Abstract

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
