World-Watching: U.S. Greenlighted H20 Chips Export on Its Own Initiative, China Says

Beijing clarifies its deal with Washington didn’t include NVIDIA’s 4th-best AI chip, disputing widely-reported comments by U.S. Commerce Secretary Howard Lutnick

by Zichen Wang, from Pekingnology

The U.S. greenlighted NVIDIA’s China-specific Artificial Intelligence chip, known as the H20, for export to China on its own initiative, China said on Friday.

In a statement dedicated to the recent U.S. approval of the semiconductor giant’s 4th-best Artificial Intelligence chip, China’s Ministry of Commerce said on its website that in early July, the U.S. had already lifted restrictions on China under the agreement reached between the two countries in London.

“We have taken note that Washington has now taken the initiative to announce it will authorize sales of NVIDIA’s H20 chips to China,” the trade ministry added.

Beijing’s clarification stands in stark contrast to widely reported public comments earlier this week by U.S. Commerce Secretary Howard Lutnick, who told Reuters on Tuesday that “We put that in the trade deal with the magnets,” referring to the agreement made to restart Chinese rare earth shipments to U.S. manufacturers. He did not provide additional details, according to Reuters.

NVIDIA’s H20 was designed to be technologically inferior. The company also sells three other chips that far surpass the H20’s power.

On Monday, July 14, the Silicon Valley company announced in a blog post that the U.S. government had approved the sale of the H20, three months after the Donald Trump administration shut down NVIDIA’s artificial intelligence chip sales to China, after CEO Jensen Huang met President Trump in Washington D.C., and before he departed for Beijing.

Huang dominates Chinese headlines this week with his speech at an industry conference and public events with Chinese AI leaders. He visited China’s Ministry of Commerce and was received by Wang Wentao, the minister, on Thursday.

MOFCOM Spokesperson Responds to Questions on the U.S. Approval of NVIDIA H20 Chip Sales to China

2025-07-18 13:43

Question:

U.S. officials have recently stated that Washington’s decision to approve sales of NVIDIA’s H20 chips to China is part of ChinaU.S. economic and trade negotiations. They also claimed that Chinese firms, including Huawei, are already producing equivalent chips domestically and that the United States does not want China to achieve full import substitution. How does the Ministry of Commerce (MOFCOM) view this?

Answer:

Following the ChinaU.S. economic and trade consultations in London, the two sides have maintained close communication, finalized the “London framework,” and moved forward with implementation. China, in accordance with its laws and regulations, approves export applications for controlled items that meet the necessary criteria. In early July, the United States reciprocally lifted the restrictions on China that had been discussed during those talks.

We have taken note that Washington has now taken the initiative to announce it will authorize sales of NVIDIA’s H20 chips to China. Beijing believes the United States should abandon a zero-sum mentality and continue to roll back a range of unwarranted trade and technology restrictions on China.

Cooperation and mutual benefit are the only viable path; suppression and containment lead nowhere. In May, the United States issued new export-control guidelines targeting Huawei’s Ascend chips, tightening restrictions on Chinese semiconductor products under unfounded pretexts. By wielding administrative power to distort fair market competition, these measures severely undermine the legitimate rights and interests of Chinese companies. China has made its position clear and firmly opposes such actions.

We look forward to the United States working with China in a spirit of equality to correct these erroneous practices, foster a sound environment for mutually beneficial cooperation between the two countries’ enterprises, and jointly safeguard the stability of global semiconductor supply chains.

Navigating through Sources

Consciousness and the Novel: Connected Essays by the famous British novelist David Lodge is a classic work published by Harvard in 2004.

In this Lodge book, the author mentions a famous British society-watcher, Charles Masterman. In 1909, Masterman published his best-known study, The Condition of England, which tells us that England at that time experienced a greater inflow of migrants into London than in previous centuries taken together.

[Charles Frederick Gurney Masterman PC MP (24 October 1873 – 17 November 1927) was a British radical Liberal Party politician, intellectual and man of letters. He worked closely with such Liberal leaders as David Lloyd George and Winston Churchill in designing social welfare projects, including the National Insurance Act 1911. During the First World War, he played a central role in the main government propaganda agency.]

We then notice that one recurrent topic in various movie versions of the E. M. Forster novel Howards End (1910, set in those years) is the “horrifying” trend where great mansions and stately estates (Howards End and Wickham Place, say, in the novel) are all being demolished and replaced by ugly “flats.”

