 Such pseudo-dialecticians take reason to be the final arbiter of all claims, including claims about matters of faith. More exactly, Abelard charges them with holding that (a) everything can be explained by human reason; (b) we should only accept what reason persuades us of; (c) appeals to authority have no rational persuasive force. Real dialecticians, he maintains, reject (a)–(c), recognizing that human reason has limits, and that some important truths may lie outside those limits but not beyond belief; which claims about matters of faith we should accept depends on both the epistemic reliability of their sources (the authorities) and their consonance with reason to the extent they can be investigated.
