How Wonder Works
When I was growing up in New York City, a high point of my calendar was the annual arrival of the Ringling Brothers and Barnum & Bailey Circus — ‘the greatest show on earth’. My parents endured the green-haired clowns, sequinned acrobats and festooned elephants as a kind of garish pageantry. For me, though, it was a spectacular interruption of humdrum reality – a world of wonder, in that trite but telling phrase.
Wonder is sometimes said to be a childish emotion, one that we grow out of. But that is surely wrong. As adults, we might experience it when gaping at grand vistas. I was dumbstruck when I first saw a sunset over the Serengeti. We also experience wonder when we discover extraordinary facts. I was enthralled to learn that, when arranged in a line, the neurons in a human brain would stretch the 700 miles from London to Berlin. But why? What purpose could this wide-eyed, slack-jawed feeling serve? It’s difficult to determine the biological function of any affect, but whatever it evolved for (and I’ll come to that), wonder might be humanity’s most important emotion.
