HUME AND THE SECOND-QUALITY ANALOGY

Abstract

In this paper I consider Hume's position on the analogy between moral qualities and secondary qualities. Although some have suggested that Hume's use of the analogy is important to his moral philosophy, others have disputed its significance to Hume. My position in this paper is that Hume believes there are indeed similarities between moral and secondary qualities that illuminate the nature of virtue. This paper is divided into two parts. In the first, I consider Hume's point(s) in raising the analogy by arguing for four similarities between moral qualities and secondary qualities that he likely had in mind; and in the second, I respond to various objections alleging that Hume did not, and indeed, could not, rely on the analogy in any substantial way.
