There is an interesting question. Does the advice "read the masters" also applies to teaching?

My teacher at university pointed me to Moore's method named by great american mathematician Robert Lee Moore. Moore selected students without previous knowledge of the subject and let them "invent" the subject - definition, theorems, proofs.

So great teachers do not "teach masters" but rather teach to "think like masters". If you know how to think, "reading the master" feels more like a dialogue.
