Original Sin, Paradise and Irish Music

In a comment to my recent post concerning Chesterton and Original Sin, M asked the pertinent question: If this is our true home but we don't know how to live here, how do we learn?

The short answer is we can't, at least on our own. That's the problem with the Fall - we fell in our entire nature right down to our core, so there is no place we can fall back on from which to pull ourselves up. Any attempt we make is doomed to fail because the attempt can only come from fallen nature, and so is already affected by the problem it is trying to cure. That's why our attempts to find a way to live always have a ring of artificiality to them. They must, because we are trying to construct a way to live from degraded blueprints and with degraded carpenters.

The only answer is for someone to save us - which, of course, God has accomplished in the Incarnation. Christ shows us what it really means to live naturally, in our home, and gives us the grace to do it, if we will but accept it. Just how far we have fallen is indicated by the shock with which we apprehend the crucifix:

Christ is the perfectly natural man, but the way He lives is not something that comes naturally to us (anymore).  And it never quite will, as long as redemption is not complete. The best we can do is imitate him, ask for His grace, and hope we can through Him learn to live again in a truly natural manner. In the meantime, we can console ourselves with the knowledge that the strangeness we feel, the feeling of never quite fitting in or knowing quite what to do, is a consequence of the Fall, and will be with us to some degree for the rest of this life - but it is not the end of the story, and we can look forward to truly being home when history is finished.

And we can even in this life get a taste of what paradise - another word for living in our true home - is like. We know that in paradise we will live in the presence of God and no longer feel the longing that we do in this life, that something isn't there that should be but we can't quite say what. God will fill us and we will rest satisfied in Him. It's difficult for us to imagine how this would be possible, how we could rest in God without becoming bored (another indication of our fallen nature). For me, I imagine paradise as a "dynamic restfulness",  active yet not going anywhere or feeling the need to go anywhere. One way I get an idea for this is playing Irish music; when you get the rhythm right in a reel, it feels effortless and as though you could ride the rhythm all day without trying but without getting bored. It's that "dynamic restfulness" I strive for in my playing and when I approach it, I feel I am getting a little taste of heaven. This is the Irish reel Lucky In Love:

On Living Together

I am old-fashioned enough to still be surprised at the matter-of-fact way couples allow it to be known that they are living together without benefit of clergy. It now seems to be the conventional wisdom that couples live together for months or even years before getting married, if they ever do. A young man at work has been living with his girlfriend for four years. He has even gone on cruises with his parents and her; apparently the parents see nothing amiss in this relationship. This is all related matter of factly over the lunch table.

The idea seems to be that you should get to know each other in a living-together arrangement before getting married. That way, the thinking goes, there won't be surprises when (if) you eventually do get married. Supposedly this will put the marriage on a firmer basis. The statistics say otherwise.

So does common sense and, frankly, simple decency. I thank God that I had the sense not to go down this path when I was 23 and foolish in many ways - but not that way. Instead I married the woman I loved - without ever having lived with her - and have stayed married for 29 years.

Jan. 3, 1987

I instinctively sensed at the time that to ask her to live with me would be disrespectful. It was to ask her to upset the basic arrangements of her life - where she lived and how, the independence of her own apartment - and restructure her life according to mine, presumably for some extended period of time. It meant a raft of simple things like letting everyone know the new telephone number at which you can be reached, and changing your mailing address. There was an "overhead" investment that would act to discourage her from ending the arrangements should she so desire; not to mention the embarrassment of admitting failure after, say, two years of living with someone.

Yet with no commitment from me that this fundamental restructuring would lead anywhere. This is to put the woman you supposedly love at a disadvantage. It is to take her out for a test drive like she is a used car.  To really love someone is to wish the best for her, and to presume to take several of the best years of someone's life, years when she is young and single and looking for the right man, as exclusively your own yet with the explicit proviso that you may discard her at any time - how can a man do this to the woman he loves?

It doesn't matter if she "agrees" with it. Simply because someone shows no respect for himself or herself does not give one license to disrespect him or her as well. At bottom, such a relationship is one that mimics the appearance of genuine self-giving marriage, but is at heart really a relationship of two people using each other rather than giving themselves to each other. That is the whole point of avoiding marriage, isn't it? I'll see how you work for me for a time and decide then if it's been worth it.

