Here's a delightful excerpt from the interview but you should really go there and read the entire thing:
I wish there were more celebrities were open and honest about their atheism or agnosticism.Did you lose your faith or never have any?I used to believe in God. The Christian one, that is. (There are a few thousand to choose from. But I was born in a country where the dominant religion was Christianity so I believed in that one. Isn't it weird how that always happens?) Luckily I was also interested in science and nature. And reason and logic. And honesty and truth. And equality and fairness. By the age of eight I was an atheist. (That word shouldn’t even exist. It shouldn’t be needed. But it does. And it is.)You studied philosophy at university – which philosophical idea has turned out to be most useful?A few spring to mind. Bertrand Russell said, “No one gossips about other people’s secret virtues.” That became more profound once I’d become famous. Ha Ha. And I love “There is no god higher than truth” – Mahatma Gandhi.
