Primitives produce art because they must; they have no other motive than a passionate desire to express their sense of form. Untempted, or incompetent, to create illusions, to the creation of form they devote themselves entirely. Presently, however, the artist is joined by a patron and a public, and soon there grows up a demand for "speaking likenesses." While the gross herd still clamours for likeness, the choicer spirits begin to affect an admiration for cleverness and skill. The end is in sight. In Europe we watch art sinking, by slow degrees, from the thrilling design of Ravenna to the tedious portraiture of Holland, while the grand proportion of Romanesque and Norman architecture becomes Gothic juggling in stone and glass. Before the late noon of the Renaissance art was almost extinct. Only nice illusionists and masters of craft abounded. That was the moment for a Post-Impressionist revival.
For various reasons there was no revolution. The tradition of art remained comatose. Here and there a genius appeared and wrestled with the coils of convention and created significant form. For instance, the art of Nicolas Poussin, Claude, El Greco, Chardin, Ingres, and Renoir, to name a few, moves us as that of Giotto and Cézanne moves. The bulk, however, of those who flourished between the high Renaissance and the contemporary movement may be divided into two classes, virtuosi and dunces. The clever fellows, the minor masters, who might have been artists if painting had not absorbed all their energies, were throughout that period for ever setting themselves technical acrostics and solving them. The dunces continued to elaborate chromophotographs, and continue.
The fact that significant form was the only common quality in the works that moved me, and that in the works that moved me most and seemed most to move the most sensitive people--in primitive art, that is to say--it was almost the only quality, had led me to my hypothesis before ever I became familiar with the works of Cézanne and his followers. Cézanne carried me off my feet before ever I noticed that his strongest characteristic was an insistence on the supremacy of significant form. When I noticed this, my admiration for Cézanne and some of his followers confirmed me in my aesthetic theories. Naturally I had found no difficulty in liking them since I found in them exactly what I liked in everything else that moved me.
