Inevitably the disconnection leads to ravings and mania like the international economic system, where pure algorithms of value disconnect from reality so completely that they're in serious danger of destroying themselves.

This passage helped me finally to understand (I think) the root of Gaianne's concern about our metaphysics and its adequacy (or lack thereof) to equip us for dealing with social and environmental crises.

But maybe I missed this earlier because, agreeing with you that

the Western Mind ... shrinks back in horror from mysticism and explicit dualism,

I do not believe that the Western mindset can be equated with "rational dualism" (which indeed is not adequate for dealing with the results of modern science and logic, nor with the real world crises we face).

I would go further that if

it [the Western Mind] still works on the assumption that Mind is separate from Reality, and that the only way to understand Reality is by making Mind (i.e. abstracted pattern recognition) and Reality as separate as possible

then even this is a modern manifestation of a Platonist, Manichean hold-over that has persisted in our culture in various forms (with some tragic consequences), but is divergent from a more fundamental Western "metaphysics" that construes reality as both spiritual and material (in a complementary, non-contradictory relationship), and that understanding comes from both personal reflection and contemplation as well as from experience and participation within the material world and within society among other people.

Truth unfolds in time through a communal process.
