It appears to have been established that it is not possible for us to harm distant future generations by failing to adopt long-range welfare policies which would conserve resources or limit pollution. By exploring a number of possible worlds, the present article shows, first, that the argument appears to be at least as telling against Aristotelian, rights-based and Rawlsian approaches as it seems to be against utilitarianism, but second, and most importantly, that it only holds if we fail to view (...) moral agents as individuals. The article also concludes that the argument has profoundly counter-intuitive implications. (shrink)

Alan Carter correctly argues that Thomas Schwartz's ‘future persons paradox’ applies with equal force to utilitarianism, rights theory and Aristotelian ethics. His criticism of Rawls's ‘justice between generations’ is less successful, because of his failure (and perhaps Rawls's as well) to fully appreciate the hypothetical nature of the ‘original position’. Carter's attempt to refute Schwartz's argument by focusing on the individuality of moral action fails, since it evades the essential point of Schwartz's argument. The best response to Schwartz is to (...) concede the essential validity of his argument and then to turn that argument into an ad absurdum refutation of his central premise, ‘the person affecting principle’.

Ascertaining the optimum global population raises not just substantive moral problems but also philosophical ones, too. In particular, serious problems arise for utilitarianism. For example, should one attempt to bring about the greatest total happiness or the highest level of average happiness? This article argues that neither approach on its own provides a satisfactory answer, and nor do rights-based or Rawlsian approaches, either. Instead, what is required is a multidimensional approach to moral questions—one which recognises the plurality of our values. (...) Such an approach can be formalised by employing multidimensional indifference-curves. Moreover, whereas classical utilitarianism might be thought to enjoin us to bring about a larger global population, a multidimensional approach clearly suggests a significant reduction in human numbers.
