Morality, it is commonly argued, cannot be extreme in the demands it makes of us, because “ought” implies “can”, and normal human psychology places limits on the extent to which most of us are capable of devoting our lives to the service of others. To evaluate this argument, we need to distinguish different uses of “ought” and “can”. Having distinguished these uses, we find that there is more than one defensible version of the principle that “ought” implies “can”. However, these distinctions can also be deployed to show that the attempt to argue from this principle to the conclusion that morality cannot be extremely demanding fails.

There can be situations in which, if I contribute to a pool of resources for helping a large number of people, the difference that my contribution makes to any of the people helped from the pool will be imperceptible at best, and maybe even non-existent. And this can be the case where it is also true that giving the same amount directly to one of the intended beneficiaries of the pool would have made a very large difference to her. Can non-contribution to the pool be morally justified on this ground? I argue that it cannot. For, first, this line of thought leaves unaffected any reasons for holding that failing to perform the direct action of benefiting someone greatly would be wrong. But the pooling system of helping people is often better than a system separating the help which is given — better because of the perceptible difference it makes to its beneficiaries. If so, failing to contribute to the pool will be at least as wrong as failing to have helped directly would have been. The paper clarifies and defends an argument of this form, showing how it can be formulated in a way that avoids apparent counterexamples, and identifying the assumptions on which it rests.

What are we morally required to do for strangers? To answer this question – a question about the scope of requirements to aid strangers – we must first answer a question about justification: why are we required to aid them (when we are)? The main paper focuses largely on answering the question about justification, but does so in order to arrive at an answer to the question about scope. Three main issues are discussed. First, to what extent should requirements of beneficence – requirements to benefit other people – be seen as generated by people’s rights to receiving aid? Secondly, what is the relationship between requirements of beneficence that apply to us collectively and requirements of beneficence that apply to each of us individually? According to Liam Murphy, our obligations to help distant strangers are fundamentally collective obligations, and any individual obligations we bear are consequently obligations to discharge our “fair share” of these collective obligations. I shall argue that, on the contrary, there are large-scale collective obligations of beneficence that derive from more fundamental individual obligations. My third issue concerns the moral significance of citizenship. What morally relevant difference is there between strangers who are compatriots and those who are not?
