This beautiful passage was written by Christopher Hitchens before he found out he had cancer, in The Portable Atheist. I think it’s quite profound and true:
Death is certain, replacing both the siren-song of Paradise and the dread of Hell. Life on this earth, with all its mystery and beauty and pain, is then to be lived far more intensely: we stumble and get up, we are sad, confident, insecure, feel loneliness and joy and love. There is nothing more; but I want nothing more.
Nor do I.
