In an essay in the Wall Street Journal, Frans de Waal—C. H. Candler Professor of Primate Behavior at Emory University—offers a fascinating review of recent scientific studies that upend long-held expectations about the intelligence of animals. De Waal rehearses a catalogue of fantastic studies in which animals do things that scientists have long thought they could not do. Here are a few examples:
Ayumu, a male chimpanzee, excels at memory; just as the IBM computer Watson can beat human champions at Jeopardy, Ayumu can easily best the human memory champion in games of memory.
Similarly, Kandula, a young elephant bull, was able to reach some fragrant fruit hung out of reach by moving a stool over to the tree, standing on it, and reaching for the fruit with his trunk. I’ll admit this doesn’t seem like much of a feat to me, but for the researchers de Waal talks with, it is surprising proof that elephants can use tools.
Scientists may be surprised that animals can remember things or use tools to accomplish tasks, but any one raised on children’s tales of Lassie or Black Beauty knows this well, as does anyone whose pet dog opened a door knob, brought them a newspaper, or barked at intruders. The problem these studies address is less our societal view of animals than the overly reductive view of animals that de Waal attributes to his fellow scientists. It’s hard to take these studies seriously as evidence that animals think in the way that humans do.
Seemingly more interesting are experiments with self-recognition and also facial recognition. De Waal describes one Asian Elephant who stood in front of a mirror and “repeatedly rubbed a white cross on her forehead.” Apparently the elephant recognized the image in the mirror as herself. In another experiment, chimpanzees were able to recognize which pictures of chimpanzees were from their own species. Like my childhood Labrador who used to stare knowingly into the mirror, these studies confirm that animals are able to recognize themselves. This means that animals do, likely, understand that they are selves.
For de Waal, these studies have started to upend a view of humankind's unique place in the universe that dates back at least to ancient Greece. “Science,” he writes, “keeps chipping away at the wall that separates us from the other animals. We have moved from viewing animals as instinct-driven stimulus-response machines to seeing them as sophisticated decision makers.”
The flattening of the distinction between animals and humans is to be celebrated, De Waal argues, and not feared. He writes:
Aristotle's ladder of nature is not just being flattened; it is being transformed into a bush with many branches. This is no insult to human superiority. It is long-overdue recognition that intelligent life is not something for us to seek in the outer reaches of space but is abundant right here on earth, under our noses.
DeWaal has long championed the intelligence of animals, and now his vision is gaining momentum. This week, in a long essay called “One of Us” in the new Lapham’s Quarterly on animals, the glorious essayist John Jeremiah Sullivan begins with this description of similar studies to the ones DeWaal writes about:
These are stimulating times for anyone interested in questions of animal consciousness. On what seems like a monthly basis, scientific teams announce the results of new experiments, adding to a preponderance of evidence that we’ve been underestimating animal minds, even those of us who have rated them fairly highly. New animal behaviors and capacities are observed in the wild, often involving tool use—or at least object manipulation—the very kinds of activity that led the distinguished zoologist Donald R. Griffin to found the field of cognitive ethology (animal thinking) in 1978: octopuses piling stones in front of their hideyholes, to name one recent example; or dolphins fitting marine sponges to their beaks in order to dig for food on the seabed; or wasps using small stones to smooth the sand around their egg chambers, concealing them from predators. At the same time neurobiologists have been finding that the physical structures in our own brains most commonly held responsible for consciousness are not as rare in the animal kingdom as had been assumed. Indeed they are common. All of this work and discovery appeared to reach a kind of crescendo last summer, when an international group of prominent neuroscientists meeting at the University of Cambridge issued “The Cambridge Declaration on Consciousness in Non-Human Animals,” a document stating that “humans are not unique in possessing the neurological substrates that generate consciousness.” It goes further to conclude that numerous documented animal behaviors must be considered “consistent with experienced feeling states.”
With nuance and subtlety, Sullivan understands that our tradition has not drawn the boundary between human and animal nearly as securely as de Waal portrays it. Throughout human existence, humans and animals have been conjoined in the human imagination. Sullivan writes that the most consistent “motif in the artwork made between four thousand and forty thousand years ago,” is the focus on “animal-human hybrids, drawings and carvings and statuettes showing part man or woman and part something else—lion or bird or bear.” In these paintings and sculptures, our ancestors gave form to a basic intuition: “Animals knew things, possessed their forms of wisdom.”
