“Many think that Cubism is an art of transition, an experiment which is to bring ulterior results. Those who think that way have not understood it. Cubism is not either a seed or a foetus, but an art dealing primarily with forms, and when a form is realized it is there to live its own life. A mineral substance, having geometric formation, is not made so for transitory purposes, it is to remain what it is and will always have its own form. p. 323.”
