|Private language: according to L. Wittgenstein a private language, i.e. a language which an individual develops only for himself and uses to express his feelings, is not possible. (See L. Wittgenstein, Philosophical Investigations, 1953, § 243, 258). You cannot give yourself instructions. You could not even understand the language. See also rule following, Kripke's Wittgenstein, priviledged access, Wittgenstein's beetle._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
