From de Clérambault's Theory of Mental Automatism to Lacan's Theory of the Psychotic Structure

In 1966, in a paper on those who have influenced his work, Jacques Lacan suggested that his concept of ‘paranoid knowledge’ and his structural approach to psychoanalysis were closely linked to the work of Gaëtan Gatian de Clérambault. This article examines both of these points. Starting with an introduction to de Clérambault, focusing on his concept ‘mental automatism,’ the link between ‘mental automatism’ and ‘paranoid knowledge’ is discussed. Loyalty to Henri Claude and conflicts around theoretical and clinical issues seem to lie at the basis of Lacan's initial neglect of his conceptual indebtedness to de Clérambault. Second, the author discusses the presumed connection between mental automatism and Lacan's structural psychoanalytic theory, which Lacan did not elaborate. It is argued that from a structural perspective, mental automatism comes down to a rupture in the continuity of the signifying chain, which provokes the disappearance of the subject. Furthermore, Lacan's theory implies the hypothesis that manifestations of mental automatism are determined by a foreclosure of the Name-of-the-Father, where questions related to existence cannot be addressed in a stable way. Lacanian theory thus retained de Clérambault's notion of a rupture in mental life that lies at the basis of psychosis, but replaced his biological framework with the dimension of the subject as produced through speech.
