But not only can reason thus set itself up in isolated usurpation against such other activities as imagination, intuition, will or taste; it can also divide itself against itself and emerge in completely contradictory functions. In the form of mathematical logic, for instance, it can dispose most drastically of that living organic world which in the form of experimental science it assumes to be the only truth. Again it may happen that reason will arbitrarily ally itself with one or the other of the other attributes and on the strength of such an alliance seek to obliterate all the rest. Thus while it is impossible to avoid the admission that of all these basic attributes reason is the most important, because without it all the rest would be inarticulate and dumb, it remains true that to hold reason in balanced relation to all the rest and to hold its own contradictory tendencies in balanced relation to one another is an undertaking of such extraordinary difficulty that if it were not for the complex vision's possession of that co-ordinating power which I have named its apex-thought, one might well pardon the mood of those persons who use reason to drug reason and who steer their boat into some unruffled backwater of dogma or mysticism. The necessity of such an infinitely delicate poise or balance or rhythm in these high matters, the necessity of keeping all these conflicting attributes at this exquisite point of suspense between abysses of contradiction, is a necessity which compels us to recognize that philosophy is nothing more or less than the supreme art, and the most difficult of all arts. Certainly, it seems as though thought has to become in a profound sense rhythmical, has to take to itself the nature of music, before it can become the truth. For the truth does not seem to be a mere picture of the system of things, reflected in the mirror of the mind. The truth seems to be the very system of things itself, become conscious and volitional, changing, growing, living, destroying, creating. Thus it comes about that the thought which plunges into the universe must of necessity, even in that very act, remould and re-fashion the universe. Thus Nature perpetually recreates herself by the passion of her children and is forever re-born as the child of her own offspring. But if the supreme difficulty of the art of life lies in the maintenance of this rhythm between these primary attributes, it must never be forgotten that these "attributes" are, after all, only _aspects_ of the soul. The soul _is_ each of them, not _in_ each of them. They are not "faculties" through which the soul acts. They are never absolutely distinct from one another. There is something of each of them in every one of them, and every attempt which they make to establish themselves in an independent existence is only an attempt of the soul itself to live a perverted and a discordant, instead of a natural and a harmonious life.
