Rationalizations of deliberation often make reference to two kinds of mental state, which we call belief and desire. It is worth asking whether these kinds are necessarily distinct, or whether it might be possible to construe desire as belief of a certain sort — belief, say, about what would be good. An expected value theory formalizes our notions of belief and desire, treating each as a matter of degree. In this context the thesis (...) that desire is belief might amount to the claim that the degree to which an agent desires any proposition A equals the degree to which the agent believes the proposition that A would be good. We shall write this latter proposition ‘A◦’ (pronounced ‘A halo’). The Desire-as-Belief Thesis states, then, that to each proposition A there corresponds another proposition A◦, where the probability of A◦ equals the expected value of A. (shrink)

In two curiously neglected papers, David Lewis claims to reduce to absurdity the supposition (commonly labeled DAB) that (some) desires are belief-like. My aim in this paper is to explain the significance of this claim and rebut the proof.

What is it to want something? Or, as philosophers might ask, what is a desire? This book defends “desire-as-belief”, the view that desires are just a special subset of our beliefs: normative beliefs. This view entitles us to accept orthodox models of human motivation and rationality that explain those things with reference to desire, but nonetheless to also make room for our normative beliefs to play a role in those domains. And this view tells us to (...) diverge from the orthodox view on which desires themselves can never be right or wrong. Rather, according to desire-as-belief, our desires can themselves be assessed for their accuracy, and they are wrong when they misrepresent normative features of the world. Hume says that it is not contrary to reason to prefer the destruction of the whole world to the scratching of your finger, but he is wrong: it is foolish to prefer the destruction of the whole world to the scratching of your finger, and this is foolish because this preference misrepresents the relative worth of these things.

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)

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)

Alex Gregory (2017a; 2017b; 2018; 2021) provides an ingenious, systematic defence of the view that desires are a species of belief about normative reasons. This view explains how desires make actions rationally intelligible. Its main rival, which is attractive for the same reason, says that desires involve a quasi-perceptual appearance of value. Gregory (2017a; 2018; 2021) has argued that his view provides the superior explanation of how desires are sensitive to evidence. Here, I show that the quasi-perceptual view fairs (...) better in this regard. Negatively, I argue that Gregory’s view overestimates the evidence-sensitivity of desires and implies that we are systematically mistaken in having different attitudes about desires and beliefs. Positively, I argue that quasi-perceptual appearances of value are brought into the scope of rational control through their dependence on prior representational states. I also provide a novel explanation of why some kinds of desires are resistant to rational control. I propose that desires are produced through exercises of an affective capacity to discriminate value. Variations in the way this capacity is exercised, and its links to prior representational states, can produce systematic insensitivity to evidence in certain kinds of desires. This paper advances the debate around desire on two fronts: first, it performs the neglected task of showing how the quasi-perceptual view can simultaneously explain both the sensitivity and insensitivity to evidence exhibited by desires and, second, it shows how the explanation offered is superior to one of its closest rivals, the view that desires are a species of normative belief.

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)

Argues for the humean theory of motivation on the grounds that rejecting it requires rejecting decision theory.

I show that David Lewis’s principal principle is not preserved under Jeffrey conditionalization. Using this observation, I argue that Lewis’s reason for rejecting the desire as belief thesis and Adams’s thesis applies also to his own principal principle. 1 Introduction2 Adams’s Thesis, the Desire as Belief Thesis, and the Principal Principle3 Jeffrey Conditionalization4 The Principal Principles Not Preserved under Jeffrey Conditionalization5 Inadmissible Experiences.

David Lewis describes, then attempts to refute, a simple anti-Humean theory of desire he calls ‘Desire as Belief’. Lewis’ critics generally accept that his argument is sound and focus instead on trying to show that its implications are less severe than appearances suggest. In this paper I argue that Lewis’ argument is unsound. I show that it rests on an essential assumption that can be straightforwardly proven false using ideas and principles to which Lewis is himself committed.

A traditional Humean view about motivation says that only desires motivate action. This theory meshes with the familiar ‘directions of fit’ metaphor: while beli.

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.

