Being at Home in the World/Universe

The French philosopher Maurice Merleau-Ponty provided an introduction to the problem of being at home when he wrote:

“The world is not what I think, but what I live through. I am open to the world, I have no doubt that I am in communication with it, but I do not possess it; it is inexhaustible. ‘There is a world’, or rather: “There is the world’; I can never completely account for this ever-reiterated assertion in my life.”

Joseph J. Kockelmans (Editor), Phenomenology: The Philosophy of Edmund Husserl and Its Interpretation, Anchor Books Edition, 1967, page 369.

Remy C. Kwant, in his essay “Merleau-Ponty and Phenomenology”, commented:

For, according to him, the original lies buried in a dimension of darkness in such a way that it cannot be brought to light. Our existence is interwoven with the world, is a dialogue with the world. This dialogue reaches its most profound point there where the first and most original meaning arises, a meaning that is pre-conscious and pre-personal. Whatever is in our consciousness, whatever comes to light, becomes lucid, originates also in this darkness. As we have seen, man is able to obtain a measure of knowledge regarding this dark depth. He is able to divine something about the mysterious dialogue between the body-subject and the world. However, according to Merleau-Ponty, an absolute illumination of the phenomenal field is in principle impossible. All man can do is to erect some pointers in a darkness which resists full illumination.

Joseph J. Kockelmans (Editor), Phenomenology: The Philosophy of Edmund Husserl and Its Interpretation, Anchor Books Edition, 1967, page 390-391.

We sense that the interaction between ourselves and the world at every level may not be explainable. Therefore, we seek emotional or psychological shelter. The three levels of shelter are:

  1. hearth and home
  2. a sense of belonging
  3. gods

Think of the song, “A House Is Not a Home”, sung by Dionne Warwick. “A chair is still a chair / Even though there’s no one sitting there … But a room is not a house
/ And a house is not a home” depicts the human longing for shelter via hearth and home. The French philosopher Bruno Latour referred to this as a “parliament of things.”

Consider “Gimme Shelter” by The Rolling Stones, as well as the novel (and later film) The Sheltering Sky by Paul Bowles. Both of these cover the deep issue of shelter.

Heidegger’s essay “Building Dwelling Thinking” (German: Bauen Wohnen Denken) states:

In what follows we shall try to think about dwelling and building. This thinking about building does not presume to discover architectural ideas, let alone to give rules for building. This venture in thought does not view building as an art or as a technique of construction; rather it traces building back into that domain to which everything that is belongs. We ask:

  1.   What is it to dwell?
  2.   How does building belong to dwelling?
I

We attain to dwelling, so it seems, only by means of building. The latter, building, has the former, dwelling, as its goal. Still, not every building is a dwelling. Bridges and hangars, stadiums and power stations are buildings but not dwellings; railway stations and highways, dams and market halls are built, but they are not dwelling places. Even so, these buildings are in the domain of our dwelling. That domain extends over these buildings and yet is not limited to the dwelling place. The truck driver is at home on the highway, but he does not have his shelter there; the working woman is at home in the spinning mill, but does not have her dwelling place there; the chief engineer is at home in the power station, but he does not dwell there. These buildings house man. He inhabits them and yet does not dwell in them, when to dwell means merely that we take shelter in them. In today’s housing shortage even this much is reassuring and to the good; residential buildings do indeed provide shelter; today’s houses may even be well planned, easy to keep, attractively cheap, open to air, light, and sun, but—do the houses in themselves hold any guarantee that dwelling occurs in them? Yet those buildings that are not dwelling places remain in turn determined by dwelling insofar as they serve man’s dwelling. Thus dwelling would in any case be the end that presides over all building. Dwelling and building are related as end and means. However, as long as this is all we have in mind, we take dwelling and building as two separate activities, an idea that has something correct in it. Yet at the same time by the means-end schema we block our view of the essential relations. For building is not merely a means and a way toward dwelling—to build is in itself already to dwell. Who tells us this? Who gives us a standard at all by which we can take the measure of the nature of dwelling and building?

Martin Heidegger, Poetry, Language, Thought, (translated by Albert Hofstadter), Harper & Row, 1975, pages 145-146.

Stuart Kauffman comes at this from a different angle:

Who are we? Where did we come from? Why are we here? Did Neanderthal, Homo habilis, or Homo erectus ask? Around which fire in the past 3 million years of hominid evolution did these questions first arise? Who knows.

