Philosophy, Politics, and Economics (PPE) were integrated until the late 19th century, when they became distinct academic disciplines. This separation advanced the goals of specialized academic research, but students are often better served by examining the connections and tensions among the three disciplines.

The revival of PPE began at Oxford University in 1920, and has now spread to over 100 institutions worldwide. Important issues ranging from health care allocation and global pandemics to nuclear weapons proliferation and climate change have moral, political, and economic dimensions.  Economics and Political Science can help us understand these issues; Philosophy can help us evaluate different proposed solutions to them.  PPE students learn to look at the world through different windows, and to think about the relative role of markets and political institutions in promoting human welfare.
