A Grave Warning!
Over 150 years ago a brilliant man laid down principles of education, of pedagogy - indeed, of epistemology perhaps - and touched on the structure underlying Subsidiarity, of right relation, of the order of all beings created by God. In his great work, he gave a severe warning to academics and educators, whether Catholic or otherwise - to all those who refuse to be catholic:
I have said that all branches of knowledge are connected together, because the subject-matter of knowledge is intimately united in itself, as being the acts and the work of the Creator. Hence it is that the Sciences, into which our knowledge may be said to be cast, have multiplied bearings one on another, and an internal sympathy, and admit, or rather demand, comparison and adjustment. They complete, correct, balance each other. This consideration, if well-founded, must be taken into account, not only as regards the attainment of truth, which is their common end, but as regards the influence they exercise upon those whose education consists in the study of them. I have said already, that to give undue prominence to one is to be unjust to another; to neglect or supersede these is to divert those from their proper object. It is to unsettle the boundary lines between science and science, to disturb their action, to destroy the harmony which binds them together. Such a proceeding will have a corresponding effect when introduced into a place of education. There is no science but tells a different tale, when viewed as a portion of a whole, from what it is likely to suggest when taken by itself, without the safeguard, as I may call it, of others.
I observe, then, that, if you drop any science out of the circle of knowledge, you cannot keep its place vacant for it; that science is forgotten; the other sciences close up, or, in other words, they exceed their proper bounds, and intrude where they have no right. For instance, I suppose, if ethics were sent into banishment, its territory would soon disappear, under a treaty of partition, as it may be called, between law, political economy, and physiology; what, again, would become of the province of experimental science, if made over to the Antiquarian Society; or of history, if surrendered out and out to Metaphysicians? The case is the same with the subject-matter of Theology; it would be the prey of a dozen various sciences, if Theology were put out of possession; and not only so, but those sciences would be plainly exceeding their rights and their capacities in seizing upon it. They would be sure to teach wrongly, where they had no mission to teach at all. The enemies of Catholicism ought to be the last to deny this: - for they have never been blind to a like usurpation, as they have called it, on the part of theologians; those who accuse us of wishing, in accordance with Scripture language, to make the sun go round the earth, are not the men to deny that a science which exceeds its limits falls into error.
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?
