This fundamental discovery that all bodies owe their origin to arrangements of single initial corpuscular type is the beacon that lights the history of the universe to our eyes. In its own way, matter obeyed from the beginning that great law of biology to which we shall have to recur time and time again, the law of "complexification."

Man only progresses by slowly elaborating from age to age the essence and the totality of a universe deposited within him.

You have told me, O God, to believe in hell. But you have forbidden me to think...of any man as damned

The past has revealed to me the structure of the future.
