The study of cultural history can appeal to students with an array of interests. Courses may cover subjects such as anthropology, philosophy, religion, the arts, gender studies and race, though many other topics can also be explored.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
