Freud and Lacan

Louis Althusser offered this helpful description of Lacan’s structuralist revision of Freud: “In his first great work The Interpretation of Dreams . . . , Freud studied the ‘mechanisms’ and ‘laws’ of dreams, reducing their variants to two: displacement and condensation. Lacan recognized these as two essential figures of speech, called in linguistics [respectively] metonymy and metaphor. Hence slips, failures, jokes and symptoms, like the elements of dreams themselves, become signifiers, inscribed in the chain of an unconscious discourse, doubling silently, i.e. deafeningly, in the misrecognition of ‘repression,’ the chain of the human subject’s verbal discourse . . . . Hence the most important acquisitions of de Saussure and of the linguistics that descends from him began to play a justified part in the understanding of the process of the unconscious as well as that of the verbal discourse of the subject and of their inter-relationship, i.e. of their identical relation and non-relation in other words, of their reduplication and dislocation ( décalage ).”
