How Natural Is "Natural"?
I
In the more obscure scientific circles which I frequent there is a legend circulating about a late distinguished scientist who, in his declining years, persisted in wearing enormous padded boots much too large for him. He had developed, it seems, what to his fellows was a wholly irrational fear of falling through the interstices of that largely empty molecular space which common men in their folly speak of as the world. A stroll across his living-room floor had become, for him, something as dizzily horrendous as the activities of a window washer on the Empire State Building. Indeed, with equal reason he could have passed a ghostly hand through his own ribs.
The quivering network of his nerves, the awe-inspiring movement of his thought, had become a vague cloud of electrons interspersed with the light-year distances that obtain between us and the farther galaxies. This was the natural world which he had helped to create, and in which, at last, he had found himself a lonely and imprisoned occupant. All around him the ignorant rushed on their way over the illusion of substantial floors, leaping, though they did not see it, from particle to particle, over a bottomless abyss. There was even a question as to the reality of the particles which bore them up. It did not, however, keep insubstantial newspapers from being sold, or insubstantial love from being made.
Not long ago I became aware of another world perhaps equally natural and real, which man is beginning to forget. My thinking began in New England under a boat dock. The lake I speak of has been pre-empted and civilized by man. All day long in the vacation season high-speed motorboats, driven with the reckless abandon common to the young Apollos of our society, speed back and forth, carrying loads of equally attractive girls. The shores echo to the roar of powerful motors and the delighted screams of young Americans with uncounted horsepower surging under their hands. In truth, as I sat there under the boat dock, I had some desire to swim or to canoe in the older ways of the great forest which once lay about this region. Either notion would have been folly. I would have been gaily chopped to ribbons by teen-age youngsters whose eyes were always immutably fixed on the far horizons of space or upon the dials which indicated the speed of their passing. There was another world, I was to discover, along the lake shallows and under the boat dock, where the motors could not come.
As I sat there one sunny morning when the water was peculiarly translucent, I saw a dark shadow moving swiftly over the bottom. It was the first sign of life I had seen in this lake, whose shores seemed to yield little but washed-in beer cans. By and by the gliding shadow ceased to scurry from stone to stone over the bottom. Unexpectedly, it headed almost directly for me. A furry nose with gray whiskers broke the surface. Below the whiskers green water foliage trailed out in an inverted V as long as his body. A muskrat still lived in the lake. He was bringing in his breakfast.
I sat very still in the strips of sunlight under the pier. To my surprise the muskrat came almost to my feet with his little breakfast of greens. He was young, and it rapidly became obvious to me that he was laboring under an illusion of his own, and that he thought animals and men were still living in the Garden of Eden. He gave me a friendly glance from time to time as he nibbled his greens. Once, even, he went out into the lake again and returned to my feet with more greens. He had not, it seemed, heard very much about men. I shuddered. Only the evening before I had heard a man describe with triumphant enthusiasm how he had killed a rat in the garden because the creature had dared to nibble his petunias. He had even showed me the murder weapon, a sharp-edged brick.
On this pleasant shore a war existed and would go on until nothing remained but man. Yet this creature with the gray, appealing face wanted very little: a strip of shore to coast up and down, sunlight and moonlight, some weeds from the deep water. He was an edge-of-the- world dweller, caught between a vanishing forest and a deep lake pre-empted by unpredictable machines full of chopping blades. He eyed me near-sightedly, a green leaf poised in his mouth. Plainly he had come with some poorly instructed memory about the lion and the lamb.
"You had better run away now," I said softly, making no movement in the shafts of light. "You are in the wrong universe and must not make this mistake again. I am really a very terrible and cunning beast. I can throw stones." With this I dropped a little pebble at his feet.
He looked at me half blindly, with eyes much better adjusted to the wavering shadows of his lake bottom than to sight in the open air. He made almost as if to take the pebble up into his forepaws. Then a thought seemed to cross his mind -- a thought perhaps telepathically received, as Freud once hinted, in the dark world below and before man, a whisper of ancient disaster heard in the depths of a burrow. Perhaps after all this was not Eden. His nose twitched carefully; he edged toward the water.
