Raymond Aron, Jean-Paul Sartre, and the Limits of Being Right

World-famous philosopher Jean-Paul Sartre was not the best student in his graduate school class. That was Raymond Aron (1905-1983), who had the top score on their exams and then won a prize for his dissertation on Max Weber and the philosophy of history. Then the careers of that whole generation were derailed by World War II. Aron at least was not surprised, since had had been in Germany in 1933 and came back telling everyone that war was inevitable. After France fell to the Nazis, Sartre hung around Paris, womanizing and wrestling with philosophical concepts too obscure for the Gestapo to care what he was up to. Aron fled to London to serve the Free French cause and ended up editing their newspaper.

After the war Europe was divided into democratic and communist camps, and Sartre led most of France’s intellectuals in championing communism. This was a decade after Stalin’s show trials that made it clear to anyone paying attention what his regime was like, but Sartre still found ways to justify everything. While Stalin’s thugs were clamping down in eastern Europe and killing or jailing thousands of “enemies of socialism,” Sartre was singing the praises of revolution. Sartre’s philosophy was very much concerned with self knowledge, with avoiding the “bad faith” of deceiving yourself. He wrote even more about the problem of freedom and what it means; his most famous work, Nausea, features a character who experiences his own freedom as a sickness. And yet all of his wrestling with nausea and staring into the face of nothingness somehow always brought him back to the party line.

Meanwhile Sartre’s old friend and classmate Raymond Aron had become one of France’s leading anti-communists. He grew so angry with the callous way Sartre (and Simone de Beauvoir) justified Stalin’s brutalities that he published a letter declaring their friendship at an end. Aron moved on from philosophy to sociology and history, but his politics were so unfashionable in the postwar years that he had to wait until 1955 before he received a professorship. Meanwhile he continued to work as a journalist and to write books. In 1955 he published The Opiate of the Intellectuals (1955), a frontal assault on the communist enthusiasms of his French intellectual peers that regularly appears on lists of the most influential books of the twentieth century. Aron wrote,
The man who no longer expects miraculous changes either from a revolution or from an economic plan is not obliged to resign himself to the unjustifiable. It is because he likes individual truth, that he refuses to surrender his soul to an abstract ideal of humanity, a tyrannical party, and an absurd scholasticism. . . . If tolerance is born of doubt, let us teach everyone to doubt all the models and utopias, to challenge all the prophets of redemption and the heralds of catastrophe.
But that was just one of more than forty books that Aron wrote. His main topics were sociology and what we might call the philosophy of social science, that is, what it means to interpret or understand complex human societies, what counts for evidence, and what are the limits to our understanding of the modern human world. But he also wrote about modern history, French politics, Israel – Aron was a Jew who hated the notion of a unified “Jewish people” and considered himself more French than Jewish – nuclear strategy, political science, the idea of progress, and more. His most widely read book these days may be War and Peace between Nations (1962), a highly regarded look at what “realism” in foreign relations really means.

Realism was an important word to Aron, since he considered himself above all a realist. Looking around the world in the 40s and 50s, he thought – like George Orwell, Arthur Koestler, and many others who also identified as realists – that the only real question in foreign policy was whether to ally with the Americans or the Soviets. It was no good to say that you did not like the Americans, or to complain that American capitalism, racism, and support for third world dictators was nearly as bad as whatever the Soviets were up to. It did not matter; there were only two powers in the world, and only a fool would think that France would be better off under Soviet dominance than in NATO. It was Aron’s pro-American views that brought him into conflict with de Gaulle, who considered it his mission in life to restore France’s sense of its own greatness. Aron found nationalism to be an ideology nearly as dangerous as communism, and he regarded de Gaulle’s search for Gloire absurd. Thus although Aron was generally seen as a man of the Right and wrote for a conservative newspaper, he was not comfortable with Gaullism or any other branch of conservatism. He was too independent, too skeptical that any one point of view was enough. He was an insider of sorts, but never in the true circles of power; he was offered important government posts on several occasions but he always refused. He disliked the loss of intellectual freedom that joining a government involved, did not want to be careful about what he said. He especially disliked the way de Gaulle used carefully vague words to preserve his freedom of action, making bold speeches that really committed him to nothing. If that was leadership – and it was, and is – Aron wanted no part of it.

