I'm looking into the program at Villanova. They specialize in the "continental" tradition that I am most interested in. Here is a brief statement on the two major "styles" or methods of philosophy by Jamie Smith, a Dooyeweerdian graduate of Villanova's Ph.D. program.
"Continental" and "analytic" philosophy are distinguished by "a certain “method” of doing philosophy which is undergirded by certain prephilosophical commitments regarding human nature, ontology, etc. In fact, we might say that what distinguishes continental from analytic philosophy is precisely the fact that the former recognizes the formative power of prephilosophical commitments and the contextuality of philosophizing, whereas analytic philosophy (largely) proceeds on an assumption regarding the ahistoricity of propositions."
