Berry also contributed two introductory essays ('Economics: Its Effects on the Life Systems of the World' and 'The Earth: A New Context for Religious Unity') to the volume "Thomas Berry and the New Cosmology", in which Brian Swimme, Caroline Richards, Gregory Baum and others discuss the implications of Berry's thought for a range of disciplines and paradigms. Berry's 'Twelve Principles for Understanding the Universe and the Role of the Human in the Universe Process' offer a postscript to this 1987 work.
