Book excerpt: According to Russellian monism, an alternative to the familiar theories in the philosophy of mind that combines attractive components of physicalism and dualism, matter has intrinsic properties that both constitute consciousness and serve as categorical bases for the dispositional properties described in physics. Consciousness in the Physical World collects various works on Russellian monism, including historical selections, recent classics, and new pieces. Most chapters are sympathetic with the view, but some are skeptical. Together, they constitute the first book-length treatment of the view itself, its relationship to other theories, its motivations, and its problems.
