“Do we ever have to abandon all hope? Is it not perhaps a good thing that by refusing to give in to the evidence, the dreams that lie half awake in us all may persist?”

“Emerging from barbarism is a slow process and as man is , geologically speaking, still very young, he has his whole future before him.”

“Modern societies accepted the treasures and the power offered them by science. But they have not accepted - they have scarcely even heard - its profounder message: the defining of a new and unique source of truth, and the demand for a thorough revision of ethical premises, for a complete break with the animist tradition, the definitive abandonment of the 'old covenant', the necessity of forging a new one. Armed with all the powers, enjoying all the riches they owe to science, our societies are still trying to live by and to teach systems of values already blasted at the root by science itself.”

“This country will not be a good place for any of us to live in unless we make it a good place for all of us to live in.”

“We are not called upon to do all the good that is possible, but only that which we can do.”

“Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it... The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game. Is it surprising that, like the person who has just made a million at the casino, we should feel strange and a little unreal?”

“Remember, love is all a woman has to give, but it is the only thing which God permits us to carry beyond the grave.”
