  Agent-relativity is also supposed to solve other problems. W. D. Ross (1930, 34–35) argued that, if breaking a promise created only slightly more happiness overall than keeping the promise, then the agent morally ought to break the promise according to classic utilitarianism. This supposed counterexample cannot be avoided simply by claiming that keeping promises has agent-neutral value, since keeping one promise might prevent someone else from keeping another promise. Still, agent-relative consequentialists can respond that keeping a promise has great value from the perspective of the agent who made the promise and chooses whether or not to keep it, so the world where a promise is kept is better from the agent’s perspective than another world where the promise is not kept, unless enough other values override the value of keeping the promise. In this way, agent-relative consequentialists can explain why agents morally ought not to break their promises in just the kind of case that Ross raised.
