Many people and countries are now beginning to evaluate the success of their lives or society not purely in terms of money or gross domestic product. The currency of traditional economics - preference satisfaction - has fallen into question as an ethical value. The global financial crisis is seen by many as a failure of capitalism. Some countries have proposed a Gross Happiness Index to replace GDP as the measure of the productivity of a country. What is of intrinsic value in human lives? How should we measure how good a human being's life is? What is happiness and what constitutes well-being? What can we learn from religion, philosophy, economics and the cognitive sciences about happiness and well-being? Are happiness and well-being relative to culture? What roles do pleasure and happiness play in ethics? Should we aim to maximise happiness and pleasure? How should the views of people with disability be incorporated into an ethics of well-being? Jointly organised by The Uehiro Foundation on Ethics and Education (Tokyo), The Carnegie Council for Ethics in International Affairs (New York) and Oxford Uehiro Centre for Practical Ethics (University of Oxford) this conference will seek to understand the nature and value of happiness and well-being in practical ethics.
