This book draws on the feminist critique of reason to argue that the master form of rationality of western culture has been systematically unable to acknowledge dependency on nature, the sphere of those it has defined as 'inferior' others. Because its knowledge of the world is systematically distorted by the elite domination which has shaped it, the master rationality has developed 'blind spots' which may threaten our survival. The future depends increasingly on our ability to create a truly democratic and ecological culture beyond dualism.
