Abstract
This paper explores two aspects of Hume's skeptical crisis in the conclusion to _Treatise<D> Book I: his involved personal experience of the crisis, and his detached naturalistic reflection on it. I discuss several distinct states of mind reported in the text, ranging from extreme skepticism that rejects all belief, to natural dogmatism that rejects all reflection, to mitigated skepticism that tries to reconcile reflection and belief. I argue against interpretations according to which Hume's skepticism supports his naturalism, and I suggest that Hume's extreme skepticism ultimately depends on a predisposition to think of the crucial elements of human cognition as "trivial", as epistemically disabling rather than enabling