As he vanished in an oncoming wave, there went with him a natural world, distinct from the world of girls and motorboats, distinct from the world of the professor holding to reality by some great snowshoe effort in his study. My muskrat's shoreline universe was edged with the dark wall of hills on one side and the waspish drone of motors farther out, but it was a world of sunlight he had taken down into the water weeds. It hovered there, waiting for my disappearance. I walked away, obscurely pleased that darkness had not gained on life by any act of mine. In so many worlds, I thought, how natural is "natural" -- and is there anything we can call a natural world at all?
II
Nature, contended John Donne in the seventeenth century, is the common law by which God governs us. Donne was already aware of the new science and impressed by glimpses of those vast abstractions which man was beginning to build across the gulfs of his ignorance. Donne makes, however, a reservation which rings strangely in the modern ear. If nature is the common law, he said, then Miracle is God's Prerogative.
By the nineteenth century, this spider web of common law had been flung across the deeps of space and time. "In astronomy," meditated Emerson, "vast distance, but we never go into a foreign system. In geology, vast duration, but we are never strangers. Our meta physic should be able to follow the flying force through all its transformations."
Now admittedly there is a way in which all these worlds are real and sufficiently natural. We can say, if we like, that the muskrat's world is naive and limited, a fraction, a bare fraction, of the world of life: a view from a little pile of wet stones on a nameless shore. The view of the motor speedsters in essence is similar and no less naive. All would give way to the priority of that desperate professor, striving like a tired swimmer to hold himself aloft against the soft and fluid nothingness beneath his feet. In terms of the modern temper, the physicist has penetrated the deepest into life. He has come to that place of whirling sparks which are themselves phantoms. He is close upon the void where science ends and the manifestation of Cod's Prerogative begins. "He can be no creature," argued Donne, "who is present at the first creation."
Yet there is a way in which the intelligence of man in this era of science and the machine can be viewed as having taken the wrong turning. There is a dislocation of our vision which is, perhaps, the product of the kind of creatures we are, or at least conceive ourselves to be. Man, as a two-handed manipulator of the world about him, has projected himself outward upon his surroundings in a way impossible to other creatures. He has done this since the first half-human man-ape hefted a stone in his hand. He has always sought mastery over the materials of his environment, and in our day he has pierced so deeply through the screen of appearances that the age-old distinctions between matter and energy have been dimmed to the point of disappearance. The creations of his clever intellect ride in the skies and the sea's depths; he has hurled a great fragment of metal at the moon, which he once feared. He holds the heat of suns within his hands and threatens with it both the lives and the happiness of his unborn descendants.
Man, in the words of one astute biologist, is "caught in a physiological trap and faced with the problem of escaping from his own ingenuity." Pascal, with intuitive sensitivity, saw this at the very dawn of the modern era in science. "There is nothing which we cannot make natural," he wrote, and then, prophetically, comes the full weight of his judgment upon man: "there is nothing natural which we do not destroy." Homo faber, the toolmaker, is not enough. There must be another road and another kind of man lurking in the mind of this odd creature, but whether the attraction of that path is as strong as the age-old primate addiction to taking things apart remains to be seen.
We who are engaged in the life of thought are likely to assume that the key to an understanding of the world is knowledge, both of the past and of the future -- that if we had that knowledge we would also have wisdom. It is not my intention here to decry learning, but only to say that we must come to understand that learning is endless and that nowhere does it lead us behind the existent world. It may reduce the prejudices of ignorance, set our bones, build our cities. In itself it will never make us ethical men. Yet because ours, we conceive, is an age of progress, and because we know more about time and history than any men before us, we fallaciously equate ethical advance with scientific progress in a point-to-point relationship. Thus as society improves physically, we assume the improvement of the individual and are all the more horrified at those mass movements of terror which have so typified the first half of the twentieth century.
On the morning of which I want to speak, I was surfeited with the smell of mortality and tired of the years I had spent in archaeological dustbins. I rode out of a camp and across a mountain. I would never have believed, before it happened, that one could ride into the past on horseback. It is true I rode with a purpose, but that purpose was to settle an argument within myself.
It was time, I thought, to face up to what was in my mind -- to the dust and the broken teeth and the spilled chemicals of life seeping away into the sand. It was time I admitted that life was of the earth, earthy, and could be turned into a piece of wretched tar. It was time I consented to the proposition that man had as little to do with his fate as a seed blown against a grating. It was time I looked upon the world without spectacles and saw love and pride and beauty dissolve into effervescing juices. I could be an empiricist with the best of them. I would be deceived by no more music. I had entered a black cloud of merciless thought, but the horse, as it chanced, worked his own way over that mountain.
