The telephone book is full of facts, but it doesn't contain a single idea. - Mortimer J. Adler

Unlike many of my contemporaries, I never write books for my fellow professors to read. I have no interest in the academic audience at all. I'm interested in Joe Doakes. A general audience can read any book I write – and they do.

The books to be read should not be limited to those written in English.... Instead it should be devoted to the great works of history, biography, philosophy, theology, natural science, social science, and mathematics, as well as the... tradition of Western literature -- in English translation... Its aim should not be a survey of Western civilization, but an effort to understand the basic ideas and issues in Western thought.

It is obvious that teaching is a very special art, sharing with only two other arts, agriculture and medicine, an exceptionally important characteristic A doctor may do many things for his patient, but in the final analysis, it is the patient himself who must get well, grow in health. The farmer does many things for his plants or animals, but in the final analysis, it is they that must grow in size and excellence. Similarly, although the teacher may help his student in many ways, it is the student himself who must do the learning. Knowledge must grow in his mind if learning is to take place.
