Now a Major Motion Picture by legendary director David Cronenberg starring Viggo Mortensen, Kiera Knightley and Michael Fassbender.In 1907, Sigmund Freud and Carl Gustav Jung began what promised to be both a momentous collaboration and the deepest friendship of each man's life. Six years later they were bitter antagonists, locked in a savage struggle. In between them stood a young woman named Sabina Spielrein: a patient and lover to Jung, a colleague and confidante to Freud, and one of the greatest minds in modern psychiatry.This mesmerizing book reconstructs the fatal triangle of Freud, Jung and Spielrein. It encompasses clinical methods and politics, hysteria and anti-Semitism, sexual duplicity and intellectual brilliance wielded as blackmail. Learned, humane and impossible to put down, A Dangerous Method is intellectual history with the narrative power and emotional impact of great tragedy.
