Mm, in my world mages were compelled to keep knowledge of magics a secret. The more people who knew about magic the more it would dilute its power. You could say that the more the light of science expands is equal to the amount that the shadow of Mystery and its magics recede. As such the Association's first rule is to keep the truth of magecraft away from those who aren't already mages.

[First rule about fight club is to not talk about fight club, ya hear?]
