Our world is divided into many different states, each of which has its own culture or set of cultures. Vast inequalities of wealth and power exist between citizens of the rich world and the global poor. International commerce, immigration, and climate change entwine our lives in ways that transcend borders. It is in this context that problems of global justice, which relate to the normative obligations that arise from our international order, emerge. What demands (if any) does justice impose on institutions and individuals acting in a global context? Is it morally permissible to prioritize the welfare of our compatriots over the welfare of foreigners? Do states have the right to control their borders? What are the responsibilities (if any) of wealthy states, consumers, and multinational corporations to the global poor? This course explores longstanding problems of global justice via a discussion of contemporary issues: global poverty, global public health, immigration, human rights and humanitarian intervention, self-determination, and climate change. There are no easy answers to these questions, and the complexity of these issues requires an interdisciplinary approach. While there are several possible theoretical approaches to problems of global justice, the approach taken in this course will be rooted in political philosophy and political theory. We will combine readings from political philosophy and theory with empirical material from the social sciences, newspaper articles, and popular media. By the end of this course, students will be familiar with contemporary problems of global justice, be able to critically assess theoretical approaches to these problems, and be able to formulate and defend their own views on these complex issues.
