This is the first handbook focussing on classical social theory. It offers extensive discussions of debates, arguments, and discussions in classical theory and how they have informed contemporary sociological theory. The book pushes against the conventional classical theory pedagogy, which often focused on single theorists and their contributions, and looks at isolating themes capturing the essence of the interest of classical theorists that seem to have relevance to modern research questions and theoretical traditions. This book presents new approaches to thinking about theory in relationship to sociological methods.
