Science and Morals and Other Essays Part 4

Another extremely curious fact is that another distinguished man of science, who lived three hundred years later than Fallopius and had all the knowledge which had acc.u.mulated during that prolific period to a.s.sist him, the late Philip Gosse, fell into the same pit as Fallopius.

As his son tells us, he wrote a book to prove that when the sudden act of creation took place the world came into existence so constructed as to bear the appearance of a place which had for aeons been inhabited by living things, or, as some of his critics unkindly put it, "that G.o.d hid the fossils in the rocks in order to tempt geologists into infidelity."

Gosse had the real answer under his eyes which Fallopius had not, for the riddle was unread in the latter's days. Yet Gosse's really unpardonable mistake was attributed to himself alone, and "Plymouth Brethrenism," which was the sect to which he belonged, was not saddled with it, nor have the Brethren been called obscurantists because of it.

Of course there is a second string to the accusation we are dealing with. If the scientific man did really express new and perhaps startling opinions, they would have been much newer and much more startling had he not held himself in for fear of the Church and said only about half of what he might have said. It is the half instead of the whole loaf of the former accusation. Thus, in its notice of Stensen, the current issue of the _Encyclopaedia Britannica_ says: "Cautiously at first, for fear of offending orthodox opinion, but afterwards more boldly, he proclaimed his opinion that these objects (_viz._ fossils) had once been parts of living animals."

One may feel quite certain that if Stensen had not been a Catholic ecclesiastic this notice would have run--and far more truthfully--"Cautiously at first, until he felt that the facts at his disposal made his position quite secure, and then more boldly, etc.

etc."

What in the ordinary man of science is caution, becomes cowardice in the Catholic. We shall find another example of this in the case of Buffon (1707-1788) often cited as that of a man who believed all that Darwin believed and one hundred years before Darwin, and who yet was afraid to say it because of the Church to which he belonged. This mistake is partly due to that lamentable ignorance of Catholic teaching, not to say that lamentable incapacity for clear thinking, on these matters, which afflicts some non-Catholic writers. Let us take an example from an eminently fairly written book, in which, dealing with Buffon, the author says: "I cannot agree with those who think that Buffon was an out-and-out evolutionist, who concealed his opinions for fear of the Church. No doubt he did trim his sails--the palpably insincere _Mais non, il est certain par la revelation que tous les animaux ont egalement participe a la grace de la creation_, following hard upon the too bold hypothesis of the origin of all species from a single one, is proof of it." Of course it is nothing of the kind, for, whatever Buffon may have meant, and none but himself could tell us, it is perfectly clear that whether creation was mediate (as under transformism considered from a Christian point of view it would be) or immediate, every created thing would partic.i.p.ate in the grace of creation, which is just the point which the writer from whom the quotation has been made has missed.

The same writer furnishes us with the real explanation of Buffon's att.i.tude when he says that Buffon was "too sane and matter-of-fact a thinker to go much beyond his facts, and his evolution doctrine remained always tentative." Buffon, like many another man, from St. Augustine down to his own times, considered the transformist explanation of living nature. He saw that it unified and simplified the conceptions of species and that there were certain facts which seemed strongly to support it.

But he does not seem to have thought that they were sufficient to establish it and he puts forward his views in the tentative manner which has just been suggested.

The fact is that those who father the accusations with which we have been dealing either do not know, or scrupulously conceal their knowledge, that what they proclaim to be scientific cowardice is really scientific caution, a thing to be lauded and not to be decried.

Let us turn to apply the considerations with which we have been concerned to the case of Galileo, to which generally misunderstood affair we must very briefly allude, since it is the standby of anti-Catholic controversialists. Monsignor Benson, in connection with the quotation recently cited, proclaimed himself "a violent defender of the Cardinals against Galileo." Perhaps no one will be surprised at his att.i.tude, but those who are not familiar with his _Life and Letters_ will certainly be surprised to learn that Huxley, after examining into the question, "arrived at the conclusion that the Pope and the College of Cardinals had rather the best of it."[28]

None the less it is the stock argument. Father Hull, S. J., whose admirable, outspoken, and impartial study of the case[29] should be on everybody's bookshelves, freely admits that the Roman Congregations made a mistake in this matter and thus takes up a less favourable position towards them than even the violently anti-Catholic Huxley.

