German idealism
Neo-Kantianism refers broadly to a revived type of philosophy along the lines of that laid down by Immanuel Kant in the 18th century, or more specifically by Schopenhauer's criticism of the Kantian philosophy in his work "The World as Will and Representation" (1818), as well as by other post-Kantian philosophers such as Jakob Friedrich Fries and Johann Friedrich Herbart. It has some more specific reference in later German philosophy.
Karl Vorländer
Karl Vorländer (2 January 1860, Marburg – 6 December 1928, Münster) was a German neo-Kantian philosopher who taught in Solingen. He published various studies and editions of the works of Kant, including studies of the relation between Kantian thought and socialist thought, and of the influence of Kant on the work of Johann Wolfgang Goethe. His 1924 biography of Kant became a classic of Kant scholarship for much of the twentieth century.
