The section on Seminar 20 is an attempt to extract three critical concepts from Lacan’s Seminar 20, a seminar that is well known in the Anglophone world due to its early translation and that is a critical seminar at the point of transition of Lacan into the final phase of his work and delineation of his separation or disjunction from aspects of Freud’s work. I might also add that it is indeed the work of the later Lacan, say from Seminar 20 forward, that has, in some ways, the most relevance to my particular claim for the place for Lacan in addressing the psyche of the twenty-first century, as will be developed in several chapters.
