Ecologists tell us that the interdependence of all living things makes the world more than a mechanism, more than the sum of its parts, perhaps even in some sense organically alive in its own right. But this is little more than a rediscovery in scientific terms of what had already been understood “poetically” in all previous civilizations. They may not have had (or needed) the term “ecology,” but the ancient writers were deeply aware of the inter-relatedness of the natural world, and of man as the focus or nexus of that world, which they expressed in the doctrine of correspondences. It was, of course, not scientific in its formulation, but it expressed a profound insight that remains valid, and the present ecological crisis could only have developed in a world that has forgotten it, or forgotten to live by it.
