" The correct way to think about intelligence, in this case, is as a human quality shared by just about everyone, at least until it gets beaten out of us. Not a special gift that is bestowed on only a few. And secondly that it is a functional trait that most people find some way of using in their careers, or whatever it is that they spend their days doing. Sometimes, this trait is put to use doing theoretical physics, but much more often, it’s used in raising children or building houses or operating farm machinery. "
