Timothy Williamson (2000) makes a strong prima facie case for the identification of a subject's total evidence with the subject's total knowledge (E = K). However, as Brian Weatherson (Ms) has observed, there are intuitively problematic consequences of E = K. In this article, I'll offer a contextualist implementation of E = K that provides the resources to respond to Weatherson's argument; the result will be a novel approach to knowledge and evidence that is suggestive of an unexplored contextualist approach to basic knowledge

Having fascinated some of the greatest philosophers from the earliest times, dreaming figures importantly in the history of philosophy, as in Plato’s Theaetetus, Augustine’s Confessions, and, perhaps most famously, Descartes’s Mediations. By far the greatest philosophical focus on dreaming has been epistemic: Socrates suggests to Theaetetus that since he cannot tell whether he is dreaming, he cannot trust his senses to know contingent facts about the world around him. And a similar worry drives Descartes’s radical doubt in the First Meditation. We might think that dream skepticism is, among the radical Cartesian skeptical scenarios, a particularly worrying one, since dreams, unlike evil demons, are a commonplace of everyday life.

According to some critics, traditional armchair philosophical methodology relies in an illicit way on intuitions. But the particular structure of the critique is not often carefully articulated—a significant omission, since some of the critics’ arguments for skepticism about philosophy threaten to generalize to skepticism in general. More recently, some experimentalist critics have attempted to articulate a critique that is especially tailored to affect traditional methods, without generalizing too widely. Such critiques are more reasonable, and more worthy of serious consideration, than are blunter critiques that generalize far too widely. I argue that a careful (empirical!) examination of extant philosophical practices shows that traditional philosophical methods can meet these more reasonable challenges.
