Resumen de Where there are internal defeaters, there are �confirmers�
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�.
