The argument from relevance expresses an intuition that, although shared by many applied ethicists, has not been analyzed and systematized in the form of a clear argument thus far. This paper does this by introducing the concept of value relevance, which has been used before in economy but not in the philosophical literature. The paper explains how value relevance is different from moral relevance, and distinguishes between direct and indirect ways in which the latter can depend on the former. These (...) clarifications allow the argument to explain in detail how we can make two claims. The first one is that being a recipient of value should be the only criterion for full moral considerability. This follows if we accept that value relevance should determine, directly or indirectly, moral relevance. The second claim is that, given what the main theories of wellbeing imply regarding what entities can be recipients of value, sentience is both a sufficient and a necessary criterion for full moral considerability. The paper argues that this conclusion stands even if we hold views that consider other values different from sentience. (shrink)

Although the sufficientarian approach to distributive justice is increasingly popular in contemporary political philosophy, it is not easy to give an appropriate formulation of sufficientarianism. In this article, I aim to show that a proper formulation of sufficientarianism should satisfy three conditions: the Distinctiveness condition, the Intermediacy condition, and the Universality condition. However, I argue that it is very difficult to propose a substantial account of sufficiency that can satisfy the three conditions altogether. After examining several influential sufficientarian accounts, I (...) contend that none of them can satisfy the three conditions on sufficientarianism. (shrink)

This article analyses the concept of sufficiency in relation to sustainability and discusses ethical implications for sustainable organisation in time and place. We identify three foundational conceptualisations of sufficiency related to sustainability: (1) a limits model that starts with objective boundaries imposed by the biosphere and basic human needs; (2) a preference model that treats sufficiency as a subjective inclination for moderation defined situationally; and (3) a balancing model that seeks to integrate the objective limits and subjective preferences by focussing (...) on action embedded in the socio-ecological context. This includes balancing the needs of humans with those of non-humans. The limits model builds on universal duty, the preference model on preference utilitarianism and the balancing model on action-oriented virtue ethics. The balancing model of sufficiency is well suited to meeting the needs of present and future generations as well as delivering intra- and inter-generational justice not limited to humans. (shrink)

This article asks about the justification for the principle of political equality in the sense of equal entitlement to basic rights. A preliminary portion criticizes standard justifications that refer to a property or properties all human beings share; these fail because they are untrue, irrelevant, or question-begging. The more substantial and constructive portion of the article then argues for a different, indirect mode of justification, based on rebuttals of historical presumptions of inequality and the actual evolution of the idea of (...) equality through partial steps and specific precedents. The justification of political equality is thus connected to the explanation of its emergence. (shrink)
