That there is a continuous link from humans to gorillas, with the intermediate species merely long dead, is beyond the understanding of speciesists. Tie the label Homo sapiens even to a tiny piece of insensible embryonic tissue, and its life suddenly leaps to infinite, incomputable value.... Self-styled pro-lifers, and others that indulge in footling debates about exactly when in its development a foetus becomes human, exhibit the same discontinuous mentality. Human, to the discontinuous mind, is an absolutist concept. There can be no half measures. And from this flows much evil.

We need a name for the new replicator, a noun that conveys the idea of a unit of cultural transmission, or a unit of imitation. 'Mimeme' comes from a suitable Greek root, but I want a monosyllable that sounds a bit like 'gene'. I hope my classicist friends will forgive me if I abbreviate mimeme to meme. If it is any consolation, it could alternatively be thought of as being related to 'memory', or to the French word même. It should be pronounced to rhyme with 'cream'.

The argument from improbability, properly deployed, comes close to proving that God does not exist.

I could easily believe that religion could enhance health and hence survival, and that therefore there could be indeed be literally Darwinian survival value, Darwinian selection in favor of religion. None of that of course bears at all upon the truth value of the claims made by religions.

My passion is for scientific truth. I don't much care about good and evil. ... I care about what's true.

Bertrand Russell used a hypothetical teapot in orbit about Mars for the same didactic purpose. You have to be agnostic about the teapot, but that doesn't mean you treat the likelihood of its existence as being on all fours with its non-existence.

What has happened is that genetics has become a branch of information technology. It is pure information. It's digital information. It's precisely the kind of information that can be translated digit for digit, byte for byte, into any other kind of information and then translated back again. This is a major revolution. I suppose it's probably "the" major revolution in the whole history of our understanding of ourselves. It's something would have boggled the mind of Darwin, and Darwin would have loved it, I'm absolutely sure.
