Double-aspect theory

Double-aspect theory is a philosophical concept primarily associated with the philosophy of mind and metaphysics. It posits that mental states and physical states are two aspects of a single underlying reality. Unlike dualism, which asserts that mental and physical substances are fundamentally different, or materialism, which reduces all phenomena to physical processes, double-aspect theory proposes that both mental and physical phenomena arise from the same foundational substance or reality, but they are perceived or experienced in different ways.
