Every lesson we teach embodies a theory of authority:
- About the teacher's authority
- About the lesson's authority
- About the student's authority
- About what authority itself is
The purpose of what I can consider "a true lesson" is to give authority to the person learning it.
The essence of a lesson is, therefore, the handing on of authority from a magister (teacher) or auctoritas (author, authority) to the discipulus (learner, disciple).
