Abstract

Hume believes that distinctively moral sentiments can only be felt from a disinterested perspective. While much scholarly attention has been paid to the question of how Hume believes we “correct” our moral sentiments to form a coherent moral language, less has been paid to the question of why we first adopt this disinterested vantage point. Answering this question involves determining what, for Hume, enables our disinterested point of view to influence us despite the fact that the sentiments produced by our parochial vantage points are originally stronger. I term this the “influence question.” I contend that Hume has two answers to this question: one in the Treatise and one in the second Enquiry. While the former is based upon our ability to share sentiments with others via sympathy, the latter holds that our disinterested vantage point enables us to found the “party of humankind” upon the universal principle of humanity. I argue that Hume saw this latter answer as rectifying a certain deficiency in his Treatise explanation and that his later answer supports Hume’s aim of demonstrating that morality is a fundamentally social phenomenon.
