Democritus

The universe is change; our life is what our thoughts make it.

Do not trust all men, but trust men of worth; the former course is silly, the latter a mark of prudence.

Men should strive to think much and know little.

The first principles of the universe are atoms and empty space; everything else is merely thought to exist.

Many much-learned men have no intelligence.

Good breeding in cattle depends on physical health, but in men on a well-formed character.

It is greed to do all the talking but not to want to listen at all.

He who does wrong is more unfortunate than he who is wronged.

It is godlike ever to think on something beautiful and on something new.

The man who is fortunate in his choice of a son-in-law gains a son; the unfortunate one loses a daughter.

Nature and instruction are similar; for instruction transforms the man, and in transforming, creates his nature.

To a wise man, the whole earth is open; for the native land of a good soul is the whole earth.

Hope of ill gain is the beginning of loss.

It is hard to fight with desire; but to overcome it is the mark of a rational man.

The animal needing something knows how much it needs, the man does not.

One should emulate the deeds and actions of virtue, not the words.

The envious man torments himself like an enemy.

Throw moderation to the winds, and the greatest pleasures bring the greatest pains.

It is better to examine your own faults than those of others.

A life without festivity is a long road without an inn.
