... si rerum usu constat prudentia,
in utrum magis competet eius cognominis honos,

Why is mathematics teaching so poor? "Let us ask why on earth the Philosopher is contented with obscure teaching. We reply that it is just as in the temples, where curtains are used for the purpose of preventing everyone, and especially the impure, from encountering things they are not worthy of meeting. So too Aristotle uses the obscurity of his philosophy as a veil, so that good people may for that reason stretch their minds even more, whereas empty minds that are lost through carelessness will be put to flight by the obscurity when they encounter sentences like these." (The commentator Ammonius (5th c.) On Aristotle's Categories, Prolegomena 7.7-7.14. Translated by S. Marc Cohen and Gareth Matthews)

And to illustrate the point:
... both as head of a computer science department
and then now my second job as a dean, having computer science
departments, I would always get into these discussions with people in
the math department saying, it makes sense that your people teach more
courses per semester than the computer scientists do because you're
still teaching the same courses that you taught 50 years ago, whereas in
the computer science you have to continually redevelop materials so that
you really are covering the most up to date things.
