Immanuel Kant
Immanuel Kant (; ; 22 April 1724 – 12 February 1804) was a German philosopher who is a central figure in modern philosophy. In his doctrine of transcendental idealism, he argued that space, time and causation are mere sensibilities; "things-in-themselves" exist, but their nature is unknowable. In his view, the mind shapes and structures experience, with all human experience sharing certain structural features. He drew a parallel to the Copernican revolution in his proposition that worldly objects can be intuited "a priori" ("beforehand"), and that intuition is therefore independent from objective reality. Kant believed that reason is the source of morality, and that aesthetics arise from a faculty of disinterested judgment. Kant's views continue to have a major influence on contemporary philosophy, especially the fields of epistemology, ethics, political theory, and post-modern aesthetics.
Culture of Germany
German philosophers have helped shape western philosophy from as early as the Middle Ages (Albertus Magnus). Later, Leibniz (17th century) and most importantly Kant played central roles in the history of philosophy. Kantianism inspired the work of Schopenhauer and Nietzsche as well as German idealism defended by Fichte and Hegel. Marx and Engels developed communist theory in the second half of the 19th century while Heidegger and Gadamer pursued the tradition of German philosophy in the 20th century. A number of German intellectuals were also influential in sociology, most notably Adorno, Elias, Habermas, Horkheimer, Luhmann, Marcuse, Simmel, Tönnies, and Weber. The University of Berlin founded in 1810 by linguist and philosopher Wilhelm von Humboldt served as an influential model for a number of modern western universities.