No one will deny that the action of the Congregation was due to a desire to prevent simple persons from having their faith upset by a theory which seemed at the time to contradict the teaching of the Bible.

Remember that it was only a theory and that, when it was put forward, and indeed for many years afterwards, it was not only a theory, but one supported by no sufficient evidence. It was not in fact until many years after Galileo's death that final and convincing evidence as to the accuracy of his views was laid before the scientific world. There can be but little doubt that if Galileo had been content to discuss his theory with other men of science, and not to lay it down as a matter of proved fact--which, as we have seen, it was not--he would never have been condemned. Whilst we may admit, with Father Hull, that a mistake was made in this case, we may urge, with Cardinal Newman, that it is the only case in which such a thing has happened--surely a remarkable fact.

It is not for want of opportunities. Father Hull very properly cites various cases where a like difficulty might possibly have arisen, but where, as a matter of fact, it has not. For example, the geographical universality of the Deluge was at one time, and that not so very long ago, believed to be a.s.serted by the Bible; while, on the other hand, geologists seemed to be able to show, and in the event did show, that such a view was scientifically untenable. The attention of theologians having been called to this matter, and a further study made of pa.s.sages which until then had probably attracted but little notice, and quite certainly had never been considered from the new point of view, it became obvious that the meaning which had been attached to the pa.s.sages in question was not the necessary meaning, but on the contrary, a strained interpretation of the words. No public fuss having arisen about this particular difficulty, the whole matter was gradually and quietly disposed of. As Father Hull says, "the new view gradually filtered down from learned circles to the man in the street, so that nowadays the partiality of the Deluge is a matter of commonplace knowledge among all educated Christians, and is even taught to the rising generation in elementary schools."

In accordance with the wise provisions of the Encyclical _Providentissimus Deus_, with which all educated Catholics should make themselves familiar, conflicts have been avoided on this, and on other points, such as the general theory of evolution and the various problems connected with it; the antiquity of man upon the earth and other matters as to which science is still uncertain. Some of these points might seem to conflict with the Bible and the teachings of the Church.

As Catholics we can rest a.s.sured that the true explanation, whenever it emerges, cannot be opposed to the considered teaching of the Church.

What the Church does--and surely it must be clear that from her standpoint she could not do less--is to instruct Catholic men of science not to proclaim _as proved facts_ such modern theories--and there are many of them--as still remain wholly unproved, when these theories are such as might seem to conflict with the teaching of the Church. This is very far from saying that Catholics are forbidden to study such theories.

On the contrary, they are encouraged to do so, and that, need it be said, with the one idea of ascertaining the truth? Men of science, Catholic and otherwise, have, as a mere matter of fact, been time and again encouraged by Popes and other ecclesiastical authorities to go on searching for the truth, never, however, neglecting the wise maxim that all things must be proved. So long as a theory is unproved, it must be candidly admitted that it is a crime against science to proclaim it to be incontrovertible truth, yet this crime is being committed every day.

It is really against it that the _magisterium_ of the Church is exercised. The wholesome discipline which she exercises might also be exercised to the great benefit of the ordinary reading public by some central scientific authority, can such be imagined, endowed with the right to say (and in any way likely to be listened to): "Such and such a statement is interesting--even extremely interesting--but so far one must admit that no sufficient proof is forthcoming to establish it as a fact: it ought not, therefore, to be spoken of as other than a theory, nor proclaimed as fact."

Such constraint when rightly regarded is not or would not be a shackling of the human intellect, but a kindly and intelligent guidance of those unable to form a proper conclusion themselves. Such is the idea of the Church in the matter with which we have been dealing.

V. SCIENCE AND THE WAR

Amongst various important matters now brought to a sharper focus in the public eye, few, if any, require more careful attention than that which is concerned with science, its value, its position, its teachings, and how it should be taught. No one who has followed the domestic difficulties due to our neglect of the warnings of scientific men can fail to see how we have had to suffer because of the lax conduct of those responsible for these things in the past.

