Keith DeRose presents, develops, and defends original solutions to two of the stickiest problems in epistemology: skeptical hypotheses and the lottery problem. He deploys a powerful version of contextualism, the view that the epistemic standards for the attribution of knowledge vary with context.

It has been frequently suggested that epistemic contextualists violate the knowledge norm of assertion; by its own lights contextualism cannot be known and hence not be knowingly stated. I have defended contextualists against this objection by showing that it rests on a misunderstanding of their commitments. In M. Montminy's and W. Skolits' recent contribution to this journal, their criticism of my solution forms the background against which the authors develop their own. The present reply ventures to demonstrate that their objections (...) are ineffective, since they rest on a confusion of two different ways in which contextualism is unknowable. The precise nature of the original problem will be clarified and my solution briefly restated. (shrink)
