Since all of us desire to be happy, and since we evidently become so on account of our use—that is our good use—of other things, and since knowledge is what provides this goodness of use and also good fortune, every man must, as seems plausible, prepare himself by every means for this: to be as wise as possible. Right?

Better to do a little well, then a great deal badly.

He is the richest who is content with the least.

I know one thing, that I know nothing.

Wisest is he who knows he knows not.
