Philosophy (PL75)

Since its founding in 1963, the UCSD Philosophy Department has grown to become a nationally ranked department, offering excellent instruction and supervision at the graduate and undergraduate levels. Faculty have a broad range of research interests, with special concentrations in the philosophy of science, ethics and political philosophy, history of philosophy, and epistemology and metaphysics.
The department is strongly committed to interdisciplinary work in philosophy, which graduate students can pursue through joint doctoral studies in the Science Studies Program and in the Department of Cognitive Science. The department has close ties to many other departments and programs on campus including History, Classical Studies, Psychology, Political Science, and the Division of Biological Sciences. Graduates of our Ph.D. program have been successfully placed in top departments across the country and abroad.

Science Studies
The Science Studies Program at UCSD is committed to interdisciplinary investigations. Understanding, interpreting, and explaining the scientific enterprise demand a systematic integration of the perspectives developed within the history, sociology, and philosophy of science. The program offers students an opportunity to work towards such integration, while receiving a thorough training at the professional level in one of the component disciplines.

Students enrolled in the program choose one of the component disciplines for their major field of specialist studies, and are required to complete minor field requirements in the others. The core of the program, however, is a year-long seminar in Science Studies, led by faculty from all participating departments.

Cognitive Science
The interdisciplinary program in Cognitive Science has eight participating departments: Anthropology, Communication, Computer Science and Engineering, Linguistics, Neurosciences, Philosophy, Psychology, and Sociology. Students enroll in one of these departments as their "home department" and also enroll in the Interdisciplinary Program. The degree lists both the home department and Cognitive Science: for example, if the home department is Philosophy, the degree title is "Ph.d. in Philosophy and Cognitive Science." Some additional coursework is required. Please view the web page at
