Abstract

The development of a metaphysics of actuality is reconstructed from Plato through Bergson to capitalize on Bergson's suggestion that mind and matter can be understood as inversions of each other, or as respectively a centering and an extending of forms. This view avoids the pitfalls of reductive monism and disjunctive dualism: it is dyadic (cognizant at once of mind-matter difference and of the unity of reality), symmetrical (not apt to close off prematurely our reckoning with complexity and change, on either side), and correlational (able to track relations of form, energy, and sequence between mental and material items).
