 Critics of conciliationism offer a number of reasons for rejecting it as a systematic epistemic requirement. One line of criticism runs as follows. Conciliationism may well be self-refuting. Since the truth of conciliationism is itself a matter of controversy, a proponent of conciliationism should become much less convinced of its truth when he learns about this controversy. One may worry that there is something wrong with a principle that tells you not to believe in its own truth. (For further discussion, see Christensen 2013.)
