C.S. Lewis & Automobiles

I just read something funny about automobile commercials. This anonymous comment resonated with me, and may with you as well: “car advertisers grossly overestimate how much time I spend driving across the desert.”

It’s a versatile joke, since the final location is interchangeable. Despite the fact I live off a gravel road in the woods, they also grossly overestimate the time I spend summiting snowy mountains. Despite the “all wheel drive” in our two RAV4s,* I have no desire to race through dangerous or hostile environments.

Well, with one possible exception. I really enjoyed this entertaining advertisement from years ago. Trust me, watching this witty Jeep ad will be a worthwhile use of 31 seconds.

Cars are a ubiquitous presence in our world. In the States, getting a personal driver’s license is a traditional rite of passage for sixteen-year-olds. Even in many developing nations, automobile ownership is commonplace. While some urbanites consider the expenses associated with vehicles a foolish investment, most people find the alternative inconceivable. And, whether one owns, leases, rents, or borrows cars, having a driver’s license is a necessity.

That wasn’t always true. When my mother was learning to drive, the brakes went out on the car. She was so traumatized, she never drove again.

C.S. Lewis, on the other hand, had no interest in learning to drive. In fact, the brilliant Oxbridge professor was generally dismissive of automobiles. Presumably this did not carry over to his view of motorcycles, as his conversion while riding in brother Warnie’s sidecar attests.

On the Disadvantage of Traveling by Car

In his autobiography, C.S. Lewis declares “I number it among my blessings that my father had no car, while yet most of my friends had, and sometimes took me for a drive.”

The second half of the sentence makes ready sense. If our family lacks a car, it is fortuitous that generous friends compensated for its absence. But what could Lewis have meant by considering growing up without an automobile to be a “blessing?”

Fortunately, Lewis doesn’t leave us guessing—and his rationale provides a thought-provoking question. What might we sacrifice for the convenience of instantly accessible access to transportation that can carry us hundreds of miles in a handful of hours?

This meant that all these distant objects could be visited just enough to clothe them with memories and not impossible desires, while yet they remained ordinarily as inaccessible as the Moon.

The deadly power of rushing about wherever I pleased had not been given me [emphasis added].

I measure distances by the standard of man, man walking on his two feet, not by the standard of the internal combustion engine. I had not been allowed to deflower the very idea of distance . . .

The truest and most horrible claim made for modern transport is that it “annihilates space.” It does. It annihilates one of the most glorious gifts we have been given. It is a vile inflation which lowers the value of distance, so that a modern boy travels a hundred miles with less sense of liberation and pilgrimage and adventure than his grandfather got from traveling ten (Surprised by Joy).

This final idea of feeling adventure with modest travel opened my eyes to one of the “oddities” I experienced as a child. One year while I was young, my father was stationed overseas with the USMC, and my mother relocated us so we would be near her parents.

My grandparents had a practice that struck me, already a fairly well-traveled lad, as very strange. Each Sunday, after church, we would all pile into the family sedan and go for “a drive.” The cause for this special event was not to get from point A to point B. No, the purpose was simply to enjoy the simple experience of traveling. I don’t recall ever driving more than thirty miles from home, but setting out in random directions to savor the beauty of God’s creation did produce a unique type of satisfaction.

Human Perceptions of Distance

Distance can be considered in a variety of ways. We commonly think of distance in visual terms. Depth perception is made possible by binocular vision. Monocular (single eye) vision is poor at recognizing depths, although it can still be useful for comprehending distances and sizes. However, we are not reliant solely on our eyes.

An obvious alternative is found in the phenomenon of auditory distance perception. Not as efficient as its visual cousin, this medical article notes it does possess one significant advantage.

A normal-hearing person has an immediate appreciation of auditory space in the sense that orientation toward acoustic events is natural, rapid, and in general, accurate. Although spatial acuity is poorer by up to two orders of magnitude in the auditory than in the visual domain, the auditory world has the advantage of extending in all directions around the observer, while the visual world is restricted to frontal regions.

In “The Various Perceptions of Distance: An Alternative View of How Effort Affects Distance Judgments,” scientists discuss the even broader complexity of the subject.

Direct judgments of spatial relations are key to a variety of research domains, both inside and outside the discipline of psychology (e.g., spatial cognition, neuropsychology, exercise science, medical diagnosis, human factors). Thus, the lessons learned from this work have implications extending well beyond visual space perception.

Having noted there are psychological aspects of perceiving distances, I recommend QGIS. QGIS is a free, open source, cross-platform application which supports viewing and editing of geospatial data. It’s actually less complicated than it may sound, and a quick look at their “lesson” on “Spatial Thinking” is extremely informative.

