To scientific men this is so evident that they are unable to imagine what the world looks like to other people. They cannot realise that by a majority of even the educated classes the phenomena of nature and the affairs of mankind are still seen through the old screens of mystery and superstition. The man of science regards nature as in great and ever increasing measure a soluble problem. For the layman such inquiries are either indifferent and somewhat absurd, or, if they attract his attention at all, are interesting only as possible sources of profit. I suspect that the distinction between these two classes of mind is not to any great degree a product of education.
It is contemporary commonplace that if science were more prominent in our educational system everybody would learn it and things would come all right. That interest in science would be extended is probable. There is in the population a residuum of which we will speak later, who would profit by the opportunity; but that the congenitally unscientific, the section from which the heads of government temporal and spiritual, the lawyers, administrators, politicians, the classes upon whose minds the public life of this country almost wholly depends, would by imbibition of scientific diet at any period of life, however early, be essentially altered seems in a high degree unlikely. Of the converse case we have long experience, and I would ask those who entertain such sanguine expectations, whether the results of administering literature to scientific boys give much encouragement to their views. This consideration brings us to the one hard, physiological fact that should form the foundation of all educational schemes: the congenital diversity of the individual types. Education has too long been regarded as a kind of cookery: put in such and such ingredients in given proportions and a definite product will emerge. But living things have not the uniformity which this theory of education assumes. Our population is a medley of many kinds which will continue heterogeneous, to whatever system of education they are submitted, just as various types of animals maintain their several characteristics though nourished on identical food, or as you may see various sorts of apples remaining perfectly distinct though grafted on the same stock. Their diversity is congenital.
According to the proposal of the reformers the natural sciences should be universally taught and be given "capital importance" in the examinations for the government services, but, cordially as we may approve the suggestion, we ought to consider what exactly its adoption is likely to effect. The intention of the proposal is doubtless that our public servants, especially the highest of them, shall, while preserving the great qualities they now possess, add also a knowledge of science and especially scientific habits of mind. Such is the "ample proposition that hope makes." Does experience of men accord with it at all? Education, whether we like it or not, is a selective agency. I doubt whether the change proposed will sensibly alter the characters of the group on whom our choice at present falls. Rather, if forced upon an unwilling community, must it act by substituting another group. The most probable result would not be that the type of men who now fill great positions would become scientific, but rather that their places would be taken by men of an altogether distinct mental type. At the present time these two types of men meet but little. They scarcely know each other. Their differences are profound, affecting thoughts, ways of looking at things, and mental interests of every kind. If either could for a moment see the world with the vision of the other he would be amazed, but to do so he would need at least to be born again, and probably, as Samuel Butler remarked, of different parents. No doubt the abler man of either type could learn with more or less effort or unreadiness the subject-matter and principles of the other's business, but any one who has watched the habits of the two classes will perceive that for them in any real sense to exchange interests, or that either should adopt the scheme of proportion which the other assigns to the events of nature and of life, a metamorphosis well nigh miraculous must be presupposed.
The Bishop of London speaking lately on behalf of the National Mission said that nature helped him to believe in God, and as evidence for his belief referred to the fact that we are not "blown off" this earth as it rushes through space, declaring that this catastrophe had been averted because "Some one" had wrapped seventy miles of atmosphere round our planet[[2]]. Does any one think that the Bishop's slip was in fact due to want of scientific teaching at Marlborough? His chances of knowing about Sir Isaac Newton, etc., etc., have been as good as those of many familiar with the accepted version. I would rather suppose that such sublunary problems had not interested him in the least, and that he no more cared how we happen to stick on the earth's surface than St Paul cared how a grain of wheat or any other seed germinates beneath it, when he similarly was betrayed into an unfortunate illustration.
So too on the famous occasion—always cited in these debates—when a Home Secretary defended the Government for having permitted the importation of fats into Germany on the ground that the discovery that glycerine could be made from fat was a recent advance in chemistry, he was not showing the defects of a literary education so much as a want of interest in the problems of nature, and the subject-matter of science at large. It is to be presumed indeed that neither fats, nor glycerine, nor the dependent problem how living bodies are related to the world they inhabit, had ever before seemed to him interesting. Nor can we suppose they would, even if chemistry were substituted for Greek in Responsions.
The difficulty in obtaining full recognition for science lies deeper than this. It is a part of public opinion or taste which may well survive changes in the educational system. Blunders about science like those illustrated above are soon excused. Few think much the worse of the perpetrators, whereas a corresponding obliviousness to language, history, literature, and indeed to learning other than their own which we of the scientific fraternity have agreed to condone in our members is incompatible with public life of a high order. Both classes have their disabilities. That of the scientific side is well expressed in an incident which befell the late Professor Hales. Examining in the Little-Go viva voce, he asked a candidate, with reference to some line in a Greek play, what passage in Shakespeare it recalled to him, and received the answer "Please, sir, I am a mathematical man." Some, no doubt, would rather ignore gravitation. When, for example, one hears, as I did not long since, several scientific students own in perfect sincerity that they could not recall anything about Ananias and Sapphira and another, more enlightened, say that he was sure Ananias was a name for a liar though he could not tell why, one is driven to admit that ignorance of this special but not uncommon kind does imply more than inability to remember an old legend. We may be reluctant to confess the fact, but though most scientific men have some recreation, often even artistic in nature, we have with rare exceptions withdrawn from the world in which letters, history and the arts have immediate value, and simple allusions to these topics find us wanting. Of the two kinds of disability which is the more grave? Truly gross ignorance of science darkens more of a man's mental horizon, and in its possible bearing on the destinies of a race is far more dangerous than even total blindness to the course of human history and endeavour; and yet it is difficult to question the popular verdict that to know nothing of gravitation though ridiculous is venial, while to know nothing of Ananias is an offence which can never be forgiven.
That is the real difficulty. The people of this country have definitely preferred the unscientific type, holding the other virtually in contempt. Their choice may be right or wrong, but that it is reversible seems unlikely. Such revolutions in public opinion are rare events. Democracy moreover inevitably worships and is swayed by the spoken word. As inevitably, the range and purposes of science daily more and more transcend the comprehension—even the educated comprehension—of the vulgar, who will of course elevate the nimble and versatile, speaking a familiar language, above dull and inarticulate natural philosophers.
In these discussions there is a disposition to forget how very largely natural science is already included in the educational curriculum both at schools and universities. Schools subsidised by the Board of Education are obliged to provide science-teaching. The public schools have equipment, in some cases a superb equipment, for teaching at least physics and chemistry. At the newer universities there are great and vigorous schools of science. Of the old universities Cambridge stands out as a chief centre of scientific activity. In several branches of science Cambridge is without question pre-eminent. The endowments both of the university and the colleges are freely used for the advancement of the sciences. Not only in these material ways are scientific studies in no sense neglected, but the position of the sciences is recognised and even envied by those who follow other kinds of learning. The scientific schools of Cambridge form perhaps the dominant force among the resident body of the university, and except by virtue of some great increase in the endowments, it would be impossible to extend further the scientific side of Cambridge and still maintain other forms of intellectual activity in such proportion as to preserve that healthy co-ordination which is the life of a great university.
At Oxford the case is no doubt very different. The measure in which the sciences are esteemed appears only too plainly in the small proportion of Fellowships filled by men of science. Progress has nevertheless begun. At the remarkable Conference called in May, 1916, to protest against the neglect of science it was noticeable that the speakers were, in overwhelming majority, Oxford men[[3]].
