As debate continues around the nature and values of education, it is important to ask the question of what factors motivate a student to engage with the ends of an educational institution. In this paper, a broad, holistic view of learner motivation, derived from Aristotelian ethics, is used to provide a model to drive institutional change. Focussing on the approach of one Higher Education institution to the particular accommodations required for students with disabilities, the paper identifies three factors which (...) motivate students, a failure to engage with the aims and ends of the educational project, a failure to see that a particular learning aim is worth attaining, and a simple lack of will‐power to attain it. To each of these failures a social cause is identified, and a change in both the institutional culture and the individual learner's approach to their education is suggested. (shrink)

This essay defends a strong version of the Humean theory of motivation on which desire is necessary both for motivation and for reasoning that changes our desires. Those who hold that moral judgments are beliefs with intrinsic motivational force need to oppose this view, and many of them have proposed counterexamples to it. Using a novel account of desire, this essay handles the proposed counterexamples in a way that shows the superiority of the Humean theory. The (...) essay addresses the classic objection that the Humean theory cannot explain the feeling of obligation, Stephen Darwall's example of motivationally potent reasoning that is not based on preexisting desires, Thomas Scanlon's criticism that the Humean theory fails to account for the structure and phenomenology of deliberation, and the phenomenon of akrasia as discussed by John Searle. In each case a Humean account explains the data at least as thoroughly as opposing views can, while fitting within a simpler total account of how we deliberate and act. (shrink)

On the basis of 3p9s and 3p39s of the Ethics, it might seem that, for Spinoza, a judgment about something's goodness or badness is motivationally inert and, moreover, that value judgments essentially reflect an individual's pre-existing motivational states. However, in this paper I show that Spinoza holds that under certain conditions a motivational state results from a value judgment. Spinoza's theory of motivation consists of two accounts of the psychological order of value judgments and motivational states: an account (...) of their order in those in bondage as well as an account of their order in those who are free.

To vindicate morality against skeptical doubts, Kant must show that agents can be moved to act independently of their sensible desires. Kant must therefore answer a motivational question: how does an agent get from the cognition that she ought to act morally to acting morally? Affectivist interpretations of Kant hold that agents are moved to act by feelings, while intellectualists appeal to cognition alone. To overcome the significant shortcomings of each view, I develop a hybrid theory of motivation. (...) My central interpretive claim is that Kant is a special kind of motivational internalist: on his view, agents are moved to act by a feeling of intellectual pleasure at the prospect of accomplishing a task they have set for themselves, a feeling that originates in free choice. The resulting theory is immune to the challenges facing intellectualism and affectivism, thus strengthening the prospects of Kant’s justification of morality. (shrink)

It is clear that Kant's theory of motivation plays a central role in his ethical theory as a whole. Nevertheless, it has been subjected to many interpretations: (i) the 'orthodox' interpretation, (ii) the 'Aristotelian' or 'Humean' interpretation and (iii) the 'rationalist' interpretation. The first part of the thesis aims to provide an interpretation of Kant's theory of rational agency and motivation. I argue that the 'orthodox' and 'Aristotelian' interpretations should be rejected because they are incompatible (...) with Kant's conception of freedom, defending an account of Kant's position that goes along the lines of the rationalist interpretation. I show that Kant's theory of motivation is committed to a form of cognitivism, that is, the cognitive aspects of a motive are always the active factors in motivation. In Kant's terminology, the motives are provided by the agent's maxims, which express the reasons from which the agent acts. This part of the thesis examines Kant's theory of imperatives and his theory of motivation for cases of permissible, moral and immoral action. I conclude that in Kant's system, three levels of moral assessment can be distinguished: (i) rightness, (ii) moral worth, and (iii) virtue. However, my interest in Kant's theory is not merely exegetical; thus, the second aim of the thesis is to place Kant's position within the context of the following contemporary debates in metaethics: (i) debates about the relation between moral judgement and motivation, and (ii) debates about the nature of reasons for action, arguing that the Kantian position still represents an attractive philosophical view today. In relation to (i), I argue that Kant is committed to a form of motivational internalism, reconstruct Kant's argument for this view and reply to some possible externalist objections. In relation to (ii), I claim that since Kant's conception of reasons, based on the concept of maxims, differs from an internal conception of reasons (i.e., a conception that identifies reasons with the agent's desires), and from an external conception of reasons (i.e., a conception of reasons that identifies reasons with facts of the agent's situation), the term volitionism should be reserved to describe Kant's position.

