So it is a sort of Rubicon. One goes across; or not. But if one does, there is no manner of security against miracles. One may be in for anything.

THE PROPRIETY OF MIRACLES
The Principle at the same moment that it explains the Rules supersedes them.
seeley, Ecce Homo, chap. xvi.
If the ultimate Fact is not an abstraction but the living God, opaque by the very fullness of His blinding actuality, then He might do things. He might work miracles. But would He? Many people of sincere piety feel that He would not. They think it unworthy of Him. It is petty and capricious tyrants who break their own laws: good and wise kings obey them. Only an incompetent workman will produce work which needs to be interfered with. And people who think in this way are not satisfied by the assurance given them in Chapter VIII that miracles do not, in fact, break the laws of Nature. That may be undeniable. But it will still be felt (and justly) that miracles interrupt the orderly march of events, the steady development of Nature according to her own inherent genius or character. That regular march seems to such critics as I have in mind more impressive than any miracle. Looking up (like Lucifer in Meredith’s sonnet) at the night sky, they feel it almost impious to suppose that God should sometimes unsay what He has once said with such magnificence. This feeling springs from deep and noble sources in the mind and must always be treated with respect. Yet it is, I believe, founded on an error.
When schoolboys begin to be taught to make Latin verses at school they are very properly forbidden to have what is technically called ‘a spondee in the fifth foot’. It is a good rule for boys because the normal hexameter does not have a spondee there: if boys were allowed to use this abnormal form they would be constantly doing it for convenience and might never get the typical music of the hexameter into their heads at all. But when the boys come to read Virgil they find that Virgil does the very thing they have been forbidden to do—not very often, but not so very rarely either. In the same way, young people who have just learned how to write English rhyming verse, may be shocked at finding ‘bad’ rhymes (i.e. half-rhymes) in the great poets. Even in carpentry or car-driving or surgery there are, I expect, ‘licenses’—abnormal ways of doing things—which the master will use himself both safely and judiciously but which he would think it unwise to teach his pupils.
Now one often finds that the beginner, who has just mastered the strict formal rules, is over-punctilious and pedantic about them. And the mere critic, who is never going to begin himself, may be more pedantic still. The classical critics were shocked at the ‘irregularity’ or ‘licenses’ of Shakespeare. A stupid schoolboy might think that the abnormal hexameters in Virgil, or the half-rhymes in English poets, were due to incompetence. In reality, of course, every one of them is there for a purpose and breaks the superficial regularity of the metre in obedience to a higher and subtler law: just as the irregularities in The Winter’s Tale do not impair, but embody and perfect, the inward unity of its spirit.
In other words, there are rules behind the rules, and a unity which is deeper than uniformity. A supreme workman will never break by one note or one syllable or one stroke of the brush the living and inward law of the work he is producing. But he will break without scruple any number of those superficial regularities and orthodoxies which little, unimaginative critics mistake for its laws. The extent to which one can distinguish a just ‘license’ from a mere botch or failure of unity depends on the extent to which one has grasped the real and inward significance of the work as a whole. If we had grasped as a whole the innermost spirit of that ‘work which God worketh from the beginning to the end’, and of which Nature is only a part and perhaps a small part, we should be in a position to decide whether miraculous interruptions of Nature’s history were mere improprieties unworthy of the Great Workman or expressions of the truest and deepest unity in His total work. In fact, of course, we are in no such position. The gap between God’s mind and ours must, on any view, be incalculably greater than the gap between Shakespeare’s mind and that of the most peddling critics of the old French school.
For who can suppose that God’s external act, seen from within, would be that same complexity of mathematical relations which Nature, scientifically studied, reveals? It is like thinking that a poet builds up his line out of those metrical feet into which we can analyse it, or that living speech takes grammar as its starting point. But the best illustration of all is Bergson’s. Let us suppose a race of people whose peculiar mental limitation compels them to regard a painting as something made up of little coloured dots which have been put together like a mosaic. Studying the brushwork of a great painting, through their magnifying glasses, they discover more and more complicated relations between the dots, and sort these relations out, with great toil, into certain regularities. Their labour will not be in vain. These regularities will in fact ‘work’; they will cover most of the facts. But if they go on to conclude that any departure from them would be unworthy of the painter, and an arbitrary breaking of his own rules, they will be far astray. For the regularities they have observed never were the rule the painter was following. What they painfully reconstruct from a million dots, arranged in an agonising complexity, he really produced with a single lightning-quick turn of the wrist, his eye meanwhile taking in the canvas as a whole and his mind obeying laws of composition which the observers, counting their dots, have not yet come within sight of, and perhaps never will. I do not say that the normalities of Nature are unreal. The living fountain of divine energy, solidified for purposes of this spatio-temporal Nature into bodies moving in space and time, and thence, by our abstract thought, turned into mathematical formulae, does in fact for us, commonly fall into such and such patterns. In finding out those patterns we are therefore gaining real, and often useful, knowledge. But to think that a disturbance of them would constitute a breach of the living rule and organic unity whereby God, from His own point of view, works, is a mistake. If miracles do occur then we may be sure that not to have wrought them would be the real inconsistency.
