all busily welding an empire together in a marvellous framework of citizenship, manners, and laws, that laid assured foundations for a still higher civilisation that was to come after. He will learn how when the Roman Empire declined, then at Damascus and Bagdad and Seville the Mahometan conquerors took up the torch of science and learning, and handed it on to western Europe when the new generations were ready. He will learn how in the meantime, during ages which we both wrongly and ungratefully call dark, from Rome again, that other great organisation, the mediæval Church, had arisen, which amid many imperfections and some crimes did a work that no glory of physical science can equal, and no instrument of physical science can compass, in purifying men's appetites, in setting discipline and direction on their lives, and in offering to humanity new types of moral obligation and fairer ideals of saintly perfection, whose light still shines like a star to guide our own poor voyages. It is only by this contemplation of the life of our race as a whole that men see the beginnings and the ends of things; learn not to be near-sighted in history, but to look before and after; see their own part and lot in the rising up and going down of empires and faiths since first recorded time began; and what I am contending for is that even if you can take your young men and women no farther than the mere vestibule of this ancient and ever venerable Temple of many marvels, you will have opened to them the way to a kind of knowledge that not only enlightens the understanding, but enriches the character—which is a higher thing than mere intellect—and makes it constantly alive with the spirit of beneficence.

I know it is said that such a view of collective history is true, but that you will never get plain people to respond to it; it is a thing for intellectual dilettanti and moralising virtuosi. Well, we do not know, because we have never yet honestly tried, what the commonest people will or will not respond to. When Sir Richard Wallace's pictures were being exhibited at Bethnal Green, after people had said that the workers had no souls for art and would not appreciate its treasures, a story is told of a female in very poor clothes gazing intently at a picture of the Infant Jesus in the arms of his Mother, and then exclaiming, 'Who would not try to be a good woman, who had such a child as that?' We have never yet, I say, tried the height and pitch to which our people are capable of rising.

I have thought it well to take this opportunity of saying a word for history, because I cannot help thinking that one of the most narrow, and what will eventually be one of the most impoverishing, characteristics of our day is the excessive supremacy claimed for physical science. This is partly due, no doubt, to a most wholesome reaction against the excessive supremacy that has hitherto been claimed for literature, and held by literature, in our schools and universities. At the same time, it is well to remember that the historic sciences are making strides not unworthy of being compared with those of the physical sciences, and not only is there room for both, but any system is radically wrong which excludes or depresses either to the advantage of the other.[[2]]

And now there is another idea which I should like to throw out, if you will not think it too tedious and too special. It is an old saying that, after all, the great end and aim of the British Constitution is to get twelve honest men into a box. That is really a very sensible way of putting the theory, that the first end of government is to give security to life and property, and to make people keep their contracts. But with this view it is not only important that you should get twelve honest men into a box: the twelve honest men must have in their heads some notions as to what constitutes Evidence. Now it is surely a striking thing that while we are so careful to teach physical science and literature; while men want to be endowed in order to have leisure to explore our spinal cords, and to observe the locomotor system of Medusæ—and I have no objection against those who urge on all these studies—yet there is no systematic teaching, very often no teaching at all, in the principles of Evidence and Reasoning, even for the bulk of those who would be very much offended if we were to say that they are not educated. Of course I use the term evidence in a wider sense than the testimony in crimes and contracts, and the other business of courts of law. Questions of evidence are rising at every hour of the day. As Bentham says, it is a question of evidence with the cook whether the joint of meat is roasted enough. It has been excellently said that the principal and most characteristic difference between one human intellect and another consists in their ability to judge correctly of evidence. Most of us, Mr. Mill says, are very unsafe hands at estimating evidence, if appeal cannot be made to actual eyesight. Indeed, if we think of some of the tales that have been lately diverting the British Association, we might perhaps go farther, and describe many of us as very bad hands at estimating evidence, even where appeal can be made to actual eyesight. Eyesight, in fact, is the least part of the matter. The senses are as often the tools as the guides of reason. One of the longest chapters in the history of vulgar error would contain the cases in which the eyes have only seen what old prepossessions inspired them to see, and were blind to all that would have been fatal to the prepossessions. 'It is beyond all question or dispute,' says Voltaire, 'that magic words and ceremonies are quite capable of most effectually destroying a whole flock of sheep, if the words be accompanied by a sufficient quantity of arsenic.' Sorcery has no doubt been exploded—at least we assume that it has—but the temper that made men attribute all the efficacy to the magic words, and entirely overlook the arsenic, still prevails in a great host of moral and political affairs, into which it is not convenient to enter here. The stability of a government, for instance, is constantly set down to some ornamental part of it, when in fact the ornamental part has no more to do with stability than the incantations of the soothsayer.

You have heard, again, that for many generations the people of the Isle of St. Kilda believed that the arrival of a ship in the harbour inflicted on the islanders epidemic colds in the head, and many ingenious reasons were from time to time devised by clever men why the ship should cause colds among the population. At last it occurred to somebody that the ship might not be the cause of the colds, but that both might be the common effects of some other cause, and it was then remembered that a ship could only enter the harbour when there was a strong north-east wind blowing.

However faithful the observation, as soon as ever a man uses words he may begin at that moment to go wrong. 'A village apothecary,' it has been said, 'and if possible in a still greater degree, an experienced nurse, is seldom able to describe the plainest case without employing a phraseology of which every word is a theory; the simplest narrative of the most illiterate observer involves more or less of hypothesis;'—yet both by the observer himself and by most of those who listen to him, each of these conjectural assumptions is treated as respectfully as if it were an established axiom. We are supposed to deny the possibility of a circumstance, when in truth we only deny the evidence alleged for it. We allow the excellence of reasoning from certain data to captivate our belief in the truth of the data themselves, even when they are unproved and unprovable. There is no end, in short, of the ways in which men habitually go wrong in their reasoning, tacit or expressed. The greatest boon that any benefactor could confer on the human race would be to teach men—and especially women—to quantify their propositions. It sometimes seems as if Swift were right when he said that Mankind were just as fit for flying as for thinking.

