Wise Man
He knows where the idea that alchemists know everything comes from. Alchemists spend their lives in study, researching esoteric mysteries, experimenting with the very fabric of reality. No wonder people look at them and assume they've somehow tapped into wisdom the rest of humanity can't touch.
Ed knows it's a lie. He knows that alchemists are no wiser than anyone else, and often more foolish. Alchemy is no more inherently connected to wisdom than it is to building automail.
Sometimes he thinks that just understanding that he is far from wise himself is all the wisdom he needs right now.
