Reason & knowing
It is the received view, up here in the High Doganate, that we do not know what we do not know. Granted, this is a peculiarly Catholic view, & may therefore smack of sectarianism; but we cannot find an alternative to it that is at all convincing. We puzzle upon Mysteries that were simply “given,” entirely beyond human comprehension. Not only “we,” but I. The little I know with any certainty has come mostly from that exercise, both inside & outside religion; for though natural mysteries are different in kind from theological Mysteries, they have a similar impenetrable quality. In fact, they deepen, the more that we learn.
This is not so simple a matter as not knowing the answers to empirical questions, such as by what means creatures of one species metamorphose into creatures of another. True enough, having rejected as glib the suggestion of “natural selection,” I have nothing whatever to replace it with; but that is only the beginning of my ignorance. And it is not something I need to know. People lived for centuries without knowing the Earth went much more around the Sun than vice versa, yet the sunsets were the same. They could even make accurate astronomical calculations, on a wrong model of the solar system. With the right rocket technology, but that wrong model, we could have landed a man on the moon. So who really needed Copernicus? (Well, he simplified the math.)
A more fundamental ignorance would be, “What is it that I need to know?” For this would involve cutting through far worse misdirections than were supplied by Claudius Ptolemy’s astronomy, & thus much harder mental work.
Faith comes into this equation, in the most elementary sense, because a few things I obviously do need to know come to me via “penny catechism,” the way the alphabet used to come to children through penny broadsides. I can’t think of any other way the most basic theological, philosophical, & even logical propositions could have reached me, than by flat instruction, for none could possibly be discovered through trial & error, by any isolated man working entirely from scratch.
And since one proposition depends on another, it is very much like the problem of the first biological cell. It involved a number of coordinated propositions, & could not have been assembled one bit at a time. (Only inanimate structures can be assembled like that, solid brick over solid brick, & even then one might be living in Christchurch where the ground liquefies from time to time.)
Instead, I am thinking of the “higher,” or at least, most complex propositions, in what seems like the No Man’s Land between what we need to know, & what we don’t. The perfect example, to my mind, is the apparent answer to a prayer. Is it God’s answer, the Devil’s answer, or just my own stupid projection? I will not vex the reader in this case with several dozen subsidiary questions. In only one, or perhaps two cases in the course of my life could I be reasonably sure. In the others, “I don’t know” would be indicated, together with its moral corollary, “Proceed with caution.”
An example might clarify what I am babbling about here. Once, just after the death of a very close friend whom I’d been attending, I pleaded with God to give me a glimpse of what happens immediately after death. And seemingly in response, I had something like a vision, of my friend Bob having passed through a door still slightly ajar, to a place that was like Earth, but with spatial & temporal dimensions transformed, & a light all-suffusing. And with that, a feeling of peace, that we will know the place; that it will not be entirely foreign to the human. But was this a genuine or a false vision? I do not know.
Note that I am not attempting some radical Cartesian or Baconian or Humean or Kantian critique of reason. As a penny-catechized Catholic, I accept reason more or less at face value. If it looks like a duck, walks like a duck, quacks like a duck, & has the right ambiance, it may be safely labelled. Should it turn out to be a swan, I will change the label, but it will take some work to convince me. Generally speaking, reason is serviceable, unless one’s own misconceptions (about ducks, for instance) get in the way. Generally speaking, the more checkable information one has, the more one knows. In this case, the more one even knows about how the duck looks back at you, & sizes you up. For I am not sceptical of the empathetic reason, though I know it can take us only so far. The Other is the Other after all, even when it is a duck. But ducks & we have a few things in common.
People should realize that the modern attack on Reason came with the Reformation. (Many previous attacks, but none so materially successful.) The notion that reason itself is twisted, & must be rejected as collateral damage from the Fall of Man, provided much of the theological fuel with which torchings of Holy Church were attempted. She had for her part embraced reason from the beginning, as one of the very tests for the “fallenness” of Man. Reason is of God; it is men who are unreasonable. Because we are unchaste, because we do not pursue reason chastely, because we twist it to get the results we want. This, however, is a problem with us. It is not a problem with reason.
