Are Miracles Even Possible? David Hume

Here is Hume’s basic premise:

“And certainly, there’s no doubt about it, that in the past, and I think also in the present, for many evolutionists, evolution has functioned as something with elements which are, let us say, akin to being a secular religion … And it seems to me very clear that at some very basic level, evolution as a scientific theory makes a commitment to a kind of naturalism, namely, that at some level one is going to exclude miracles and these sorts of things come what may.”

If science is based on the law of causality then do miracles get in the way? Scientist and philosopher John Lennox explores this question, which was made popular by David Hume.

Some quotes:

Professor: “Miracles are impossible Sean, don’t you know science has disproven them, how could you believe in them [i.e., answered prayer, a man being raised from the dead, etc.].”

Student: “for clarity purposes I wish to get some definitions straight.  Would it be fair to say that science is generally defined as ‘the human activity of seeking natural explanations for what we observe in the world around us’?”

Professor: “Beautifully put, that is the basic definition of science in every text-book I read through my Doctoral journey.”

Student: “Wouldn’t you also say that a good definition of a miracle would be ‘and event in nature caused by something outside of nature’?”

Professor: “Yes, that would be an acceptable definition of ‘miracle.’”

Student: “But since you do not believe that anything outside of nature exists [materialism, dialectical materialism, empiricism, existentialism, naturalism, and humanism – whatever you wish to call it], you are ‘forced’ to conclude that miracles are impossible”

Christians claim that the birth, death, resurrection and ascension of Jesus Christ is the central chapter of world history. How do you measure such a one-off event? The writer, C.S. Lewis develops a reliable test: Does this “Grand Miracle” fit in with the rest of the Author’s other work – Nature itself?

The first Red Herring is this. Any day you may hear a man (and not necessarily a disbeliever in God) say of some alleged miracle, “No. Of course I don’t believe that. We know it is contrary to the laws of Nature. People could believe it in olden times because they didn’t know the laws of Nature. We know now that it is a scientific impossibility.”

By the “laws of Nature” such a man means, I think, the observed course of Nature. If he means anything more than that he is not the plain man I take him for but a philosophic Naturalist and will be dealt with in the next chapter. The man I have in view believes that mere experience (and specially those artificially contrived experiences which we call Experiments) can tell us what regularly happens in Nature. And he finks that what we have discovered excludes the possibility of Miracle. This is a confusion of mind.

Granted that miracles can occur, it is, of course, for experience to say whether one has done so on any given occasion. But mere experience, even if prolonged for a million years, cannot tell us whether the thing is possible. Experiment finds out what regularly happens in Nature: the norm or rule to which she works. Those who believe in miracles are not denying that there is such a norm or rule: they are only saying that it can be suspended. A miracle is by definition an exception.


The idea that the progress of science has somehow altered this question is closely bound up with the idea that people “in olden times” believed in them “because they didn’t know the laws of Nature.” Thus you will hear people say, “The early Christians believed that Christ was the son of a virgin, but we know that this is a scientific impossibility.” Such people seem to have an idea that belief in miracles arose at a period when men were so ignorant of the cause of nature that they did not perceive a miracle to be contrary to it. A moment’s thought shows this to be nonsense: and the story of the Virgin Birth is a particularly striking example. When St. Joseph discovered that his fiancee was going to have a baby, he not unnaturally decided to repudiate her. Why? Because he knew just as well as any modern gynaecologist that in the ordinary course of nature women do not have babies unless they have lain with men. No doubt the modern gynaecologist knows several things about birth and begetting which St. Joseph did not know. But those things do not concern the main point—that a virgin birth is contrary to the course of nature. And St. Joseph obviously knew that. In any sense in which it is true to say now, “The thing is scientifically impossible,” he would have said the same: the thing always was, and was always known to be, impossible unless the regular processes of nature were, in this particular case, being over-ruled or supplemented by something from beyond nature. When St. Joseph finally accepted the view that his fiancee’s pregnancy was due not to unchastity but to a miracle, he accepted the miracle as something contrary to the known order of nature. All records


