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

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

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

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

Discussion is an exchange of knowledge an argument an exchange of ignorance.

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

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

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

Knowledge of what is possible is the beginning of happiness.

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