John Dunn's Western Political Theory in the Face of the Future demonstrates that the major traditions of thought from which the political values of the modern West have emerged are all, in the light of recent world history, in crucial respects incoherent or flawed. This second edition underlines the drastic changes in the challenges which face the world, in the wake of the Soviet Union's collapse and the end of the Cold War, stressing the ever tighter linking of the global economy with the ecology in which we live, and the problems which this poses for the survival of civilisation.
