Hello Jon, not sure if you have read much of Bernardo Kastrup, but your explanation of minds and mini-mind seems quite similar to me to his idea. You may have noticed that I have been trying to work through the questions of idealism and realism, with Kastrup being more or less on one far end of the idealism spectrum. I am far closer to the mind idea than I used to be although I always thought of mind first, and matter proceeding from it. Now it is getting harder and harder to distinguish what is mind and what is matter — even when looking at it from a physicist perspective! Interesting times!
