Plato's "Apology": an awesome read. :) Socrates explains that in his investigations, everyone knows a lot of things - even the common workman knows many things the rich and powerful don't know. However, when conversing with someone considered "wise", he realises that this person won't admit that they don't know everything. Socrates understands that he (himself, Socrates) will never know everything, and as a result knows more, and therefore is the "wiser man".

Hi... Socrates believed the best way for people to live was to focus on self-development rather than the pursuit of material wealth. He always invited others to try to concentrate more on friendships and a sense of true community, for Socrates felt this was the best way for people to grow together as a "wiser man"...
