Research is creating new knowledge.

There is nothing new in the world except the history you do not know.

Knowledge rests not upon truth alone, but upon error also.

The aim of education is the knowledge, not of facts, but of values.

Where there is no vision, there is no hope.

Failure will never overtake me if my determination to succeed is strong enough.

Knowledge is not skill. Knowledge plus ten thousand times is skill.

I never learn anything by talking. I only learn things when I ask questions.

In youth we learn; in age we understand.

Where there is shouting, there is no true knowledge.
