Philosophy can make people sick.

In general, what is written must be easy to read and easy to speak; which is the same.

We become just by the practice of just actions, self-controlled by exercising self-control, and courageous by performing acts of courage.

The happy man . . . will be always or at least most often employed in doing and contemplating the things that are in conformity with virtue. And he will bear changes of fortunes most nobly, and with perfect propriety in every way.

Humor is the only test of gravity, and gravity of humor; for a subject which will not bear raillery is suspicious, and a jest which will not bear serious examination is false wit.

Goodness is to do good to the deserving and love the good and hate the wicked, and not to be eager to inflict punishment or take vengeance, but to be gracious and kindly and forgiving.

Most persons think that a state in order to be happy ought to be large; but even if they are right, they have no idea of what is a large and what a small state.... To the size of states there is a limit, as there is to other things, plants, animals, implements; for none of these retain their natural power when they are too large or too small, but they either wholly lose their nature, or are spoiled.
