Maurice Lagueux's new book, winner of the Governor General's Award, is a collection of essays on different topics in Marxist philosophy and social thought. Often very critical of the ideas and theses he examines, the unifying theme of the collection is indicated by the subtitle, “une saison dans l'histoire de la pensée critique”. Lagueux's efforts are largely devoted to evaluating the ideas that captured the imagination of much of the left, especially in Quebec, during the sixties, “une saison où la gauche avait le vent dans les voiles”.
