If we adopt this view, we can find a means of reconciling the two great and apparently quite distinct branches in the idea I put forward in "Monism, as a Connecting-Link between Religion and Science," in 1892. In the preface to this _Confession of Faith of a Man of Science_ I expressed myself in the following words with regard to its double object: "In the first place, I must give expression to the rational system which is logically forced upon us by the recent progress of science; it dwells in the intimate thoughts of nearly every impartial and thoughtful scientist, though few have the courage or the disposition to avow it. In the second place, I would make of it a connecting-link between religion and science, and thus do away with the antithesis which has been needlessly maintained between these two branches of the highest activity of the human mind. The ethical craving of our emotion is satisfied by monism no less than the logical demand for causality on the part of reason." The remarkable interest which the discourse enkindled is a proof that in this monistic profession of faith I expressed the feeling not only of many scientists, but of a large number of cultured men and women of very different circles. Not only was I rewarded by hundreds of sympathetic letters, but by a wide circulation of the printed address, of which six editions were required within six months. I had the more reason to be content with this unexpected success, as this "confession of faith" was originally merely an occasional speech which I delivered unprepared on October 9, 1892, at Altenburg, during the jubilee of the Scientific Society of East Germany. Naturally there was the usual demonstration on the other side; I was fiercely attacked, not only by the ultramontane press, the sworn defenders of superstition, but also by the "liberal" controversialists of evangelical Christianity, who profess to defend both scientific truth and purified faith. In the seven years that have ensued since that time the great struggle between modern science and orthodox Christianity has become more threatening; it has grown more dangerous for science in proportion as Christianity has found support in an increasing mental and political reaction. In some countries the Church has made such progress that the freedom of thought and conscience, which is guaranteed by the laws, is in practice gravely menaced (for instance, in Bavaria). The great historic struggle which Draper has so admirably depicted in his _Conflict between Religion and Science_ is to-day more acute and significant than ever. For the last twenty-seven years it has been rightly called the "_cultur-kampf_."
