Freud is in these pages for what the artists took from him rather than for the clinical work itself. The Interpretation of Dreams (1899) supplied the twentieth-century avant-garde with a usable proposition: that the mind edits itself, that the edit can be got around, and that what surfaces when it is has meaning. Surrealism built a method on that, and André Breton — who had used psychoanalytic technique on shell-shocked soldiers during the war — wrote it into the 1924 manifesto.
Freud himself was unimpressed. He thought the Surrealists cranks, and said so, until Salvador Dalí was brought to his house in London on 19 July 1938 with a painting under his arm. Freud had fled Vienna three months earlier and had a year to live. He wrote to Stefan Zweig the following day that the young Spaniard's technical mastery had made him reconsider.
