For this image of an arrow-head of focussed flame which is in constant danger of being dispersed as the flames recede from one another and are blown backwards is only a symbolic way of indicating how difficult it is to pierce with our complicated instrument of research the vast mystery which surrounds us.

All this is mere pictorial metaphor; but in visualizing the human soul as a moving arrow-head, composed of flickering flames that only now and then combine into a sharp point, while at other times the wind drives them apart and bends them back, I am suggesting that the ultimate reality of things is a state of confused movement continually becoming a state of concentrated movement. I am suggesting that the secrets of life only yield themselves up to a movement of desperation. I am suggesting that the spirit of creation is also the spirit of destruction, and that the real object of the energy of creation is to pierce with its burning light the darkness of the objective mystery.

As proof of the necessity of keeping this apex-thought in constant poise, let me reiterate one or two of the philosophical disasters which result from a cessation of its rhythmic function. When the reason, for instance, usurps the whole field and acts in isolation from the imagination and the intuition, it tends to persuade us to deny the very existence of that deepest and most vivid reality of all, the handle of our spear-head, the base of our pyramid, the mysterious entity within us, which we have come, following the traditions of the centuries, to name the "soul." And not only does the soul disappear when the reason thus isolates itself, but another primary revelation of the complex vision, I mean that half-created, half-discovered object of the senses popularly called "matter," disappears with it.

Man's self-consciousness is thus left suspended "in vacuo" with no concrete reality within it and no concrete reality outside it; and "thought-in-the-abstract" becomes the only truth.

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.

The rarity and difficulty of that high art which brings all these orchestral players into harmony is sufficient cause to account for the scarcity of genuine philosophical thought in this confused world. The human soul, looking desperately round for some calm yet passionate light to save its hours from ruinous waste, turns away in bitter disillusion from the thin dust and the swollen vapour that are offered it.

Out of the logical laboratories of the abstract reason this thin dust is offered; and out of the ideal factories of the wish for superficial comfort this iridescent vapour is poured forth. That burning secret of life, that lovely and terrible reality for which the soul pines is not to be found in any mere outward fact or in any mere subjective intuition.
