Lecture VIII.
Christianity And Scientific Investigation. A Lecture Written for the School of Science.

1.
This is a time, Gentlemen, when not only the Classics, but much more the Sciences, in the largest sense of the word, are looked upon with anxiety, not altogether ungrounded, by religious men; and, whereas a University such as ours professes to embrace all departments and exercises of the intellect, and since I for my part wish to stand on good terms with all kinds of knowledge, and have no intention of quarrelling with any, and would open my heart, if not my intellect (for that is beyond me), to the whole circle of truth, and would tender at least a recognition and hospitality even to those studies which are strangers to me, and would speed them on their way,—therefore, as I have already been making overtures of reconciliation, first between Polite Literature and Religion, and next between Physics and Theology, so I would now say a word by way of deprecating and protesting against the needless antagonism, which sometimes exists in fact, between divines and the cultivators of the Sciences generally.

2.
Here I am led at once to expatiate on the grandeur of an Institution which is comprehensive enough to admit the discussion of a subject such as this. Among the objects of human enterprise,—I may say it surely without extravagance, Gentlemen,—none higher or nobler can be named than that which is contemplated in the erection of a University. To set on foot and to maintain in life and vigour a real University, is confessedly, as soon as the word “University” is understood, one of those greatest works, great in their difficulty and their importance, on which are deservedly expended the rarest intellects and the most varied endowments. For, first of all, it professes to teach whatever has to be taught in any whatever department of human knowledge, and it embraces in its scope the loftiest subjects of human thought, and the richest fields of human inquiry. Nothing is too vast, nothing too subtle, nothing too distant, nothing too minute, nothing too discursive, nothing too exact, to engage its attention.

This, however, is not the reason why I claim for it so sovereign a position; for, to bring schools of all knowledge under one name, and call them a University, may be fairly said to be a mere generalization; and to proclaim that the prosecution of all kinds of knowledge to their utmost limits demands the fullest reach and range of our intellectual faculties is but a truism. My reason for speaking of a University in the terms on which I have ventured is, not that it occupies the whole territory of knowledge merely, but that it is the very realm; that it professes much more than to take in and to lodge as in a caravanserai all art and science, all history and philosophy. In truth, it professes to assign to each study, which it receives, its own proper place and its just boundaries; to define the rights, to establish the mutual relations, and to effect the intercommunion of one and all; to keep in check the ambitious and encroaching, and to succour and maintain those which from time to time are succumbing under the more popular or the more fortunately circumstanced; to keep the peace between them all, and to convert their mutual differences and contrarieties into the common good. This, Gentlemen, is why I say that to erect a University is at once so arduous and beneficial an undertaking, viz., because it is pledged to admit, without fear, without prejudice, without compromise, all comers, if they come in the name of Truth; to adjust views, and experiences, and habits of mind the most independent and dissimilar; and to give full play to thought and erudition in their most original forms, and their most intense expressions, and in their most ample circuit. Thus to draw many things into one, is its special function; and it learns to do it, not by rules reducible to writing, but by sagacity, wisdom, and forbearance, acting upon a profound insight into the subject-matter of knowledge, and by a vigilant repression of aggression or bigotry in any quarter.

We count it a great thing, and justly so, to plan and carry out a wide political organization. To bring under one yoke, after the manner of old Rome, a hundred discordant peoples; to maintain each of them in its own privileges within its legitimate range of action; to allow them severally the indulgence of national feelings, and the stimulus of rival interests; and yet withal to blend them into one great social establishment, and to pledge them to the perpetuity of the one imperial power;—this is an achievement which carries with it the unequivocal token of genius in the race which effects it.

“Tu regere imperio populos, Romane, memento.”

This was the special boast, as the poet considered it, of the Roman; a boast as high in its own line as that other boast, proper to the Greek nation, of literary pre-eminence, of exuberance of thought, and of skill and refinement in expressing it.

