One of key myths of humanism is the idea of neutrality. It is held that the mind of man can be neutral with regard to facts and ideas, and that the scientific method is the way of neutrality. Man can, we are told, calmly and objectively approach and analyze facts and arrive at the truth.
Such a view presupposes neutrality in the knower and the known. With respect to the knower, man, it assumes that man is not a fallen creature, at war with his Maker. Rather, man is held to be a being capable of approaching factuality objectively and impartially, so that the basic judgments about the nature of things depend upon the mind of man.
