Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

In this work I examine the reasons offered by David Lewis in favor of tolerance in his works “Mill and Milquetoast” and “Academic Appointments: Why Ignore the Advantage of Being Right?” In the first section I expose and discuss the conception of tolerance that is the target of Lewis’s objections, namely, the conception defended by J.S. Mill. In the second section I expose and discuss Lewis’s main reasons in favor of tolerance and the advantages that, according to Lewis, has his (...) position in relation to that of Mill. In the third section I discuss some of the philosophical and political consequences that seem to follow from Lewis’s proposal and from his criticisms of Mill’s conception of tolerance. (shrink)

It is astonishing that we humans are able to have, act on and express moral beliefs. This dissertation aims to provide a better philosophical understanding of why and how this is possible especially when we assume metaethical expressivism. Metaethical expressivism is the combination of expressivism and noncognitivism. Expressivism is the view that the meaning of a sentence is explained by the mental state it is conventionally used to express. Noncognitivism is the view that the mental state expressed by a moral (...) sentence is a noncognitive, desire-like state. The central question of this dissertation is this: "How can metaethical expressivists explain that we are able to express moral beliefs?" The shortest answer this dissertation will give is the following: "by becoming `dispositional expressivists´." Dispositional expressivists hold that moral beliefs are dispositions to be in certain mental states that resemble desires. More precisely, a central thesis of this study is that to hold a moral belief is to be disposed to be in a desire-like, noncognitive state where this state has some specific structure. This dissertation arrives at and justifies this thesis by making a number of steps. It starts with preparing the ground by developing a general theory of what it is for a sentence to express a mental state. Roughly, this theory states that for a sentence to express a mental state is for that sentence to be conventionally used to perform a speech act which counts as sincere only if the user or speaker is in that mental state. This theory of expressing satisfies all the constraints that must be satisfied for it to be compatible with the purposes of metaethical expressivism. The next step is to provide a solution to the most notorious semantic problem confronting metaethical expressivism, the problem of explaining how sentences containing moral words can have compositional meaning and stand in logical relations also known as the Frege-Geach or embedding problem. Building on the research of Mark Schroeder, a new expressivist semantics, called `Attitude Semantics´, will be developed for a first-order language. The motivating idea underlying attitude semantics is that expressivists can avoid the problematic feature of so-called `biforcation´ if they treat the structures of the mental states expressed by moral sentences as well as that expressed by non-moral sentences as being isomorphic. In order to give those structures a philosophically interesting interpretation, it will be suggested that we treat sentences as expressing dispositional states. As a toy example we will treat the sentence `murder is wrong´ as expressing the disposition to be for blaming for murder. After dealing with the Frege-Geach problem, I turn to the metaethical expressivists' project of quasi-realism. Two major goals of this project are to explain how moral sentence can be truth-apt and how the states expressed by them can be regarded as moral beliefs. In order to establish those goals I critically examine a number of theories of truth-aptness by providing counterexamples to them. I then present my own theory which says that a sentence is truth-apt iff and because there is a conventional way to use it to express a belief. What is new about this theory is that it treats expressing a belief as being explanatorily more basic than being truth-apt. Belief, according to this theory, explains truth-aptness, not vice versa. This has the important consequence that it shows that what I call the `orthodox strategy´ of quasi-realists is mistaken and needs to be inverted: expressivists must `earn the right´ to moral belief before they can establish that moral sentences are truth-apt, and not the other way round. The second part of this dissertation is then concerned with the question of what it is to hold a moral belief and how they can figure in rational reasoning. In short: it is concerned with earning the right to moral belief. After discussing the major problems confronting a noncognitivist theory of belief, most importantly what I call the `tightrope problem´, I argue for a dispositional form of noncognitivism about moral belief that combines elements from Eric Schwitzgebel's dispositionalism about belief and Sebastian Köhler's `conceptual role expressivism´. This dispositional noncognitivism perfectly matches and justifies the dispositionalist interpretation of the expressivist semantics developed before. In order to fully earn the right to moral belief, however, metaethical expressivists must also deal with several epistemological objections concerning the rationality of moral belief. The first objection I deal with comes from Derek Baker and is directed against Mark Schroeder's specific development of expressivism. I deal with this objection because my own theory bears close resemblance to Schroeder's theory and so it might be worried that it confronts the same issues. Fortunately, we will see that Baker's objection rest on a number of mistaken assumptions and so neither applies to Schroeder's expressivism nor to the version which I defend in this study. The other epistemological objection to metaethical expressivism I deal with is Cian Dorr's famous wishful-thinking objection. In contrast to previous replies to this objection I attack it by directly questioning the central assumption on which it rests, namely that reasoners can never be justified in basing a factual belief on a desire-like state. I argue that this is false, and that under certain conditions reasoning from desire-like mental states to factual beliefs is justified. My argument shows that even if holding a moral belief is being in a desire-like noncognitive state, basing factual belief on a moral belief can give one an epistemic reason for the factual belief. Hence, even if moral thoughts are wishes, moral thinking is not wishful thinking. I take my arguments to earn the dispositional expressivist the right to moral belief. By the previously defended theory of truth-aptness in terms of belief, this allows the dispositional expressivists to conclude that moral sentences are also truth-apt. This finishes the quasi-realist project of this dissertation. In the last part of this dissertation I switch gears and present two unnoted problems for metaethical expressivists having to do with explaining moral motivation. Both arguments are surprisingly simple. The first one is this: if motivation requires a belief as well as a desire (Humeanism), and moral judgments motivate by themselves (internalism), then moral judgments cannot be desires only. If this argument is sound, it shows that the famous `motivation argument´ not only entails the falsity of cognitivism, but also the falsity of noncognitivism. The second argument is the following: moral judgments when combined with suitable external desires motivate to act (externalism), but if motivation requires belief as well as desire (Humeanism), then moral judgments cannot be desires only. I discuss several ways in which noncognitivists might want to deal with those problems, but leave it as an open question whether those solutions will ultimately be viable. Overall, this dissertation makes serious contributions to the research program of metaethical expressivism. It makes proposals for how to solve a number of notorious problems, such as the Frege-Geach problem in semantics and the wishful-thinking problem in epistemology. Besides this, however, it also raises two new problems for metaethical expressivism in the philosophy of action. For those reasons this dissertation will be of interest for anyone who wants to defend or criticize expressivism in metaethics, and more generally, anyone who wants to better understand our astonishing ability to express moral beliefs.

