Although "Three Essays on the Theory of Sexuality" is considered a foundational text for psychoanalysis, it remains, to some extent, "unknown." In this book, presented by the Belgian philosopher and psychoanalyst Philippe Van Haute and the Dutch philosopher Herman Westerink, Sigmund Freud's 1905 theory of sexuality is reconstructed within its historical context, systematic framework, and contemporary relevance. This reconstruction reveals a non-Oedipal theory of sexuality defined as autoerotic, non-object-based, with pleasure activities driven by the drive and excitability of erogenous zones. Thus, this book explores the inconsistencies and problems arising from Freud's theory of sexuality, notably the theoretical and methodological changes between the first edition of the original text and its subsequent editions. This book is of great interest to psychoanalysts and scholars interested in the history of psychoanalysis and sexuality.