Within the first few weeks after the war broke out--to take one example--every medical man was the recipient of a doc.u.ment telling him of the expected shortage in a number of important drugs and suggesting the subst.i.tutes which he might employ. It was a timely warning; but it need never have been issued if we had not allowed the manufacture of drugs, and especially those of the so-called "synthetic" group, to drift almost entirely into the hands of the Badische Aniline Fabrik, and kindred firms in Germany. This difficulty, now partly overcome, is one which never would have arisen but for the deaf ear turned to the warnings of the scientific chemists. British pharmaceutical chemists, with one or two exceptions, had been relying upon foreign sources not only for synthetic drugs but actually for the raw materials of many of their preparations--such, for example, as aconite, belladonna, henbane, all of which can be freely grown--which even grow wild--in these islands; even, incredible as it may seem, for foxglove leaves. These things with many others were imported from Germany and Austria. Here again leeway has had to be made up; but it ought never to have been necessary, and now that the war is over steps should be taken to see that it never need be necessary again. The encouragement of British herb-gardens and of scientific experiment therein on the best method of culture for the raw material of our organic medicines must certainly be matters early taken in hand.

The cla.s.sical example of the mortal injury done to British manufacture by the British manufacturer's former contempt for the scientific man is that of the aniline dyes, which are so closely a.s.sociated with the synthetic drugs as to form one subject of discussion. Quite early in the war dye-stuffs ran short, and there was no means of replenishing the stock in Britain, nor even in America, these products having formed the staple of a colossal manufacture, with an enormous financial turnover, in Germany.

Let us look at the history of these dyes. The first aniline dye was discovered quite by accident, in 1856, by the late Professor W. H.

Perkin. He called it "mauve," from the French word for the mallow, the colour of whose flower it somewhat resembled. In 1862 there was an International Exhibition in London; and those who remembered it and its predecessor of 1851 have declared that the case of aniline dye-stuffs--for by that time quite a number of new pigments had been discovered--excited at the later the same attention as that given to the Koh-i-noor at the earlier. The invention, out of which grew the enormous German business already alluded to, and with which has been a.s.sociated the discovery and manufacture of the synthetic drugs, was entirely British in its inception and in its early stages. Moreover the raw materials on which it depended, namely, gas-tar products, were to be had in greater abundance in England than anywhere else. Yet, at the time when the war broke out, this industry had been allowed almost entirely to drift into German hands.

How was this? Let an expert reply. It was due, he tells us, to the neglect of "the repeated warnings which have been issued since that time" (_viz._ 1880, by which date the Germans had succeeded in capturing the trade in question) "in no uncertain voice by Meldola, Green, the Perkins (father and son), and many other English chemists." Further, he continues, two causes have invariably been indicated for the transfer of this industry to Germany--"first the neglect of organic chemistry in the Universities and colleges of this country" (a neglect which has long ceased), "and then the disregard by manufacturers of scientific methods and a.s.sistance and total indifference to the practice of research in connection with their processes and products." I remember talking some twenty-five years ago to a highly educated young student of Birmingham who was of German parentage though of English birth. He had just taken the degree of Doctor of Science in London University, and was on the eve of abandoning the adopted country of his parents for a position in the research laboratories of the Badische company, where he would be one among a number of chemists, running into hundreds, all engaged in research on gas-tar products. At that moment the great Birmingham gas-company was employing the services of one trained chemist.

Such was and is the neglect of science by business men. Could it have been otherwise, considering their bringing up? Let me again be reminiscent. I suppose the public school in England (not a Catholic school, for I was then a Protestant) at which I pursued what were described as studies did not in any very marked degree differ from its sister schools throughout the country. How was science encouraged there?

