Intelligance.

What is it about intelligane that makes one person smart and the other stupid?

Is it possible for the smart ones to learn everything and the stupid ones to learn nothing? What if the smart ones can't learn any more but the stupid onces can? So who is really the smart one? Was there ever a smart one to begin with?

Just because someone is stupid doesn't mean that they can't learn. Being ignorant means you can't and won't learn. Just becasue someone isn't as smart as most doesn't meant that they don't have intelligance either way. Sometimes being too smart can be a bad thing. If you are too smart, then what is there left for you to learn? Is there anything left for you to learn? If you are stupid, then you can grow. Being stupid means that you can learn something.

Being stupid isn't a bad thing.
