This course aims to introduce graduate and professional students from a wide range of backgrounds outside of philosophy to some central moral questions about social structures and institutions. Discussion will center on concerns of justice, broadly construed as the basic virtue of social institutions, and including topics such as economic inequality, freedom, class, race, gender and environmental injustice. In particular, the course will ask what it is to treat people as equals, and consider different answers to this question proposed by (for example) utilitarians, liberals, libertarians, communitarians, Marxists and nationalists. Students will consider conceptual frameworks for thinking about familiar difficulties that arise in attempts to fashion fair and decent policies in various areas of our lives. They will also consider applications to different areas, including their own field of study.
