Abstract
Hume’s three principles of association, we are led to believe from the way Hume introduces them, are supposed to account for the formation of complex ideas out of simple ones. But the account he gives, I show, is pretty poor. But Hume, in fact, has an additional issue in mind: accounting for thoughts we have with ideas we already possess, e.g.: the way one idea brings to one’s conscious mind an idea previously formed and now lying dormant, so to speak. The answer Hume gives to this question, I argue, is quite passable.
