Since the foundational essays of Max Horkheimer nearly 100 years ago, the term "social philosophy" carries connotations that suggest more than just the examination of a philosophical subject alongside others; it implies a specific, critical approach to its object: contemporary society. In this collection of programmatic texts, Martin Saar explores the application, the gesture, the methods, and the fundamental concepts of such a socially critical reflection. He outlines the profile of a still potent, diagnostically motivated form of thinking that engages closely with the actual struggles and realities of our political and social world.
