Dual-aspect monism is the view that the mental and the physical are two different aspects of the same underlying reality. Instead of seeing mind and matter as completely separate substances (as in Cartesian dualism) or reducing one entirely to the other (as in strict physicalism), this perspective suggests both are complementary expressions of a single, unified entity. It invites us to consider that what we observe as “physical” and what we experience as “mental” are two sides of the same coin, each offering unique insights into the nature of existence.