According to the anti-Humean theory of motivation, it is possible to be motivated to act by reason alone. According to the Humean theory of motivation, this is impossible. The debate between these two theories remains as vigorous as ever (see for example Pettit 1987, Lewis 1988, Price 1989 and Smith 1994). In this paper I shall argue that the anti-Humean theory of motivation is incompatible with a number of prominent recent theories of content. I (...) shall focus on causal or informational theories of content (such as Dretske 1981, Fodor 1990 and Stalnaker 1984), and on verificationist theories of content (such as Dummett 1993, Putnam 1983 and Wright 1986), though in fact I believe that the same argument applies to several other theories of content as well.

Many philosophers today approach important psychological phenomena, such as weakness of the will and moral motivation, using a broadly Humean distinction between beliefs, which aim to represent the world, and desires, which aim to change the world. On this picture, desires provide the ends or goals of action, while beliefs simply tell us how to achieve those ends. In the Republic, Socrates attempts to explain the phenomena using a different distinction: he argues that the human soul or psyche consists (...) in reason, spirit, and appetite. It is initially tempting to assimilate Socrates’ picture to the standard belief ⁄ desire model, and to think that reason’s role in motivating action is restricted to calculating the best means for satisfying spirited and appetitive desires. But this would be a mistake, since Socrates thinks that each element in the soul is capable of setting the ends of action. But then how exactly should we understand these elements? My aim in this essay is to introduce the reader to Plato’s theory of the tripartite psychology. In part 2, I present Socrates’ argument for the claim that the soul has three elements. In part 3, I provide a general characterization of reason, spirit, and appetite, respectively. I then turn to discuss two central interpretive issues. In part 4, I discuss the sense in which Socrates considers the appetitive and spirited elements to be non-rational. And in the final part of the essay, I discuss the issue of how we ought to conceive of the parts of the soul, and more specifically, whether we should think of them as agent-like parts, or in some other way.

According to the Humean theory of motivation, desire is identified as the primary source of motivation, while cognitive states like beliefs are recognized as necessary but not sufficient conditions. This paper conducts a comprehensive analysis of the established teleological argument supporting the Humean theory of motivation. The analysis finds that recent anti-Humean strategies cannot conclusively challenge the core premises of this argument. While this result may initially imply a strong and convincing defense of the Humean (...) theory against opponents’ criticisms, it will be shown that the argument can withstand objections only through the adoption of an assumption that renders it unfalsifiable.

In this paper I will argue that the latter group [of Non-Humeans] is correct. My argument focuses on practical deliberation and has two parts. I will discuss two different problems that arise for the Humean Theory and suggest that while taken individually each problem appears to have a solution, for each problem the solution Humeans offer precludes solving the other problem. I will suggest that to see these difficulties we must take seriously the thought that we can only understand (...) an agent’s reasons for her action by looking at her actual or possible practical deliberation.

