QUOTE : Whether a civilization fares well during a crisis has a great deal to do with how the ordinary, nonscientist citizen responds. A lot of the measures taken against the plagues discussed in this book will seem stunningly obvious. You should not, for instance, decide diseased people are sinners and burn them at a literal or metaphorical stake, because it is both morally monstrous and entirely ineffective. Everyone would probably theoretically agree with this statement. But then a new plague crops up, and we make precisely the same mistakes we should have learned from three hundred years ago.