And then, if such a couple finally does get married, the character of their relationship has already been formed. They have been living together for all appearances as man and wife. Now that they really are man and wife, will their relationship suddenly change from the one of mutual use it has been, to the mutual self-giving of genuine marriage? I doubt it very much. In fact, I suspect they would have difficulty even conceiving the self-giving involved in genuine marriage. Instead, while the formality of marriage would add more "overhead" to the relationship in the sense of making it more difficult to break up, it wouldn't change the fundamental possibility of that breakup, which has been foundational in their relationship since the beginning.

Consider also that everyone shows the best sides of themselves when getting to know someone. From the first instance of meeting, we try to put our best face forward and hide our less attractive aspects. As we get to know someone, we gradually reveal more of ourselves, including those less attractive elements, doing so to the degree that we believe we can trust the one to whom we are revealing it.  Now the whole point of living with someone without marriage is to hold open the option of leaving them at any time; in other words, it puts a lack of trust at the center of the relationship. In such circumstances, people will hide those unattractive elements. And I'm sure they can do so for years at a time.

In other words, you can live with someone for a long time without truly knowing her should she choose not to reveal herself. The point of the living together arrangements, however, is a sort of truth in advertising: I insist on knowing exactly what I'm buying before I do so in marriage. Imagine a man's perplexity after five years of living with someone, that after a year of marriage he's discovering sides of his wife's personality he never dreamed were there. She thinks, of course, that now that they are married she has the level of trust necessary to finally reveal herself completely. For his part, he may feel he's been taken advantage of: I was supposed to find out all this beforehand, and she held it back from me, so she's gone back on our arrangement.

Of course, demanding that someone reveal her deepest self to you in an arrangement constructed so that you can examine that self and decide if you like it or not, and then decide whether or not to discard her, is deeply disrespectful. Again, it doesn't matter if both parties are doing it to each other. Mutual disrespect is a very poor form of equality and certainly no basis for marriage.

The fact is that genuine marriage involves tremendous risk; that is one of the things that makes it so exciting. Real marriage is an adventure that involves much deeper risk than rock climbing or skydiving. You don't really know your marriage partner until you have been married for a time and they have fully revealed themselves. And both of you know this going in; to some degree, you are marrying a stranger.

What sense, then, does the marriage vow make? How can you promise yourself to a person you don't really know, and won't really know perhaps for years? The French philosopher Gabriel Marcel addressed this question in his book Creative Fidelity. The title neatly summarizes his answer: In marriage, the partners create the conditions under which they remain faithful. What they are vowing themselves to is not just a person, but a mutual journey of discovery and self-creation, where the partners discover each other and themselves, changing and growing in the process. I am not the man I was when I married at age 23; and I am not the man I would have been had I not married or even married someone other than Tricia. She has been a dynamic element of my self-creation over the last 29 years, and I of hers.

That sounds very abstract, but it is extremely concrete in practice. It means being able to confront and discuss aspects of your partner's personality that you find difficult and, perhaps, even impossible to live with over the long term. Will they do what is necessary to develop that aspect of themselves for the sake of the marriage? And of course it runs the other way as well: I discover things about myself through her that I had not noticed, but are unpleasant for her. Am I willing to work on those things for the sake of her happiness, or will I demand that she take me as I am? Not all things can be changed. The ongoing negotiation and development, in the context of love, is the substance of marriage.

This dynamic process of growth is stunted if the partners have gone into marriage after a trial period of living together; for they have already sent each other the message that they reserve the right to bail out if they find they don't like what they see, instead of sending the message that they are committed to the process of change and growth no matter what.

The result is not a more secure marriage, but a marriage in which the trust necessary for the deepest communication will be difficult to find.

Chesterton and Original Sin

From the introduction to The Defendant in the collection of essays In Defense of Sanity:

This is the great fall, the fall by which the fish forgets the sea, the ox forgets the meadow, the clerk forgets the city, every man forgets his environment and, in the fullest and most literal sense, forgets himself. This is the real fall of Adam, and it is a spiritual fall.

The rest of the animal kingdom has an advantage on us: They are what they are and can be nothing else. A bear cannot fail to be bearlike, or a worm wormlike. But man can fail to be human. Chesterton's wonderful description of Original Sin, imagining what it might be like should an animal suffer it, illuminates what it means for us. Imagine a fish that forgets the sea; meaning, I think, a fish who forgets how to live in the sea as a fish. Such a fish is never home, for the only home it could possibly know, the sea, is foreign to it. It must live its entire existence as a stranger in its own home.

