Ruth Groff teaches courses in political theory and philosophy. Her interests are in the history of Western social, political, and moral thought, and in questions about explanation, truth, and causality. She has a hard time picking favorites, but she will say that she very much enjoys the works of Plato, Aristotle, Marx and Mill. Her book Critical Realism: Post-Positivism and the Possibility of Knowledge was published in 2004 by Routledge, and her Revitalizing Causality, a collection of articles on realism about causality, is forthcoming from Routledge. She is currently working on the metaphysical assumptions that shape the ways that we think about freedom.
