title: Worthy heir or treacherous patricide? Konrad Lorenz and Jakob v. Uexküll.
abstract: The biologist Jakob v. Uexküll is often seen as the preceptor of modern behavioral theory, who lastingly influenced Konrad Lorenz in particular. Nevertheless, Uexküll has been highly inadequately received by the school Lorenz founded. This neglect of Uexküll's works resulted because Lorenz and Uexküll came into contact at a time when the biological sciences were sundered by a deep ideological division. On the one side stood the Darwin-rejecting Neo-Vitalists (for example Uexküll), on the other side were the Neo-Darwinists (for example Lorenz). After Vitalism was overcome as a consequence of the Evolutionary Synthesis, Darwinists who had taken an intermittent interest in Vitalists and their theories could now only distance themselves completely from earlier ideas. This went not only for biologists and behavioral researchers, but also for medical scientists. The emancipation from the starting points of their own science was so complete that, even decades later, when the earlier debates about Mechanism and Vitalism were long since historically outdated, behavioral research never investigated its own history.
