 Unsurprisingly, the Second World War was, for Lacan (and, of course, for history generally), a period of disruption and upheaval. His psychoanalytic activities were interrupted, including his training analysis (Lowenstein and Lacan did not concur about whether this analysis was well and truly completed, with Lacan deciding it was over and, somewhat controversially, never returning to Lowenstein’s couch). The War provided Lacan with an exposure to military psychiatry in both France and England, with his five-week visit to the latter acquainting him with aspects of the British psychoanalytic world (features of this visit are recounted in “British Psychiatry and the War” [1947]). A handful of important texts were composed during and after the War, all of which eventually got reprinted in Lacan’s magnum opus, Écrits (1966): “Logical Time and the Assertion of Anticipated Certainty: A New Sophism” (1945); “Presentation on Psychical Causality” (1946); “Aggressiveness in Psychoanalysis” (1948); and “The Mirror Stage as Formative of the I Function as Revealed in Psychoanalytic Experience” (delivered in 1949 at the IPA conference in Zurich—whereas the 1936 version from Marienbad is lost, this version is the surviving one made canonical through its inclusion in Écrits).
