Über die Dummheit

Published in 1909, 'Über die Dummheit' by Leopold Loewenfeld explores the phenomenon of human stupidity, a topic that was largely unexamined at the time. The book begins with statistical studies on schoolchildren and soldiers, then delves into various aspects of intelligence, including the distinction between 'normal' stupidity and pathological conditions, as well as the influence of superstition, religion, and social factors on cognitive abilities. However, Loewenfeld also advocates for eugenics and expresses social Darwinist views, which raise ethical concerns in contemporary discussions of the text.
