Book excerpt: A Philosophical History of German Sociology presents a systematic reconstruction of critical theory, from the founding fathers of sociology (Marx, Simmel, Weber) via Lukács to the Frankfurt School (Horkheimer, Adorno, Habermas). Through an in depth analysis of the theories of alienation, rationalisation and reification, it investigates the metatheoretical presuppositions of a critical theory of the present that not only highlights the reality of domination, but is also able to highlight the possibilities of emancipation. Although not written as a textbook, its clear and cogent introduction to some of the main theories of sociology make this book a valuable resource for undergraduates and postgraduates alike. The following in-depth investigation of theories of alienation and reification offer essential material for any critique of the dehumanizing tendencies of today’s global world. Recently translated into English from the original French for the first time, this text showcases Vandenberghe's mastery of the German, French and English schools of sociology study. The result is an important and challenging text that is essential reading for sociology students of all levels. Frédéric Vandenberghe is a Sociology professor and researcher at Iuperj (Instituto Universitário de Pesquisas do Rio de Janeiro), Rio de Janeiro, Brazil. His writings on a broad range of sociological topics have been published as books and articles around the world.
