Hence the result of our discussion is: independent of science mankind has its positive convictions, independent of science it finds here rest and gratification in its longing for truth. Scientific study and research are for the purpose of setting these truths in a brighter light, of defending the patrimony of mankind. But the fosterer of science must not claim the freedom to ignore these positive convictions in himself and in others, to endanger the patrimony of mankind by doubts and attacks instead of protecting it, much less must he condemn the human mind to the eternal labour of _Sisyphus_, to the eternal rolling of a huge stone which, recoiling, must always be lifted anew. Chapter IV. Accusations And Objections. Among the notable facts in history one stands out prominently, it is more remarkable than any other, and evokes serious thought. It is the fact that the Christian religion, especially its foremost representative, the Catholic Church, concerning which every unbiassed critic is bound to admit that none has made more nations moral, happy and great than this Church; that nowhere else has virtue and holiness flourished more than in her; that no one else has laboured more for truth and purity of morals; that nevertheless there is not, and never was, an institution which has more enemies, which has been more persecuted, than the Catholic Church. This fact will suggest to every serious-minded critic the question, whether we have not here focussed that tremendous struggle, which truth and justice have ever waged in the bosom of mankind against error and passions—an image of the struggle raging in every human breast. The Church recognizes in this fact the fulfilment of the prophecy of her Founder: “And ye shall be hated by all men for my name’s sake” (Luke xxi. 17). And the Church may add, that in her alone this prophecy is being fulfilled. The Enemy of Progress.