Religious history too is replete with evidence of the human recognition of the dignity of animals. God says in Isaiah that the beasts will honor him and St. Francis, the namesake of the new Pope, is famous for preaching to birds. What is more, we are told that God cares about the deaths of animals.
“In the Gospel According to Matthew we’re told, “Not one of them will fall to the ground apart from your Father.” Think about that. If the bird dies on the branch, and the bird has no immortal soul, and is from that moment only inanimate matter, already basically dust, how can it be “with” God as it’s falling? And not in some abstract all-of-creation sense but in the very way that we are with Him, the explicit point of the verse: the line right before it is “fear not them which kill the body, but are not able to kill the soul.” If sparrows lack souls, if the logos liveth not in them, Jesus isn’t making any sense in Matthew 10:28-29.
What changed and interrupted the ancient and deeply human appreciation of our kinship with besouled animals? Sullivan’s answer is René Descartes. The modern depreciation of animals, Sullivan writes,
proceeds, with the rest of the Enlightenment, from the mind of René Descartes, whose take on animals was vividly (and approvingly) paraphrased by the French philosopher Nicolas Malebranche: they “eat without pleasure, cry without pain, grow without knowing it; they desire nothing, fear nothing, know nothing.” Descartes’ term for them was automata—windup toys, like the Renaissance protorobots he’d seen as a boy in the gardens at Saint-Germain-en-Laye, “hydraulic statues” that moved and made music and even appeared to speak as they sprinkled the plants.
Too easy, however, is the move to say that the modern comprehension of the difference between animal and human proceeds from a mechanistic view of animals. We live at a time of the animal rights movement. Around the world, societies exist and thrive whose mission is to prevent cruelty toward and to protect animals. Yes, factory farms treat chickens and pigs as organic mechanisms for the production of meat, but these farms co-exist with active and quite successful movements calling for humane standards in food production. Whatever the power of Cartesian mechanics, its success is at odds with the persistence of the religious, ancient solidarity, and also deeply modern sympathy between human and animal.
A more meaningful account of the modern attitude towards animals might be found in Spinoza. Spinoza, as Sullivan quotes him, recognizes that animals feel in ways that Descartes did not. As do animal rights activists, Spinoza admits what is obvious: that animals feel pain, show emotion, and have desires. And yet, Spinoza maintains a distinction between human and animal—one grounded not in emotion or feeling, but in human nature. In his Ethics, he writes:
Hence it follows that the emotions of the animals which are called irrational…only differ from man’s emotions to the extent that brute nature differs from human nature. Horse and man are alike carried away by the desire of procreation, but the desire of the former is equine, the desire of the latter is human…Thus, although each individual lives content and rejoices in that nature belonging to him wherein he has his being, yet the life, wherein each is content and rejoices, is nothing else but the idea, or soul, of the said individual…It follows from the foregoing proposition that there is no small difference between the joy which actuates, say, a drunkard, and the joy possessed by a philosopher.
Spinoza argues against the law prohibiting slaughter of animals—it is “founded rather on vain superstition and womanish pity than on sound reason”—because humans are more powerful than animals. Here is how he defends the slaughter of animals:
The rational quest of what is useful to us further teaches us the necessity of associating ourselves with our fellow men, but not with beasts, or things, whose nature is different from our own; we have the same rights in respect to them as they have in respect to us. Nay, as everyone’s right is defined by his virtue, or power, men have far greater rights over beasts than beasts have over men. Still I do not deny that beasts feel: what I deny is that we may not consult our own advantage and use them as we please, treating them in the way which best suits us; for their nature is not like ours.
Spinoza’s point is quite simple: Of course animals feel and of course they are intelligent. Who could doubt such a thing? But they are not human. That is clear too. While we humans may care for and even love our pets, we recognize the difference between a dog and a human. And we will, in the end, associate more with our fellow humans than with dogs and porpoises. Finally, we humans will use animals when they serve our purposes. And this is ok, because have the power to do so.
Is Spinoza arguing that might makes right? Surely not in the realm of law amongst fellow humans. But he is insisting that we recognize that for us humans, there is something about being human that is different and, even, higher and more important. Spinoza couches his argument in the language of natural right, but what he is saying is that we must recognize that there are important differences between animals and humans.
