Knowledge shrinks as wisdom grows.

Well, there are two kinds of happiness, grounded and ungrounded. Ungrounded happiness is cheesy and not based on reality. Grounded happiness is informed happiness based on the knowledge that the world sometimes sucks, but even then you have to believe in yourself.

The great aim of education is not knowledge but action.

Science is organized knowledge.

Knowledge is going to make you stronger. Knowledge is going to let you control your life. Knowledge is going to give you the wisdom to teach their children. Knowledge is the thing that makes you smile in the face of disaster.
