I’m thinking of double-majoring. Bad idea?
No; in fact philosophy works very well as half of a double major. The trick, as with any double major, is in meeting a large number of requirements in a limited amount of time. Planning makes a big difference. Go to Campbell Hall and ask for the double-major forms. They are a bit daunting, but they are actually very useful for figuring out the details of exactly how to meet two sets of major requirements. Fill the forms out as best you can, and then go in to see the faculty advisors in philosophy (see above for names) and the other field. The advisors will help you spot potential problems and may be able to suggest solutions.
