"People who lead a lonely existence always have something on their minds that they are eager to talk about" — Anton Chekhov

A mind that is stretched by a new experience can never go back to its old dimensions

A human being is not attaining his full heights until he is educated

It is a thousand times better to have common sense without education than to have education without common sense

It is the mark of an educated mind to be able to entertain a thought without accepting it

There is a wisdom of the head, and a wisdom of the heart.

Nine-tenths of wisdom is being wise in time
