This article argues that Lara Buchak’s risk-weighted expected utility (REU) theory fails to offer a true alternative to expected utility theory. Under commonly held assumptions about dynamic choice and the framing of decision problems, rational agents are guided by their attitudes to temporally extended courses of action. If so, REU theory makes approximately the same recommendations as expected utility theory. Being more permissive about dynamic choice or framing, however, undermines the theory’s claim to capturing a steady choice disposition in the (...) face of risk. I argue that this poses a challenge to alternatives to expected utility theory more generally. (shrink)

What is it to have a reason? According to one common idea, the "Factoring Account", you have a reason to do A when there is a reason for you to do A which you have--which is somehow in your possession or grasp. In this paper, I argue that this common idea is false. But though my arguments are based on the practical case, the implications of this are likely to be greatest in epistemology: for the pitfalls we fall into when (...) trying to defend the Factoring Account reflect very well the major developments in empiricist epistemology during the 20th century. I conjecture that this is because epistemologists have been--wrongly--wedded to the Factoring Account about evidence, which I conjecture is a certain kind of reason to believe. (shrink)

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) of the rationally permissible risk attitudes, is there some specific risk attitude that is required when choosing for others, or are we required to defer to the risk attitudes of the people on whose behalf we are choosing? This article elaborates on this question, explains its wider practical and theoretical significance, provides an overview of existing answers, and explores how to go about providing a more systematic account of how to choose on behalf of others in risky contexts.

Intentions matter. They have some kind of normative impact on our agency. Something goes wrong when an agent intends some end and fails to carry out the means she believes to be necessary for it, and something goes right when, intending the end, she adopts the means she thinks are required. This has even been claimed to be one of the only uncontroversial truths in ethical theory. But not only is there widespread disagreement about why this is so, there is (...) widespread disagreement about in what sense it is so. In this paper I explore an underdeveloped answer to the question of in what sense it is so, and argue that resolving an apparent difficulty with this view leads to an attractive picture about why it is so.

Reasons, it is often said, are king in contemporary normative theory. Some philosophers say not only that the vocabulary of reasons is useful, but that reasons play a fundamental explanatory role in normative theory—that many, most, or even all, other normative facts are grounded in facts about reasons. Even if reasons fundamentalism, the strongest version of this view, has only been wholeheartedly endorsed by a few philosophers, it has a kind of prominence in contemporary normative theory that suits it to (...) be described as orthodoxy by its critics. It is the purpose of this paper to make progress toward understanding what appeal Reasons Fundamentalism should have, and whether that appeal is deserved. I will do so by exploring and comparing two central motivations for Reasons Fundamentalism. (shrink)

Philosophers of science now broadly agree that doing good science involves making non-epistemic value judgments. I call attention to two very different normative standards which can be used to evaluate such judgments: standards grounded in ethics and standards grounded in political philosophy. Though this distinction has not previously been highlighted, I show that the values in science literature contain arguments of each type. I conclude by explaining why this distinction is important. Seeking to determine whether some value-laden determination meets substantive (...) ethical standards is a very different endeavor from seeking to determine if it is politically legitimate. (shrink)

Most philosophers find it puzzling how beliefs could wrong, and this leads them to conclude that they do not. So there is much philosophical work to be done in sorting out whether I am right to say that they do, as well as how this could be so. But in this paper I will take for granted that beliefs can wrong, and ask instead when beliefs wrong. My answer will be that beliefs wrong when they falsely diminish. This answer has (...) three parts: that beliefs wrong only when they are false, that beliefs wrong only when they diminish, and that false diminishment is sufficient for wronging. I will seek to elaborate on and defend all three of these claims, but it is the first to which I will give the most attention. (shrink)