“There are three fundamental concepts of spatial analysis: space, location, and distance.” Each of these perspectives includes absolute, relative and cognitive dimensions. It is the cognitive aspect that most fascinates me and, I sincerely believe, intrigued C.S. Lewis.

Absolute distance is a physical unit of measure, for instance, the number of miles between downtown Houston and downtown Toronto. Relative distance is calculated measuring distance, using metrics such as time, effort, or cost. For instance, the distance of two cities may be 2000 miles apart, which is an absolute description of distance, becomes the distance of two cities measured in tanks of gas, or mileage charge.

Last, let’s discuss the cognitive perception of distance. This refers to an individual’s perception of how far things are apart. For instance, to some, driving 200 miles between Houston and San Antonio Texas is a reasonable drive. However, for others, a 200 mile drive may seem like a very, very far distance to travel if they are not used to traveling such a distance regularly.

This final example, of the varying perceptions of distance by people with different experiences is precisely what Lewis identified in Surprised by Joy.

The truest and most horrible claim made for modern transport is that it “annihilates space.” It . . . is a vile inflation which lowers the value of distance, so that a modern boy travels a hundred miles with less sense of liberation and pilgrimage and adventure than his grandfather got from traveling ten.

Perhaps the Most Significant Matter of Distance

An article entitled “Closest Proximity And Infinite Distance” discusses Lewis’ insight into matters of distance. The author includes the following passage from Lewis’ Letters to Malcolm.

I fully agree that the relationship between God and a man is more private and intimate than any possible relation between two fellow creatures. Yes, but at the same time there is, in another way, a greater distance between the participants.

We are approaching—well I won’t say “the Wholly Other,” for I suspect that is meaningless, but the Unimaginably and Insupportably Other. We ought to be—sometimes I hope one is—simultaneously aware of closest proximity and infinite distance.

Once again, we witness C.S. Lewis’ brilliance. An awareness of both our Lord’s proximity to us and the vast distance between Creator and humankind, is a fundamental truth of Christian faith. And, here I will be bold in love, if either element is lacking in your personal relationship with God, I strongly encourage you to pursue such a balance.

C.S. Lewis and the Five Senses

On By robstroudIn C.S. Lewis, Christian Life, Education, Narnia, Potentially Useful Trivia9 Comments

One of the earliest lessons children learn is how many senses the human being possesses. You know the answer off the top of your head, right? Five. But, apparently, that’s no longer correct. Oh, you may think I must be including that long-time poser, extrasensory perception (ESP), which purports to be a sense of sorts beyond the five we all experience. If you thought that . . . sorry, but you are wrong again.

We all agree on the basic five: the faculties of sight, hearing, taste, smell, and touch. To this list, science has recently added several other senses we experience. They’re not actually new; Adam and Eve knew them too (with the possible exception of nociception). They actually make sense (in the other use of the word), as well. Here they are:

Proprioception – perceiving where your body parts are relative to one another, and the strength of effort being employed in movement

Thermoception – sensing temperature

Equilibrioception – perception of balance

Chronoception – sensing the passage of time

Interoception – feeling internal needs such as hunger and thirst

Nociception – experiencing pain

More expansive lists exist as well. Some are discussed online at The United Kingdom’s Sensory Trust. The Trust is devoted to “sensory design . . . [using] nature and the outdoors to improve the health and wellbeing of people living with disability and health issues.” They describe how “neurological classification” can result in numbers up to fifty-three. (It makes one long for the simplicity of the past when we followed Aristotle’s citation of only five.)

C.S. Lewis’ Celebration of Life

You can pick up nearly any one of Lewis’ essays or fiction, open to any page of his autobiography, read almost any of his letters, and you will see his love for nature. And Lewis is often quite vivid in his description of his encounter with God’s creation. The sights, sounds and smells he describes make the depictions real. Consider his description of Tash, the “god” worshipped by the Calormenes, in The Last Battle.

[King Tirian said] “What foul smell is this?”

“Phew!” gasped Eustace. “It’s like something dead. Is there a dead bird somewhere about? And why didn’t we notice it before?”

With a great upheaval Jewel [the unicorn] scrambled to his feet and pointed with his horn. “Look!” he cried. “Look at it! Look, look!” Then all six of them saw; and over all their faces there came an expression of uttermost dismay.

In the shadow of the trees on the far side of the clearing something was moving. It was gliding very slowly Northward. At a first glance you might have mistaken it for smoke, for it was gray and you could see things through it. But the deathly smell was not the smell of smoke. Also, this thing kept its shape instead of billowing and curling as smoke would have done. It was roughly the shape of a man but it had the head of a bird; some bird of prey with a cruel, curved beak. . . . It floated on the grass instead of walking, and the grass seemed to wither beneath it. . . .