In lieu of an abstract, here is a brief excerpt of the content:163 HUME'S THEORY OF MOTIVATION In this paper I shall defend a Humean theory of motivation. But first I should like to examine some of the standard criticisms of this theory and some alternative views that are currently in favour. Both in the Treatise and the Enguiry Hume maintains that reason alone never motivates action but always requires the cooperation of some separate, and (...) separately identifiable desire-factor in order to bring about action. What are Hume's grounds for this view? In the Treatise. Hume writes: 'Tis obvious, that when we have the prospect of pain or pleasure from any object, we feel a consequent emotion of aversion or propensity, and are carry 'd to avoid or embrace what will give us this uneasiness or satisfaction.... 'Tis from the prospect of pleasure or pain that the aversion or propensity arises towards any object.... This passage suggests that the way we (and Hume) know about the presence of the separate desire factor which he claims is always needed to motivate our every purposive action is by being directly aware of some desire-feeling, by introspection, each and every time we act. There is however a familiar objection to this argument: no doubt we sometimes are aware of a feeling of desire when we act, e.g., in cases where we are motivated by strong emotions. But much of the time when we act calmly or casually, after having deliberated 'in a cool hour', or when performing routine and trivial acts, we are not directly aware of any desire-feeling at the time of action. 164 Hume is not unaware of this objection -- in reply to it he invokes his notorious doctrine of the calm passions. He writes: 'Tis natural for one, that does not examine objects with a strict philosophic eye, to imagine, that those actions of the mind are entirely the same, which produce not a different sensation, and are not immediately distinguishable to the feeling and perception. Reason, for instance, exerts itself without producing any sensible emotion; and except in the more sublime disquisitions of philosophy, or in the frivolous subtilities of the schools, scarce ever conveys any pleasure or uneasiness. Hence it proceeds, that every action of the mind, which operates with the same calmness and tranquillity, is confounded with reason by all those, who judge of things from the first view and appearance. Now 'tis certain, there are certain calm desires and tendencies, which, tho' they be real passions, produce little emotion in the mind, and are more known by their effects than by the immediate feeling or sensation. These desires are of two kinds; either certain instincts originally implanted in our natures, such as benevolence and resentment, the love of life, and kindness to children; or the general appetite to good, and aversion to evil, consider 'd merely as such. When any of these passions are calm, and cause no disorder in the soul, they are very readily taken for the determination of reason, and are suppos'd to proceed from the same faculty, with that, which judges of truth and falshood. Their nature and principles have been suppos'd the same, because their sensations are not evidently different. (T 417) The most obvious application of this argument would be to cases of cool, seemingly passionless 165 deliberation: e.g., in the course of planning the family budget I set aside funds for the children's education. A cursory inspection (or recollection) of the contents of my conscious mind at the time of acting would reveal to me some purely rational considerations that I had in mind at the time. I had some thoughts at the time whose contents are (roughly) expressible in such words as "If I don't put aside so much per month over so many years we will never be able to see them all through university." But cursory introspection or recollection would not detect any separately identifiable desire-factor present to my conscious mind at the time. Considered philosophical examination, Hume assures us, will reveal one, a 'calm' one -- in this case calm 'kindness to children'. Less obviously, the calm-passions argument, most naturally applicable to cases of deliberation... (shrink)

In this paper I propose minimal criteria for a successful theory of the mechanisms of motivation, and argue that extant philosophical accounts fail to meet them. Further, I argue that a predictive processing framework gives us the theoretical power to meet these criteria, and thus ought to be preferred over existing theories. The argument proceeds as follows—motivational mental states are generally understood as mental states with the power to initiate, guide, and control action, though few existing theories of (...) motivation explicitly detail how they are meant to explain these functions. I survey two contemporary theories of motivational mental states, due to Wayne Wu and Bence Nanay, and argue that they fail to satisfactorily explain one or more of these functions. Nevertheless, I argue that together, they are capable of giving a strong account of the control function, which competing theories ought to preserve. I then go on to argue that what I call the ‘predictive theory’ of motivational mental states, which makes use of the notion of active inference, is able to explain all three of the key functions and preserves the central insights of Wu and Nanay on control. It thus represents a significant step forward in the contemporary debate. (shrink)

This paper develops a model of individual decision-making under bounded rationality in which discretionary cognitive adjustment creates a durable stock that complements choice of action. While it increases utility, adjustment also entails a cost, because focusing attention optimally is effortful and mental resources are scarce. Associated behavioral phenomena are categorized based on whether the operative motivation in adjusting is forward-looking utility maximization or justification of prior action. The theory is in line with prior conceptions of cognitive dissonance, but (...) also offers a more empirically consistent explanation of the endowment effect, persuasive advertising, and sunk-cost effects than existing accounts.