It is therefore inaccurate to define a miracle as something that breaks the laws of Nature. It doesn’t. If I knock out my pipe I alter the position of a great many atoms: in the long run, and to an infinitesimal degree, of all the atoms there are. Nature digests or assimilates this event with perfect ease and harmonises it in a twinkling with all other events. It is one more bit of raw material for the laws to apply to, and they apply. I have simply thrown one event into the general cataract of events and it finds itself at home there and conforms to all other events. If God annihilates or creates or deflects a unit of matter He has created a new situation at that point. Immediately all Nature domiciles this new situation, makes it at home in her realm, adapts all other events to it. It finds itself conforming to all the laws. If God creates a miraculous spermatozoon in the body of a virgin, it does not proceed to break any laws. The laws at once take it over. Nature is ready. Pregnancy follows, according to all the normal laws, and nine months later a child is born. We see every day that physical nature is not in the least incommoded by the daily inrush of events from biological nature or from psychological nature. If events ever come from beyond Nature altogether, she will be no more incommoded by them. Be sure she will rush to the point where she is invaded, as the defensive forces rush to a cut in our finger, and there hasten to accommodate the newcomer. The moment it enters her realm it obeys all her laws. Miraculous wine will intoxicate, miraculous conception will lead to pregnancy, inspired books will suffer all the ordinary processes of textual corruption, miraculous bread will be digested. The divine art of miracle is not an art of suspending the pattern to which events conform but of feeding new events into that pattern.


A miracle is emphatically not an event without cause or without results. Its cause is the activity of God: its results follow according to Natural law. In the forward direction (i.e. during the time which follows its occurrence) it is interlocked with all Nature just like any other event. Its peculiarity is that it is not in that way interlocked backwards, interlocked with the previous history of Nature. And this is just what some people find intolerable. The reason they find it intolerable is that they start by taking Nature to be the whole of reality. And they are sure that all reality must be interrelated and consistent. I agree with them. But I think they have mistaken a partial system within reality, namely Nature, for the whole.

CS Lewis, Miracles (New York, NY: Touchstone Publishers, 1996), 62-63, 64-65, 80-81, 81-82.

STREAMING IN FROM SPACE, light reaches the human eye and deposits its information on the stippled surface of the retina. Directly thereafter I see the great lawn of Golden Gate Park; a young woman, nose ring twitching; a panting puppy; a rose bush; and beyond, a file of cars moving sedately toward the western sun. A three-dimensional world has been conveyed to a two-dimensional surface and then reconveyed to a three-dimension image.

This familiar miracle suggests, if anything does, the relevance of al­gorithms to the actual accomplishments of the mind; indeed, the trans­formation of dimensions is precisely the kind of activity that might be brought under the control of a formal program, a system of rules cued to the circumstances of vision as it takes place in a creature with two matched but somewhat asymmetrical eyes. David Marr, for example, provides (in Vision, 1982) an extraordinary account of the complex transformations undertaken in the mind’s cockpit in order to allow the eyes to see things stereoptically.


CHANCE ALONE,” THE NOBEL Prize-winning chemist Jacques Monod once wrote, “is at the source of every innovation, of all creation in Me biosphere. Pure chance, absolutely free but blind, is at the very root of  the stupendous edifice of creation.”

The sentiment expressed by these words has come to vex evolution­ary biologists. “This belief,” Richard Dawkins writes, “that Darwinian evolution is ‘random,’ is not merely false. It is the exact opposite of the truth.” But Monod is right and Dawkins wrong. Chance lies at the beat­ing heart of evolutionary theory, just as it lies at the beating heart of thermodynamics.

It is the second law of thermodynamics that holds dominion over the temporal organization of the universe, and what the law has to say we find verified by ordinary experience at every turn. Things fall apart. Energy, like talent, tends to squander itself. Liquids go from hot to luke­warm. And so does love. Disorder and despair overwhelm the human enterprise, filling our rooms and our lives with clutter. Decay is unyield­ing. Things go from bad to worse. And overall, they go only from bad to worse.

These grim certainties the second law abbreviates in the solemn and awful declaration that the entropy of the universe is tending toward a maximum. The final state in which entropy is maximized is simply more likely than any other state. The disintegration of my face reflects nothing more compelling than the odds. Sheer dumb luck.

