On a recent Sunday evening, Theo came up with an aphorism: the bigger you think, the crappier it looks. Asked to explain he said, "When we go on abou… - Ian McEwan

He had once felt light on the ground. He used to think his life was an open-ended adventure, he used to give things away, it amused him when the unexpected happened, benevolent coincidences used to bear him along. When had all that stopped?

Ian McEwan: I guess my starting point would be: the brain is responsible for consciousness, and we can be reasonably sure that when that brain ceases to be—when it falls apart and decomposes—that will be the end of us. From that, quite a lot of things follow, especially morally. We are the very privileged owners of a brief spark of consciousness, and we therefore have to take responsibility for it. We cannot rely, as Christians or Muslims do, on a world elsewhere, a paradise, to which one can work towards and maybe make sacrifices—and, crucially, make sacrifices of other people. We have a marvellous gift, and you see it develop in children, this ability to become aware that other people have minds just like your own and feelings that are just as important as your own, and this gift of empathy seems to me to be the building block of our moral system. Richard Dawkins: I profoundly agree with you, and I've always felt that one of the things that is wrong with religion is that it teaches us to be satisfied with answers which are not really answers at all. Ian McEwan: And if you have a sacred text that tells you how the world began or what the relationship is between this sky-god and you, it does curtail your curiosity, it cuts off a source of wonder. The loveliness of the world in its wondrousness is not apparent to me in Islam or Christianity and all the other major religions.

This is how the entire course of a life can be changed - by doing nothing.
