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.

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 …lling this gap in the literature. We sketch the ingredients of a general theory of propositional attitude aggregation and prove two new theorems. (...) Our …rst 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 speci…c 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)

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)

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.

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.

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.

I introduce a mathematical account of expectation based on a qualitative criterion of coherence for qualitative comparisons between gambles (or random quantities). The qualitative comparisons may be interpreted as an agent’s comparative preference judgments over options or more directly as an agent’s comparative expectation judgments over random quantities. The criterion of coherence is reminiscent of de Finetti’s quantitative criterion of coherence for betting, yet it does not impose an Archimedean condition on an agent’s comparative judgments, it does not require the (...) binary relation reflecting an agent’s comparative judgments to be reflexive, complete or even transitive, and it applies to an absolutely arbitrary collection of gambles, free of structural conditions (e.g., closure, measurability, etc.). Moreover, unlike de Finetti’s criterion of coherence, the qualitative criterion respects the principle of weak dominance, a standard of rational decision making that obliges an agent to reject a gamble that is possibly worse and certainly no better than another gamble available for choice. Despite these weak assumptions, I establish a qualitative analogue of de Finetti’s Fundamental Theorem of Prevision, from which it follows that any coherent system of comparative expectations can be extended to a weakly ordered coherent system of comparative expectations over any collection of gambles containing the initial set of gambles of interest. The extended weakly ordered coherent system of comparative expectations satisfies familiar additivity and scale invariance postulates (i.e., independence) when the extended collection forms a linear space. In the course of these developments, I recast de Finetti’s quantitative account of coherent prevision in the qualitative framework adopted in this article. I show that comparative previsions satisfy qualitative analogues of de Finetti’s famous bookmaking theorem and his Fundamental Theorem of Prevision.The results of this article complement those of another article (Pedersen, Strictly coherent preferences, no holds barred, Manuscript, 2013). I explain how those results entail that any coherent weakly ordered system of comparative expectations over a unital linear space can be represented by an expectation function taking values in a (possibly non-Archimedean) totally ordered field extension of the system of real numbers. The ordered field extension consists of formal power series in a single infinitesimal, a natural and economical representation that provides a relief map tracing numerical non-Archimedean features to qualitative non-Archimedean features.

Does the desirability of a proposition depend on whether it is true? Not according to the Invariance assumption, held by several notable philosophers. The Invariance assumption plays an important role in David Lewis’ famous arguments against the so-called Desire-as-Belief thesis (DAB), an anti-Humean thesis according to which a rational agent desires a proposition exactly to the degree that she believes the proposition to be desirable. But the assumption is of interest independently of Lewis’ arguments, for instance since both Richard Jeffrey (...) and James Joyce make the assumption (or, strictly speaking, accept a thesis that implies Invariance) in their influential books on decision theory. The main claim to be defended in this paper is that Invariance is incompatible with certain assumptions of decision theory. I show that the assumption fails on the most common interpretations of desirability and/or choice-worthiness found in decision theory. I moreover show that Invariance is inconsistent with Richard Jeffrey’s decision theory, on which Lewis’ arguments against DAB are based. Finally, I show that Invariance contradicts how we in general do and should think about conditional desirability. (shrink)

A key component of much current research in behavioral ecology, cognitive science, and economics is a model of the mind at least partly based on beliefs and desires. However, despite this prevalence, there are still many open questions concerning both the structure and the applicability of this model. This is especially so when it comes to its ‘desire’ part: in particular, it is not yet entirely clear when and why we should expect organisms to be desire-based—understood so as to imply (...) that they consult explicit tokenings of what they ought to do—as opposed to being drive-based—understood so as to imply that they react to the world using behavioral reflexes. In this paper, I present the beginnings of an answer to this question. To do this, I start by showing that an influential recent attempt to address these issues—due to Kim Sterelny—fails to be fully successful, as it does not make sufficiently clear what the relative benefits and disadvantages of drive-based and desire-based cognitive architectures are. I then present an alternative account of this matter based on the idea that organisms that can follow explicit behavioral rules (i.e. which have desires) avoid having to memorize a large set of state of the world–action connections—which can (though need not) be adaptive. Finally, I apply this account to the question of what the cognitive value of mental representations should be seen to be; here, I conclude that—contrary to some recent claims—relying on mental representations can make decision making easier, not harder, but also that—in line with these recent claims—whether it does so depends on the details of the case.

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.

