over two thousand years ago, the Chinese strategist Sun-tzu came to believe that listening to speeches, no matter how rousing, was too passive an experience to have an enduring effect. Instead Sun-tzu talked of a “death ground”—a place where an army is backed up against some geographical feature like a mountain, a river, or a forest and has no escape route. Without a way to retreat, Sun-tzu argued, an army fights with double or triple the spirit it would have on open terrain, because death is viscerally present.
