Penn has special strengths in moral and political philosophy and the philosophy of law. Members of the Department work on and teach a diverse range of topics in this area, both contemporary and historical. Adrienne Martin works in contemporary moral philosophy, and her research ranges from questions in medical and research ethics to abstract metaethical questions; Samuel Freeman specialized in moral and political philosophy and legal philosophy, and has particular interests in the social contract idea and the Rawlsian political philosophy; Kok-Chor Tan does contemporary social and political philosophy, focusing on issues of global justice; and Cristina Bicchieri examines social norms from a game-theoretical perspective. From a more historical perspective, Susan Sauvé Meyer works on ancient Greek moral theory; Charles Kahn teaches ancient political philosophy; and Paul Guyer addresses Kant's moral and political theories.
Our associated faculty also cover many areas of moral, political, and legal philosophy. Colleagues from the Law School contribute to our offerings in legal philosophy, and participate in different ways to the PhD/JD Program. Among their many interests within legal philosophy, Anita Allen writes on privacy law, and gender and the law; William Ewald writes on legal history and international law; Claire Finkelstein works on various aspects of criminal law and Hobbes; and Stephen Perry works on the relationship between legal and moral responsibility and the nature of authority. Thomas Donaldson, Nien-hê Hsieh, Waheed Hussien, and Alan Strudler (all from the Wharton School) add to our teaching in moral and political philosophy and applied ethics. Amy Gutmann (Political Science) has written on topics such as democratic theory, multiculturalism and the philosophy of education; and Arthur Caplan (The Center for Bioethics) and Jonathan Moreno (HSS) work on diverse topics in biomedical ethics.
