After spending fifty years teaching seniors in four countries across the world, I learned something about intelligence. It's a unique quality, an abnormal ability of the brain to see and understand the relationships between what can be learned and the world. Intelligence is not one quality but comes in many forms and never ceases to amaze. Scoring AP scripts offered me a window into the minds of young Americans some of whom at 18 have amazing understanding and knowledge as they interpret difficult ideas. Their minds can make connections way beyond their tender years. This intelligence manifests itself in Aristotle, Shakespeare, Newton, Einstein and any of the great minds of the past where connections were made and new thinking changed history and human understanding. Only a few are specially gifted in this way. But the paradox of knowledge, is that more you learn, the less you know. The President has talked frequently over many years how intelligent or smart he is which is really saying quite the opposite.