What an empire is in political history, such is a University in the sphere of philosophy and research. It is, as I have said, the high protecting power of all knowledge and science, of fact and principle, of inquiry and discovery, of experiment and speculation; it maps out the territory of the intellect, and sees that the boundaries of each province are religiously respected, and that there is neither encroachment nor surrender on any side. It acts as umpire between truth and truth, and, taking into account the nature and importance of each, assigns to all their due order of precedence. It maintains no one department of thought exclusively, however ample and noble; and it sacrifices none. It is deferential and loyal, according to their respective weight, to the claims of literature, of physical research, of history, of metaphysics, of theological science. It is impartial towards them all, and promotes each in its own place and for its own object. It is ancillary certainly, and of necessity, to the Catholic Church; but in the same way that one of the Queen’s judges is an officer of the Queen’s, and nevertheless determines certain legal proceedings between the Queen and her subjects. It is ministrative to the Catholic Church, first, because truth of any kind can but minister to truth; and next, still more, because Nature ever will pay homage to Grace, and Reason cannot but illustrate and defend Revelation; and thirdly, because the Church has a sovereign authority, and, when she speaks _ex cathedra_, must be obeyed. But this is the remote end of a University; its immediate end (with which alone we have here to do) is to secure the due disposition, according to one sovereign order, and the cultivation in that order, of all the provinces and methods of thought which the human intellect has created.

In this point of view, its several professors are like the ministers of various political powers at one court or conference. They represent their respective sciences, and attend to the private interests of those sciences respectively; and, should dispute arise between those sciences, they are the persons to talk over and arrange it, without risk of extravagant pretensions on any side, of angry collision, or of popular commotion. A liberal philosophy becomes the habit of minds thus exercised; a breadth and spaciousness of thought, in which lines, seemingly parallel, may converge at leisure, and principles, recognized as incommensurable, may be safely antagonistic.

3.
And here, Gentlemen, we recognize the special character of the Philosophy I am speaking of, if Philosophy it is to be called, in contrast with the method of a strict science or system. Its teaching is not founded on one idea, or reducible to certain formulæ. Newton might discover the great law of motion in the physical world, and the key to ten thousand phenomena; and a similar resolution of complex facts into simple principles may be possible in other departments of nature; but the great Universe itself, moral and material, sensible and supernatural, cannot be gauged and meted by even the greatest of human intellects, and its constituent parts admit indeed of comparison and adjustment, but not of fusion. This is the point which bears directly on the subject which I set before me when I began, and towards which I am moving in all I have said or shall be saying.

I observe, then, and ask you, Gentlemen, to bear in mind, that the philosophy of an imperial intellect, for such I am considering a University to be, is based, not so much on simplification as on discrimination. Its true representative defines, rather than analyzes. He aims at no complete catalogue, or interpretation of the subjects of knowledge, but a following out, as far as man can, what in its fulness is mysterious and unfathomable. Taking into his charge all sciences, methods, collections of facts, principles, doctrines, truths, which are the reflexions of the universe upon the human intellect, he admits them all, he disregards none, and, as disregarding none, he allows none to exceed or encroach. His watchword is, Live and let live. He takes things as they are; he submits to them all, as far as they go; he recognizes the insuperable lines of demarcation which run between subject and subject; he observes how separate truths lie relatively to each other, where they concur, where they part company, and where, being carried too far, they cease to be truths at all. It is his office to determine how much can be known in each province of thought; when we must be contented not to know; in what direction inquiry is hopeless, or on the other hand full of promise; where it gathers into coils insoluble by reason, where it is absorbed in mysteries, or runs into the abyss. It will be his care to be familiar with the signs of real and apparent difficulties, with the methods proper to particular subject-matters, what in each particular case are the limits of a rational scepticism, and what the claims of a peremptory faith. If he has one cardinal maxim in his philosophy, it is, that truth cannot be contrary to truth; if he has a second, it is, that truth often _seems_ contrary to truth; and, if a third, it is the practical conclusion, that we must be patient with such appearances, and not be hasty to pronounce them to be really of a more formidable character.

