Bill asks about whether evolution and the randomness it seems to imply are problematic for faith. Paul discusses the difference between evolution in biology (with a succession of species) and physics (where new laws layer on top of old laws without destroying them). We talk about the mindsets of physicists and biologists, and tangle more with that problematic phrase "shades of gray." Bill confronts Paul with Einstein's comment that "God does not play dice," and Paul responds with commentary mostly from Harvey Brown and Steven Barr about the alternative interpretations of quantum theory: hidden variables and determinism, or the Copenhagen sense that the probabilistic interpretation of quantum events is physically, ontologically, metaphysically real, and the room in the Copenhagen interpretation for interactions between the spiritual (souls, God) and the physical (body, miracles).
