The three main non-traditional schools of environmental philosophy - social ecology, feminism and deep ecology - contain divergent views of and claims regarding the universalization of their particular world views. One example of this divergence of views concerns the status of human/non-human relationships. Like many other contemporary non-traditional liberation movements and theories, these three environmental movements and schools of thought have been influenced by the theories of Karl Marx. Therefore, in order to clarify and understand the way in which, and (...) the extent to which, key proponents of each of these environmental movements and philosophies universalize their particular philosophic world views, this thesis compares their theories to those of Karl Marx. Emphasis is placed on Marx's critique of abstract and idealist-based universalizing as applied in the area of human-non-human relationships, as this critique and area of application is a key feature of non-traditional environmental thought. Also, the methodology used in this thesis is a critical analysis of the primary philosophic texts and related commentaries. (shrink)
