Chapter 10 Summary: “Horrid Red Things”

Whereas the last chapter dealt with the objectors who feel that the idea of miracles makes a mockery of nature, this chapter begins with those who feel that miracles make a mockery of the supernatural—that there is an elevated dignity to the divine which is lost by portraying supernatural reality as breaking in and meddling with mere earthly things. Such people are likely to find traditional Christianity’s insistence on practical, earthy miracles like the Virgin Birth of the Son of God to be distasteful. To say that Jesus “came down from heaven” or to picture God as a bearded man on a throne strikes such a critic as absurd and primitive, and Lewis acknowledges that some Christians take such symbolic language to absurd degrees. Nevertheless, he argues, this does not discount the actual core truth of the miracle: Even once one realizes (as Christianity has always taught) that heaven is not a place “up there” from which someone physically descended, such a realization does nothing to change the Christian insistence that a miracle has taken place: The Son of God has stepped out of eternity and into history to be with us. Nor does recognizing the anthropomorphic language about God as symbolic do anything to negate the underlying doctrine: that the all-wise God reigns sovereignly over all that is. Lewis defends the dramatic picture of the Christian story, officially expressed in doctrinal language that grasps toward the eternal and ineffable, against the merely popular and trivialized conceptions that are too often passed around as the stereotyped version of what Christianity is all about. To reject Christianity, Lewis believes, one must not simply write off the trivialized picture of miracles that are made to sound like magic tricks, but must wrestle with the philosophical rigor and numinous majesty of its classical expression, wherein the miracles are representations of the world-shaking events of the incarnation of Christ. One must not judge merely on one’s own surface perceptions of Christian doctrine, but must have the intellectual honesty to grapple with it as it actually is.

Chapter 11 Summary: “Christianity and ‘Religion’”

Having addressed some of the instinctive disaffections which some in his audience will have against Christianity, Lewis now begins to assess the religious sentiments of the modern world in greater detail. In his day, many held a generalized sensibility of the supernatural as a broad, vague, all-encompassing force, rather than as a divine person. Religious people with such conceptions are comfortable to speak about God in broad, nebulous terms, as that which is good, true, and beautiful, but shy away from describing God with the particularities of an active and personal Agent. Lewis calls this religious sensibility pantheism, and suggests that rather than the aura of enlightened cultural respectability in which it has wrapped itself, it is in fact the most “primitive” form of religion one could imagine (thus Lewis turns such people’s criticisms of Christianity—as being primitive and superstitious—back on themselves).


Lewis describes the distinction between Christianity and what he calls pantheism as analogous to the distinction between quantum and Newtonian physics. The “pantheistic” view of the supernatural—as a universal spiritual presence which is there to comfort and bless us—feels intuitive and familiar to most people, like the Newtonian understanding of physical laws, in which discrete particles go through a harmonious dance of ordered motion. By contrast, the true Christian understanding of the supernatural is like quantum physics, which shocks us with a view of how things actually are: bizarre and unpredictable in ways that most people can’t quite wrap their minds around. In the same way, says Lewis, Christianity shocks us with its insistence on something more than a vague and comfortable spirituality: a universe in which a radically personal God chose to become directly involved in our world in the most undignified way imaginable. In that sense, while Christianity may not be comfortably intuitive, it has the ring of truth about it, the flavor of the counter-intuitive way that things really are.


Lewis grounds this view in the classical philosophical distinction between necessary and contingent beings (although Lewis does not use the full philosophical terminology), arguing that the particularity of contingent things in our universe necessitates the existence of a ground for their particularity. In short, there must be some uncreated thing that started it all, and it must itself be a particular thing, not merely a generalized something. “God is basic Fact or Actuality, the source of all other facthood. At all costs therefore He must not be thought of as a featureless generality. If He exists at all, He is the most concrete thing there is, the most individual […]” (145).

Chapter 12 Summary: “The Propriety of Miracles”

Here Lewis returns to address the concerns of those who think that performing miracles is unworthy of God, that it makes God a trickster or magician. Lewis compares this view to a misunderstanding of how a great artist might operate when painting. Such an artist will not break any of the “laws” which dictate the true internal purpose of the masterpiece they are creating, but they will break any number of popular conceptions or rules of thumb people may hold about artistic conventions. This is not an inconsistency, but one of the features that makes the artwork truly great; in the same way, God’s miracles are not inconsistencies or violations of some rule that ought to be kept in force, but are themselves part of the flair and vision that brings the whole work together. Lewis then transitions from the analogy of an artist to that of an author. Depending on the story one is writing, an author’s inclusion of seemingly magical events might be bad writing if one is making a realistic novel, but if one is writing a story about the magical events themselves, then the author has every right to include them, and in fact would be inconsistent if they did not.

