This book, written in Spanish, focuses on the literary and artistic works of such avant-garde figures as Ramón Gómez de la Serna, Benjamín Jarnés, Antonio de Obregón, Juan Chabás, Rosa Chacel, Claudio de la Torre, Almada Negreiros, Maruja Mallo, Mauricio Amster, Manuel Reinoso, Diego Rivera, and Ángeles Santos y Victorio Macho. It identifies the attempt to integrate conflicting epistemological, ethical, and sociopolitical categories as the organizational principle driving the avant-garde novel and art. Seen as a means of escaping the Cartesian dualism of mind and matter, the conflict between ethical institutionism and utilitarianism, and the opposition of liberalism by socialism, this "middle path" manifests itself in the avant-garde on various levels: the theory of representation, the development of the protagonist, and the concept of history.