Allow me to rehearse a familiar scenario. We all know that which ends you have has something to do with what you ought to do. If Ronnie is keen on dancing but Bradley can’t stand it, then the fact that there will be dancing at the party tonight affects what Ronnie and Bradley ought to do in different ways. In short, (HI) you ought, if you have the end, to take the means. But now trouble looms: what if you have (...) dreadful, murderous ends? Ought you to take the means to them? Seemingly not. But fortunately, an assumption made by deontic logics1 comes to the rescue. Since ‘‘ought’’, according to this assumption, is a sentential operator, HI must really be ambiguous. It could be read either as (Narrow) You have the end ! O(you take the means) or as (Wide) O(you have the end ! you take the means). Now if Narrow is true, then you really ought to take the means to your murderous ends. But this doesn’t follow from Wide. All that follows from Wide is that you ought to either take the means to these ends or else give them up. Conclusions: (1) Since HI is on some reading true, but Narrow isn’t, Wide is true. (2) Wide accounts for the relationship between your ends and what you ought to do. This elegant scenario repeats itself in many other domains in which it seems like something can have a bearing on what some particular agent ought to do. Does what you know affect what you ought to do? Do your beliefs about what you ought to do affect what you ought to do? Do your promises affect what you ought to do? Do your beliefs affect what you ought to believe? On each of these counts, the intuitive answer is ‘‘yes’’. And so each of these questions leaves something for the moral philosopher or the epistemologist to investigate. On each count, it seems that what we all know, is that (Account) you ought, if p, to do A. But on each count, the Narrow-scope reading of the ‘‘ought’’ in this claim yields unintuitive consequences. So since Account is true, it must be true on the Wide-scope reading.. (shrink)

According to a naïve view sometimes apparent in the writings of moral philosophers, ‘ought’ often expresses a relation between agents and actions – the relation that obtains between an agent and an action when that action is what that agent ought to do. It is not part of this naïve view that ‘ought’ always expresses this relation – on the contrary, adherents of the naïve view are happy to allow that ‘ought’ also has an epistemic sense, on which it means, (...) roughly, that some proposition is likely to be the case, and adherents of the naïve view are also typically happy to allow that ‘ought’ also has an evaluative sense, on which it means, roughly, that were things ideal, some proposition would be the case.1 What is important to the naïve view is not that these other senses of ‘ought’ do not exist, but rather that they are not exhaustive – for what they leave out, is the important deliberative sense of ‘ought’, which is the central subject of moral inquiry about what we ought to do and why – and it is this deliberative sense of ‘ought’ which the naïve view understands to express a relation between agents and actions.2 In contrast, logically and linguistically sophisticated philosophers – with a few notable exceptions3 – have rejected this naïve view. According to a dominant perspective in the interpretation of deontic logic and in linguistic semantics, for example, articulated by Roderick Chisholm (1964) and Bernard Williams (1981) in philosophy and in the dominant paradigm in linguistic semantics as articulated in particular by..

It is now generally understood that constraints play an important role in commonsense moral thinking and generally accepted that they cannot be accommodated by ordinary, traditional consequentialism. Some have seen this as the most conclusive evidence that consequentialism is hopelessly wrong,1 while others have seen it as the most conclusive evidence that moral common sense is hopelessly paradoxical.2 Fortunately, or so it is widely thought, in the last twenty-five years a new research program, that of Agent-Relative Teleology, has come to (...) the rescue on all sides. While consequentialism says that every agent ought always to do that action that will bring about the most good, according to Agent- Relative Teleology. (shrink)

Particularists in ethics emphasize that the normative is holistic, and invite us to infer with them that it therefore defies generalization. This has been supposed to present an obstacle to traditional moral theorizing, to have striking implications for moral epistemology and moral deliberation, and to rule out reductive theories of the normative, making it a bold and important thesis across the areas of normative theory, moral epistemology, moral psychology, and normative metaphysics. Though particularists emphasize the importance of the holism of (...) the normative, however, it is not something that they have been able to explain. In this paper I’ll show how to use a small number of simple and, I’ll argue, independently compelling assumptions in order to both predict and explain the holistic features of the normative with respect to the non-normative. The basic idea of the paper is simple. It is that normative claims are holistic because they are general, rather than because they defy generalization. (shrink)

Expressivists have a problem with negation. The problem is that they have not, to date, been able to explain why ‘murdering is wrong’ and ‘murdering is not wrong’ are inconsistent sentences. In this paper, I explain the nature of the problem, and why the best efforts of Gibbard, Dreier, and Horgan and Timmons don’t solve it. Then I show how to diagnose where the problem comes from, and consequently how it is possible for expressivists to solve it. Expressivists should accept (...) this solution, I argue, because it is demonstrably the only way of avoiding the problem, and because it generalizes. Once we see how to solve the negation problem, I show, it becomes easy to state a constructive, compositional expressivist semantics for a purely normative language with the expressive power of propositional logic, in which we can for the first time give explanatory, formally adequate expressivist accounts of logical inconsistency, logical entailment, and logical validity. As a corollary, I give what I take to be the first real expressivist explanation of why Geach’s original moral modus ponens argument is genuinely logically valid. This proves that the problem with expressivism cannot be that it can’t account for the logical properties of complex normative sentences. But it does not show that the same solution can work for a language with both normative and descriptive predicates, let alone that expressivists are able to deal with more complex linguistic constructions like tense, modals, or even quantifiers. In the final section, I show what kind of constraints the solution offered here would place expressivists under, in answering these further questions. (shrink)

