Quotes from different smart people:

I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but Im not absolutely sure of anything, and in many things I dont know anything about, such as whether it means anything to ask why were here, and what the question might mean. I might think about a little, but if I cant figure it out, then I go to something else. But I dont have to know an answer. I dont feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesnt frighten me.
-- Richard Feynman

"[I] think it would be a real cultural deprivation if everyone could not share the mystery and wonder of the cosmos that modern science reveals to us the emergence, from simple beginnings, of stars and planets, and the intricate evolution on Earth of life and intelligence."

I think the odds are no better than fifty-fifty that our present civilisation on Earth will survive to the end of the present century. Our choices and actions could ensure the perpetual future of life (not just on Earth, but perhaps far beyond it, too). Or in contrast, through malign intent, or through misadventure, twenty-first century technology could jeopardise lifes potential, foreclosing its human and posthuman future. What happens here on Earth, in this century, could conceivably make the difference between a near eternity filled with ever more complex and subtle forms of life and one filled with nothing but base matter.

The first aquatic creatures crawled onto dry land in the Silurian era, more than three hundred million years ago. They may have been unprepossessing brutes, but had they been clobbered, the evolution of land-based fauna would have been jeopardised. Likewise, the post-human potential is so immense that not even the most misanthropic amongst us would countenance its being foreclosed by human actions.

-- Lord Martin Rees

The importance of the Scientific Revolution for philosophy is beyond question. Modern philosophy the work of both rationalists and empiricists would have been impossible without great advances in physics. Analogously, therefore, we could anticipate that the Darwinian Revolution will have important implications for philosophy. Indeed, I would go further and say that we might expect Darwin's work to have even greater implications for philosophy than those of physics. The theory of evolution through natural selection impinges so directly on our own species. It is not just that we are on a speck of dust whirling around in the void but that we ourselves are no more than transformed apes. If such a realization is not to affect our views of epistemology and ethics, I do not know what is. As I said in the Preface, I find it inconceivable that it is irrelevant to the foundations of philosophy whether we are the end result of a slow natural evolutionary process, or made miraculously in Gods own image on a Friday, some 6,000 years ago.

--Michael Ruse


Brief and powerless is man's life; on him and all his race the slow, sure doom falls pitiless and dark. Blind to good and evil, reckless of destruction, omnipotent matter rolls on its relentless way.




It appears that during those ages when animals were torturing each other with ferocious horns and agonizing stings, Omnipotence was quietly waiting for the ultimate emergence of man, with his still more widely diffused cruelty. Why the Creator should have preferred to reach his goal by a process, instead of going straight to it, these modem theologians do not tell us.

Such, in outline, but even more purposeless, more void of meaning, is the world which Science presents for our belief. Amid such a world, if anywhere, our ideals henceforward must find a home. That Man is the product of causes which had no prevision of the end they were achieving; his origin, his growth, his hopes and fears, his loves and his beliefs, are but the outcome of accidental collocations of atoms; that no fire, no heroism, no intensity of thought and feeling, can preserve an individual life beyond the grave; that all the labours of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system, and that the whole temple of Man's achievement must inevitably be buried beneath the debris of a universe in ruins.

--Bertrand Russell
