"[T]he philosopher presides only as a moderator, to maintain the conversation on a philosophical footing. The discussion is thoughtful but nontechnical. You will be challenged to defend your beliefs or opinions, but you will not be asked to refer to a list of philosophy books in order to support your views. In fact, the opposite is usually true: Instead of showing off your erudition by referring to great works you may have studied, you will be obliged to think for yourself, to give your own reasons for the views you hold." via ed's weblog
