Born in Peine near Hanover, Otto attended the Gymnasium Andreanum in Hildesheim and studied at the universities of Erlangen and Göttingen, where he wrote his dissertation on Martin Luther's understanding of the Holy Spirit, and his habilitation on Kant. By 1906, he held a position as extraordinary professor, and in 1910 he received an honorary doctorate from the University of Giessen. In 1915, he became ordinary professor at the University of Breslau, and in 1917, at the University of Marburg's Divinity School, then one of the most famous Protestant seminaries in the world. Although he received several other calls, he remained in Marburg for the rest of his life. He retired in 1929 and died of pneumonia eight years later, after he had suffered serious injuries falling some 20 m from a tower. Persistent but unconfirmed rumors identified this as a suicide attempt. He is buried in Marburg cemetery.
The Idea of the HolyEdit
Otto's most famous work is The Idea of the Holy, published first in 1917 as Das Heilige - Über das Irrationale in der Idee des Göttlichen und sein Verhältnis zum Rationalen (The Holy - On the Irrational in the Idea of the Divine and its Relation to the Rational). It is one of the most successful German theological books of the 20th century, has never gone out of print, and is now available in about 20 languages. The book defines the concept of the holy as that which is numinous. Otto explained the numinous as a "non-rational, non-sensory experience or feeling whose primary and immediate object is outside the self". He coined this new term based on the Latin numen (deity). This expression is etymologically unrelated to Immanuel Kant's noumenon, a Greek term referring to an unknowable reality underlying all things. The numinous is a mystery (Template:Lang-la) that is both terrifying (tremendum) and fascinating (fascinans) at the same time. It also sets a paradigm for the study of religion that focuses on the need to realize the religious as a non-reducible, original category in its own right. This paradigm was under much attack between approximately 1950 and 1990 but has made a strong comeback since then, after its phenomenological aspects have become more apparent.
Otto left a broad influence on theology and philosophy of religion in the first half of the 20th century. German-American theologian Paul Tillich acknowledged Otto's influence on him, as did Romanian-American philosopher Mircea Eliade and Otto's most famous German pupil Gustav Mensching (1901-1978) from Bonn University. Eliade used the concepts from The Idea of the Holy as the starting point for his own 1957 book, The Sacred and the Profane. Otto was one of the very few modern theologians to whom C. S. Lewis indicates a debt, particularly the idea of the numinous in The Problem of Pain. Others to acknowledge Otto were, for instance, Martin Heidegger, Leo Strauss, John A. Sanford, Hans-Georg Gadamer (critical in his youth, respectful in his old age), Max Scheler, Ernst Jünger, Joseph Needham and Hans Jonas.
