As ecological degradation continues to threaten permanent and dramatic changes for life on our planet, the question of how we can protect our imperiled Earth has become more pressing than ever before. In this book, Daniel Scheid draws on Catholic social thought as the foundation for a new type of interreligious ecological ethics, which he calls the cosmic common good, that sees humans as just a part of the greater whole of the cosmos. The cosmic common good emphasizes the instrumental and intrinsic value of nature and the integral connection between religious practice and the pursuit of the common good. Scheid begins his analysis by rooting his vision of the cosmic common good in the classical doctrines of creation found in the works of Augustine and Thomas Aquinas and in Thomas Berry's interpretation of the evolutionary cosmic story. He goes on to explore conceptions of a cosmic common good in other traditions, such as Hinduism, Buddhism, and American Indian religion. Scheid demonstrates that dialogue with these non-Christian traditions both confirms and expands the cosmic common good as a theologically authentic moral framework that re-envisions humanity's role in the universe.