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)

David Lewis [1988; 1996] canvases an anti-Humean thesis about mental states: that the rational agent desires something to the extent that he or she believes it to be good. Lewis offers and refutes a decision-theoretic formulation of it, the 'Desire-as-Belief Thesis'. Other authors have since added further negative results in the spirit of Lewis's. We explore ways of being anti-Humean that evade all these negative results. We begin by providing background on evidential decision theory and on Lewis's negative (...) results. We then introduce what we call the indexicality loophole: if the goodness of a proposition is indexical, partly a function of an agent's mental state, then the negative results have no purchase. Thus we propose a variant of Desire-as-Belief that exploits this loophole. We argue that a number of meta-ethical positions are committed to just such indexicality. Indeed, we show that with one central sort of evaluative belief--the belief that an option is right--the indexicality loophole can be exploited in various interesting ways. Moreover, on some accounts, 'good' is indexical in the same way. Thus, it seems that the anti-Humean can dodge the negative results. (shrink)

Examines the desire‐belief‐theory, as presented, for example, in the work of Donald Davidson, which holds that a reason for which somebody does something is a combination of a desire and a belief of the agent. Widely accepted, this theory is seldom defended, the most explicit argument being due to Michael Smith. However, not only is his argument found wanting on a number of counts but the desire‐belief‐theory also gives desire and belief incompatible (...) roles to fulfill. Desire is asked both to set a goal and to provide the impulse for pursuing it, and, correspondingly, belief is held to give the agent guidance both in the sense of informing and in the sense of directing him or her.

On one influential view, a person acts autonomously, doing what she genuinely values, if she acts on a desire that is her own, which is (on this account) a matter of it being appropriately ratified at a higher level. This view faces two problems. It doesn’t generalize, as it should, to an account of when a belief is an agent’s own, and does not let one distinguish between desires (and beliefs) happening to be one's own and their being (...) the ones a person would need to have in order to be autonomous. The paper develops an alternative unified account of what it is for desires and beliefs to be one’s one, and argues that an account of acting autonomously should pay attention not to which desires and beliefs are one’s own, but to whether they are ones the agent has reason to have and to act on.

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)

Argumentation is a dialogical attempt to bring about a desired change in the beliefs of another agent – that is, to trigger a specific belief revision process in the mind of such agent. However, so far formal models of belief revision widely neglected any systematic comparison with argumentation theories, to the point that even the simplest argumentation structures cannot be captured within such models. In this essay, we endeavour to bring together argumentation and belief revision in the (...) same formal framework, and to highlight the important role played by Toulmin’s layout of argument in fostering such integration.

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 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. (shrink)

Deep appreciation of the relevance of emotion to epistemology requires a rich account of how emotional mental states such as happiness, sadness and desire interact with cognitive states such as belief and doubt. Analytic philosophy since Gottlob Frege and Bertrand Russell has assumed that such mental states are propositional attitudes, which are relations between a self and a proposition, an abstract entity constituting the meaning of a sentence. This chapter shows the explanatory defects of the doctrine of propositional (...) attitudes, and proposes instead that beliefs, desires, and emotions should be construed naturalistically using current understanding of brain mechanisms. Mental states are patterns of neural activity, not relations between dubious entities such as selves and propositions. From this perspective, it becomes easy to see how cognition and emotion are intertwined, and hence how emotions can be integral to epistemology. I begin by reviewing some of the ways in which emotions are relevant to epistemology: as frequent contributors to the growth of knowledge, as sometime impediments to knowledge acquisition, and as components of knowledge about persons and morality. I then argue that propositional attitudes do not exist, because the selves and the propositions that they purportedly relate do not exist. Thus the doctrine of propositional attitudes is as useless for epistemology as it is for explaining human action. I argue for an alternative construal of mental states as patterns of neural activity, and July 23, 2007 describe how it is possible to give a theoretically rich and empirically supported account of the neurophysiological interconnections of cognition and emotion. Finally, I discuss the epistemological significance of this naturalistic, materialist reconstrual of cognitions and emotions. (shrink)

The scheme of concepts we employ in daily life to explain intentional behaviour form a belief-desire model, in which motivating states are sorted into two suitably broad categories. The BD model embeds a philosophy of action, i.e. a set of assumptions about the ontology of motivation with subsequent restrictions on psychologising and norms of practical reason. A comprehensive critique of those assumptions and implications is offered in this work, and various criticisms of the model are met. The model’s (...) predictive and explanatory value exploits realistic notions of beliefs and desires as inner states underlying behavioural patterns. It is argued that the popular explication that beliefs and desires differ in their “direction of fit” is insufficient and inescapably normative. Essential to the model is the causal role given to desires. ‘Desire’ is therefore focussed. A dispositional and functional characterisation of desires is compatible with an eliminative view of dispositions. These views taken together do not exclude regarding desires as causes. Desires have propositional content. Content is a feature of desire’s dispositionality, and thereby causally relevant. This functional characterisation of content allows for non-linguistic content. The phenomenal conception of desire is criticised and diagnosed. A theme defended in various ways throughout the work is that desires mostly are unknown to agents and that the agent is in a less privileged position when it comes to analysis of his own motivational states, than e.g. people close to him. There are formal and empirical reasons to be pessimistic about agents’ abilities to make reliable predictions about their own intentional behaviour. The BD model’s concept of ‘intention’ is discussed and compared with non-reductive views of intentions. Criticisms of the common view that David Hume defends a BD model are presented, but it is argued that the BD interpretation of Hume is plausible, although this reading requires important qualifications in order to preserve internal consistency. The BD model leaves room for focussing attention, making foregrounded practical judgements, higher order desiring and other activities affecting one’s decision process. However, these various forms of deliberation in many cases are overrated. Three suggested norms of internal structural rationality are criticised in favour of simple Humean instrumentalism about practical reason. That position implies that criticism of other people’s ultimate ends is not a matter of internal rationality, but an inevitably social practice; it is dependent upon our concern for others, our view of their social roles and our own intrinsic desires.

