|Identity: Two objects are never identical. Identity is a single object, to which may be referred to with two different terms. The fact that two descriptions mean a single object may be discovered only in the course of an investigation.|

Identity/object/thing/semantics of possible worlds/Kripke/Hintikka: Kripke thesis: the existence of permanent (endurant) objects must be assumed as a basic concept.
HintikkaVsKripke: this requirement is not well-founded. Perhaps one must, however, presuppose the criteria of identification and of identity only for traditional logic and logical semantics. But that does not mean that the problem of identification is not a permanent problem for philosophers.
Knowing-who/Identity/Psychology/Psychiatry/Hintikka: there are interesting examples here. One must be able to recognize oneself as the same in different situations.
