Gurdjieff, Part 4:

Every branch of science endeavors to elaborate and to establish an exact language for itself. But there is no universal language. For exact understanding exact language is necessary.… This new language is based on the principle of relativity; that is to say, it introduces relativity into all concepts and thus makes possible an accurate determination of the angle of thought—making it possible to establish at once what is being said, from what point of view and in what connection. In this new language all ideas are concentrated round one idea. This central idea is the idea of evolution … and the evolution of man is the evolution of his consciousness.

G. I. Gurdjieff, paraphrased from page 70 of IN SEARCH OF THE MIRACULOUS
