Integral Ecology as a Call to Responsibility: Approximations Between Hans Jonas and Pope Francis

This article aims to examine the concept of responsibility through the lens of the “integral ecology” proposed by Pope Francis in Laudato Si’. The objective is to demonstrate how the ethics of responsibility developed by Hans Jonas in his seminal 1979 work aligns with Pope Francis’s concerns and simultaneously offers a complementary theoretical–philosophical framework. To this end, we begin by showing how responsibility occupies a central place in the papal encyclical, assuming a multidimensional perspective. From there, we analyze how the understanding of responsibility transitions from ontology (Jonas) and anthropology (Francis) to ethics, taking the biosphere as a new object of responsibility in light of the threats posed by the unchecked advance of technological powers against nature. This investigation is based on a comparative and conceptual analysis of primary texts by Hans Jonas and Pope Francis. This shift also entails the recognition of nature’s intrinsic rights and an understanding of species extinction as both an impoverishment (Jonas) and a mutilation (Francis) of creation. We conclude by demonstrating how the call for integral ecology becomes an urgent task for the present generations in the context of catastrophe prevention. In this way, integral ecology attains its radical meaning when understood as demanding two fundamental transformations: a change in consciousness and a change in lifestyle—from consumerism to frugality.
