It is immoral to brand children with religion. 'This is a Catholic child.' 'That is a Muslim child.' I want everyone to flinch when they hear such a phrase, just as they would if they heard, 'That is a Marxist child.'

I need to learn not to bend over backwards to be nice to faith-heads. Give these people an inch and they take a league. I think, as I did when I wrote The God Delusion, that the Roman Catholic Church is a disgusting institution, the second most evil religion in the world.

The machine code of the genes is uncannily computer-like. Apart from differences in jargon, the pages of a molecular biology journal might be interchanged with those of a computer engineering journal.

I'm easily persuaded that a really good novelist who gets inside somebody else's head could be serving a valuable purpose. I enjoy satirical novels that take a wry, humorous, ironic look at modern life.

With so many mind-bytes to be downloaded, so many mental codons to be replicated, it is no wonder that child brains are gullible, open to almost any suggestion, vulnerable to subversion, easy prey to Moonies, Scientologists and nuns. Like immune-deficient patients, children are wide open to mental infections that adults might brush off without effort.

In the case of Stalinism, people actually distorted science, because it was for the good of the Communist Party.

We have the same genetic code for all living creatures. We have a large number of genes that are manifestly the same, but with detail differences - they look like different drafts of the same book. In extreme cases, like a human and a beetroot, it's like the difference between Matthew and Luke's Gospel - clearly they tell the same story, but with different words. Whereas with a human and a chimp, it's like two different printings of Matthew, with a few typos in one.
