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. The complex vision, with its rhythmic apex-thought, is not really a "pyramid" or a "wedge of flame" any more than it is a circle or a cube or a square or an "a priori synthetic unity of apperception" or "an universal self-conscious monad." It is the vision of a living personality, surrounded by an unfathomable universe. To keep our thoughts firmly and harmoniously fixed on the real objective spectacle of life and on the real subjective "soul," or personality, contemplating this spectacle, it is advisable to revert to the magical and mysterious associations called up by the classical word _Nature_. The mere utterance of the word "Nature" serves to bring us back to the things which are essential and organic, and to put into their proper place of comparative unreality all these "unities" and circles, all these pyramids and "monads." When we think of the astounding beauty and intricacy of the actual human body; when we think of the astounding beauty and intricacy of the actual living soul which animates this body, and when we think of the magical universe which surrounds them both, we are compelled to recognize that in the last resort Nature herself is the great mystery. The word "Nature" conveys a more living and less metaphysical connotation than the word "universe," and may be regarded as implying more of that in-determined future of all living souls, which is still in the process of creation. The "universe" is a static conception. Nature is a dynamic conception. When we speak of Nature we think of the whole struggle towards a fuller life of all the living entities which the indefinable medium of the universe contains. Nature from this point of view becomes the whole unfathomable spectacle, seen as something living and growing and changing.
