Those who would learn must suffer. In our own despair, against our will, wisdom comes to us.
Time, waxing old, doth all things purify.
Wisdom cometh by suffering.
The saying goes that the gods leave a town once it is captured.
In the lack of judgment great harm arises, but one vote cast can set right a house.
The one knowing what is profitable, and not the man knowing many things, is wise.