Now it is quite true that mother-wit and the common experiences of life do often furnish people with a sort of shrewd and sound judgment that carries them very creditably through the world. They come to good conclusions, though perhaps they would give bad reasons for them, if they were forced to find their reasons. But you cannot count upon mother-wit in everybody; perhaps not even in a majority. And then as for the experience of life,—there are a great many questions, and those of the deepest ultimate importance to mankind, in which the ordinary experience of life sheds no light, until it has been interrogated and interpreted by men with trained minds. 'It is far easier,' as has been said, 'to acquire facts than to judge what they prove.' What is done in our systems of training to teach people how to judge what facts prove? There is Mathematics, no doubt; anybody who has done even no more than the first book of Euclid's geometry, ought to have got into his head the notion of a demonstration, of the rigorously close connection between a conclusion and its premisses, of the necessity of being able to show how each link in the chain comes to be where it is, and that it has a right to be there. This, however, is a long way from the facts of real life, and a man might well be a great geometer, and still be a thoroughly bad reasoner in practical questions.

Again, in other of your classes, in Chemistry, in Astronomy, in Natural History, besides acquiring groups of facts, the student has a glimpse of the method by which they were discovered, of the type of inference to which the discovery conforms, so that the discovery of a new comet, the detection of a new species, the invention of a new chemical compound, each becomes a lesson of the most beautiful and impressive kind in the art of reasoning. And it would be superfluous and impertinent for me here to point out how valuable such lessons are in the way of mental discipline, apart from the fruit they bear in other ways. But here again the relation to the judgments we have to form in the moral, political, practical sphere, is too remote and too indirect. The judgments, in this region, of the most brilliant and successful explorers in physical science, seem to be exactly as liable to every kind of fallacy as those of other people. The application of scientific method and conception to society is yet in its infancy, and the Novum Organum or the Principia of moral and social phenomena will perhaps not be wholly disclosed to any of us now alive. In any case it is clear that for the purposes of such an institution as this, if the rules of evidence and proof and all the other safeguards for making your propositions true and relevant, are to be taught at all, they must be taught not only in an elementary form, but with illustrations that shall convey their own direct reference and application to practical life. If everybody could find time to master Mill's Logic or so instructive and interesting a book as Professor Jevons's Principles of Science, a certain number at any rate of the bad mental habits of people would be cured; and for those of you here who have leisure enough, and want to find a worthy keystone of your culture, it would be hard to find a better thing to do for the next six months than to work through one or both of the books I have just named—pen in hand. The ordinary text-books of formal logic do not seem to meet the special aim which I am now trying to impress as desirable—namely, the habit of valuing, not merely speculative nor scientific truth, but the truth of practical life; a practising of the intellect in forming and expressing the opinions and judgments that form the staple of our daily discourse.

It is now accepted that the most effective way of learning a foreign language is to begin by reading books written in it, or by conversing in it—and then after a certain empirical familiarity with vocabulary and construction has been acquired, one may proceed to master the grammar. Just in the same way it would seem to be the best plan to approach the art of practical reasoning in concrete examples, in cases of actual occurrence and living interest; and then after the processes of disentangling a complex group of propositions, of dividing and shifting, of scenting a fallacy, have all become familiar, it may be worth while to find names for them all, and to set out rules for reasoning rightly, just as in the former illustration the rules of writing correctly follow a certain practice rather than precede it.

Now it has long seemed to me that the best way of teaching carefulness and precision in dealing with propositions might be found through the medium of the argumentation in the courts of justice. This is reasoning in real matter. There is a famous book well known to legal students—Smith's Leading Cases—which contains a selection of important decisions, and sets forth the grounds on which the courts arrived at them. I have often thought that a dozen or a score of cases might be collected from this book into a small volume, that would make such a manual as no other matter could, for opening plain men's eyes to the logical pitfalls among which they go stumbling and crashing, when they think they are disputing like Socrates or reasoning like Newton. They would see how a proposition or an expression that looks straightforward and unmistakable, is yet on examination found to be capable of bearing several distinct interpretations and meaning several distinct things; how the same evidence may warrant different conclusions, and what kinds of evidence carry with them what degrees of validity: how certain sorts of facts can only be proved in one way, and certain other sorts of facts in some other way: how necessary it is, before you set out, to know exactly what it is you intend to show, or what it is you intend to dispute; how there may be many argumentative objections to a proposition, yet the balance be in favour of its adoption. It is from the generality of people having neglected to practise the attention on these and the like matters, that interest and prejudice find so ready an instrument of sophistry in that very art of speech which ought to be the organ of reason and truth. To bring the matter to a point, then, I submit that it might be worth while in this and all such institutions to have a class for the study of Logic, Reasoning, Evidence, and that such a class might well find its best material in selections from Leading Cases, and from Bentham's Rationale of Judicial Evidence, elucidated by those special sections in Mill's Logic, or smaller manuals such as those of Mr. Fowler, the Oxford Professor of Logic, which treat of the department of Fallacies. Perhaps Bentham's Book of Fallacies is too political for me to commend it to you here. But if there happens to be any one in Birmingham who is fond of meeting proposed changes by saying that they are Utopian; that they are good in theory, but bad in practice; that they are too good to be realised, and so forth, then I can promise him that he will in that book hear of something very much to his advantage.[[3]]
