I got into an argument with someone on irc one night - it lasted about 2 hours - over the definition of intelligence. I maintained that it's not only what you know, but the ability to obtain the "know" from resources. You are born with certain instincts. That is undeniable. But you have to learn virtually everything else. You learn from what? Resources. Your parents, books, peers, society, television, etc. Unintelligent people, stupid if you will, to me are the ones that either don't have the capacity to learn, or just don't want to.
