A Rocky History Read Backwards

Writers in Western culture have long employed the metaphor of a "book" for depicting the natural world, with we being "readers" of that "book."  Theologians in both Christianity and Islam have said that the "Book of Nature" might even speak to us something about God.  It was a famous scientist, however, who in 1859 drew upon the "book" metaphor to explain an aspect of the geological record.  In Origin of Species, Charles Darwin wrote:
"I look at the natural geological record... as a history of the world imperfectly kept,
 and written in a changing dialect; of this history we possess the last volume alone....
 Of this volume, only here and there a short chapter has been preserved;
 and of each page, only here and there a few lines."

Darwin was having to explain why -- unlike, other books that we haven't finished reading -- we know more about the last pages of the book of the Earth's geology than about the first.  Today, geologists have succeeded in reading more and more of those pages, going further and further back, despite the fragility of many fossils, and the fact that fossils were created only under special circumstances.  This geological "history book" is being read from the back towards the front.

Almost like glass.
It was not along a book-like, historical narrative that I first encountered the science of geology.  Instead, I first experienced the identity of rocks in compartmentalized categories. When I was of upper elementary-school age, I was given a boxed set of rocks.  It consisted of a white, plastic tray of 15 thumb-size rocks, each one in its open-topped compartment.  The makers of the set, knowing that children would want to take the rocks out of their cubbyholes, wisely managed to adhere a small, identifying nametag to each rock.

An intense yellow.
 I found the differences between those unpolished rocks fascinating.  White gypsum.  Yellow sulfur.  Black coal.  Even the feel of each one was different.  Despite that childhood enjoyment, when I had some brief encounters with geology books in high-school and college, I could never get the rocks to "speak" to me.  When those books tried to explain geological history, I could not create a powerful enough mental picture because those geological layers were out of sight, underground.

That changed one day when my wife and I were driving slowly through a mostly desert area of Big Bend Natl. Park in southwest Texas.  When our car turned around the corner of  a small projecting mass of rock that had been hiding part of our view, my wife exclaimed, "That field's growing boulders!"  And how striking indeed was that area of desert beside our car.  It was a flat, tan area of desert, on which it looked as if a giant had been playing with a set of dark-brown marbles ranging from one foot to several feet in diameter.  It was if the surface of the Earth had been turned inside out, with those out-of-place boulders shouting a message about how their lives that had once been underground.  Yet they now stood there before us, unmoving, like a moment frozen in time. A book held open to one page so that we might read it more carefully

Have you ever seen rocks or geological structures that were fascinating to you?

 Chapter IX of Origin of Species [orig. 1859].)

The Mathematics of Miracles

Although most people have never read Walt Whitman's long poem "Song of Myself" in its entirety, many people have heard or read stanzas taken from it.  One such stanza concerns a mouse.  The poem as a whole is Whitman's celebration of all people and all of the natural world as they resonate through Whitman's experience of himself in the world.  The mouse appears in these lines:
"I believe a leaf of grass is no less than the journeywork of the stars,
... And the cow crunching with depressed head surpasses any statue,
And a mouse is miracle enough to stagger sextillions of infidels."

So small, yet so complex.Whitman has, of course, chosen a mouse in part because of its small size -- in contrast to many Christians of his day citing grand events as miracles. But when I first read that line in college, I was able to appreciate his choice of a mouse because I had for awhile had a pet white mouse when I was in high-school.  My mouse was part of a science project.  (The mouse was not going to be harmed in any way -- I was too soft-hearted for that.  I was just going to try to measure its output of carbon dioxide.)

Whitman's statement "a mouse is miracle" evoked my memory of my little white mouse's miraculous features when observed up close:  The slender flexibility of its tail.  The softness of its body despite so much energy.  Its countless white hairs.  Its small round eyes. (Can they really see like mine, although being so tiny?).  Its pointed nose, always seemingly sniffing.  The way it bent its body slightly from side to side as it explored its world.

Poet and church-cleric
John Donne
Whitman's line about the mouse came back to me recently when I read a quotation by a poet who lived two centuries before Whitman.  It was an observation by the poet and church minister John Donne, which struck me as being insightful:  "There is nothing that God hath established in a constant course of Nature, and which is therefore done every day, but would seem a miracle and exercise our admiration, if it were done but once;... The ordinary thing in Nature would be greater miracles than the extraordinary, which we admire most, if they were done but once... and only the daily doing takes off the admiration."  Donne points us toward everyday miracles.

Today, most mainstream Christian, Jewish, and Islamic theologians would join John Donne in cautioning against searching for the miraculous in some rare interruption of the working of natural laws that science has discovered.  As I go about my day, from getting out of bed to going back to sleep at night, everything going on about me can on some level be described as being natural processes.  I might never find God if I expect to find the Divine only in some interruptions of natural laws.

Donne's theological observation, coupled with my memory of Whitman's mentioning a mouse, made me think about the sextillions of little mice throughout the world, sometimes labeled "pests," but each a little miracle in its own right if seen up close.

Is there something in Nature you encounter everyday that you think is marvelous?
