Should We Take Up the Slack?: Reflections on Non-ideal Theory in Ethics

This article asks whether (and how) our moral duties are created by others' non-compliance and whether we should fulfill them or not. For example, do we need to donate more of our income to eradicate world poverty because billionaires do not donate? If so, how much should we donate? In short, should we make up for others' defaulting on their moral duties - and if so, how and to what extent? Such situations are called non-ideal circumstances in political philosophy. With the increasing importance of non-ideal theories of justice and ethics, the question of how we should act in non-ideal situations has received more attention in the ethics literature in recent years. This article poses and addresses the question of whether we should take up the slack when others do not comply with their own moral duty. This article examines how consequentialism and contractualism might respond to non-ideal situations of taking up the slack and then defends a contractualist-constructivist approach to dealing with these situations.