[They] watched it for perhaps a minute, until it streamed away into the thicker trees on their right and disappeared. Then the sun came out again, and the birds once more began to sing. Everyone started breathing properly again and moved. They had all been still as statues while it was in sight.

From a more philosophical, even metaphysical perspective, Lewis ponders the senses experienced by angels in his poem, “On Being Human.” He describes the differences between how angels and humanity experience God’s creation. Lewis suggests that in exchange for their unblurred perception of cosmic reality, they lack the more mundane (i.e. earthly) experience of physical perception of creation.*

Angelic minds, they say, by simple intelligence
Behold the Forms of nature. They discern
Unerringly the Archtypes, all the verities
Which mortals lack or indirectly learn.
Transparent in primordial truth, unvarying,
Pure Earthness and right Stonehood from their clear,
High eminence are seen; unveiled, the seminal
Huge Principles appear.

The Tree-ness of the tree they know—the meaning of
Arboreal life, how from earth’s salty lap
The solar beam uplifts it, all the holiness
Enacted by leaves’ fall and rising sap;
But never an angel knows the knife-edged severance
Of sun from shadow where the trees begin,
The blessed cool at every pore caressing us
—An angel has no skin.

They see the Form of Air; but mortals breathing it
Drink the whole summer down into the breast.
The lavish pinks, the field new-mown, the ravishing
Sea-smells, the wood-fire smoke that whispers Rest.
The tremor on the rippled pool of memory
That from each smell in widening circles goes,
The pleasure and the pang—can angels measure it?
An angel has no nose.

The nourishing of life, and how it flourishes
On death, and why, they utterly know; but not
The hill-born, earthy spring, the dark cold bilberries
The ripe peach from the southern wall still hot,
Full-bellied tankards foamy-topped, the delicate
Half-lyric lamb, a new loaf’s billowy curves,
Nor porridge, nor the tingling taste of oranges—
An angel has no nerves.

Far richer they! I know the senses’ witchery
Guards us, like air, from heavens too big to see;
Imminent death to man that barb’d sublimity
And dazzling edge of beauty unsheathed would be.
Yet here, within this tiny, charm’d interior,
This parlour of the brain, their Maker shares
With living men some secrets in a privacy
Forever ours, not theirs.

This notion that we comprehend things the angels cannot—for example, the indwelling of God’s Holy Spirit—is expressed in the spirit of the First Epistle of Peter. These wondrous miracles are “things into which angels long to look.”

As amazing as our human senses are, we should never delude ourselves into thinking they are infallible. Far from it. As precious as they are, due to our fallen nature, they possess two shortcomings. First, they may misperceive reality. Such is the case with allodynia, in which a person “feels pain from non-painful stimuli,” such as a light touch or a cool temperature.⁑

The second limitation comes in the obvious fact of our finite nature. We are simply incapable of perceiving, much less processing, all the information that washes over us. Perhaps you would join me in identifying with C.S. Lewis’ description of himself in A Grief Observed.

Five senses; an incurably abstract intellect; a haphazardly selective memory; a set of preconceptions and assumptions so numerous that I can never examine more than a minority of them-never become even conscious of them all. How much of total reality can such an apparatus let through?

The number of human senses is not important. Our recognition of their divine source is, however, of eternal import.

* Chris Armstrong, Senior Editor of the Christian History Institute, wrote an exceptional article on the importance of our senses. Citing C.S. Lewis’ “On Being Human,” he declares our senses are the only means by which we can “know God.”

Nor is sense-knowledge about God through his Creation, second-class knowledge. Lewis expresses this idea memorably in his poem “On Being Human,” which compares the angels’ incorporeal way of knowing with our way—to the advantage of the latter.

The Christian History Institute publishes the exceptional Christian History magazine, which is offered for a simple donation. They also provide free, downloadable copies of past issues. I strongly encourage your support of this superb ministry.

⁑ From Medical News Today. “Some people feel extreme pain from something minor, such as a paper cut. Feeling increased pain or being hypersensitive to mild pain is called hyperalgesia. Individuals with allodynia, however, feel pain when something is ordinarily painless.”

Physical (and Spiritual) Deafness

On By robstroudIn C.S. Lewis, Christian Life, Education, Ministry, Writing16 Comments

kellerSome are born deaf. Others lose their hearing due to accident or illness. Still others find our hearing failing us gradually, as it is displaced by the persistent presence of that unwelcome visitor, tinnitus.

As I was pondering the slow decay of my own hearing, I recalled one of C.S. Lewis’ most brilliant insights.