The basic idea of expressivism is that for some sentences ‘P’, believing that P is not just a matter of having an ordinary descriptive belief. This is a way of capturing the idea that the meaning of some sentences either exceeds their factual/descriptive content or doesn’t consist in any particular factual/descriptive content at all, even in context. The paradigmatic application for expressivism is within metaethics, and holds that believing that stealing is wrong involves having some kind of desire-like attitude, with (...) world-tomind direction of fit, either in place of, or in addition to, being in a representational state of mind with mind-to-world direction of fit. Because expressivists refer to the state of believing that P as the state of mind ‘expressed’ by ‘P’, this view can also be described as the view that ‘stealing is wrong’ expresses a state of mind that involves a desire-like attitude instead of, or in addition to, a representational state of mind. According to some expressivists - unrestrained expressivists, as I’ll call them - there need be no special relationship among the different kinds of state of mind that can be expressed by sentences. Pick your favorite state of mind, the unrestrained expressivist allows, and there could, at least in principle, be a sentence that expressed it. Expressivists who seem to have been unrestrained plausibly include Ayer in Language, Truth, and Logic, and Simon Blackburn in many of his writings, including his [1984], [1993], and.. (shrink)

It doesn’t seem possible to be a realist about the traditional Christian God while claiming to be able to reduce God talk in naturalistically acceptable terms. Reduction, in this case, seems obviously eliminativist. Many philosophers seem to think that the same is true of the normative—that reductive “realists” about the normative are not really realists about the normative at all, or at least, only in some attenuated sense. This paper takes on the challenge of articulating what it is that makes (...) reductive theological realism look hopeless, with the aim of explaining why we should think that the normative is relevantly different. Although it follows from my diagnosis that reductivists have their work cut out for them, I find nothing which suggests that the prospects for a successful reductive realism about the normative are in any way diminished—particularly for reductive views about reasons. Even reductivists, I argue, can at least aspire to a realism that is robust. (shrink)

Fitting Attitudes accounts of value analogize or equate being good with being desirable, on the premise that ‘desirable’ means not, ‘able to be desired’, as Mill has been accused of mistakenly assuming, but ‘ought to be desired’, or something similar. The appeal of this idea is visible in the critical reaction to Mill, which generally goes along with his equation of ‘good’ with ‘desirable’ and only balks at the second step, and it crosses broad boundaries in terms of philosophers’ other (...) commitments. For example, Fitting Attitudes accounts play a central role both in T.M. Scanlon’s [1998] case against teleology, and in Michael Smith [2003], [unpublished] and Doug Portmore’s [2007] cases for it. And of course they have a long and distinguished history. (shrink)

In this paper I explore how and why personal identity might be essentially narrative in nature. My topic is the question of personal identity in the strict sense of identity—the question of which person you are, and how that person is extended in space, time, and quality. In this my question appears to contrast with the question of personal identity in the sense sought by teenagers and sufferers of mid-life crises who are trying to ‘find themselves’. But in fact it (...) will be key to my argument that these questions are not distinct and independent. Whereas Parfit was concerned, in his work on personal identity, with how he was extended over time, the teenager who is finding themselves is concerned with how they are extended in quality. Indeed, the core of my argument is that because narrative is the key to understanding how we are extended in quality, and quality is just one more dimension along which we are extended, along with space and time, narrative must also be the clue as to how we are extended in space and time. You, I will argue, are the protagonist in the best story of your life. (shrink)

