There is an urgent need to elaborate a theory of affects for Lacanian psychoanalysis. This is Colette Soler’s intention in her book Lacanian Affects: The Function of Affect in Lacan’s Work (2015). Soler announces that she will provide a systematic overview of Lacan’s copious yet misunderstood theses on affects. Indeed, her book engages with affects like “anguish” (Fink has decided to choose this term to render the French word of angoisse, instead of the more common “anxiety”) but also sadness, joy, guilt, boredom, moroseness, anger, shame, love, hatred, enthusiasm, and so on. Soler rightly points out Lacan’s Freudian point of departure and highlights his distinctive contribution, even though she acknowledges that his concept of affect was fraught with tensions, false starts, or even contradictions. Lacan, as usual, offers brilliant insights couched in impenetrable and punning prose. When closing Soler’s book, though, one cannot help registering a certain degree of frustration: the original promise of presenting a clear and systematic Lacanian theory of affects has not been fulfilled; too often, the book remains mimetic in tone and style and not explanatory enough.
