The believing scientist, too, will submit to correction; should the rare case fall to his lot to have the Church condemn his work, he will know how to be generously obedient. Splendid examples are blazing the way for him. “Were we to draw up a list of the scientists, who, in a similar critical position as _Fénelon_, found strength in the virtue of obedience, and on the other hand a list of all those whose subjective scientific views did not allow them to submit, then we should perceive at a glance that their proud persistence in their own opinion has been injurious to true wisdom in the same degree as humble submission proved a benefit to science” (_Hilgers_, 412). Finally, he who is convinced that the Christian faith is the greatest heritance of truth from the past, which must be preserved in him, he will take no offence if the Church is not impressed even by names like _Kant_, _Spinoza_, _Schopenhauer_, _Strauss_, men much featured as the captains of modern science and philosophy. In the eyes of the Church nothing is genuine and true science that is contrary to the testimony of God, and errors are errors even then when their perpetrator is receiving cheers and applause. Just as the state prohibits the physician from designedly assisting any one to commit suicide, even though the physician be a noted scientist, just so the Church opposes any one who assaults God’s truth, be he journalist or philosopher. Frequently the _great number of forbidden books mentioned by the Index_ is pointed out. The Index of 1900 contains about 5,000 titles belonging to the last three centuries; of these about 1,300 belong to the nineteenth century. Quite a small number, considering the immense literature of the world. Yet it will look even smaller when compared, for instance, with the censure of books by the _Prussian state_. In the year 1845 there appeared the following catalogue: “Index _librorum prohibitorum_, Catalogue of the books forbidden in Germany during 1844-1845, first volume.” The second volume was issued in 1846. The list is not complete: it does not contain, for instance, the names of prohibited newspapers and periodicals. Yet it contains 437 writings, forbidden by 570 decrees, _i.e._, two or three times as many as the entire number of German books of the nineteenth century enumerated by name in the Roman Index. The “Historisch-Politischen Blaetter” of 1840 contain an article beginning thus: “_Veritas odium parit._ In Prussia there are now prohibited nearly all Catholic journals and periodicals, and in order to begin the matter _ab ovo_ they have grasped a welcome opportunity to throw interdicts at wholesale against works not yet published, or to render their circulation difficult to a degree amounting to prohibition.”
