This book analyses and discusses from a philosophical perspective the concepts of health, well-being and quality of life in contemporary biomedical research. The guiding idea of the book is that different concepts of health, well-being, and quality of life lead to different types of projects, actions and policies, both at the individual and institutional level. For this reason, it is important to analyse them and make them clear, in their interweaving of objective dimensions (the facts) and evaluative dimensions (the values).