One hour per week, exactly one-fifth of the time devoted weekly, not to Greek and Latin (that would have been almost sacrilegious), but to the writing of Greek and Latin prose and alleged Greek and Latin verse--that was the amount of time which was devoted to what was called science. I suppose I had an ingrained vocation for science, for it was the only subject, except English composition, in which I ever felt interest at school. If the vocation had not been there, any interest in the subject must necessarily have been slain once for all in me, as I am sure it was in scores of others, by the way it was taught; for the instruction was confided to the ordinary form-master, who doled out his questions from a text-book perfunctorily used and probably heartily despised by a man brought up on strict cla.s.sical or mathematical lines. Our manufacturer is brought up in a school of this kind, and it would be a miracle if he emerged from it with any respect for science. Things have changed now, and for the better, as they have at most of the Universities; but we are dealing with the generation of manufacturers of my age who were largely responsible for the neglects now in question. Well, the boy left his school and went to Oxford or Cambridge, neither of which then greatly encouraged science. Its followers were, I believe, known as "Stinks Men." At any rate it is only comparatively recently that we have seen the splendid developments of to-day in those ancient inst.i.tutions. One relic of the ancient days gives us an illuminating idea of how things used to be, just as a fossil shows us the environment of its day.[30]

Trinity College, Dublin, has fine provision for scientific teaching, and a highly competent staff to teach. But in its const.i.tution it shows the att.i.tude towards science which till lately informed the older Universities.

Trinity College has in its Fellowship system one of the most important series of pecuniary rewards perhaps in Europe, of an educational character. A man has only once to pa.s.s an examination, admittedly one of great severity and compet.i.tive in character, and thenceforward to go on living respectably and doing such duties as are committed to him, to be ensured an excellent and increasing income for life. How great the rewards are will be gathered from the fact that a distinguished occupant of one of these positions some years ago endeavoured--with complete success--to enforce on me the importance of the Fellowship examination by telling me that he had already received over 50,000 in emoluments as a result of his success. He has received a good deal more since, and I hope will continue to be the recipient of this shower of gold for many years to come.[31] No doubt much might be urged for this system, which was for a long time popular in China for the selection of Mandarins, and I am not criticising it here. What I want to emphasise is that the examination for these valuable positions is either cla.s.sical or mathematical, and there it ends. The greatest biologist in the world would have as much chance of a Fellowship as the ragged urchin in the street unless he could "settle Hoti's business" or elucidate [Greek: P]

or do other things of that kind. It is a luminous example of what was--must we say is?--thought of science in certain academic circles.

Of course it may be urged--I have actually heard it urged--that nothing is science save that which is treatable by mathematical methods. It was a kind of inverted M. Jourdain who used this argument, a gentleman who imagined himself to have been teaching science during a long life without ever having effected what he supposed to be his object. Then, again, our manufacturer, whose object in life is to make money, is naturally, perhaps even necessarily, affected by the kind of salaries which highly trained and highly eminent men of science receive by way of reward for their work. Few, if any, receive anything like the emoluments attaching to the position of County Court Judge, and I know of only one case in which a Professor's income, to the delight and envy of all the teaching profession, actually, for a few years, soared somewhat near the empyrean of a Puisne Judge's reward.

Perhaps this is not to be wondered at; for Parliament always contains many lawyers, and at the moment, I think, not a single scientific expert, at least among the Commons. This is not really a sordid argument, though it may appear so. The labourer, after all, is worthy of his hire; but in the scientific world it very, very seldom happens that the hire is worthy of the labourer. Even to this day there is plenty of truth in the description of the att.i.tude of Mr. Meagles towards Mr.

Doyce as detailed by the author of _Little Dorrit_. Perhaps that is partly because it is generally the man of business, and not the unhappy man of science, who gains the money produced by scientific discoveries.

These are often, if not usually, made by accident, and by a man on the track of something else, on the elucidation of which he is probably so intent that he cannot spare time for side-issues, very likely never even thinks of them. Sir James Dewar discovered the principle of the "Thermos flask" whilst he was working at the exceedingly difficult subject of the liquefaction of air. I hope Sir James had the prescience to patent his discovery, and reap the reward which was due to him; but, if he did, he is one amongst a thousand who never took this trouble and of whom _Sic vos non vobis_ might well be said. When Sabatier had shown the importance of combinations of hydrogen effected by what is known as a catalyst, numerous patents were taken out--by other people, of course--on which were founded very flourishing businesses. Sabatier profited by none of these--so I understand. He received a n.o.bel prize for his discoveries; but another hath his heritage.

