Marcus Tullius Cicero

Never go to excess, but let moderation be your guide.

If you pursue good with labor, the labor passes away but the good remains; if you pursue evil with pleasure, the pleasure passes away and the evil remains.

Never injure a friend, even in jest.

A friend is, as it were, a second self.

Any man is liable to err, only a fool persists in error.

Nothing is so unbelievable that oratory cannot make it acceptable.

As fire when thrown into water is cooled down and put out, so also a false accusation when brought against a man of the purest and holiest character, boils over and is at once dissipated, and vanishes and threats of heaven and sea, himself standing unmoved.

The authority of those who teach is often an obstacle to those who want to learn.

The function of wisdom is to discriminate between good and evil.

True nobility is exempt from fear.

The precepts of the law are these: to live honestly, to injure no one, and to give everyone else his due.

Knowledge which is divorced from justice, may be called cunning rather than wisdom.

Natural ability without education has more often attained to glory and virtue than education without natural ability.

True glory takes root, and even spreads; all false pretences, like flowers, fall to the ground; nor can any counterfeit last long.

Let us not listen to those who think we ought to be angry with our enemies, and who believe this to be great and manly. Nothing is so praiseworthy, nothing so clearly shows a great and noble soul, as clemency and readiness to forgive.

Nothing is more unreliable than the populace, nothing more obscure than human intentions, nothing more deceptive than the whole electoral system.

The spirit is the true self. The spirit, the will to win, and the will to excel are the things that endure.

Laws are silent in time of war.

The pursuit, even of the best things, ought to be calm and tranquil.

The wise are instructed by reason, average minds by experience, the stupid by necessity and the brute by instinct.
