If you could invite four people-living or dead- to a dinner party, who would they be?
While I'm sorely tempted to invite people who wouldn't get along (such as Adolf Hitler and Moshe Dayan), I think that would result in a very unpleasant dinner party. I think I might go with great scientists and philosophers. Aristotle, Carl Sagan, Leonardo da Vinci, and Charles Darwin would make for fascinating conversation. Although I imagine I'll need to bring a lot of wine for Aristotle, as he's not going to like finding out how wrong he was about everything.
