I want to pause here to note a defining feature of humans, which is that we like to know why things happen, especially why really bad things happen. And if a reason is not immediately apparent, we will find one. I am reminded of a poem in Kurt Vonnegut’s novel Cat’s Cradle: Tiger got to hunt, Bird got to fly; Man got to sit and wonder, “Why, why, why?” Tiger got to sleep, Bird got to land; Man got to tell himself he understand. Vonnegut reminds us that we are both inclined toward curiosity and inclined toward arriving at some kind of comprehensible conclusion.