It is the very immensity of the system of things, the human record of which he has in charge, which is the reason of this patience and caution; for that immensity suggests to him that the contrarieties and mysteries, which meet him in the various sciences, may be simply the consequences of our necessarily defective comprehension. There is but one thought greater than that of the universe, and that is the thought of its Maker. If, Gentlemen, for one single instant, leaving my proper train of thought, I allude to our knowledge of the Supreme Being, it is in order to deduce from it an illustration bearing upon my subject. He, though One, is a sort of world of worlds in Himself, giving birth in our minds to an indefinite number of distinct truths, each ineffably more mysterious than any thing that is found in this universe of space and time. Any one of His attributes, considered by itself, is the object of an inexhaustible science: and the attempt to reconcile any two or three of them together,—love, power, justice, sanctity, truth, wisdom,—affords matter for an everlasting controversy. We are able to apprehend and receive each divine attribute in its elementary form, but still we are not able to accept them in their infinity, either in themselves or in union with each other. Yet we do not deny the first because it cannot be perfectly reconciled with the second, nor the second because it is in apparent contrariety with the first and the third. The case is the same in its degree with His creation material and moral. It is the highest wisdom to accept truth of whatever kind, wherever it is clearly ascertained to be such, though there be difficulty in adjusting it with other known truth.

Instances are easily producible of that extreme contrariety of ideas, one with another, which the contemplation of the Universe forces upon our acceptance, making it clear to us that there is nothing irrational in submitting to undeniable incompatibilities, which we call apparent, only because, if they were not apparent but real, they could not co-exist. Such, for instance, is the contemplation of Space; the existence of which we cannot deny, though its idea is capable, in no sort of posture, of seating itself (if I may so speak) in our minds;—for we find it impossible to say that it comes to a limit anywhere; and it is incomprehensible to say that it runs out infinitely; and it seems to be unmeaning if we say that it does not exist till bodies come into it, and thus is enlarged according to an accident.

And so again in the instance of Time. We cannot place a beginning to it without asking ourselves what was before that beginning; yet that there should be no beginning at all, put it as far back as we will, is simply incomprehensible. Here again, as in the case of Space, we never dream of denying the existence of what we have no means of understanding.

And, passing from this high region of thought (which, high as it may be, is the subject even of a child’s contemplations), when we come to consider the mutual action of soul and body, we are specially perplexed by incompatibilities which we can neither reject nor explain. How it is that the will can act on the muscles, is a question of which even a child may feel the force, but which no experimentalist can answer.

Further, when we contrast the physical with the social laws under which man finds himself here below, we must grant that Physiology and Social Science are in collision. Man is both a physical and a social being; yet he cannot at once pursue to the full his physical end and his social end, his physical duties (if I may so speak) and his social duties, but is forced to sacrifice in part one or the other. If we were wild enough to fancy that there were two creators, one of whom was the author of our animal frames, the other of society, then indeed we might understand how it comes to pass that labour of mind and body, the useful arts, the duties of a statesman, government, and the like, which are required by the social system, are so destructive of health, enjoyment, and life. That is, in other words, we cannot adequately account for existing and undeniable truths except on the hypothesis of what we feel to be an absurdity.

And so in Mathematical Science, as has been often insisted on, the philosopher has patiently to endure the presence of truths, which are not the less true for being irreconcileable with each other. He is told of the existence of an infinite number of curves, which are able to divide a space, into which no straight line, though it be length without breadth, can even enter. He is told, too, of certain lines, which approach to each other continually, with a finite distance between them, yet never meet; and these apparent contrarieties he must bear as he best can, without attempting to deny the existence of the truths which constitute them in the Science in question.

