Childhood 6.7, researched investigatively for years, is a story of childhood and at the same time a critique of civilization. It is a passionate plea and manifesto for a more dignified and species-appropriate upbringing of children, for a new appreciation of familial socialization, and for complete educational freedom. Finally, a book that gathers so many well-founded arguments, clearly demonstrating that our education system cannot continue as it has been. Hopefully, it will soon become required reading for all those responsible for education and upbringing, and a favorite read for parents. Prof. Gerald Hüther, neurobiologist, bestselling author. Childhood 6.7 is a masterpiece that not only conveys a wealth of researched realities but is also enriched with comprehensible interpretations. Dr. H.-J. Maaz, psychoanalyst, bestselling author.
