“We have no means of understanding a fraction of the thought and science and philosophy and law that have gone to make that outside world. We simply accept it. We have grown up paying tribute to it, and that is all the most of us can do. We feel of the great world that it is simply there, something for the lucky ones to explore, and then only at the edges. It never occurs to us that we might make some contribution to it ourselves. And that is why we miss everything.”
