The theory that practical reasoning is wholly instrumental says that the only practical function of reason is to tell agents the means to their ends, while their ends are fixed by something other than reason itself. In this essay I argue that Hume has an instrumentalist theory of practical reasoning. This thesis may sound as unexciting as the contention that Kant is a rationalist about morality. For who would have thought otherwise? After all, isn't the ‘instrumentalist’ line in contemporary discussions of this topic descended directly from Hume himself? Contrast the following recent comment from Robert Audi's book on practical reasoning, holding the standard line, with the comment from Christine Korsgaard following it:Hume's conception of practical reasoning, so far as we can formulate it, can be located within … the foundationalist account of motivation in which reason plays the instrumentalist role … by virtue of arousing and directing our desires.

On Hume's account, when we lack virtues that would typically prompt moral action, we can instead be motivated by the "sense of duty." Surprisingly, Hume seems to maintain that, in such cases, we are motivated by a desire to avoid the unpleasantness of "self-hatred" evoked in us when we realize we lack certain traits others possess. This account has led commentators to argue that Hume is not a moral internalist, since motivation by duty is motivation by a self-interested desire. This paper concludes that Hume is indeed a moral internalist and that the motive of duty can be understood as a form of motivation by moral disapprobation in a way supported by Hume's general motivational psychology

Hume’s distinction between the calm and violent passions is one whose boundaries are not entirely clear. However, it is crucial to understanding his motivational theory and to identifying an unusual virtue he calls “strength of mind,” the motivational prevalence of the calm passions over the violent. In this paper, I investigate the boundaries of the calm passions and consider the constitution of strength of mind and why Hume regards it as an admirable trait. These are provocative issues for two reasons. First, it seems as though one might exhibit the prevalence of calm over violent passions, even if the prevailing calm passions are vicious traits of character. Second, the natural virtues for Hume are non-moral motives that garner approval for the effects they tend to produce. But strength of mind is unique in that it is not defined in terms of a particular motive, but in terms of the causal force (strength) of any number of motives in competition with others.

Most naturalists think that the belief/desire model from Hume is the best framework for making sense of motivation. As Smith has argued, given that the cognitive state (belief) and the conative state (desire) are separate on this model, if a moral judgment is cognitive, it could not also be motivating by itself. So, it looks as though Hume and Humeans cannot hold that moral judgments are states of belief (moral cognitivism) and internally motivating (moral internalism). My chief claim is that the details of Hume’s naturalistic philosophy of mind actually allow for a conjunction of these allegedly incompatible views. This thesis is significant, since readers typically have thought that Hume’s view that motivation is not produced by representations, coupled with his view that moral judgments motivate on their own, imply that moral judgments could never take the form of beliefs about, or representations of, the moral (virtue and vice).

in a recent article entitled “Hume on the Passions,” Stephen Buckle opens with the claim that Hume’s theory of the passions has largely been neglected. “Apart from a couple of famous sections in the Treatise concerning the sources of action,” he writes, “the subject matter has rarely excited interest.”1 His analysis of why the subject of the passions in Hume has been uninspiring points to the fact that readers have largely misunderstood the point of Hume’s theory. They usually regard the account as yet another mechanistic analysis of the passions in the vein of seventeenth-century science, alongside the offerings of Malebranche, Hobbes, and Spinoza. Buckle is right to point out that there is a..
