I believe in transhumanism: once there are enough people who can truly say that, the human species will be on the threshold of a new kind of existence, as different from ours as ours is from that of Peking man. It will at last be consciously fulfilling its real destiny.

We should be agnostic about those things for which there is no evidence. We should not hold beliefs merely because they gratify our desires for afterlife, immortality, heaven, hell, etc.

But if God and immortality be repudiated, what is left? That is the question usually thrown at the atheist's head. The orthodox believer likes to think that nothing is left. That, however, is because he has only been accustomed to think in terms of his orthodoxy. In point of fact, a great deal is left.That is immediately obvious from the fact that many men and women have led active, or self-sacrificing, or noble, or devoted lives without any belief in God or immortality. Buddhism in its uncorrupted form has no such belief; nor did the great nineteenth-century agnostics; nor do the orthodox Russian Communists; nor did the Stoics. Of course, the unbelievers have often been guilty of selfish or wicked actions; but so have the believers. And in any case that is not the fundamental point. The point: is that without these beliefs men and women may yet possess the mainspring of full and purposive living, and just as strong a sense that existence can be worth while as is possible to the most devout believers.

By death the moon was gathered in Long ago, ah long ago;Yet still the silver corpse must spinAnd with another's light must glow.Her frozen mountains must forgetTheir primal hot volcanic breath,Doomed to revolve for ages yet,Void amphitheatres of death.And all about the cosmic sky,The black that lies beyond our blue,Dead stars innumerable lie,And stars of red and angry hueNot dead but doomed to die.

Many people assert that this abandonment of the god hypothesis means the abandonment of all religion and all moral sanctions. This is simply not true. But it does mean, once our relief at jettisoning an outdated piece of ideological furniture is over, that we must construct something to take its place.

Evolution... is the most powerful and the most comprehensive idea that has ever arisen on Earth.

There is no separate supernatural realm: all phenomena are part of one natural process of evolution.

As I see it the world is undoubtedly in need of a new religion, and that religion must be founded on humanist principles. When I say religion, I do not mean merely a theology involving belief in a supernatural god or gods; nor do I mean merely a system of ethics, however exalted; nor only scientific knowledge, however extensive; nor just a practical social morality, however admirable or efficient. I mean an organized system of ideas and emotions which relate man to his destiny, beyond and above the practical affairs of every day, transcending the present and the existing systems of law and social structure. The prerequisite today is that any such religion shall appeal potentially to all mankind; and that its intellectual and rational sides shall not be incompatible with scientific knowledge but on the contrary based on it.

I recall the story of the philosopher and the theologian... The two were engaged in disputation and the theologian used the old quip about a philosopher resembling a blind man, in a dark room, looking for a black cat — which wasn't there. ‘That may be,’ said the philosopher, ‘but a theologian would have found it.

It is easier to believe that there was nothing before there was something than that there was something before there was nothing.

By speech first, but far more by writing, man has been able to put something of himself beyond death. In tradition and in books an integral part of the individual persists, for it can influence the minds and actions of other people in different places and at different times: a row of black marks on a page can move a man to tears, though the bones of him that wrote it are long ago crumbled to dust. In truth, the whole progress of civilization is based upon this power.

To speculate without facts is to attempt to enter a house of which one has not the key, by wandering aimlessly round and round, searching the walls and now and then peeping through the windows. Facts are the key.
