The capabilities approach and Catholic social teaching: an engagement

This essay brings Martha Nussbaum's politically liberal version of the Capabilities Approach (CA) to human development into critical dialogue with the Catholic Social Tradition (CST). Like CST, Nussbaum's focus on embodiment, dependence and dignity entails a social use of property which privileges marginalized people, and both theories explain the underdevelopment of central human capabilities in social rather than exclusively material terms. Whereas CST is metaphysically and theologically ‘thick', however, CA is ‘thin’: its proponents positively eschew metaphysical commitments, believing a commitment to quasi-Rawlsian ‘overlapping consensus' is more consistent with political liberalism. This creates two tensions between CA and CST. The first is that CST understands the internal virtues of essentially social practices to be inseparable from their concrete instantiation in actual communities, while CA sometimes describes these virtues as political entitlements which can be supported independently of the comprehensive doctrines of particular communities. We argue, therefore, that CA's commitment to political liberalism tends to ‘crowd out’ particular conceptions of the good, such as those found in CST. Second, because CST recognizes a plurality of spiritual purposes of property that CA does not, including promotion of what Pope Benedict XVI calls the ‘logic of gift', from the perspective of CST, CA will tend to be motivationally deficient in ways that negatively impact human development.
