Repetition is the mother of education.

Rewards and punishment are the lowest form of education.

It is a greater advantage to be honestly educated than honorably born.

All that we know is nothing can be known. 

A school without grades must have been concocted by someone who was drunk on nonalcoholic wine.

A fool’s brain digests philosophy into folly, science into superstition, and art into pedantry. Hence university education.

My own experience is that a certain kind of genius among students is best brought out in bed.

Education has become a prisoner of contemporaneity. It is the past, not the dizzy present, that is the best door to the future.

It is not light that we need, but fire; it is not the gentle shower, but thunder. We need the storm, the whirlwind, and the earthquake.

A whale ship was my Yale College and my Harvard.

What harm is there in getting knowledge and learning, were it from a sot, a pot, a fool, a winter mitten, or an old slipper? 

Anyone who has passed through the regular gradations of a classical education, and is not made a fool by it, may consider himself as having had a very narrow escape.

The great difficulty in education is to get experience out of ideas.
