The whole Earth is at the hand of the wise man, since the fatherland of an elevated soul is the Universe.
Everywhere man blames nature and fate yet his fate is mostly but the echo of his character and passion, his mistakes and his weaknesses.
Medicine heals diseases of the body, wisdom frees the soul from passions.
Nothing exists except atoms and empty space; everything else is opinion.
One should practice much sense, not much learning.
The man enslaved to wealth can never be honest.
