It makes sense for students minoring in philosophy to take the required history sequence (PHIL 260-261) early. It provides excellent background for your other courses. It might be a good idea to take an introductory course (PHIL 100, PHIL 110, or PHIL 200) first, before taking the history sequence. While this is not absolutely essential, if you’ve had no previous experience with philosophy, then the sense you’ll get from an introductory course of what’s involved in philosophical thinking will help you substantially to get your bearings in the courses on ancient and modern philosophy.
All other PHIL courses can be counted as electives by philosophy minors. While the only course in philosophy that carries a prerequiste is PHIL 341—Formal Logic II, PHIL 385 (Epistemology), PHIL 390 (Metaphysics), and PHIL 495 (Advanced Seminar) should probably be taken only after completion of the history sequence.
