Four discourses is a concept developed by French psychoanalyst Jacques Lacan. He argued that there were four fundamental types of discourse. He defined four discourses, which he called Master, University, Hysteric and Analyst, and suggested that these relate dynamically to one another.
Lacan's theory of the four discourses was initially developed in 1969, perhaps in response to the events of social unrest during May 1968 in France, but also through his discovery of what he believed were deficiencies in the orthodox reading of the Oedipus Complex. The Four Discourses theory is presented in his seminar L'envers de la psychanalyse and in Radiophonie, where he starts using "discourse" as a social bond founded in intersubjectivity. He uses the term discourse to stress the transindividual nature of language: speech always implies another subject.
Prior to the development of the Four Discourses, the primary guideline for clinical psychoanalysis was the Oedipus Complex. In Lacan's Seminar of 1969-70, he argues that there was a major problem with the Oedipus complex, namely that the father is already castrated at the point of intervention, rendering the orthodox Freudian reading, where the father becomes a terrifying figure, a neurotic fantasy. Lacan's solution to the tendency of analysts to invoke their own imaginary readings and neurotic fantasies was to begin to formalise psychoanalytic theory, and express it in mathematical functions. This would ensure not only that a minimum of the teaching is lost when communicated, but also limit the associations of the analyst with the concepts employed.
Discourse, in the first place, refers to a point where speech and language intersect. The four discourses represent the four possible formulations of the symbolic network which social bonds can take and can be expressed as the permutations of a four-term configuration showing the relative positions — the agent, the other, the product and the truth — of four terms, the subject, the master signifier, knowledge and objet petit a.
The four positions in each discourse are :
