The more I see the less I know for sure.

John Lennon

What is important is not the quantity of your knowledge but its quality. You can know many things without knowing the most important.

Learning without thought is labor lost; thought without learning is perilous.

He who knows all the answers has not been asked all the questions.

Study without reflection is a waste of time; reflection without study is dangerous.

Knowledge is merely brilliance in organization of ideas and not wisdom. The truly wise person goes beyond knowledge.

Real knowledge is to know the extent of one's ignorance.
