Accidental truth and accidental justification

The presence of accidentality in a subject's holding a belief is generally thought to be incompatible with that belief's being an instance of knowledge. Epistemologists have tended to focus on the accidentality of the truth of a belief. I argue (a) that it is also possible mat there be accidentality in the justification of a belief, and (b) that the consequences of this type of accidentality are potentially much more harmful than accidentality only in the truth of a belief.
