When you’re doing philosophy, don’t be afraid to sound dumb, or simpleminded. If, for example, what somebody says sounds to you so obviously mistaken that you conclude that you must be missing something, keep alive in your mind the alternative conclusion, which is that they are missing something, or seeing something that isn’t there, even if they are the teacher. Some of the most successful philosophical interventions that I’ve witnessed have been a matter of pointing out that the emperor’s not wearing any clothes.
