Albert Einstein is often quoted as saying, “God doesn’t play dice with the universe,” as if that meant that he believed in an invisible Heavenly Father taking an interest in our affairs. This longer quotation reflects his actual opinion.
You will hardly find one among the profounder sort of scientific minds without a religious feeling of his own. But it is different from the religiosity of the naive man. For the latter, God is a being from whose care one hopes to benefit and whose punishment one fears; a sublimation of a feeling similar to that of a child for its father, a being to whom one stands, so to speak, in a personal relation, however deeply it may be tinged with awe. But the scientist is possessed by the sense of universal causation… There is nothing divine about morality; it is a purely human affair. His religious feeling takes the form of a rapturous amazement at the harmony of natural law, which reveals an intelligence of such superiority that, compared with it, all the systematic thinking and acting of human beings is an utterly insignificant reflection… It is beyond question closely akin to that which has possessed the religious geniuses of all ages. —Albert Einstein, Mein Weltbild, Amsterdam: Querido Verlag, 1934