How a miracle can be no inconsistency, but the highest consistency, will be clear to those who have read Miss Dorothy Sayers’ indispensable book, The Mind of the Maker. Miss Sayers’ thesis is based on the analogy between God’s relation to the world, on the one hand, and an author’s relation to his book on the other. If you are writing a story, miracles or abnormal events may be bad art, or they may not. If, for example, you are writing an ordinary realistic novel and have got your characters into a hopeless muddle, it would be quite intolerable if you suddenly cut the knot and secured a happy ending by having a fortune left to the hero from an unexpected quarter. On the other hand there is nothing against taking as your subject from the outset the adventures of a man who inherits an unexpected fortune. The unusual event is perfectly permissible if it is what you are really writing about: it is an artistic crime if you simply drag it in by the heels to get yourself out of a hole. The ghost story is a legitimate form of art; but you must not bring a ghost into an ordinary novel to get over a difficulty in the plot. Now there is no doubt that a great deal of the modern objection to miracles is based on the suspicion that they are marvels of the wrong sort; that a story of a certain kind (Nature) is arbitrarily interfered with, to get the characters out of a difficulty, by events that do not really belong to that kind of story. Some people probably think of the Resurrection as a desperate last moment expedient to save the Hero from a situation which had got out of the Author’s control.
The reader may set his mind at rest. If I thought miracles were like that, I should not believe in them. If they have occurred, they have occurred because they are the very thing this universal story is about. They are not exceptions (however rarely they occur) not irrelevancies. They are precisely those chapters in this great story on which the plot turns. Death and Resurrection are what the story is about; and had we but eyes to see it, this has been hinted on every page, met us, in some disguise, at every turn, and even b
een muttered in conversations between such minor characters (if they are minor characters) as the vegetables. If you have hitherto disbelieved in miracles, it is worth pausing a moment to consider whether this is not chiefly because you thought you had discovered what the story was really about?—that atoms, and time and space and economics and politics were the main plot? And is it certain you were right? It is easy to make mistakes in such matters. A friend of mine wrote a play in which the main idea was that the hero had a pathological horror of trees and a mania for cutting them down. But naturally other things came in as well; there was some sort of love story mixed up with it. And the trees killed the man in the end. When my friend had written it, he sent it an older man to criticise. It came back with the comment, ‘Not bad. But I’d cut out those bits of padding about the trees’. To be sure, God might be expected to make a better story than my friend. But it is a very long story, with a complicated plot; and we are not, perhaps, very attentive readers.

ON PROBABILITY
Probability is founded on the presumption of a resemblance between those objects of which we have had experience and those of which we have had none; and therefore it is impossible that this presumption can arise from probability.
HUME, Treatise of Human Nature, I, iii, vi.
The argument up to date shows that miracles are possible and that there is nothing antecedently ridiculous in the stories which say that God has sometimes performed them. This does not mean, of course, that we are committed to believing all stories of miracles. Most stories about miraculous events are probably false: if it comes to that, most stories about natural events are false. Lies, exaggerations, misunderstandings and hearsay make up perhaps more than half of all that is said and written in the world. We must therefore find a criterion whereby to judge any particular story of the miraculous.
In one sense, of course, our criterion is plain. Those stories are to be accepted for which the historical evidence is sufficiently good. But then, as we saw at the outset, the answer to the question, ‘How much evidence should we require for this story?’ depends on our answer to the question, ‘How far is this story intrinsically probable?’ We must therefore find a criterion of probability.
The ordinary procedure of the modern historian, even if he admits the possibility of miracle, is to admit no particular instance of it until every possibility of ‘natural’ explanation has been tried and failed. That is, he will accept the most improbable ‘natural’ explanations rather than say that a miracle occurred. Collective hallucination, hypnotism of unconsenting spectators, widespread instantaneous conspiracy in lying by persons not otherwise known to be liars and not likely to gain by the lie—all these are known to be very improbable events: so improbable that, except for the special purpose of excluding a miracle, they are never suggested. But they are preferred to the admission of a miracle.
Such a procedure is, from the purely historical point of view, sheer midsummer madness unless we start by knowing that any Miracle whatever is more improbable than the most improbable natural event. Do we know this?
We must distinguish the different kinds of improbability. Since miracles are, by definition, rarer than other events, it is obviously improbable beforehand that one will occur at any given place and time. In that sense every miracle is improbable. But that sort of improbability does not make the story that a miracle has happened incredible; for in the same sense all events whatever were once improbable. It is immensely improbable beforehand that a pebble dropped from the stratosphere over London will hit any given spot or that any one particular person will win a large lottery. But the report that the pebble has landed outside such and such a shop or that Mr So-and-So has won the lottery is not at all incredible. When you consider the immense number of meetings and fertile unions between ancestors which were necessary in order that you should be born, you perceive that it was once immensely improbable that such a person as you should come to exist: but once you are here, the report of your existence is not in the least incredible. With probability of this kind—antecedent probability of chances—we are not here concerned. Our business is with historical probability.
