Eucken, Rudolf Christoph

German Idealist philosopher, winner of the Nobel Prize for Literature (1908), interpreter of Aristotle, and author of works in ethics and religion.
Eucken studied at the University of Gottingen under the German thinker Rudolf Hermann Lotze, a teleological Idealist, and at Berlin under Friedrich Adolf Trendelenburg, a German philosopher whose ethical concerns and historical treatment of philosophy attracted him. Appointed professor of philosophy at the University of Basel, Switz., in 1871, Eucken left in 1874 to become professor of philosophy at the University of Jena, a position he held until 1920.
Distrusting abstract intellectualism and systematics, Eucken centred his philosophy upon actual human experience. He maintained that man is the meeting place of nature and spirit and that it is his duty and his privilege to overcome his nonspiritual nature by incessant active striving after the spiritual life. This pursuit, sometimes termed ethical activism, involves all of man's faculties but especially requires efforts of the will and intuition.

A strident critic of naturalist philosophy, Eucken held that man's soul differentiated him from the rest of the natural world and that the soul could not be explained only by reference to natural processes. His criticisms are particularly evident in Individual and Society (1923) and Der Sozialismus und seine Lebensgestaltung (1920; Socialism: An Analysis, 1921). The second work attacked Socialism as a system that limits human freedom and denigrates spiritual and cultural aspects of life.

Eucken's Nobel Prize diploma referred to the "warmth and strength in presentation with which in his numerous works he has vindicated and developed an idealist philosophy of life." His other works include Der Sinn und Wert des Lebens (1908; The Meaning and Value of Life, 1909) and Konnen wir noch Christen sein? (1911; Can We Still Be Christians?, 1914).