4.
Now, let me call your attention, Gentlemen, to what I would infer from these familiar facts. It is, to urge you with an argument _à fortiori_: viz., that, as you exercise so much exemplary patience in the case of the inexplicable truths which surround so many departments of knowledge, human and divine, viewed in themselves; as you are not at once indignant, censorious, suspicious, difficult of belief, on finding that in the secular sciences one truth is incompatible (according to our human intellect) with another or inconsistent with itself; so you should not think it very hard to be told that there exists, here and there, not an inextricable difficulty, not an astounding contrariety, not (much less) a contradiction as to clear facts, between Revelation and Nature; but a hitch, an obscurity, a divergence of tendency, a temporary antagonism, a difference of tone, between the two,—that is, between Catholic opinion on the one hand, and astronomy, or geology, or physiology, or ethnology, or political economy, or history, or antiquities, on the other. I say that, as we admit, because we are Catholics, that the Divine Unity contains in it attributes, which, to our finite minds, appear in partial contrariety with each other; as we admit that, in His revealed Nature are things, which, though not opposed to Reason, are infinitely strange to the Imagination; as in His works we can neither reject nor admit the ideas of space, and of time, and the necessary properties of lines, without intellectual distress, or even torture; really, Gentlemen, I am making no outrageous request, when, in the name of a University, I ask religious writers, jurists, economists, physiologists, chemists, geologists, and historians, to go on quietly, and in a neighbourly way, in their own respective lines of speculation, research, and experiment, with full faith in the consistency of that multiform truth, which they share between them, in a generous confidence that they will be ultimately consistent, one and all, in their combined results, though there may be momentary collisions, awkward appearances, and many forebodings and prophecies of contrariety, and at all times things hard to the Imagination, though not, I repeat, to the Reason. It surely is not asking them a great deal to beg of them,—since they are forced to admit mysteries in the truths of Revelation, taken by themselves, and in the truths of Reason, taken by themselves—to beg of them, I say, to keep the peace, to live in good will, and to exercise equanimity, if, when Nature and Revelation are compared with each other, there be, as I have said, discrepancies,—not in the issue, but in the reasonings, the circumstances, the associations, the anticipations, the accidents, proper to their respective teachings.

It is most necessary to insist seriously and energetically on this point, for the sake of Protestants, for they have very strange notions about us. In spite of the testimony of history the other way, they think that the Church has no other method of putting down error than the arm of force, or the prohibition of inquiry. They defy us to set up and carry on a School of Science. For their sake, then, I am led to enlarge upon the subject here. I say, then, he who believes Revelation with that absolute faith which is the prerogative of a Catholic, is not the nervous creature who startles at every sudden sound, and is fluttered by every strange or novel appearance which meets his eyes. He has no sort of apprehension, he laughs at the idea, that any thing can be discovered by any other scientific method, which can contradict any one of the dogmas of his religion. He knows full well there is no science whatever, but, in the course of its extension, runs the risk of infringing, without any meaning of offence on its own part, the path of other sciences and he knows also that, if there be any one science which, from its sovereign and unassailable position can calmly bear such unintentional collisions on the part of the children of earth, it is Theology. He is sure, and nothing shall make him doubt, that, if anything seems to be proved by astronomer, or geologist, or chronologist, or antiquarian, or ethnologist, in contradiction to the dogmas of faith, that point will eventually turn out, first, _not_ to be proved, or, secondly, not _contradictory_, or thirdly, not contradictory to any thing _really revealed_, but to something which has been confused with revelation. And if, at the moment, it appears to be contradictory, then he is content to wait, knowing that error is like other delinquents; give it rope enough, and it will be found to have a strong suicidal propensity. I do not mean to say he will not take his part in encouraging, in helping forward the prospective suicide; he will not only give the error rope enough, but show it how to handle and adjust the rope;—he will commit the matter to reason, reflection, sober judgment, common sense; to Time, the great interpreter of so many secrets. Instead of being irritated at the momentary triumph of the foes of Revelation, if such a feeling of triumph there be, and of hurrying on a forcible solution of the difficulty, which may in the event only reduce the inquiry to an inextricable tangle, he will recollect that, in the order of Providence, our seeming dangers are often our greatest gains; that in the words of the Protestant poet,

The clouds you so much dread Are big with mercy, and shall break In blessings on your head.