On the big questions of his lifetime, Aron was right: he stood up for freedom against Hitler and then against Stalin, he worked for peace and democracy, he wanted France to give up its colonies and ally with the United States against communism. He was a great scholar, an important voice in French affairs, by almost any standard a huge success. At yet he considered himself a much smaller and less important man than many of those who were wrong, especially his old classmate Jean-Paul Sartre. Have you ever heard of him?

Aron knew that though he might be right, he was not cut out for greatness. He did not want to make the compromises necessary to participate in democratic politics, so he achieved nothing in that vein. His scholarly work consisted mainly of careful reviews of radical ideas produced by others, much weighing and assessing but few bold pronouncements. He had a habit, maddening to some critics, of ending long essays and even books with a question mark. With him everything was tentative, partial, uncertain, complex. He refused to over-simplify. He also refused to be moved by the sort of intentionally obscure language used by philosophers such as Hegel and Sartre. What, he asked, repeatedly, does this really mean? And yet accuracy of language and fidelity to reality as we understand it will only get you so far. As Stanley Hoffman wrote,
But what would be left of this huge mass of writings? Aron often expressed his own doubts. He always put “creators” above “critics”: Sartre, for all his political divagations, was a creator, Aron, for all his lucidity, was only a critic. His conception of man and of history made him impatient with what he called halftruths, prophecies based on a powerful but partial central intuition, such as Marx’s or Freud’s. But he admired most those who had changed man’s way of thinking in this fashion, and he knew that he was not one of them.
One admirer called Aron “the supreme destroyer of confusions and illusions.”

So we come to one of the great paradoxes of scholarship, and perhaps of all human thought: to be right is only one goal among many and not the most important. To be bold and exciting matters more. The most famous thinkers are not the ones who come closest to the truth, but the ones who devise new ways of thinking or new vocabularies. This is true even when the newness is largely sham. The ideas of the big modern thinkers – Marx, Freud, Sartre, Foucault – consist partly of old ideas in new clothes and partly of nonsense; strip away the nonsense and the received wisdom and you are left with at most a small advance in real understanding. Yet by their style, their clever rhetoric, their thunderous pronouncements, these men changed the culture in ways no careful, modest thinker ever has.

Boldness has its place in philosophy. But one of the reasons twentieth-century politics turned so awful was that a whole generation let this intellectual fascination with radical ideas and bold solutions spill over into the actual business of government. Aron took his stand against this criminal nonsense. He fought for clarity of thought because he could see what bad philosophy might lead to when equipped with tanks and interrogation rooms. At times whole human societies have been swept by what seems like madness -- the Ghost Dance among the plains Indians, Revolution among French intellectuals. The attraction to extreme beliefs and extreme actions is universal in humanity, and from time to time it overwhelms our minds. But another side of humanity is also universal: practical, down-to-earth, simple, unmoved by passion. In an age where murderous passions killed 50 million humans and threatened our planet with destruction, Raymond Aron stood up for the other side of our minds. He talked sense. In his lifetime, that was what the world needed most.

Deep Sea Squid vs. Owlfish

The Monterrey Bay Aquarium regularly posts videos shot by its deep sea remotely operated vehicles. This one shows a deep sea squid (Gonatus onyx) trying to kill and eat an owlfish (Pseudobathylagus miller) many times its size.

Nunalleq

Nunalleq is an archaeological site in western Alaska that is rapidly eroding into the sea. You have no doubt heard how much it has warmed in the polar north, and how much less ice there is and so on. This is causing previously frozen landscapes to erode rapidly. At Nunalleq, the shore has retreated more than 30 feet (9 meters) in the past four years.

Nunalleq means "the old village." The site is 700 to 400 years old, and its location was always known to Yup’ik residents of the nearby village of Quinhagak. Several years ago they discovered their ancestral home was rapidly eroding, and in 2008 they began contacting archaeologists to help them recover their heritage before it all washed into the sea.

Archaeologists from the University of Aberdeen in Scotland answered the call, and they have an ongoing program to excavate and preserve material from the site. Project director Dr. Rick Knecht:
The first thing we found was a complete wooden doll with the original paint still on it. It’s quite incredible – leather, fur, plants, even 400-year-old grass that has been completely preserved intact because they’ve been frozen all this time. Instead of looking at stones and bones, like archaeologists usually look at, we’ve got wooden artefacts - pieces of organic material. The exposed archaeological site was rapidly eroding away because of global warming – you’ve got rising sea level, and the permafrost is melting. The soil is held together by the ice, so when the ice melts the soil becomes very vulnerable to marine erosion.
You can read more about the excavations at their website.