But if things fall apart, they also come together. Life appears to offer at least a temporary rebuke to the second law of thermodynamics. Al­though biologists are unanimous in arguing that evolution has no goal, fixed from the first, it remains true nonetheless that living creatures have organized themselves into ever more elaborate and flexible structures. If their complexity is increasing, the entropy that surrounds them is de­creasing. Whatever the universe-as-a-whole may be doing-time fusing incomprehensibly with space, the great stars exploding indignantly—bi­ologically things have gone from bad to better, the show organized, or so it would seem, as a counterexample to the prevailing winds of fate.

How so? The question has historically been the pivot on which the assumption of religious belief has turned. How so? “God said: ‘Let the waters swarm with swarms of living creatures, and let fowl fly above the earth in the open firmament of heaven.”‘ That is how so. And who on the basis of experience would be inclined to disagree? The structures of life are complex, and complex structures get made in this, the purely human world, only by a process of deliberate design. An act of intelligence is required to bring even a thimble into being; why should the artifacts of life be different?

Darwin’s theory of evolution rejects this counsel of experience and intuition. Instead, the theory forges, at least in spirit, a perverse connection with the second law itself, arguing that precisely the same force that explains one turn of the cosmic wheel explains another: sheer dumb luck.

If the universe is for reasons of sheer dumb luck committed ulti­mately to a state of cosmic listlessness, it is also by sheer dumb luck that life first emerged on earth, the chemicals in the pre-biotic seas or soup illuminated and then invigorated by a fateful flash of lightning. It is again by sheer dumb luck that the first self-reproducing systems were created. The dense and ropy chains of RNA—they were created by sheer dumb luck, and sheer dumb luck drove the primitive chemicals of life to form a living cell. It is sheer dumb luck that alters the genetic message so that, from infernal nonsense, meaning for a moment emerges; and sheer dumb luck again that endows life with its opportunities, the space of pos­sibilities over which natural selection plays, sheer dumb luck creating the mammalian eye and the marsupial pouch, sheer dumb luck again en­dowing the elephant’s sensitive nose with nerves and the orchid’s trans­lucent petal with blush.

Amazing. Sheer dumb luck.

Philosophical Naturalism and the Modern Worldview

The second modern factor that has contributed to the widespread understanding that religious belief is private, practical, and relative, and need not be related to truth and reason is the widespread acceptance of philosophical naturalism as an expression of scientism. Philosophical naturalism is the idea that reality is exhausted by the spatio-temporal world of physical entities that we can investigate in the natural sciences. The natural causal Fabric of physical reality within the boundaries of space and time is all there is, was, or ever will be. The supernatural doesn’t exist except, perhaps, as a belief in people’s minds. On this view, religious beliefs are simply ways of looking at things in our search for meaning and purpose; they are not ideas that correspond to a mind-independent reality.

Philosophical naturalism is an expression of an epistemology (i.e., a theory of knowledge and justified or warranted belief) known as scientism. Scientism is the view that the natural sciencesare the very paradigm of truth and rationality. If something does not square with currently well-established beliefs, if it is not within the domain of entities appropriate for scientific investigation, or if it is not amenable to scientific methodology then it is not true or rational. Everything outside of science is a matter of mere belief and subjective opinion, of which rational assessment is impossible. Applied to the question of the historical origins of Christianity, scientism implies that since we live in the modern scientific world where the sun is the center of the solar system, the wireless is available for our use, and the atoms power has been harnessed, we can no longer believe in a biblical worldview with its miracles, demons, and supernatural realities.

Obviously, it is impossible in the brief space of an introduction to critique adequately scientism and naturalism. Still, a few cursory remarks need to be expressed.

(1) Scientism is simply false for three reasons. (a) It is self-refining, i.e., it falsifies itself. Why? Scientism is itself a statement of philosophy about knowledge and science; it is not a statement ofscience itself. Moreover, it is a statement of philosophy that amounts to the claim that no statements outside scientific ones, including scientism itself (because it is a statement of philosophy), can be true or supported by rational considerations. (b) Science itself rests on a number of assumptions: the existence of a theory-independent external world, the orderly nature of the external world, the existence of truth and the reliability of our senses and rational faculties to gather truth about the world in a trustworthy manner, the laws of logic and the truths of mathematics, the adequacy of language (including mathematical language) to describe the external world, the uniformity of nature, and soon. Now, each one of these assumptions is philosophical in nature. The task of stating, criticizing, and defending the assumptions of sci­ence rests in the field of philosophy. Scientism fails to leave room for these philosophical tasks and, thus, shows itself to be a foe and not a friend of science. (c) There are many things we know in religion, ethics, logic, mathematics, history, art, literature, and so on that are simply not matters of science. For exam­ple, we all know that two is an even number, that Napoleon lived, that torturing babies for fun is wrong, that if A is larger than B and B is larger than C, then A is larger than C, and so on. None of these items of knowledge are scientific in nature, and scientism is falsified by their reality.