Even better is the ox who forgets the meadow. Unlike the fish, for whom the entire sea is all home to it, or should be, the meadow is peculiarly the home for an ox. An ox in the city or on a mountain is not home. But the ox who forgets the meadow is still not home in the city or on the mountain; like the unfallen ox that finds itself in the city, it would search for home. But while the unfallen ox would recognize the meadow as home should it find it, the fallen ox may find the meadow but would, tragically, not recognize it as home... it would wander right through home and continue to pine for the home it already found.

The great fall for man means that he has lost the knowledge of how to live as man in the world; he feels that he is not at home, or that he should be home but somehow isn't. So what does he do? What can he do? A man at home lives naturally; he doesn't have to figure out how to live. Since we are not at home - or at least we have forgotten how to live at home - we must construct ways of living. And these ways are at some level false simply because they are constructed - they can never replace the natural way of living of unfallen man.

Rousseau noticed this artificiality but rejected Original Sin; for him, the social constructions of man are the fall rather than a consequence of the fall. This has the convenient consequence that the fall lies outside us rather than in us, and in dealing with it we don't have to change.

But the truth is that there is no state of nature that is our true home, and in which we would be at peace could we find it. We are already in our true home. We just don't know how to live here.

Matthew 11:28-30

Come unto me all ye that labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly of heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.

What is it to be "heavy laden"? For me, it has been the effort to make my life meaningful by filling it up. You get one shot at life, I thought, and I didn't want to waste it. So I've got to be something and do things, and I've got to start right now, because life is passing by even as I speak. This was how I thought as a young man.

But be what and do what? That's not so easy a question to answer. For there is the problem of opportunity cost. To do something or to be something is implicitly to choose not to do or be all the other things you could have done or been. To become an engineer is not to become an English teacher, an historian, or a philosopher. Suppose you choose the wrong thing? You will have invested long time and effort to become something you should never have been. And there is no "do-over." You can't get those years back that you invested in becoming something you were not.

I always envied the nerds who knew who and what they were: engineers. No anxious struggle about life's direction for them. I, on the other hand, could be interested in just about anything but not overwhelming passionate about anything. So I would flit from thing to thing, hoping to land on one that I would somehow know was "me", like finding the girl you "just knew" was the one for you.

In his Either:Or, Kierkegaard discusses something he calls the "rotation method": This is a way someone bored with life keeps himself from going crazy. What he does is pursue an interest for a while until it becomes fatigued and he is bored with it. He then moves onto another interest, going from one to another until he eventually, after enough time, comes back to the first which has become interesting again through neglect. This was essentially what I did. My best friend used to ask me what "kick" I was currently on.

There is an alternative. And that is, instead of trying to fill up your life with either things you are becoming or things you are doing, to recognize the futility of that approach, and instead empty your life. But isn't that just giving up on life itself? Yes, it is and would be, and is why the great philosophers like Aristotle did not recommend it. But the fact of Christ changes everything.

For by emptying yourself and taking on the burden offered by Christ, you open yourself to the possibility that Christ Himself will fill you, and satisfy you in a way not possible for anything on Earth. As Kierkegaard would say, it is the difference between filling yourself with the eternal versus the merely temporary.

That sounds all well and good, but how do I know such satisfaction is an actual reality rather than, say, merely a pious hope? For if it is merely a pious hope, then the apparent death that would happen if I empty myself is an actual death. The rotation method may be unsatisfying and ultimately lead to despair, but at least it is something, and I get at least the satisfaction that I am trying.

This is where the matter of faith comes in. Faith in this context does not mean a blind belief in something you know to be false or have no reason to believe is true. It means to act take a chance and act on trust. Is the Gospel true? Did Jesus Christ really rise from the dead and show that a life of self-emptying is really a life of true fulfillment rather than a living death? I cannot prove that in any absolute sense. But then I don't think that is necessary. At least it wasn't for me.

It was enough for me to establish that the Gospel was at least plausible. Furthermore, I was and am firmly convinced that something highly unusual happened in Palestine in the first century. For the events that launched the Christian religion form a hinge point in history, one that turned the world from an eternal cycle of civilizational births and deaths, with one epoch not so different from any prior one, to a world launched in history, one condemned to development and change, and charging through time to some denouement to happen when no one knows. (See Chesterton's The Everlasting Man for the classic development of this theme.)