In lieu of an abstract, here is a brief excerpt of the content:Hume's Theory ofMotivation — Part 2 Daniel Shaw Introduction and Summary of Part 1 In an earlier paper of the same title1 1 defended a Humean theory of motivation against rationalist views ofB. Stroud and T. Nagel.2 In this paper I shouldlike to relate my theory tomore recent writings, explain its implications for the topic ofmoral motivation and provide further support for the main (...) argument ofmy original paper. To begin with, a summary of my previous discussion: while two critics of Hume's theory, B. Stroud and T. Nagel, disagree about the role ofreason inaction(Stroudaccepts, Nagelrejectsthe Humeanclaim thatreason alone can never produce action) theyboth agree inrejecting Hume's view thatmotivating desire essentially involves feelings which are identifiable by the agent, in his conscious experience, by introspection, as something extra, something over and above any purely rational considerations he may have for taking action. As an alternative to this Humean, experiential view ofmotivating desire, Stroud argues that the concept of motivating desire should be analysednotinterms ofanyintrinsic propertyknowablein experience, butratherin terms ofits function in leading, along withbelief, to action. In Stroud's words: "It might well be that to have a desire for or a propensity towards E is simply to be in a state such that when you come to believe that a certain action will lead to E you are moved to perform that action."3 In a similar spirit4 Nagel claims, contrary to Hume, that there do exist at least some cases (for example, actions motivated by a person's prudential consideration of his own future interests) in which reason alone—that is, the agent's grasp of certain purely rational considerations—is all that motivates action. In the context of these purely rationally motivated actions, Nagel argues, our talk of desire does not refef to anyadditional inclination towards, or preferences for, or sentiment about some goal that we have, but is either just another way of saying that the act is motivated, that is, that we are in some state which disposes us to do whatever we think will lead to a certain result, or else indicates some structural feature ofthe reasoningbehind our behaviour; for example, indicates the fact that in view of purely rational considerations which confront us, it would be irrational of us not to perform the act in question. Volume XVII Number 2 19 DANIEL SHAW Against any such account ofmotivating desire which denies the necessity of the experiential component (that is, of Hume's introspectible sentiment), I argued that all such accounts have a false implication. They all falsely imply that some purely rational consideration, a bare behef, could, all on its own (unaccompanied by any actual or potential pro- or con-attitude), motivate a purposive action. With the help ofa counter-example I argued5 that although it is logically possible for bare beliefs of that kind to produce overt behaviour, such pure rationalist 'action' never in fact happens; and, more importantly, ifwe carefully consider what such 'action' would be like ifit didhappen, we findit would not count as voluntary, purposive action, in the fullest sense. So Hume, I concluded, was right to maintain that motivating desire essentially involves introspectible feehngs. However, the standard interpretation of Hume's view about the relation between desires and feelings yields an indefensible theory of motivated action. On the standard reading, desires simply are feehngs, and the Humean is left with no adequate reply to the obvious objection that, often enough, for example, when acting after calm deliberation, or when performing routine habit-actions, we are not aware of the occurrence of any such feehng immediately prior to or at the time of action. Hume tells us that in all such cases there is—in addition to the operation of reason—a calm passion present—a passion so calm as to be readily confused with and mistaken for the determinations of reason. But on the standard reading of 'calm passions' as very faint or imperceptible feelings, this is a lame argument. As Stroud points out,6 not only is there no independent justification for the claim that in all such cases there always are such faint or imperceptible feehngs,7 but also that claim is inconsistent...

What motivates behavior? What are the qualities of experience which make life worth living? Taking a new interdisciplinary approach, Morillo advances the theory that pleasure—interpreted as a distinct, separable, noncognitive quality of experience—is essential for all positive motivation and is the only intrinsic, nonmoral good in the lives of human beings and many other sentient creatures. Morillo supports her arguments with recent neuropsychological evidence concerning the role of reward centers in the brain and philosophical arguments for a naturalistic (...) theory of value and the good life. "Contingent Creatures" will interest philosophers, psychologists, and neurobiologists. (shrink)

Cognitive internalism is the view that moral judgments are both cognitive and motivating. Philosophers have found cognitive internalism to be attractive in part because it seems to offer support for the idea that moral reasons are categorical, that is, independent of agents’ desires. In this paper, I argue that it offers no such support.