This paper begins with an exposition the apparent tension between externalist theories of content and common-sense belief/desire psychology, with a view to resolving the conflict between these two views. The second part of the paper is a criticism of Fodor’s reformulation of Twin Earth type cases.I argue that this attempt to mitigate the damage such cases do to the tenability of folk psychological explanation cannot work, because Twin Earth cases pose a metaphysical problem for content and explanation, not (...) a nomological one, as Fodor argues. I discuss this in detail, by arguing that Twin Earth cases are illustrations of a metaphysical appearance/reality distinction for content.The paper concludes with a strategy for blending content externalism with a robust folk psychology: one that centers on the distinction between causation and causal explanation.

We adjudicate a recent dispute concerning the desire theory of well-being. Stock counterexamples to the desire theory include “quirky” desires that seem irrelevant to well-being, such as the desire to count blades of grass. Bruckner claims that such desires are relevant to well-being, provided that the desirer can characterize the object in such a way that makes it clear to others what attracts the desirer to it. Lin claims that merely being attracted to the object of one’s (...) desire should be sufficient for it to be relevant to one’s well-being. The capacity to characterize the desire as Bruckner requires does no work in the explanation of the welfare-relevance of the desire, Lin claims, especially since Lin’s account and Bruckner’s account are extensionally equivalent. In response, we provide a conceptual analysis of desire based on conceptual role semantics. Our analysis shows the plausibility of and motivation for Bruckner’s account. As well, it shows that the extensional equivalence of the accounts is no accident, but due to what it is to have a desire. Lin has not succeeded in providing an alternative to Bruckner’s account, but merely reformulated it, though in an illuminating way that supports Bruckner’s original case. (shrink)

The question why Bevir's account of intentionality is conceptualized purely in terms of individual beliefs is important as such a conceptualization appears to depart from standard accounts of intentionality within the philosophy of mind, that include reference to individual desires. It is beliefs and desires which are usually considered the rock?bottom components of individual intentional states, yet Bevir defines weak intentions solely in terms of the former while explicitly rejecting attention to the latter. There are a number of difficulties which (...) an account of meaning that excludes reference to desires faces. Nevertheless, there are a number of reasons for historians of ideas to embrace a theory of meaning that includes reference to beliefs but not desires. Through an extension of a different argument put forward by Bevir, it is suggested that such a belief?based definition of the nature of meaning is made defensible through reference to an account of the identity of the history of ideas as a discipline, a distinct area of academic enquiry that can be ? and for good reasons is ? individuated from the history of human action.

This paper argues that Donald Davidson''s account ofassertions of evaluative judgments contains ahere-to-fore unappreciated strategy forreconciling the meta-ethical ``inconsistenttriad.'''' The inconsistency is thought to resultbecause within the framework of thebelief-desire theory assertions of moraljudgments must have conceptual connections withboth desires and beliefs. The connection withdesires is necessary to account for theinternal connection between such judgments andmotivation to act, while the connection withbeliefs is necessary to account for theapparent objectivity of such judgments.Arguments abound that no class of utterancescan coherently be (...) understood as having suchconceptual connections to attitudes of bothsorts, hence that an inconsistency results. Buton Davidson''s account assertions of evaluativejudgments have just such connections to boththe relevant desire and a belief concerning anevaluative matter of fact. I argue that thisaccount has the resources to respond tostandard objections, and at least meritsconsideration as one among other plausiblealternatives. (shrink)