At a time that values equality over what Friedrich Nietzsche called the “pathos of difference,” the valuation of human beings over animals is ever more in doubt. This comes home clearly in a story told recently by General Stanley McChrystal, about a soldier who expressed sympathy for some dogs killed in a raid in Iraq. McChrystal responded, severely: “"Seven enemy were killed on that target last night. Seven humans. Are you telling me you're more concerned about the dog than the people that died? The car fell silent again. "Hey listen," I said. "Don't lose your humanity in this thing."” Many, no doubt, are more concerned, or at least are equally concerned, about the deaths of animals as they are about the deaths of humans. There is ever-increasing discomfort about McChrystal’s common sense affirmation of Spinoza’s claim that human beings simply are of more worth than animals.
The distinctions upon which the moral sense of human distinction is based are foundering. For DeWaal and Sullivan, the danger today is that we continue to insist on differences between animals and humans—differences that we don’t fully understand. The consequences of their openness to the humanization of animals, however, is undoubtedly the animalization of humans. The danger that we humans lose sight of what distinguishes us from animals is much more significant than the possibility that we underestimate animal intelligence.
I fully agree with DeWaal and Sullivan that there is a symphony of intelligence in the world, much of it not human. And yes, we should have proper respect for our ignorance. But all the experiments in the world do little to alter the basic facts, that no matter how intelligent and feeling and even conscious animals may be, humans and animals are different.
What is the quality of that difference? It is difficult to say and may never be fully articulated in propositional form. On one level it is this: Simply to live, as do plants or animals, does not constitute a human life. In other words, human life is not simply about living. Nor is it about doing tasks or even being conscious of ourselves as humans. It is about living meaningfully. There may, of course, be some animals that can create worlds of meaning—worlds that we have not yet discovered. But their worlds are not the worlds to which we humans aspire.
Over two millennia ago, Sophocles, in his “Ode to Man,” named man Deinon, a Greek word that connotes both greatness and horror, that which is so extraordinary as to be at once terrifying and beautiful. Man, Sophocles tells us, can travel over water and tame animals, using them to plough fields. He can invent speech, and institute governments that bring humans together to form lasting institutions. As an inventor and maker of his world, this wonder that is man terrifyingly carries the seeds of his destruction. As he invents and comes to control his world, he threatens to extinguish the mystery of his existence, that part of man that man himself does not control. As the chorus sings: “Always overcoming all ways, man loses his way and comes to nothing.” If man so tames the earth as to free himself from uncertainty, what then is left of human being?
Sophocles knew that man could be a terror; but he also glorified the wonder that man is. He knew that what separates us humans from animals is our capacity to alter the earth and our natural environment. “The human artifice of the world,” Arendt writes, “separates human existence from all mere animal environment…” Not only by building houses and erecting dams—animals can do those things and more—but also by telling stories and building political communities that give to man a humanly created world in which he lives. If all we did as humans was live or build things on earth, we would not be human.
To be human means that we can destroy all living matter on the Earth. We can even today destroy the earth itself. Whether we do so or not, it now means that to live on Earth today is a “Choice” that we make, not a matter of fate or chance. Our Earth, although we did not create it, is now something we humans can decide to sustain or destroy. In this sense, it is a human creation. No other animal has such a potential or such a responsibility.
There is a deep desire today to flee from that awesome and increasingly unbearable human responsibility. We flee, therefore, our humanity and take solace in the view that we are just one amongst the many animals in the world. We see this reductionism above all in human rights discourse. One core demand of human rights—that men and women have a right to live and not be killed—brought about a shift in the idea of humanity from logos to life. The rise of a politics of life—the political demand that governments limit freedoms and regulate populations in order to protect and facilitate their citizens’ ability to live in comfort—has pushed the animality, the “life,” of human beings to the center of political and ethical activity. In embracing a politics of life over a politics of the meaningful life, human rights rejects the distinctive dignity of human rationality and works to reduce humanity to its animality.
Hannah Arendt saw human rights as dangerous precisely because they risked confusing the meaning of human worldliness with the existence of mere animal life. For Arendt, human beings are the beings who build and live in a political world, by which she means the stories, institutions, and achievements that mark the glory and agony of humanity. To be human, she insists, is more than simply living, laboring, working, acting, and thinking. It is to do all of these activities in such a way as to create, together, a common life amongst a plurality of persons.
