Is there some other way to resolve the duplication problem that acknowledges this insight? Remember that according to Parfit, we all agree that if my brain is transplanted into someone else’s brainless body, and the resulting person has my character and apparent memories, then this resulting person is me. But should we agree, or do these intuitions rest on questionable assumptions?
What does it take for you to persist across time? What sorts of changes could you survive, and what sorts of changes would bring your existence to an end? The dominant approach to personal identity says that a person persists over time by virtue of facts about psychological continuity (e.g. continuity of memory, character, or mental capacities). Various puzzle cases have been presented to support this view.
For many years, the prevailing view among both cognitive scientists and philosophers has been that the brain is sufficient for cognition, and that once we discover its secrets, we will be able to unravel the mysteries of the mind. Recently however, a growing number of thinkers have begun to challenge this prevailing view that mentality is a purely neural phenomenon.
