“So, listen, to yourself and to those with whom you are speaking. Your wisdom then consists not of the knowledge you already have, but the continual search for knowledge, which is the highest form of wisdom. It is for this reason that the priestess of the Delphic Oracle in ancient Greece spoke most highly of Socrates, who always sought the truth. She described him as the wisest living man, because he knew that what he knew was nothing.
Assume that the person you are listening to might know something you don’t.”
