"Man only finds true intelligence in the realization of his ignorance"
or something along those lines.
Basically meaning that you can have all the wisdom and intelligence in the world, but unless you realize that you can't be right all the time you are are ignorant... therefor, not truelly intelligent. Where as a person who realizes they are not always right knows TRUE intelligence.
Furthermore, intelligence doesn't necessarily come with the amount of wisdom, but rather in the way that you apply it.
