Knowledge is the eye of desire and can become the pilot of the soul.

Knowledge of what is possible is the beginning of happiness.

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

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

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.

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

Knowledge of what is does not open the door directly to what should be.

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

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