Utilitarianism could still be a viable moral and political theory, although an emphasis on justice as distributing burdens and benefits has hidden this from current conversations. The traditional counterexamples prove that we have good grounds for rejecting classical, aggregative forms of consequentialism. A nonaggregative, liberal form of utilitarianism is immune to this rejection. The cost is that it cannot adjudicate when the basic needs of individuals or groups are in conflict. Cases like this must be solved by other methods. This is not a weakness in liberal utilitarianism, on the contrary. The theory clarifies what we should admit to begin with: that ethical doctrines do not have universally acceptable solutions to all difficult problems or hard cases. The theory also reminds us that not all problems are in this sense difficult or cases hard. We could alleviate the plight of nonhuman animals by reducing meat eating. We could mitigate climate change and its detrimental effects by choosing better ways of living. These would imply that most people's desire satisfaction would be partly frustrated, but liberal utilitarianism holds that this would be justified by the satisfaction of the basic needs of other people and nonhuman animals.
功利主义仍然可以成为一种可行的道德和政治理论,尽管强调正义是分配负担和利益,这使得当前的讨论掩盖了这一点。传统的反例证明,我们有充分的理由拒绝经典的、加总的后果主义形式。一种非加总的、自由的功利主义形式可以免受这种反驳。代价是,当个人或群体的基本需求发生冲突时,它无法进行裁决。这种情况下必须通过其他方法解决。这不是自由功利主义的弱点,相反,该理论阐明了我们首先应该承认的:伦理学说没有普遍接受的解决方案来解决所有困难问题或棘手情况。该理论还提醒我们,并非所有问题在这个意义上都是困难的或棘手的。我们可以通过减少肉食来缓解非人类动物的困境。我们可以通过选择更好的生活方式来减轻气候变化及其不利影响。这将意味着大多数人的欲望满足将在一定程度上受挫,但自由功利主义认为,这将通过满足其他人以及非人类动物的基本需求来证明是合理的。
