I think this is the most extraordinary collection of talent, of human knowledge, that has ever been gathered at the White House - with the possible exception of when Thomas Jefferson dined alone.

True knowledge exists in knowing that you know nothing.

Thought is the wind, knowledge the sail, and mankind the vessel.

Knowledge speaks, but wisdom listens.

The greater our knowledge increases the more our ignorance unfolds.

True friendship can afford true knowledge. It does not depend on darkness and ignorance.

Knowledge will forever govern ignorance and a people who mean to be their own governors must arm themselves with the power which knowledge gives.

A good decision is based on knowledge and not on numbers.

I wash my hands of those who imagine chattering to be knowledge, silence to be ignorance, and affection to be art.

The doorstep to the temple of wisdom is a knowledge of our own ignorance.
