No problem with what you say here although, as you know, I see dual aspect monism as a watered down version of idealism. I think in one of your posts you described it as believing that mind and matter emerge from a physically and mentally neutral source. This is somewhat vague. Unless some attempt is made to describe or define this source in terms different from that of pure consciousness, then I don't see how it differs from idealism.

In relation to Polkinghorne, I would merely add that scientists are dealing with the apparent facticity of matter.