Somewhere along our path, paradise has been lost, lost to the Western mind, and in the spreading world civilization, lost to our collective mind. John Milton must have been the last superb poet of Western civilization who could have sought to justify the ways of God to man in those early years foreshadowing the modern era. Paradise has been lost, not to sin, but to science. Once, a scant few centuries ago, we of the West believed ourselves the chosen of God, made in his image, keeping his word in a creation wrought by his love for us. Now, only 400 years later, we find ourselves on a tiny planet, on the edge of a humdrum galaxy among billions like it scattered across vast megaparsecs, around the curvature of space-time back to the Big Bang. We are but accidents, we’re told. Purpose and value are ours alone to make. Without Satan and God, the universe now appears the neutral home of matter, dark and light, and is utterly indifferent. We bustle, but are no longer at home in the ancient sense.

Stuart Kauffman, At Home in the Universe: The Search for the Laws of Self-Organization and Complexity, Oxford University Press, 1995, page 4.

Kauffman comes to grips with this problem with the final line above. He continues:


In this new view of life, organisms are not merely tinkered-together contraptions, bricolage, in Jacob’s phrase. Evolution is not merely “chance caught on the wing,” in Monod’s evocative image. The history of life captures the natural order, on which selection is privileged to act. If this idea is true, many features of organisms are not merely historical accidents, but also reflections of the profound order that evolution has further molded. If true, we are at home in the universe in ways not imagined since Darwin stood natural theology on is head with his blind watchmaker.

Stuart Kauffman, At Home in the Universe: The Search for the Laws of Self-Organization and Complexity, Oxford University Press, 1995, pages 25-26.

Kauffman wants to complete the Darwinian revolution by adding self-organization and complexity to natural selection. In his vision, this will begin to produce a holistic picture of who we are. This will perhaps allow us to feel “We are all at home in the universe, poised to sanctify by our best, brief, only stay.” [page 30.]

Zooming out from this, we can see a meta-intelligent sense in which science believes it can convert mysteries into problems using math. In contrast to this, philosophers believe the opposite, that the problems are becoming more mysterious.

Price Revolutions and Their Historical Impact

In 1996, leading economic historian, David Hackett Fischer, published The Great Wave: Price Revolutions and the Rhythm of History. If you ponder the subtitle, you may grasp the work’s ambition.

Nobel Prize-winning economist Paul Krugman has been arguing with Fischer for many years that, in making the transition from business to historical cycles, Fischer’s position is problematic.

There are, of course, detailed histories of prices, such as Thomas Tooke’s A History of Prices and of the State of the Circulation during the Years 1793–1856 (6 volumes, 1838–1857).

In the first four volumes he treats (a) of the prices of corn, and the circumstances affecting prices; (b) the prices of produce other than corn; and (c) the state of the circulation. The two final volumes, written with William Newmarch, deal with railways, free trade, banking in Europe and the effects of new discoveries of gold.

Wikipedia (links added)

Tooke-type price histories are one thing, but what about Fischer’s price revolutions? Max Weber (who predates Fischer by almost a century) seems to endorse this concept. In Weber’s General Economic History (German: Wirtschaftsgeschichte), he writes:

The great price revolution of the 16th and 17th centuries provided a powerful lever for the specifically capitalistic tendencies of seeking profit through cheapening production and lowering the price. This revolution is rightly ascribed to the continuous inflow of precious metals, in consequence of the great overseas discoveries. It lasted from the thirties of the 16th century down to the time of the Thirty Years’ War, but affected different branches of economic life in quite different ways. In the case of agricultural products an almost universal rise in price set in, making it possible for them to go over to production for the market. It was quite otherwise with the course of prices for industrial products. By and large these remained stable or rose in price relatively little, thus really falling, in comparison with the agricultural products. This relative decline was made possible only through a shift in technology and economics, and exerted a pressure in the direction of increasing profit by repeated cheapening of production. Thus the development did not follow the order that capitalism set in first and the decline in prices followed, but the reverse; first the prices fell relatively and then came capitalism.

Max Weber, General Economic History, Collier Books (3rd printing), 1966, pages 230-231.

Notice the last sentence above, Weber explicitly describes price revolutions exactly as Fischer argues.

In the history books we read, the emphasis is always on colorful personalities, inventions and other more theatrical events. This obviously omits the idea of phenomena like price revolutions. We cannot explain history merely by these personalities; we need to zoom out and view the larger picture.

