I know nothing except the fact of my ignorance.
There is only one good, knowledge, and one evil, ignorance.
Having the fewest wants, I am nearest to the gods.
There are two sides to every question.
Man is the measure of all things.
In soft regions are born soft men.
Labor to keep alive in your breast that little spark of celestial fire called conscience.
This is the bitterest pain among men, to have much knowledge but no power.
