Colorless Green Ideas Sleep Furiously

Linguist, philosopher, and more recently political activist, Noam Chomsky penned the title phrase in the late 1950s. The sentence is grammatically correct, but semantically nonsensical. Some now maintain that many of Chomsky’s early ideas on the innateness of human language are equally nonsensical. Chomsky popularized the idea that language is innate to humans; that somehow and somewhere the minds of human infants contain a mechanism that can make sense of language by applying rules encoded in and activated by our genes. Steven Pinker expanded on Chomsky’s theory by proposing that the mind contains an innate device that encodes a common, universal grammar, which is foundational to all languages across all human societies.

Recently however, this notion has come under increasing criticism. A  growing number of prominent linguistic scholars, including Professor Vyvyan Evans, maintain that Chomsky’s and Pinker’s linguistic models are outdated — that a universal grammar is nothing but a finely-tuned myth. Evans and others maintain that language arises from and is directly embodied in experience.

From the New Scientist:

The ideas of Noam Chomsky, popularised by Steven Pinker, come under fire in Vyvyan Evans’s book The Language Myth: Why language is not an instinct

IS THE way we think about language on the cusp of a revolution? After reading The Language Myth, it certainly looks as if a major shift is in progress, one that will open people’s minds to liberating new ways of thinking about language.

I came away excited. I found that words aren’t so much things that can be limited by a dictionary definition but are encyclopaedic, pointing to sets of concepts. There is the intriguing notion that language will always be less rich than our ideas and there will always be things we cannot quite express. And there is the growing evidence that words are rooted in concepts built out of our bodily experience of living in the world.

Its author, Vyvyan Evans, is a professor of linguistics at Bangor University, UK, and his primary purpose is not so much to map out the revolution (that comes in a sequel) but to prepare you for it by sweeping out old ideas. The book is sure to whip up a storm, because in his sights are key ideas from some of the world’s great thinkers, including philosophers Noam Chomsky and Jerry Fodor.

Ideas about language that have entered the public consciousness are more myth than reality, Evans argues. Bestsellers by Steven Pinker, the Harvard University professor who popularised Chomksy in The Language InstinctHow the Mind Works and The Stuff of Thought, come in for particular criticism. “Science has moved on,” Evans writes. “And to end it all, Pinker is largely wrong, about language and about a number of other things too…”

The commonplace view of “language as instinct” is the myth Evans wants to destroy and he attempts the operation with great verve. The myth comes from the way children effortlessly learn languages just by listening to adults around them, without being aware explicitly of the governing grammatical rules.

This “miracle” of spontaneous learning led Chomsky to argue that grammar is stored in a module of the mind, a “language acquisition device”, waiting to be activated, stage-by-stage, when an infant encounters the jumble of language. The rules behind language are built into our genes.

This innate grammar is not the grammar of a school textbook, but a universal grammar, capable of generating the rules of any of the 7000 or so languages that a child might be exposed to, however different they might appear. In The Language Instinct, Pinker puts it this way: “a Universal Grammar, not reducible to history or cognition, underlies the human language instinct”. The search for that universal grammar has kept linguists busy for half a century.

They may have been chasing a mirage. Evans marshals impressive empirical evidence to take apart different facets of the “language instinct myth”. A key criticism is that the more languages are studied, the more their diversity becomes apparent and an underlying universal grammar less probable.

In a whistle-stop tour, Evans tells stories of languages with a completely free word order, including Jiwarli and Thalanyji from Australia. Then there’s the Inuit language Inuktitut, which builds sentences out of prefixes and suffixes to create giant words like tawakiqutiqarpiit, roughly meaning: “Do you have any tobacco for sale?” And there is the native Canadian language, Straits Salish, which appears not to have nouns or verbs.

An innate language module also looks shaky, says Evans, now scholars have watched languages emerge among communities of deaf people. A sign language is as rich grammatically as a spoken one, but new ones don’t appear fully formed as we might expect if grammar is laid out in our genes. Instead, they gain grammatical richness over several generations.

Now, too, we have detailed studies of how children acquire language. Grammatical sentences don’t start to pop out of their mouths at certain developmental stages, but rather bits and pieces emerge as children learn. At first, they use chunks of particular expressions they hear often, only gradually learning patterns and generalising to a fully fledged grammar. So grammars emerge from use, and the view of “language-as-instinct”, argues Evans, should be replaced by “language-as-use”.

The “innate” view also encounters a deep philosophical problem. If the rules of language are built into our genes, how is it that sentences mean something? How do they connect to our thoughts, concepts and to the outside world?

A solution from the language-as-instinct camp is that there is an internal language of thought called “mentalese”. In The Language Instinct, Pinker explains: “Knowing a language, then, is knowing how to translate mentalese into strings of words.” But philosophers are left arguing over the same question once removed: how does mentalese come to have meaning?

Humanity Becoming “Nicer”

Peter Singer, Professor of Bioethics at Princeton, lends support to Steven Pinker’s recent arguments that our current era is less violent and more peaceful than any previous period of human existence.

[div class=attrib]From Project Syndicate:[end-div]

With daily headlines focusing on war, terrorism, and the abuses of repressive governments, and religious leaders frequently bemoaning declining standards of public and private behavior, it is easy to get the impression that we are witnessing a moral collapse. But I think that we have grounds to be optimistic about the future.

Thirty years ago, I wrote a book called The Expanding Circle, in which I asserted that, historically, the circle of beings to whom we extend moral consideration has widened, first from the tribe to the nation, then to the race or ethnic group, then to all human beings, and, finally, to non-human animals. That, surely, is moral progress.

We might think that evolution leads to the selection of individuals who think only of their own interests, and those of their kin, because genes for such traits would be more likely to spread. But, as I argued then, the development of reason could take us in a different direction.

