Why I Am Not a Christian

...than people thought, and that the laws at which you arrive are statistical averages of just the sort that would emerge from chance. There is, as we all know, a law that if you throw dice you will get double sixes only about once in thirty-six times, and we do not regard that as evidence that the fall of the dice is regulated by design; on the contrary, if the double sixes came every time, we should think that there was design. The laws of nature are of that sort as regards a great many of them. They are statistical averages such as would emerge from the laws of chance; and that makes this whole business of natural law much less impressive than it formerly was.

Quite apart from that, which represents the momentary state of science that may change tomorrow, the whole idea that natural laws imply a law-giver is due to a confusion between natural and human laws. Human laws are commands telling you to behave in a certain way—in which way you may choose to behave, or you may choose not to behave; but natural laws are a description of how things do in fact behave, and, being a mere description of what they in fact do, you cannot argue that there must be somebody who told them to do that. Even supposing that there were, you are then faced with the question, "Why did God issue just those natural laws and no others?" If you say that he did it simply from his own good pleasure, and without any reason, you then find that there is something which is not subject to law, and so your train of natural law is interrupted.
