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.
Our friend Dirac has a creed; and the main tenet of that creed is: There is no God, and Dirac is his prophet.
A synthesis embracing both rational understanding and the mystical experience of unity is the mythos, spoken or unspoken, or our present day and age.
