It is the supreme art of the teacher to awaken joy in creative expression and knowledge.

Behind the parents stands the school, and behind the teacher the home.

A teacher can never truly teach unless he is still learning himself. The teacher who has come to the end of his subject, who has no living traffic with his knowledge but merely repeats his lesson to his students, can only load their minds, he cannot quicken them.

Every truth has four corners: as a teacher I give you one corner, and it is for you to find the other three.

In the practice of tolerance, one's enemy is the best teacher.

Acquire new knowledge whilst thinking over the old, and you may become a teacher of others.
