The subjects of Philosophy, Political Science, and Economics are naturally complementary.

There are many questions, both practical and theoretical, to which these disciplines contribute differing yet complementary perspectives. The question of what policies we ought to adopt to address climate change, for example, has economic, political, and philosophical dimensions. Other topics of common interest to these disciplines include: immigration, global justice, taxation, inequality and redistribution, population ethics, markets and democracy, repugnance and the limits of markets, the future of work, voting theory and social choice, freedom of choice, human rights, theories of well-being, and the nature and limits of rationality, among many others.
