“ In philosophy it denotes in its broadest sense the theory (e.g. of the Pythagoreans) that the human soul does not die with the body but is " born again " in new incarnations. It is thus the equivalent of metempsychosis (q.v.) . The term has a narrower and more specific use in the system of Schopenhauer, who applies it to his doctrine that the will does not die but manifests itself afresh in new individuals. ”
