The master's degree in philosophy is designed for students who intend to pursue a doctorate in philosophy as well as for those who seek the master's as a terminal degree, either in pursuit of their intellectual interests or to further their professional expertise. Students choose a master's degree with a focus on traditional and contemporary philosophy or one of three concentrations: ethics and public affairs, philosophy and cultural theory, or philosophy and public affairs. The concentration in philosophy and public affairs allows students in the graduate program in philosophy at Moscow's Higher School of Economics to also earn a degree from George Mason. All offerings provide grounding in the history of philosophy, ethics, metaphysics, epistemology, contemporary continental thought, contemporary analytic philosophy, and philosophy of science.

An accelerated master's option is available to students in the bachelor's program.  See Philosophy, BA/Philosophy, Accelerated MA for specific requirements.
