Jacques Lacan's contribution on debate about chilhood psychosis in 1953

There is a teaching by J. Lacan on childhood psychosis which begins from its first seminary in 1953. J. Lacan comments at first on Dick's case, which is presented by M. Klein in 1930, then Robert's case, presented in its seminary by one of his learners, Rosine Lefort. Assuming the comment of Freud's text "Die Verneinung" by J. Hyppolite, and its consequences about difference between symbolisation in general and Bejahung in particular, J. Lacan show what will becoming the very structure of psychosis, that is to say the gap of a fundamental significant, which is, here, the "ideal du moi". (c) 2007 Elsevier Masson SAS.
