Mind transfer

In transhumanism and science fiction, mind transfer (also referred to as mind uploading or mind downloading, depending on one's point of reference), or whole body emulation refers to the hypothetical transfer of a human mind, body, and environment to an artificial substrate.

Copying vs. moving

By some definitions, the copied consciousness would 'be the same person' as the donor of the consciousness. In that case, this new being -- the same person as the original -- could have all the rights of the consciousness donor, including the disposal of the old body. By other definitions, the two copies would immediately be considered different people and the issue of which copy 'inherits' what can be much more complicated. This problem is similar to that found when considering the possibility of teleportation, where in some proposed methods it is possible to copy (rather than only move) a mind. This is the classic philosophical issue of personal identity.

Philosopher John Locke published "An Essay Concerning Human Understanding" in 1689, in which he proposed the following criterion for personal identity: if you remember thinking something in the past, then you are the same person as he or she who did the thinking. Later philosophers raised various logical snarls, most of them caused by applying Boolean logic, which was the only logic available at the time. It has been proposed that modern fuzzy logic can solve those problems, showing that Locke's basic idea is sound if one treats personal identity as a continuous rather than discrete value.

In that case, when a mind is copied -- whether during mind uploading, or afterwards, or by some other means -- the two copies are initially two instances of the very same person, but over time, they will gradually become different people to an increasing degree.