There must be, one thinks, a direct link between all the massive migrations into London at the time and all the proliferating flats at the “expense” of beautiful and historical villas. (This “demolish” trend is also part of the story of the classic novel A Handful of Dust by Evelyn Waugh, 1934)

In the predecessor to Downton Abbey called Upstairs, Downstairs, the story ends in 1930 with a sign outside the great “house” at Eaton Place offering flats coming soon, as the demand for housing (think of San Francisco today) is so massive that sellers can make a fortune selling out to developers, move into one of the flats being created, and live off the sale for the rest of their lives and “duck” the higher “Lloyd George taxes.” (In Downton Abbey, the dowager played by Maggie Smith repeatedly lashes out at Prime Minister Lloyd George as a kind of financial traitor.)

We see from this simple example how students should learn to “jump” between books and movies and TV miniseries to get a stronger focus on what’s being depicted on screens and pages and not just “swim along” at the surface level without any “drilling down.”

Education is largely the struggle or habit where students learn to bring pattern and structure out of “chaos,” thus giving narratives some overall shape.

This reminds one of the opening lines of Beryl Markham’s 1942 Africa memoir:

“How is it possible to bring order out of memory? I should like to begin at the beginning, patiently, like a weaver at his loom. I should like to say, ‘This is the place to start; there can be no other.’ ”

from West with the Night by Beryl Markham

This is a similar impetus: to bring order out of memory or others’ memories in books and movies from various times and places.

Movies as a Parallel University: The Case of Romantic Imperialism

When we think of romantic imperialism, we think of Rudyard Kipling’s poems, Winston Churchill’s The River War and perhaps Teddy Roosevelt’s macho “strenuous life” romanticized militarism (which the neocons somewhat knowingly aped to get the U.S. to invade Iraq in 2003). We should also recall British movie classics like The Four Feathers and “deflationary” versions of these jingoistic notions in The Man Who Would be King. During the 1930s, the Hungarian brothers Alexander & Zoltan Korda created many classic empire-celebration films in London, such as 1935’s Sanders of the River.

The Nigerian writer Chinua Achebe’s attack on Joseph Conrad’s Heart of Darkness as a kind of toxic “othering” of all Africans is a culmination of these imperial and anti-imperial tendencies.

Lastly, Maupassant’s classic Bel-Ami represents Algeria as a “colonial badlands” for French domination, killing, despoiling, profiteering, and later culminates in Meursault’s random murder of an Arab again in Algeria in Camus’ classic The Stranger. This literary concatenation also fits into this set of colonial imperial phenomena.

Niall Ferguson (the famous Harvard/Stanfordempire enthusiast”) finds his forerunner in the 1940 classic movie Beyond Tomorrow. The following “row” takes place on Christmas Eve between Chadwick (the Niall Ferguson imperialist) and Melton who sees empire as land-grabbing which you can dress up and prettify any way you like (“a grab is a grab,” he says):

Allan Chadwick: I tell you England’s territorial expansion had quite a different significance.

George Melton: No matter how thin you slice it, a grab is a grab.

Allan Chadwick: Grab?

That’s a specious term. England carried civilization into the wilderness. What was Australia before she redeemed it from the Aborigines?

Allan Chadwick: The truth is there isn’t an acre of the Empire that isn’t proud to fly the British flag.

The quick irritated exchange from Beyond Tomorrow is a good example of this eternal argument, allowing you to then “jump off” from this movie-as-university to do more exploring.

Education and the Historical Swirl: Part II

We concluded Part I on this topic with the following comments which we wish students to incorporate into their educations, irrespective of the major, field or concentration:

The gold standard itself, dominated from London led to intricate problems: Golden Fetters: The Gold Standard and the Great Depression, 1919-1939 (published in 1992) by Barry Eichengreen, the leading historian of monetary systems, shows the downstream pitfalls of the gold standard.

In other words, the de facto emergence of Britain/London as the world commercial and policy center and the relation of this emergence to empire and international tensions and rivalries, means it is very problematical for any country to steer a course other than staying in tandem with British moods and ideologies, such as free trade. Any country by itself would find it difficult to have a more independent policy. (Friedrich List of Germany, who died in 1846, wrestles with these difficulties somewhat.) The attempts to find “autonomy and autarky” in the interwar years (Germany, Japan, Italy) led to worse nightmares. The world seems like a “no exit” arena of ideologies and rivalries.

The “crazy dynamics” and the semi-anarchy of the system, which continues to this day and is even worse, means that policy-making is always seen through a “dark windshield.”

