This book provides a short immersion to the subject of happiness by examining the scholarly literature on it. Among the questions it explores are: What is the meaning of happiness? Is it something that it is possible to understand in general terms, perhaps by distinguishing between different meanings of it, or is it something that is best left to people to define for themselves as they seek to be happy in their own way? Can happiness and its different meanings be measured and, if so, how? On what does happiness depend? Does a person's happiness depend on his or her disposition and individual circumstances, or does it depend in part on how society is organized and on what the government does? Does money buy happiness? What kinds of political, economic, social and environmental factors make people and societies happier? What can people do, either individually or collectively, to become happier?
