Murphy, "Human Nature," 24-25. Murphy’s term, ‘holistic dualism’, is roughly equivalent to Barbour’s ‘dual-aspect monism’, since she means by it "the person is a composite of separable ‘parts’ but is to be identified with the whole...functioning as a unity". On nonreductive physicalism see also Murphy, "Supervenience," esp. Sec. 3; Murphy, Beyond liberalism and fundamentalism, esp. Ch. 6.
