By Rationalism is meant the system or theory which assigns undue authority to reason in matters of religion. By reason is not to be understood the Logos as revealed in man, as held by some of the Fathers, and by Cousin and other modern philosophers, nor the intuitional faculty as distinguished from the understanding or the discursive faculty. The word is taken in its ordinary sense for the cognitive faculty, that which perceives, compares, judges, and infers.
