Knowledge Is not Factually Grounded Belief

Gualtiero Piccinini has recently proposed an interesting new solution to the Gettier Problem: Knowledge is factually grounded belief. But there is a problem with this purported solution: It is both too strong and too weak. In this paper, I provide two counterexamples to substantiate the claim that it is both too strong and too weak. Thus, the view that knowledge is factually grounded belief is inadequate as an account of knowledge.
