I think we have got to start again and go right back to first principles. The argument I shall advance, surprising as it may seem coming from the author of the earlier chapters, is that, for an understanding of the evolution of modern man, we must begin by throwing out the gene as the sole basis of our ideas on evolution. If there is only one Creator who made the tiger and the lamb, the cheetah and the gazelle, what is He playing at? Is he a sadist who enjoys spectator blood sports? ... Is he manuvering to maximize David Attenborough's television ratings?

There does seem to be a sense in which physics has gone beyond what human intuition can understand. We shouldn't be too surprised about that because we're evolved to understand things that move at a medium pace at a medium scale. We can't cope with the very tiny scale of quantum physics or the very large scale of relativity.

... you need more than luck to navigate successfully through a thousand sieves in succession.

The true scientific understanding of the nature of existence is so utterly fascinating; how could you not want people to share it? Carl Sagan, I think, said 'when you're in love, you want to tell the world.' And who, on understanding a scientific view of reality, would not, as it were, fall in love and want to tell the world.

Even if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.

Ideally, I'd like everybody to be secular.

Not a single one of your ancestors died young. They all copulated at least once.
