according to which the stringency of our rights derives from and is justified by the rational aspect of our human nature. It argues that this conception of moral rights solves the paradox of deontology. While our rights to non-interference are stringent, they are not absolute. The thesis considers two possible exceptions to the general rule that it is impermissible to harm an innocent person against her consent. First, using an actual case from WWII, it investigates the circumstances under which a government may expose some parts of its population to an increased risk of harm in order to decrease the risk to others. Second, it considers the permissibility of self-defence against an innocent threat. It argues that the potential victim of an innocent threat has a justice-based reason to treat her own interests as on a par with those of the threat. (shrink)

The field of experimental philosophy has received considerable attention, essentially for producing results that seem highly counter-intuitive and at the same time question some of the fundamental methods used in philosophy. A substantial part of this attention has focused on the role of intuitions in philosophical methodology. One of the major contributions of experimental philosophy on this topic has been concrete evidence in support of intuitional diversity; the idea that intuitions vary systematically depending on variables such as ethnicity, socioeconomic background, (...) or gender. Because of the important implications, these findings have been the subject of extensive debate. Despite the seeming significance of the findings and despite all the debates that the experimental philosophy movement has prompted, what has not been examined systematically is the reproducibility of the results. Instead, the reported findings have been simply accepted as established facts. We set out to replicate a wide range of experiments and surprisingly failed to reproduce many of the reported findings, some of which are from the most cited and attention grabbing papers of the field. We draw two conclusions from our findings. The first is that the instability of intuitions has been exaggerated by experimental philosophers. Intuitions appear to be more uniform across different demographic groups. The argument that intuitions need to be discarded because they depend on arbitrary factors such as ethnicity, socioeconomic background, or gender does not seem tenable anymore. The second conclusion is that experimental philosophy needs a better system to ensure the reproducibility of published findings. The current research-publication system of various empirical fields, especially those employing statistical methods, leads to an overproduction of false-positive findings in the published literature. Unless changes are made to the current research-publication system, this overproduction is likely to continue, in experimental philosophy as well as other disciplines. (shrink)

The thesis is a philosophical analysis of the consumption based capital asset pricing model, investigating in particular its epistemological and methodological foundations. Financial markets are integral parts of advanced and developing economies. They matter because they channel unspent household income into banks’ savings accounts and assets such as bonds and stocks. Financial economists have traditionally taken interest in the pricing mechanism that underlies this capital allocation. The consumption based capital asset pricing model is a prominent effort to describe, explain and (...) predict such prices. It tells a story of investors’ trade-off between consumption now and later and which portfolio of assets to hold. The CCAPM based narrative intuitively makes sense, and the chosen methodology involving theoretical assumption, mathematical models and empirical tests follows the professions’ standards of good scientific practise. But does CCAPM’s research programme provide knowledge for use? My thesis seeks to answer this question in a novel way. Instead of embarking on yet another asset pricing research project, I let Philosophy of Science inform my analysis. Following a “primer” introducing essential CCAPM topics and notations, I discuss, in turn, its theoretical foundation, mathematical model, and empirical test results from a philosophy of science perspective. I find that a few fundamental principles and several auxiliary assumptions combine to develop a simplified, partial and idealized theory of investors, financial markets and assets. The model reflects and represents this theory but also makes narrow claims that are distances away from the real situations they target. Unsurprisingly, ideal model assertions fail standard statistical tests of significance. I conclude that mathematical deductive modelling rooted in orthodox, a priori based fundamental principles create ideal and fictional settings that limit their scope and portability. The development of even more granular models within this orthodox paradigm that searches for “event regularities” will not render the desired knowledge for use. The real situations are possibly too complex to be captured in simplified assumptions, ideal theories and mathematical structures. Novel methodological and ontological approaches to asset pricing are in demand. Hence, claims about tendencies in the real data might replace the current focus on point-forecasts. (shrink)