Reason, of just this chaste sort, plays a very large role in day to day religion. Let us now take the Sacrament of Penance — “Confession” — for an example, suitable to Ash Wednesday. Preparing for Confession, I may consult some standard list of mortal vices, under headings such as Pride, Envy, Greed, Lust, Wrath, Sloth, Gluttony. But often one is not quite sure, not merely what heading to choose, but whether what one did was really a sin. And from the best spiritual advisers, it turns out the next question isn’t, “What did it feel like?” That is Pride’s bottomlessly subjective dissertation, the one in which we all love to wallow, gluttonously. The question is instead much plainer & more objective: “What did it look like?”
For reason in this case involves a simple out-of-body exercise. Stand outside & look in, as if you were not you, but an impartial, external observer. If it looked like a sin, walked like a sin, quacked like a sin, & had the right ambiance, you have almost certainly got in nailed. The fact you felt badly when you were caught need not come into it.
(This is something I love about the Church’s teaching on sin, & all the liturgical & other practices that follow from it. It is not emotional & theatrical. It is instead logical & reasonable. Nor does it fantasize that men will, as a regular habit, make full & adequate confessions to God. Knowing what men are, the Church isn’t so easily suckered.)
There is plenty we can know by reason, even without the use of statistics. There indeed must be more that we can know by reason, than we do know, for new things are discovered in the same old data. That, incidentally, is how Catholic doctrines may develop, over time. It is the same old doctrine from the start, but from new experience we suddenly discover an implication we had not seen before. The doctrine in this case has not “changed”; it has instead been more completely comprehended.
The worldview, in which we try reason first, & fight our lazy fatalist habits, is different in kind from the worldview in which everything that happens is attributed to djinns. As Western men & women, we inherit this “rationalist” propensity, perhaps from pagan Greeks, who pioneered in this territory. But the Greeks themselves knew reason was not something they had made, rather something they had discovered. They also knew it was intrinsically divine.
Reason comes down to us, immeasurably enhanced, because the Church bought into it bigtime, from even before the Pauline generation. It is there in Christ who, directly in the Gospels, unhesitantly applies the sharpest reason to the clever people trying to entrap Him. And it has been taught, as part of the “core curriculum” through twenty centuries, so that by now the intellectual heritage of the Greeks — Plato, Aristotle, Theocritus, &c — is inseparable from our Catholic Christian heritage; spliced into the framing of the bark, so to say. (It wasn’t just the recovery of Aristotelian texts from the Byzantine Greeks through the Arabs; for such as Origen & Augustine had already been fully engaged.)
And I left out Socrates who, quite apart from the biographers & admirers through whom we try to “read” him — for like Jesus of Nazareth he wrote nothing down — comes closest to anticipating the Christian point of view, starting from reason. That we learn by direct inquiry; that we start by admitting what we don’t know; that the pursuit of truth requires not just the mind but the whole man. That, reason & unreason war within each human heart. Where, unreason masquerades as reason. That, ideas have consequences in life. Where, they are passed from man to man. That, “philosophy” being not merely thought, but lived — is something profoundly personal.
From a position of real acknowledged ignorance, & proceeding by steps of reason, Socrates was able to get a considerable distance. By pursuing such concepts as “justice” — ruthlessly, in a sense — he came remarkably close to the Christian idea of God. He did not get there. Nevertheless, he taught Plato, & through Plato, Aristotle, things that to outward appearance no merely rational person, even an ingenious Greek, had any business knowing. Being Socrates he stopped at what he could not know. But what he knew, he knew; & he drank the hemlock rather than agree to what he knew was wrong.
Revelation takes us well beyond Reason, yet it is reason that leads to revelation’s door, historically as well as in every other sense. For even in assimilating the content of “Scripture & Tradition” we need minds, to test. It could not be genuine Revelation unless it made sense; unless it was internally consistent & externally coherent; unless we could be sure that its consequences were not trivial or absurd.
From the beginning, the Church rejected such theological try-ons as “by faith alone,” unless that faith was consistent with reason; or “by scripture alone,” knowing the very canon of Scripture required prayerful reasoning to discern, & prayerful reasoning to interpret. For she began her work even before there was a New Testament; being founded not on Scripture, but in Christ. (But of course everything is in practice checked against Scripture, & has been ever since it was available. Every papal proclamation of which I am aware — quite a few by now, including many quite ancient — has been utterly crawling with scriptural references & allusions.)
