Moral extremists argue for highly demanding duties of beneficence on the ground that accepting a more moderate position commits us to denying the common-sense moral intuition elicited by easy rescue cases. I argue that a moderate duty of beneficence is consistent with this intuition in light of what I call aggregationism, the view that the large aggregate cost of performing many low-cost acts of beneficence is relevant to what moral agents may do in cases where they face multiple low-cost occasions to rescue. After demonstrating how the debate between moderates and extremists turns on the truth of aggregationism, I defend aggregationism against the challenge that it is inconsistent with respecting the separateness of persons.

Moral extremists argue for a demanding duty of poverty relief by leveraging powerful intuitions about our duties to rescue those close at hand. I clear the way for a less demanding duty by arguing that this argumentative strategy commits the extremist to a conception of our duty in the face of global poverty that is deeply at odds with our convictions about how we may discharge that duty. These convictions reveal that global poverty and easy rescue cases give rise to duties of different kinds: whereas duties of rescue are ultimately explicable by appeal to moral claims to assistance, duties of poverty relief are not. The extremist’s most compelling argumentative strategy is therefore not viable—he may not straightforwardly appeal to facts about the demandingness of duties of rescue in arguing for demanding duties of poverty relief.