This paper presents some impossibility results for certain views about what you should do when you are uncertain about which moral theory is true. I show that under reasonable and extremely minimal ways of defining what a moral theory is, it follows that the concept of expected moral choiceworthiness is undefined, and more generally that any theory of decision-making under moral uncertainty must generate pathological results.

The term “altruism” is used in many ways. In this thesis, I discuss altruism as a motivation, which is an influential notion in philosophy and the social sciences. Questions about the nature and the possibility of altruistic motivation have inspired much debate, both in academia and in everyday conversations. How can we know when we are truly altruistic and when we are merely helping others as a means to some egoistic goal? Are humans even capable of genuine altruistic motivation or (...) are we always egoistic deep down? Before answering questions like these, however, we need to ask a more fundamental question: how should we define altruistic motivation? The standard account of altruistic motivation in the literature defines it as an ultimate desire to increase the welfare of others. The central claim I will argue for in this thesis is that this standard account is intrinsically flawed and should be abandoned. -/- The problem with the standard account of altruistic motivation, in short, is its reliance on the notion of “ultimate desire”, which is a limited and unfruitful way of conceptualizing altruistic motivation. The criticism I propose is based on an interdisciplinary analysis of many aspects of the standard account, discussing its philosophical basis, its use in scientific research, its historical development, and its relation to common sense and morality. -/- This thesis is divided into four parts, each composed of two chapters. Part I presents the many technical accounts of altruism present in the scientific literature, distinguishing the standard account of altruistic motivation from alternative accounts of altruism. I discuss the hypotheses of psychological altruism, which states that some of our ultimate desires aim to increase the welfare of others, and psychological egoism, which states that all of our ultimate desires are egoistic. In this first part, I discuss some of the central philosophical concepts underlying the standard account of altruistic motivation, showing their implications for the debate about psychological altruism. -/- Part II discusses the main arguments for the existence of altruistic motivation. I argue that the main arguments in the scientific literature fail in making a defense of psychological altruism and that the definition of altruistic motivation makes the solution to the debate on psychological altruism virtually impossible. I conclude that the standard account makes altruistic motivation an unverifiable and unfruitful notion for scientific research. -/- Part III discusses the history of altruism and egoism, focusing particularly on early modern philosophy. I argue that the modern accounts of altruism and egoism diverge from the contemporary standard account of altruistic motivation. Reading the debates in modern philosophy through the lens of psychological altruism and psychological egoism oversimplifies and impoverishes the modern debate. I argue that the standard account also fails in representing the original use of “altruism”, proposed by Auguste Comte. In this third part, I show how the use of the standard account of altruistic motivation cannot be based on its historical foundations. -/- Finally, Part IV addresses the normative character of altruism and discusses some alternative ways of conceptualizing altruism. I argue that the standard account of altruistic motivation does not reflect the ordinary use of the term “altruism” and fails in accounting for its normative character. As an alternative, I propose an alternative account of altruism, virtue altruism. I claim that this account better reflects the ordinary intuitions about altruism, accommodates the descriptive and normative dimensions of altruism, is at home with most of the historical accounts of altruism, and may promote the active promotion of altruistic actions.

