[I]t is impossible to empathize with seven billion strangers, or to feel toward someone you’ve never met the degree of concern you feel for a child, a friend, or a lover. Our best hope for the future is not to get people to think of all humanity as family—that’s impossible. It lies, instead, in an appreciation of the fact that, even if we don’t empathize with distant strangers, their lives have the same value as the lives of those we love.
