Talk:Seminar XXIII

Lacan introduces the term in 1975, as the title for the 1975-6 seminar, which is both a continuing elaboration of his topology, extending the previous seminar's focus on the borromean knot, and an exploration of the writings of James Joyce.

Through this coincidentia oppositorum -- bringing together mathematical theory and the intricate weave of the Joycean text -- Lacan redefines the psychoanalytic symptom in terms of his final topology of the subject.