The conviction that something transcendent happened at the origin of the Christian religion, and my own recognition of the futility of trying to make life significant by filling it up, was enough to allow me to make the act of faith in renouncing the life I had been following and instead attempt to empty it and follow Christ. Yes, there was a bit of Pascal's Wager going on here.

What does it mean to embrace a self-emptying life in the name of Christ? It means to sacrifice all things you might have become or done for the sake of following Christ, and that means living for others rather than yourself. For me, it meant that instead of pursuing various hobbies obsessively I would spend that time coaching youth soccer or playing games with my children. It meant accepting a professional career that I might not have been passionate about, but was competent enough at to be successful enough to support a family. And it is to accept that as the years go on, working at a job that is just a job, and getting older and slower, missing the experiences I might have had, that in fact I was not slowly dying but rather accumulating treasure in Heaven, which is Christ Himself.

There are consolations. The vanity of earthly pursuits becomes more obvious as one grows older. And  we find that there are earthly rewards as well: Matthew 6:33. But these rewards also constitute a temptation, for they renew the possibility of life as self-fulfillment: I have filled my life with family rather than experiences or personal development. If we are following Christ, we devote ourselves to our family for His sake, not our own. If we give in to the temptation to the latter, then we are open to grasping after our family (e.g. helicopter parenting, or forcing our children to take their freedom when they are older rather than giving it to them as free equals.)

And it's not like flipping a switch. More like a slow process where one gradually weans oneself from the temptation to grasp at life rather than renounce it for Christ. And I am constantly tempted to grasp, especially in retrospect. The last few years I have taken up long distance running as a way to avoid getting old faster than necessary. Running a weekly 5k fun run here in town, I find myself envying the younger men (in their 30's and 40's) who did not wait until they were 50 to take the sport seriously. I wonder what I could have done had I taken running more seriously back then. But at that time I was changing diapers, or coaching youth soccer teams, or going to little league games, or playing board games with my daughter. I imagine an alternative history in which I have filled my life with such things and am happy, a history that I know is a lie, and thank God that he gave me the grace to see the futility of that life before I had misspent it.

Brute Facts

A typical argument for atheism goes like this (in simplified form): Both the atheist and the theist start with a "brute fact", i.e. something that "just is." The theist argues from the existence of the universe ("What caused the universe?") to God (something that "just is.") The atheist responds that if we must accept something that "just is", why not say it is the universe rather than hypothesizing something beyond it like God? That merely, ala Ockham, multiplies hypothetical entities unnecessarily. The universe "just is" and there is no need for God.

It isn't true that the cosmological arguments for God put forward by the great classical philosophers like Aquinas considered God as something that "just is." Indeed, the whole point of the arguments are to establish the existence of something that is much more than something that "just is."

But that is beside the point of the present post, which is to explore the notion of brute facts or things that "just are." My conclusion is that brute facts are intellectually dangerous things, and destroy far more than their deployers suppose. They want to aim the cannon of brute facts at God, but the consequent explosion blows up not just God but our understanding of the universe itself.

Consider what it is to be a "brute" fact. Something that is "brute" is something unintelligible; that is why animals are called "brutes", because they do not possess reason. A "brute" fact is a fact that is unintelligible beyond the bare fact that it is. Clearly, if a fact is brute, there is no point in asking anything more about it, since there is nothing more about it that we can know.

Here is the rub. How do we know a brute fact for what it is when we encounter it? What distinguishes brute facts from intelligible facts? Intelligible facts are facts for which we can find an explanation, you say. But there is nothing to say that brute facts can't appear to have an explanation when they really don't.  That, in fact, is the whole point of the atheist's brute fact argument against the theist: His argument is not that God doesn't really explain the universe should He exist, but that the universe in fact does not stand in need of an explanation in the first place because it is brute.

Newton's theory of gravitation appears to explain why the moon orbits the earth and planets orbit the sun. Perhaps, however, those celestial movements are really only brute facts; then Newton's theory only appears to explain the solar system. You scoff because it is clear that Newton's theory does in fact explain the solar system; it is ridiculous to suppose that it is just by chance that all the planets and their moons happen to orbit in accordance with Newton's theory.

