As everyone is locked up, Clayton Littlejohn has been helpfully recording and gather talks on some recent work in philosophy. This talk is an informal presentation of a paper written with Julien Dutant on epistemic rationality and defeat. It presents a new unified theory of defeat according to which the toxicity of rationality defeaters has to do with the way in which they serve as indicators that we cannot know certain things. The paper engages with recent work on epistemic paradoxes, epistemic rationality, and recent work on defeat.
