Philosophy at USC

At USC, we believe that philosophy’s task grows out of what has always been its central mission—to help lay the conceptual foundations for advances in our theoretical knowledge of the universe and ourselves, while also providing practical wisdom needed for virtuous and meaningful lives. Thus, it is not the study of a frozen historical canon, offering a smorgasbord of previous responses to unanswerable questions yielding no genuine knowledge. On the contrary, it is what its greatest practitioners have always taken it to be—an unending quest to generate new philosophical questions, while offering better answers to old questions raised by our illustrious predecessors from Socrates and Plato to Hume, Kant, Russell, Wittgenstein, and beyond.

Philosophy investigates some of the oldest, most universal and fundamental questions that human beings ask, in a rigorous and disciplined application of both logic and imagination. Studying philosophy develops skills in logic and critical thinking that apply to every field and profession. In our undergraduate courses, students can study a wide range of topics including moral controversies, the principles of social justice, the grounds for moral, legal, and political obligation, the scope and limits of human knowledge, the foundations of science, the nature of reality, space, time, consciousness and freedom, the existence or non-existence of God, as well as the history of philosophical thought about these and many other topics. These courses are taught by our world-renowned and award-winning faculty who collectively make the School of Philosophy at USC ranked one of the top ten graduate programs nationally and internationally.

Interdisciplinary Connections

Because we believe that philosophy, properly understood, is not an isolated discipline, but the partner of all disciplines, our faculty demonstrate a commitment to interdisciplinary excellence both at the graduate and undergraduate levels. Our faculty interact with other units and we offer undergraduates three interdisciplinary philosophy-centered majors—philosophy, politics, and law, philosophy and physics (PP), and philosophy, politics, and economics (PPE)—in addition to our standard philosophy major.

Our PhD students

The PhD program offers the opportunity to work towards a doctorate in philosophy in a supportive and collaborative community of graduate students, faculty and scholars. Our PhD students regularly publish in top-rated journals and volumes, finish the program within 5-7 years, and are well-supported in their search for academic and non-academic positions before and after graduation. Head to Our Graduate Program for details of the program including how to apply.
