Brown's Ph.D. program has longstanding strengths in epistemology, philosophy of mind, metaphysics, ethics, and history of philosophy; and we have more recently developed additional strengths in political philosophy and in aesthetics.

For undergraduates with a deeper interest in the subject, there are programs leading to the A.B. degree, the A.B. degree with honors, and the combined A.B.-M.A. degrees. As well as the standard philosophy concentration, there is an interdisciplinary concentration in Physics and Philosophy. The standard concentration also encourages an inter-disciplinary approach by allowing students to apply related courses in other departments towards the fulfillment of their concentration requirements. The requirements also allow ample room for concentrators to pursue their individual interests, as these develop.
