Pragmatism asks us to be moral referees, watching the action unfold and determining whether there is any difference between one outcome and another—and thus whether the dispute is idle or meaningful. Of course, if we’re playing referee, a new question arises: When do we blow the whistle? If someone does something bad, something that we believe has a tangibly negative effect on the world, should we say so? When, if ever, should we not only determine that someone is acting immorally, but actually call them on it?
