The supreme unity, therefore, in this complicated world, thus revealed to us by the activity of the complex vision is the unity of time and space. This unity is eternally reborn and eternally re-discovered every time any living personality contemplates the system of things. And since "the sons of the universe" must be regarded as continually contemplating the system of things, struggling with it, moulding it, and changing it, according to their pre-existent ideal, we are compelled to assume that time and space are eternal aspects of reality and that their eternal necessity gives the system of things its supreme unity.

No isolated speculation of the logical reason, functioning apart from the other attributes of the complex vision, can undermine this supreme unity of time and space. The "a priori unity of apperception" is an unreality compared with this reality. The all-embracing cosmic "monad," contemplating itself as its eternal object, is an unreality compared with this reality.

We are left with a pluralistic world of individual souls, finding their pattern and their ideal in the vision of the "immortal gods" and perpetually rediscovering and recreating together "a universe" which like themselves is dominated by time and space and which like themselves is for ever divided against itself in an eternal and unfathomable duality.

The ultimate truth of the system of things according to the revelation of the complex vision is thus found to consist in the mystery of personality confronting "something" which seems impersonal. Over both these things, over the personal soul and over the primordial "clay" or "energy" or "movement" or "matter" out of which the personal soul creates its "universe," time and space are dominant. But since we can predicate nothing of this original "plasticity" except that it is "plastic" and that time and space rule over it, it is in a strict sense illegitimate to say that this primordial "clay" or "world stuff" is in itself divided into a duality. We know nothing, and can never know anything about it, beyond the bare fact of its existence. Its duality comes from the duality in us. It is we who create the contradiction upon which its life depends. It is from the unfathomable duality in the soul of the "companions of men" that the universe is brought forth.

The ultimate duality which perpetually creates the world is the ultimate duality in all living souls and in the souls of "the sons of the universe." But although it is we ourselves who in the primal act of envisaging the world endow it with this duality, it would be an untrue statement to say that this duality in the material universe is an "illusion." It is no more an illusion than the objective material world itself is an illusion. Both are created by the inter-action between the mystery of personality and the mystery of what seems the impersonal. Thus it remains perfectly true that what we sometimes call "brute matter" possesses an element of malignant inertness and malicious resistance to the power of creation. This malice of the impersonal, this malignant inertness of "matter," is an ultimate fact; and is not less a fact because it depends upon the existence of the same malice and the same inert resistance in our own souls.

Nor are we able to escape from the conclusion that this malignant element in the indefinable "world-stuff" exists independently of any human soul. It must be thought of as dependent upon the same duality in the souls of "the sons of the universe" as that which exists in the souls of men. For although the primordial ideas of truth and nobility and beauty, brought together by the emotion of love, are realized in the "gods" with an incredible and immortal intensity, yet the souls of the "gods" could not be souls at all if they were not subject to the same duality as that which struggles within ourselves.

It follows from this that we are forced to recognize the presence of a potentiality of evil or malice in the souls of "the sons of the universe." But although we cannot escape from the conclusion that evil or malice exists in the souls of the immortals as in all human souls, yet in their souls this evil or malice must be regarded as perpetually overcome by the energy of the power of love. This overcoming of malice by the power of love, or of evil by "good," in the souls of "the sons of the universe," must not be regarded as a thing once for all accomplished, but as a thing eternally re-attained as the result of an unceasing struggle, a struggle so desperate, so passionate and so unfathomable, that it surpasses all effort of the mind to realize or comprehend it.

It must not, moreover, be forgotten that what the complex vision reveals about this eternal struggle between love and malice in the souls of "the sons of the universe" and in the souls of all living things, is not that love and malice are vague independent elemental "forces" which obsess or possess or function through the soul which is their arena, but rather that they themselves are the very stuff and texture and essence of the individual soul itself.

Their duality is unfathomable because the soul is unfathomable. The struggle between them is unfathomable because the struggle between them is nothing less than the intrinsic nature of the soul. The soul is unthinkable without this unfathomable struggle in its inherent being between love and malice or between life and what resists life. We are therefore justified in saying that "the universe" is created by the perpetual struggle between love and malice or between life and what resists life. But when we say this we must remember that this is only true because "the universe" is half-discovered and half-created by the souls of "the sons of the universe" and by the souls of all living things which fill the universe. This unfathomable duality which perpetually re-creates Nature, does not exist in Nature apart from living things, although it does exist in nature apart from any individual living thing.

All those aspects of the objective universe which we usually call "inanimate," such as earth, water, air, fire, ether, electricity, energy, movement, matter and the like, including the stellar and planetary bodies and the chemical medium, whatever it may be, which unites them, must be regarded as sharing, in some inscrutable way, in this unfathomable struggle. We are unable to escape from this conception of them, as thus sharing in this struggle, because they are themselves the creation and discovery of the complex vision of the soul; and the soul is, as we have seen, dependent for its every existence upon this struggle.