I could hear the sudden ring of his hooves as we came cautiously treading over a tilted table of granite, past the winds that blow on the high places of the world. There were stones there so polished that they shone from the long ages that the storms had rushed across them. We crossed the divide then, picking our way in places scoured by ancient ice action, through boulder fields where nothing moved, and yet where one could feel time like an enemy hidden behind each stone.
If there was life on those heights, it was the thin life of mountain spiders who caught nothing in their webs, or of small gray birds that slipped soundlessly among the stones. The wind in the pass caught me head on and blew whatever thoughts I had into a raveling stream behind me, until they were all gone and there was only myself and the horse, moving in an eternal dangerous present, free of the encumbrances of the past.
We crossed a wind that smelled of ice from still higher snowfields, we cantered with a breeze that came from somewhere among cedars, we passed a gust like Hell's breath that had risen straight up from the desert floor. They were winds and they did not stay with us. Presently we descended out of their domain, and it was curious to see, as we dropped farther through gloomy woods and canyons, how the cleansed and scoured mind I had brought over the mountain began, like the water in those rumbling gorges, to talk in a variety of voices, to debate, to argue, to push at stones or curve subtly around obstacles. Sometimes I wonder whether we are only endlessly repeating in our heads an argument that is going on in the world's foundations among crashing stones and recalcitrant roots.
"Fall, fall, fall," cried the roaring water and the grinding pebbles in the torrent. "Let go, come with us, come home to the place without light." But the roots clung and climbed and the trees pushed up, impeding the water, and forests filled even the wind with their sighing and grasped after the sun. It is so in the mind. One can hear the rattle of falling stones in the night, and the thoughts like trees holding their place. Sometimes one can shut the noise away by turning over on the other ear, sometimes the sounds are as dreadful as a storm in the mountains, and one lies awake, holding, like the roots that wait for daylight. It was after such a night that I came over the mountain, but it was the descent on the other side that suddenly struck me as a journey into the aeons of the past.
I came down across stones dotted with pink and gray lichens -- a barren land dreaming life's last dreams in the thin air of a cold and future world.
I passed a meadow and a meadow mouse in a little shower of petals struck from mountain flowers. I dismissed it -- it was almost my own time -- a pleasant golden hour in the age of mammals, lost before the human coming. I rode heavily toward an old age far backward in the reptilian dark.
I was below timber line and sinking deeper and deeper into the pine woods, whose fallen needles lay thick and springy over the ungrassed slopes. The brown needles and the fallen cones, the stiff, endless green forests, were a mark that placed me in the Age of Dinosaurs. I moved in silence now, waiting a sign. I saw it finally, a green lizard on a stone. We were far back, far back. He bobbed his head uncertainly at me, and I reined in with the nostalgic intent, for a moment, to call him father, but I saw soon enough that I was a ghost who troubled him and that he would wish me, though he had not the voice to speak, to ride on. A man who comes down the road of time should not expect to converse -- even with his own kin. I made a brief, uncertain sign of recognition, to which he did not respond, and passed by. Things grew more lonely. I was coming out upon the barren ridges of an old sea beach that rose along the desert floor. Life was small and grubby now. The hot, warning scarlet of peculiar desert ants occasionally flashed among the stones. I had lost all trace of myself and thought regretfully of the lizard who might have directed me.
A turned-up stone yielded only a scorpion who curled his tail in a kind of evil malice. I surveyed him reproachfully. He was old enough to know the secret of my origin, but once more an ancient, bitter animus drawn from that poisoned soil possessed him and he raised his tail. I turned away. An enormous emptiness by degrees possessed me. I was back almost, in a different way, to the thin air over the mountain, to the end of all things in the cold starlight of space.
I passed some indefinable bones and shells in the salt-crusted wall of a dry arroyo. As I reined up, only sand dunes rose like waves before me and if life was there it was no longer visible. It was like coming down to the end -- to the place of fires where we began. I turned about then and let my gaze go up, tier after tier, height after height, from crawling desert bush to towering pine on the great slopes far above me.