Meanwhile, look at this amazing stuff -- antler harpoon points above, and a wooden doll above that.

Then this utterly weird angry wooden thing.

A wooden mask, above, and a carved monster below. Fabulous things, and how refreshing that Native Alaskans and archaeologists are working closely together on this project.

Yuppies in a Tiny House

Portland professionals Lily Copenagle and Jamie Kennel had a dream of building a house to their own specifications. A common American dream, but their specifications were a little unusual. They wanted small. Their goal was to avoid the usual entanglements of homeownership -- “There’s so much more personal freedom in going smaller” said Kennel. One of Copenagle's goals was
a space that was small enough to vacuum completely in five minutes, within cord’s reach of a single outlet, so there wouldn’t have to be any unplugging and replugging of the vacuum cleaner.
 They ended up with this one room, 704-square-foot place. It's cute; and what would a childless couple need with more space anyway?

.Here's a fabulous idea -- save time doing laundry but putting the washer and dryer in the clothes closet. Lots more here.

Surrendering Our Privacy for What?

The latest on all the good work the NSA is doing to protect us from terrorism:
“We have not identified a single instance involving a threat to the United States in which the telephone records program made a concrete difference in the outcome of a counterterrorism investigation,” said the report, a copy of which was obtained by The Washington Post. “Moreover, we are aware of no instance in which the program directly contributed to the discovery of a previously unknown terrorist plot or the disruption of a terrorist attack.”

....In its assessment of the program’s value, the board scrutinized 12 terrorism cases cited by the intelligence community that involved information obtained through the Section 215 program. Even in cases where the data related to contacts of a known terrorism suspect, in nearly all of them the benefits were minimal—“generally limited to corroborating information that was obtained independently by the FBI,” the report said.
This is from a new commission report on the government's spying under Section 215 of the Patriot Act.

Stephen Hawking Rethinks Black Holes

Black holes are one of the places that our two models of the universe, quantum mechanics and general relativity, clash head on. It was shown decades ago that the simple model of black holes, derived from Einstein's equations, cannot be reconciled with quantum mechanics. In particular the notion of an "event horizon", a barrier from which no light, matter or information can ever escape, violates all sorts of quantum principles. Just this week Stephen Hawking posted a new paper tackling the problem. Nature News:
The paper is an attempt to solve the so-called black-hole firewall paradox, which has been vexing physicists for almost two years, after it was discovered by theoretical physicists Joe Polchinski and colleagues. In a thought experiment, the researchers asked what would happen to an astronaut unlucky enough to fall into a black hole. Event horizons are mathematically simple consequences of Einstein's general theory of relativity that were first pointed out by German physicist Karl Schwarzschild in 1916. In that picture, physicists had long assumed, the astronaut would happily pass through the event horizon, unaware of his or her impending doom, before gradually being pulled inwards — stretched out along the way, like spaghetti — and eventually crushed at the 'singularity', the black hole’s hypothetical infinitely dense core.

But on analysing the situation in detail, Polchinski’s team came to the startling realization that the laws of quantum mechanics, which govern particles on small scales, change the situation completely. Quantum theory, they said, dictates that the event horizon must actually be a transformed into a highly energetic region, or 'firewall', that would burn the astronaut to a crisp.

This was alarming because, while the firewall obeyed quantum rules, it flouted Einstein’s general theory of relativity. According to that theory, someone in free fall should perceive the laws of physics as being identical everywhere in the Universe — whether they are falling into a black hole or floating in empty intergalactic space. As far as Einstein is concerned, the event horizon should be an unremarkable place.

Now Hawking proposes a third, tantalizingly simple, option: Quantum mechanics and general relativity remain intact. But black holes simply do not have an event horizon to catch fire. The key to his claim is that quantum effects around the black hole cause spacetime to fluctuate too wildly for a sharp boundary surface to exist.

