Faulkner's Scientific-Poetic Dynamo

When William Faulkner arrived in Stockholm to receive his Nobel prize for literature he supposedly declared his occupation as “farmer.” (Inge p. 122) Which raises a question—what kind of farmer describes a road “heavy with sixty days of dust, the roadside undergrowth coated with heat-vulcanised dust … [standing] at perpendicular’s absolute in some old dead volcanic water refined to the oxygenless first principle of liquid” (Absalom, Absalom p. 143) ?

A farmer, I guess, who seeds his mind with much reading of literature and modern science and harvests a complex, allusive poetry—in this case informed by engineering, geometry, and paleobiology. The notion of an “oxygenless first principle of liquid” clearly refers to the scientific account of the origin of life, in which all was mineral, dead, and devoid of oxygen until several billion years ago, when the first algae-like organisms commenced photosynthesis, recombining carbon dioxide and water into carbohydrates and oxygen. Though the King James Bible gave Faulkner his title Absalom, Absalom!, he called on the wonder of modern science to re-create the Bible’s sense of primeval magic.

For Faulkner, writing meant curiosity into human motives (Inge ed., p. 166). That is, he made a scientific study of human beings. But what is even more unique about Faulkner is that his poetical effects rely surreptitiously on scientific methods and ideas. Faulkner wrote As I Lay Dying while working nights as a supervisor in the power plant of the University of Mississippi, the school where he’d ten years earlier done a brief stint at college. He told a newspaper in 1932, “I think the hum of the dynamo helped me.” (Inge ed., p. 28) Perhaps it was that “sound of science” that compelled Faulkner’s thoughts in a scientific direction.

Throughout As I Lay Dying, Faulkner seems to scrutinize familiar phenomena so minutely that the familiar becomes strange, as though he were looking into the familiar through a quantum microscope at a weird physics that we’d intuited but never fully understood. Inspired perhaps by modern physics, Faulkner re-sees reality and discovers in it new relationships and underlying properties.

Often he describes relativistic perceptual phenomena wherein motion imparts some new quality to a thing, much as motion influences observations according to both Galilean and Einsteinian relativity. Faulkner even words these descriptions a bit like a physicist witnessing some previously unknown influence in the physical universe.

Take this memorable example where Cash saws planks below his mother’s bedroom window to make her coffin:

He saws again, his elbow flashing slowly, a thin thread of fire running along the edge of the saw, lost and recovered at the top and bottom of each stroke in unbroken elongation, so that the saw appears to be six feet long…. As I Lay Dying, pp. 75-76.

By superimposing the saw’s various positions into one image irrespective of time, the saw elongates in the viewer’s imagination. If you’ve ever done any sawing, you may recognize the weird visual distortion Faulkner describes.

Later, Faulkner establishes the unsettling effect of buzzards by charting the uncanny effect of Galilean relativity on the perception of their motion:

Motionless, the tall buzzards hang in soaring circles, the clouds giving them an illusion of retrograde. p. 95

From Galilean relativity, he proceeds to an observation of a wagon’s motion that sounds blatantly Einsteinian in its linkage of time and space:

We go on, with a motion so soporific, so dreamlike as to be uninferant of progress, as though time and not space were decreasing between us and [Jewel’s horse]. pp. 107-108

The Bundrens’ wagon soon passes a turn-off and the slow movement past the sign and the side road transfers motion to both:

a white signboard with faded lettering: New Hope Church. 3 mi. It wheels up like a motionless hand lifted above the profound desolation of the ocean; beyond it the red road lies like a spoke of which Addie Bundren is the rim. It wheels past, empty, unscarred, the white signboard turns away its fading and tranquil assertion. p. 108

All is still outside the wagon, yet through relativity the moving wagon imparts motion to the motionless signboard so that it turns. The wagon imparts motion to the road so that the road becomes a turning spoke in a wheel and is said to wheel past. Faulkner’s like an experimental physicist researching the relativity and associativity of perceptions.

