It is the province of knowledge to speak, and it is the privilege of wisdom to listen.

Knowledge which is acquired under compulsion obtains no hold on the mind.

Knowledge is power. Information is liberating. Education is the premise of progress, in every society, in every family.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.

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

Today knowledge has power. It controls access to opportunity and advancement.

If knowledge can create problems, it is not through ignorance that we can solve them.

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

All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.

Jealousy is all the fun you think they had.