Though science has not received any great encouragement, yet in spite of that--the cynic might say because of that--it has made amazing progress during the past half-century. Mr. Chesterton somewhere notes that "a time may easily come when we shall see the great outburst of science in the Nineteenth Century as something quite as splendid, brief, unique, and ultimately abandoned as the outburst of art at the Renaissance."

That, of course, may be so, but as to the outburst there can be no question, nor of its persistence to the present day. That also is surely a curious phenomenon; for, as regards most other things, we seem to be in the trough of the wave, and not merely in these islands but all over the civilised world. In Art, in Music, in Literature, in the Drama, it would be difficult to argue in favour of a pre-eminence, or even of an equality of the present age, comparing it with its predecessors.

Take the politicians of the world; it is perhaps difficult, even foolish, for us who are living with them to prophesy with any approximation of accuracy what the historian of a future day may say about them. He may sum them up as respectable, honest mediocrities trying to do their best under exceptionally difficult circ.u.mstances; he may put them lower; he may put them higher; he may differentiate between those of different nations; but there is little doubt that, with the exception of the American President, he will not be able to point to any one of the calibre of Pitt or of Bismarck or of the less severely tried Disraeli or Gladstone.

But just the reverse is the case in science, which has men of the very first rank living, working, and discovering to-day. There are indeed signs that even our Government is cognizant of this. The creation of a Department of Industrial Scientific Research, the provision of a substantial income for the same, the increase of research-grants to learned societies, these and other things show that some attempt will be made to recognise the value of science to the State. Further, the lesson seems to have gone home to some few at least that there is no difference between what have been absurdly called Pure and Applied Science, since so very many "Applied" discoveries--such as the "Thermos"--arose in the course of what certainly would have been described as "Pure" researches.

It is to the public advantage that every educated person should know something about science; nor is this by any means as big or difficult an achievement as some may imagine. It is not necessary to teach any very large number of persons very much about any particular science or group of sciences. What is really important is that people should imbibe some knowledge of scientific methods--of the meaning of science. This can be done from the study of quite a few fundamental propositions of any one science under a good teacher--a first essential. Any person thus educated will, for the remainder of his life, be able at least to understand what is meant by science and the scientific method of approaching a problem. He will not, like an educational troglodyte at a recent Conference, refuse to describe anything as science which is not capable of mathematical treatment, nor allude compendiously to physiological study as "the cutting up of frogs." In a word, he will be an educated man, which can no more be said of one ignorant of science than it can be of one whose mind has never experienced the softening influence of letters.

So far, everybody whose opinion counts seems to be agreed; but in any plea for an extended and improved teaching of science, certain points ought not to be left out of count. In the first place, science is not the key to all locks; there are many important things--some of the most important things in life--with which it has nothing whatever to do. It will be well to recall Mr. Balfour's words at the opening of the National Physical Laboratory: "Science depends on measurement, and things not measurable are therefore excluded, or tend to be excluded, from its attention. But Life and Beauty and Happiness are not measurable. If there could be a unit of happiness, politics might begin to be scientific." It follows that there are a number of subjects on which the scientific man is just as fit, or as unfit, to express an opinion as any other man. The intense preoccupation which serious scientific studies demand, may render the man who is engaged therein even less competent to express an opinion on alien subjects than one whose attention, less concentrated, has time to range over diverse fields of study. Readers of Darwin's _Life_ will remember his confession that he had lost all taste for music, art, and literature; that he "could not endure to read a line of poetry" and found Shakespeare "so intolerably dull that it nauseated" him; and finally, that his mind seemed "to have become a kind of machine for grinding general laws out of a large collection of facts."

Despite this warning as to the limits of science, we have no lack of instances of scientific men posing as authorities on subjects on which they had no real right to be heard, and, what is worse, being accepted as such by the uninstructed crowd. Thus Professor Huxley, who, as some one once said, "made science respectable," was wont to utter pontifical p.r.o.nouncements on the subject of Home Rule for Ireland. His knowledge of that country was quite rudimentary, and his visits to it had been as few and as brief as if he had been its Sovereign; but that did not prevent him from delivering judgment, nor unfortunately deter many from following that judgment as if it had been inspired. I am not now arguing as to the rights and wrongs of Huxley's view on the matter in question: I have my own opinion on that. What I am urging is that his position, whether as a zoologist or, incidentally, as a great master of the English language, in no way ent.i.tled him to express an opinion or rendered him a better authority on such a question than any casual fellow-traveller in a railway carriage might easily be.

