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.

In this paper, I discuss the implications of Hutcheson’s and Hume’s sentimentalist theories for the question of whether and how we can offer reasons to be moral. Hutcheson and Hume agree that reason does not give us ultimate ends. Because of this, on Hutcheson’s line, the possession of affections and of a moral sense makes practical reasons possible. On Hume’s view, that reason does not give us ultimate ends means that reason does not motivate on its own, and this makes practical reasons, strictly speaking, impossible. For Hutcheson, those who are good people (benevolent people) have reasons to continue in that way. While he has nothing to say to those who are thoroughly self-interested, he thinks there are no such persons. Hume’s theory implies that one can have a motive to behave morally when one’s character does not so incline, since he believes that morality is at least sometimes in the interest of the agent. One interesting source of their differences is that Hume subscribes to an internal connection between justification and motivation, while Hutcheson argues that motivating reasons and justifying reasons are logically distinct.