This paper develops a novel puzzle about desire consisting of three independently plausible but jointly inconsistent propositions: all desires are dispositional states, we have privileged access to some of our desires, and we do not have privileged access to any dispositional state. Proponents of the view that all desires are dispositional states might think the most promising way out of this puzzle is to deny. I argue, however, that such attempts fail because the most plausible accounts of self-knowledge of desires (...) do not explain how we possess privileged access to dispositional desires. I conclude by offering what I take to be a more promising solution to the puzzle, one that involves the rejection of on the grounds that some desires possess phenomenology. (shrink)

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.

According to a widespread, broadly Humean consensus, desires and other conative attitudes seem as such to be free from any normative constraints of rationality. However, rational subjects are also required to be attitude-coherent in ways that prima facie hold sway for desire. I here examine the plausibility of this idea by proposing several principlesfor coherent desire. These principles parallel principles for coherent belief and can be used to make a case for a kind of purely conative normativity. I consider several (...) objections to a principle for consistent desiring and reply to them. I conclude that, if attitude-coherence is a mark of rationality, the broadly Humean consensus must be rejected. (shrink)

How many attitudes must be posited at the level of reductive bedrock in order to reductively explain all the rest? Motivational Humeans hold that at least two attitudes are indispensable, belief and desire. Desire-As-Belief theorists beg to differ. They hold that the belief attitude can do the all the work the desire attitude is supposed to do, because desires are in fact nothing but beliefs of a certain kind. If this is correct it has major implications both for the philosophy (...) of mind, with regards the problem of naturalizing the propositional attitudes, and for metaethics, with regards Michael Smith’s ‘moral problem’. This paper defends a version of Desire-As-Belief, and shows that it is immune to several major objections commonly levelled against such theories. (shrink)

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)

In contemporary philosophy, the will is often regarded as a sheer philosophical fiction. In Will as Commitment and Resolve , Davenport argues not only that the will is the central power of human agency that makes decisions and forms intentions but also that it includes the capacity to generate new motivation different in structure from prepurposive desires. The concept of "projective motivation" is the central innovation in Davenport's existential account of the everyday notion of striving will. Beginning with the contrast (...) between "eastern" and "western" attitudes toward assertive willing, Davenport traces the lineage of the idea of projective motivation from NeoPlatonic and Christian conceptions of divine motivation to Scotus, Kant, Marx, Arendt, and Levinas. Rich with historical detail, this book includes an extended examination of Platonic and Aristotelian eudaimonist theories of human motivation. Drawing on contemporary critiques of egoism, Davenport argues that happiness is primarily a byproduct of activities and pursuits aimed at other agent-transcending goods for their own sake. In particular, the motives involved in virtue and in its practice as understood by Alasdair MacIntyre are projective rather than eudaimonist. This theory is supported by analyses of radical evil, accounts of intrinsic motivation in existential psychology, and contemporary theories of identity-forming commitment in analytic moral psychology. Following Viktor Frankl, Joseph Raz, and others, Davenport argues that Harry Frankfurt's conception of caring requires objective values worth caring about, which serve as rational grounds for projecting new final ends. The argument concludes with a taxonomy of values or goods, devotion to which can make life meaningful for us. (shrink)

A triviality result for what Lewis called “the Desire by Necessity Thesis” and Broome : 265–267, 1991) called “the Desire as Expectation Thesis” is presented. The result shows that this thesis and three other reasonable conditions can be jointly satisfied only in trivial cases. Some meta-ethical implications of the result are discussed. The discussion also highlights several issues regarding Lewis ’ original triviality result for “the Desire as Belief Thesis” that have not been properly understood in the literature.

I examine a dispute about the nature of practical reason, and in particular moral reason, generated by Thomas Nagel's proposal of an internalist rationalism which claims we can explain motivation in terms of reason and belief alone. In opposition, Humeans contend that such explanations must also appeal to further desires. Arguments on either side of this debate typically assume that a rationalist or Humean conclusion can be reached independently of a claim about the nature of moral judgment. I'll maintain, to (...) the contrary, that a resolution of this dispute can only be achieved on the basis of such a claim. (shrink)

In this chapter, we critically examine the most important extant ways of understanding and motivating the idea that reasons for belief are normative. First, we examine the proposal that the distinction between explanatory and so-called normative reasons that is commonly drawn in moral philosophy can be rather straightforwardly applied to reasons for belief, and that reasons for belief are essentially normative precisely when they are normative reasons. In the course of this investigation, we explore the very nature of the reasons-for-belief (...) relation, as well as the ontology of such reasons. Second, we examine the idea that the normativity derives from the internal connection between reasons for belief and epistemic justification, distinguishing between two distinct normativist accounts of justification, a weaker and a stronger one. We argue that neither line of argument is compelling. Pending further arguments, we conclude that normativism about reasons for belief is not supported. (shrink)

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.