(2) Philosophical naturalism is false as well. For one thing, philosophical naturalism rules out the existence of a number of things that do, in fact, exist. And while we cannot defend their existence here, suffice it to say that, currently, a number of intellectuals have offered convincing arguments for the reality of universals and other abstract objects such as numbers, the laws of logic, values, the soul and its various mental states (including the first person point of view), other minds, libertarian or full-blown freedom of the will, and so on. None of these items can be classified as mere physical objects totally within the causal fabric of the natural spatio-temporal universe. In fact, it is not an exaggeration to say that there is not a single issue of importance to human beings that is solely a matter of scientific investigation or that can be satisfactorily treated by philosophical naturalists.

(3) Philosophical naturalism fails to explain adequately the fact that there are a number of arguments and pieces of evidence that make belief in God more reasonable than disbelief. Some of this evidence actually comes from science: the fact that the universe had a beginning based on the Big Bang theory and the second law of thermodynamics, the existence of biological information in DNA that is closely analogous to intelligent language and that cannot arise from the accidental collisions of physical entities according to laws of nature, the reality of the mental and of free will according to a number of emerging psychological theories of the self, the delicate fine-tuning of the universe, and so on.”

Like it or not, a significant and growing number of scientists, historians of science, and philosophers of science see more scientific evidence now for a personal creator and designer than was available fifty years ago. In light of this evidence, it is false and naive to claim that modern science has made belief in the supernatural unreasonable. Such a view can be called ostrich naturalism—a position that requires its advocate to keep his or her head in the sand and not to acknowledge real advances in science. The plain truth is that science itself makes no statements about all of reality anyway, nor does science itself offer any support for philosophical naturalism. What does support philosophical naturalism are the ideological claims of naturalists themselves regarding what science ought to say if we assume philosophical naturalism to begin with.

In sum, it matters much that our religious beliefs are both true and reasonable. Moreover, there simply are no sufficient reasons for not believing in the supernatural, and there are in fact a number of good reasons (including but going beyond scientific ones) for believing in the supernatural. As we have said, space considerations do not permit us to defend this last claim here. But we will list some sources in the bibliography that adequately justify this claim. If you are an honest inquirer about the truth of religion, moral and intellectual integrity unite in placing a duty on you to read these works as a sincere seeker of the truth. It is well past time to rest content with the politically correct, unjustified assertions of scientism and philosophical naturalism. University libraries are filled with books that show the weaknesses of these views, and the fellows of the Jesus Seminar show virtually no indication that they have so much as interacted with the arguments they contain, much less have they refuted their claims.

Regarding Jesus of Nazareth, all of this means the following: Prior to inves­tigating the historical evidence about his life, deeds, sayings, and significance, there is no good reason to bring to the evidence a prior commitment to naturalism. As later chapters will show, such a commitment is Procrustean in that it often forces the evidence of history to fit an unjustified anti-supernatural bias. But when the evidence is evaluated on its own terms, and when such an evaluation is combined with the rigorous case for supernatural theism already available in the literature, then the claims of historic, orthodox Christianity can be reasonably judged to be true.

Here’s the first of Pennock’s arguments against methodological naturalism that I’ll consider:

  • allowing appeal to supernatural powers in science would make the scientist’s task too easy, because one would always be able to call upon the gods for quick theoretical assistance…. Indeed, all empirical investigation beyond the purely descriptive could cease, for scientists would have a ready-made answer for everything.

