Divergent beliefs about humanitys relationship to nature collide as the second millenium ends. One belief emphasizes that a distinctive characteristic of humansreasonenables them to reshape and master nature. Another insists that nature is not so plastic, hence humans must adapt to nature and render development sustainable, or even limit growth. Social ecology asserts that environmental problems result from institutional hierarchies and suggests decentralized institutions and egalitarian ethics. According to deep ecology such problems originate in cultures assuming only humans are worthwhile, thus it stresses the intrinsic value of nature. Feminists are torn between values based on the equality of men and women and ecofeminist values postulating that women are inherently closer to nature than men. Rationality and Nature critically assesses these conflicting cultural tendencies. Waste has been the forgotten element of political economy. Western society has sophisticated methods of financial accounting but does little to account for the lossesfinancial and humanof waste. Raymond Murphy proposes in this book a theory of environmental debt as a source of capital accumulation. He develops a model of environmental classes that helps us to understand the political and economic basis of conflict over the environment. Environmental degradation did not occur on a vast scale until science and applied science were developed. Are they responsible for it and can they be reoriented toward a more symbiotic relationship with nature? Other ways of bringing about a symbiotic relationship are also explored in this book: compulsion, ecological values, ecological experience, and ecological knowledge.
