A virgin can conceive. A dead body can walk again. Your leprosy can be cured. The blind can see. Nonsense. It’s not moral to lie to children. It’s not moral to lie to ignorant, uneducated people and tell them that if they only would believe nonsense, they can be saved. It’s immoral.

Religion comes from the period of human prehistory where nobody - not even the mighty Democritus who concluded that all matter was made from atoms - had the smallest idea of what was going on. It comes from the bawling and fearful infancy of our species, and is a babyish attempt to meet our inescapable demand for knowledge. Today the least educated of my children knows much more about the natural order than any of the founders of religion.

Chemotherapy isn't good for you. So when you feel bad, as I am feeling now, you think, 'Well that is a good thing because it's supposed to be poison. If it's making the tumor feel this queasy, then I'm OK with it.'

You know, you can make a small mistake in language or etiquette in Britain, or you could when I was younger, and really be made to feel it, and it's the flick of a lash, but it would sting, and especially at school where there's not much privacy, and so on. You could, yes, undoubtedly be made to feel crushed.

People until I was 60 would always say they thought I looked younger, which I think, without flattering myself, I did, but I think I certainly have, as George Orwell says people do after a certain age, the face they deserve.

Our weapons are the ironic mind against the literal: the open mind against the credulous; the courageous pursuit of truth against the fearful and abject forces who would set limits to investigation (and who stupidly claim that we already have all the truth we need). Perhaps above all, we affirm life over the cults of death and human sacrifice and are afraid, not of inevitable death, but rather of a human life that is cramped and distorted by the pathetic need to offer mindless adulation, or the dismal belief that the laws of nature respond to wailings and incantations.

For the people who ostensibly wish me well or are worried about my immortal soul, I say I take it kindly.
