Since the earliest days of philosophy, thinkers have debated the meaning of the term happiness and the nature of the good life. But it is only in recent years that the study of happiness—or “hedonics”—has developed into a formal field of inquiry, cutting across a broad range of disciplines and offering insights into a variety of crucial questions of law and public policy. This book brings together the best and most influential thinkers in the field to explore the question of what makes up happiness—and what factors can be demonstrated to increase or decrease it. The book offers an account of the way that hedonics can productively be applied to psychology. It also considers the unexpected relationship between happiness and health problems. It further views hedonics through the lens of cost–benefit analysis, another chapter considers the relationship between happiness and taxation, and the book also examines the role crime—and fear of crime—can play in people's assessment of their happiness, and much more.