For many people, the phenomenon of divine hiddenness is so total that it is far from clear to them that God exists at all. Reasonably enough, they therefore do not believe that God exists. Yet it is possible, whilst lacking belief in God’s reality, nonetheless to see it as a possibility that is both realistic and attractive; and in this situation, one will likely want to be open to the considerable benefits that would be available if God were real. (...) In this paper I argue that certain kinds of desire for God can aid this non-believing openness. It is possible to desire God even in a state of non-belief, since desire does not require belief that its object exists. I argue that if we desire God in some particular capacity, and with some sense of what would constitute satisfaction, then through the desire we have knowledge -- incomplete yet vivid in its personal significance -- about the attributes God would need in order to satisfy us; thus, if God is real and does have those attributes, one knows something about God through desiring him. Because desire does not require belief, neither does the knowledge in question. Expanding on recent work by Vadas and Wynn, I sketch the epistemology of desire needed to support this argument. I then apply this epistemology to desire for God. An important question is how one might cultivate the requisite kinds desire for God; and one way, I argue, is through engaging with certain kinds of sacred music. I illustrate desire’s religiously epistemic power in this context, before replying to two objections. (shrink)

The belief-desire model of action explanation is deeply ingrained in multiple disciplines. There is reason to think that it is a cultural artifact. But is there an alternative? In this discussion, I will consider the radical critique of this action explanation model by Rüdiger Bittner, which argues that the model appeals to dubious mental entities, and argues for a model of reasons as responses to states or events. Instead, for Bittner, agents are reason-selectors—selecting the states or events to (...) respond to and selecting the ones the agent is disposed to respond to. By getting rid of the explanatory role of beliefs, this model runs into difficulties over errors usually attributed to false beliefs. These can be resolved by expanding the notion of dispositions to cover the case of false belief. But this suggests that the belief-reason model serves to divide the category of dispositions in an arbitrary or culturally specific way. (shrink)

In this article we take issue with theory theory and simulation theory accounts of folk psychology committed to (i) the belief-desire (BD) model and (ii) the assumption of universality (AU). Recent studies cast doubt on the compatibility of these commitments because they reveal considerable cross-cultural differences in folk psychologies. We present both theory theory and simulation theory with the following dilemma: either (i) keep the BD-model as an account of the surface properties of specific explicit folk psychologies and (...) give up AU in light of the cross-cultural evidence; or (ii) defend AU with respect to core capacities underlying different culture-specific folk psychologies, and explain why the BD-model will be genuinely explanatory at this level.

Whether rationalism when concerned with explanations of moral motivation should stand in opposition to the relevant Humean approach is a perplexing question that is oversimplified when reduced to a rationalism vs. Humeanism clear cut opposition about the possibility of rational control over desires.This paper criticizes the significance of this simplification as well as the hypothesis of unitary psychological states constituted by beliefs and desires (referred to as 'besires') and their alleged capacity to secure rational control over desires. Besires contribute in (...) the explanation of moral motivation only indirectly, that is, not as permanent unitary psychological states but only as relatively very short-term 'backgrounds' to subsequently detached matured desires.This interpretation further explored shows that the rational demandfor a genuine rational control over desires presupposes rather than opposing to the Humean belief desire distinctness - the latter actually securing the possibility of genuine moral incoherence as long as we intend to understand it neither as irrationality, nor as psychological deficiency.

Based on the belief that computational modeling (thinking in terms of representation and computations) can help to clarify controversial issues in emotion theory, this article examines emotional experience from the perspective of the Computational Belief–Desire Theory of Emotion (CBDTE), a computational explication of the belief–desire theory of emotion. It is argued that CBDTE provides plausible answers to central explanatory challenges posed by emotional experience, including: the phenomenal quality,intensity and object-directedness of emotional experience, the function of (...) emotional experience and its relation to cognition and motivation, and the relation between emotional experience and emotion. In addition, CBDTE avoids most objections that have been raised against cognitive theories of emotion. A remaining objection, that beliefs are not necessary for the emotions covered by CBDTE, is rejected as empirically unsupported. (shrink)

Is there a Moore ’s paradox in desire? I give a normative explanation of the epistemic irrationality, and hence absurdity, of Moorean belief that builds on Green and Williams’ normative account of absurdity. This explains why Moorean beliefs are normally irrational and thus absurd, while some Moorean beliefs are absurd without being irrational. Then I defend constructing a Moorean desire as the syntactic counterpart of a Moorean belief and distinguish it from a ‘Frankfurt’ conjunction of desires. (...) Next I discuss putative examples of rational and irrational desires, suggesting that there are norms of rational desire. Then I examine David Wall’s groundbreaking argument that Moorean desires are always unreasonable. Next I show against this that there are rational as well as irrational Moorean desires. Those that are irrational are also absurd, although there seem to be absurd desires that are not irrational. I conclude that certain norms of rational desire should 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 begin the paper by outlining one classic argument for the guise of the good: that we must think that desires represent their objects favourably in order to explain why they can make actions rational (Quinn 1995; Stampe 1987). But what exactly is the conclusion of this argument? Many have recently formulated the guise of the good as the view that desires are akin to perceptual appearances of the good (Oddie 2005; Stampe 1987; Tenenbaum 2007). But I argue that this (...) view fails to capitalize on the above argument, and that the argument is better understood as favouring a view on which desires are belief-like states. I finish by addressing some countervailing claims made by Avery Archer (2016). (shrink)

