The existence of global poverty is uncontroversial. None would deny that there are people in this world who suffer not only relative but absolute deprivation.Recognizing this fact forces those of us who live relatively affluent lives in relatively affluent countries to consider what obligations we have to improve the lot of impoverished people around the world. Those who reject the view that we have extensive obligations to distant strangers often appeal to a distinction between negative and positive duties. Negative duties, we can imagine them saying, are duties not to harm others. They are willing to concede that such duties are stringent, which is to say that they are not easily overridden, but they assert that duties not to harm cannot ground a general obligation to the global poor.Instead, they see any such general obligation as necessarily grounded in positive duties, or duties to help. On one version of the argument, these positive duties are not properly considered duties at all. Helping is instead at most supererogatory and never required. On another version, positive duties count as genuine duties, but are seen as far less stringent than negative duties and therefore more easily overridden. Purported obligations to provide assistance to distant strangers suffering from poverty turn out to be particularly weak, or so it is claimed, because they are properly subordinated to a host of positive duties of assistance to family, friends, community members and fellow citizens, as well as a permission to give special consideration to one's own interests and projects.There are several ways to resist this line of argument. To begin with, one might reject the distinction between negative and positive duties as conceptually confused. One might, for instance, argue that not helping just is a form of harming, which would be to deny that we can even distinguish between
