You can say "dualism" if you want, but I still object to your conflating it with postmodernistic subjective reality, as you did in the other thread:
Even if you call it "dualism," it is still not dual in the sense that postmodernism is plural. It posits a single, objective reality, of which the physical universe is a part. Changes to or violations of the rules of the physical universe are because it is part of a larger system, and is changing as a result of consistent rules operating in that system.
Postmodernism, on the other hand, posits multiple realities which are subjective and arbitrary. Changes to reality are because you've managed to dream up something different.
