Johannes Evangelist von Kuhn (19 February 1806 – 8 May 1887) was a German Catholic theologian. With Franz Anton Staudenmaier he occupied the foremost rank among the speculative dogmatists of the Catholic school at the University of Tübingen. Life Kuhn was born in Wäschenbeuren in the Kingdom of Württemberg. He pursued his classical studies at Schwäbisch Gmünd, Ellwangen, and Rottweil, and courses in philosophy and theology from 1825 to 1830 at Tübingen; entered the seminary at Rottenburg in the autumn of 1830, and was there ordained on 14 September 1831. In the autumn of 1832, he became professor of New Testament exegesis in the Catholic theological faculty then attached to the University of Giessen. At Easter, 1837, he was called in the same capacity to the University of Tübingen, where, in 1839, he was appointed to the chair of dogmatic theology. He retired in 1882, dying five years later in Tübingen. Works His first important work was the result of his research into the new philosophy "Jacobi und die Philosophie seiner Zeit. Ein Versuch das wissenschaftliche Fundament der Philosophie historisch zu erörtern" (Mainz, 1834). During the years he taught at Giessen, his literary activity in the domain of New Testament studies resulted in a series of articles which he published in the "Jahrbücher für Theologie und christliche Philosophie" (Frankfurt, 1834-6), edited by him and by his colleagues, Johann Nepomuk Locherer, Johann Baptist Lüft, and Franz Anton Staudenmaier. His work in this field closed with the important, though unfinished work, "Das Leben Jesu wissenschaftlich bearbeitet" (Mainz, 1838), in which he opposed the critical tendencies of David Strauss. After he had taken the chair of dogmatic theology at Tübingen, he made the study of speculative dogma his life work. His most important work is the "Katholische Dogmatik," an undertaking of wide scope which was never completed. The following parts appeared: Vol. I, part I: "Einleitung in die katholische Dogmatik" (Tübingen, 1846, 2nd ed., 1859); Vol. I, part II: "Die dogmatische Lehre von der Erkenntniss, den Eigenschaften und der Einheit Gottes" (1849; 2nd ed., 1862); Vol. II: "Die christliche Lehre von der göttlichen Dreieinigkeit" (1857). Kuhn had already outlined his work in the paper "Über Princip und methode der speculativen Theologie" (University programme, Tübingen, 1840). Among his other works which were issued in part independently, and in part in the Tübingen "Theologische Quartalschrift," many bear a polemical character. His treatment of the fundamental