Expressivism’s central idea is that normative sentences bear the same relation to non-cognitive attitudes that ordinary descriptive sentences bear to beliefs: the expression relation. Allan Gibbard teIls us that “that words express judgments will be accepted by almost everyone” - the distinctive contribution of expressivism, his claim goes, is only a view about what kind of judgments words express. But not every account of the expression relation is equally suitable for the expressivist’s purposes. In fact, what I argue in this (...) paper, considering four possible accounts of expression, is that how suitable each account is for the expressivist’s purpose varies in proportion to how controversial it is. So Gibbard is wrong - if expression is to get expressivism off the ground, then it will be enormously controversial whether words do express judgments. And thus expressivism is committed to strong claims about the semantics of non-normative language. (shrink)

This chapter lays out a case that with the proper perspective on the place of epistemology within normative inquiry more generally, it is possible to appreciate what was on the right track about some of the early approaches to the analysis of knowledge, and to improve on the obvious failures which led them to be rejected. Drawing on more general principles about reasons, their weight, and their relationship to justification, it offers answers to problems about defeat and the conditional fallacy (...) that plagued early defeasibility analyses of knowledge and offers a sketch of a contemporary alternative that is motivated by the idea that knowledge requires the right kind of “match” between objective and subjective factors.

There is a growing consensus among philosophers of science that core parts of the scientific process involve non-epistemic values. This undermines the traditional foundation for public trust in science. In this article I consider two proposals for justifying public trust in value-laden science. According to the first, scientists can promote trust by being transparent about their value choices. On the second, trust requires that the values of a scientist align with the values of an individual member of the public. I (...) argue that neither of these proposals work and suggest an alternative that does better. When scientists must appeal to values in the course of their research, they should appeal to democratic values: the values of the public or its representatives. (shrink)

Scientists are frequently called upon to “democratize” science, by bringing the public into scientific research. One appealing point for public involvement concerns the nonepistemic values involved in science. Suppose, though, a scientist invites the public to participate in making such value-laden determinations but finds that the public holds values the scientist considers morally unacceptable. Does the argument for democratizing science commit the scientist to accepting the public’s objectionable values, or may she veto them? I argue that there are a limited (...) set of cases in which scientists can, consistently with a commitment to democratized science, set aside the public’s judgments. (shrink)

According to the Book of Common Prayer, we have sinned against God “in thought, word, and deed.” In this paper I’ll explore one way of understanding what it might mean to sin against God in thought—the idea that we can at least potentially wrong God by what we believe. I will be interested in the philosophical tenability of this idea, and particularly in its potential consequences for the epistemology of religious belief and the problem of evil.

Scientists have the ability to influence policy in important ways through how they present their results. Surprisingly, existing codes of scientific ethics have little to say about such choices. I propose that we can arrive at a set of ethical guidelines to govern scientists’ presentation of information to policymakers by looking to bioethics: roughly, just as a clinician should aim to promote informed decision-making by patients, a scientist should aim to promote informed decision-making by policymakers. Though this may sound like (...) a natural proposal, I show it offers guidance that conflicts with standard scientific practices. I conclude by considering one cost of the proposal: that it would prevent scientists from acting as advocates in a way that is currently common in certain fields. I accept that the proposal would restrict scientists’ political advocacy rights, but argue that the benefits of adopting it — promoting democratic governance — justify the restriction. (shrink)

In the dynamic choice literature, temptations are usually understood as temporary shifts in an agent’s preferences. What has been puzzling about these cases is that, on the one hand, an agent seems to do better by her own lights if she does not give into the temptation, and does so without engaging in costly commitment strategies. This seems to indicate that it is instrumentally irrational for her to give into temptation. On the other hand, resisting temptation also requires her to (...) act contrary to the preferences she has at the time of temptation. But that seems to be instrumentally irrational as well. I here consider the two most prominent types of argument why resisting temptation could nevertheless be instrumentally rational, namely two-tier and intra-personal cooperation arguments. I establish that the arguments either fail or are redundant. In particular, the arguments fail under the pervasive assumption in both decision theory and the wider literature on practical rationality that the agent’s preferences over the objects of choice are themselves the standard of instrumental rationality. And they either still fail or they become redundant when we give up that assumption. (shrink)

