I am a Professor in the Philosophy Department at Cornell University and Director of the Program on Ethics and Public Life. My main interest is social and political philosophy. My writing and teaching on international justice concern such topics as duties to help the global poor, the moral status of patriotism and of special duties toward compatriots, moral problems of globalization and global climate change, the ethics of war, and the moral implications of American power. My emphasis is on how transnational relationships of power shape political responsibilities, the theme of my book, Globalizing Justice: The Ethics of Poverty and Power (2010). My writing and teaching on social justice within the nation-state often concern the moral significance of economic inequality, the nature and implications of democratic values and the proper political role of evaluations of ways of life. Some topics of my current work are the role of mutual concern in the foundations of economic justice, the importance of equality of political influence and its implications for political and economic reform, moral issues posed by the U.S. response to the rise of China, the assessment of Rawls’ account of economic justice, domestic and international, and the relationship between intended and foreseeable harm in judgments of moral permissibility. 1971-1973: Instructor, Department of Philosophy, Massachusetts Institute of Technology 1973-1979: Assistant Professor of Philosophy, Cornell University 1976, Winter and Spring quarters: Visiting Assistant Professor of Philosophy, University of California at Los Angeles 1979-1986: Associate Professor of Philosophy, Cornell University 1986-date: Professor of Philosophy, Cornell University 2011-date: Wyn and William Y.
