I willingly speak to those who know, but for those who do not know I forget.

God always strives together with those who strive.

To mourn and bewail your ill-fortune, when you will gain a tear from those who listen, this is worth the trouble.

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.

For know that no one is free, except Zeus.

Don't you know this, that words are doctors to a diseased temperment?
