Abstract

Robert Almeder has argued1 that three “fourth conditions” for nondefectiveness of knowledge justification claims, proposed in the recent literature,2 are essentially similar, require modification in order to eliminate the possibility of an unknowable defeater, and, so modified, render attainment of non-basic factual knowledge impossible. Although I believe there are objections to be raised against his exposition and reduction of the three proposed fourth conditions, I wish only to raise some doubts about the supposed necessity of the modifications and then to argue against his claim that, so modified, the result is too stringent.
