PASSAGE
A person, Sam, is teleported to Mars. The machine scans and destroys Sam's body on Earth. However, the transmission is intercepted and used to create two perfect replicas: Sam-A on Mars and Sam-B on Venus. Sam-A and Sam-B have identical memories and psychological states up to the moment of teleportation.
The creation of two replicas from one original primarily demonstrates that psychological continuity (Relation R, in Parfit's terms) lacks a logical property required for identity. What is that property?