In place of the event horizon, Hawking invokes an “apparent horizon”, a surface along which light rays attempting to rush away from the black hole’s core will be suspended. In general relativity, for an unchanging black hole, these two horizons are identical, because light trying to escape from inside a black hole can only reach as far as the event horizon and will be held there, as though stuck on a treadmill. However, the two horizons can, in principle, be distinguished. If more matter gets swallowed by the black hole, its event horizon will swell and grow larger than the apparent horizon.
As Hawking notes, a real solution to this problem would require laws of physics that somehow reconcile quantum mechanics with relativity, but since that still seems a distant dream, we can probably expect a lot more work along these lines, using ordinary logic to try to resolve the incompatible mathematics of situations like the black hole boundary.

Today's Good News

The sun, like all stars of its type, is gradually getting hotter. A recent study concluded that in just 600 to 700 million years, it would vaporize so much of the earth's oceans that a runaway greenhouse would turn our planet into a second Venus.

But wait! Now there is an even newer study, arguing that this dire end won't come for at least a billion years, and perhaps 1.5 billion. A reprieve!

Whew.

Measles in Europe

This is part of an interesting map from the Council on Foreign Relations showing "Vaccine-Preventable Disease Outbreaks" worldwide. Red is measles, blue is rubella, brown is mumps. Notice that as one might expect there is a problem with vaccinating everyone in Pakistan, where there is constant fighting between the government and Taliban-allied tribes. And yet the problem there is no worse than in wealthy, peaceful western Europe. In Europe there are two problems: immigrant groups that are deeply suspicious of their governments, especially Roma, and Green parents who don't want their children to suffer from the evils of chemical medicine. In 2010, there were more than 30,000 reported cases of measles in the EU and 30 deaths.

I hate to say it, but I think it will take a massive outbreak with hundreds of deaths before we get this madness back under control.

Jose de Ribera

Jose de Ribera (1591-1652) was a Spanish Baroque artist who spent his working life in Italy. Hence he is often know as Jusepe de Ribera, and even signed many of his paintings that way. Once he discovered art he longed to study in Italy, and he was in Rome by 1611.

There he joined the Caravaggisti, the young followers of Caravaggio, who copied the master's artistic style and sometimes his ribald personal life as well. The influence of Caravaggio shows in de Ribera's Sense of Smell, 1614 -- note the black, black shadows and the sharp contrasts of color.

Or this Gregory the Great, 1615, with its bold colors and hard edges.

At that time the Kingdom of Naples was part of the Spanish Empire, and de Ribera had moved there by 1616; he lived in Naples for most of his life. There he ingratiated himself into the Spanish court and engaged in numerous intrigues; it was said that he set out to ruin rival painters with malicious gossip so as to reserve more commissions for himself and a small group of friends. He eventually married his daughter into the Neapolitan nobility -- not bad for a man whose father owned a shoe factory. (Penitent St. Peter, ca. 1620)

As a Caravaggisti de Ribera was a partisan in the great conflict roiling the Italian art world. The followers of Michelangelo and Raphael believed it was the artist's job to search for ideal beauty -- or ugliness or whatever -- and come as close these ideals in his work as he could. The followers of Caravaggio thought everything should be painted from nature. De Ribera developed a strongly naturalist style, and he was especially famous for his realistic old men. Like this Philosopher with a Compass (1630), which used to be identified as Archimedes. Now it is now generally thought to be Democritus, but it could be just any man who happened to be walking by the studio on the day de Ribera was painting this.

Or this St. Andrews (c. 1630) -- this is an old man's body.

In the nineteenth-century de Ribera was praised almost exclusively for his naturalism. This work is particularly famous, Clubfoot (1642). From the twisted foot to the bad teeth, this is a real beggar.

Another very famous work, The Old Usurer (1638)

A demon from Ixion, part of a series on the damned, a subject that was in vogue for a while after Titian did a set for the Queen of Hungary.


Details.

Although he was in many ways a follower of Caravaggio, de Ribera did not share the master's scorn for drawing. He worked out all of his compositions very carefully as drawings, and the surviving examples show that he was very skilled.

Although his paintings in the mode of Caravaggio were his most famous works, de Ribera could also work in a different style, in which all the figures were bathed in golden light. The Ascension of Mary Magdalen (c. 1630). Not really my thing, but at least it shows versatility.

But these -- wow. Above, an Apostle (1632 ) and below, Habakkuk.

Many of these pictures come from the catalog of a big de Ribera show at the Met a few years ago, which you can download in its entirety here.
