Teletransportation paradox
The Teletransportation paradox or teletransport paradox (also known in alternative forms as the duplicates paradox) is a thought experiment on the philosophy of identity that challenges common intuitions on the nature of self and consciousness, formulated by Derek Parfit in his 1984 book Reasons and Persons. If a person is somehow re-created, say by teletransportation, is the re-creation the same person?
