Old age takes from the man of intellect no qualities save those that are useless to wisdom.

Men must be either the slaves of duty, or the slaves of force.

If fortune wishes to make a man estimable, she gives him virtues; if she wishes to make him esteemed, she gives him success.

The talkative man speaks from his mouth, the eloquent man speaks from his heart.

Old age deprives the intelligent man only of qualities useless to wisdom.

One man finds in religion his literature and his science, another finds in it his joy and his duty.

Man is born with the faculty of speech. Who gives it to him? He who gives the bird its song.

What a man knows only through feeling can be explained only through enthusiasm.
