Authority is no source for Truth.

The excellence of a thing is related to its proper function.

The virtue of the good man is necessarily the same as the virtue of the citizen of the perfect state.

He is courageous who endures and fears the right thing, for the right motive, in the right way and at the right times.

When there is no middle class, and the poor greatly exceed in number, troubles arise, and the state soon comes to an end.

The souls ability to nourish itself lies in the heart.

The man who is truly good and wise will bear with dignity whatever fortune sends, and will always make the best of his circumstances.
