Hume on Characters, Virtues, and "Durable Principles of the Mind"

Abstract: Hume is widely understood to believe that all virtues and vices are "durable principles of the mind," and that durable principles of the mind are character traits. Several scholars therefore read him as a virtue ethicist. I argue that we should reject all such interpretations. I argue that Hume allows that some virtues and vices are simply single perceptions, such as a motivationally strong desire to help a stranger or to murder someone. Therefore, I argue, we should not read him as a virtue ethicist. Hume is, however, a reductionist about character, who understands a character trait as simply a long-lasting but interrupted succession of perceptions. On my interpretation, a durable principle of the mind is an uninterrupted, relatively short-lived succession of different perceptions within an actor's mind, of a kind that mainly interests Hume because he thinks it enables observers to associate a person's action with her mind.
