What has just been said about the Catholic being excluded, could easily be exemplified by a lengthy list of facts. But we shall pass them over. We shall note one utterance only, from the pen of a non-Catholic writer. The renowned pedagogue, _Fr. W. Foerster_, says in the preface to the second edition of his book on “Sexual Ethics and Sexual Pedagogy”: “Special exception has been taken to the catholicizing tendency of my book, and not infrequently the author has without further ado been made out an orthodox Catholic. For many years past I have been in a position to gain interesting information concerning the incredible bias of many champions of unprepossessed research. To them it is an a-priori dogma that everything represented by the Catholic Church is nonsense, superstition, bigotry. They are past comprehending how an unprejudiced man, simply by concrete experience, unprepossessed research and serious pondering in the field of pedagogy, could be brought to affirm that certain notions of the Roman Catholic Church are the unavoidable consequence of a penetrating knowledge of soul and life. This cannot be admitted by the non-Catholic: for him the truth must cease where the Catholic faith begins; he dares not assent to anything, else he will no longer be taken for a reputable scientific man.” The bluster about unprepossession proceeds from _shallowness and dishonesty_. The most varied presumptions, that have nothing to do with science and the pursuit of the truth, may pass without notice; only when Christian and Catholic religious convictions, resting upon divine authority, are encountered, then tolerance gives way to excitement, a hue and cry is raised, the gate is shut, and entrance to the scientific world denied. Philosophers arise, and each philosophizes according to his manner. _Fichte_ says: “What philosophy to choose depends on the kind of a man one is.” The historian enters. It is reported that _Treitschke_ said: “If I cannot write history from my own view-point, with my own judgment, then I had rather be a soapmaker.” According to trustworthy testimony, the well-known Protestant historian, _Giesebrecht_, used to preface his lectures in Munich with the words: “I am a Prussian and a Protestant: I shall lecture accordingly” (Hochschulnachrichten, 1901, 2, p. 30). Even here there are no objections in the name of Unprepossession. “Science,” says _Harnack_, “will tear off the mask of the hypocrite or plagiarist and throw him out of the temple, but the queerest suppositions it must let pass if they go by the name of convictions, and if those who harbour them are trying to demonstrate them by scientific means.”
