In addition to the work of Hermann von Helmholtz and Eduard Zeller, early fruits of the movement were Kuno Fischer's works on Kant and Friedrich Albert Lange's " History of Materialism " ( " Geschichte des Materialismus " ), the latter of which argued that transcendental idealism superseded the historic struggle between material idealism and idealist Friedrich Adolf Trendelenburg concerning the interpretation of the results of the Transcendental Aesthetic, a dispute that prompted Hermann Cohen's 1871 seminal work " Kants Theorie der Erfahrung ", a book often regarded as the foundation of 20th-century neo-Kantianism.
