The idea of a universal mind or Logos would be, I think, a fairly plausible inference from the present state of scientific theory.

It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.

Schrödinger's wave-mechanics is not a physical theory, but a dodge - and a very good dodge too.

In the world of physics we watch a shadowgraph performance of the drama of familiar life. The shadow of my elbow rests on the shadow table as the shadow ink flows over the shadow paper. It is all symbolic, and as a symbol the physicist leaves it. ... The frank realisation that physical science is concerned with a world of shadows is one of the most significant of recent advances.
