If we cared sufficiently about effects on others, and changed our moral view, we would solve such problems. It is not enough to ask, ‘Will my act harm other people?’ Even if the answer is No, my act may still be wrong, because of its effects. The effects that it will have when it is considered on its own may not be its only relevant effects. I should ask, ‘Will my act be one of a set of acts that will together harm other people?’ The answer may be Yes. And the harm to others may be great.
