Born in Biebrich, Rhineland (now Hesse, Germany), the German philosopher and psychologist Wilhelm Christian Ludwig Dilthey founded the German school of philosophy called Lebensphilosophie (philosophy of life). He studied theology, history and philosophy in Heidelberg and Berlin, and in 1864 he was awarded a doctorate for his dissertation on the ethics of Friedrich Schleiermacher (1768–1834). After holding professorships in Basel, Kiel and Breslau, he became a professor of philosophy at the University of Berlin in 1882. In his Einleitung in die Geisteswissenschaften (vol. 1, 1883; Introduction to the Human Sciences), he defined the common method of the humanities.
