But because, within time and space, the universe is unfathomable, and because, also within time and space, personality is unfathomable, the "substratum" of the soul, which is the point where the known and the unknown meet, must be unfathomable also, and hence must sink away beyond the limit of our thought and beyond the limit of our sensation.

Since it does this, since it sinks away beyond the limit of our thought, it must be regarded as "something" whose reality is partly known and partly unknown. Thus it is true to say that the "substratum" of the soul is and is not a portion of the objective universe. The substratum of the soul is, in fact, the essential and ultimate reality, where all that we know loses itself in all that we do not know. Because we are compelled to admit that only one aspect of the "substratum" of the soul is a portion of the objective universe as we know it, this does not justify us in asserting that the "substratum" of the soul is at once within space and time and outside of space and time.

Nothing is outside of space and time. This conception of "outside" is, as we have seen, an abstraction evoked by the isolated activity of the logical reason. The fact that only one aspect of the "substratum" of the soul—and even that one with the barest limit of definition—can be regarded as a portion of the objective universe does not give the soul any advantage over the universe. For the universe, like the soul, has also its unfathomable depths. That indefinable medium, for instance, which we are compelled to think of as making it possible that various souls should touch one another and communicate with one another, is in precisely the same position as regards any ultimate analysis as is the soul itself. It also sinks away into unfathomableness. It also becomes a portion of that part of reality which we do not know.

At this point in our enquiry it is not difficult to imagine some materialistic objector asking the question how we can conceive such a vaguely denned entity as the soul possessing such very definite attributes as those which make up the complex vision.

Is it not, such an one might ask, a fantastic and ridiculous assumption to endow so obscure a thing as this "soul" with such very definite powers as reason, instinct, will, intuition, imagination, and the rest? Surely, such an one might protest, it is in the physical body that these find their unity? Surely, if we must have a meeting-place where thought and the objects of thought lose themselves in one another, such a meeting-place can be nothing else than the cells of the brain?

The answer to this objection seems to me quite a final one. The physical body cannot supply us with the true meeting-place between "the life of thought" and "the life of sensation" because the physical body does not in itself sink away into unfathomablenesss as does the substratum of the soul. The physical body can only be regarded as unfathomable when definitely included in the whole physical universe. But the substratum of the soul is doubly unfathomable. It is unfathomable as being the quintessence or vanishing-point of "matter" or "energy," and it is unfathomable as being the quintessence of that personal self which confronts not only the objective universe but the physical body also as part of that universe. It is undoubtedly true that this real self which is the centre of its own universe is bound to contemplate itself as occupying a definite point in space and time.

This is one of its eternal contradictions; that it should be at the same time the creator of its universe and an unfathomable portion of the very universe it creates. The answer which the philosophy of the complex vision makes to the materialistic questioner who points to the "little cells of the brain" may be briefly be put thus.

The soul functions through the physical body and through the cells of the brain. The soul is so closely and so intimately associated with the physical body that it is more than possible that the death of the physical body implies the annihilation of the soul. But when it comes to the question as to where we are to look for the essential self in us which is able to say "I am I" it is found to be much more fantastic and ridiculous to look for it in the "little cells of the brain" than in some obscure "something," or "vanishing point of sensation," where mind and matter are fused together. That this "something" which is able to say "I am I" should possess instinct, reason, will, intuition, conscience and the rest, may be hard to imagine. But that the "little cells of the brain" should possess these is not only hard to imagine—it is unimaginable. The mysterious relation which exists between our soul and our body lends itself to endless speculation; and much of this speculation tends to become far more fantastic and ridiculous than any analysis of the attributes of the soul. Experiment and experience alone can teach us how far the body is actually malleable by the soul and amenable to the soul's purpose.

The arbitrary symbol which I have made use of to indicate the nature of the soul's essential reality, the image of a pyramidal wedge of flames, is certainly felt to be but a thin and rigid fancy when we consider how in the actual play of life the soul expresses itself through the body.

As I have already indicated, the original revelation of the complex vision accepts without scruple the whole spectacle of natural life. The philosophy of the complex vision insists that no rationalistic necessity of pure logic gives it the right to reject this natural objective spectacle. The philosophy of the complex vision insists that this obvious, solid, external, so-called "materialistic" spectacle of common life, be accepted, included and continually returned to. It insists that the word "illusion" be no more used about this spectacle. It insists that this vast unfathomable universe of time and space be recognized as an ultimate reality, and that all these projected images of the pure reason, all these circles, cubes, squares and straight lines, all these "unities of apperception," universal "monads" and the like, be recognized as by-products of the abstracting energy of human logic and as entirely without reality when compared with this objective spectacle. My own symbolic or pictorial image of the activity of the complex vision, this pyramidal wedge or arrow-head of concentrated and focussed flames, must be recognized as no more adequate or satisfactory than any of these.
