 However, Hume argues that there is a common mechanism in human nature that gives rise to, and often even provides justification for, such judgments.He takes this aesthetic sense to be quite similar to the moral sense for which he argues in his Book 3 of "A Treatise of Human Nature" (1739–1740) and in "An Enquiry Concerning the Principles of Morals" (1751).Furthermore, he argues that this still leaves room for the ability to refine one's aesthetic palate.
