Psychogenesis has led to man. Now it effaces itself, relieved or absorbed by another and a higher function-the engendering and subsequent development of the mind, in one word noogenesis. When for the first time in a living creature instinct perceived itself in its own mirror, the whole world took a pace forward.
Pierre Teilhard de ChardinDriven by the forces of love, the fragments of the world seek each other so that the world may come into being. ... the universal gravity of bodies, ... is merely the reverse or shadow of that which really moves nature. Love in all its subtleties is nothing more, and nothing less, than the more or less direct trace marked on the heart of the element by the psychical convergence of the universe upon itself.
