the use of a mathematical formula. He has evidently conceived the theory that certain colors are equivalent to certain emotions and by adding or subtracting color he can add or subtract an emotion to or from the spectator. Thus yellow equals joy, but add red to the yellow and the effect will be joy tinged with passion. In this way the fluid motion actuating Kandinsky is bound to be subjected to theoretical treatment instead of being left free to do its own work. The emotion of joy in passing through the painter on its way to the spectator will be subjected to mental checks, with the result that it will be deprived of its greatest value in its original intensity. The study of the aforementioned facts led me in turn to new views on Art, (a) as to the origin and nature of Art, (b) as to the order, intelligibility, and coherence that exist in the natural manifestations of Art, (c) as to the law of growth and progression to be applied to art forms, (d) as to the illumination of this law by a proper standard of criticism. Accordingly I came to see that Art is a potential creative movement in space. It first exists in the fluid motions of the universe and ultimately in a work of art only as the inevitable and efficient expression of itself through a specially adapted medium called the artist. In a metaphysical sense, Art may be said to be a spiritual experience capable of assuming visibility. But it becomes visible only by a process of debasement. Apparently, as I have said, the fluid motion in which Art expresses itself loses its intensity and becomes solid motion in the process of conversion into a work of art, as applied by all civilized artists (as far as we know) up to the present day. In fact, it is only recent years that have witnessed the discovery by the artist of the fluid motion potential in solid motion. Cezanne, Gauguin, and Van Gogh were among the first of the moderns to arrive at the point of realizing this potential character. All three were actively engaged in the refining of solids and suggesting their potential ultimate fluidity. What they actually did was this. They demonstrated that Art is a fluid motion seeking to produce an ultimate creative effect upon the spectator through efficient application, and that fluid motion can only produce its creative effect as fluid motion. Now, largely owing to blindness or wrong direction, artists, with rare exceptions, have hitherto concerned themselves with converting fluid motion into various forms of solid motion. They have in fact stopped at the expression of representative forms of nature and human life, apparently unconscious that in doing so they were not completing the expression of the art flow, but were stopping at a half-way house, so to speak, where of course the maximum creative effect could not be produced. Before this effect can be produced it is necessary to complete the journey by reconverting the solids into fluid motion. It cannot be said that either