5.
To one notorious instance indeed it is obvious to allude here. When the Copernican system first made progress, what religious man would not have been tempted to uneasiness, or at least fear of scandal, from the seeming contradiction which it involved to some authoritative tradition of the Church and the declaration of Scripture? It was generally received, as if the Apostles had expressly delivered it both orally and in writing, as a truth of Revelation, that the earth was stationary, and that the sun, fixed in a solid firmament, whirled round the earth. After a little time, however, and on full consideration, it was found that the Church had decided next to nothing on questions such as these, and that Physical Science might range in this sphere of thought almost at will, without fear of encountering the decisions of ecclesiastical authority. Now, besides the relief which it afforded to Catholics to find that they were to be spared this addition, on the side of Cosmology, to their many controversies already existing, there is something of an argument in this very circumstance in behalf of the divinity of their Religion. For it surely is a very remarkable fact, considering how widely and how long one certain interpretation of these physical statements in Scripture had been received by Catholics, that the Church should not have formally acknowledged it. Looking at the matter in a human point of view, it was inevitable that she should have made that opinion her own. But now we find, on ascertaining where we stand, in the face of the new sciences of these latter times, that in spite of the bountiful comments which from the first she has ever been making on the sacred text, as it is her duty and her right to do, nevertheless, she has never been led formally to explain the texts in question, or to give them an authoritative sense which modern science may question.

Nor was this escape a mere accident, but rather the result of a providential superintendence; as would appear from a passage of history in the dark age itself. When the glorious St. Boniface, Apostle of Germany, great in sanctity, though not in secular knowledge, complained to the Holy See that St. Virgilius taught the existence of the Antipodes, the Holy See was guided what to do; it did not indeed side with the Irish philosopher, which would have been going out of its place, but it passed over, in a matter not revealed, a philosophical opinion.

Time went on; a new state of things, intellectual and social, came in; the Church was girt with temporal power; the preachers of St. Dominic were in the ascendant: now at length we may ask with curious interest, did the Church alter her ancient rule of action, and proscribe intellectual activity? Just the contrary; this is the very age of Universities; it is the classical period of the schoolmen; it is the splendid and palmary instance of the wise policy and large liberality of the Church, as regards philosophical inquiry. If there ever was a time when the intellect went wild, and had a licentious revel, it was at the date I speak of. When was there ever a more curious, more meddling, bolder, keener, more penetrating, more rationalistic exercise of the reason than at that time? What class of questions did that subtle, metaphysical spirit not scrutinize? What premiss was allowed without examination? What principle was not traced to its first origin, and exhibited in its most naked shape? What whole was not analyzed? What complex idea was not elaborately traced out, and, as it were, finely painted for the contemplation of the mind, till it was spread out in all its minutest portions as perfectly and delicately as a frog’s foot shows under the intense scrutiny of the microscope? Well, I repeat, here was something which came somewhat nearer to Theology than physical research comes; Aristotle was a somewhat more serious foe then, beyond all mistake, than Bacon has been since. Did the Church take a high hand with philosophy then? No, not though that philosophy was metaphysical. It was a time when she had temporal power, and could have exterminated the spirit of inquiry with fire and sword; but she determined to put it down by _argument_, she said: “Two can play at that, and my argument is the better.” She sent her controversialists into the philosophical arena. It was the Dominican and Franciscan doctors, the greatest of them being St. Thomas, who in those medieval Universities fought the battle of Revelation with the weapons of heathenism. It was no matter whose the weapon was; truth was truth all the world over. With the jawbone of an ass, with the skeleton philosophy of pagan Greece, did the Samson of the schools put to flight his thousand Philistines.

Here, Gentlemen, observe the contrast exhibited between the Church herself, who has the gift of wisdom, and even the ablest, or wisest, or holiest of her children. As St. Boniface had been jealous of physical speculations, so had the early Fathers shown an extreme aversion to the great heathen philosopher whom I just now named, Aristotle. I do not know who of them could endure him; and when there arose those in the middle age who would take his part, especially since their intentions were of a suspicious character, a strenuous effort was made to banish him out of Christendom. The Church the while had kept silence; she had as little denounced heathen philosophy in the mass as she had pronounced upon the meaning of certain texts of Scripture of a cosmological character. From Tertullian and Caius to the two Gregories of Cappadocia, from them to Anastasius Sinaita, from him to the school of Paris, Aristotle was a word of offence; at length St. Thomas made him a hewer of wood and drawer of water to the Church. A strong slave he is; and the Church herself has given her sanction to the use in Theology of the ideas and terms of his philosophy.

