Summary of Parfit, Reductionist Perspective, and Ethical Commitment: Between reasons and people, Derek Parfit insists on a simplified theory of individual identity. According to reducingists, people do not transcend the existence of certain psychological and / or physical conditions and their various relationships. With this in mind, Parfit believes that the identity of an individual includes only this more concrete fact about psychological continuity and / or relevance, so that the identity of the individual may be based on this continuity and / I think that it can be simplified to.
Derek Parfit explained and explained the difference between non-minimalist and minimalist's personal identity in Parfit in 1984 (he initially put it in "simple" view and "complex" view of Parfit 1973 I divided). For the first statement of the psychological criteria of identity, see "Consistency Persistence" in 1979 by John Locke of Locke and Nedditch. For non-inductive objections, see Thomas Reid's Prose for Man and Butler's Knowledge 1736. Advocacy for Contemporary Psychology, Harold-Noonan's Identity, and 1984 Sydney Schubert's Shoe Maker's Contribution For non-reductionism of modern identity, see Swinburne's contribution. For the modern support of biological standards, see Olson 1997.
Derek Parfit was one of the first contemporary theorists who explicitly explored the relationship between identity and morality from the "personal identity" that began in the early 1970s, in particular "the principle of self-and late morals". That is his remark and prospect of development. The third part of his book, Reasons and People (published in 1984), then the paper was obtained. In many respects, Parfit is a description of Rockman's personal identity despite major deviations. He is a "reductionist" and the facts about human and individual identity include more specific facts about the brain, the body, a series of interrelated psychological and physical events (Parfit 1984, 210-211). Negative reductionism is called "non-return principle". According to this doctrine, facts about human and individual identity usually include facts about Descartes' self or spirit.
