If then, Gentlemen, I now resist such a course of acting as unphilosophical, what is this but to do as men of Science do when the interests of their own respective pursuits are at stake? If they certainly would resist the divine who determined the orbit of Jupiter by the Pentateuch, why am I to be accused of cowardice or illiberality, because I will not tolerate their attempt in turn to theologize by means of astronomy? And if experimentalists would be sure to cry out, did I attempt to install the Thomist philosophy in the schools of astronomy and medicine, why may not I, when Divine Science is ostracized, and La Place, or Buffon, or Humboldt, sits down in its chair, why may not I fairly protest against their exclusiveness, and demand the emancipation of Theology? 15. And now I consider I have said enough in proof of the first point, which I undertook to maintain, viz., the claim of Theology to be represented among the Chairs of a University. I have shown, I think, that exclusiveness really attaches, not to those who support that claim, but to those who dispute it. I have argued in its behalf, first, from the consideration that, whereas it is the very profession of a University to teach all sciences, on this account it cannot exclude Theology without being untrue to its profession. Next, I have said that, all sciences being connected together, and having bearings one on another, it is impossible to teach them all thoroughly, unless they all are taken into account, and Theology among them. Moreover, I have insisted on the important influence, which Theology in matter of fact does and must exercise over a great variety of sciences, completing and correcting them; so that, granting it to be a real science occupied upon truth, it cannot be omitted without great prejudice to the teaching of the rest. And lastly, I have urged that, supposing Theology be not taught, its province will not simply be neglected, but will be actually usurped by other sciences, which will teach, without warrant, conclusions of their own in a subject-matter which needs its own proper principles for its due formation and disposition. Abstract statements are always unsatisfactory; these, as I have already observed, could be illustrated at far greater length than the time allotted to me for the purpose has allowed. Let me hope that I have said enough upon the subject to suggest thoughts, which those who take an interest in it may pursue for themselves. Discourse V. Knowledge Its Own End.