This paper provides an exposition and defence of Lewis' theory of radical interpretation. The first part explains what Lewis' theory was; the second part explains what it wasn't, and in so doing addresses a number of common objections that arise as a result of widespread myths and misunderstandings about how Lewis' theory is supposed to work.

The paper explains how to integrate the knowledge-first approach to epistemology with the intellectualist thesis that knowing-how is a kind of knowing-that, with emphasis on their role in practical reasoning. One component of this integration is a belief-based account of desire.

There is a common demand that moral theory be 'practical', voiced both in- and outside of philosophy. Neo-Humeans, Kantian constitutivists and Aristotelian naturalists have all advocated the idea that my knowledge that I ought to do something must lead me to actually do it—an idea sometimes called the “practicality requirement” for moral theory. Some university administrators apply this idea in practice, when they force students who violate the code of conduct to complete classes in moral theory, hoping that the knowledge (...) obtained there would lead the student not to reoffend. I argue that the practicality requirement rests on a false understanding of the relation both between knowledge and motivation, focusing my critique on recent Aristotelian proposals. (shrink)

Many philosophers in the field of meta-ethics believe that rational degrees of confidence in moral judgments should have a probabilistic structure, in the same way as do rational degrees of belief. The current paper examines this position, termed “moral Bayesianism,” from an empirical point of view. To this end, we assessed the extent to which degrees of moral judgments obey the third axiom of the probability calculus, ifP(A∩B)=0thenP(A∪B)=P(A)+P(B), known as finite additivity, as compared to degrees of beliefs on the one (...) hand and degrees of desires on the other. Results generally converged to show that degrees of moral judgment are more similar to degrees of belief than to degrees of desire in this respect. This supports the adoption of a Bayesian approach to the study of moral judgments. To further support moral Bayesianism, we also demonstrated its predictive power. Finally, we discuss the relevancy of our results to the meta-ethical debate between moral cognitivists and moral non-cognitivists. (shrink)

'Knowledge and its Limits' starts its exposition of the knowledge-first approach to epistemology with a structural analogy between knowledge and action as the two key relations between mind and world (Williamson 2000: 1, 6-8). This chapter aims to reconsider the relation between knowledge and action, and refine the analogy.

In the last 70 years there has been an explosion of philosophical and theological work on the nature of virtue and the process of virtue formation. Yet philosophers and theologians have paid little attention to the phenomenon of temptation and its role in developing virtue. Indeed, little analytic work has been done on the nature of temptation. This study aims to fill this gap in moral philosophy and theology by offering an analytic moral conception of temptation and explicating its connection (...) to the development of virtue. This project deploys a new iteration of an older methodology of integrating philosophy and theology that may now appropriately be called “analytic moral theology.” In discerning the nature of temptation and its role in virtue formation, theological sources provide foundational guidance. Analytic moral philosophy provides illumination, coherence, and conceptual robustness to the theological foundation. The argument developed follows in the footsteps of John Hick’s soul-making theodicy by contending that the development of virtue requires a world that permits of experiences of temptation. This conclusion is substantiated by a close moral analysis of the nature of temptation that builds on key works done in philosophical moral psychology, philosophy of action, and philosophical theology. The emerging conceptualization of temptation is then compared and contrasted with the closely related moral phenomenon of akrasia and weakness of will, and finally interfaced with a neo- Aristotelian conception of virtue development. In the end, Thomas Aquinas’s understanding of infused virtue is employed as a theological test of the thesis and conditions the scope of the thesis. In light of this constructive analysis of the nature of temptation and its argument for temptation’s role in acquiring moral virtue, this project makes a contribution to philosophical Christian ethics.

