What kind of Classical Foundationalism has Plantinga refuted?

Abstract

Alvin Plantinga declared in 1983 that Classical Foundationalism had collapsed. He was convinced that he had found an utterly damaging argument against CF: CF is self-referentially incoherent. Already Alston (1985) and Quinn (1985 and 1993) and recently DePoe (2007) have denied that Plantinga’s argument is successful. There are three objections against his argument: i) He has to show that there is no argument for CF; ii) there may be an inductive argument for CF; iii) there are other good arguments for CF, presented e.g. by Richard Fumerton. In this paper I will argue that i) is wrong and that Quinn’s inductive argument (ii) fails. Plantinga has shown that the “old” type of CF is self-refuting. Plantinga’s argument is not successful if aimed against a contemporary Fumerton-style CF because this type of CF differs in at least one relevant aspect from the kind of CF Plantinga was struggling with.