The Old Testament served the first generation, & was pre-eminent for several more. The earliest Fathers of the Church, as the Rabbis before them, were fully aware that Scripture is replete with things crying out to be misinterpreted by the perversity of men — who aren’t Saints; whose reasoning is neither chaste nor humble; whose learning is seldom even skin deep; & who in the event are seething, not with charity but with anger. Scripture could be twisted against itself — it was often so twisted before their eyes. Every day, to this day, we may watch men turning the screws on reason: big-brained “reformers” who are puffballs of spite; making rules from which they are self-exempted.
And that is precisely why we read Scripture in light of Church teaching — the cumulative interpretive wisdom of so many hundred years. For two millennia now, the Church has had the delicate task of disowning her fanatics, & putting their djinns back in their bottles; of consolidating & teaching, instead, what can be known among reasonable men, who will consent to learn before they try teaching, & are of an instinct to reverence what they have inherited.
For Revelation, too, takes us only so far. It tells us what we need to know, but not everything we want to know. As human beings — fundamentally flawed, yet also strangely exalted in the image of Christ — we characteristically push at the edges. We ask for precision where only approximation is available to us, or analogy from what we have seen; we demand answers to questions that we cannot even formulate coherently. We ask, always, for more than we can get, & as a trading race, think we can negotiate. A proud race, too, we are always bluffing, especially to ourselves. We almost invariably think we know more than we do — until our ignorance is exposed, if not well after.
One of my own Lenten resolutions this year is to find contentment; not only in what I can eat & drink; in what I must do for penance, & give for alms; but also in what I can know. To shake off, if only for a season, this curiously modern neurosis, that aspires to superhuman knowledge, & blinds one not only to what can be known, but even to what is known already. (Or was this not the first mortal sin, of Adam?) To go, ideally, forty days & nights without trying to make any Faustian bargains.
Some of the readers of this blog may find the book The Belief of Catholics by Msgr. Ronald Knox of interest. Ronald Knox was a brilliant man and a convert to the Catholic Faith. This book provides, among other things, proofs for: i) the existence of God, ii) the fact that Christ is God, and iii) that Christ established the Catholic Church.
It is a peculiar perversity of the modern age that so many wish(ed) for such knowledge as can only be had by a mind not human; that is, one free from the marks of embodiment, history, language, prejudice of every sort — in short, free from the very things that make what little knowledge we do have possible in the first place. One should wonder why that sort of “knowing” holds any appeal at all.
St. Augustine calls an appetite for knowledge that is not ruled by charity, “curiositas.” I think you do well, Mr. Warren, to argue along with him that we should think carefully about the question, “What is it that I need to know?” With so many (myself included) finding themselves slaves to their appetite for knowledge (we flatter ourselves by calling it knowledge), the call for thoughtful moderation is timely.
And what is a smartphone, if not another disguise of the charming and ruinous Mephistopheles?
“Every day, to this day, we may watch men turning the screws on reason: big-brained ‘reformers’ who are puffballs of spite; making rules from which they are self-exempted.”
You see this where you would least expect to see it: in the sciences, or more precisely in the scientistic philosophies masquerading as science: where something comes into being from a nothing that looks an awful lot like a something, where the self, which does not exist, occupies itself with attempting to prove this very point, where all thought is suspect except the thought of the one thinking that same thought. These inhuman philosophies were spawned by the irrational ideologies of sola scriptura and sola fide. Now, the bible (or faith)-only crowd does battle to the death with the physics-only crowd, one fundamentalism cut off from the Logos pitted against another, as is only fitting. “In the beginning was the Word (Logos).”
Mr Warren, I wonder if your vision of heaven is similar to that described by Dr Eben Alexander in his book, Proof of Heaven.
Mr Disque, I don’t know that either, never having seen the book. You’d be amazed how many books I haven’t seen, let alone read. They would fill a very large library.