Ever since Hume’s famous Essay it has been believed that historical statements about miracles are the most intrinsically improbable of all historical statements. According to Hume, probability rests on what may be called the majority vote of our past experiences. The more often a thing has been known to happen, the more probable it is that it should happen again; and the less often the less probable. Now the regularity of Nature’s course, says Hume, is supported by something better than the majority vote of past experiences: it is supported by their unanimous vote, or, as Hume says, by ‘firm and unalterable experience’. There is, in fact, ‘uniform experience’ against Miracle; otherwise, says Hume, it would not be a Miracle. A miracle is therefore the most improbable of all events. It is always more probable that the witnesses were lying or mistaken than that a miracle occurred.
Now of course we must agree with Hume that if there is absolutely ‘uniform experience’ against miracles, if in other words they have never happened, why then they never have. Unfortunately we know the experience against them to be uniform only if we know that all the reports of them are false. And we can know all the reports to be false only if we know already that miracles have never occurred. In fact, we are arguing in a circle.
There is also an objection to Hume which leads us deeper into our problem. The whole idea of Probability (as Hume understands it) depends on the principle of the Uniformity of Nature. Unless Nature always goes on in the same way, the fact that a thing had happened ten million times would not make it a whit more probable that it would happen again. And how do we know the Uniformity of Nature? A moment’s thought shows that we do not know it by experience. We observe many regularities in Nature. But of course all the observations that men have made or will make while the race lasts cover only a minute fraction of the events that actually go on. Our observations would therefore be of no use unless we felt sure that Nature when we are not watching her behaves in the same way as when we are: in other words, unless we believed in the Uniformity of Nature. Experience therefore cannot prove uniformity, because uniformity has to be assumed before experience proves anything. And mere length of experience does not help matters. It is no good saying, ‘Each fresh experience confirms our belief in uniformity and therefore we reasonably expect that it will always be confirmed’; for that argument works only on the assumption that the future will resemble the past—which is simply the assumption of Uniformity under a new name. Can we say that Uniformity is at any rate very probable? Unfortunately not. We have just seen that all probabilities depend on it. Unless Nature is uniform, nothing is either probable or improbable. And clearly the assumption which you have to make before there is any such thing as probability cannot itself be probable.
The odd thing is that no man knew this better than Hume. His Essay on Miracles is quite inconsistent with the more radical, and honourable, scepticism of his main work.
The question, ‘Do miracles occur?’ and the question, ‘Is the course of Nature absolutely uniform?’ are the same question asked in two different ways. Hume, by sleight of hand, treats them as two different questions. He first answers ‘Yes,’ to the question whether Nature is absolutely uniform: and then uses this ‘Yes’ as a ground for answering, ‘No,’ to the question, ‘Do miracles occur?’ The single real question which he set out to answer is never discussed at all. He gets the answer to one form of the question by assuming the answer to another form of the same question.
Probabilities of the kind that Hume is concerned with hold inside the framework of an assumed Uniformity of Nature. When the question of miracles is raised we are asking about the validity or perfection of the frame itself. No study of probabilities inside a given frame can ever tell us how probable it is that the frame itself can be violated. Granted a school timetable with French on Tuesday morning at ten o’clock, it is really prob
able that Jones, who always skimps his French preparation, will be in trouble next Tuesday, and that he was in trouble on any previous Tuesday. But what does this tell us about the probability of the timetable’s being altered? To find that out you must eavesdrop in the masters’ common-room. It is no use studying the timetable.
If we stick to Hume’s method, far from getting what he hoped (namely, the conclusion that all miracles are infinitely improbable) we get a complete deadlock. The only kind of probability he allows holds exclusively within the frame of uniformity. When uniformity is itself in question (and it is in question the moment we ask whether miracles occur) this kind of probability is suspended. And Hume knows no other. By his method, therefore, we cannot say that uniformity is either probable or improbable; and equally we cannot say that miracles are either probable or improbable. We have impounded both uniformity and miracles in a sort of limbo where probability and improbability can never come. This result is equally disastrous for the scientist and the theologian; but along Hume’s lines there is nothing whatever to be done about it.
Our only hope, then, will be to cast about for some quite different kind of Probability. Let us for the moment cease to ask what right we have to believe in the Uniformity of Nature and ask why in fact men do believe in it. I think the belief has three causes, two of which are irrational. In the first place we are creatures of habit. We expect new situations to resemble old ones. It is a tendency which we share with animals; one can see it working, often to very comic results, in our dogs and cats. In the second place, when we plan our actions, we have to leave out of account the theoretical possibility that Nature might not behave as usual tomorrow, because we can do nothing about it. It is not worth bothering about because no action can be taken to meet it. And what we habitually put out of our minds we soon forget. The picture of uniformity thus comes to dominate our minds without rival and we believe it. Both these causes are irrational and would be just as effective in building up a false belief as in building up a true one.
