The University of Maine was a premier engineering school when I attended, and the school of philosophy (headed by Erling Skorpen) was top-notch. This stuff changes all the time. It's pretty dynamic.
What, if you don't mind me asking, would you do with a degree in philosophy. It doesn't seem like something that is very desirable in todays work place.
I've heard that the University of Pittsburgh has a good graduate program in the philosophy of physics. They do not have an undergrad program in this major, but it may still be worth checking out. I can't vouch for their philosophy department, but I have been working in the physics department there this summer and I'm enjoying it a lot. Good luck in your school search!