Richard Jeffrey regarded the version of Bayesian decision theory he floated in ‘The Logic of Decision’ and the idea of a probability kinematics—a generalisation of Bayesian conditioning to contexts in which the evidence is ‘uncertain’—as his two most important contributions to philosophy. This paper aims to connect them by developing kinematical models for the study of preference change and practical deliberation. Preference change is treated in a manner analogous to Jeffrey’s handling of belief change: not as mechanical outputs of (...) combinations of intrinsic desires plus information, but as a matter of judgement and of making up one’s mind. In the first section Jeffrey’s probability kinematics is motivated and extended to the treatment of changes in conditional belief. In the second, analogous kinematical models are developed for preference change and in particular belief-induced change that depends on an invariance condition for conditional preference. The two are the brought together in the last section in a tentative model of pratical deliberation. (shrink)

David Lewis has argued against the thesis he calls "Desire as Belief", claiming it is incompatible with the fundamentals of evidential decision theory. I show that the argument is unsound, and demonstrate that a version of desire as belief is compatible with a version of causal decision theory.

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. (shrink)

Behaviorally, children’s explicit theory of mind (ToM) proceeds in a progression of mental-state understandings: developmentally, children demonstrate accurate explicit desire-reasoning before accurate explicit belief-reasoning. Given its robust and cross-cultural nature, we hypothesize this progression may be paced in part by maturation/specialization of the brain. Neuroimaging research demonstrates that the right temporoparietal junction (TPJ) becomes increasingly selective for ToM reasoning as children age, and as their ToM improves. But this research has narrowly focused on beliefs or on undifferentiated mental-states. (...) A recent ERP study in children included a critical contrast to desire-reasoning, and demonstrated that right posterior potentials differentiated belief-reasoning from desire-reasoning. Taken together, the literature suggests that children’s desire-belief progression may be paced by specialization of the right TPJ for belief-reasoning specifically, beyond desire-reasoning. In the present study, we tested this hypothesis directly by examining children’s belief- and desire-reasoning using functional near-infrared spectroscopy in conjunction with structural magnetic resonance imaging to pinpoint brain activation in the right TPJ. Results showed greatest activation in the right TPJ for belief-reasoning, beyond desire-reasoning, and beyond non-mental reasoning (control). Findings replicate and critically extend prior ERP results, and provide clear evidence for a specific neural mechanism underlying children’s progression from understanding desires to understanding beliefs.

Although some psychoanalysts in the clinical field have criticised Žižek for corrupting Lacan’s teachings, through playing down the importance of the clinical, there is no doubt that Žižek’s scholarship and contribution to psychoanalysis displays mastery of Lacanian theory. Moreover, Žižek has applied this mastery to push theoretical ideas about the subject and social worlds, into public and intellectual debate. For Žižek, Lacan is a master from whom social knowledge as well as knowledge of the social is developed and critiqued. In (...) keeping with Žižek’s ontology, an examination of the intersection of belief with desire reveals the importance of a critical return to ideology that cannot be overlooked, particularly when examining how present social conditions structure an intersection of desire and belief. For Žižek, the contemporary subject believes now more than ever. Žižek positions modern social conditions together with the practices and organisations which maintain ideologies, as structuring the contours of belief. Capitalism, the supposed master of the 20th century, has presented as not so reliable. Might belief be the 21st century master, stepping in to support those ideological forces which intensify the scaffolding of a failing capitalist system? (shrink)

We commonly appeal to emotions to explain human behaviour: we seek comfort out of grief, we threaten someone in anger and we hide in fear. According to the standard Humean analysis, intentional action is always explained with reference to a belief-desire pair. According to recent consensus, however, emotions have independent motivating force apart from beliefs and desires, and supplant them when explaining emotional action. In this paper I provide a systematic framework for thinking about the motivational structure of (...) emotion and show how it is consistent with the Humean analysis.

Emotions therefore motivate actions through the belief-desire system instead of overriding it. (shrink)
