A flaw in Freud's Interpretation of Dreams prompts reevaluation of his view of the work as his seminal achievement.

Freud always regarded The Interpretation of Dreams, and in particular its thesis that dreams fulfill wishes, as his landmark contribution and the scaffolding of his subsequent work. Susan Sugarman, after carefully examining the text and scrutinizing a range of Freud's other works, shows that the dreams book is not and cannot be that scaffolding. For, not only does his argument on dreams falter, but his reasoning elsewhere – in his case histories, his accounts of phenomena of ordinary waking life, and even his avowedly speculative writing – displays a strength and precision his account of dreams lacks. She concludes by exploring what is then left of the dreams theory and Freud's overall vision of the mind.
