Who except the gods can live without any pain?
He who learns must suffer. And even in our sleep pain that cannot forget falls drop by drop upon the heart, and in our own despair, against our will, comes wisdom to us by the awful grace of God.
Wisdom comes alone through suffering.
It is best for the wise man not to seem wise.
I willingly speak to those who know, but for those who do not know I forget.
For know that no one is free, except Zeus.
