Happiness exists on earth, and it is won through prudent exercise of reason, knowledge of the harmony of the universe, and constant practice of generosity.

The only way to be totally free is through education.

Love is the bond between men, the way to teach and the center of the world.

It is a sin not to do what one is capable of doing.

In a time of crisis, the peoples of the world must rush to get to know each other.

People can only be free if they are truly educated.

The truthe wakes up once and never dies.
