Many philosophers argue that reasonably well-off people have very demanding moral obligations to assist those living in dire poverty. I explore the relevance of demandingness to determining moral obligation, challenging the view that “morality demands what it demands” and that if we cannot live up to its demands that’s our problem, not morality’s. I argue that not only for practical reasons but also for moral-theoretical ones, the language of duty, obligation, and requirement may not be well-suited to express the nature of our responsibilities in these matters. But it is nevertheless morally imperative to reduce global poverty and inequality. Distinguishing between the Ought of states of affairs and the Ought of moral obligation, I defend an approach that looks to institutions to alter the environment within which people make choices and that employs our understanding of human psychology to encourage changes in behavior.

Debate about the responsibilities of affluent people to act to lessen global poverty has dominated ethics and political philosophy for forty years. But the controversy has reached an impasse, with the main approaches either demanding too much of ordinary mortals or else letting them off the hook. In Distant Strangers I show how a preoccupation with standard moral theories and with the concepts of duty and obligation have led philosophers astray. I argue that there are serious limits to what can be demanded of ordinary human beings, but that this does not mean we must abandon the moral imperative to reduce poverty. Drawing on findings from behavioral economics and psychology, I show how we can motivate better-off people to lessen poverty without excessively taxing their moral virtue. And I argue that this approach is not just pragmatically but morally appropriate.