(Perhaps I should add, that I hadn’t asked for a glimpse of Heaven, but only as it were to the “foyer” — to the first place after the last place on Earth, one footstep over the boundary. By his own estimation, the chances my friend would get directly into Heaven were anyway less than remote. I’m generally inclined only to take Christ’s word on what Heaven is like, as the source likeliest to be well-informed. Granted, this only shows the propensity of an old hack journalist. But Christ didn’t spend a lot of time down here describing it, & what He had to say beyond the Gospels was not reliably recorded. Other accounts are quite varied, & seem to depend on analogy, or hearsay. So let us get to Heaven, & see what we can see!)
A few years back I was having a discussion with a lapsed-Catholic-turned-Buddhist.
“Catholicism has always opposed itself to scientific progress,” the fellow told me with supreme and aloof confidence. “Just look at how badly the Galileo situation was handled. It was a clear case of robed men once again suppressing progress under color of authority.”
“You sure are credulous,” I observed.
“Hardly,” he replied insouciantly.
“Then why can’t you come up with another example?” I asked. “If the Catholic Church is and always has been fundamentally opposed to scientific progress, then you should be able to come up with twenty centuries worth of examples. Yet somehow, you keep coming back to just one, and that one is five centuries old to boot.”
“You can hardly expect me to offer a proof of a negative,” the chap serenely whined. “How can I come up with examples of what has been permanently buried and done away with?”
“Well that’s sure convenient for your case,” I said. “You’ve made a sweeping generalization, and then you’ve offered no proof or evidence to back it up. How scientific is that? In my experience, an unsupported generalization is best met by a categorical denial.”
“Of course you would say that,” he smirked, “you’re just sticking to the party line.”
Of course.
One of my unpublished books is a compilation of 100 Catholic scientists — individuals who were not only men of faith and men of science, but whose faith helped lay the intellectual foundation for their scientific efforts. There are many more that could be named, but 100 seemed like a decent number to work with; at that number, it’s already a longer list than the Buddhist equivalent.
Er, perhaps I should now add, to Mr Disque, that on Google-searching I realized that I had read all about Dr Eben Alexander the neurosurgeon’s experience, months ago on Internet, then dropped it out of mind. I see that since he has attracted a lot of vitriol from Sam Harris & the rest of the Atheist Inquisition, while travelling to the top of the New York Times bestseller list.
While “the enemy of my enemy is my friend,” I am at a complete loss what to make of such claims. There are many, & they seem to resemble one another, in a hypnagogic way. I find it hard to believe that everyone goes straight to Heaven. Why does no one ever go to Hell? The very claim to be offering “proof” smacks of cultural conditioning, by scientism. I’d find it easier to believe that some vivid paradisal notion were implanted in the structure of the brain, & accessed in extreme trauma; but that is wild speculation. We know far less about the brain than we think we do. “Brain death” is itself not a clear concept, given that apparently dead brains revive.
Indeed, the best definition I’ve heard was presented by a surgeon working in the old Westminster Hospital, in London now 37 years ago. He was driving a spike into my chest at the time (with a tube threaded through it: I’d suffered a spontaneous pneumothorax); & I was determined to impress a pretty nurse at the foot of the bed. So I tried to engage him in bantering conversation, as if I were indifferent to pain.
“I’m curious to know how ‘brain death’ is defined around here,” I asked.
Between heaves on the spike, against my highly resistant pleural wall, he dealt with this pointless distraction.
“Well, Mr Warren, … [heave] … at Westminster, our tentative policy is … [heave] … to consider as so-to-speak ‘brain dead’ … [heave] … any patient who fails … [heave] … to respond to the command, … [heave] … ‘Wake up you effing zombie!’ …”
(The bugger knew that laughter would cause me excruciating pain.)
I think too many Christians are obsessed with discovering if God exists, a pursuit that appears blasphemous. Who really needs something like the Shroud of Turin to be proven authentic? If that is what one’s faith rests on, it is likely not very strong. Same goes for disproving nonsense like Darwinism. If one is genuinely interested in science, that is one thing, but if the interest stems for a need to pile up evidence in favour of God, then again there is a problem. God created science; He is not a byproduct of it.
