The main thing is being happy? Anyone involved either theoretically or practically in the upbringing and education of young people is, even if only unconsciously, trying to make them happy. Accordingly, happiness was an obvious and explicit goal of education in the early days of the field as an academic discipline. Today, surprisingly, there is little mention of it. That is the starting point for this book: beginning with views of happiness in antiquity, it traces educational reflections on happiness from the Enlightenment to the present day. It then inquires into possible reasons for the current marginalization of the topic. The book concludes with an invitation to give greater consideration again to the complexity of the topic of happiness in education & even though there is no educational action that is ultimately capable of guaranteeing happiness.
