Abstract

The cases of Norman the Clairvoyant and Mr. Truetemp form classic counterexamples to the process reliabilist's claim that reliability is sufficient for prima facie justification. I discuss several ways in which contemporary reliabilists have tried to deal with these counterexamples, and argue that they are all unsuccessful. Instead, I propose that the most promising route lies with an appeal to a specific kind of higher-order defeat that is best cashed out in terms of properly functioning monitoring mechanisms
