So, you say something like: "Involving another person in a scheme or a plan that she couldn't or wouldn't rationally consent to if she knew the whole story is to use her will in a way that disrespects her autonomy." And then from the corner of the room, you hear a student mutter, "...according to him," (referring here to Kant, of course).
I pride myself on being an empathetic and patient teacher, especially of beginning students. But I have to say that this particular piece of classroom behavior drives me to fits of catastrophic irrationality. Catastrophic because I find it so unrelentingly annoying that I can't even articulate why it drives me so nutty.
So, fellow teachers: 1) help me by speculating about why I find this behavior so distracting and unproductive; 2) do you have a particular strategy for this particular phenomenon? Is it successful or not? Why or why not...I mean, that is, according to you...