I fear that the interest in animal consciousness today is less a result of scientific proof that animals are human than it is an increasing discomfort with the world we humans have built. A first step in responding to such discomfort, however, is a reaffirmation of our humanity and our human responsibility. There is no better way to begin that process than in engaging with a very human response to the question of our animality. Towards that end, I commend to you “One of Us,” by John Jeremiah Sullivan.
Golden Dawn, the far-Right fascist party in Greece continues to grow in popularity and violence, according to the Wall Street Journal. Last week the Journal reports:
In a rundown, immigrant-filled neighborhood here, Ilias Panagiotaros, a member of Parliament from Greece's far-right Golden Dawn party, used a megaphone Friday night to exhort an angry crowd to "fight against foreign invaders."
A family watching from a second-floor balcony scrambled for cover as demonstrators hurled bottles and stones at them. "We're going to spill your blood, you Albanian pigs," a man in the flag-waving throng screamed.
Hundreds of protesters marched through the narrow streets—some spraying nationalist graffiti on building facades, others shouting obscene taunts at immigrants. Mr. Panagiotaros, a heavyset man with a shaved head, led them in a resounding chant: "Foreigners out. Greece for the Greeks."
Now this weekend the Washington Post has a follow up (as Walter Russell Mead writes). The Post describes a Greek army surplus store that proudly displays a sticker that carries a favorite party slogan: “Get the Stench out of Greece.” The Post continues:
By “stench,” the Golden Dawn — which won its first-ever seats in the Greek Parliament this spring and whose popularity has soared ever since — means immigrants, broadly defined as anyone not of Greek ancestry. In the country at the epicenter of Europe’s debt crisis, and where poverty and unemployment are spiking, the surplus shop doubles as one of the party’s dozens of new “help bureaus.” Hundreds of calls a day come in from desperate families seeking food, clothing and jobs, all of which the Golden Dawn is endeavoring to provide, with one major caveat: for Greeks only.
Attacks have not stopped at foreigners. One Golden Dawn legislator slapped a left-wing female politician on national television. Party supporters have attempted to shut down performances of progressive theater. Activists see the party’s hand behind three recent beatings of gay men. The Golden Dawn has also begun engaging left-wing anarchy groups in street battles — more evidence, observers say, of a societal breakdown that some here fear could slide into a civil war if Greece is forced out of the euro and into an even deeper crisis.
But perhaps more worrisome, critics say, are signs that the Golden Dawn is establishing itself as an alternative authority in a country crippled by the harsh austerity imposed by its international lenders. It has set up its own “pure” blood bank, providing and accepting donations to and from Greeks only, in a nation of 11 million that is also home to roughly 1.5 million refugees and migrants, many of them from the Middle East, South Asia and Africa. As the party attempts to place a swelling number of unemployed in jobs, its officials say they have persuaded a major restaurant chain to begin replacing immigrants with Greek workers.
The Arendt Center is keeping a close eye on Golden Dawn. The increasing popularity of the party in Greece, which currently polls at over 20% of the Greek population, is a reminder that real economic crises rarely limit themselves to economic upheaval. Many names and words will be bandied about in and with regard to Greece. People will talk about fascism, racism, and totalitarianism. The point is to keep our eyes open to what is happening, which at this point is ugly political nativism along with racialized violence that is gaining enough popular appeal so that it is not being confronted and stopped by legal authorities. It is partly a result of racism, but also a consequence of the utter loss of power and legitimacy on behalf of the Greek elite and the Greek government that has abandoned Greek self-rule to a technocratic European elite. When people feel totally helpless and out of control, as Greeks do today, they will unfortunately seek out scapegoats and victims. The last thing they want to admit is that it is the Greek people themselves and their leaders who are to blame for their predicament.
One key step in any move towards totalitarianism is the erasure of legal citizenship or legal protections for a defined minority. Legal and illegal immigrants are already vulnerable groups even in good times. The danger is that immigrants lose even the basic legal protections and rights that they currently have and, once they do, become superfluous people, the kind of people who simply can be rounded up, imprisoned, expelled, or killed without any legal notice or response—or even according to the law. That of course is not happening in Greece. Let's hope it does not.
