Principles of sufficiency are widely discussed in debates about distributive ethics. However, critics have argued that sufficiency principles are vulnerable to important objections. This paper seeks to clarify the main claims of sufficiency principles and to examine whether they have something distinctive and plausible to offer. The paper argues that sufficiency principles must claim that we have weighty reasons to secure enough and that once enough is secured the nature of our reasons to secure further benefits shifts. Having characterized sufficientarianism (...) in this way, the paper shows that the main objections to the view can be avoided; that we can examine the plausibility of sufficiency principles by appealing to certain reasons that support a shift; and that we should be optimistic about the prospects for sufficientarianism because many of our strongest reasons seem to be of this sort. This shift, I claim, is the overlooked grain of truth in sufficientarianism. (shrink)

Equality of Opportunity is widely thought of as the normative ideal most relevant to the design of educational institutions. One widely discussed interpretation of this ideal is Rawls' principle of Fair Equality of Opportunity. In this paper I argue that theories, like Rawls, that give priority to the achievement of individual autonomy, are committed to giving that same priority to a principle of sufficient opportunity. Thus, the Rawlsian's primary focus when designing educational institutions should be on sufficiency and not equality. (...) The paper then argues this commitment has at least three attractive implications. Firstly, it enables defenders of Fair Equality of Opportunity to overcome Richard Arneson's powerful objections. Secondly, it suggests a revised version of the principle of Fair Equality of Opportunity that is more plausible. Thirdly, it has attractive practical implications for educational provision. (shrink)

Common sense morality and legislations around the world ascribe normative relevance to biological connections between parents and children. Procreators who meet a modest standard of parental competence are believed to have a right to rear the children they brought into the world. I explore various attempts to justify this belief and find most of these attempts lacking. I distinguish between two kinds of biological connections between parents and children: the genetic link and the gestational link. I argue that the second (...) can better justify a right to rear.
