Foolishness

Is it more foolish to not know what is wrong and and continuing on?
Or is it more foolish to know what is wrong and do nothing about it?
Is it too foolish to know what is wrong but not have the bravery to right it?
Is it foolish to take advice from a fool?
Or is it foolish to even contemplate listening to a fool?
Even a fool would have some expertise....at least in foolishness no?