Once a Protestant friend signed me up at his own expense to a recent-Creationist propaganda magazine that came about once a month in the mail. I hardly read the rag at all because it featured bad science articles and also had a tone about it that seemed hysterical. I gave the magazines away to a Catholic friend who was interested in science, and much to my surprise, he became obsessed with it. For some reason, known only to himself, he simply had to believe that the world was about six thousand years old. Later I learned that this Catholic friend believed that the sun orbits around the earth. (I’m not making this up.) When I found this out, I told him that for all I cared, the universe orbits around the tip of my nose. (He was quite offended, but I really didn’t care.)
I think we are tempting God indeed when we set out to prove His existence or discover what we have to accept on faith. We are only given enough knowledge to be saved. We can study anything we like as much as we like, but we really have to be careful to remember that our reason can be easily hijacked by a force that wishes us ill, not good.
Viscount Dorchart, thank you for that last comment. I am one of those who sometimes tries to pile up evidence in favor of God. For a while I have been feeling that this is like discussing with Mormons or Jehovah’s Witnesses. Socialists and Darwinists are not much different from them. Your friend that fell for the 6,000 year old earth argument is a mild case of the same. I have proved the existence of God to myself and I can defend the truth of the Gospel as it is my duty. I think I am going to start walking away shaking my head at all the nuts and fools that travel with me in this crazy planet. If the Lord does not come soon I hope at least He teaches me how to live with this crowd. Your approach seems pretty good to me. I’ll see if I can implement it here. Truly one can get too involved in these cultural fights. Sometimes we do not need arguments, we just need some light.
David, feel free to delete this as I really don’t want to start up the old argument once again, but it struck me (I’m slow) ruminating on the last exchange regarding Darwinsish things and reason, that natural selection can only be subtractive. It can only pick from an array of characteristics on offer. All the work is done by mutation. The eyeball and the human brain was made by mutation in the scheme that the Darwinoids propose. Maybe I should write it as Mutation. Why don’t they call their concept “magic mutation” instead of natural selection?
As you noted above, certain “systems” in nature are irreducible. DNA can’t exist without RNA as one small for instance. So Mutation must have a plan. It can’t be random. Natural selection is self-evident. Things that work do better than things that don’t work in all fields of endeavor. The deep and profound mystery of the world of the flesh is Mutation. Mutation can’t be random because of the existence of mutually contingent processes that appear suddenly and that can’t be reduced to individual components and still exist.
As I said, I’m slow. I’m sure the Darwinoids have a ready answer. I just can’t imagine what it would be.
Other Joe, the Darwinists will respond but they don’t really have an answer that makes sense. To have the right mutation that has to be represented as information in DNA. The question remains as how the original representation of a tri-dimensional organism came to be represented in the DNA model for the first time and then how multiple beneficial mutations came to be represented there first. The problem becomes a semiotic problem of chicken or egg.
Fr. Peter Scott is a priest of my acquaintance who was in medicine before entering the seminary (incidentally, Father is just down the road from you in New Hamburg). He wrote an essay on the subject of brain death in which he cited a review of the literature on the topic in New England Journal of Medicine article (Truong & Miller, New England Journal of Medicine 14 August 2008 issue, vol. 359 (7), p. 674-675).
The NJM article observed that “brain death” as practiced today is an arbitrary criterion which cannot be supported by any kind of objective method – to wit, “The arguments about why these patients should be considered dead have never been fully convincing…the [Dead Donor] rule has provided misleading ethical cover that cannot withstand careful scrutiny…the uncomfortable conclusion to be drawn from this literature is that although it may be perfectly ethical to remove vital organs for transplantation from patients who satisfy the diagnostic criteria of brain death, the reason it is ethical cannot be that we are convinced they are really dead.”
The harvesting of a necessary organ like the heart is done with a patient who is still living; the act of removing their heart is what kills him. Padre’s conclusion was that the medical profession has been guilty of “gerrymandering the definition of death to carefully conform with conditions that are most favorable for transplantation.”
The NJM article drew the flawed conclusion that for the sake of expediency the current practice of organ harvesting is still ethical – i.e. essentially on the grounds that death is immanent, which is another arbitrary standard. Certainly the current practice saves lives; one life is taken to preserve another; it is, I’m, sure, quite gratifying to the egos of the Übermensch. Then again, organ harvesting is big money.
Viscount Dochart asks the rhetorical question, “Who really needs something like the Shroud of Turin to be proven authentic?”