Education and the Long-Term: Automation As Example

The American Revolution: Pages From a Negro Worker’s Notebook

Chapter 2: The Challenge of Automation

“Since 1955 and the advent of automation, overtime has been detrimental to the workers. Again and again workers have been faced with the decision to work overtime or not to work overtime, and the decision has usually been: ‘To hell with those out of work. Let’s get the dollar while the dollar is gettable.’ The amazing thing is that this has nothing to do with the backwardness of these workers. Not only can they run production and think for themselves, but they sense and feel the changes in conditions way in advance of those who are supposed to be responsible for their welfare. But with all these abilities there is one big organic weakness. Over and over again workers in various shops and industries, faced with a critical issue, only divide and become disunited, even though they are well aware that they are being unprincipled and weakening their own cause as workers. Since the advent of automation there has not been any serious sentiment for striking, particularly if the strike was going to come at the expense of material things that the workers already had in their possession, like cars, refrigerators, TV sets, etc. They were not ready to make any serious sacrifices of these; they would rather sacrifice the issue. Between the personal things and the issue, they have chosen the personal. Most American workers have geared themselves to a standard of living that is based on a five-day week plus—either in the form of overtime or another job, part or full time. And any time this standard of living is threatened, it is a personal crisis, which means that more and more decisions are being personalized and individualized rather than collectivized and socialized.”

(The American Revolution: Pages From a Negro Worker’s Notebook, James Boggs, Monthly Review Press, 1963, page 33)

As far back as 1963, with President John Kennedy in office, James Boggs (a Detroit autoworker) was already quite aware of automation and its challenges.

A “meta-intelligent” education means we learn from any sources available including “angry pamphlets” without worrying about the ideological blinders or fireworks because our desire is not to engage in polemics but to “extract signals” from a noisy world.

Chapter 2 of James Boggs’s pamphlet is called “The Challenge of Automation” and begins: “Since 1955 and the advent of automation, overtime has been detrimental to the workers…”

This immediately tells you that automation is a very long-run historical trend and should be seen in a larger sweep with history as your searchlight.

Indeed the famous German classic The Weavers by Gerhart Hauptmann is about machines as a threat to employment:

The Weavers (German: Die Weber, Silesian German: De Waber) is a play written by the German playwright Gerhart Hauptmann in 1892. The play sympathetically portrays a group of Silesian weavers who staged an uprising during the 1840s due to their concerns about the Industrial Revolution and replacement by machines and automation.

In 1927, it was adapted into a German silent film The Weavers, directed by Frederic Zelnik and starring Paul Wegener.

A Broadway version of The Weavers was staged in 1915–1916.

To dismiss all such movements and revolts as Luddite-like is not useful since it sweeps legitimate problems under the rug.

This includes Ernst Toller’s classic The Machine Wreckers (German: Die Maschinenstürmer). Two of his early plays were produced in this period: The Machine Wreckers (1922), whose opening night in 1937 he attended, and No More Peace, produced in 1937 by the Federal Theatre Project and presented in New York City in 1938.

All of these critiques of machines and automation are part of a long-term historical overview of machines and jobs and in our time, robotics and AI, etc which should be analyzed as a trajectory and arc where “machine wreckers” à la Hauptmann or Toller are understood empathetically and realistically and not dismissed as vandals.

Education and the World’s Confusion

Students need to understand that the world and history and the mood of the moment are always a “confusing swirl,” as experience shows, and that implies the present intersection of world/history/mood is also such a confusing “opaque windshield.”

Take the example of Europe after World War I. Mussolini leaves his position at the left-wing paper Avanti! (English: “Forward”) and founds the bellicose Il Populo d’Italia (English: “The People of Italy”), which is nationalist and warlike.

Avanti! was an Italian daily newspaper, born as the official voice of the Italian Socialist Party, published since 25 December 1896. It took its name from its German counterpart Vorwärts, the party-newspaper of the Social Democratic Party of Germany. Il Populo d’Italia, was an Italian newspaper which published editions every day with the exception for Mondays founded by Benito Mussolini in 1914, after his split from the Italian Socialist Party.

Mussolini was a complete tactical opportunist and his profound flip-flops indicate that “the winds” of mood and opinion were capricious and somewhat blind to its own twists and turns.

Take the case of the (later) famous anti-fascist Arturo Toscanini, the great music conductor. His trajectory is non-linear and as “jumpy” as Mussolini’s, going the other way:

“From the start Fascism was an eclectic movement and in its early days in 1919 it attracted a number of people who, including some, such as the great conductor Arturo Toscanini, who soon became its most determined opponents.”

(James Joll, Europe since 1870: An International History, Penguin Books, 1976, page 266)

Toscanini ran as a Fascist parliamentary candidate in Milan (1919) and this is a clue as to the tremendous disorientation in the wake of World War I.

