"Michael Walzer has written about a wide variety of topics in political theory and moral philosophy: political obligation, just and unjust war, nationalism and ethnicity, economic justice and the welfare state. He has played a part in the revival of a practical, issue focused ethics and in the development of a pluralist approach to political and moral life. He is currently working on the toleration and accommodation of "difference" in all its forms and also on a (collaborative) project focused on the history of Jewish political thought."