In the same way animal life had gone up that road from these dry, envenomed things to the deer nuzzling a fawn in the meadows far above. I had come down the whole way into a place where one could lift sand and ask in a hollow, dust-shrouded whisper, "Life, what is it? Why am I here? Why am I here?"
And my mind went up that figurative ladder of the ages, bone by bone, skull by skull, seeking an answer. There was none, except that in all that downrush of wild energy that I had passed in the canyons there was this other strange organized stream that marched upward, gaining a foothold here, tossing there a pine cone a little farther upward into a crevice in the rock.
And again one asked, not of the past this time, but of the future, there where the winds howled through open space and the last lichens clung to the naked rock, "Why did we live?" There was no answer I could hear. The living river flowed out of nowhere into nothing. No one knew its source or its departing. It was an apparition. If one did not see it there was no way to prove that it was real.
No way, that is, except within the mind itself. And the mind, in some strange manner so involved with time, moving against the cutting edge of it like the wind I had faced on the mountain, has yet its own small skull-borne image of eternity. It is not alone that I can reach out and receive within my head a handsbreadth replica of the far fields of the universe. It is not because I can touch a trilobite and know the fall of light in ages before my birth. Rather, it lies in the fact that the human mind can transcend time, even though trapped, to all appearances, within that medium. As from some remote place, I see myself as child and young man, watch with a certain dispassionate objectivity the violence and tears of a remote youth who was once I, shaping his character, for good or ill, toward the creature he is today. Shrinking, I see him teeter at the edge of abysses he never saw. With pain I acknowledge acts undone that might have saved and led him into some serene and noble pathway. I move about him like a ghost, that vanished youth. I exhort, I plead. He does not hear me. Indeed, he too is already a ghost. He has become me. I am what I am. Yet the point is, we are not wholly given over to time -- if we were, such acts, such leaps through that gray medium, would be impossible. Perhaps God himself may rove in similar pain up the dark roads of his universe. Only how would it be, I wonder, to contain at once both the beginning and the end, and to hear, in helplessness perhaps, the fall of worlds in the night?
This is what the mind of man is just beginning to achieve-a little microcosm, a replica of whatever it is that, from some unimaginable "outside," contains the universe and all the fractured bits of seeing which the world's creatures see. It is not necessary to ride over a mountain range to experience historical infinity. It can descend upon one in the lecture room.
I find it is really in daylight that the sensation I am about to describe is apt to come most clearly upon me, and for some reason I associate it extensively with crowds. It is not, you understand, an hallucination. It is a reality. It is, I can only say with difficulty, a chink torn in a dimension life was never intended to look through. It connotes a sense beyond the eye, though the twenty years' impressions are visual. Man, it is said, is a time-binding animal, but he was never intended for this. Here is the way it comes.
I mount the lecturer's rostrum to address a class. Like any work-worn professor fond of his subject, I fumble among my skulls and papers, shuffle to the blackboard and back again, begin the patient translation of three billion years of time into chalk scrawls and uncertain words ventured timidly to a sea of young, impatient faces. Time does not frighten them, I think enviously. They have, most of them, never lain awake and grasped the sides of a cot, staring upward into the dark while the slow clock strokes begin.
"Doctor." A voice diverts me. I stare out nearsightedly over the class. A hand from the back row gesticulates. "Doctor, do you believe there is a direction to evolution? Do you believe, Doctor ... Doctor, do you believe? ... " Instead of the words, I hear a faint piping, and see an eager scholar's face squeezed and dissolving on the body of a chest-thumping ape. "Doctor, is there a direction?"
I see it then -- the trunk that stretches monstrously behind him. It winds out of the door, down dark and obscure corridors to the cellar, and vanishes into the floor. It writhes, it crawls, it barks and snuffles and roars, and the odor of the swamp exhales from it. That pale young scholar's face is the last bloom on a curious animal extrusion through time. And who among us, under the cold persuasion of the archaeological eye, can perceive which of his many shapes is real, or if, perhaps, the entire shape in time is not a greater and more curious animal than its single appearance?
I too am aware of the trunk that stretches loathsomely back of me along the floor. I too am a many-visaged thing that has climbed upward out of the dark of endless leaf falls, and has slunk, furred, through the glitter of blue glacial nights. I, the professor, trembling absurdly on the platform with my book and spectacles, am the single philosophical animal. I am the unfolding worm, and mud fish, the weird tree of Igdrasil shaping itself endlessly out of darkness toward the light.
