The rich countries' problem is rigidity and the poor countries' problem is capacity. Then we all share a problem that was best articulated by the philosopher Ken Wilber. He's got this theory that there are basically 10 levels of consciousness—the way we view ourselves, the way we view others—and that it's almost impossible for people to keep up with what circumstances require. If you live in an interdependent world, you have to believe as a starting premise—it doesn't mean you'll never go to war, doesn't mean you'll never fight, you can't be naive or stupid, doesn't mean we shouldn't be out there trying to get the leaders of Al Qaeda—but you have to believe that in an interdependent world, what we have in common is more important than our interesting differences. -Bill Clinton
