It is easy to see, though it scarcely needs to be pointed out, since it is involved in the fact that Reason is set aside, that faith is not a form of knowledge; for all knowledge is either a knowledge of the eternal, excluding the temporal and historical as indifferent, or it is pure historical knowledge. No knowledge can have for its object the absurdity that the eternal is the historical.
