Conversation is an essential part of the philosophical life. I try to approach teaching with this in mind. In my own education, I always got the most from courses that had the structure of dialogue: the give and take of ideas, the persistant collective examination of arguments and their reach, and, perhaps most importantly, the sense that we (the students) were engaged and active participants in a conversation. I try to structure my classes the same way.
I’m no longer surprised that I learn something every time I teach a course.
