Miracles. C. S. Lewis

but immensely improbable, then only mathematically demonstrative evidence will convince us: and since history never provides that degree of evidence for any event, history can never convince us that a miracle occurred. If, on the other hand, miracles are not intrinsically improbable, then the existing evidence will be sufficient to convince us that quite a number of miracles have occurred. The result of our historical enquiries thus depends on the philosophical views which we have been holding before we even began to look at the evidence. This philosophical question must therefore come first.

      Here is an example of the sort of thing that happens if we omit the preliminary philosophical task, and rush on to the historical. In a popular commentary on the Bible you will find a discussion of the date at which the Fourth Gospel was written. The author says it must have been written after the execution of St Peter, because, in the Fourth Gospel, Christ is represented as predicting the execution of St Peter. ‘A book’, thinks the author, ‘cannot be written before events which it refers to’. Of course it cannot—unless real predictions ever occur. If they do, then this argument for the date is in ruins. And the author has not discussed at all whether real predictions are possible. He takes it for granted (perhaps unconsciously) that they are not. Perhaps he is right: but if he is, he has not discovered this principle by historical inquiry. He has brought his disbelief in predictions to his historical work, so to speak, ready made. Unless he had done so his historical conclusion about the date of the Fourth Gospel could not have been reached at all. His work is therefore quite useless to a person who wants to know whether predictions occur. The author gets to work only after he has already answered that question in the negative, and on grounds which he never communicates to us.

      This book is intended as a preliminary to historical inquiry. I am not a trained historian and I shall not examine the historical evidence for the Christian miracles. My effort is to put my readers in a position to do so. It is no use going to the texts until we have some idea about the possibility or probability of the miraculous. Those who assume that miracles cannot happen are merely wasting their time by looking into the texts: we know in advance what results they will find for they have begun by begging the question.

       THE NATURALIST AND THE SUPERNATURALIST

      ‘Gracious!’ exclaimed Mrs Snip, ‘and is there a place where people venture to live above ground?’ ‘I never heard of people living under ground,’ replied Tim, ‘before I came to Giant-Land’. ‘Came to Giant-Land!’ cried Mrs Snip, ‘why, isn’t everywhere Giant-Land?’

      ROLAND QUIZZ, Giant-Land, chap xxxii.

      I use the word Miracle to mean an interference with Nature by supernatural power.¹ Unless there exists, in addition to Nature, something else which we may call the supernatural, there can be no miracles. Some people believe that nothing exists except Nature; I call these people Naturalists. Others think that, besides Nature, there exists something else: I call them Supernaturalists. Our first question, therefore, is whether the Naturalists or the Supernaturalists are right. And here comes our first difficulty.

      Before the Naturalist and the Supernaturalist can begin to discuss their difference of opinion, they must surely have an agreed definition both of Nature and of Supernature. But unfortunately it is almost impossible to get such a definition. Just because the Naturalist thinks that nothing but Nature exists, the word Nature means to him merely ‘everything’ or ‘the whole show’ or ‘whatever there is’. And if that is what we mean by Nature, then of course nothing else exists. The real question between him and the Supernaturalist has evaded us. Some philosophers have defined Nature as ‘What we perceive with our five senses’. But this also is unsatisfactory; for we do not perceive our own emotions in that way, and yet they are presumably ‘natural’ events. In order to avoid this deadlock and to discover what the Naturalist and the Supernaturalist are really differing about, we must approach our problem in a more roundabout way.

      I begin by considering the following sentences (1) Are those his natural teeth or a set? (2) The dog in his natural state is covered with fleas. (3) I love to get away from tilled lands and metalled roads and be alone with Nature. (4) Do be natural. Why are you so affected? (5) It may have been wrong to kiss her but it was very natural.

      A common thread of meaning in all these usages can easily be discovered. The natural teeth are those which grow in the mouth; we do not have to design them, make them, or fit them. The dog’s natural state is the one he will be in if no one takes soap and water and prevents it. The countryside where Nature reigns supreme is the one where soil, weather and vegetation produce their results unhelped and unimpeded by man. Natural behaviour is the behaviour which people would exhibit if they were not at pains to alter it. The natural kiss is the kiss which will be given if moral or prudential considerations do not intervene. In all the examples Nature means what happens ‘of itself’ or ‘of its own accord’: what you do not need to labour for; what you will get if you take no measures to stop it. The Greek word for Nature (Physis) is connected with the Greek verb for ‘to grow’; Latin Natura, with the verb ‘to be born’. The Natural is what springs up, or comes forth, or arrives, or goes on, of its own accord: the given, what is there already: the spontaneous, the unintended, the unsolicited.

      What the Naturalist believes is that the ultimate Fact, the thing you can’t go behind, is a vast process in space and time which is going on of its own accord. Inside that total system every particular event (such as your sitting reading this book) happens because some other event has happened; in the long run, because the Total Event is happening. Each particular thing (such as this page) is what it is because other things are what they are; and so, eventually, because the whole system is what it is. All the things and events are so completely interlocked that no one of them can claim the slightest independence from ‘the whole show’. None of them exists ‘on its own’ or ‘goes on of its own accord’ except in the sense that is exhibits, at some particular place and time, that general ‘existence on its own’ or ‘behaviour of its own accord’ which belongs to ‘Nature’ (the great total interlocked event) as a whole. Thus no thoroughgoing Naturalist believes in free will: for free will would mean that human beings have the power of independent action, the power of doing something more or other than what was involved by the total series of events. And any such separate power of originating events is what the Naturalist denies. Spontaneity, originality, action ‘on its own’, is a privilege reserved for ‘the whole show’, which he calls Nature.

      The Supernaturalist agrees with the Naturalist that there must be something which exists in its own right; some basic Fact whose existence it would be nonsensical to try to explain because this Fact is itself the ground or starting-point of all explanations. But he does not identify this Fact with ‘the whole show’. He thinks that things fall into two classes. In the first class we find either things or (more probably) One Thing which is basic and original, which exists on its own. In the second we find things which are merely derivative from that One Thing. The one basic Thing has caused all the other things to be. It exists on its own; they exist because it exists. They will cease to exist if it ever ceases to maintain them in existence; they will be altered if it ever alters them.

      The difference between the two views might be expressed by saying that Naturalism gives us a democratic, Supernaturalism a monarchical, picture of reality. The Naturalist thinks that the privilege of ‘being on its own’ resides in the total mass of things, just as in a democracy sovereignty resides in the whole mass of the people. The Supernaturalist thinks that this privilege belongs to some things or (more probably) One Thing and not to others—just as, in a real monarchy, the king has sovereignty and the people have not. And just as, in a democracy, all citizens are equal, so for the Naturalist one thing or event is as good as another, in the sense that they are all equally dependent on the total system of things. Indeed each of them is only the way in which the character of that total system exhibits itself at a particular point in space and time. The Supernaturalist, on the other hand, believes that the one original or self-existent thing is on a different level from, and more important than, all other things.
