What is dualism in physicalism?

Physicalism is a form of ontological monism—a “one substance” view of the nature of reality as opposed to a “two-substance” (dualism) or “many-substance” (pluralism) view. Both the definition of “physical” and the meaning of physicalism have been debated. Physicalism is closely related to materialism.