I have said this is not an illusion. It is when one sees in this manner, or a sense of strangeness halts one on a busy street to verify the appearance of one's fellows, that one knows a terrible new sense has opened a faint crack into the Absolute. It is in this way alone that one comes to grips with a great mystery, that life and time bear some curious relationship to each other that is not shared by inanimate things.
It is in the brain that this world opens. To our descendants it may become a commonplace, but me, and others like me, it has made a castaway. I have no refuge in time, as others do who troop homeward at nightfall. As a result, I am one of those who linger furtively over coffee in the kitchen at bedtime or haunt the all-night restaurants. Nevertheless, I shall say without regret: there are hazards in all professions.
III
It may seem at this point that I have gone considerably round about in my examination of the natural world. I have done so in the attempt to indicate that the spider web of law which has been flung, as Emerson indicated, across the deeps of time and space and between each member of the living world has brought us some quite remarkable, but at the same time disquieting, knowledge. In rapid summary, man has passed from a natural world of appearances invisibly controlled by the caprice of spirits to an astronomical universe visualized by Newton, through the law of gravitation, as operating with the regularity of a clock.
Newton, who remained devout, assumed that Cod, at the time of the creation of the solar system, had set everything to operating in its proper orbit. He recognized, however, certain irregularities of planetary movement which, in time, would lead to a disruption of his perfect astronomical machine. It was here, as a seventeenth- century scholar, that he felt no objection to the notion that Cod interfered at periodic intervals to correct the deviations of the machine.
A century later Laplace had succeeded in dispensing with this last vestige of divine intervention. Hutton had similarly dealt with supernaturalism in earth-building, and Darwin, in the nineteenth century, had gone far toward producing a similar mechanistic explanation of life. The machine that began in the heavens had finally been installed in the human heart and brain. "We can make everything natural," Pascal had truly said, and surely the more naive forms of worship of the unseen are vanishing.
Yet strangely, with the discovery of evolutionary, as opposed to purely durational, time, there emerges into this safe-and-sane mechanical universe something quite unanticipated by the eighteenth-century rationalists -- a kind of emergent, if not miraculous, novelty.
I know that the word "miraculous" is regarded dubiously in scientific circles because of past quarrels with theologians. The word has been defined, however, as an event transcending the known laws of nature. Since, as we have seen, the laws of nature have a way of being altered from one generation of scientists to the next, a little taste for the miraculous in this broad sense will do us no harm. We forget that nature itself is one vast miracle transcending the reality of night and nothingness. We forget that each one of us in his personal life repeats that miracle.
Whatever may be the power behind those dancing motes to which the physicist has penetrated, it makes the light of the muskrat's world as it makes the world of the great poet. It makes, in fact, all of the innumerable and private worlds which exist in the heads of men. There is a sense in which we can say that the planet, with its strange freight of life, is always just passing from the unnatural to the natural, from that Unseen which man has always reverenced to the small reality of the day. If all life were to be swept from the world, leaving only its chemical constituents, no visitor from another star would be able to establish the reality of such a phantom. The dust would lie without visible protest, as it does now in the moon's airless craters, or in the road before our door.
Yet this is the same dust which, dead, quiescent, and unmoving, when taken up in the process known as life, hears music and responds to it, weeps bitterly over time and loss, or is oppressed by the looming future that is, on any materialist terms, the veriest shadow of nothing. How natural was man, we may ask, until he came? What forces dictated that a walking ape should watch the red shift of light beyond the island universes or listen by carefully devised antennae to the pulse of unseen stars? Who, whimsically, conceived that the plot of the world should begin in a mud puddle and end -- where, and with whom? Men argue learnedly over whether life is chemical chance or antichance, but they seem to forget that the life in chemicals may be the greatest chance of all, the most mysterious and unexplainable property in matter.
"The special value of science," a perceptive philosopher once wrote, "lies not in what it makes of the world, but in what it makes of the knower." Some years ago, while camping in a vast eroded area in the West, I came upon one of those unlikely sights which illuminate such truths.
I suppose that nothing living had moved among those great stones for centuries. They lay toppled against each other like fallen dolmens. The huge stones were beasts, I used to think, of a kind that man ordinarily lived too fast to understand. They seemed inanimate because the tempo of the life in them was slow. They lived ages in one place and moved only when man was not looking. Sometimes at night I would hear a low rumble as one drew itself into a new position and subsided again. Sometimes I found their tracks ground deeply into the hillsides.