This paper addresses the two extensional objections to the Humean Theory of Reasons—that it allows for too many reasons, and that it allows for too few. Although I won’t argue so here, manyof the other objections to the Humean Theoryof Reasons turn on assuming that it cannot successfully deal with these two objections.1 What I will argue, is that the force of the too many and the too few objections to the Humean Theorydepend on whether we assume that Humeans are (...) committed to a thesis about the weight of reasons—one I call Proportionalism. In particular, I’ll show how a version of the Humean Theorythat rejects Proportionalism can reasonablyhope to escape both the too many and the too few objections. This will constitute my defense of this version of the Humean Theory. But then, separately, I will argue that this defense of the Humean Theoryis not ad hoc. I’ll argue that Humeans have no reason to accept Proportionalism in the first place. Or at least, no weightyone. There are three parts to the paper. In Part 1 we introduce the Humean Theoryand the too few reasons objection. I’ll first layout the objection, and then layout the basis for a response on behalf of myfavored version of the Humean Theory. There will be an obvious objection to my defense— but it will turn out to depend on the assumption of Proportionalism. This will constitute myargument that the susceptibilityof the Humean Theoryto..

In the 1960s, Peter Geach and John Searle independently posed an important objection to the wide class of 'noncognitivist' metaethical views that had at that time been dominant and widely defended for a quarter of a century. The problems raised by that objection have come to be known in the literature as the Frege-Geach Problem, because of Geach's attribution of the objection to Frege's distinction between content and assertoric force, and the problem has since occupied a great deal of the (...) attention both of defenders of broadly noncognitivist views, and of their critics. In this article I explain Geach and Searle's historical objections, and put the subsequent discussion into dialectical context, paying some attention to the developments along the way and how they have enhanced our overall understanding of the problem. The article covers a lot of territory, so we will only be able to see the highlights, along the way. For further reading, see the Works Cited. (shrink)

In this paper I defend the view that knowledge is belief for reasons that are both objectively and subjectively sufficient from an important objection due to Daniel Whiting, in this journal. Whiting argues that this view fails to deal adequately with a familiar sort of counterexample to analyses of knowledge, fake barn cases. I accept Whiting’s conclusion that my earlier paper offered an inadequate treatment of fake barn cases, but defend a new account of basic perceptual reasons that is consistent (...) with the account of knowledge and successfully deals with fake barns.

Mainstream views of medical research tell us it should be a fact-based, value-free endeavor: what a scientist (or her funding source) wants or cares about should not influence her findings. At the same time, we also sometimes criticize medical research for failing to embody certain values, e.g. when we criticize pharmaceutical companies for largely ignoring the diseases that affect the global poor. This chapter seeks to reconcile these perspectives by distinguishing appropriate from inappropriate influences of values on medical research. It (...) divides this broad question into two narrower ones, the Role Question (at what points in the research process is value influence potentially acceptable?) and the Content Question (when value influence is potentially acceptable, what specific values should researchers use?), and then draws on the philosophical literature on values in science to explore answers to each of them.

This paper is a survey of recent ‘hybrid’ approaches to metaethics, according to which moral sentences, in some sense or other, express both beliefs and desires. I try to show what kinds of theoretical issues come up at the different choice points we encounter in developing such a view, to raise some problems and explain where they come from, and to begin to get a sense for what the payoff of such views can be, and what they will need to (...) do in order to earn that payoff.

Many economic measures are structured to reflect ethical values. I describe three attitudes towards this: maximalism, according to which we should aim to build all relevant values into measures; minimalism, according to which we should aim to keep values out of measures; and an intermediate view. I argue the intermediate view is likely correct, but existing versions are inadequate. In particular, economists have strong reason to structure measures to reflect fixed, as opposed to user-assessable, values. This implies that, despite disagreement (...) about precisely how to do so, economists should standardly adjust QALYs and DALYs to reflect egalitarian values. (shrink)

According to the standard view, Kant held that hypothetical imperatives are universally binding edicts with disjunctive objects: take-the-means-or-don't-have-the-end. But Kant thought otherwise. He held that they are edicts binding only on some - those who have an end.

Buck-passers about value accept two theses about value, a negative thesis and a positive. The negative thesis is that the fact that something is valuable is not itself a reason to promote or appreciate it. The positive thesis is that the fact that something is valuable consists in the fact that there are other reasons to promote or appreciate it. Buck-passers suppose that the negative thesis follows from the positive one, and sometimes insist on it as if it is the (...) central part of their view. But as I'll explain here, what we say about the negative thesis is orthogonal to what we say about the positive one. (shrink)

