In this paper Lacan's theory is used to clarify the success of a number of techniques and interventions with schizophrenics, proposed by therapists at the Michigan State University Psychotherapy Project. The author first points to a deficit in Lacan's theory which is described by means of arguments presented by Corveleyn (1998) and Vergote (1998). In comparing Lacan's theory and a successful American practice, the author focuses on a publication by Karon and VandenBos (1981), one of the most important to issue from the Michigan State University Psychotherapy Project.1 Both Karon's general advice and practical techniques are utilized and the question is asked as to whether Lacanian theory as corrected by the suggestions of Corveleyn and Vergote can explain the success of Karon's approach.