It was with considerable surprise that while traversing this barren valley I came, one afternoon, upon what I can only describe as a very remarkable sight. Some distance away, so far that for a little space I could make nothing of the spectacle, my eyes were attracted by a dun-colored object about the size of a football, which periodically bounded up from the desert floor. Wonderingly, I drew closer and observed that something ropelike which glittered in the sun appeared to be dangling from the ball-shaped object. Whatever the object was, it appeared to be bouncing faster and more desperately as I approached. My surroundings were such that this hysterical dance of what at first glance appeared to be a common stone was quite unnerving, as though suddenly all the natural objects in the valley were about to break into a jig. Going closer, I penetrated the mystery.
The sun was sparkling on the scales of a huge blacksnake which was partially looped about the body of a hen pheasant. Desperately the bird tried to rise, and just as desperately the big snake coiled and clung, though each time the bird, falling several feet, was pounding the snake's body in the gravel. I gazed at the scene in astonishment. Here in this silent waste, like an emanation from nowhere, two bitter and desperate vapors, two little whirlwinds of contending energy, were beating each other to death because their plans -- something, I suspected, about whether a clutch of eggs was to turn into a thing with wings or scales -- this problem, I say, of the onrushing nonexistent future, had catapulted serpent against bird.
The bird was too big for the snake to have had it in mind as prey. Most probably, he had been intent on stealing the pheasant's eggs and had been set upon and pecked. Somehow in the ensuing scuffle he had flung a loop over the bird's back and partially blocked her wings. She could not take off, and the snake would not let go. The snake was taking a heavy battering among the stones, but the high-speed metabolism and tremendous flight exertion of the mother bird were rapidly exhausting her. I stood a moment and saw the bloodshot glaze deepen in her eyes. I suppose I could have waited there to see what would happen when she could not fly; I suppose it might have been worth scientifically recording. But I could not stand that ceaseless, bloody pounding in the gravel. I thought of the eggs somewhere about, and whether they were to elongate and writhe into an armor of scales or eventually to go whistling into the wind with their wild mother.
So I, the mammal, in my way supple, and less bound by instinct, arbitrated the matter. I unwound the serpent from the bird and let him hiss and wrap his battered coils around my arm. The bird, her wings flung out, rocked on her legs and gasped repeatedly. I moved away in order not to drive her farther from her nest. Thus the serpent and I, two terrible and feared beings, passed quickly out of view.
Over the next ridge, where he could do no more damage, I let the snake, whose anger had subsided, slowly uncoil and slither from my arm. He flowed away into a little patch of bunch grass -- aloof, forgetting, unaware of the journey he had made upon my wrist, which throbbed from his expert constriction. The bird had contended for birds against the oncoming future; the serpent writhing into the bunch grass had contended just as desperately for serpents. And I, the apparition in that valley -- for what had I contended? -- I who contained the serpent and the bird and who read the past long written in their bodies.
Slowly, as I sauntered dwarfed among overhanging pinnacles, as the great slabs which were the visible remnants of past ages laid their enormous shadows rhythmically as life and death across my face, the answer came to me. Man could contain more than himself. Among these many appearances that flew, or swam in the waters, or wavered momentarily into being, man alone possessed that unique ability.
The Renaissance thinkers were right when they said that man, the Microcosm, contains the Macrocosm. I had touched the lives of creatures other than myself and had seen their shapes waver and blow like smoke through the corridors of time. I had watched, with sudden concentrated attention, myself, this brain, unrolling from the seed like a genie from a bottle, and casting my eyes forward, I had seen it vanish again into the formless alchemies of the earth.
For what then had I contended, weighing the serpent with the bird in that wild valley? I had struggled, I am now convinced, for a greater, more comprehensive version of myself.
IV
I am a man who has spent a great deal of his life on his knees, though not in prayer. I do not say this last pridefully, but with the feeling that the posture, if not the thought behind it, may have had some final salutary effect. I am a naturalist and a fossil hunter, and I have crawled most of the way through life. I have crawled downward into holes without a bottom, and upward, wedged into crevices where the wind and the birds scream at you until the sound of a falling pebble is enough to make the sick heart lurch. In man, I know now, there is no such thing as wisdom. I have learned this with my face against the ground. It is a very difficult thing for a man to grasp today, because of his power; yet in his brain there is really only a sort of universal marsh, spotted at intervals by quaking green islands representing the elusive stability of modern science -- islands frequently gone as soon as glimpsed.