The Wall Street Journal ran an interview this week with Luke Muehlhauser, the Executive Director of the Singularity Institute. The Journal asked: Will Artificial Intelligence Make us Obsolete? Muehlhauser's answer was, well yes. In his words:
Cognitive science has discovered that everything the human mind does is done by information processing and machines can do information processing too.
The first statement is clearly false, or at least depends on a strangely mixed up idea of "information processing." The old determinist canard that humans are simply complex machines has not been proven or discovered by cognitive science. And even if humans do process billions upon billions of bits of information it is not at all clear that such a humanly fallible process is reproducible. That is not the claim that cognitive science can make.
But cognitive science can claim that machines can be built that act in ways that are so like humans as to be almost nearly indistinguishable from them. Or, they can even be better than humans in doing many quintessentially human tasks. So machines can not only beat humans at chess, they can make moves that seem like moves only a human could have made, as Gary Kasparov learned to his dismay in the second game of his rematch with Deep Blue. Machines can create paintings that appear to be fully creative, as does Aaron, the painting machine created by artist and computer scientist Harold Cohen. And machines can increasingly make ethical decisions in warfare, as the robo-ethicist Ron Arkin has argued—decisions that are more humane than those made by human warriors.
Too much of the debate over artificial intelligence is caught up in the technical and really irrelevant question of whether machines can fully replicate human beings. The point is that if machines act "as if" they are human, or if they are capable of doing what humans do better than humans, we will gradually and continually allow machines to take over more and more of the basic human activities that make up our world. Already computers make most of the trades on Wall Street and computers are increasingly used in making medical diagnoses. Computers are being used to educate our children and write news stories. Caregivers for the elderly are being replaced by robotic companions. And David Levy, artificial intelligence researcher at the University of Maastricht in the Netherlands, argues that we will be marrying robots in the near future. It is not that these robotic lovers or artificial artists are human, but that they love and paint in ways that do or will soon pass the Turing test: they will be impossible to distinguish from human works.
Undoubtedly one reason machines are acting more human is that humans themselves are acting less so. As we interact more and more with machines, we begin to act predictably, repetitively, and less surprisingly. There is a convergence at foot, and it is the dehumanization of human beings as much as the humanization of robots that should be worrying us.
Two articles in the Wall Street Journal and the New York Times this weekend show the grave threats to two great institutions, both of which I care deeply about.
The Times has a story on the threatened cuts looming over the University of California and the State University of California system.
Class sizes have increased, courses have been cut and tuition has been raised - repeatedly. Fewer colleges are offering summer classes. Administrators rely increasingly on higher tuition from out-of-staters. And there are signs it could get worse: If a tax increase proposed by Gov. Jerry Brown is not approved this year, officials say they will be forced to consider draconian cuts like eliminating entire schools or programs.
To get a sense of the problem, just consider this:
While there are more students than ever, the number of academic advisers has dropped to 300, from 500 a few years ago, for more than 18,000 undergraduates. Courses that used to require four writing assignments now demand half that because professors have fewer assistants to help them with grading papers, something other campuses have implemented as well.
Meanwhile, the WSJ reports that policemen and firefighters in San Jose, California are being insulted, flipped off, and outright despised. One officer was recently criticized at a supermarket checkout line for buying steaks. A firefighter reports being given the finger while in his truck. This is sad. These are people who are prepared to risk their lives to protect us. They do so for salaries that allow them to live well, but not well enough to actually afford a home in San Jose, where the median house price is over $400k. Are these officers and heroes really the blood-sucking vampires that they are being made out to be?
Clearly the answer is no, and yet the officers do make very rich pensions. As the WSJ reports:
In the current fiscal year ending June 30, San Jose's retirement obligations soared to $245 million, up from $73 million a decade ago, according to the city. For police officers and firefighters who have retired since 2007, the average pension is $95,336, making them among the most generously compensated in the state.
The threat to the California public universities and the animosity to public-safety officers who make up an important part of the middle class are two sides of the same problem. As pension costs soar, governments are taking away middle-class services like education, park playgrounds, and libraries. As middle-class taxpayers see their services cut, they blame those whose middle-class lives they are supporting. We are in for lots of this over the next decade.
The Arendt Center continues to follow the pension crisis because it is another example of the way that facts staring us in the face can simply be denied and ignored by those who don't want to see them. We also are following the pension mess because we care about politics and government. The attack on government today too often takes the form of a rejection of all public activity and the claim that all services and all valuable activities are private, not public.
