The purpose of learning is growth, and our minds, unlike our bodies, can continue growing as we continue to live.
Mortimer AdlerReading a book should be a conversation between you and the author. Presumably he knows more about the subject than you do; if not, you probably should not be bothering with his book. But understanding is a two-way operation; the learner has to question himself and question the teacher, once he understands what the teacher is saying. Marking a book is literally an expression of your differences or your agreements with the author. It is the highest respect you can pay him.
Mortimer AdlerLove consists in giving without getting in return; in giving what is not owed, what is not due the other. That's why true love is never based, as associations for utility or pleasure are, on a fair exchange.
