In 1969, Lacan moved his public seminars to the Faculté de Droit (Panthéon), where he continued to deliver his expositions of analytic theory and practice until the dissolution of his school in 1980.
The Overture to the Caracas Encounter was to be Lacan's final public address. His last texts from the spring of 1981 are brief institutional documents pertaining to the newly formed Freudian Field Institute.
Lacan thought that Freud's ideas of "slips of the tongue", jokes, and the interpretation of dreams all emphasized the agency of language in subjects' own constitution of themselves. In "," he proposes that "the unconscious is structured like a language." The unconscious is not a primitive or archetypal part of the mind separate from the conscious, linguistic ego, he explained, but rather a formation as complex and structurally sophisticated as consciousness itself. One consequence of his idea that the unconscious is structured like a language is that the self is denied any point of reference to which to be "restored" following trauma or a crisis of identity.
In The Four Fundamental Concepts of Psychoanalysis Lacan argues that "man's desire is the desire of the Other." This entails the following:
Lacan identifies four partial drives: the oral drive (the erogenous zones are the lips (the partial object the breast—the verb is "to suck"), the anal drive (the anus and the faeces, "to shit"), the scopic drive (the eyes and the gaze, "to see") and the invocatory drive (the ears and the voice, "to hear"). The first two drives relate to demand and the last two to desire.
Lacan's writings from the late sixties and seventies (thus subsequent to the 1966 collection) were collected posthumously, along with some early texts from the nineteen thirties, in the Éditions du Seuil volume Autres écrits (2001).
