Abstract

In recent articles in this journal Benoit Gaultier and John Biro have argued that the original Gettier cases and the ones closely modelled on them fail, and the reason for the failure is that the subject in these cases does not actually have the belief that would serve as a counterexample to the justified-true-belief analysis of knowledge. They claim that if our evidence pertains to a particular individual (as in the first case) or to the truth of one of the disjuncts (as in the second case), we do not genuinely believe the existential generalization or the disjunction which logically follows. I will challenge their arguments and suggest that our unwillingness to assert the existential generalization or the disjunction under these conditions does not stem from lack of belief but from pragmatic principles.