Not the Catholic Church, which has said that it has no opinion on the subject. If individuals find that acceptance of the Shroud as genuine quickens their faith, good for them. But there is nothing in terms of the Faith to compel acceptance of the Shroud. Contrariwise, there is nothing about the Shroud that undermines or harms belief either.
Now, for those who are already convinced of Christ’s Divinity and have become His followers, the Shroud can be an item of wonder. Catholics have long been inclined to observe that different persons, places, times, and objects have significance that is dependent on their relation to Christ and what pertains to Him. Many of these are consecrated: specifically set aside for sacred use.
* Persons: the Pope, clerics, religious, saints
* Places: a church, Rome, the Holy Sepulchre, numerous pilgrimage spots
* Times: the liturgical seasons, the daily hours of the Divine Office
* Objects: the Bible, altar, chalice and ciborium, monstrance, relics
All of creation is pressed into the service of the Almighty. Pious souls have long been creative in what they have adopted into the service of God. The Shroud, then, is potentially just one of many reminders about what Catholics believe and why. Generally, items associated with Christ’s Passion are given greater regard and shown more reverence than the rest. One need not rely on the Shroud to become a convinced disciple; those who are convinced, meanwhile, can recognize the value of an item like the Shroud.
Buisius, I thank you for your recommendation of The Belief of Catholics. Out university now, I continue to realize that somehow I spent four years not reading the right books: apparently my beloved professors thought other volumes more appropriate. Perhaps I was just not paying attention. I take it that happens to many a young man away at college.
Along those lines I thought I could mention what I decided to “give up” for my first Lenten observation: my mornings. I am currently preparing to go to graduate school (a.k.a. working as waiter for the next six months), therefor I happen to have the luxury of not exactly having to be anywhere before noon on any given day. I have removed myself the option of sleeping in past sunrise. With all this extra time, I suppose I will have the required hours available to study what is actually important.
So by all means, keep the book recommendations coming.
Other Joe, my most charitable interpretation of the Darwinian “vision” — rather like some of mine, but less religious — would be: “Less is more!”
But it is true we have persecuted Lord Acartia enough. Having played Lone Ranger without a Tonto among whooping Darwinoids so often, I almost identify with the isolated Darwinist among this chine of chittering Aristotelian polecats.
Other Joe, I also don’t want to reopen the debate, but I just thought that I would offer one point. In a strict statistical sense, mutations are far from being random. There are some parts of DNA that are far more prone to point mutations than others.
It may be true that DNA can’t survive without RNA, but RNA can, and does, exist without DNA. In fact, there are life forms that do not have DNA. There are some theories that the earlier life forms were RNA based rather than DNA based.
David, thank you for returning my Lord status.
Acartia, it is provisional. We have granted you a barony, with a saltpond, so you may raise your little calanoid copepods in peace, but we expect you to remain on civil tea-drinking terms with the vicar.
David, you don’t realize how appropriate your comment is. I am in the process of setting up my first ever saltwater aquarium. I am sure that it will have its share of calanoid, cyclopoid and harpacticoid copeopods.
Well, then, my greetings to all your wee crustaceans, planktonic, benthic, or even terrestrial, without prejudice; & peace unto all species of goodwill.
Now that we have dispensed with the niceties, it may come as a surprise that I agree with much of what David has said here, or, as much as I understand.
It is obvious that there are things that we will never know. We will never know with certainty how the universe started; we will never know with certainty if natural selection accounts for the diversity of life we see now and have seen in the past. We will never know with certainty how life originated. Even if scientists are able to conduct an elaborate set of conditions that result in a life form, we will never know if this is how it happened, only that it could have.
Every person, every scientist, every clergyman, every pope and, yes, even David and I, are affected by bias when they attempt to reason. An intelligent person is one who understands this. Two people observe the exact same things will interpret them in different ways, their conclusions being affected by all of their previous experiences. That may be why the hardest audiences for illusionists is children. They are less hampered by the baggage.
