How can an agent's desire or will give him reasons for acting? Not long ago, this might have seemed a silly question, since it was widely believed that all reasons for acting are based in the agent's desires. The interesting question, it seemed, was not how what an agent wants could give him reasons, but how anything else could. In recent years, however, this earlier orthodoxy has increasingly appeared wrongheaded as a growing number of philosophers have come to stress the action-guiding role of reasons in deliberation from the agent's point of view. What a deliberating agent has in view is rarely his own will or desires as such, even if taking something as a reason is intimately tied to desire. Someone who wants to escape a burning building does not evaluate her options by considering which is likeliest to realize what she wants or wills. She is focused, rather, on her desire's object: getting out alive. The fact that a successful route would realize something she wants is apt to strike her as beside the point or, at best, as a trivial bonus.

Can desires and actions be evaluated as responsive or unresponsive to reasons, in ways that extend beyond the instrumental implications of one's (other) desires? And does there exist any form of inference or reasoning that is practical in nature? Hume is generally supposed to have given an unambiguously negative reply to both of these questions. In particular, he is often taken to have held that no desire, passion, or action may ever be said to be opposed to reasons, except (perhaps) in so far as it is based on a false belief or confused piece of means-ends reasoning. And he is generally taken to have held that the existence of some sort of peculiarly practical form of inference or reasoning is fundamentally ..

Alan H. Goldman argues for the internalist or subjectivist view of practical reasons on the grounds that it is simpler, more unified, and more comprehensible ...

In 'The Moral Problem', Michael Smith defends a conception of normative reasons that is nonrelative. Given his understanding of normative reasons, nonrelativity commits him to the convergence hypothesis: that, as a result of the process or correction of beliefs and rational deliberation, 'all' agents would converge on having the same set of desires. I develop several reasons for being pessimistic about the truth of this hypothesis. As a result, if normative reasons exist, we have a reason to be skeptical of either Smith's understanding of what normative reasons are or of his insistence that they are nonrelative.

This paper defends strong internalism about reasons, the view that reasons must relate to pre-existing motivational states, from several kinds of counterexamples, supposed desire independent reasons, that have been proposed. A central distinction drawn is that between there being a reason and an agent's having a reason. For an agent to have an F reason, she must be F-minded. Reasons, as what motivate us, are states of affairs and not themselves desires or motivational states, but they must connect to existing motivational states. It has been claimed that rationality itself requires us to recognize certain reasons independent of our desires, that we acquire new desires by learning what is valuable, by acquiring desire-independent reasons to pursue certain values. It is claimed also that prudential and moral reasons are desire independent. By offering an account of rationality as coherence, by appealing to broader concerns as opposed to specific desires, and by appealing to the distinction noted above, the paper exposes weaknesses in recent arguments for desire independent reasons by Millgram, Smith, Korsgaard, and Searle. the reasons they propose can be interpreted as internal (not desire independent) or dismissed as nonexistent.

Hume said that the reasons that determine the rationality of one's actions are the desires one has when acting: one's actions are rational iff they advance these desires. Thomas Nagel says this entails calling rational, actions absurdly conflicting in aims over time. For one might have reason, in one's current desires, to begin trying to cause states one foresees having reason, in one's foreseen desires, to prevent. Instead, then, real reasons must be timeless, so that current and foreseen reasons cannot conflict. I say the desire theory does not have absurd consequences. A rational agent's desires would rationally evolve, never requiring actions conflicting in aims over time, except where it was instrumentally rational for her to change in her desires, whence such conflicts are rationally appropriate. Further, whatever sorts of things count as real reasons, since reasons can rationally require their own revision, they cannot be necessarily timeless.

One of the most important disputes in the foundations of ethics concerns the source of practical reasons. On the desire-based view, only one’s desires provide one with reasons to act. On the value-based view, reasons are instead provided by the objective evaluative facts, and never by our desires. Similarly, there are desire-based and non-desired-based theories about two other issues: pleasure and welfare. It has been argued, and is natural to think, that holding a desire-based theory about either pleasure or welfare commits one to recognizing that desires do provide reasons for action – i.e., commits one to abandoning the value-based theory of reasons. The purpose of this paper is to show that this is not so. All of the following can be true: pleasure and welfare provide reasons; pleasure and welfare are to be understood in terms of desire; desires never provide reasons, in the relevant way.

An influential view, defended by Thomas Scanlon and others, holds that desires are almost never reasons. I seek to resist this view and show that someone who desires something does thereby have a reason to satisfy her desire. To show this, I argue, first, that the desires of some others are reasons for us and, second, that our own desires are no less reason-giving than those of others. In concluding, I emphasize that accepting my view does not commit one to a desire-based account of reasons. Desires can be simply one kind of reasons alongside many others.

Many believe that the rational evaluation of actions depends on the rational evaluation of even basic desires. Hume, though, viewed desires as "original existences" which cannot be contrary to either truth or reason. Contemporary critics of Hume, including Norman, Brandt and Parfit, have sought a basis for the rational evaluation of desires that would deny some basic desires reason-giving force. I side with Hume against these modern critics. Hume's concept of rational evaluation is admittedly too narrow; even basic desires are, despite their nonrepresentational nature, subject to rational evaluation. But this evaluation is not relevant to their tendency to generate reasons for action, and does not undermine the spirit of the Humean view of rational action.

Jonathan Dancy’s Practical Reality makes a significant contribution to clarifying the relationship between desire and reasons for acting, both the normative reasons we seek in deliberation and the motivating reasons we cite in explanation. About the former, Dancy argues that, not only are normative reasons not all grounded in desires, but, more radically, the fact that one desires something is never itself a normative reason. And he argues that desires fail to figure in motivating reasons also, concluding that neither the fact nor the state of desire is ever a motivating reason for acting. I am in significant agreement with Dancy about these matters, but I want to register some reservations nonetheless. Dancy is certainly right to reject the DBR (desire-based reasons) thesis that all normative reasons are grounded in desires.1 Desires, he points out, call for reasons no less than do actions. But I think he insufficiently appreciates a way in which facts about the agent’s desires and related practical psychic states can provide normative reasons. Not that this gives away anything to Dancy’s Humean opponents. What gives an agent’s desires, values, and moral convictions normative weight, I shall suggest, is her dignity and integrity as an individual person.