History in the globalizing capitalist centuries, the nineteenth and the twentieth, is a kind of turbulent swirl and not a rational “walk.”

Here’s a bizarre but necessary comment on this sense of turbulent and surprising swirl propelling history forwards and backwards and sidewards at the same time:

The historian, Barry Eichengreen (mentioned above), is a distinguished analyst of world monetary systems at U.C. Berkeley and perhaps the leading expert today on the evolution of such systems.

From movies such as Shoah and Last of the Unjust by the great filmmaker Claude Lanzmann, we know that Barry Eichengreen’s mother was Lucille Eichengreen, a Jew born in Hamburg, Germany (1925) and deported to the Łódź Ghetto in Poland during World War II. She survived through many miraculous accidents and contingencies, then wrote about her experiences.

We get a deeper insight into “the way of the world” by seeing that the Holocaust itself has as a backdrop the anarcho-craziness of the world. The Fascists and Nazis were jumping from the “frying pan into the fire” by imagining that world conquest and world-murdering could “stop the world.” They and their favored populations could “get off” and step into a racial dreamworld. They were taking today’s concept of “gated community” and applying it to the “racial community” (Volksgemeinschaft, in German).

This led to the phenomenon depicted in Goya’s famous aquatint: The Sleep of Reason Produces Monsters.

The perceived madness of the world and the madness of leaders that this perception leads to have never been analyzed together.

The fact that the behavior of world leaders could be “crazy like a fox” (half-insane, half-opportunistic, or Machiavellian “clever”) is a complicating factor or twist from Mussolini until today.

Education: Disease, History and Lit

The Italian writer Giovanni Boccaccio lived through the plague as it ravaged the city of Florence in 1348. The experience inspired him to write The Decameron.

The Plague of 1665 in England was a major upheaval affecting Isaac Newton’s life.

The 1984 movie, A Passage to India (David Lean) set in 1920s India, has a scene where the ever-present lethal threat of cholera is discussed as Doctor Aziz lies sick of a fever.

The W. Somerset Maugham novel, The Painted Veil (2006 movie) is also about cholera in the Chinese countryside in the 1920s.

Manzoni’s 1827 The Betrothed, the most famous classic novel of Italian literature, centers on the plague to drive the story.

Overview:

Etymologically, the term “pest” derives from the Latin word “pestis” (pest, plague, curse). Hardly any disease had such cultural and historical relevance as the bubonic plague. Throughout the centuries, the plague was the most terrifying infectious contagious disease which generated a series of demographic crises. The plague epidemics influenced the evolution of society biologically and culturally speaking. The Black Death was one of the most devastating pandemics in human history, is estimated to have killed 30%–60% of Europe’s population, reducing the world’s population from an estimated 450 million to between 350 and 375 million in 1400. This has been seen as having created a series of religious, social and economic upheavals, which had profound effects on the course of European history. It took 150 years for Europe’s population to recover.

The plague returned at various times, killing more people, until it left Europe in the 19th century. Modern epidemiology (Dr. John Snow, London) has its roots in cholera management and water sanitation as well as waste management.

Education involves seeing disease as a major protagonist in all history and not as a footnote.

The classic Plagues and Peoples should accordingly be studied by every student: Plagues and Peoples is a book on epidemiological history by William Hardy McNeill, published in 1976.

It was a critical and popular success, offering a radically new interpretation of the extraordinary impact of infectious disease on cultures and world history itself.

Education and the World As “Rorschach Test”

The Rorschach test is a projective psychological test in which subjects’ perceptions of inkblots are recorded and then analyzed using psychological interpretation, complex algorithms, or both. Some psychologists use this test to examine a person’s personality characteristics and emotional functioning.

It is also called “an Inkblot test.”

We use this test as a metaphor that suggests that people see what they want to see and choose to see.

Here’s an example based on the Verdi opera La Forza del Destino. The black intellectual leader, William E.B. Du Bois, sees it as a veiled racial story where Professor Niall Ferguson of Stanford/Harvard tells the story of how he emerged from a performance of the opera on the very day that Britain devalued the pound sterling in 1992.

Black Wednesday refers to September 16, 1992, when a collapse in the pound sterling forced Britain to withdraw from the European Exchange Rate Mechanism (European Monetary System).

Thus the opera, La Forza del Destino is both a Verdi opera and a kind of “raw material” for personal and private interpretation with Du Bois seeing racism and Ferguson seeing national or financial fate.

