Double-Aspect Theory
Double-Aspect Theory
Theory that the mind and the body of an individual are two distinguishable but inseparable aspects of a single underlying substance or process. Spinoza, as a consequence of his metaphysical doctrine trnt “thinking substance and extended substance are one and the same thing” (Ethics, Part II, prop. 7) was committed to the Two-Aspect Theory of the body-mind relation. Cf. C. Lloyd Morgan (Life, Mind and Spirit, p. 46); S. Alexander (Space, Time and Deity) and C. H. Strong are recent advocates of a two-aspect Theory. — L.W.