And I would agree, but only because I do not accept the notion of brute facts. For smuggled in your reply is the assumption that you have some idea of the nature of brute facts: Brute facts wouldn't appear to happen in such a way that they conform with some intelligible law. In doing so, however, you have implicitly denied the notion of brute facts, for brute facts are facts about which you can say nothing at all further than the fact that they are (or might be). We can't say what they are like or what they are unlike or how they might appear or how it is impossible for them to appear. Any supposition along any of these lines is to contradict the brute nature of the supposed brute fact: It is to concede that the fact is in some measure intelligible; if we can say how brute facts cannot appear to us, then we have conceded that brute facts are in some measure knowable beyond the fact that they are, and therefore are not brute.

One of the virtues of David Hume was that he took the notion of brute facts seriously. And he saw that if we allow the notion of brute facts through the door, then we have destroyed the intelligibility of causality altogether and not just for the universe or God. For we never see causality itself, says Hume, only one event following another. And if we don't presuppose that the universe is intelligible, that is, if we take it that brute facts might be lurking around every corner, then the fact that one type of event tends to follow another might just be one of those brute facts waiting to temp us into false conclusions about causality. We might mistake our becoming accustomed to breaking glass following the flight of a brick for insight into a casual relationship between flying bricks and broken glass, when in fact their relationship might just be a brute fact.

Kant, of course, noticed that Hume's position not only undermined the traditional arguments for God but also any possibility of an actual understanding of the universe, including that of modern science. Kant furthered the Humean project by offering an explanation as to why we tend to (falsely) infer causality into the universe. Kant reflects on the fact of experience, and claims that the only way we can have connected experience is for our cognitive faculties to organize it out of the blooming, buzzing confusion around us. In other words, our minds are constructed so as to read into nature notions like causality and substance so that we can deal with it. A very clever advance on Hume, which saved science from Hume's skepticism, but at the price of recasting the subject of science from being nature itself to merely how nature appears to us given our cognitive apparatus.

The point here is to be wary when an atheist deploys the brute fact artillery. For those who start firing with brute facts typically do not understand that their shells will land on them as much as anyone else. In particular, they don't realize that the brute facts they deploy to destroy God will destroy the science they love so much as well.

Dalrymple on Original Sin

Theodore Dalrymple is always worth reading. Besides the grace of his prose style, he is remarkably Chestertonian in his ability to throw off phrases that capture succinctly profound insights. For instance, in his recent work Admirable Evasions: How Psychology Undermines Morality he writes this:

... for Man is not so much a problem-solving animal as a problem-creating one.

(Another reason for loving Dalrymple and his style is his refusal to bow to politically correct grammar. Thank God he didn't write "... for human beings are not so much problem-solving animals...")

What a wonderful encapsulation of the Doctrine of Original Sin! Dalrymple does not call it that and is not talking specifically about sin, but that doesn't matter. For what is Original Sin but the creation of problems where none needed to be created - in the Garden of Eden for instance? And how many of our problems - political, economic, cultural and personal - are not problems that descended upon us but instead are self-created?

It is an essentially conservative insight. If we are problem-creating animals, then we must constantly be on guard that in attempting to solve problems we merely create more.

Chesterton and Kierkegaard on the Difference of Christ

What difference does Christ make?

This question has many answers in many different contexts. Two of my favorite writers, G.K. Chesterton and Soren Kierkegaard, focus on the difference Christ makes in terms of human possibility.

Man is different from other animals insofar as he lives self-reflected in a world. Beavers and dogs don't worry about how they relate to the world; they just exist as they are unselfconsciously in the world. They are the world. But man knows himself as who he is in relation to the world. Kierkegaard describes this difference in The Sickness Unto Death in terms of the self as "a relation which relates itself to itself." The fact that man by nature relates himself to the world means his existence, unlike that of non-rational animals, is a dialectic of possibility and necessity. I understand who I am (or think I understand), and I also understand the world and my place in it, and in terms of that relationship life presents a present reality of necessity and a horizon of possibility. I exist as a relationship to the world, but I can know that relationship and (perhaps) change it - I can relate myself to the relationship which constitutes my self in the world.

