We don't have a revolution, and we don't have the time for evolution, where does it come from? It must come from some kind of shared experience that everybody agrees with.
You can't have an industrial revolution, you can't have democracies, you can't have populations who can govern themselves until you have literacy. The printing press simply unlocked literacy.
One of the things we know now that we didn't know then, is that revolutions are very painful to a lot of people. And that at the stage that we have evolved to now, a revolution would be extremely painful.
