What are the comparative roles of reason and the passions in explaining human motivation and behaviour? Accounts of practical reason divide on this central question, with proponents of different views falling into rationalist and Humean camps. By 'rationalist' accounts of practical reason, I mean accounts which make the characteristically Kantian claim that pure reason can be practical in its issue. To reject this view is to take the Humean position that reasoning or ratiocination is not by itself capable of giving rise to a motivation to act. My own view is that the rationalist position can, in the end, be sustained against the challenge of these Humean arguments. To see why, however, it will be necessary to get clear about what is really at stake in the debate about practical reason. A further aim of my discussion will accordingly be to sharpen our understanding of the issue that divides Humeans and rationalists.

Abstract Motivation in an automaton, whether it be artificial or animate, is simply that aspect of the total state that determines the behaviour. In an autonomous agent, which has a degree of self?control, the motivational state includes a cognitive evaluation of the likely consequences of possible future behaviour. Such evaluation implies optimization with respect to some motivational criterion.

The category of emotions covers a disputed territory, but clear examples include fear, anger, joy, pride, sadness, disgust, shame, contempt and the like. Such states are commonly thought of as antithetical to reason, disorienting and distorting practical thought. However, there is also a sense in which emotions are factors in practical reasoning, understood broadly as reasoning that issues in action. At the very least emotions can function as "enabling" causes of rational decision-making (despite the many cases in which they are disabling) insofar as they direct attention toward certain objects of thought and away from others. They serve to heighten memory and to limit the set of salient practical options to a manageable set, suitable for "quick-and-dirty" decision-making.

In this paper, I shall discuss the relation between practical reason and emotions in Kant. First, I begin by explaining why knowledge of emotions is important for the transcendental project in the moral domain, understood as the claim that reason can determine our actions, in spite of our inclinations. Second, I explain the definition of affects and passions in Kant's philosophy and relate the two to feelings and the faculty of desire. I then question the possibility of controlling emotions, showing that it is, if not an altogether impossible task, at least a difficult one. I show that while affects present a momentary loss of control, they can still coexist with practical reason. Passions, however, may ground principles for actions, and represent a serious danger for rational mastery over inclinations.

In her influential and challenging paper “Skepticism about Practical Reason” Christine Korsgaard sets out to refute an important strand of Humean scepticism as it concerns a Kantian understanding of practical reason.1 Korsgaard distinguishes two components of scepticism about practical reason. The first, which she refers to as content scepticism, argues that reason cannot of itself provide any “substantive guidance to choice and action” (SPR, 311). In its classical formulation, as stated by Hume, it is argued that reason cannot determine our ends. Our ends are determined by our desires and reason is limited to the role of identifying the relevant means to these ends. The second component, which Korsgaard calls motivational scepticism, suggests doubt about the scope of reason as a motive. The claim here, as Korsgaard interprets Hume’s view on this matter, is that “all reasoning that has motivational influence must start from a passion, that being the only possible source of motivation” (SPR, 314).2 Korsgaard’s fundamental objective in “Skepticism about Practical Reason” is to show that motivational scepticism must always be based on content scepticism. In other words, according to Korsgaard, motivational scepticism has no independent force. In this paper I argue that Korsgaard’s attempt to discredit motivational scepticism is unsuccessful.

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.

In trying to explain the possibility of akrasia (weakness of will), it seems plausible to deny that there is a conceptual connection between motivation (what one wants) and evaluation (what one judges to be good); akrasia occurs when the agent is (most) motivated to do something that she does not judge to be good (all things considered). However, it is hard to see how such accounts could respect our intuition that the akratic agent acts freely, or that there is a difference between akrasia and compulsion. It is also hard to see how such accounts could be extended to the realm of theoretical reason, but this is generally not taken to be a problem, because it is generally assumed that there is no similar phenomenon in the realm of theoretical reason. This paper argues that there is such a thing as theoretical akrasia, and that we can find a characterization of this phenomenon in Descartes's Meditations. Drawing on certain passages in the Meditations, we can construct an account of theoretical akrasia; this account can then be adapted to resolve the original problem of akrasia in the realm of practical reason. The account asserts that there is a conceptual connection between motivation and evaluation in free action; it also enables us to show how the akratic agent is still acting freely when he does something that he does not judge to be the best all things considered.

'We desire all and only those things we conceive to be good; we avoid what we conceive to be bad.' This slogan was once the standard view of the relationship between desire or motivation and rational evaluation. Many critics have rejected this scholastic formula as either trivial or wrong. It appears to be trivial if we just define the good as 'what we want', and wrong if we consider apparent conflicts between what we seem to want and what we seem to think is good. In Appearances of the Good, Sergio Tenenbaum argues that the old slogan is both significant and right, even in cases of apparent conflict between our desires and our evaluative judgments. Maintaining that the good is the formal end of practical inquiry in much the same way as truth is the formal end of theoretical inquiry, he provides a fully unified account of motivation and evaluation.

How can we motivate ourselves to do what we think we ought? How can we deliberate about personal values and priorities? Bennett Helm argues that standard philosophical answers to these questions presuppose a sharp distinction between cognition and conation that undermines an adequate understanding of values and their connection to motivation and deliberation. Rejecting this distinction, Helm argues that emotions are fundamental to any account of value and motivation, and he develops a detailed alternative theory both of emotions, desires, and evaluative judgments and of their rational interconnections. The result is an innovative theory of practical rationality and of how we can control not only what we do but also what we value and who we are as persons.
