One would expect that in order for a specific theory to become valid and undoubtedly accepted, it ought to be based not merely on numerous observations of those who founded it, but also supported by recorded and further investigated real-life examples. Sampson refers back to the Middle Ages when ordinary people were not prepared to go into the fields to investigate or use their own brains to think. That was the time when the authority of an eminent predecessor seemed to outweigh their notion of the world. Consequently many fanciful tales continued to be repeated and believed as Sampson believes to be the case with the nativist story, with which his book disagrees. “The “Language Instinct” Debate” confutes the established nativist theory, which claims human beings possess complex features of linguistic structure encoded in our genes like a bird’s nest-building or a dog’s habit of burying bones. Since Sampson perceives language as a cultural creation which may be learnt during our lifetimes depending on the culture one is born into, he is convinced no one is innately predisposed. Human’s natural curiosity along with a propensity to come up with new ideas and experiment, force nature to willingly or unwillingly answer the questions raised. Experiments leave us only with prosperous ideas and winnow away the mistaken ones, resulting in unsteady but cumulative growth of human knowledge. The example supporting his theory is taken out of Willy Russell’s play “Educating Rita”, a story about a naive and ignorant young Liverpool hairdresser, who is determined to improve her unsatisfying life by learning. Slowly and uncertainly Rita climbs intellectually proving that mankind is capable of learning anything, starting from scratch. This precise capability defies the belief of built-in knowledge in that it allows us to adapt to different circumstances which according to Sampson is the 1 »THE »Language Instinct« DEBATE« Maja Juričinec crucial difference between us and the animals. Nativists on the other hand defend their point of view by claiming that our richer instinctive knowledge base lets us do greater variety of things. Defying these assumptions Samson argues that nor Rita or our ancestors, who began the longest process of cultural development of which we benefit today, knew nothing to start with. We as present-day descendants have not inherited knowledge, but only the ability to gain knowledge. While nativism is based on the idea of knowledge being biologically built-in or native to human mind, Sampson as an empiricist sees human knowledge as a cultural product – the outcome of many generations of trail-and-error experimentation. The first languages were those that changed the process of getting knowledge from an individual to a communal activity, therefore they are considered as the most significant cultural innovations. A newborn baby gains its knowledge in the same way as our first human ancestors did: through their own testing of their own guesses. The advantage of the succeeding generations is that they do not have to go back to the start and go through the same painful knowledgewinning as our prior generations had to. Their process of guessing and experimentation can continue where there elders left off. To the contrary, nativists believe that human beings have biologically inherited knowledge base along with its biologically inherited coding system. They are convinced that facts about human language such as its structure and the manner in which children acquire their mother tongue offer the only reasonable explanation to an unprejudiced eye that knowledge cannot be perceived otherwise than biologically inherited. They support their arguments by saying that children would not be as good at learning the language if they had to learn it from scratch. Nativists, who examined various languages of the world claim to have found such structural similarities between them which cannot be ascribed as cultural achievement. Sampson calls the movement of “linguistic nativism” a revival, for nativistic way of thinking started long ago with its beginner Plato who was convinced that we have immortal souls that remembered things from a 2 »THE »Language Instinct« DEBATE« Maja Juričinec former and more perfect life than this one. According to that belief learning is just a recollection. A French thinker of the 17th century, René Descartes, had a more Christian perspective about the extent of our innate knowledge saying that the ideas present in the mind of a child were put there by God himself. The experience after birth is merely answering the question whether the possible propositions are either “true” or “false”. Despite the different approaches to the similar idea, they both agreed that a newborn child is like a very learned man who is asleep, meaning that the knowledge is in there somewhere, but it needs awakening before it is available for use. As a representative of an opposite point of view called empiricism, Sampson mentions Descartes’ English contemporary John Locke, who argued that knowledge is generated by experience. The fact that Locke’s view prevailed as the default one for almost 300 years has probably much to do with his liberal theory of politics which became the accepted political ideal in all English speaking countries. Empiricism and liberal politics share the same idea that where authoritative knowledge is not given in advance, the freedom to experiment is necessary. The man who initiated linguistic nativism was Noam Chomsky now followed by Steven Pinker and other currently active nativists, who in order to backup their own standpoints rely heavily on Chomsky’s writings and his arguments for nativism. Long before Chomsky with his style of analysing language came along the scientific study of language was seen as a branch of social anthropology. The duty of the ones studying the intricate grammatical and phonetic detail found in any human language was to emphasize the amazing diversity of languages which did not originate from a common ancestor language. Chomsky on the other hand thought quite the opposite: he focused on what languages have in common. According to Chomsky, the great amount of encountered similarities (also among languages that have developed separately) can only be explained in terms of innate linguistic 3 »THE »Language Instinct« DEBATE« Maja Juričinec knowledge. However, he believes that the ability to acquire language in spite of its innateness is much greater before the puberty. Moreover, in his opinion grammar grows in one’s mind the same as teeth grow in one’s mouth. Sampson objects to this saying that if this were true, we would expect everyone to grow up speaking the same language, but we do not. “A newborn English child, brought up in a Chinese environment by Chinese-speaking foster parents, will become a fluent Chinese and not a fluent English speaker (and vice versa).” [Sampson 9] Chomsky considers these differences between languages as superficial details claiming that underlying structural principles are common to all the languages