Authority in the Education of a Human Being by Anthony Esolen (MoJ and Mere Comments)

Professor Esolen is correct to criticize radical egalitarianism. But do teachers have an authority, and does authority have the same meaning as auctoritas? They are superior to students in virtue of the knowledge that they have (or should have). But the do not have the authority of a law-giver, the author of the laws. They may have the authority proper to someone who is reckoned wise or knowledgeable or proficient, someone who has the trust of the students or others. But is not authority then being used in a different sense?
