“To become aware of what is constant in the flux of nature and life is the first step in abstract thinking. The recognition of regularity in the courses of the heavenly bodies and in the succession of seasons first provides a basis for a systematic ordering of events, and this knowledge makes possible a calendar. ... Simultaneously with this concept, a system of relationships comes into the idea of the world. Change is not something absolute, chaotic, and kaleidoscopic; its manifestation is a relative one, something connected with fixed points and a given order.”

“It is the business of man to become acquainted with the material universe in all of its manifestations, so far as may be possible, in order to provide a foundation of knowledge on which the reasoning mind of man may increasingly build.”

“Philosophy arises from an unusually obstinate attempt to arrive at real knowledge. What passes for knowledge in ordinary life suffers from three defects: it is cocksure, vague and self-contradictory. The first step towards philosophy consists in becoming aware of these defects, not in order to rest content with a lazy scepticism, but in order to substitute an amended kind of knowledge which shall be tentative, precise and self-consistent.”

“Dance first. Think later. It's the natural order.”

“The ancient Ionians were the first we know of to argue systematically that laws and forces of Nature, rather than gods, are responsible for the order and even the existence of the world.”

“The attitude that nature is chaotic and that the artist puts order into it is a very absurd point of view, I think. All that we can hope for is to put some order into ourselves”
