Quantum physicist Erwin Schrödinger often wrote about philosophy and religion (his personal beliefs corresponded to some form of
Vedanta) but surprisingly none of his musings on these topics include any trace of quantum theory. For Schrödinger physics and religion were completely separate. However in one instance, which deserves to be better known, Schrödinger produced a three-line logical proof of the existence of God based not on quantum theory but on the more general Materialist Assumption that the universe is completely describable by materialist laws. In the tradition of Aristotle, Aquinas and Anselm, here is Schrödinger's Proof for the Existence of God:
1. My body functions as a pure mechanism according to the laws of nature (Materialist Assumption).
2, Yet I know by direct and incontrovertible experience that I am directing its motions, of which I correctly foresee the effects.
3. Conclusion: I am the Person who controls the motions of the atoms according to the Law of Nature = I am God.
