Positive psychology is one of the biggest growth industries in the discipline of psychology. At the present time, the subfield of 'positive education' seems poised to take the world of education and teacher training by storm. In this first book-length philosophical study of positive psychology, Professor Kristjan Kristjansson subjects positive psychology's recent inroads into virtue theory and virtue education to sustained conceptual and moral scrutiny. Professor Kristjansson's interdisciplinary perspective constructively integrates insights, evidence and considerations from social science and philosophy in a way that is easily accessible to the general reader. He offers an extended critique of positive psychology generally and 'positive education' in particular, exploring the philosophical assumptions, underpinnings and implications of these academic trends in detail. This provocative book will excite anyone interested in cutting-edge research on positive psychology and on the virtues that lie at the intersection of psychology, philosophy of mind, moral philosophy, education, and daily life.