David Lewis rejected consequentialism in ethics. However, two aspects of his meta-ethical views make it a challenge to see how consequentialism could be resisted. Lewis endorses a maximising conception of rationality, where to be rational is to maximise value of a certain sort; he appears to think it is possible to be both rational and moral; and yet he rejects conceptions of moral action as acting to maximise moral value. The second tension in Lewis's views arises from his meta-ethics. Lewis's (...) naturalisation of morality is in terms of a naturalised account of value, including moral value. Insofar as he offers a motivational story for moral judgements, it is one that goes via a motivational connection to value. Yet his anti-consequentialism seems to commit him to rejecting a story of moral action entirely in terms of pursuit of moral value. In both cases there are things to be said about how to weave these strands of Lewis's thought together. After setting out these two apparent tensions in Lewis's thought about ethics, the paper discusses what a Lewisian could best say about these puzzles. Lewisians do have a number of plausible options for dealing with the first challenge. While there are things a Lewisian could attempt to extend Lewis's moral naturalism in a way that could deal with the second challenge, it is harder to see how to do this in a satisfying way. Attention then turns to what Lewis said in his letters on these topics: on that basis, perhaps Lewis was close to being an agent-relative consequentialist after all. (shrink)

I argue that desire sometimes amounts to knowledge, in the same sense that belief sometimes amounts to knowledge. The argument rests on two assumptions: that goodness is the correctness condition for desire and that knowledge is apt mental representation. Desire that amounts to knowledge—or ‘conative knowledge’—is illustrated by cases in which someone knows the goodness of something despite not believing that it is good.

The distinction between propositional and doxastic justification is normally applied to belief. The goal of this paper is to apply the distinction to faith and hope. Before doing so, I discuss the nature of faith and hope, and how they contrast with belief—belief has no essential conative component, whereas faith and hope essentially involve the conative. I discuss implications this has for evaluating faith and hope, and apply this to the propositional/doxastic distinction. There are two key upshots. One, bringing in (...) faith and hope makes salient additional normative categories, including the way the distinction between epistemic and practical justification interacts with the distinction between propositional and doxastic justification. Two, a paradigm example of propositional without doxastic justification is a belief that is evidentially supported but based on wishful thinking. Surprisingly, parallel cases of faith and hope may actually enjoy both propositional and doxastic justification. I conclude by exploring what it might look like for faith and hope to have propositional justification without doxastic justification. (shrink)

Controversy about the credibility of normative realism is endemic to contemporary metaethics. Some take realism to be “obviously, the default position,” while others, to put it mildly, do not., In the face of such persistent controversy, it can be valuable to step back from the myriad arguments for and against realism, and seek to understand the challenges that face this view in their deepest and most general form. This paper aims to achieve this deeper understanding with respect to a pair (...) of familiar challenges to normative realism in the philosophy of mind. (shrink)

This paper argues that evidential decision theory is incompatible with options having objective values. If options have objective values, then it should always be rationally permissible for an agent to choose an option if they are certain that the option uniquely maximizes objective value. But, as we show, if options have objective values and evidential decision theory is true, then it is not always rationally permissible for an agent to choose an option if they are certain that the option uniquely (...) maximizes objective value.

Desires matter. What are desires? Many believe that desire is a motivational state: desiring is being disposed to act. This conception aligns with the functionalist approach to desire and the standard account of desire's role in explaining action. According to a second influential approach, however, desire is first and foremost an evaluation: desiring is representing something as good. After all, we seem to desire things under the guise of the good. Which understanding of desire is more accurate? Is the guise (...) of the good even right to assume? Should we adopt an alternative picture that emphasizes desire's deontic nature? What do neuroscientific studies suggest? -/- Essays in the first section of the volume are devoted to these questions, and to the puzzle of desire's essence. In the second part of the volume, essays investigate some implications that the various conceptions of desire have on a number of fundamental issues. For example, why are inconsistent desires problematic? What is desire's role in practical deliberation? How do we know what we want? -/- This volume will contribute to the emergence of a fruitful debate on a neglected, albeit crucial, dimension of the mind. (shrink)

On Hume’s account of motivation, beliefs and desires are very different kinds of propositional attitudes. Beliefs are cognitive attitudes, desires emotive ones. An agent’s belief in a proposition captures the weight he or she assigns to this proposition in his or her cognitive representation of the world. An agent’s desire for a proposition captures the degree to which he or she prefers its truth, motivating him or her to act accordingly. Although beliefs and desires are sometimes entangled, they play very (...) different roles in rational agency. In two classic papers (Lewis 1988, 1996), David Lewis discusses several challenges to this Humean picture, but ultimately rejects them. We think that his discussion of a central anti-Humean alternative – the desire-as-belief thesis – is in need of refinnement. On this thesis, the desire for proposition p is given by the belief that p is desirable. Lewis claims that ‘[e]xcept in trivial cases, [this thesis] collapses into contradiction’(Lewis 1996, p. 308). The problem, he argues, is that the thesis is inconsistent with the purportedly plausible requirement that one’s desire for a proposition should not change upon learning that the proposition is true; call this the invariance requirement. In this paper, we revisit Lewis’s argument. We show that, if one carefully distinguishes between non-evaluative and evaluative propositions, the desire-asbelief thesis can be rendered consistent with the invariance requirement. Lewis’s conclusion holds only under certain conditions: the desire-as-belief thesis conflicts with the invariance requirement if and only if there are certain correlations between non-evaluative and evaluative propositions. But when there are such correlations, we suggest, the invariance requirement loses its plausibility. Thus Lewis’s argument against the desire-as-belief thesis appears to be valid only in cases in which it is unsound. (shrink)

