Is there epistemologically irrational knowledge?

Vol 22, No 2 (2018) • Principia: an international journal of epistemology

Abstract:

I present an epistemological puzzle about perceptual knowledge and its relation to the evaluation of probabilities. It involves cases, concerning a given subject and a proposition in a determinate context, where apparently: has perceptual knowledge of P; the epistemic justification has for believing Not-is much greater than her epistemic justification for believing P. If those two theses were true, the following very plausible epistemological principle would fail: If knows P, then the epistemic justification has for believing Not-is not greater than her epistemic justification for believing P. I offer a solution to the puzzle, which is compatible with basic intuitions and theses of orthodox Bayesianism.
