“The leopard in the zoo wanders to the edge of his pen and, through the bars or across an unjumpable moat, he stares at you with contempt for your inferiority, for needing that barrier between you. There is a shared understanding in that moment, nonverbal but no less real: the leopard is predator and you are prey, and it is only the barrier that permits us humans to feel superior and secure. That feeling, standing at the leopard’s cage, is edged with shame, at the animal’s superior strength, at his hauteur, his low estimation of you.”
