It has been necessary to consider these ultimate movements of the soul in order that we may be in a position to understand the general nature of this mysterious thing we call "art," and be able to track its river-bed, so to speak, up to the original source. From a consideration of the fact that the outflowing of the soul takes the form of emotion, and that this emotion is at perpetual war within itself and is for ever contradicting itself, we arrive at our first axiomatic principle with regard to art, namely that art is, and must always be, penetrated through and through by the spirit of contradiction. Whatever else art may become, then, one thing we can predicate for certain with regard to it, namely that it springs from an eternal conflict between two irreconcilable opposites. We are, further than this, able to define the nature of these opposites as the everlasting conflict between creation and what resists creation, or between love and malice. It is just here, in regard to the character of these opposites, that the philosophy of the complex vision differs from the Bergsonian philosophy of the "élan vital." According to Bergson's monistic system the only genuine reality is the flux of spirit The spirit of some primordial self-expansion projects what we call "matter" as its secondary manifestation and then is condemned to an unending and exhausting struggle with what it has projected. Spirit, therefore, is pure energy and movement and matter is pure heaviness and resistance. Out of the necessity of this conflict emerge all those rigid logical concepts and mathematical formulae, of which space and time, in the ordinary sense of those words, are the ultimate generalization. Our criticism of this theory is that both these things--this "spirit" and this spirit-evoked "matter"--are themselves meaningless concepts, concepts which, in spite of Bergson's contempt for ordinary metaphysic, are in reality entirely metaphysical, being in fact, like the old-fashioned entities whose place they occupy, nothing but empty bodiless generalizations abstracted from the concrete living reality of the soul. But quite apart from our criticism of the Bergsonian "spirit" and "matter" on the ground of their being unreal conceptions illegitimately abstracted from real personality we are compelled to note a second vivid difference between our point of view and his in regard to this matter of opposites and their contradiction. Bergson's monism, as we have seen, resolves itself into a duality which may be defined as conscious activity confronted by unconscious inertness.
