This essay begins by describing T.M. Scanlon’s contractualism according to which an action is right when it is authorised by the moral principles no one could reasonably reject. This view has argued to have implausible consequences with regards to how different-sized groups, non-human animals, and cognitively limited human beings should be treated. It has also been accused of being theoretically redundant and unable to vindicate the so-called deontic distinctions. I then distinguish between the general contractualist framework and Scanlon’s version of (...) contractualism. I explain how the general framework enables us to formulate many other versions of contractualism some of which can already be found in the literature. Understanding contractualism in this new way enables us both to understand the structural similarities and differences between different versions of contractualism and also to see the different objections to contractualism as internal debates about which version of contractualism is correct.

According to the procreation asymmetry, we have strong pro tanto reason to do what prevents someone from coming into a miserable existence—an existence so bad that it would be rational to prefer having never been born—solely because it prevents them from coming into a miserable existence, but we do not have strong pro tanto reason to do what allows someone to come into a happy existence solely because it allows them to come into a happy existence. At best, the fact (...) that an act would create a happy person merely offsets the reasons we have to avoid that act—i.e., an act that would be impermissible because it brings a miserable person into existence could be rendered permissible if it also brought into existence enough happy people. In this paper, I first argue that there is an intuitive asymmetry in the offsetting weight of happy humans and the offsetting weight of happy animals: the offsetting weight of happy animal lives vis-à-vis miserable animal lives appears to be greater than the offsetting weight of happy human lives vis-à-vis miserable human lives. This is the Procreation Asymmetry Asymmetry. I then argue that there is no Procreation Asymmetry Asymmetry. The best explanation of why happy human lives have only weak offsetting weight implies that happy animal lives also have only weak offsetting weight. (shrink)

This thesis focuses on what I call the question of exclusion. This question, I argue, is one that poses serious challenges to social contract approaches to justice and political legitimacy. In an intuitive way, the exclusion of some individuals seems to be a corollary of the social contractualist approach, which ascribes justice or legitimacy to a social arrangement insofar as it can be regarded as the product of the (actual – expressed or tacit – or hypothetical) consent of specified parties. (...) Consequently, this approach excludes those whose consent is not required in order to view an arrangement as legitimate or just. Given the enormous and continuing influence of John Rawls’s social contract theory, I take the Rawlsian view as my primary focus, concentrating on the way in which the question of exclusion raises challenges for Rawlsian contractualism. According to Rawls’s theory, those who participate in the hypothetical contract and to whom political power ought to be justifiable are reasonable and rational. They are reasonable in the sense that they understand and are willing to comply with the requirements of justice and they are rational in that they have the capacity to form, revise, and pursue a conception of the good. This gives rise to two categories of exclusion. In the first part of the thesis, I examine the exclusion of those who will develop the two moral powers sufficiently only if those who are represented in the social contract act (or refrain from acting) in certain ways. This category includes children, foetuses, and unreasonable citizens. Intuitively, justice issues in requirements in at least some of these cases, but it is hard to make sense of this on the Rawlsian approach. In the second part of the thesis, I address the question of exclusion regarding those who will never develop the two moral powers to the requisite degree, such as individuals with severe cognitive disabilities and non-human animals. Again, intuitively, justice issues in requirements here, but their justification is not clear on the contractualist approach. My conclusion is threefold. First, I argue that the problems the question of exclusion poses cannot be addressed by a single solution. Second, I safeguard Rawlsian contractualism by showing how each problem can be resolved. Third, I offer policy-prescriptions on a number of issues, such as education, abortion, and the criminal justice system. (shrink)

In Justice as Impartiality Brian Barry seeks to present ‘a universally valid case in favour of liberal egalitarian principles’. It is an ambitious enterprise undertaken with originality, vigour, and wit; and containing a wealth of interesting argumentation. If, ultimately, Barry fails in the task he sets himself, as I shall argue he does, the attempt is none the less highly instructive; not only because of the many local successes in his arguments with proponents of alternative theories and his often illuminating (...) discussions of particular issues, but also because of the lessons to be learnt from his failure. For if even Barry's formidable defence of a contractualist, neutralist liberalism does not succeed then there may be good reason to think that none will. While this larger claim will not be fully justified here, and the case against justice as impartiality does not depend upon it, one of my deeper motivating concerns is to try to show that the most important failures in Barry's argument are inextricably bound up with the nature of his undertaking. We are concerned, I believe, not just with some inevitable imperfections of execution but with a flawed project. (shrink)
