填空题 It is a human world, but one that is human in ways no one expected. The image it reveals is not the worn and battered face that stares from Leonardo"s self-portrait, much less the one that stares, bleary and uninspired, every morning from the bathroom mirror. These are the faces of history. It is, rather, the image of an eternally playful and eternally youthful power that makes order whether order is there or not and that having made one order is quite capable of putting it aside and creating an entirely different one the way a child might build one structure from a set of blocks and then without malice and purely in the spirit of play demolish it and begin again. It is an image of the power that made humanity possible in the first place.