6.
Now, while this free discussion is, to say the least, so safe for Religion, or rather so expedient, it is on the other hand simply necessary for progress in Science; and I shall now go on to insist on this side of the subject. I say, then, that it is a matter of primary importance in the cultivation of those sciences, in which truth is discoverable by the human intellect, that the investigator should be free, independent, unshackled in his movements; that he should be allowed and enabled, without impediment, to fix his mind intently, nay, exclusively, on his special object, without the risk of being distracted every other minute in the process and progress of his inquiry, by charges of temerariousness, or by warnings against extravagance or scandal. But in thus speaking, I must premise several explanations, lest I be misunderstood.

First, then, Gentlemen, as to the fundamental principles of religion and morals, and again as to the fundamental principles of Christianity, or what are called the dogmas of faith,—as to this double creed, natural and revealed,—we, none of us, should say that it is any shackle at all upon the intellect to maintain these inviolate. Indeed, a Catholic cannot put off his thought of them; and they as little impede the movements of his intellect as the laws of physics impede his bodily movements. The habitual apprehension of them has become a second nature with him, as the laws of optics, hydrostatics, dynamics, are latent conditions which he takes for granted in the use of his corporeal organs. I am not supposing any collision with dogma, I am but speaking of opinions of divines, or of the multitude, parallel to those in former times of the sun going round the earth, or of the last day being close at hand, or of St. Dionysius the Areopagite being the author of the works which bear his name.

Nor, secondly, even as regards such opinions, am I supposing any direct intrusion into the province of religion, or of a teacher of Science actually laying down the law _in a matter of Religion_; but of such unintentional collisions as are incidental to a discussion pursued on some subject of his own. It would be a great mistake in such a one to propose his philosophical or historical conclusions as the formal interpretation of the sacred text, as Galileo is said to have done, instead of being content to hold his doctrine of the motion of the earth as a scientific conclusion, and leaving it to those whom it really concerned to compare it with Scripture. And, it must be confessed, Gentlemen, not a few instances occur of this mistake at the present day, on the part, not indeed of men of science, but of religious men, who, from a nervous impatience lest Scripture should for one moment seem inconsistent with the results of some speculation of the hour, are ever proposing geological or ethnological comments upon it, which they have to alter or obliterate before the ink is well dry, from changes in the progressive science, which they have so officiously brought to its aid.

And thirdly, I observe that, when I advocate the independence of philosophical thought, I am not speaking of any _formal teaching_ at all, but of investigations, speculations, and discussions. I am far indeed from allowing, in any matter which even borders on Religion, what an eminent Protestant divine has advocated on the most sacred subjects,—I mean “the liberty of Prophesying.” I have no wish to degrade the professors of Science, who ought to be Prophets of the Truth, into mere advertisers of crude fancies or notorious absurdities. I am not pleading that they should at random shower down upon their hearers ingenuities and novelties; or that they should teach even what has a basis of truth in it, in a brilliant, off-hand way, to a collection of youths, who may not perhaps hear them for six consecutive lectures, and who will carry away with them into the country a misty idea of the half-created theories of some ambitious intellect.

Once more, as the last sentence suggests, there must be great care taken to avoid scandal, or shocking the popular mind, or unsettling the weak; the association between truth and error being so strong in particular minds that it is impossible to weed them of the error without rooting up the wheat with it. If, then, there is the chance of any current religious opinion being in any way compromised in the course of a scientific investigation, this would be a reason for conducting it, not in light ephemeral publications, which come into the hands of the careless or ignorant, but in works of a grave and business-like character, answering to the medieval schools of philosophical disputation, which, removed as they were from the region of popular thought and feeling, have, by their vigorous restlessness of inquiry, in spite of their extravagances, done so much for theological precision.