In 1983, the outstanding Hebrew University scholar, Professor Sternhell, wrote Ni droite ni gauche. L’idéologie fasciste en France, which was translated to English three years later under the title, Neither Right nor Left: Fascist Ideology in France. The title of this classic by Sternhell—“neither right nor left”—captures via its very title, the indeterminate fusion and hodge-podge quality of modern ideologies. If they’re neither right nor left, where are they?

We could say there’s a deep pattern: World War I (yielding communism and fascism and Nazism) and then World War II (with atomic weapons and Auschwitz) and the Cold War have all left very disorienting legacies and since people in 2022 are legatees of these three wars, outlooks are very foggy. As the world becomes extremely confusing, people react accordingly and veer from mood to mood and opinion to opinion.

Education and Ambiguity Awareness: A Polyvalent World

Sleepwalkers and sleepwalking are both destructive and constructive and show us the ambiguity in all phenomena.

The World War I chronicle of Professor Christopher Clark, The Sleepwalkers, from 2012, is described this way:

On the morning of June 28, 1914, when Archduke Franz Ferdinand and his wife, Sophie Chotek, arrived at Sarajevo railway station, Europe was at peace. Thirty-seven days later, it was at war. The conflict that resulted would kill more than fifteen million people, destroy three empires, and permanently alter world history.

The Sleepwalkers reveals in gripping detail how the crisis leading to World War I unfolded. Drawing on fresh sources, it traces the paths to war in a minute-by-minute, action-packed narrative that cuts among the key decision centers in Vienna, Berlin, St. Petersburg, Paris, London, and Belgrade.

Distinguished historian Christopher Clark examines the decades of history that informed the events of 1914 and details the mutual misunderstandings and unintended signals that drove the crisis forward in a few short weeks.

How did the Balkans—a peripheral region far from Europe’s centers of power and wealth—come to be the center of a drama of such magnitude? How had European nations organized themselves into opposing alliances, and how did these nations manage to carry out foreign policy as a result? Clark reveals a Europe racked by chronic problems—a fractured world of instability and militancy that was, fatefully, saddled with a conspicuously ineffectual set of political leaders. These rulers, who prided themselves on their modernity and rationalism, stumbled through crisis after crisis and finally convinced themselves that war was the only answer.

On the other hand, the great science writer and intellectual Arthur Koestler (died in 1983) in his own book, The Sleepwalkers, (originally, 1959) argues that the revolution in cosmology associated with the names of Copernicus, Kepler, Galileo, et al depended on visionary thinking, a kind of “sleepwalking.”

Lastly, the classic novel, The Sleepwalkers by Hermann Broch (died in 1851) condemns sleepwalking as the basis of Europe and Germany’s descent into nightmare.

Important works by Broch are The Sleepwalkers (German: “Die Schlafwandler,” 1932) and The Guiltless (German: “Die Schuldlosen,” 1950). The Sleepwalkers is a trilogy, where Broch takes “the degeneration of values” as his theme. Various generations are depicted as sleepwalking through their times and eras without any ability to “see past” their time, place, era. They were “sleepwalking.” This made them liable to demagogic deceptions and recruitment.

On the other hand, the experience and story of Kekulé (died 1896) and his scientific discoveries prodded by dreams and reveries and sleepwalking give us a story that argues against seeing sleepwalking as always negative:
Kekulé’s dream and “good kinds of sleepwalking.”

Friedrich August Kekulé, later Friedrich August Kekule von Stradonitz (7 September 1829 – 13 July 1896), was a German organic chemist. From the 1850s until his death, Kekulé was one of the most prominent chemists in Europe, especially in theoretical chemistry. He was the principal founder of the theory of chemical structure.

The new understanding of benzene (C6H6), and hence of all aromatic compounds, proved to be so important for both pure and applied chemistry after 1865 that in 1890 the German Chemical Society organized an elaborate appreciation in Kekulé’s honor, celebrating the twenty-fifth anniversary of his first benzene paper.

Here Kekulé spoke of the creation of the theory.

He said that he had discovered the ring shape of the benzene molecule after having a reverie or day-dream of a snake seizing its own tail (this is an ancient symbol known as the ouroboros).

Kekulé’s story of “dreaming up” the structure of benzene (C6H6) gives us another historical example of Arthur Koestler-type “good sleepwalking” ie visionary dreams and reveries that really enhance “objective” concrete scientific analysis and not only art works.

It is educational to see the inner ambiguity of words and phenomena (such as sleepwalking) because this duality and “polyvalence” applies to many cases.
