Saleem Ali discusses his sweeping, globally integrative new book, Earthly Order: How Natural Laws Define Human Life. Earthly Order explores patterns of deep structural linkages between natural order and human-constructed order, between the environment and society; it shows how natural laws operate at all levels of the majestic hierarchy of human existents, from the quantum chemistry of our bodies, to sustainability cycles of our planet, to economic, social, and political structures of our societies.