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

This paper has three interdependent aims. The first is to make Reichenbach’s views on induction and probabilities clearer, especially as they pertain to his pragmatic justification of induction. The second aim is to show how his view of pragmatic justification arises out of his commitment to extensional empiricism and moots the possibility of a non-pragmatic justification of induction. Finally, and most importantly, a formal decision-theoretic account of Reichenbach’s pragmatic justification is offered in terms both of the minimax principle and the (...) dominance principle.

Famous results by David Lewis show that plausible-sounding constraints on the probabilities of conditionals or evaluative claims lead to unacceptable results, by standard probabilistic reasoning. Existing presentations of these results rely on stronger assumptions than they really need. When we strip these arguments down to a minimal core, we can see both how certain replies miss the mark, and also how to devise parallel arguments for other domains, including epistemic “might,” probability claims, claims about comparative value, and so on. A (...) popular reply to Lewis's results is to claim that conditional claims, or claims about subjective value, lack truth conditions. For this strategy to have a chance of success, it needs to give up basic structural principles about how epistemic states can be updated—in a way that is strikingly parallel to the commitments of the project of dynamic semantics.

An important objection to preference-satisfaction theories of well-being is that these theories cannot make sense of interpersonal comparisons of well-being. A tradition dating back to Harsanyi () attempts to respond to this objection by appeal to so-called extended preferences: very roughly, preferences over situations whose description includes agents’ preferences. This paper examines the prospects for defending the preference-satisfaction theory via this extended preferences program. We argue that making conceptual sense of extended preferences is less problematic than others have supposed, but (...) that even so extended preferences do not provide a promising way for the preference satisfaction theorist to make interpersonal well-being comparisons. Our main objection takes the form of a trilemma: depending on how the theory based on extended preferences is developed, either the result will be inconsistent with ordinary preference-satisfaction theory, or it will fail to recover sufficiently rich interpersonal well-being comparisons, or it will take on a number of other arguably odd and undesirable commitments.

This article examines an allegedly Humean solution provided by J. Baird Callicott to the problem of the is/ought dichotomy. It also examines an allegedly Humean argument provided by him for the land ethic's summary moral precept. It concludes that neither the solution nor the argument is Humean or cogent.

Theses claiming a constitutive or necessary role for belief-desire pairs in the rationalizing, motivation or explanation of action, are generally known as Humean. The main purpose of this short paper is clearly to present the basic versions of Humeanism and lay bare their commitments and interrelations in preparation for a short general introduction to the debate over belief-desire explanation of action. After this, some influential arguments for and against a Humean account of action explanation are briefly discussed.

This paper has as its topic two recent philosophical disputes. One of these disputes is internal to the project known as decision theory, and while by now familiar to many, may well seem to be of pressing concern only to specialists. It has been carried on over the last twenty years or so, but by now the two opposing camps are pretty well entrenched in their respective positions, and the situation appears to many observers (as well as to some of (...) the parties involved) to have reached a sort of stalemate. The second of these two disputes is, on the other hand, very much alive. While it has been framed in decision theoretic terms, it is definitely not a dispute internal to that enterprise. It is, rather, a debate about the very coherence of the notion of objective value, and as such touches on issues of central importance to, for example, meta–ethics and moral psychology. (shrink)

According to one version of objectivism about value, ethical and other evaluative claims have a fixed truth-value independently of who makes them or the society in which they happen to live (c.f. Davidson 2004, 42). Subjectivists about value deny this claim. According to subjectivism so understood, ethical and other evaluative claims have no fixed truth-value, either because their truth-value is dependent on who makes them, or because they have no truth-value at all.

A classic, though basically neglected question about motivation arises when we attempt to account for blame’s nature—namely, does the recognition central to blame need help from an independent desire in order to motivate the blame-characteristic dispositions that arise in the blamer? Those who have attended to the question think the answer is yes. Hence, they adopt what I call a Humean Construal of blame on which blame is (a) a judgment that an individual S is blameworthy and (b) an independent (...) desire about S not doing as they did or being as they are. This paper rejects arguments for the Humean Construal, illustrates deep failings of that view, and uses these considerations to support anti-Humean accounts of blame in particular and moral motivation more broadly.

