The 1920 essay by German attorney Karl Binding and psychiatrist Alfred Hoche, "Permitting the Destruction of Life Unworthy of Life," is often characterized as a stepping-stone toward the Nazi genocide policies. A careful review of Binding and Hoche's arguments does reveal elements that foreshadow Nazi thinking, but it also contains points that fail to parallel--or that directly contradict--Nazi death practices. A proper ethical and historical analysis of this work requires a more nuanced discussion than it often receives.
