Gettier Beliefs and Serious Beliefs

In a recent exchange in the pages of this journal, John Biro responds to Gabor Forrai’s argument against Biro’s argument that in most, if not all, Gettier cases the belief condition, contra popular opinion, isn’t satisfied. In this note, I’ll argue that Biro’s response to Forrai satisfactorily resolves the first of Forrai’s two central objections to Biro’s argument that the belief condition isn’t satisfied in most, if not all, Gettier cases. But Biro’s response leaves mostly unaddressed the most plausible way of construing Forrai’s second objection. I’ll take up the mantle of successfully defending Biro’s argument from this more plausible construal of Forrai’s second objection. However, even though I’ll argue that Biro’s argument is in good shape with respect to Forrai’s objections, I’ll show that the definition of serious belief that Biro offers us is mistaken.
