It seems to me that our scientific revolution was something of a fluke of history. If there had been no Crusades and collisions of Eastern and Western cultures there might have been no Rennaisance. If there had been no Protestant Reformation then people might not have considered other ways of looking at the world. Burning people at the stake puts a real damper on people's creativity. Some might argue that the one great invention of the printing press made progress all but inevitable. I just don't know.
