At the age of eighteen ... I read Mill's Autobiography, where I found a sentence to the effect that his father taught him that the question 'Who made me?' cannot be answered, since it immediately suggests the further question 'Who made God?'. This led me to abandon the 'First Cause' argument, and to become an atheist. Throughout the long period of religious doubt, I had been rendered very unhappy by the gradual loss of belief, but when the process was completed, I found to my surprise that I was quite glad to be done with the whole subject. - Bertrand Russell [ more quotes ] Autobiography
