This is an interdisciplinary study on the extreme vilification of human dignity by Nazism. It is focused on the two greatest protagonists of the sides that were confronted in those years of the most tragic uncertainty about the fate of the human species: Adolf Hitler, the genius of Nazi ideology, and Thomas Mann, his most prominent opponent in exile, spokesman for the values of Humanism and Civilisation that blew pulverised from the chimneys of concentration camps. How was Nazism possible? How can we prevent its avatars? This book presents that Nazism and the wickedness of its ghastly crimes against human dignity have anthropological roots, able to reproduce at any time and any place, and that the most powerful resource against its reproduction and for the flourishment of the human dignity is the human right to education.