I show that defenses of the Humean theory of motivation often rely on a mistaken assumption. They assume that desires are necessary conditions for being motivated to act because desires themselves have a special, essential, necessary feature, such as their world-to-mind direction of fit, that enables them to motivate. Call this the Desire-Necessity Claim. Beliefs cannot have this feature, so they cannot motivate. Or so the story goes. I show that: when pressed, a proponent of HTM encounters a (...) series of prima facie counterexamples to this Claim; and the set of claims that seem to naturally complement the Desire-Necessity Claim as well as provide successful responses to these counterexamples turn out to deny the truth of this same claim. As a result, the Humean implicitly grants that it is at least equally plausible, if not more plausible, to claim that desires are not able to motivate in virtue of what they necessarily possess. Instead, desires contingently possess features that enable them to motivate. (shrink)

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

In recent discussions of the Humean Theory of Motivation (HTM), several authors – not to mention other philosophers around the proverbial water cooler – have appealed to the simplicity of the theory to defend it. But the argument from simplicity has rarely been explicated or received much critical attention – until now. I begin by reconstructing the argument and then argue that it suffers from a number of problems. Most importantly, first, I argue that HTM is unlikely (...) to be simpler than even close competing theories, and second, it is unlikely that a plausible version of the theory will be very simple. Moreover, I argue that a convincing case for HTM is likely to have to show that it is more virtuous than defenders have done so far. (shrink)

The aim of this article is to offer a novel reconstruction of Sartre's theory of motivation. I argue for four related claims: (a) Sartre's theory of motivation revolves around the Schelerian‐inspired notion of affectivity and the peculiar way affectivity provides us access to evaluative properties of the objects in our environment; (b) according to Sartre, the structure of intentional action, and in particular the act of choice and commitment to projects, is inextricably linked with “affectivity”; (c) (...) the inextricable link between intentional action and affectivity is to be analyzed in terms of the fundamental structure of consciousness as being self‐present, thus making the agent nonpositionally aware of her choices and commitments; (d) an agent is motivated to act when her affective disclosure of value is in part constituted by the awareness of her commitments to relevant projects.

To the extent, then, that we set our face against admitting the truth of Humeanism in the theory of motivation, to that extent we are probably going to feel that there is no such thing as the theory of motivation, so conceived, at all. And that will be the position that this paper is trying to defend, though not only for this reason. It might seem miraculous that so much can be extracted from the little distinction (...) with which we started, between the reasons why an action was right and the agent's reasons for doing it. It is not so much the distinction itself which is the culprit, however, as the account of it that sees motivating reasons as complexes of beliefs and desires, i.e. as complexes of psychological states of whatever sort, and sees justifying reasons as truths. It is this account, which puts into form the attempt to combine value realism with Humean philosophical psychology, that leads to the results I have outlined above. (shrink)

I consider an underappreciated problem for proponents of the Humean theory of motivation. Namely, it is unclear whether is it to be understood as a largely psychological or largely metaphysical theory. I show that the psychological interpretation of HTM will need to be modified in order to be a tenable view and, as it will turn out, the modifications required render it virtually philosophically empty. I then argue that the largely metaphysical interpretation is the only a plausible (...) interpretation of HTM's central claim that desires are necessary conditions for motivation. This interpretation also fits better with the important roles that HTM plays in both moral psychological and metaethical debates. (shrink)

Abraham Maslow’s needs theory is one of the most influential motivation theories in management and organizational behavior. What are its anthropological and ethical presuppositions? Are they consistent with sound business philosophy and ethics? This paper analyzes and assesses the anthropological and ethical underpinnings of Maslow’s needs theory from a personalistic framework, and concludes that they are flawed. Built on materialistic naturalism, the theory’s “humanistic” claims are subverted by its reductionist, individualistic approach to the human being, which (...) ends up in a needs-based ethics that understands goodness, virtue, and rights in instinctual, subjectivistic, and relativistic terms. Its moral imperative, “Be yourself!,” is either the materialistic fiat of genetic drives or the voluntaristic command of unbridled will. Significant implications for business educators, managers, and organizations are discussed, along with recommendations. Managerial theories and approaches that reduce personality to individuality are inconsistent with proper anthropological and ethical business principles. Adopting those individualistic theories may ultimately undermine organizational effectiveness, and the very essence of business as human activity and of management as human calling. Instead, personalistic anthropology and virtue ethics, rooted in Aristotelian–Thomistic thought, soundly account for properly human nature and the good life. Business educators and practitioners are encouraged to embrace this integral, truly humanistic framework for motivation, and management theory and practice. (shrink)

