A teacher who is not dogmatic is simply a teacher who is not teaching.

A professor is someone who talks in someone else's sleep.

Excellence is a better teacher than mediocrity. The lessons of the ordinary are everywhere. Truly profound and original insights are to be found only in studying the exemplary.

I cannot emphasize enough the importance of a good teacher.

The whole art of teaching is only the art of awakening the natural curiosity of young minds for the purpose of satisfying it afterwards.
