"You have to be confused before you can reach a new level of understanding anything." -- Dudley Herschbach, Nobel Prize winning chemist from Harvard
If one were never confused, one would never need to learn anything.
Now, if I can just convince my students that confusion is not necessarily a bad thing -- help them learn to use it as a catalyst for learning. But it means a willingness to trust the one who brings on the confusion and an ability to spend a certain amount of time (maybe a little, but maybe a lifetime) in a state of negative capability.