Chapter 13 Summary: “On Probability”

Lewis observes that historians will tend to discount miraculous stories in favor of a naturalistic explanation for a surprising event, regardless of how wildly improbable the naturalistic explanation might be. This perspective, quite obviously, assumes that miracles must be far unlikelier than even the remotest naturalistic possibility, but Lewis challenges whether that assumption is true. He argues against the philosophy of David Hume, whose work in the 18th century set in motion much of the later Western skepticism regarding miracles. Lewis takes issue with Hume’s approach, arguing that someone in Hume’s position needs to have already decided that miracles are necessarily the most improbable events in order to reach Hume’s conclusions. In Lewis’s view, Hume confuses the observed uniformity of nature with the question of whether it is probable or improbable as to whether the frame within which that uniformity takes place can admit any interpositions. Since nature is uniform, says Hume, miracles cannot happen, but this position mistakes miracles as something that merely happen within the “frame” rather than something from beyond it, and so Hume’s assumed probabilities do not hold: “No study of probabilities within a given frame can ever tell us how probable it is that the frame itself can be violated” (164).


Lewis goes on to suggest that even our conviction that nature is uniform in its operations (or ought to be so) is an act of faith, one which nature itself—if naturalism is true—gives no necessary reason for believing. As a nonrational system without design, a naturalistic universe would have just as much reason to be continuously random as it would to be uniform. Lewis notes that it was only the Christian-inspired belief in a divine Legislator (God) on the part of early scientists that inspired a conviction that there must be uniform laws governing nature. And once this admission of God into the equation is grasped, then one must be open to miracles: “Theology says to you in effect, ‘Admit God and with Him the risk of a few miracles, and I in return will ratify your faith in uniformity as regards the overwhelming majority of events” (169).

Chapters 10-13 Analysis

This set of chapters brings Lewis’s attention ever more to bear on the question of Christianity. Now the issue is not merely the philosophical possibility of miracles (though that is still in view), but whether the presentation of miracles within a specifically Christian context makes any sense.


It is worth pointing out one of the major issues that Lewis skips over without addressing in detail: the question of miracles in other religious systems. Christians are not the only people in the world who hold that miracles happen—many of the Old Testament miracles that Lewis views as foreshadowing or preparing the way for Jesus are understood quite differently in a Jewish context, for example—so a relevant question, perhaps for something beyond a “Preliminary Study,” as the book’s subtitle has it, would be whether miracles in other religious traditions can be dealt with under the same rubric Lewis uses for Christianity. Lewis does maintain, however, that miracles occupy a uniquely central position in Christianity, since its entire founding premise—the divine identity and salvific work of Jesus Christ—is the story of a miracle.


Lewis continues using the literary device of vivid analogies, and these chapters show the range of his usage, from the intellectual to the popular. He draws these analogies from a wide range of fields, from quantum physics to art and literature. Yet in each case, Lewis aims his rhetoric toward a general audience, so that even a reader with no real experience in quantum physics would still be able to follow the point of the analogy. Similarly, in addressing David Hume’s use of probabilistic arguments, Lewis takes the time to explain Hume’s philosophical jargon and expresses his own argument in plain language as much as possible, with the aim that readers who aren’t steeped in the language and customs of academic philosophy will be able to follow the flow of Lewis’s argument, even if they might struggle to understand Hume’s.


The thematic emphases in this section of the book now also begin to shift, starting to move away from polemical arguments (against naturalism) to apologetic ones (in defense of Christianity). As such, the theme of Cultural Bias as the Root of the Modern Rejection of Miracles recedes into the background, though it is still evident in these chapters, perhaps most clearly in Lewis’s treatment of David Hume in Chapter 13. Hume stands at the fountainhead of much of the skepticism that created the cultural bias against miracles, and so Lewis’s interaction with his philosophical system (undertaken at this stage in the book because Hume, like Lewis, was primarily concerned with miracles in a Christian context) aims to combat that bias. 


Lewis’s contention that Miracles Do Not Violate The Laws of Nature is also briefly addressed in Chapter 12, as Lewis uses the work of artistic production as an analogy for the relationship between God and the natural world. This analogy is another example of Lewis’s appeal to logos—or the argument from reason. He argues that just as the artist may break any number of cultural conventions in service of the internal law—the intrinsic aesthetic harmony—of their own work, so God can suspend the laws of nature in service of a larger, divine order. Throughout the book, analogies like this one aim to express complex philosophical concepts by comparing them to more familiar ideas. 


The third major theme of the book, The Incarnation of Jesus Christ as Central to All Miracles, begins to receive its first major treatment in this section, though not as robustly as it will feature in the book’s final chapters. As Lewis begins to touch on biblical miracles in Chapter 10, the focus of the book zeroes in on those particular miracles as its central concern: the Virgin Birth, the resurrection, the ascension, and so on—the miraculous events of the life and person of Jesus Christ. This focus continues throughout the section, developing in Chapter 11 with Lewis’s argument for the particularity and person-focused nature of miracles in Christianity, suggesting that it all comes down to the personal identity of a God who really is there, and whose deeds bring meaning to everything else in the narrative.
