Cubism, essentially intellectual in its nature, has a well-articulated system of principles and is supported by a goodly amount of analytic reasoning. Cubism begins by a rather conservative revision of an academic formula. The academic picture shows as many facets of an object as can be seen at one glance. Cubism assumes it to be perfectly logical to show more, its back and bottom along with its sides and front; its internal structure along with its external aspect. The Cubists took the method early under control.
