Something is profoundly wrong with the way we live today. For thirty years we have made a virtue out of the pursuit of material self-interest: indeed, this very pursuit now constitutes whatever remains of our sense of shared purpose. But we have forgotten how to think about the life we live together: its goals and purposes. We are now not only post-ideological; we have become post-ethical. We have lost touch with the old questions that have defined politics since the Greeks: is it good? Is it fair? Is it just? Is it right? Will it help bring about a better society? A better world? The social contract that defined postwar life in Europe and America - the guarantee of security, stability and fairness - is no longer assured; in fact, it's no longer part of collective conversation.
