Philosophy attempts to find highly disciplined, rational ways of dealing with some of the deepest and most difficult issues in human thought and practice—for example, the nature of mind, the possibility or impossibility of knowledge, and fundamental principles of right and wrong. Philosophy thrives on disagreement; even within the Western tradition, no single approach is universally accepted.

Introductory philosophy courses, which are numbered from 100 to 199, are open to all students without prerequisites. Intermediate courses are numbered from 200 to 399; some have prerequisites, while others do not. Students should consult the instructor before taking an intermediate course as their first venture into philosophy. It is a good idea to take a general course in an area of philosophy before taking a specialized one.

One requirement for the major in Philosophy is a two-term introductory sequence in the history of philosophy. Either DRST 003 and DRST 004 (see Directed Studies) or PHIL 125 and PHIL 126 satisfies the requirement. The PHIL 125, PHIL 126 sequence need not be taken in first year, though it is strongly recommended that the requirement be completed before the end of sophomore year.
