All that we know is nothing can be known. 

I wonder whether if I had an education I should have been more or less a fool than I am. 

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.

Give us the child for eight years and it will be a Bolshevist forever.

The ceaseless, senseless demand for original scholarship in a number of fields, where only erudition is now possible, has led either to sheer irrelevancy, the famous knowing of more and more about less and less, or to the development of a pseudo-scholarship which actually destroys its object.

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

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

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.

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.

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? 

The desire of knowledge, like the thirst of riches, increases ever with the acquisition of it.

That which is evil is soon learned.
