The laws of nature, dear boy, the laws of nature. And I do not, unlike you, require a God Of The Gaps to formulate them. In other words, I do not need to try to explain the difficult stuff, though it's stuff we are closing in on, with the utterly and eternally inexplicable. Basically because, unlike you, I am neither mad nor utterly deluded. Do try not to bother me. You will find far more fertile ground with other targets. You really are a very slow learner, aren't you?