The Desire-as-Belief thesis (DAB) states that any rational person desires a proposition exactly to the degree that she believes or expects the proposition to be good. Many people take David Lewis to have shown the thesis to be inconsistent with Bayesian decision theory. However, as we show, Lewis's argument was based on an Invariance condition that itself is inconsistent with the (standard formulation of the) version of Bayesian decision theory that he assumed in his arguments against DAB. The aim of (...) this paper is to explore what impact the rejection of Invariance has on the DAB thesis. Without assuming Invariance, we first refute all versions of DAB that entail that there are only two levels of goodness. We next consider two theses according to which rational desires are intimately connected to expectations of (multi-levelled) goodness, and show that these are consistent with Bayesian decision theory as long as we assume that the contents of 'value propositions' are not fixed. We explain why this conclusion is independently plausible, and show how to construct such propositions. (shrink)

I present and defend (1) an account of ethical judgments as judgments about our reasons to feel specific motivationally laden attitudes, (2) an account of what an agent should do in terms of what would achieve ends that she has reason to be motivated to pursue, and (3) an account of an agent’s reasons for motivation (and thus action) in terms of the prescriptions of the most fundamental principles that guide her deliberations. Using these accounts, I explain the connection between (...) ethics and reasons for action, how ethical judgments are both descriptive and intrinsically motivating, and how ethical facts arise from facts about agents’ deliberations.

Evaluativism about desire, the view that desires just are, or necessarily involve, positive evaluations of their objects, currently enjoys widespread popularity in many philosophical circles. This chapter argues that evaluativism, in both of its doxastic and perceptual versions, overstates and mischaracterises the connection between desires and evaluations. Whereas doxastic evaluativism implausibly rules out cases where someone has a desire, despite evaluating its object negatively, being uncertain about its value, or having no doxastic attitude whatsoever towards its evaluative status at all, (...) perceptual evaluativism cannot even properly apply to the large class of standing desires. It is also argued that evaluativism about desire is not even well-motivated in the first place: the theory is supposed to solve a particular puzzle about the role desires play in the explanation of action, yet, in fact, it does not offer any help whatsoever in dealing with the relevant puzzle.

This paper examines the view that desires are beliefs about normative reasons for action. It describes the view, and briefly sketches three arguments for it. But the focus of the paper is defending the view from objections. The paper argues that the view is consistent with the distinction between the direction of fit of beliefs and desires, that it is consistent with the existence of appetites such as hunger, that it can account for counterexamples that aim to show that beliefs (...) about reasons are not sufficient for desire, such as weakness of will, and that it can account for counterexamples that aim to show that beliefs about reasons are not necessary for desire, such as addiction. The paper also shows how it is superior to the view that desires are appearances of the good. (shrink)

My dissertation addresses the question "do desires provide reasons?" I present two independent lines of argument in support of the conclusion that they do not. The first line of argument emerges from the way I circumscribe the concept of a desire. Complications aside, I conceive of a desire as a member of a family of attitudes that have imperative content, understood as content that displays doability-conditions rather than truth-conditions. Moreover, I hold that an attitude may provide reasons only if it (...) has truth-evaluable content. Insofar as desires lack truth-evaluable content, I hold that the content of a desire has the wrong kind of logical structure to provide reasons. My second line of argument claims that even if a desire did have truth-evaluable content, it would not follow that desires provide reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some attitude, A, for something that has rational significance, relative to A, and leave the rational standing of A unchanged. For example, one cannot substitute the guess that P (i.e., something that lacks rational significance relative to the belief that P) for the perception that P (i.e., something that is rationally significant relative to the belief that P) without altering the rational standing of the belief. I argue that when the non-substitutability principle is applied to a desire that gives rise to an intention, it turns out that one can always substitute a guess or coin-flip (i.e., something that lacks rational significance relative to the intention) for the desire, without altering the rational standing of the intention. I take this to show that desires are not rationally significant relative to the intentions to which they give. (shrink)

I show that David Lewis’s principal principle is not preserved under Jeffrey conditionalization.

