a book review and a proposed humanitarian use for a time machine

One of my favorite games to play while studying the history of science is to match the ideas and rhetoric of openly anti-science modern public figures to the era of history in which they and their ideas would feel most at home. I think if we really set our minds to it, and we invent time travel, we can find a place in history for even the most temporally-displaced persons. That way, when we find ourselves thinking, "Why, his ideas are positively medieval, does he even know what year it is?" we need not concern ourselves with the lengthy and painful process of bringing a medieval thinker into the modern era. We only need to identify which century would be a more suitable home, and send him there.
