Who is so stupidly curious....

For do teachers profess that it is their thoughts which are perceived and grasped by the students, and not the sciences themselves which they convey through thinking? For who is so stupidly curious as to send his son to school that he may learn what the teacher thinks?...Those who are pupils consider within themselves whether what has been explained has been said truly; looking of course to that interior truth, according to the measure of which each of us is able. Thus they learn, and when the interior truth makes known to them that true things have been said, they applaud... (St. Augustine, On the Teacher)
