You don’t need a theory of the perfect shoe to feel where your shoe pinches, and you don’t need a theory of perfect justice to grasp the injustice of the boot on your neck. We can make real headway toward a better society by spotting and rectifying the most obvious and egregious injustices. We don’t need to know what awaits on the mountain’s summit as long as we can tell the difference between “down” and “up.”
