An excellent presentation of Chisholm’s views on these matters can be found in [P&amp;O], as well as in his papers “Is There a Mind-Body Problem?” (1978) and “On the Simplicity of the Soul” (1991). Chapters 4, 6, 7, and 13 of [OM] are especially helpful. For a brief final discussion of the metaphysics of persons, see “Persons and Their Bodies: Some Unanswered Questions” (1996).
