The status of Marxism has always been a contested issue among Green political theorists, many of whom have expended much energy criticizing the canons of scientific socialism and the growth-dependent politics of the labor movement. Yet surprisingly little attention has been directed to exploring in detail the contribution of more contemporary currents of Western Marxism, most of which reject orthodox Marxism and many of which have foreshadowed important aspects of the Green critique of scientism, industrialism, and modernity. In this article, I undertake such a task by critically exploring the compatibility between Green political philosophy and the Critical Theory of Jfirgen Habermas. This critique is conducted from the perspective of the more radical, ecocentric wing of the emergent Green political spectrum. One of the hallmarks of this ecocentric stream of Green political thought is that it seeks to widen in space and time the class of beings whose interests are taken into account in political decision-making to include not only future generations but also the nonhuman community) According to this perspective, the ecological crisis is not simply a crisis of human democratic participation, welfare, and survival; the now familiar litany of ecological disturbances, particularly the alarming rate of species extinction, reflects a crisis of evolutionary proportions affecting all members of the biotic community. A central argument of ecocentric theorists is that unless we move from an anthropocentric (or humancentered) to an ecocentric (or earth-centered) conception of our place in the evolutionary drama then we will not only impoverish our own life-world but also see to the extinction of countless other species. As Michael Zimmerman has neatly put it, "If... [humanity] is understood as the goal of history, the source of all value, the pinnacle of evolution, and so forth, then it is not difficult for humans to justify the plundering of the natural world, which is not human and therefore valueless "'2
