Abstract

Impropriety due to lack of a particular epistemic feature suffices for epistemic impropriety; and (2) Having justification to believe P suffices for having warrant to assert P. I present and defend arguments against both claims. These arguments undermine (among other things) (a) the main counterexamples to the view that knowledge suffices for warrant to assert; (b) a main argument that justified belief suffices for knowledge; and (c) a promising defense of the Credit Requirement on knowledge.
