Abstract
It is widely assumed that the notion of doxastic justification should be explained in terms of the more fundamental notion of propositional justification, a notion which itself explains evidential support relations as a priori knowable. It is argued here, following Goldman, that this is a mistake. Doxastic justification is the more fundamental notion, and once one sees this, one must recognize that evidential support relations have an ineliminable psychological dimension which undermines the claim that they are knowable a priori.
