In the encyclical Laudato Si’: On Care for Our Common Home, Pope Francis offered a compelling moral vision for personal and ecological renewal, as well as a sweeping critique of dominant forms of consumerism (at the personal level) and cost-benefit analysis (at the level of firms and governments). Like Laudato Si itself, the essays in this volume take a dialectical approach to the concrete and the abstract, the particular and the universal, the immediate and the long-term, the material and the spiritual. First, on the level of policy, they address how the explicit program for conservation of land, air, and water in Laudato Si either coheres with or challenges existing environmental programs. Second, at a higher level of abstraction, they examine how Laudato Si invites readers to adopt a new, more capacious normative framework for addressing environmental policy concerns.
