Many students of the arts and humanities probably first encounter the name of Jacques Lacan in one of the numerous studies of the French Structuralist movement, an intellectual paradigm which attained the zenith of its public success during the 1960s, and which has since occupied many an Anglo- American scholar's critical spotlight, either as a fashionable esoteric creed or as an original explanatory doctrine. Invariably associated with the contributions of Claude Lévi-Strauss, Roland Barthes, Michel Foucault, and Louis Althusser – the central quadrivium of Structuralism – Lacan's oeuvre has indeed frequently appeared as another influential instance of how Structuralist ideas managed to change the face of many research areas in the human and social sciences, in his case the field of Freudian psychoanalytic practice. Whereas his companions have been hailed or vilified for their Structuralist approaches to anthropology, literary criticism, philosophy, and politics, Lacan has entered history as the quintessential defender of the Structuralist cause in psychoanalysis, an acolyte so militant that he did not shrink from making the claim that Freud himself had always been an inveterate structuralist avant la lettre.

The main reason for Lacan’s recognition, and his intermittent selfidentification as a Structuralist is situated in his allegiance to the basic principles of Structuralist linguistics, as inaugurated by Ferdinand de Saussure in his famous Course in General Linguistics, published posthumously in 1916, and as elaborated from the late 1920s by Roman Jakobson, founding member and chief representative of the Prague Linguistic Circle.
