There are two kinds of knowledge: knowledge of things and knowledge of truth. So far as “things” are concerned, they display no attribute which cannot be elucidated by direct argument. But where truths are concerned, it is only indirect argument which can throw any light upon them. Indeed, in the case of scientific truths, the validity of indirect, or inferential argument is a matter of general acceptance. Since religious truths are proved by the logic of similar inferential argument, it may legitimately be argued that they fall into the same intellectual bracket as scientific truths.
