The truth of a philosophy is not to be tested by what we feel about it in moods of practical common-sense; for in these moods we have, for some superficial reason, suppressed more than half of the attributes of our soul. The truth of a philosophy can only be tested in those moments when the soul, driven to the wall, gathers itself together for one supreme effort. But there is, even in less stark and drastic hours, an available test of a sound and organic philosophy which must not be forgotten. I refer to its capacity for being vividly and emphatically summed up and embodied in some concrete image or symbol. If a philosophy is so rationalistic that it refuses to lend itself to a definite and concrete expression we are justified in being more than suspicious of it. And we are suspicious of it not because its lack of simplicity makes it intricate and elaborate, for "reality" is intricate and elaborate; but because its inability to find expression for its intricacy in any concrete symbol is a proof that it is too simple. For the remote conclusions of a purely logical and rationalistic philosophy are made to appear much less simple than they really are by reason of their use of remote technical terms. What the soul demands from philosophy is not simplicity but complexity, for the soul itself is the most complex thing we know. The thin, rigid, artificial outlines of purely rationalistic systems can never be expressed in ritual or symbol or drama, not because they are too intricate, but because they are not intricate enough. A genuine symbol, or ritualistic image, is a concrete living organic thing carrying all manner of magical and subtle associations. It is an expression of reality which comes much nearer to reality than any rationalistic system can possibly do. A genuine symbolic or ritualistic image is a concrete expression of the complexity of life. It has the creative and destructive power of life. It has the formidable mysteriousness of life, and with all this it has the clear-cut directness of life's terrible and exquisite tangibility. When suddenly confronted, then, in the mid-stream of life, by the necessity of expressing the starting-point, which is also the conclusion, of the philosophy of the complex vision, what synthetic image or symbol or ritualistic word are we to use in order to sum up its concrete reality? The revelation of life, offered to us by the complex vision, is, as we have seen, no very simple or logical affair. We axe left with the spectacle of innumerable "souls," human, sub-human and super-human, held together by some indefinable "medium" which enables them to communicate with one another. Each one of these "souls" at once creates and discovers its own individual "universe" and then by an act of faith assumes that the various "universes" created and discovered by all other souls are identical with its own.
