I read and think well in the morning. It’s a good time to think about lectures. I grade poorly, because I spend too much time on each paper.
Perhaps a good way to start philosophical discussions in class, to prompt thought and curiosity, is to ask the students, “in general, what do most people think about…” But just be ready to encounter ideas that aren’t anticipated, or even sensical. Truly, it is a learning experience when an answer is given that would seem a priori improbable.
