Epistemic Frankfurt Cases Revisited
by Christoph Kelp
In Kelp (2009a), it is argued that there are epistemic Frankfurt cases that serve to show that knowledge
does not require safety from error. In this paper, these Frankfurt cases are revisited. It is first argued
that a recent response to the earlier argument by Duncan Pritchard remains unsatisfactory. Then it
is shown that Frankfurt cases impact a much wider range of accounts. Specifically, it is argued in
some detail that, in conjunction with the infamous Fake Barn cases, they generate a problem for the
two most prominent virtue theoretic accounts of knowledge, due to Ernest Sosa and John Greco.