It is our custom to deny this; we are men of precision, measurement and logic; we abhor the unexplainable and reject it. This, too, is a green island. We wish our lives to be one continuous growth in knowledge; indeed, we expect them to be. Yet well over a hundred years ago Kierkegaard observed that maturity consists in the discovery that "there comes a critical moment where everything is reversed, after which the point becomes to understand more and more that there is something which cannot be understood."
When I separated the serpent from the bird and released them in that wild upland, it was not for knowledge; not for anything I had learned in science. Instead, I contained, to put it simply, the serpent and the bird. I would always contain them. I was no longer one of the contending vapors; I had embraced them in my own substance and, in some insubstantial way, reconciled them, as I had sought reconciliation with the muskrat on the shore. I had transcended feather and scale and gone beyond them into another sphere of reality. I was trying to give birth to a different self whose only expression lies again in the deeply religious words of Pascal, "You would not seek me had you not found me."
I had not known what I sought, but I was aware at last that something had found me. I no longer believed that nature was either natural or unnatural, only that nature now appears natural to man. But the nature that appears natural to man is another version of the muskrat's world under the boat dock, or the elusive sparks over which the physicist made his trembling passage. They were appearances, specialized insights, but unreal because in the constantly onrushing future they were swept away.
What had become of the natural world of that gorilla-headed little ape from which we sprang -- that dim African corner with its chewed fish bones and giant Ice Age pigs? It was gone more utterly than my muskrat's tiny domain, yet it had given birth to an unimaginable thing -- ourselves -- something overreaching the observable laws of that far epoch. Man since the beginning seems to be awaiting an event the nature of which he does not know. "With reference to the near past," Thoreau once shrewdly commented, "we all occupy the region of common sense, but in the prospect of the future we are, by instinct, transcendentalists." This is the way of the man who makes nature "natural." He stands at the point where the miraculous comes into being, and after the event he calls it "natural." The imagination of man, in its highest manifestations, stands close to the doorway of the infinite, to the world beyond the nature that we know. Perhaps, after all, in this respect man constitutes the exertion of that act which Donne three centuries ago called God's Prerogative.
Man's quest for certainty is, in the last analysis, a quest for meaning. But the meaning lies buried within himself rather than in the void he has vainly searched for portents since antiquity. Perhaps the first act in its unfolding was taken by a raw beast with a fearsome head who dreamed some difficult and unimaginable thing denied his fellows. Perhaps the Rashes of beauty and insight which trouble us so deeply are no less prophetic of what the race might achieve. All that prevents us is doubt -- the power to make everything natural without the accompanying gift to see, beyond the natural, to that inexpressible realm in which the words "natural" and "supernatural" cease to have meaning.
Man, at last, is face to face with himself in natural guise. "What we make natural, we destroy," said Pascal. He knew, with superlative insight, man's complete necessity to transcend the worldly image that this word connotes. It is not the outward powers of man the toolmaker that threaten us. It is a growing danger which has already afflicted vast areas of the world -- the danger that we have created an unbearable last idol for our worship. That idol, that uncreate and ruined visage which confronts us daily, is no less than man made natural. Beyond this replica of ourselves, this countenance already grown so distantly inhuman that it terrifies us, still beckons the lonely figure of man's dreams. It is a nature, not of this age, but of the becoming -- the light once glimpsed by a creature just over the threshold from a beast, a despairing cry from the dark shadow of a cross on Golgotha long ago.
Man is not totally compounded of the nature we profess to understand. Man is always partly of the future, and the future he possesses a power to shape. "Natural" is a magician's word -- and like all such entities, it should be used sparingly lest there arise from it, as now, some unglimpsed, unintended world, some monstrous caricature called into being by the indiscreet articulation of worn syllables. Perhaps, if we are wise, we will prefer to stand like those forgotten humble creatures who poured little gifts of flints into a grave. Perhaps there may come to us then, in some such moment, a ghostly sense that an invisible doorway has been opened -- a doorway which, widening out, will take man beyond the nature that he knows.
