Word is a shadow of a deed.

The brave man is not only he who overcomes the enemy, but he who is stronger than pleasures.

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

We think there is color, we think there is sweet, we think there is bitter, but in reality there are atoms and a void.

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

The wise man belongs to all countries, for the home of a great soul is the whole world.

Envy creates the beginning of strife.
