In 1795, Friedrich Schiller published his letters Über die ästhetische Erziehung des Menschen, On the Aesthetic Education of Man. In the sixth letter, he described what the division of work does to a person: Ewig nur an ein einzelnes kleines Bruchstück des Ganzen gefesselt, bildet sich der Mensch selbst nur als Bruchstück aus. Forever chained to a single small fragment of the whole, man forms himself only as a fragment. Instead of expressing humanity in his nature, Schiller wrote, he becomes merely an imprint of his occupation, of his science. Schiller’s complaint takes for granted that a person’s occupation shapes the whole person.
