The art and science of asking questions is the source of all knowledge.
The good life is one inspired by love and guided by knowledge.
The aim of education is the knowledge not of facts but of values.
William Ralph Inge
Knowledge will give you power, but character respect.
The doorstep to the temple of wisdom is a knowledge of our own ignorance
Faith is a knowledge within the heart, beyond the reach of proof.