7.
I am not, then, supposing the scientific investigator (1) to be _coming into collision with dogma_; nor (2) venturing, by means of his investigations, upon any interpretation of _Scripture_, or upon other conclusion _in the matter of religion_; nor (3) of his _teaching_, even in his own science, religious parodoxes, when he should be investigating and proposing; nor (4) of his recklessly _scandalizing the weak_; but, these explanations being made, I still say that a scientific speculator or inquirer is not bound, in conducting his researches, to be every moment adjusting his course by the maxims of the schools or by popular traditions, or by those of any other science distinct from his own, or to be ever narrowly watching what those external sciences have to say to him, or to be determined to be edifying, or to be ever answering heretics and unbelievers; being confident, from the impulse of a generous faith, that, however his line of investigation may swerve now and then, and vary to and fro in its course, or threaten momentary collision or embarrassment with any other department of knowledge, theological or not, yet, if he lets it alone, it will be sure to come home, because truth never can really be contrary to truth, and because often what at first sight is an “exceptio,” in the event most emphatically “probat regulam.”

This is a point of serious importance to him. Unless he is at liberty to investigate on the basis, and according to the peculiarities, of his science, he cannot investigate at all. It is the very law of the human mind in its inquiry after and acquisition of truth to make its advances by a process which consists of many stages, and is circuitous. There are no short cuts to knowledge; nor does the road to it always lie in the direction in which it terminates, nor are we able to see the end on starting. It may often seem to be diverging from a goal into which it will soon run without effort, if we are but patient and resolute in following it out; and, as we are told in Ethics to gain the mean merely by receding from both extremes, so in scientific researches error may be said, without a paradox, to be in some instances the way to truth, and the only way. Moreover, it is not often the fortune of any one man to live through an investigation; the process is one of not only many stages, but of many minds. What one begins another finishes; and a true conclusion is at length worked out by the co-operation of independent schools and the perseverance of successive generations. This being the case, we are obliged, under circumstances, to bear for a while with what we feel to be error, in consideration of the truth in which it is eventually to issue.

The analogy of locomotion is most pertinent here. No one can go straight up a mountain; no sailing vessel makes for its port without tacking. And so, applying the illustration, we can indeed, if we will, refuse to allow of investigation or research altogether; but, if we invite reason to take its place in our schools, we must let reason have fair and full play. If we reason, we must submit to the conditions of reason. We cannot use it by halves; we must use it as proceeding from Him who has also given us Revelation; and to be ever interrupting its processes, and diverting its attention by objections brought from a higher knowledge, is parallel to a landsman’s dismay at the changes in the course of a vessel on which he has deliberately embarked, and argues surely some distrust either in the powers of Reason on the one hand, or the certainty of Revealed Truth on the other. The passenger should not have embarked at all, if he did not reckon on the chance of a rough sea, of currents, of wind and tide, of rocks and shoals; and we should act more wisely in discountenancing altogether the exercise of Reason than in being alarmed and impatient under the suspense, delay, and anxiety which, from the nature of the case, may be found to attach to it. Let us eschew secular history, and science, and philosophy for good and all, if we are not allowed to be sure that Revelation is so true that the altercations and perplexities of human opinion cannot really or eventually injure its authority. That is no intellectual triumph of any truth of Religion, which has not been preceded by a full statement of what can be said against it; it is but the ego vapulando, ille verberando, of the Comedy.

Great minds need elbow-room, not indeed in the domain of faith, but of thought. And so indeed do lesser minds, and all minds. There are many persons in the world who are called, and with a great deal of truth, geniuses. They had been gifted by nature with some particular faculty or capacity; and, while vehemently excited and imperiously ruled by it, they are blind to everything else. They are enthusiasts in their own line, and are simply dead to the beauty of any line _except_ their own. Accordingly, they think their own line the only line in the whole world worth pursuing, and they feel a sort of contempt for such studies as move upon any other line. Now, these men may be, and often are, very good Catholics, and have not a dream of any thing but affection and deference towards Catholicity, nay, perhaps are zealous in its interests. Yet, if you insist that in their speculations, researches, or conclusions in their particular science, it is not enough that they should submit to the Church generally, and acknowledge its dogmas, but that they must get up all that divines have said or the multitude believed upon religious matters, you simply crush and stamp out the flame within them, and they can do nothing at all.