It is this preconception and bias that results in people becoming more recalcitrant as they get older. It is also why we have paradigm shifts in science. The entire scientific community gets involved in group think that requires much evidence to shift. Plate tectonics were not originally accepted. Dinosaur killing asteroid was not originally accepted. Natural selection was not originally accepted. And, it is possible, that one or all of these may undergo a significant rethink in the future. But these concepts do not persist because of any conspiracy. Conspiracies, especially in science, are not possible. Every scientist that I have ever known would sell their soul (if they had one) for evidence that would disprove a generally accepted theory. Even though their evidence will be questioned, and sometimes emotionally, but it will be examined. If it is sound, it will slowly grow legs.
Mark Antonio, regarding reading matter, a good start would be anything by CS Lewis, the great GK Chesterton or Hilaire Belloc (Lewis was C of E, but very sound). Of modern novelists I would recommend Piers Paul Read (his non-fiction book ‘Hell and Other Destinations’ demonstrates well his traditional orthodoxy) and Walker Percy, two sound members of the Holy Roman and Apostolic Church. I’m sure David or many of the other learned commentators could come up with far more suggestions than me.
It is possible for one to obtain certain evidence of God’s existence, and it’s not even presumptuous to do so. Here’s how you do it: you ask Him. Something like,
“God, if those loopy Catholics are right about you, then I’m sure you can prove it to me. I am asking you to do so. If you are out there like they say, and you love me like they say, I want to know.”
It isn’t presumptuous because God does in fact love us, and wants us to know it. However, there is a condition and a caveat or two. The condition is, God will not prove his existence to you unless there is nothing more important to you than knowing the truth of his existence. The caveats: first, he is neither obligated to provide you with evidence that will convince others, nor is he constrained to do so. Second, there are likely to be some things which you hold dear, that you will have to give up.
I have actually read several books on the Shroud of Turin. It’s an interesting historical artifact, but I doubt if it is authentic. Christ was resurrected in total from this earth. I doubt if he left anything physical behind that he wanted to see discussed in the pages of National Geographic.
As for my comments on Christians who try to disprove a crackpot like Darwin, please do not use more crackpottery to attempt to do so. If you must discuss the wretched theory of the god of left/liberal atheist polemicists everywhere, please take as your esteemed example King David of the High Doganate. He has probably read more on evolution and biology than Ezra Pound read poetry before and after he met T.S. Eliot.
I once had a discussion with a dear friend who also thought we should not argue about the existence of God — if Jesus had wanted us to do so, could he not have given us the ultimate proof? My response was and is: he came to earth, performed miracles, let himself be killed and then rose from the dead, how is that not proof? Of course, one must have a certain element of faith first.
I feel obliged to point out that while Luther indeed railed against human reason, both he and Calvin (Calvin more explicitly so) actually took more of an Augustinian stance (in practice) where reason on its own could not be trusted, but only reason grounded in the words of God. One cannot read Calvin’s works without being impressed by his logical (rational) abilities, even if one disagrees with his conclusions. What they did do (and what most of this audience disagrees with) is remove Tradition from being a likewise dependable pillar of reason — not necessarily an incorrect position to reason from, just … proceed with caution.
As for the 6000 year old earth versus the 4.5 billion year old earth, … it strikes me that often those who feel and argue strongly on either side fall into the same “scientistic” trap (bad science abounds on both sides! I’ve read some crazy young Earth theories, but I’ve also read up on evolution), despite it having basically no relevance to anything that really matters. All known natural laws can be derived from a much shorter time scale (or we wouldn’t know them!), and all invention, research, science, etc. can be driven from those theories. To a Christian, these laws will come to an end unpredictably (the day will come like a thief in the night!) no matter the length of their history, and to a non-Christian, that day will be an even bigger surprise.
The whole “argument” is usually just a cover for one of two questions — does God exist? And do you agree with science? The former is discussed above (yes, He does, and no, I don’t have to prove that, I know it. … If you need proof, look around you and ask Him to open your eyes). The latter is usually a cover for a snarky “or are you one of those Bible thumping American hill-billies who actually believe that God exists and men had dinosaurs for pets?” A question asked in bad faith to tar the other person as ignorant and build oneself up as intelligent. Refusing to engage in the discussion of course puts one in the same category as giving the “wrong” answer. Judge a person by their fruits (or even better, judge the fruits, not the person), not based on their best guess as to the age of the Earth in terms of how many times it has spun around the Sun!
