“No man should escape our universities without knowing how little he knows.”

“What I learned in University was how little I know.”

“A man who knows how little he knows is well, a man who knows how much he knows is sick. If, when you see the symptoms, you can tell, Your cure is quick.A sound man knows that sickness makes him sick and before he catches it his cure is quick.”

“The reality of the ordinary progress of Christian understanding should not escape our notice: early believers "know no answers"; immature believers "know all the answers"; and mature believers "know the limits of our answers.”

“He who knows best knows how little he knows.”

“It is not necessary for the whole of nature to take up arms to crush him: a puff of smoke, a drop of water, is enough to kill him. But even if the universe should crush him, man would still be more noble than that which destroys him, because he knows that he dies and he realizes the advantage which the universe possesses over him. The universe knows nothing of this.”
