Animals and Kingdom of Ends

The abandonment of Teleological Anthropocentrism does not alter the plain fact that many parts of Nature are life-supporting, with the apparent primary beneficiary still Humanity, but with little evidence of reciprocity.  Thus, though collapsing the traditional Human-Animal dualism, as a potential foundation for an Ecology, Spinoza's Naturalism remains limited.  In contrast, probably the greater influence on the concept of Animal Rights is Kant's Super-Natural model--his Kingdom of Ends, on the basis of which the treatment of animals as mere means is prohibited.  But, the model remains heuristic, in contrast with which a robust Ecology would explicate how Humanity natively serves a life-supporting function in a system of Nature.