He observes a similar perceptual relativity in the way that objects derive their shape from their surroundings: “Beyond the unlamped wall,” Darl says, “I can hear the rain shaping the wagon that is ours….” (p. 80) Later, Faulkner describes the shape of the wagon according to the air around it, and suggests an influence that absent things exert over the place they previously occupied, a poetic physics: “[I]t begins to rush away from me and slip down the air like a sled upon invisible snow, smoothly evacuating atmosphere in which the sense of it is still shaped.” (p. 98)

The two types of Faulknerian relativity—of motion and shape—appear together when Darl and Cash and Jewel try to pilot the wagon across the river. Darl looks at his father, sister, and little brother standing on the riverbank and says:

[it is] as though we had reached the place where the motion of the wasted world accelerates just before the final precipice. Yet they appear dwarfed. It is as though the space between us were time: an irrevocable quality. It is as though time, no longer running straight before us in a diminishing line, now runs parallel between us…. [The mules] too are breathing now with a deep groaning sound; looking back once, their gaze sweeps across us with in their eyes a wild, sad, profound and despairing quality as though they had already seen in the thick water the shape of the disaster which they could not speak and we could not see. pp. 146-147

The doomed mules in the river are indisputably real and somehow emblematic of the human condition. As I think of them, I can hear the humming of Faulkner’s dynamo, the scientific-poetic genius apparatus that created them.

Begin the Cosmic Beguine (Big Bang Part I)

Big Bang: The Origin of the UniverseBig Bang: The Origin of the Universe by Simon Singh


It generally takes a child no more than three or four ingenuous questions to reach a humbling horizon beyond which no intellect, whether adult or child or Stephen Hawking, has passed: the question of how the universe began. Whatever we learn about the past, the answer to the next question--what came before that--rears up on the horizon, ever out of reach. I used to lie in bed as a child and imagine infinity until my head hurt.

We do know more than ever before, however, and some of that knowledge has arrived within my own lifetime. Books really do help, especially when written by a science writer par excellence like Simon Singh, who sets out to teach you the subject for real. Singh doesn't water everything down to the point where it makes no sense. He trusts his readers' intelligence and their natural childlike curiosity, and he has the writerly skill to make the real science into a fascinating story--a story which begins not with a bang but a person--Einstein.

Einstein's theory of relativity predicts that matter causes the space of the universe to contract or expand--a dynamic notion of space that cannot be tested by everyday experience, but can be (and has been) tested by data collected from telescopes. Around 1920, Jewish-Russian mathematician Alexander Friedmann applied Einstein's equations to cosmology in order to predict what was happening to the size of the whole universe; he predicted it was expanding. Georges LemaƮtre (a physicist who was also a Catholic priest, pictured next to Einstein in his white collar!) descriptiondid the same and deduced that if the universe has expanded, it must once have been compact. The idea was not that the matter of the universe exploded like shrapnel from a bomb (one reason "Big Bang" is an imperfect name), but rather that the empty space of the universe itself was once compact and ever since has been stretching out like silly putty.

The general theory of relativity is evidently very difficult to translate into plain English, and I don't understand it any further than physicist John Wheeler's famous statement that "Matter tells space how to curve, and curved space tells matter how to move." (It also tells light how to move. I'd like to see if it could get my kids to put their shoes on.) I do know this: whereas matter can't move through space faster than light, space itself can change size faster than the speed of light. It's often said that light from billions of light years away is showing us something billions of years in the past; light from afar is very old; that's putatively because the light has been traveling for billions of years to get to us. I never understood how this could be, since I assumed that distant galaxies must have taken billions of light years to get so far away from our common Big Bang point of origin in the first place. Singh does not address this particular question, but other sources confirm that the universe seems to have expanded much faster than light in the beginning; I presume that's how the infant universe could have blown out to a size billions of light-years across in less than billions of years, and how light from 14 billion light years away therefore could show us baby pictures of the universe. At any rate, Edwin Hubble's observations of the skies, made on freezing nights through a giant telescope in Pasadena, and his analyses of observed Doppler shifts of spectra emitted by familiar elements like helium in distant stars, confirmed that the universe is indeed expanding, with the speed of expansion apparently increasing at farther distances out.

