I like to think 'The God Delusion' is a humorous book. I think, actually, it's full of laughs. And people who describe it as a polarizing book or as an aggressive book, it's just that very often they haven't read it.

The body is a survival machine programmed to propagate the genes that reside inside it.

God is the answer to all of those "How must it have come to be" questions.

In medieval times, the Church used to sell 'indulgences' for money. This amounted to paying for some number of days' remission from purgatory, and the Church literally (and with breathtaking presumption) issued signed certificates specifying the number of days off that had been purchased. . . . And of all its money-making rip-offs, the selling of indulgences must surely rank among the greatest con tricks in history. . . .

We, alone on earth, can rebel against the tyranny of the selfish replicators.

But what, after all, is faith? It is a state of mind that leads people to believe something - it doesn't matter what - in the total absence of supporting evidence. If there were good supporting evidence then faith would be superfluous, for the evidence would compel us to believe it anyway. It is this that makes the often-parroted claim that 'evolution itself is a matter of faith' so silly. People believe in evolution not because they arbitrarily want to believe it but because of overwhelming, publicly available evidence.

There is something infantile in the presumption that somebody else has a responsibility to give your life meaning and point… The truly adult view, by contrast, is that our life is as meaningful, as full and as wonderful as we choose to make it.