On the one hand, having a capacity to reason confers an obvious evolutionary advantage, because it makes it possible to solve problems and to plan to avoid dangers, thereby increasing the prospects of survival. Yet, on the other hand, reason is more than a neutral problem-solving tool. It is more like an escalator: once we get on it, we are liable to be taken to places that we never expected to reach. In particular, reason enables us to see that others, previously outside the bounds of our moral view, are like us in relevant respects. Excluding them from the sphere of beings to whom we owe moral consideration can then seem arbitrary, or just plain wrong.

Steven Pinker’s recent book The Better Angels of Our Nature lends weighty support to this view.  Pinker, a professor of psychology at Harvard University, draws on recent research in history, psychology, cognitive science, economics, and sociology to argue that our era is less violent, less cruel, and more peaceful than any previous period of human existence.

The decline in violence holds for families, neighborhoods, tribes, and states. In essence, humans living today are less likely to meet a violent death, or to suffer from violence or cruelty at the hands of others, than their predecessors in any previous century.

Many people will doubt this claim. Some hold a rosy view of the simpler, supposedly more placid lives of tribal hunter-gatherers relative to our own. But examination of skeletons found at archaeological sites suggests that as many as 15% of prehistoric humans met a violent death at the hands of another person. (For comparison, in the first half of the twentieth century, the two world wars caused a death rate in Europe of not much more than 3%.)

Even those tribal peoples extolled by anthropologists as especially “gentle” – for example, the Semai of Malaysia, the Kung of the Kalahari, and the Central Arctic Inuit – turn out to have murder rates that are, relative to population, comparable to Detroit, which has one of the highest murder rates in the United States. In Europe, your chance of being murdered is now less than one-tenth, and in some countries only one-fiftieth, of what it would have been had you lived 500 years ago.

Pinker accepts that reason is an important factor underlying the trends that he describes. In support of this claim, he refers to the “Flynn Effect” – the remarkable finding by the philosopher James Flynn that since IQ tests were first administered, scores have risen considerably. The average IQ is, by definition, 100; but, to achieve that result, raw test results have to be standardized. If the average teenager today took an IQ test in 1910, he or she would score 130, which would be better than 98% of those taking the test then.

It is not easy to attribute this rise to improved education, because the aspects of the tests on which scores have risen the most do not require a good vocabulary, or even mathematical ability, but instead assess powers of abstract reasoning.

Misconceptions of Violence

We live in violent times. Or do we?

Despite the seemingly constant flow of human engineered destruction on our fellow humans, other species and our precious environment some thoughtful analysis — beyond the headlines of cable news — shows that all may not be lost to our violent nature. An insightful interview with psychologist Steven Pinker, author of “How the Mind Works” shows us that contemporary humans are not as bad as we may have thought. His latest book, “The Better Angels of Our Nature: Why Violence Has Declined,” analyzes the basis and history of human violence. Perhaps surprisingly Pinker suggests that we live in remarkably peaceful times, comparatively speaking. Characteristically he backs up his claims with clear historical evidence.

[div class=attrib]From Gareth Cook for Mind Matters:[end-div]

COOK: What would you say is the biggest misconception people have about violence?
PINKER: That we are living in a violent age. The statistics suggest that this may be the most peaceable time in our species’s existence.

COOK: Can you give a sense for how violent life was 500 or 1000 years ago?
PINKER: Statistics aside, accounts of daily life in medieval and early modern Europe reveal a society soaked in blood and gore. Medieval knights—whom today we would call warlords—fought their numerous private wars with a single strategy: kill as many of the opposing knight’s peasants as possible. Religious instruction included prurient descriptions of how the saints of both sexes were tortured and mutilated in ingenious ways. Corpses broken on the wheel, hanging from gibbets, or rotting in iron cages where the sinner had been left to die of exposure and starvation were a common part of the landscape. For entertainment, one could nail a cat to a post and try to head-butt it to death, or watch a political prisoner get drawn and quartered, which is to say partly strangled, disemboweled, and castrated before being decapitated. So many people had their noses cut off in private disputes that medical textbooks had procedures that were alleged to grow them back.

COOK: How has neuroscience contributed to our understanding of violence and its origins?
PINKER: Neuroscientists have long known that aggression in animals is not a unitary phenomenon driven by a single hormone or center. When they stimulate one part of the brain of a cat, it will lunge for the experimenter in a hissing, fangs-out rage; when they stimulate another, it will silently stalk a hallucinatory mouse. Still another circuit primes a male cat for a hostile confrontation with another male. Similar systems for rage, predatory seeking, and male-male aggression may be found in Homo sapiens, together with uniquely human, cognitively-driven  systems of aggression such as political and religious ideologies and moralistic punishment. Today, even the uniquely human systems can be investigated using functional neuroimaging. So neuroscience has given us the crucial starting point in understanding violence, namely that it is not a single thing. And it has helped us to discover biologically realistic taxonomies of the major motives for violence.

COOK: Is the general trend toward less violence going to continue in the future?
PINKER: It depends. In the arena of custom and institutional practices, it’s a good bet. I suspect that violence against women, the criminalization of homosexuality, the use of capital punishment, the callous treatment of animals on farms, corporal punishment of children, and other violent social practices will continue to decline, based on the fact that worldwide moralistic shaming movements in the past (such as those against slavery, whaling, piracy, and punitive torture) have been effective over long stretches of time. I also don’t expect war between developed countries to make a comeback any time soon. But civil wars, terrorist acts, government repression, and genocides in backward parts of the world are simply too capricious to allow predictions. With six billion people in the world, there’s no predicting what some cunning fanatic or narcissistic despot might do.
