Men in no way approach so nearly to the gods as in doing good to men.

Not to know what has been transacted in former times is to be always a child. If no use is made of the labors of past ages, the world must remain always in the infancy of knowledge.

While there's life, there's hope.

The spirit is the true self.

When you wish to instruct, be brief that men's minds take in quickly what you say, learn its lesson, and retain it faithfully. Every word that is unnecessary only pours over the side of a brimming mind.

Not to know the events which happened before one was born, that is to remain always a boy.