La Forza del Destino or The Power of Fate, (often translated The Force of Destiny) is an Italian opera by Giuseppe Verdi. The libretto was written by Francesco Maria Piave based on a Spanish drama, Don Álvaro o la fuerza del sino (1835), by Ángel de Saavedra, 3rd Duke of Rivas, with a scene adapted from Friedrich Schiller’s Wallensteins Lager. It was first performed in the Bolshoi Kamenny Theatre of Saint Petersburg, Russia, on 10 November, 1862 O.S. (N.S. 22 November).

Synopsis—Act 1

The mansion of Leonora’s family, in Seville.

Don Alvaro is a young nobleman from South America (presumably Peru) who is part Indian and who has settled in Seville where he is not very well regarded.

He falls in love with Donna Leonora, the daughter of the Marquis of Calatrava, but Calatrava is determined that she shall marry only a man of the highest birth. Despite knowing her father’s aversion to Alvaro, Leonora is deeply in love with him, and she determines to give up her home and country in order to elope with him. In this endeavor, she is aided by her confidante, Curra. (Me pellegrina ed orfana—“Exiled and orphaned far from my childhood home”).

When Alvaro arrives to fetch Leonora, she hesitates: she wants to elope with him, but part of her wants to stay with her father; she eventually pulls herself together, ready for their elopement. However, the Marquis unexpectedly enters and discovers Leonora and Alvaro together. He threatens Alvaro with death, and in order to remove any suspicion as to Leonora’s purity, Alvaro surrenders himself. As he flings down his pistol, it goes off, mortally wounding the Marquis, who dies cursing his daughter.

This is the racial aspect on which W.E.B. Du Bois focuses.

Niall Ferguson, by contrast, sees a different “Rorschach inkblot” and hones in on the financial policy story which went like this:

Soros’ Quantum Fund began a massive sell-off of pounds on Tuesday, 15 September 1992. The Exchange Rate Mechanism stated that the Bank of England was required to accept any offers to sell pounds. However, the Bank of England only accepted orders during the trading day. When the markets opened in London the next morning, the Bank of England began their attempt to prop up their currency as per the decision made by Norman Lamont and Robin Leigh-Pemberton, the then Chancellor of the Exchequer and Governor of the Bank of England respectively. They began buying orders to the amount of 300 million pounds twice before 8:30 AM to little effect.

The Bank of England’s intervention was ineffective because Soros’ Quantum Fund was dumping pounds far faster. The Bank of England continued to buy and Quantum continued to sell until Lamont told Prime Minister John Major that their pound purchasing was failing to produce results.

At 10:30 AM on 16 September, the British government announced a rise in the base interest rate from an already high 10 to 12 percent to tempt speculators to buy pounds. Despite this and a promise later the same day to raise base rates again to 15 percent, dealers kept selling pounds, convinced that the government would not stick with its promise. By 7:00 that evening, Norman Lamont, then Chancellor, announced Britain would leave the ERM and rates would remain at the new level of 12 percent; however, on the next day the interest rate was back on 10%.

It was later revealed that the decision to withdraw had been agreed at an emergency meeting during the day between Norman Lamont, Prime Minister John Major, Foreign Secretary Douglas Hurd, President of the Board of Trade Michael Heseltine, and Home Secretary Kenneth Clarke (the latter three all being staunch pro-Europeans as well as senior Cabinet Ministers), and that the interest rate hike to 15% had only been a temporary measure to prevent a rout in the pound that afternoon.”

For W.E.B. Du Bois, the story within the story of the Verdi opera is the color-line that governs the world, while Ferguson sees the story as a “dramatic” instance of financial and economic force or working out of trends that becomes a destiny.

Hence people see what they choose to see and interpreting and seeing are wrapped up in each other.

Students should assimilate this aspect of the world.

Note: one source of the Du Bois interpretation of the opera comes from the University of Chicago book, Travels in the Reich: 1933-1945 (edited by Oliver Lubrich, 2012) which has a chapter on Du Bois in Germany in the thirties where he plunges into music and opera and highlights this Verdi one.

