“The foundation of all understanding of sociological theory — that is to say, of all understanding of human life — is that is no static maintenance of perfection is possible. This axiom is rooted in the nature of things. Advance or Decadence are the only choices offered to mankind. The pure conservative is fighting against the essence of the universe. (…) The doctrine is founded upon three metaphysical principles. One principle is that the very essence of real actuality — that is of the complete real — is process.”

Alfred North Whitehead, Adventures of Ideas, The Free Press, NY, 1967 (1931). p. 274.
