Another reason of a kindred nature is to be found in the difference of method by which truths are gained [pg 223] in theology and in physical science. Induction is the instrument of Physics, and deduction only is the instrument of Theology. There the simple question is, What is revealed? all doctrinal knowledge flows from one fountain head. If we are able to enlarge our view and multiply our propositions, it must be merely by the comparison and adjustment of the original truths; if we would solve new questions, it must be by consulting old answers. The notion of doctrinal knowledge absolutely novel, and of simple addition from without, is intolerable to Catholic ears, and never was entertained by any one who was even approaching to an understanding of our creed. Revelation is all in all in doctrine; the Apostles its sole depository, the inferential method its sole instrument, and ecclesiastical authority its sole sanction. The Divine Voice has spoken once for all, and the only question is about its meaning. Now this process, as far as it was reasoning, was the very mode of reasoning which, as regards physical knowledge, the school of Bacon has superseded by the inductive method:—no wonder, then, that that school should be irritated and indignant to find that a subject-matter remains still, in which their favourite instrument has no office; no wonder that they rise up against this memorial of an antiquated system, as an eyesore and an insult; and no wonder that the very force and dazzling success of their own method in its own departments should sway or bias unduly the religious sentiments of any persons who come under its influence. They assert that no new truth can be gained by deduction; Catholics assent, but add that, as regards religious truth, they have not to seek at all, for they have it already. Christian Truth is purely of revelation; that revelation we can but explain, we cannot increase, except relatively to our [pg 224] own apprehensions; without it we should have known nothing of its contents, with it we know just as much as its contents, and nothing more. And, as it was given by a divine act independent of man, so will it remain in spite of man. Niebuhr may revolutionize history, Lavoisier chemistry, Newton astronomy; but God Himself is the author as well as the subject of theology. When Truth can change, its Revelation can change; when human reason can outreason the Omniscient, then may it supersede His work.
Avowals such as these fall strange upon the ear of men whose first principle is the search after truth, and whose starting-points of search are things material and sensible. They scorn any process of inquiry not founded on experiment; the Mathematics indeed they endure, because that science deals with ideas, not with facts, and leads to conclusions hypothetical rather than real; “Metaphysics” they even use as a by-word of reproach; and Ethics they admit only on condition that it gives up conscience as its scientific ground, and bases itself on tangible utility: but as to Theology, they cannot deal with it, they cannot master it, and so they simply outlaw it and ignore it. Catholicism, forsooth, “confines the intellect,” because it holds that God's intellect is greater than theirs, and that what He has done, man cannot improve. And what in some sort justifies them to themselves in this extravagance is the circumstance that there is a religion close at their doors which, discarding so severe a tone, has actually adopted their own principle of inquiry. Protestantism treats Scripture just as they deal with Nature; it takes the sacred text as a large collection of phenomena, from which, by an inductive process, each individual Christian may arrive at just those religious conclusions which approve themselves [pg 225] to his own judgment. It considers faith a mere modification of reason, as being an acquiescence in certain probable conclusions till better are found. Sympathy, then, if no other reason, throws experimental philosophers into alliance with the enemies of Catholicism.

I have another consideration to add, not less important than any I have hitherto adduced. The physical sciences, Astronomy, Chemistry, and the rest, are doubtless engaged upon divine works, and cannot issue in untrue religious conclusions. But at the same time it must be recollected that Revelation has reference to circumstances which did not arise till after the heavens and the earth were made. They were made before the introduction of moral evil into the world: whereas the Catholic Church is the instrument of a remedial dispensation to meet that introduction. No wonder then that her teaching is simply distinct, though not divergent, from the theology which Physical Science suggests to its followers. She sets before us a number of attributes and acts on the part of the Divine Being, for which the material and animal creation gives no scope; power, wisdom, goodness are the burden of the physical world, but it does not and could not speak of mercy, long-suffering, and the economy of human redemption, and but partially of the moral law and moral goodness. “Sacred Theology,” says Lord Bacon, “must be drawn from the words and the oracles of God: not from the light of nature or the dictates of reason. It is written, that ‘the Heavens declare the glory of God;’ but we nowhere find it that the Heavens declare the will of God; which is pronounced a law and a testimony, that men [pg 226] should do according to it. Nor does this hold only in the great mysteries of the Godhead, of the creation, of the redemption.… We cannot doubt that a large part of the moral law is too sublime to be attained by the light of nature; though it is still certain that men, even with the light and law of nature, have some notions of virtue, vice, justice, wrong, good, and evil.”[28] That the new and further manifestations of the Almighty, made by Revelation, are in perfect harmony with the teaching of the natural world, forms indeed one subject of the profound work of the Anglican Bishop Butler; but they cannot in any sense be gathered from nature, and the silence of nature concerning them may easily seduce the imagination, though it has no force to persuade the reason, to revolt from doctrines which have not been authenticated by facts, but are enforced by authority. In a scientific age, then, there will naturally be a parade of what is called Natural Theology, a wide-spread profession of the Unitarian creed, an impatience of mystery, and a scepticism about miracles.
And to all this must be added the ample opportunity which physical science gives to the indulgence of those sentiments of beauty, order, and congruity, of which I have said so much as the ensigns and colours (as they may be called) of a civilized age in its warfare against Catholicism.
It being considered, then, that Catholicism differs from physical science, in drift, in method of proof, and in subject-matter, how can it fail to meet with unfair usage from the philosophers of any Institution in which there is no one to take its part? That Physical Science itself will be ultimately the loser by such ill treatment of Theology, [pg 227] I have insisted on at great length in some preceding Discourses; for to depress unduly, to encroach upon any science, and much more on an important one, is to do an injury to all. However, this is not the concern of the Church; the Church has no call to watch over and protect Science: but towards Theology she has a distinct duty: it is one of the special trusts committed to her keeping. Where Theology is, there she must be; and if a University cannot fulfil its name and office without the recognition of Revealed Truth, she must be there to see that it is a bonâ fide recognition, sincerely made and consistently acted on.