This is bad enough; but what is far worse is when scientific experts on the strength of their study of Nature a.s.sume the right of uttering judicial p.r.o.nouncements on moral and sociological questions, judgments some at least of which are subversive of both decency and liberty. Thus we have lately been told that it is "wanton cruelty" to keep a weak or sickly child alive; and the medical man, under a reformed system of medical ethics, is to have leave and licence to put an end to its life in a painless manner. To what enormities and dastardly agreements this might lead need hardly be suggested; and I am quite confident that the members of the honourable profession of physic, to which I am proud to belong, have no desire whatever for such a reform of the law or of their ethics. Then we are told in the same address (Bateson, _British a.s.sociation Addresses in Australia_, 1914) that on the whole a decline in the birth-rate is rather a good thing, and that families averaging four children are quite enough to keep the world going comfortably. The date of this address will be noted; and the fact that the war, which was then just beginning, has probably caused its author and has caused everybody else to see the utter futility of such a.s.sertions.

However, if we are to rear only four children per marriage, and if we are to give the medical man liberty to weed out the weaklings, it behoves us to see that the children whom we produce are of the best quality. Let us, therefore, hie to the stud-farm, observe its methods and proceed to apply them to the human race. We must definitely prevent feeble-minded persons from propagating their species. Within limits, that is a proposition with which all instructed persons would agree, though few, we imagine, would put their opinions so uncharitably as the lecturer did: "The union of such social vermin we should no more permit than we would allow parasites to breed on our own bodies." But we must go farther than this, and introduce all sorts of restrictions on matrimony, until finally it comes to be a matter to be arranged under rigid laws by a jury of elderly persons--all, we may feel perfectly sure, "cranks" of the first water.

In what _milieu_ are their findings to take effect? It is very important to consider that. The author from whom I have been quoting tells us what we want to know. Man, he tells us, is "a rather long-lived animal, with great powers of enjoyment, if he does not deliberately forgo them." In the past, we are told, "superst.i.tious and mythical ideas of sin have predominantly controlled these powers." We have changed all that now; as the parent in _Punch_ says to the crying child by the seash.o.r.e, "You've come out to enjoy yourself, and enjoy yourself you shall!" So we are to plunge into the whirlpool of eugenic delights without any fear of that "bugbear of a h.e.l.l" which another writer congratulates us on getting rid of. We can, it appears, enter upon our eugenic experiment without a single moral scruple to restrain us or a single religious restriction to interfere with us. In this soil is the plant to be grown, and the first weed to be eradicated is that of the right of personal choice of a partner for life, or for such other term as the law under the new _regime_ may require. Jack is to be torn from weeping Jill, and handed over to reluctant Joan, to whom he is personally displeasing and for whom he has not the slightest desire, and handed over because the Breeding Committee think it is likely to prove advantageous for the Coming Race. All that may be possible--or may not--but what then? When you are carrying out Mendelian experiments on peas, you can enclose your flowers in muslin bags and prevent anything interfering with your observations. And in the stud-farm you can keep the occupants shut up.

But what are you going to do with Jack? and with Jill? And still more with Joan? They cannot be permanently isolated, neither are they restrained by any "mythical ideas of sin." They have been educated to the idea that their highest duty is to enjoy themselves. Why should they not do what they like? And consequently, as any reasoning person can see, "The Inevitable" must happen; and where is your experiment and where the Coming Race? It is perfectly useless for doctrinaires to argue, as doctrinaires will, about ethical restraints. Nature has _no_ ethical restraints; and any ethical restraints which man has come from that higher nature of his which he does not share with the lower creation. What those whom the late Mr. Devas so aptly called "after-Christians" always forget is that the humane, the Christian side of life, which they as well as others exhibit, is due to the influence, lingering if you like, of Christianity. They ignore or forget the pit out of which they were digged.