According to the Humean theory of motivation, a person can only be motivated to act by a desire together with a relevantly related belief. More specifically, a person can only be motivated to ϕ by a desire to ψ together with a belief that ϕ-ing is a means to or a way of ψ-ing. In recent writings, Michael Smith gives what has become a very influential argument in favour of the Humean claim that desire is a necessary part (...) of motivation, and a great deal has been written about Smith's defence of this Humean claim. However, no one has yet identified the fundamental weakness of his defence. The fundamental weakness is that there is no single conception of directions of fit that does all the work Smith needs it to do throughout the various stages of his defence. (shrink)

In this paper I will argue against the Humean theory of motivation, or “conativism” which claims that all actions are ultimately generated by desires. Conativism is supported by (1) a behavioral analysis of desire as a disposition to act in certain ways, and (2) the difference between belief and desire in terms of their different “direction of fi t” with the world. I will show that this behavioral account of desire cannot provide an adequate explanation of action. Mere (...) disposition to act (what I call “wanting”) does not explain why the agent acts; insofar as it explains the action desire is a feeling. I will then argue against the direction of fit argument by showing that beliefs about what we ought to do have both directions of fit—the belief has one direction of fit, and the content of the belief (the ought-clause) has the opposite direction of fit.

Jonathan Dancy; I *—The Presidential Address: Why there is really No Such Thing as the Theory of Motivation, Proceedings of the Aristotelian Society, Volume 95.

Imagine that Socrates gets a cavity treatment. The drilling is painful, but he also knows that it is best to get it done and so he stays. Callicles is not so smart. Once the dentist starts drilling, Callicles takes off. I argue that this scenario presents a puzzle that interpreters have missed, namely: why does Socrates have an aversion to pain? To us, this might not be puzzling at all. Socrates, however, believes that we have an aversion only to bad (...) things and that pain is not in fact bad. If Socrates knows that pain is not bad, why does he still feel aversive pain from drilling? I argue that the Protagoras and Hippias Major suggest that pain immediately appears to be bad to us. So even though pain is not in fact bad, it appears and feels that way, and thus even Socrates has an aversion to it. Pain is a felt evaluation. My interpretation contributes to the debates in the literature in two ways. First, it fills an explanatory gap. Interpreters have acknowledged that a Socratic theory of motivation has room for pain aversions as “itches,” but they leave unexplained why we have an aversion to pain, i.e., why those itches itch. Second, I offer an alternative account of Socratic motivation by proposing that pain aversions can motivate some of our actions. (shrink)

Morality constructs the relationship between the self and others, providing a sense of appropriateness that facilitates and coordinates social behaviors. We start from Moral Foundation Theory (MFT), and argue that multiple moral domains can shape the meaning of public service and engender Public Service Motivation (PSM). From the lens of cognitive science, we develop a causal map for PSM by understanding the social cognition process underlying PSM, focusing on five innate moralities as the potential antecedents of PSM: Care, (...) Fairness, Authority, Loyalty, and Sanctity. Extending moral domains beyond compassion and justice can provide a disaggregated view of PSM, which may help to identify institutional and cultural variation in the meaning of PSM. We discuss the theoretical implications of synthesizing MFT and PSM literatures, and provide directions for future research that could improve our understanding of PSM. (shrink)

Realists about practical reasons agree that judgments regarding reasons are beliefs. They disagree, however, over the question of how such beliefs motivate rational action. Some adopt a Humean conception of motivation, according to which beliefs about reasons must combine with independently existing desires in order to motivate rational action; others adopt an anti-Humean view, according to which beliefs can motivate rational action in their own right, either directly or by giving rise to a new desire that in turn motivates (...) the action. I argue that the realist who adopts a Humean model for explaining rational action will have a difficult time giving a plausible account of the role that desire plays in this explanation. I explore four interpretations of this role and argue that none allows a Humean theory to explain rational action as convincingly as an anti-Humean theory does. The first two models, in different ways, make acting on a reason impossible. The third allows this possibility, but only by positing a reason-sensitive desire that itself demands an explanation. The fourth avoids this explanatory challenge only by retreating to an empty form of the Humean view. In contrast, an anti-Humean theory can provide an intuitively plausible explanation of rational action. I conclude that the realist about reasons should adopt an anti-Humean theory to explain rational action. (shrink)
