Hi.
I have indeed read the Wilber book. I agree with you that quantum physics (or for that matter any science?) cannot prove a spiritual/mystical worldview but, as you say, it can suggest it and opens the door. As I said in the article, it is not the actual physics/science that is relevant but the philosophical statements made by the physicists based on their work. Can we take these seriously or not?
Unlike you (at least at the moment unless I can persuade you) I lean against Wilber. I wrote a critique of his book here:
Quantum Physics, Spirituality — part 6, Ken Wilber | by Graham Pemberton | Medium
Interestingly and ironically, a few years later Norman Friedman wrote Bridging Science and Spirit, with the subtitle Common Elements in David Bohm’s Physics, The Perennial Philosophy and Seth, choosing Wilber as his spokesperson for the Perennial Philosophy, and making observations about the numerous similarities between their viewpoints.
That is a quote from the following article in the series:
Quantum Physics and Spirituality — part 7, David Bohm | by Graham Pemberton | Medium
