This volume brings into conversation two major moral traditions in the social sciences and humanities that offer common areas for understanding, interpreting, and transforming the world. Over the last decade, moral theologians who work on issues of poverty, social justice, human rights, and political institutions have been finding inspiration in the capability approach (CA). Conversely, social scientists who have been working on issues of poverty and social justice from a CA perspective have been finding elements in the Catholic social tradition (CST) to overcome some of the limitations of the CA, such as its vagueness regarding what counts as a valuable human life and its strong individual focus. Integral Human Development brings together for the first time social scientists and theologians in dialogue over their respective uses of CST and CA. The contributors discuss what their mutual grounds are, where they diverge, and where common areas of collaboration and transformative action can be found. The contributors offer a critical analysis of CA from the perspective of theology. They also provide an original account of CST. The book offers a broader historical, biblical, social, economic, political, and ecological understanding of CST than that which is currently available in the CST literature. The book will interest students and practitioners in global affairs, development studies, or the social sciences who seek to better understand the Catholic tradition and its social teachings and what they can offer to address current socio-environmental challenges.
