Einstein's God was not the God of most other men. When he wrote of religion, as he often did in middle and later life, he tended to adopt the belief of Alice's Red Queen that "words mean what you want them to mean," and to clothe with different names what to more ordinary mortals and to most Jews looked like a variant of simple agnosticism. Replying in 1929 to a cabled inquiry from Rabbi Goldstein of New York, he said that he believed "in Spinoza's God who reveals himself in the harmony of all that exist, not in a God who concerns himself with the fate and actions of men." And it is claimed that years later, asked by Ben-Gurion whether he believed in God, "even he, with his great formula about energy and mass, agreed that there must be something behind the energy." No doubt. But much of Einstein's writing gives the impression of belief in a God even more intangible and impersonal than a celestial machine minder, running the universe with indisputable authority and expert touch. Instead, Einstein's God appears as the physical world itself, with its infinitely marvelous structure operating at atomic level with the beauty of a craftsman's wristwatch, and at stellar level with the majesty of a massive cyclotron. This was belief enough. It grew early and rooted deep. Only later was it dignified by the title of cosmic religion, a phrase which gave plausible respectability to the views of a man who did not believe in a life after death and who felt that if virtue paid off in the earthly one, then this was the result of cause and effect rather than celestial reward. Einstein's God thus stood for an orderly system obeying rules which could be discovered by those who at the courage, imagination, and persistence to go on searching for them. It was to this past which he began to turn his mind soon after the age of twelve. The rest of his life everything else was to seem almost trivial by comparison.
