Teaching as a teacher is a horrible thing to do to a student.
For a start, it's an arrogant position to start from. How do you know they don't know? When you project ignorance onto another person, it's a pretty egonic position.
"I am the one who knows."
How does it feel to be taught by someone like that?
Of course, SOME kind of teaching is all about information, BUT NOT our work. There is no curiculum for Alexander's discovery.
How can you learn what you already know?
