Humeans about practical reasoning have tried to explain how some of our desires are reason‐giving and some are not. On one account, we act from reasons only when we act on desires that cohere in a consistent set. On another account, we act on reasons only when we act on desires that do not undermine our values. Both accounts are problematic. First, the notion of a consistent set of desires is vague and introduces a criterion not necessarily rooted in the agent's own motivations. Second, valuing is a matter of degree: we cannot divide desires into those that reflect values and those that don't. I maintain instead that all desires are reason‐giving, but we have best reason to do what we most care about, and the rationality of desires derives from the normative perspective we take on our desires in attempting to determine their relative importance to us

That Hume 's theory can be interpreted in two widely divergent ways-as a version of sentimentalism and as an ideal observer theory-is symptomatic of a puzzle ensconced in Hume 's theory. How can the ground of morality be internal and motivating when an inference to the feelings of a spectator in "the general point of view" is typically necessary to get to genuine moral distinctions? This paper considers and rejects the suggestion that in moral education, for Hume, the inculcation of morality internalizes the sentiments of the ideal observer. It ultimately offers a different resolution of the conflicting strains

Hume argues against the seventeenth-century rationalists that reason is impotent to motivate action and to originate morality. Hume's arguments have standardly been considered the foundation for the Humean theory of motivation in contemporary philosophy. The Humean theory alleges that beliefs require independent desires to motivate action. Recently, however, new commentaries allege that Hume's argument concerning the inertness of reason has no bearing on whether beliefs can motivate. These commentaries maintain that for Hume, beliefs about future pleasurable and painful objects on their own can produce the desires that move us to action. First, I show that this reading puts Hume at odds with Humeans, since the latter are committed, not only to the view that beliefs and desires are both necessary to action, but also to the view that beliefs do not produce desires. Second, I review textual, philosophical and historical grounds for my interpretation of Hume's argument for the inertness of reason. I argue that the new line on Hume, while consistent with a certain reading of the Treatise, is not supported by the Dissertation on the Passions and the second Enquiry, where Hume argues that all motivation has an origin in “taste”, which I take to be different from belief. Thus, Hume's arguments do support the contemporary Humean theory of motivation.
