 Despite the rise to prominence of the register of the Real beginning around 1959–1960, the Symbolic continues to play pivotal roles in Lacan’s teachings right up until the start of the 1980s. For instance, in Seminar XVII (1969–1970) and the contemporaneous interview “Radiophonie,” Lacan forges his theory of the “four discourses” (those of the “master”, “university,” “hysteric,” and “analyst”) to reflect the interlinked permutations of multiple kinds of “social links” configuring the relations between speaking subjects. More generally, the later Lacan remains reliant on the notion of the Real sides of the Symbolic, these being signifiers in their meaningless, nonsensical materiality as visible marks and audible sounds (i.e., “letters” in Lacan’s technical sense)—and this by contrast with the Imaginary sides of the Symbolic, in which signifiers are paired with signifieds to form meaningful, significant signs (à la Saussure’s classic explanation of successful communication via natural language). Such senseless signifiers and their enchainings amount to a late Lacanian rendition of Freudian primary processes as the thinking distinctive of unconscious mindedness.
