We keep falling into the same ditches, you know? I mean, we learn more and more about the physical universe, more about our own bodies, more technology, but somehow, down through history, we go on building empires of one kind or another, then destroying them in one way or another. We go on having stupid wars that we justify and get passionate about, but in the end, all they do is kill huge numbers of people, maim others, impoverish still more, spread disease and hunger, and set the stage for the next war. And when we look at all of that in history, we just shrug our shoulders and say, well, that's the way things are. That's the way things always have been.
