Repetition is the mother of education.

Real education must ultimately be limited to men who insist on knowing—the rest is mere sheep herding.

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

Education is a weapon whose effects depend on who holds it in his hands and at whom it is aimed.

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

In large states public education will always be mediocre, for the same reason that in large kitchens the cooking is usually bad. 

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

Knowledge is an ancient error reflecting on its youth. 

That which is evil is soon learned. 

In the first place God made idiots. This was for practice. Then he made school boards.

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.

Human history becomes more and more a race between education and catastrophe.

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