This is by no means a comprehensive bibliography, but we thought that our readers would be interested in the following studies of Wittgenstein and ethics published within the last ten years. We will be adding gradually to this list over time, and if you know of other works on this subject please leave us a note in the comments.
Eric B. Litwack, Wittgenstein and Value: The Quest for Meaning (2009)
J. Jeremy Wisnewski, Wittgenstein and Ethical Inquiry: A Defense of Ethics as Clarification (2007)
Wittgenstein and the Moral Life: Essays in Honor of Cora Diamond (2007) — Contributors: Stanley Cavell, James Conant, Alice Crary, David Finkelstein, Juliet Floyd, Michael Kremer, Sabina Lovibond, John McDowell, Stephen Mulhall, Martha Nussbaum, and Hilary Putnam
Bob Plant, Wittgenstein and Levinas: Ethical and Religious Thought (2005)
Duncan Richter, Wittgenstein at His Words (2004) — see Chapter 4, “Ethics”
Marx and Wittgenstein: Knowledge, Morality and Politics (2002), ed. Gavin Kitching and Nigel Plesants
Paul Johnston, The Contradictions of Modern Moral Philosophy: Ethics after Wittgenstein (1999)
Johnston’s earlier studies, Wittgenstein and Moral Philosophy (1989) and Wittgenstein: Rethinking the Inner (1993) may also be of interest to readers. For those who are new to the subject, Sabina Lovibond’s Realism and Imagination in Ethics (1983) remains one of the best earlier studies on the relevance of Wittgenstein’s philosophy to ethical thought.
