Masson, who has the virtue of at least being honest in his views, has been refuted so many time by so many scholars from different circles, that I find it strange that some still think his thesis revolutionary. Ignorance of relevant literature certainly makes one vulnerable to Masson's own assault on truth. For a brief yet exhaustive account of the history Masson mentions the reader may consult G. Izenberg's essay in The Combridge Companion to Freud. Another helpful book--which exposed Masson so much that he sued its author, and lost--is In the Freud Archives by Janet Malcom.
