Humeans claim that all motivation is by desire. Anti-Humeans maintain that some beliefs can motivate all by themselves. This dispute, I argue, hinges on the question whether belief can rationalize motivation. Moreover, I argue belief can rationalize motivation since rationality requires that one be motivated to φ if one believes one has most reason to φ, and it is possible to be motivated to φ because one believes one has most reason to φ and one exercises one's capacity for rational (...) agency.

The causal theory of reasons holds that acting for a reason entails that the agents action was caused by his or her beliefs and desires. While Donald Davidson (1963) and others effectively silenced the first objections to the theory, a new round has emerged. The most important recent attack is presented by Jonathan Dancy in Practical Reality (2000) and subsequent work. This paper will defend the causal theory against Dancy and others, including Schueler (1995), Stoutland (1999, 2001), and Ginet (2002).Dancy (...) observes that our reasons are neither psychological states nor causes, and that our reasons can be both motivating and normative. I argue that these observations are fully compatible with the causal theory. According to the reductive version I develop for both cognitive and optative reasons, what it is for an action to be done for a reason is for certain beliefs and desires to cause the action in a particular way. Our reasons for action are the objects of some of those beliefs and desires. The causal process has two stages. This theory explains not only Dancys observations, but also many other facts about reasons that alternative theories leave unexplained. I argue against Schueler and others that the non-appetitive desires entailed by acting for reasons are no less distinct and independent causal factors than the beliefs entailed. I go on to rebut arguments that the relation between psychological states and actions cannot be causal because it is non-empirical, rational, normative, or non-deterministic, and that explanations in terms of psychological causes are incompatible with explanations in terms of reasons.

Rationalists including Nagel and Korsgaard argue that motivation to the means to our desired ends cannot be explained by appeal to the desire for the end. They claim that a satisfactory explanation of this motivational connection must appeal to a faculty of practical reason motivated in response to desire-independent norms of reason. This paper builds on ideas in the work of Hume and Donald Davidson to demonstrate how the desire for the end is sufficient for explaining motivation to the means. (...) Desiring is analyzed as having motivation towards making the end so, which is analyzed as engaging in mental activity aimed at facilitating that end. I conclude that it is constitutive of an agent’s desiring an end that he is motivated towards what he believes to be means. (shrink)
