It is an interesting and well-thought out essay, but while I emphatically agree with the second passage you quoted, I question what it means in the first one for those in the Middle Ages to have "known" where they came from, were going, and why. Can we call this "knowledge" true? He makes statements that their worldview was ordered and comprehensible, and that the inflow of information from the printing press muddled and unraveled things. I say that it is vital to be able to filter all the input we get today, but having a limited amount of input is not the same thing. He says, "there was a scarcity of information but its very scarcity made
it both important and usable." So regardless of what the information was, it had value. I don't like that. Information needs to stand on its own merits, or be filtered out. He states that Galileo and Kepler disturbed folks' faith concerning their place in the universe with the heliocentric model. They also revealed truth to us.
