The analysand must tell his truth; this is the fundamental rule. For the one who hears the saying through lapses and free associations, experiences it as demanding an interpretation–which is not addressed to the subject of intentionality but to the subject who is continuously dividing. Psychoanalytic listening is a reading of signifiers. It results from the transference at work during treatment. This knowledge production imposes itself as much on the analyst as on the analysand. Listening is a theoretical experience where the master signifier induces the analysand’s neurotic orientation and incestuous phantasy. Such a psychotherapeutic ideology testifies to the disappearance of psychoanalysis as a specific experience that implies a theoretical elaboration on truth production emerging from unconscious knowledge. In psychoanalysis, the theoretical experience of listening–the use of formal concepts–is indeed a conceptual step. Psychoanalytic science is characterised by determinism of unconscious components which is overtaken by causal structuring of the object of the drive.