More support for the idea of the Big Bang came from particle physics. Russian refugee George Gamow concluded that the relative abundances of elements in the universe (90% hydrogen, 10% helium, trace amounts of heavier elements, as determined by spectroscopy on the heavens) could best be explained if the universe's matter was once a condensed ball of plasma hotter and more pressurized than that inside stars--he called this universal primordium of subatomic particles ylem. Gamow's young collaborator Ralph Alpher made mathematical models of the primordial universe; they showed that the early universe would have had the right conditions for the right length of time to support "nucleosynthesis" of 10% of the loose protons into helium. Then, with colleague Robert Hermann, Alpher theorized that the early universe should have cooled from plasma to gas 300,000 years after creation, an event called "recombination" (because it was now cool enough for electrons to "recombine" with atomic nuclei instead of flying all over the place? but were they ever combined before that?); they predicted that recombination should have allowed the early universe to radiate light instead of merely scattering it and the light should still be flying through space in every direction and that the expansion of the universe should by now have stretched the wavelength of the extant light of recombination to the point where it would be in the microwave part of the electromagnetic spectrum--the cosmic microwave background radiation (CMB radiation).

At this point the Nobel committee was paying serious attention to the Big Bang theory. In 1965 Arno Penzias and Robert Wilson, who worked for Bell Labs in New Jersey, confirmed the existence of the CMB radiation with a radio telescope and later won the Nobel prize. Finally, George Smoot got NASA to launch a satellite with a radiometer on it so that he could look for miniscule variations in the CMB radiation. These would reflect the existence of condensates of matter in the early universe--the precursors to today's stars and galaxies; NASA launched it in 1989, the radiometer detected it, Smoot too won a Nobel prize for it. I am pretty sure that the variations in the CMB radiation do not explain why half my noodles are hot and half are cold when I reheat a bowl of pasta. Nonetheless, I blame the Big Bang. The end of the story of how we understand the beginning.

There are so many wonderfully human aspects to this history of an idea. The history of astronomy as Singh tells it is a history of passionate, suffering dreamers, of political refugees converging on England and America where they could think in peace. 20th century physics is also a history of the Jews, whose numbers in the Big Bang story far exceed those of helium in the stars (Einstein, Friedmann, Alpher, Hermann, and Penzias are among the Jewish free thinkers who built this progressive theory). The Big Bang is both an elucidation and a revelation of mysteries and cosmic order. Why then, does it hold such potential to make your head hurt and your soul ache with a sense of the empty, senseless, inhumanity of the universe? I feel this anxiety, yet I don't trust it.

More on the Imperfect Science of the Heart

New Introductory Lectures on PsychoanalysisNew Introductory Lectures on Psychoanalysis by Sigmund Freud
My rating: 5 of 5 stars

Every modern, educated person should read this book's predecessor, the (old) Introductory Lectures on Psychoanalysis. For those interested in learning still more about psychoanalysis, the New Introductory Lectures are also vital. The latter work reflects clarifications in Freud's thinking since the original lectures given from 1915 to 1917 at the University of Vienna.

His daughter Anna Freud's book, The Ego and the Mechanisms of Defense is also a very clear, very helpful and common sensical treatment of the subject of psychological defenses--i.e., the varieties of ways the mind lies to itself to protect itself from painful feelings and ideas.

There is at least one chapter in the New Introductory Lectures that is completely bizarre--Freud at his most cavalier and speculative, bordering on ridiculous--and it will do little to dispel the common canard that psychoanalysis is a "pseudo-science." It suffices to say that Freud wasn't perfect. But many great scientists make mistakes or fall prey to ideology; Einstein did (see this article, "The Master's Mistakes" from Discover Magazine); Linus Pauling, one of two people ever to win a Nobel prize in two different areas (Chemistry and Peace), had fairly lunatic ideas about vitamin C; and Isaac Newton wasted a lot of time in foolish speculations about alchemy. But we don't throw out what Einstein and Newton had right and we shouldn't throw out what Freud had right, which is about as revolutionary and beautiful as either of those physicists. Freud's works ought to be read like any other thinker's, not like orthodox readings of a Bible--that is, readers have no reason to try to retrofit reality to correspond with his scriptural errors--and just the same readers have no reason to dump the baby with the bathwater.
