Abstract
In this article, I argue that Powers and Faden’s non-ideal, comprehensive theory of justice cannot keep in line with the proposed moderateness of their essentialist approach. My argument is as follows: Powers and Faden’s comprehensive theory of justice contravenes the thrust of moderate essentialism, in claiming that their theory values health for its own sake. Why do they define their conception of justice as valuing health for its own sake when it is likely to be incongruous with their essentialist approach? To understand this, we should examine their sufficientarian proposal. There are two requirements for plausible sufficientarianism. The first requirement is to specify the threshold below which people are seriously deprived and must be urgently benefited in a non-arbitrary manner. The second requirement is that sufficientarianism should be sensitive to certain inequalities above the threshold. Powers and Faden’s approach convincingly meets the first requirement. However, the non-ideal aspect of their approach, which is key to meeting the second requirement, makes it explicit that at least one of the listed dimensions of well-being must be valued for their own sake. This is not reconcilable with their own characterization of moderate essentialism. For this reason, we should conclude that Powers and Faden fail to argue for moderate essentialism
