Lots of really great advise in this thread that tends to get forgotten by students when looking for a college. Searching for of “top” schools are a great starting point but you need to always dig behind the rankings and look at the criteria that is most meaningful to you.
On top of the focus of the program (Undergrad vs pHD), size of actual program should be considered. Do you want a school like UPenn that have about 500 undergrad Philosophy students or a more smaller focused school like Williams. Whats the goal after college? Law School? Banking? Teaching? becoming a modern Philosopher?