According to Part VI of Derek Parfit’s On What Matters, some things matter.1 Indeed, there are normative truths to the effect that some things matter, and it matters that there are such truths. Moreover, according to Parfit, these normative truths are cognitive and irreducible. And in addition to mattering that there are normative truths about what matters, Parfit holds that it also matters that these truths are cognitive and irreducible. Indeed this matters so much that Parfit tells us that if (...) there were normative truths, but that these truths were non-cognitive or reducible, then he, Sidgwick, and Ross “would have wasted much of our lives” [OWM2 367]. That it would be a consequence of the thesis either of noncognitivism or of reductive realism that Parfit would have wasted his life is, of course, no evidence against either thesis; it is perfectly possible even for the most brilliant thinkers to waste their lives. Indeed, as any of the students from my introductory ethics course would be quick to point out, it is very difficult to think clearly and objectively about a question in which you take yourself have a large personal stake. My undergraduates readily agree that the steak they have is enough to complicate their thinking about moral vegetarianism; so certainly explosive expressions like ‘wasted my life’ give Parfit the kind of loaded stake in metaethical questions that should make us cautious of trusting his intuitive verdicts in metaethics. Fortunately, as I will argue in this paper, Parfit has not wasted his life, and he would not have wasted his life, even if it turned out that either noncognitivism or reductive realism turned out to be true. In arguing that Parfit has not wasted his life, independently of the answer to any metaethical question, I am, of course, arguing against Parfit’s own conception of what makes his life worthwhile. Parfit clearly believes that the worthwhileness of [much of]2 his life turns on the answer to questions in metaethics.. (shrink)

This paper addresses the question: ‘what makes reasons sufficient?’ and offers the answer, ‘being at least as weighty as the reasons for the alternatives’. The paper starts by introducing some of the reasons why sufficiency has seemed difficult to understand, particularly in epistemology, and some circumstantial evidence that this has contributed to more general problems in the epistemological literature. It then introduces the positive account of sufficiency, and explains how this captures sufficiency in both the practical and epistemic domains. Finally, (...) the paper shows how once we understand the nature of sufficiency, it is easy to predict the full variety of ways in which rationality – both of action and of belief – can be defeated.

I compare two different arguments for the importance of bringing new voices into science: arguments for increasing the representation of women, and arguments for the inclusion of the public, or for “citizen science”. I suggest that in each case, diversifying science can improve the quality of scientific results in three distinct ways: epistemically, ethically, and politically. In the first two respects, the mechanisms are essentially the same. In the third respect, the mechanisms are importantly different. Though this might appear to (...) suggest a broad similarity between the cases, I show that the analysis reveals an important respect in which efforts to include the public are more complex. With citizen science programs, unlike with efforts to bring more women into science, the three types of improvement are often in conflict with one another: improvements along one dimension may come at a cost on another dimension, suggesting difficult trade-offs may need to be made.

The purpose of this paper is to conceptualize and explore what I shall call the Common Subject Problem for ethics. The problem is that there seems to be no good answer to what property everyone who makes moral claims could be talking and thinking about. The Common Subject Problem is not a new problem; on the contrary, I will argue that it is one of the central animating concerns in the history of both metaethics and normative theory. But despite its (...) importance, the Common Subject Problem is essentially invisible on many contemporary ways of carving up the problems of metaethics and normative ethical theory. My aim, therefore, is to make progress – in part by naming the problem, but also by beginning to sketch out the contours of what gives the problem its force, by distinguishing between different paths of response to the problem and assessing some of their chief merits, and finally, by distinguishing the Common Subject Problem from another problem with which it has come to be conflated. This nearby problem is the Moral Twin Earth Problem. Whereas the Common Subject Problem is a problem about what property ‘wrong’ could refer to, the Moral Twin Earth Problem is a problem about how ‘wrong’ could refer to it. The upshot of the paper, therefore, is to rescue one of the historically significant problems in normative ethics and metaethics – a problem that is essentially about normative semantics – from the illusion that has persisted over the last twenty years that it is really, somehow, a problem about metasemantics. Once we have reclaimed this problem, we can see that it could still be a problem even if there are no distinctively metasemantic problems in metaethics at all, that it is a problem faced by a wider variety of views, and that the space of possible solutions is much wider and more interesting for normative theory, moral psychology, and moral epistemology.