This argument strikes me as unfair. Consider a particular empirical phenomenon, like a chemical reaction, and imagine that scientists are trying to figure out why the reaction happened. Pennock would say that scientists who allow appeal to supernatural powers would have a ready-made answer: God did it. While it may be that that’s the only true explanation that can be given, a good scientist-including a good theistic scientist—would wonder whether there’s more to be said. Even if God were ultimately the cause of the reaction, one would still wonder if the proximate cause is a result of the chemicals that went into the reaction, and a good scientist—even a good theistic scientist—would investigate whether such a naturalistic account could be given.

To drive the point home, an analogy might be helpful. With the advent of quantum mechanics, scientists have become comfortable with indeterministic events. For example, when asked why a particular radioactive atom decayed at the exact time that it did, most physicists would say that there’s no reason it decayed at that particular time; it was just an indeterministic event!’ One could imagine an opponent of indeterminism giving an argument that’s analogous to Pennock’s:

  • allowing appeal to indeterministic processes in science would make the scientist’s task too easy, because one would always be able to call upon chance for quick theoretical assistance…. Indeed, all empirical investigation beyond the purely descriptive could cease, for scientists would have a ready-made answer for everything.

It is certainly possible that, for every event that happens, scientists could simply say “that’s the result of an indeterministic chancy process; there’s no further explanation for why the event happened that way.” But this would clearly be doing bad science: just because the option of appealing to indeterminism is there, it doesn’t follow that the option should always be used. The same holds for the option of appealing to supernatural powers.

As further evidence against Pennock, it’s worth pointing out that prominent scientists in the past have appealed to supernatural powers, without using them as a ready-made answer for everything. Newton is a good example of this—he is a devout theist, in addition to being a great scientist, and he thinks that God sometimes intervenes in the world. Pennock falsely implies that this is not the case:

  • God may have underwritten the active principles that govern the world described in [Newton’s] Principia and the Opticks, but He did not interrupt any of the equations or regularities therein. Johnson and other creationists who want to dismiss methodological naturalism would do well to consult Newton’s own rules of reasoning….

But in fact, Newton does not endorse methodological naturalism. In his Opticks, Newton claims that God sometimes intervenes in the world. Specifically, Newton thinks that, according to his laws of motion, the orbits of planets in our solar system are not stable over long periods of time, and his solution to this problem is to postulate that God occasionally adjusts the motions of the planets so as to ensure the continued stability of their orbits. Here’s a relevant passage from Newton. (It’s not completely obvious that Newton is saying that God will intervene but my interpretation is the standard one.)

  • God in the Beginning form’d Matter in solid, massy, hard, impenetrable, moveable Particles … it became him who created them to set them in order. And if he did so, it’s unphilosophical to seek for any other Origin of the World, or to pretend that it might arise out of a Chaos by the mere Laws of Nature; though being once form’d, it may continue by those Laws for many Ages. For while Comets move in very excentrick Orbs in all manner of Positions, blind Fate could never make all the Planets move one and the same way in Orbs concentrick, some inconsiderable Irregularities excepted, which may have risen from the mutual Actions of Comets and Planets upon one another, and which will be apt to increase, till this System wants a Reformation…. [God is] able by his Will to move the Bodies within his boundless uniform Sensorium, and thereby to form and reform the Parts of the Universe….

A scientist who writes this way does not sound like a scientist who is following methodological naturalism.

It’s worth noting that some contemporaries of Newton took issue with his view of God occasionally intervening in the universe. For example, Leibniz writes:

  • Sir Isaac Newton and his followers also have a very odd opinion concerning the work of God. According to them, God Almighty needs to wind up his watch from time to time; otherwise it would cease to move. He had not, it seems, sufficient foresight to make it a perpetual motion.”

Note, though, that Leibniz also thought that God intervened in the world:

  • I hold that when God works miracles, he does not do it in order to supply the wants of nature, but those of grace.

Later investigation revealed that in fact planetary orbits are more stable than Newton thought, so Newton’s appeal to supernatural powers wasn’t needed. But the key point is that Newton is willing to appeal to supernatural powers, without using the appeal to supernatural powers as a ready-made answer for everything.

Pennock says that “Without the binding assumption of uninterruptible natural law there would be absolute chaos in the scientific worldview.” Newton’s own approach to physics provides a good counterexample to this—Newton is a leading contributor to the scientific worldview, and yet he does not bind himself by the assumption of uninterruptible natural law.
