The years wrinkle our skin, but lack of enthusiasm wrinkles our soul.

wealth does not bring goodness, but goodness brings wealth and every other blessing, both to the individual and to the state

I will not yield to any man contrary to what is right, for fear of death, even if I should die at once for not yielding.

I know what I do not know.

Marry a good woman, and be happy the rest of your life. Or, marry a bad, and become a good philosopher

May I consider the wise man rich, and may I have such wealth as only the self-restrained man can bear or endure.

Wisdom belongs in wonder.