Subjectivism about well-being holds that ϕ is intrinsically good for x if and only if, and to the extent that, ϕ is valued, under the proper conditions, by x. Given this statement of the view, there is room for intramural dissent among subjectivists. One important source of dispute is the phrase “under the proper conditions”: Should the proper conditions of valuing be actual or idealized? What sort of idealization is appropriate? And so forth. Though these concerns are of the first (...) importance, this essay focuses on a second source of dispute. As stated, subjectivists must account for what it means for an individual x to value ϕ under any conditions. Though there has been some disagreement, most subjectivists hold that x values ϕ if and only if x desires ϕ. This essay argues that subjectivists have erred in accepting a desiderative theory of valuing. Instead, it argues that subjectivists should hold that x values ϕ to the extent that x judges or believes that ϕ is good for x. The resulting “judgment subjectivism” is intuitively superior to, and maintains important structural advantages over, its desiderative rival. (shrink)

Many philosophers have become worried about the use of standard real numbers for the probability function that represents an agent's credences. They point out that real numbers can't capture the distinction between certain extremely unlikely events and genuinely impossible ones—they are both represented by credence 0, which violates a principle known as “regularity.” Following Skyrms 1980 and Lewis 1980, they recommend that we should instead use a much richer set of numbers, called the “hyperreals.” This essay argues that this popular (...) view is the result of two mistakes. The first mistake, which this essay calls the “numerical fallacy,” is to assume that a distinction that isn't represented by different numbers isn't represented at all in a mathematical representation. In this case, the essay claims that although the real numbers do not make all relevant distinctions, the full mathematical structure of a probability function does. The second mistake is that the hyperreals make too many distinctions. They have a much more complex structure than credences in ordinary propositions can have, so they make distinctions that don't exist among credences. While they might be useful for generating certain mathematical models, they will not appear in a faithful mathematical representation of credences of ordinary propositions. (shrink)

*These notes were folded into the published paper "Probability and nonclassical logic*. Revising semantics and logic has consequences for the theory of mind. Standard formal treatments of rational belief and desire make classical assumptions. If we are to challenge the presuppositions, we indicate what is kind of theory is going to take their place. Consider probability theory interpreted as an account of ideal partial belief. But if some propositions are neither true nor false, or are half true, or whatever—then it’s (...) far from clear that our degrees of belief in it and its negation should sum to 1, as classical probability theory requires (?, cf.). There are extant proposals in the literature for generalizing (categorical) probability theory to a non-classical setting, and we will use these below. But subjective probabilities themselves stand in functional relations to other mental states, and we need to trace the knock-on consequences of revisionism for this interrelationship (arguably, degrees of belief only count as kinds of belief in virtue of standing in these functional relationships).

Abstract The paper explicates a set of criteria the joint satisfaction of which is taken to qualify moral judgements as cognitive. The paper examines evidence that some moral judgements meet these criteria, and relates the resulting conception of moral judgements to ongoing controversies about cognitivism in ethics.

Can the question "Why do what morality requires?" be answered in such a way that anyone regardless of their desires or interests has reason to be moral? One strategy for answering this question appeals to constitutive arguments. In general, constitutive arguments attempt to establish the normativity of rational requirements by pointing out that we are already committed to them insofar as we are believers or agents. This study is concerned with the general prospects for such arguments. It starts by explaining (...) the general constitutive argument strategy, followed by an examination of constitutive arguments that have been given regarding theoretical reason and the instrumental principle in practical reason, and concluding with a discussion of some challenges to constitutive arguments in moral philosophy and some possible responses to these challenges.

To desire is to be in a particular state of mind. It is a state of mind familiar to everyone who has ever wanted to drink water or desired to know what has happened to an old friend, but its familiarity does not make it easy to give a theory of desire. Controversy immediately breaks out when asking whether wanting water and desiring knowledge are, at bottom, the same state of mind as others that seem somewhat similar: wishing never to (...) have been born, preferring mangoes to peaches, craving gin, having world conquest as one's goal, having a purpose in sneaking out to the shed, or being inclined to provoke just for the sake of provocation. These varied states of mind have all been grouped together under the heading of ‘pro attitudes’, but whether the pro attitudes are fundamentally one mental state or many is disputed. (shrink)

Bryne & Hajek (1997) argue that Lewis’s (1988; 1996) objections to identifying desire with belief do not go through if our notion of desire is ‘causalized’ (characterized by causal, rather than evidential, decision theory). I argue that versions of the argument go through on certain assumptions about the formulation of decision theory. There is one version of causal decision theory where the original arguments cannot be formulated—the ‘imaging’ formulation that Joyce (1999) advocates. But I argue this formulation is independently objectionable. (...) If we want to maintain the desire as belief thesis, there’s no shortcut through causalization. (shrink)

How can the propositional attitudes of several individuals be aggregated into overall collective propositional attitudes? Although there are large bodies of work on the aggregation of various special kinds of propositional attitudes, such as preferences, judgments, probabilities and utilities, the aggregation of propositional attitudes is seldom studied in full generality. In this paper, we seek to contribute to filling this gap in the literature. We sketch the ingredients of a general theory of propositional attitude aggregation and prove two new theorems. (...) Our first theorem simultaneously characterizes some prominent aggregation rules in the cases of probability, judgment and preference aggregation, including linear opinion pooling and Arrovian dictatorships. Our second theorem abstracts even further from the specific kinds of attitudes in question and describes the properties of a large class of aggregation rules applicable to a variety of belief-like attitudes. Our approach integrates some previously disconnected areas of investigation. (shrink)

