Upping the Ex Ante Problem for Reliabilism

Process reliabilism is a theory about ex post justification, the justification of a doxastic attitude one has, such as belief. It says roughly that a justified belief is a belief formed by a reliable process. It is not a theory about ex ante justification, one's justification for having a particular attitude toward a proposition, an attitude one might lack. But many reliabilists supplement their theory such that it explains ex ante justification in terms of reliable processes. In this paper, I argue that the main way reliabilists supplement their theory fails. In the absence of an alternative, reliabilism does not account for ex ante justification.
