"I know nothing, I hear nothing, I see nothing." --Sergeant Schultz, Hogan HeroesKnowing that you know nothing is attributed to Socrates by Plato, but no one seems to know if that is true or not. Which kind of confirms the premise that no one knows anything. So does the Internet and Fox News.
It is one of the ironies of aging (along with hair growth in random places) that experience finally teaches you that you know nothing. I have, in fact, become an expert at knowing nothing. I can now state with confidence when asked most questions that I haven't got a clue. I take comfort now in my lack of knowing. When someone asks me for directions, I can respond, "I don't know," instead of pointing and gesturing and conjecturing and sending the person off to god knows where because I don't want to admit to not knowing.
