“Take your place, then. Look at what happened from every side and consider all the other ways it could have gone. Consider, even, an Africa unconquered altogether. Imagine those first Portuguese adventurers approaching the shore, spying on the jungle’s edge through their fitted brass lenses. Imagine that by some miracle of dread or reverence they lowered their spyglasses, turned, set their riggings, sailed on. Imagine all who came after doing the same. What would that Africa be now? All I can think of is the other okapi, the one they used to believe in. A unicorn that could look you in the eye.”
