Don't be afraid to ask questions. People have a lot of knowledge.

Knowledge is a weapon. I intend to be formidably armed.

Our knowledge is a receding mirage in an expanding desert of ignorance.

The opinion is the medium between knowledge and ignorance.

The end of all knowledge should be service to others.

Knowledge is not a guarantee of good political behavior, but ignorance is a virtual guarantee of bad behavior.

Freedom is never given; it is won. 

Knowledge will give you power, but character respect.

Knowledge is knowing that a tomato is a fruit. Wisdom is knowing not to put it in a fruit salad.

Having knowledge but lacking the power to express it clearly is no better than never having any ideas at all.
