Kantianism
Kantianism is the philosophy of Immanuel Kant, a German philosopher born in Königsberg, Prussia (now Kaliningrad, Russia). The term "Kantianism" or "Kantian" is sometimes also used to describe contemporary positions in philosophy of mind, epistemology, and ethics.
Salomo Friedlaender
Between 1894 and 1902, Friedlaender studied medicine, philosophy, German literature, archaeology, and art history in Munich, Berlin, and Jena. He wrote his dissertation on Arthur Schopenhauer and Kant. He approached the contemporary problems of his day through the lens of Kantian philosophy, in the footsteps of his teacher, the neo-Kantian Ernst Marcus. His most philosophical work, "Die schoepferische Indifferenz" (1918), Friedlaender built upon Kant's ideas to move beyond the classical dualism of subject and object in a purified, absolute self.
