Democritus

Many who have not learned wisdom are yet wise.

Happiness does not reside in possessions, and gold, happiness dwells in the soul.

The man who is fond of generally laughing at others is himself deserving of ridicule.

Life is a journey, not a destination.

The brave man is not he who is never afraid, but he who conquers fear.

Medicine heals diseases of the body, wisdom frees the soul from passions.

The world is a stage, and all the men and women merely players.

The sweet and the bitter are in opinion; the hot and the cold are in opinion; color is in opinion; in truth there are only atoms and the void.

The man who is always laughing is a fool.

To a reasonable man, a small thing is great, but to a fool, the greatest is small.

The animal that has the most fear has the most wisdom.

Men have made an idol of fortune, to excuse their own want of judgment.

The fool is known by his speech; and the wise man by silence.

The whole earth is a grave for those who are not wise.

The man who is always seeking for something new is never satisfied.

The greatest pleasure is to do what you ought to do.

The man who is always busy is never free.

The man who is always talking is never heard.

The man who is always right is always wrong.

The man who is always happy is never sad.
