Hermes, George, _Die philosophische Einleitung in die christ. katholische Theologie_, printed in 1819, prohibited in 1831. The other writings by this author, together with a long series of treatises by his followers, were for the most part prohibited. It was contended by the Hermessians, as it had formerly been contended by the Jansenists, that the specific errors on the ground of which the condemnations had been arrived at did not as a matter of fact exist in the writings of Hermes. In May, 1837, six years after the death of Hermes, Professors Braun and Elvenich journeyed to Rome for the purpose of securing a fresh examination of the works of Hermes and of establishing their orthodoxy, but after a series of conferences, they failed to secure the recall of condemnation. Günther, A., _Peregrins Gastmahl, Janusköpfe für Philosophie und Theologie_, and a group of similar writings published between 1830 and 1843, were condemned together in 1857. The Congregation of the Index began in 1851 to give special attention to Günther. In 1852, instructions were given by Pius IX to the bishop of Wurzburg to prohibit the teaching of the theories that had become known as the philosophy of Günther. Trebisch, Leop. (classed as a follower of Günther), _Die christliche Weltanschauung in ihrer Bedeutung für Wissenschaft und Leben_, printed in 1858, prohibited in 1859. Frohschammer, J., _Ueber den Ursprung der menschlichen Seelen_, printed in 1854, prohibited in 1857. The work of Frohschammer was brought upon the Index by the influence of the Jesuit Kleutgen. It is recorded that the secretary of the Congregation asked Dr. Döllinger, who was at the time in Rome, to induce Frohschammer to submit himself and to recall his treatise, but no such action was taken by the author. His later treatises, _Einleitung in die Philosophie_, _Der Grundriss der Metaphysik_, and _Ueber die Freiheit der Wissenschaft_, were prohibited together in 1862. He was suspended from his functions in 1863, and in 1871, placed under excommunication. In the introduction to the papal brief of 1863, Pius writes that he had learned with great sorrow that a number of the theologians and instructors in philosophy having chairs in the Catholic institutions of Germany had permitted themselves to bring into their teachings an unwarranted license of thought and of expression. The works through which these teachings were distributed to the general public were in many cases carrying most pernicious errors. These works, in so far as they had been examined and reported upon, the Pope had therefore ordered to be placed on the Index.