forthcoming in reisner and steglich-peterson, eds., Reasons for Belief If I believe, for no good reason, that P and I infer (correctly) from this that Q, I don’t think we want to say that I ‘have’ P as evidence for Q. Only things that I believe (or could believe) rationally, or perhaps, with justification, count as part of the evidence that I have. It seems to me that this is a good reason to include an epistemic acceptability constraint on evidence (...) possessed…1 It is a truism that adopting an unjustified belief does not put you in a better evidential position with respect to believing its consequences. This truism has led many philosophers to assume that there must, at a minimum, be a justification condition (and perhaps even a knowledge condition) on what it takes to count as having evidence. This is the best (or only) possible explanation of the truism, these philosophers have believed. This paper explores an alternative explanation for the truism. According to the alternative explanation that I will offer, unjustified beliefs do not put you in a better evidential position with respect to believing their consequences because any evidence you have in virtue of having an unjustified belief is guaranteed to be defeated. Since the lack of justification for a belief guarantees its defeat, I will suggest, we don't need to postulate a special justification condition (much less a knowledge condition) on what it takes to count as having evidence. Why is this important? It is important because the assumption that there must be a justification condition (or perhaps a knowledge condition) on what it takes to count as having evidence places a high bar on what it takes to have evidence - such a high bar that it is difficult to see how this bar could be met in the case of basic, perceptually justified beliefs. As a result, the high bar set by this condition plays a fundamental role, I will claim, in central features of a core dialectic from the epistemology of basic perceptual belief which plays a central role in the debates between internalism and externalism, foundationalism and coherentism, and rationalism and empiricism..

There is virtually no philosophical consensus on what, exactly, imperfect duties are. In this paper, I lay out three criteria which I argue any adequate account of imperfect duties should satisfy. Using beneficence as a leading example, I suggest that existing accounts of imperfect duties will have trouble meeting those criteria. I then propose a new approach: thinking of imperfect duties as duties held by groups, rather than individuals. I show, again using the example of beneficence, that this proposal can (...) satisfy the criteria, explaining how something can both have the necessity characteristic of duty, while also allowing agents the latitude which seems to attach to imperfect duties.

Douglas Portmore has recently argued in this journal for a "promising result" – that combining teleological ethics with "evaluator relativism" about the good allows an ethical theory to account for deontological intuitions while "accommodat[ing] the compelling idea that it is always permissible to bring about the best available state of affairs." I show that this result is false. It follows from the indexical semantics of evaluator relativism that Portmore's compelling idea is false. I also try to explain what might have (...) led to this misunderstanding. (shrink)

The last few decades have given rise to the study of practical reason as a legitimate subfield of philosophy in its own right, concerned with the nature of practical rationality, its relationship to theoretical rationality, and the explanatory relationship between reasons, rationality, and agency in general. Among the most central of the topics whose blossoming study has shaped this field, is the nature and structure of instrumental rationality, the topic to which Kant has to date made perhaps the largest contribution, (...) under the heading of his treatment of hypothetical imperatives.

This paper argues that instrumental rationality is more permissive than expected utility theory. The most compelling instrumentalist argument in favour of separability, its core requirement, is that agents with non-separable preferences end up badly off by their own lights in some dynamic choice problems. I argue that once we focus on the question of whether agents’ attitudes to uncertain prospects help define their ends in their own right, or instead only assign instrumental value in virtue of the outcomes they may (...) lead to, we see that the argument must fail. Either attitudes to prospects assign non-instrumental value in their own right, in which case we cannot establish the irrationality of the dynamic choice behaviour of agents with non-separable preferences. Or they don’t, in which case agents with non-separable preferences can avoid the problematic choice behaviour without adopting separable preferences. (shrink)

Standard decision theory, or rational choice theory, is often interpreted to be a theory of instrumental rationality. This dissertation argues, however, that the core requirements of orthodox decision theory cannot be defended as general requirements of instrumental rationality. Instead, I argue that these requirements can only be instrumentally justified to agents who have a desire to have choice dispositions that are stable over time and across different choice contexts. Past attempts at making instrumentalist arguments for the core requirements of decision (...) theory fail due to a pervasive assumption in decision theory, namely the assumption that the agent’s preferences over the objects of choice – be it outcomes or uncertain prospects – form the standard of instrumental rationality against which the agent’s actions are evaluated. I argue that we should instead take more basic desires to be the standard of instrumental rationality. But unless agents have a desire to have stable choice dispositions, according to this standard, instrumental rationality turns out to be more permissive than orthodox decision theory. (shrink)