But I can do that only in terms of the possibilities available to me, and those are constituted by my philosophy. What sort of possibilities are available to the natural but pre-Christian man, that is, the pagan man? Chesterton in Orthodoxy describes the pagan world as a world of pink. The great pagan virtue is moderation; a little of everything but not too much of anything. Red and white mixed together, not too much of each. This is a natural and sensible policy, and in the pagan world it produced great men like Aristotle and Marcus Aurelius. The ideal gentleman is a little bit of a warrior and a bit of a scholar as well. He drinks wine but not too much; he loves others but not too much of that either. For love is a form of madness and madness is unbalanced. Above all he maintains self-control, for he knows that the world contains good things as well as evil things, and that it ends in death. He keeps these facts before him and holds himself well so that he is neither carried away by good fortune, nor destroyed by misfortune, for life inevitably involves both. There is no better wisdom in a world without Christ, especially in a world that cannot imagine Christ. The life of balanced moderation is the best life that the best pagan mind could imagine; it defines the horizon of pagan possibility.

What has changed with Christ? The Gospel of John tells us that His first miracle occurred at Cana, and involved the replenishment of wine at a wedding feast that had run dry. We can assume that the host of the feast had on hand an appropriate amount of wine for the celebrations. It would seem, then, that any additional wine would violate the principle of moderation; we've gone from having a sensible good time to getting drunk in excess. But this is why it is a miracle, for a miracle is more than merely the suspension of ordinary physical expectations; it is a sign and revelation of a new order of existence, an order that breaks through the old pagan compromises and proposes a way of life that answers to the transcendent meaning of Christ. The exhaustion of the wine at Cana symbolizes the exhaustion of pagan virtue and the existential hopes it offered. The party is over; it is expected to be over and the celebrants are prepared to go home; no one can imagine the party continuing, or at least continuing with any propriety. But Christ can imagine it, and through His grace he turns water into wine, that the party may continue, theoretically indefinitely. From that moment forward the horizon of pagan hope has been forever shattered, for the possibility that it is not the final limit, that there is a way of life that is not bound by pagan compromises, has been permanently introduced into the human imagination.

Chesterton describes the difference as a world of pink becoming a world of bold reds and whites; reds for the warriors and whites for the monks. There were warriors in the ancient world, of course, and pacifists as well. But the pure warrior, like the pure pacifist, could not express an ideal human type because he violated the principle of moderation or balance. More significantly, the warrior and the pacifist had nothing to do with each other. Each might despise the other and, if they didn't, by the nature of things they at least expressed different philosophies of life. But in Christendom the martial Knight was as much an expression of the authentic Christian life as was the peaceful Monk. Far from expressing opposite philosophies of life, they both expressed different ways of performing the same mission: Redeeming the world in the name of Christ. Chesterton states the difference this way: In the ancient world the balance of existential possibilities was expressed in the single individual of the moderate, virtuous gentleman. In Christendom, the balance of possibilities occurred in the Church as a whole rather than individuals:

This was the big fact about Christian ethics; the discovery of the new balance. Paganism had been like a pillar of marble, upright because proportioned with symmetry. Christianity was like a huge and ragged and romantic rock, which, though it sways on its pedestal at a a touch, yet, because its exaggerated excrescencies exactly balance each other, is enthroned there for a thousand years. In a Gothic cathedral the columns were all different, but they were all necessary. Every support seemed an accidental and fantastic support; every buttress was a flying buttress. So in Christendom apparent accidents balanced. Becket wore a hair shirt under his gold an crimson, and there is much to be said for the combination; for Becket got the benefit of the hair shirt while the people in the street got the benefit of the crimson and gold. It is at least better than the manner of the modern millionnaire, who has the black and the drab outwardly for others, and the gold next his heart. But the balance was not walkways in one man's body ad in Becket's; the balance was often distributed over the whole body of Christendom. Because a man prayed and fasted on the Northern snows, flowers could be flung at his festival in the Southern cities; and because fanatics drank water on the sands of Syria, men could still drink cider in the orchards of England. This is what makes Christendom at once so much more perplexing and so much more interesting than the Pagan empire; just as Amiens Cathedral is not better but more interesting than the Parthenon.  - Orthodoxy, Ch. 6

For both Chesterton and SK, the advent of Christ permanently changed the nature of existence and of the world - and that whether you believe in Christ or not. The key point they share in this regard is that Christ revealed possibilities that were unimagined prior to the Incarnation. After the Incarnation, those possibilities cannot be eradicated from the human spirit, even if Christ Himself is later denied. The price of denying Christ cannot be a simple return to the pre-Christian world, for the possibilities he revealed will remain in the human imagination- it is only their fulfillment that will become impossible, since that fulfillment is only possible with the grace of God. The result is that post-Christian life can never be a simple return to paganism; it will instead be one of melancholy and despair.
