The first part of this article offers a systemic comparison of Pope Francis’s “integral ecology” with the “technocratic paradigm.” The second part is devoted to an internal critique of the paradigm: (i) the primacy accorded instrumental causality in a “disenchanted world,” (ii) the technical reduction of prudence, and (iii) the consequent fragmentation of ethical systems. The critique supports key aspects of Francis’s ecological ethics: the option for the poor, intergenerational responsibility, and recognition of the intrinsic value of nonhuman nature. The third part shows how such an internal critique underwrites the uses of religious rhetoric in public reasoning: the re-enchantment of the world.
