We shall not go wrong in presuming that the reader, who has patiently followed our deductions, has had for some time in his mind the question: How about the representatives of scientific research themselves? Do not a large majority of them, perhaps virtually all, stand alien and repellant to Christian faith and its fundamental truths? We do not refer to our modern philosophers, for of them it might be said that their researches yield questionable speculations of individualistic stamp, rather than exact results. But there are the representatives of the more exact sciences, especially of the most exact of all, natural science. They may be considered the legitimate representatives of modern science, since their results are the most accurate, their methods the most strictly scientific; and are they not, every one of them, opposed to Christian faith, especially to its fundamental dogma? Is not _Haeckel_ right when he states in the final summary of his “Welträtsel,” in which he so strongly insists on the incompatibility of religion and natural science: “I am supported by the accord of nearly all modern naturalists who have the courage to express their convictions”? Is it not true that _A. von Humboldt_ is considered the prince of German naturalists? and yet in his voluminous “_Kosmos_” he not once mentions the name of God? Have not, with few exceptions, German naturalists, under _Humboldt’s_ influence, turned against Christianity? (_W. Menzel_, Die letzten hundertzwanzig Jahre der Weltgeschichte, VI, 1860, p. 70; cfr. _Pohle_, P. Angelo Secchi, 1904, p. 6). Here indeed the antagonism between true scientific spirit and the faith seems to take shape in tangible reality, and to invalidate every argument to the contrary. Thus runs the speech that is ever recurring in the literature of the day, in newspapers and magazines no less than in books. And this speech makes an impression on its hearers. Indeed, why should it not? After describing how these heroes of science in recent times marched on triumphantly from victory to victory, how they renewed the face of the earth, and became the pioneers of human progress, how can they fail to make a deep impression if in the same breath they state that these discoverers of truth have, almost to a man, broken with the ancient teachings of the Christian religion? Without doubt the suggestive effect of such speculation must be very considerable with those who lack sufficient historical knowledge. The case is different with those better acquainted with the history of the natural sciences. They know that it is not true to state that the leading natural scientists, for the most part, or even unanimously, have rejected and denied Christian religion, that it is a _lie_ and a falsification of history.