We can ignore even pleasure. But pain insists upon being attended to. God whispers to us in our pleasures, speaks in our conscience, but shouts in our pains: it is his megaphone to rouse a deaf world. (The Problem of Pain)

Even as I am concerned about the inevitable decline of my hearing—and more so, my vision—I try to conscientiously follow my wife’s guidance about vitamins and behaviors that will keep these senses around as long as possible.

At the same time, being a realist, I have decided to disengage my emotions from the matter as much as I am able, and simply accept the unavoidable. In fact, I have learned to enjoy some of the inaccuracies of hearing that I more and more often experience.

Hardly a day passes when I do not get a good laugh out of something I misheard. What I mean is that my brain translates the garbled sounds into actual words that constitute some sense that is in reality nonsensical. It hasn’t cause any problems yet, so I just smile or chuckle. If the mishearing is especially humorous, I sometimes share it with my family.

Recently, I smiled when my pastor went on about how great “Lutheran circuses” are, and how important it was that we invite others to attend our “Lutheran worship circuses” (services). That substitution was easy to recognize; it’s far funnier when I mishear something and what I think they said makes an odd sense that could almost be true . . . but is actually ludicrous.

I don’t share my personal way of dealing with the weakening of my sense of hearing with the intention of belittling the seriousness of a cross many have to bear as their lives are detrimentally impacted by these afflictions.

The Original Plan

Certainly, the impairment of any of the senses God has given us is cause for sadness. After all, when our first parents were created, their senses of sight, hearing, touch, smell and taste were undiminished. That’s the way that the Lord intended for us to enjoy the rest of his creation.

Actually, some people argue that there are seven senses, adding two that do make sense:

Vestibular – the sense of balance, perceiving our body in relationship to gravity and movement (equilibrioception)

Proprioception – the sense of the relative position of different parts of the body, particularly as it pertains to movement (kinesthesia)

Another source declares there are nine senses, adding to the palette

Thermoception – the sensation of the presence or absence of heat

Nociception – “nonconscious perception of nerve or tissue damage”

I personally imagine that when “the day of the Lord” arrives, and we witness the restoration of a new heaven and a new earth, that our restored bodies* will possess a myriad of other senses we are not even capable of fathoming at this present moment.

Yes, it is a tragedy when people have to live with their senses crippled. This is especially true when it is the young who are afflicted. To be born without sight or hearing rightly seems like a curse to many. The testimony of Helen Keller, who actually lost her vision and hearing at the age of nineteen months, illustrates how the human spirit is capable of transcending even these severe limitations.**

In 1952, C.S. Lewis wrote a letter to a young teacher at the Manchester Royal School for the Deaf.

The work you are engaged in is a magnificent one (much in my mind because, as it falls out, I’ve just been reading Helen Keller’s book): hard, no doubt, but you can never be attacked by the suspicion that it is not worth doing. There are jolly few professions of which we can say that.

The translation of great stories into a limited vocabulary will, incidentally, be a wonderful discipline: you will learn a lot about thought and language in general before you are done. I hope you will sometimes let me know how you get on. God bless you.

In writing this column I learned something of which I had been unaware. Keller was also a poet.

And, while I’m a poor judge of verse, I found my brief exploration of hers to be moving. However, here is a review from The New York Times which declares, “Modern psychology cannot account for Miss Keller nor explain the psychic sense by which she apprehends the minutest phases of a beauty she has never witnessed.”

You can download a copy of the book The Song of the Stone Wall, here.

Across the meadow, by the ancient pines,

Where I, the child of life that lived that spring,

Drink in the fragrances of the young year,

The field-wall meets one grimly squared and straight

Beyond it rise the old tombs, gray and restful,

And the upright slates record the generations.

Stiffly aslant before the northern blasts.

Like the steadfast, angular beliefs

Of those whom they commemorate, the head-stones stand,

Cemented deep with moss and invisible roots.

The rude inscriptions charged with faith and love,

Graceless as Death himself, yet sweet as Death,

Are half erased by the impartial storms.

As children lisping words which move to laughter

Are themselves poems of unconscious melody,

So the old gravestones with their crabbed muse

Are beautiful for their halting words of faith,

Their groping love that had no gift of song.

But all the broken tragedy of life

And all the yearning mystery of death

Are celebrated in sweet epitaphs of vines and violets.

Helen Keller’s life is a witness to the fact that God can intervene in our brokenness and make us whole. It is also a foretaste of that complete restoration that awaits disciples of Jesus on the Last Day.

And one more thing her life proves is the truth of C.S. Lewis’ insight that in our suffering we become more attuned to our need, and God “shouts in our pains: it is his megaphone to rouse a deaf world.”
