There is nothing fruitful except sacrifice.

Neither genius, fame, nor love show the greatness of the soul. Only kindness can do that.

Duty is the grandest of ideas, because it implies the idea of God, of the soul, of liberty, of responsibility, of immortality.

In relations between the rich and the strong, between the rich and the poor, between the master and the servant, it's liberty that grinds down, and the law which liberates.

The mind sees, the will commands, the man acts. What is it then to act? To act is to produce something. If you have produced nothing--if no result has been the fruit of your will, you have done nothing.

Nothing wounds a friend like a want of confidence.

As to the lawful pleasures of the mind, the heart, or the senses, indulge in them with gratitude and moderation, drawing up sometimes in order to punish yourself, without waiting to be forced to do so by necessity.
