How do societies go through major technological, economic and structural changes peacefully? The Nordic Secret explores how Denmark, Norway and Sweden went from poor feudal agricultural societies to rich industrialized democracies thanks to the German educational concept of Bildung. The book also investigates the close relationship between Bildung and contemporary developmental psychology, i.e. the concepts of "ego-development" and "transformative learning". The Nordic Secret concludes with a discussion about what we can learn from this positive transformation and how to apply it in the current global crises.