In “Desire as Belief” and “Desire as Belief II,” David Lewis ( 1988 , 1996 ) considers the anti-Humean position that beliefs about the good require corresponding desires, which is his way of understanding the idea that beliefs about the good are capable of motivating behavior. He translates this anti-Humean claim into decision theoretic terms and demonstrates that it leads to absurdity and contradiction. As Ruth Weintraub ( 2007 ) has shown, Lewis’ argument goes awry at the outset. His decision (...) theoretic formulation of anti-Humeanism is one that no sensible anti-Humean would endorse. My aim is to demonstrate that Lewis’ infelicitous rendering of anti-Humeanism really does undermine the force of his arguments. To accomplish this, I begin by developing a more adequate decision theoretic rendering of the anti-Humean position. After showing that my formulation of anti-Humeanism constitutes a plausible interpretation of the anti-Humean thesis, I go on to demonstrate that if we adopt this more accurate rendition of anti-Humeanism, the view is no longer susceptible to arguments like the ones Lewis has devised. I thereby provide a more robust response to Lewis’ arguments than has yet been offered, and in the process I develop a formulation of anti-Humeanism that creates the possibility for future decision theoretic arguments that, unlike Lewis’, speak directly to the plausibility of anti-Humeanism.

I show the incompatibility of two theses: (a) to desire the truth of p amounts to believing a certain proposition about the value of p’s truth; (b) one cannot be said to desire the truth of p if one believes that p is true. Thesis (a), the Desire-As-Belief Thesis, has received much attention since the late 1980s. Thesis (b) is an epistemic variant of Socrates’ remark in the Symposium that one cannot desire what one already has. It turns out that (...) (a) and (b) cannot both be true if it is possible for there to exist an agent who has a desire initially, say the desire for the truth of p, and then expands the corpus of propositions she believes to include p. This result provides a new route to the denial of (a). (shrink)

The Humean theory of motivation remains the default position in much of the contemporary literature in meta-ethics, moral psychology, and action theory. Yet despite its widespread support, the theory is implausible as a view about what motivates agents to act. More specifically, my reasons for dissatisfaction with the Humean theory stem from its incompatibility with what I take to be a compelling model of the role of motivating reasons in first-person practical deliberation and third-person action explanations. So after first introducing (...) some assumptions about the nature of agency in section one, I will turn to articulating and defending this account of motivating reasons in sections two through four of the paper. Section five then provides some background on the Humean theory before I argue directly against it in section six and critically examine the leading arguments for the view in section seven. Given limitations of space, however, I save the task of developing a positive anti-Humean view for another occasion. (shrink)

There is a fairly widespread—and very infl uential—hope among philosophers interested in the status of normativity that the solution to our metaethical and, more generally, metanormative problems will emerge from the philosophy of action. In this essay, I will argue that these hopes are groundless. I will focus on the metanormative hope, but—as will become clear—showing that the solution to our metanormative problems will not come from what is constitutive of action will also devastate the hope of gaining significant insight (...) into first-order, normative truths by focusing on what is constitutive of action.

Metaethical questions are typically held to be a priori , and therefore impervious to empirical evidence. Here I examine the metaethical claim that motive-internalism about belief , the position that moral beliefs are intrinsically motivating, is true. I argue that belief-internalists are faced with a dilemma. Either their formulation of internalism is so weak that it fails to be philosophically interesting, or it is a substantive claim but can be shown to be empirically false. I then provide evidence for the (...) falsity of substantive belief-internalism. I describe a group of brain-damaged patients who sustain impairment in their moral sensibility: although they have normal moral beliefs and make moral judgments, they are not inclined to act in accordance with those beliefs and judgments. Thus, I argue that they are walking counterexamples to the substantive internalist claim. In addition to constraining our conception of moral reasoning, this argument stands as an example of how empirical evidence can be relevantly brought to bear on a philosophical question typically viewed to be a priori.

The paper explores the consequences of adopting a moral error theory targeted at the notion of reasonable convergence. I examine the prospects of two ways of combining acceptance of such a theory with continued acceptance of moral judgements in some form. On the first model, moral judgements are accepted as a pragmatically intelligible fiction. On the second model, moral judgements are made relative to a framework of assumptions with no claim to reasonable convergence on their behalf. I argue that the (...) latter model shows greater promise for an error theorist whose commitment to moral thought is initially serious. (shrink)
