(For earlier versions of this Note, see the table at the end)


MPD - otherwise known as Dissociative Identity Disorder (DID). This condition is normally viewed as psychopathological1, to be treated by therapy. It occurs where a human being is, or appears to be, “home” to more than one person2, or at least more than one personality3. These persons/personalities may be radically dissimilar, and are (as the alternative designation implies) dissociated from one another. They can be like Locke’s night and day man “incommunicable consciousnesses”, unaware of one another’s existence – hence being in Lockean terms different persons; or, they can be aware of one another, but as of distinct persons.

No doubt one could complain that the clinically-recorded cases are exaggerated, fabrications or otherwise unreliable. But there seems nothing wrong with them as TEs4, and ones least open to cavil given their approximation to reality.

Effectively, we have a brain running more than one mind-program (on the “mind-as-software” approach); or a brain segregated into more than virtual machine (on the “mind as hardware”) approach to the mind-brain relationship.

MPDs pose no problems to those espousing the Psychological View (PV5) – other than ethical issues concerning “therapeutic” suppression or unification of the alleged multiple persons (see "Shoemaker (David) - Moral Issues at the End of Life"), but what is the response of or the Constitution View (CV6)? Can we have more than one person – with more than one First Person Perspective (FPP7) – constituted by the same human body? Animalism8 ignores psychological factors altogether as far as identity is concerned, so won’t be troubled.

This is mostly a place-holder9. Currently, just see the categorised reading-list (if any).
