Einstein has a feeling for the central order of things. He can detect it in the simplicity of natural laws. We may take it that he felt this simplicity very strongly and directly during his discovery of the theory of relativity. Admittedly, this is a far cry from the contents of religion. I don't believe Einstein is tied to any religious tradition, and I rather think the idea of a personal God is entirely foreign to him.
Wolfgang PauliWhat really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.
Wolfgang PauliWell, our friend Dirac, too, has a religion, and its guiding principle is "God does not exist and Dirac is His prophet."
Wolfgang PauliTo us ... the only acceptable point of view appears to be the one that recognizes both sides of reality-the quantitative and the qualitative, the physical and the psychical-as compatible with each other, and can embrace them simultaneously ... It would be most satisfactory of all if physis and psyche (i.e., matter and mind) could be seen as complementary aspects of the same reality.