This is the case of men of genius: now one word on the contrary in behalf of master minds, gifted with a broad philosophical view of things, and a creative power, and a versatility capable of accommodating itself to various provinces of thought. These persons perhaps, like those I have already spoken of, take up some idea and are intent upon it;—some deep, prolific, eventful idea, which grows upon them, till they develop it into a great system. Now, if any such thinker starts from radically unsound principles, or aims at directly false conclusions, if he be a Hobbes, or a Shaftesbury, or a Hume, or a Bentham, then, of course, there is an end of the whole matter. He is an opponent of Revealed Truth, and he means to be so;—nothing more need be said. But perhaps it is not so; perhaps his errors are those which are inseparable accidents of his system or of his mind, and are spontaneously evolved, not pertinaciously defended. Every human system, every human writer, is open to just criticism. Make him shut up his portfolio; good! and then perhaps you lose what, on the whole and in spite of incidental mistakes, would have been one of the ablest defences of Revealed Truth (directly or indirectly, according to his subject) ever given to the world.

This is how I should account for a circumstance, which has sometimes caused surprise, that so many great Catholic thinkers have in some points or other incurred the criticism or animadversion of theologians or of ecclesiastical authority. It must be so in the nature of things; there is indeed an animadversion which implies a condemnation of the author; but there is another which means not much more than the "piè legendum" written against passages in the Fathers. The author may not be to blame; yet the ecclesiastical authority would be to blame, if it did not give notice of his imperfections. I do not know what Catholic would not hold the name of Malebranche in veneration;(48) but he may have accidentally come into collision with theologians, or made temerarious assertions, notwithstanding.

The practical question is, whether he had not much better have written as he has written, than not have written at all. And so fully is the Holy See accustomed to enter into this view of the matter, that it has allowed of its application, not only to philosophical, but even to theological and ecclesiastical authors, who do not come within the range of these remarks. I believe I am right in saying that, in the case of three great names, in various departments of learning, Cardinal Noris, Bossuet, and Muratori,(49) while not concealing its sense of their having propounded each what might have been said better, nevertheless it has considered, that their services to Religion were on the whole far too important to allow of their being molested by critical observation in detail.

And now, Gentlemen, I bring these remarks to a conclusion. What I would urge upon every one, whatever may be his particular line of research,—what I would urge upon men of Science in their thoughts of Theology,—what I would venture to recommend to theologians, when their attention is drawn to the subject of scientific investigations,—is a great and firm belief in the sovereignty of Truth. Error may flourish for a time, but Truth will prevail in the end. The only effect of error ultimately is to promote Truth. Theories, speculations, hypotheses, are started; perhaps they are to die, still not before they have suggested ideas better than themselves. These better ideas are taken up in turn by other men, and, if they do not yet lead to truth, nevertheless they lead to what is still nearer to truth than themselves; and thus knowledge on the whole makes progress. The errors of some minds in scientific investigation are more fruitful than the truths of others. A Science seems making no progress, but to abound in failures, yet imperceptibly all the time it is advancing, and it is of course a gain to truth even to have learned what is not true, if nothing more.

On the other hand, it must be of course remembered, Gentlemen, that I am supposing all along good faith, honest intentions, a loyal Catholic spirit, and a deep sense of responsibility. I am supposing, in the scientific inquirer, a due fear of giving scandal, of seeming to countenance views which he does not really countenance, and of siding with parties from whom he heartily differs. I am supposing that he is fully alive to the existence and the power of the infidelity of the age; that he keeps in mind the moral weakness and the intellectual confusion of the majority of men; and that he has no wish at all that any one soul should get harm from certain speculations to-day, though he may have the satisfaction of being sure that those speculations will, as far as they are erroneous or misunderstood, be corrected in the course of the next half-century.
