words, can expel from your belief. The opinion opposed to mysticism in philosophy is sometimes spoken of as rationalism. Rationalism insists that all our beliefs ought ultimately to find for themselves articulate grounds. Such grounds, for rationalism, must consist of four things: (1) definitely statable abstract principles; (2) definite facts of sensation; (3) definite hypotheses based on such facts; and (4) definite inferences logically drawn. Vague impressions of something indefinable have no place in the rationalistic system, which on its positive side is surely a splendid intellectual tendency, for not only are all our philosophies fruits of it, but physical science (amongst other good things) is its result.
Nevertheless, if we look on man's whole mental life as it exists, on the life of men that lies in them apart from their learning and science, and that they inwardly and privately follow, we have to confess that the part of it of which rationalism can give an account is relatively superficial. It is the part that has the prestige undoubtedly, for it has the loquacity, it can challenge you for proofs, and chop logic, and put you down with words. But it will fail to convince or convert you all the same, if your dumb intuitions are opposed to its conclusions. If you have intuitions at all, they come from a deeper level of your nature than the loquacious level which rationalism inhabits. Your whole subconscious life, your impulses, your faiths, your needs, your divinations, have prepared the premises, of which your consciousness now feels the weight of the result; and something in you absolutely knows that that result must be truer than any logic-chopping rationalistic talk, however clever, that may contradict it. This inferiority of the rationalistic level in founding belief is just as manifest when rationalism argues for religion as when it argues against it. That
