Introduction"This book is not about the principles of justice, but about the constituents of the good life. (...) What is the good life? What is it not? And what changes in our moral and economic system would be needed to realize it? (...) Our book brings together the perspectives of philosophy and economics in the conviction that the two disciplines need each other, the one for the sake of its practical influence, the other for the sake of its ethical imagination. It aims to revive the old idea of economics as a moral science; a science of human beings in communities, not of interacting robots."
