" Empathy isn’t just something that happens to us—a meteor shower of synapses firing across the brain—it’s also a choice we make: to pay attention, to extend ourselves. It’s made of exertion, that dowdier cousin of impulse. Sometimes we care for another because we know we should, or because it’s asked for, but this doesn’t make our caring hollow. The act of choosing simply means we’ve committed ourselves to a set of behaviors greater than the sum of our individual inclinations: I will listen to his sadness, even when I’m deep in my own. To say “going through the motions”—this isn’t reduction so much as acknowledgment of the effort—the labor, the motions, the dance—of getting inside another person’s state of heart or mind. "
