> DSM-5 seems to have no definition of happiness other than the absence of suffering. The normal individual in this book is tranquilized and bovine-eyed, mutely accepting everything in a sometimes painful world without ever feeling much in the way of anything about it.
Positive psychology[1] is a branch of psychology that agrees with this critique, and rather than looking at what goes wrong with people, it looks at what is right about people. There is a book "Character Strengths and Virtues"[2] that is aimed at being the positive counterpart to the DSM, providing a taxonomy of character strengths that have been identified across different times and cultures.
