What I mean is the power of imagination. Human imagination is all that stands between us and still living in caves. It's the source of every form of human achievement in literature, in science, in the arts, in human relationships, in business, in the economy. It's what has given us six thousand languages currently spoken on earth. It's what gave us the Sistine Chapel, the music of Bach, the music of Mozart, the great traditions of the East, Confucianism, every world philosophy-- it is at the root of every distinctively human achievement, and it's the one thing that I believe we're almost systematically jeopardizing in the way we educate our children and ourselves. So I want to speak a little bit about that, and really to put three ideas to you. I know that looks like five, but that was a gesture, okay?
