The Impossibility of Showing What Should Never Have Happened examines the persistent impact of National Socialist child rearing ideals in post-war Germany. Specifically, it focuses on how the parenting book "The German Mother and Her First Child" by Johanna Haarer, infused with Nazi ideology, remained in publication, demonstrating the enduring influence of these ideas. The work investigates the continued existence of these harmful practices in a society supposedly moving beyond them.
