What is "lacanianism"

Lacanianism is the study of, and development of, the ideas and theories of the dissident French psychoanalyst Jacques Lacan. Beginning as a commentary on the writings of Freud, Lacanianism developed into a new psychoanalytic theory of humankind, and spawned a world-wide movement of its own.

Fredric Jameson has argued that "Lacan's work must be read as presupposing the entire content of classical Freudianism, otherwise it would simply be another philosophy or intellectual system".
