Do I think it was inherent nobility that brought us out here?” He shook his head. “Maybe. I don’t call it nobility, though. I think it’s our innate human need to champion the underdog. We are constant optimists. We’re the emotional descendents of the caveman who stood defiant in the front of the wooly mammoth. We rebuild cities at the base of Vesuvius, get back on the bicycle when we fall off, whack that hornet’s nest every spring. Humans cheer for the couldn’t be, believe in the shouldn’t be. We love causes; the harder, the more lost they are, the more we love them. Is that nobility?Maybe. Maybe it’s a pernicious genetic defect that makes our species susceptible to shared delusion. Whatever it is, it keeps life interesting.
