Drawing the metaphor of the early attempts to fly: the man going off of a very high cliff … and the guy’s flapping the wings and the wind is in his face, and this poor fool thinks he’s flying, but, in fact, he’s in free fall, and he just doesn’t know it yet because the ground is so far away… That’s the way our civilization is. The very high cliff represents the virtually unlimited resources we seem to have when we began this journey … Our civilization is not flying because it’s not built according to the laws of aerodynamics for civilizations that would fly. And, of course, the ground is still a long way away, but some people have seen that ground rushing up sooner than the rest of us have.