Education and Seeing the “Swirl” of History

The tempo and rhythm of world events and world history are not captured in the linear and bland books one reads in schools and colleges where the sense of the stormy forward turbulence of the world is not communicated. Here’s an example that does communicate this “crazy dynamics”:

The leading historian, James Joll, in his excellent Europe Since 1870: An International History talks about gold and the gold standard in this way:

“The world supply of gold was diminishing, as the effects of the gold rushes in California and Australia in the 1850s and 1860s passed. This coincided with the decision in the 1870s of many of the leading countries to follow Britain’s example to use gold rather than silver as the basis of their currencyGermany in 1871, France in 1876 for example — so that the demand for gold rose just as the supply was temporarily declining. This in turn led to some doubt about the use of a gold standard and to much discussion about ‘bi-metallism’ and about the possibility of restoring silver to its place as the metal on which the world’s currency should be based, though this movement had more success in the United States than in Europe, where gold has now established itself firmly. By the 1890s however the discovery of new gold deposits in South Africa, Western Australia and Canada put an end to these discussions and uncertainties, as far as currency was concerned, for some fifty years.”

(James Joll, Europe Since 1870: An International History, Penguin Books, 1976, page 35)

These twists and turns and accidents or contingencies don’t communicate the real semi-turmoil surrounding all the decisions, which we can infer from the comment by a German politician in 1871, “We chose gold, not because gold was gold, but because Britain was Britain.” (Ian Patrick Austin, Common Foundations of American and East Asian Modernisation: From Alexander Hamilton to Junichero Koizumi, Select Publishing, 2009, page 99.)

Professor Joll delineates the emergent primacy of England:

“The establishment of London as the most important center in the world for shipping, banking, insurance-broking and buying and selling generally, as well as the growth of British industry, had been based on a policy of free trade.”

(James Joll, Europe Since 1870: An International History, Penguin Books, 1976, page 34)

The gold standard itself, dominated from London led to intricate problems: Golden Fetters: The Gold Standard and the Great Depression, 1919-1939 (published in 1992) by Barry Eichengreen, the leading historian of monetary systems, shows the downstream pitfalls of the gold standard.

In other words, the de facto emergence of Britain/London as the world commercial and policy center and the relation of this emergence to empire and international tensions and rivalries, means it is very problematical for any country to steer a course other than staying in tandem with British moods and ideologies, such as free trade. Any country by itself would find it difficult to have a more independent policy. (Friedrich List of Germany, who died in 1846, wrestles with these difficulties somewhat.) The attempts to find “autonomy and autarky” in the interwar years (Germany, Japan, Italy) led to worse nightmares. The world seems like a “no exit” arena of ideologies and rivalries.

The “crazy dynamics” and the semi-anarchy of the system, which continues to this day and is even worse, means that policy-making is always seen through a “dark windshield.”

History in the globalizing capitalist centuries, the nineteenth and the twentieth, is a kind of turbulent swirl and not a rational “walk.”

Movies as a Parallel University: Cola Wars Movie

The 1961 fast-paced comedy, One, Two, Three starring James Cagney is extremely informative in a certain way if you get beyond the farcical and “manic-jocular” tone and atmosphere.

The story takes place in West Berlin. Communism and Nazism are still “in the air,” although Germany has of course been defeated in 1945.

C.R. “Mac” MacNamara (James Cagney) is a high-ranking executive in the Coca-Cola Company, assigned to West Berlin after a business fiasco a few years earlier in the Middle East (about which he is still bitter). While based in West Germany for now, Mac is angling to become head of Western European Coca-Cola Operations, based in London. After working on an arrangement to introduce Coke into the Soviet Union, Mac receives a call from his boss, W.P. Hazeltine, at the Coca-Cola headquarters in Atlanta. Scarlett Hazeltine, the boss’s hot-blooded but slightly dim 17-year-old socialite daughter, is coming to West Berlin. Mac is assigned the unenviable task of taking care of this young whirlwind.

The undiscussed and “latent content” of this zany comedy is very serious.

There are three fundamental choices for a country:

  1. Class war (Communism, Eastern Bloc, Russia).
  2. Race war (Nazis, Germany, fascism).
  3. Cola war (Coke versus Pepsi, USA, business civilization).

The implicit message of the movie, which constitutes a kind of ultimate political science lesson, is that cola wars (i.e., corporate competition for sales and profits and markets worldwide) is the best choice, no matter that it seems manic and empty, since the alternatives on the list of three options are impractical nightmares which lead to calamities and historical catastrophes.

The basic book describing the cola wars factually is: The Cola Wars: The Story of the Global Battle between the Coca-Cola Company and PepsiCo, Inc., J.C. Louis & Harvey Z. Yazijian, Everest House, October 1, 1980.

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.
