Abstract

There is widespread consensus that there are undercutting and rebutting defeaters that diminish or destroy the warrant of a belief B. I argue that there are counterparts of defeaters: the counterparts of undercutting defeaters are “requirement fulfillment beliefs”, the counterparts of rebutting defeaters are “consistency beliefs”. These beliefs confirm the warrant of B, I therefore call them “confirmers”.
