Jeffrey Masson's version of the seduction theory episode in Freud's early career, as presented in The Assault on Truth, is very plaus ible as a revised account of the traditional story. However, close examination of the seduction theory papers and of other contemporary documents reveals that Freud's later reports of the episode, the foun dation on which Masson builds his case, are false. Some purported his torical events that Masson uses to buttress his case are also shown to be without (...) foundation. The several accounts of the episode Freud gave in his writings are dissected to demonstrate that they are tendentiously misleading and serve to conceal what actually occurred with his patients during the period in question. Some consequences of the widespread acceptance of the traditional account are briefly discussed. (shrink)
