Derek Parfit presents his Mere Addition Paradox in order to demonstrate that it is extremely difficult to avoid the Repugnant Conclusion. And in order to avoid it, Parfit has embraced perfectionism. However, Stuart Rachels and Larry Temkin, taking their lead from Parfit, have concluded, instead, that the Repugnant Conclusion can be avoided by denying the axiom of transitivity with respect to the all-things-considered-better-than relation. But this seems to present a major challenge to how we evaluate normatively. In this article I show how the Mere Addition Paradox and the Repugnant Conclusion can both be avoided without subscribing to perfectionism, and without sacrificing the axiom of transitivity.

This article considers two different, yet related, theoretical approaches that could be employed to ground the anarchist critique of Marxist-Leninist revolutionary practice, and thus of the state in general: the State-Primacy Theory and the Quadruplex Theory. The State-Primacy Theory appears to be consistent with several of Bakunin's claims about the state. However, the Quadruplex Theory might, in fact, turn out to be no less consistent with Bakunin's claims than the State-Primacy Theory. In addition, the Quadruplex Theory seems no less capable of supporting the anarchist critique of Marxism-Leninism than the State-Primacy Theory. The article concludes by considering two possible refinements that might be made to the Quadruplex Theory.

As Rawls's thought evolved from his 1958 article ‘Justice as Fairness’ to the 1996 edition of his book Political Liberalism, his response to the problem of political compliance would seem to have undergone a number of changes. This article critically evaluates the development of Rawls's various explicit or implied arguments that serve to justify compliance to just social arrangements, and concludes that the problem of political compliance remains without any cogent solution within the vast corpus of Rawls's work.

Michael Tooley defends infanticide by analysing ‘A has a right to X’ as roughly synonymous with ‘If A desires X, then others are under a prima facie obligation to refrain from actions that would deprive him [or her] of it.’ An infant who cannot conceive of himself or herself as a continuing subject of experiences cannot desire to continue existing. Hence, on Tooley’s analysis, killing the infant is not impermissible, for it does not go against any of the infant’s desires. However, Tooley’s argument in support of his analysis seems to justify, instead, a slightly more subtle analysis—namely, ‘A has a right to X’ is roughly extensionally equivalent with ‘Unless A expresses his or her desire that not‐X, then others are under a prima facie obligation to refrain from actions that would deprive him or her of X.’ But given this analysis, the infant’s purported lack of any capacity to conceive of himself or herself as a continuing subject of experiences implies that we cannot be released from any duty that we might have not to harm him or her. In short, Tooley’s argument in support of his analysis actually implies that infanticide may well be impermissible.

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.

Andrew Dobson has outlined three conceptions of environmental sustainability: the ‘critical natural capital’ conception; the ‘irreversibility’ conception; and the ‘natural value’ conception. He has also attempted to map out the various ‘dimensions of social justice’– his purpose in so doing being to analyze the ‘encounter’ of each conception of environmental sustainability with the points on his map. Not surprisingly, Dobson concludes that as one moves from the ‘critical natural capital’ conception through the ‘irreversibility’ conception to the ‘natural value’ conception of ‘sustainability’, the ‘points of contact’ with his map of ‘the dimensions of social justice’ are found to ‘become fewer and further apart’. In this article I argue that Dobson is fundamentally confused in his reason for thinking why this is so. I also argue that a core argument he deploys concerning future generations cannot do the work he requires of it.
