<p>While Michigan is very large, Philosophy attracts very few students. Intro classes may be large, and some may even be taught by TAs. However, intermediate and advanced level classes will be taught by faculty and classes should be small, with plenty of interaction with faculty. </p>
<p>I think you should seek the advice of bclintonk. He is a regular poster who did his undergraduate studies in Philosophy at Michigan and went on to get a PhD at another top Philosophy department. While he knows much about the department at Michigan, he also has a healthy respect for LACs.</p>