on Earth. As biology prescribes that we shall speak language it also leaves some matters open, which have to be learned by experience after a child is born. Some sceptics object to Chomsky’s usage of the word knowledge. Their definition of having knowledge of something means that one is able to answer questions on it. Therefore, Chomsky’s definition of the human ability to assemble words into meaningful sentences without being aware of the rules they are following is called “tacit knowledge”. Many of those who failed to understand Chomsky’s message have argued against him, but have eventually lost the linguistic battle and nativism remained as the prevailing scientific study of language. Later, in the Margaret Thatcher’s years when Chomsky was fully occupied by his own politics one heard less and less of him and consequently of linguistic nativism. Soon, the new generation of linguistic nativists has won the readers with their much more appealing manner of writing supported by everyday examples. Outrunning numerous nativists like Derek Bickerton, Michael LaBarbera, Ray Jackendoff and many others was Chomsky’s younger Canadian colleague Steven Pinker with his book in 1994 called “The Language Instinct”. Pinker’s fascinating language study is assembled into a pattern designed to convince a new generation that we speak because of the inherited “language instinct”. 4 »THE »Language Instinct« DEBATE« Maja Juričinec Even though Sampson gives Pinker the credit for a well written and fully researched book, he suggests that the conclusions drawn from the research are quite wrong, for according to Sampson there is no such thing as a human language instinct. To make their writings more valid recent nativists include plenty of footnotes referring to Chomsky’s works as if they were established scientific findings from the past. John Locke being the first person in the modern world arguing against innate knowledge, Sampson adopted his point of view on human nature. However, “the best individual guide to the general nature of human intellectual activity”, as Sampson names him, is a philosopher Sir Karl Popper. The latter was convinced that true science was all about making risky guesses about various matters and then testing these guesses to obtain at least the provisional objective results that may sooner or later be refuted. Based on guessing and testing assumption Popper sees the newborn baby as having innate expectations which generate different hypothesis about the external world. Through trial and error principle child becomes aware of guesses that work, consequently the structure of knowledge the child posses elaborates increasingly. One of my favourite sentences in this book was the one in which Sampson describes a child as a little research scientist full of energetic research ideas that needs to be tried out. Since progress comes only through making mistakes, errors are not things to be avoided, but things that enlighten us so we can profit from them. This is basically the same aspect that we learned during our course of didactics of English where we said that mistakes are allowed and accepted, because they are believed to encourage the child’s progress. 5 »THE »Language Instinct« DEBATE« Maja Juričinec SUMMARY OF THE SECOND CHAPTER: “The Original Arguments for a Language Instinct” We know for a fact that no child speaks a language at birth. By being raised in any speech community, children without physical disabilities become competent users of the language spoken within their society. Nativists and empiricists have divergent aspects of human language and the cognitive achievements, which depend on language. While the former advocate that these are products of biology, the latter perceive language almost as a wholly cultural product. None of the two opponents confute that human beings posses some innate abilities. The task of learning and grown up human’s cognitive world depends in some respect on his experience. Since Chomsky does not disregard other views on language as logically coherent, Sampson refutes Chomsky’s theory of innate knowledge of language by responding to each of his seven postulates. Chomsky’s premisses 1 Speed of acquisition In his first postulate Chomsky argues that the speed of language acquisition is faster than one would expect considering the complexity of language system and also faster than the acquisition of knowledge of physics. Sampson argues this belief based on the fact that it takes approximately two years before children master the main grammatical structures of their mother tongue. So the question arises: how long should a period of time for acquiring language be before Chomsky would no longer see the acquisition as “remarkably fast”. One of the possible reasons for the success of Chomsky’s explanation might be the fact that adults tend to become emotional when it comes to small children and praise their every rate of progress. It seems like Chomsky does not 6 »THE »Language Instinct« DEBATE« Maja Juričinec acknowledge the difference between the “tacit” and the “explicit knowledge” of an individual. “Tacit knowledge” enables us to appropriately conform to our linguistic environment, while “explicit knowledge” means we are consciously aware of the structure of a language and this one is certainly not acquired universally or rapidly. Therefore, if we are to compare the speed of language acquisition with the knowledge of physics, we are bound to compare them only on the “tacit knowledge” level, for who can say that abilities as pouring the liquid without spilling it or succeeding throwing a ball roughly where we want it to go require more time to acquire than the ability to speak. In order to perform these physical activities one has to move from observation to some tacit grasp of general principles of physics. The author believes that the two bodies of knowledge can be compared only if they are equal or at least close to equal. So to label grammar “as complex as” atomic physics it would be as meaningless as the statement that the novel War and Peace is twice long as the River Nile. 2 Age dependence Chomsky and other linguistic nativists differ between the terms language acquisition and learning, the former term being the process by which someone becomes a competent user of his mother tongue. They believe that human ability to acquire either a first or a second language diminishes sharply by puberty or somewhat earlier. Empiricists on the other hand do not distinguish between the two expressions; as far as they are concerned everything is learned. The results of empirical researches on factors affecting secondlanguage learning successfully refute Chomsky’s claim about agedependence. As adults can learn a second language relatively easily and rapidly if they see the task as worthwhile, the children whose motivation to study a foreign language is poor, will absorb very little and accordingly achieve far less than a native mastery. The most commonly discussed example is the case of “Genie”, the daughter of an insane father who kept her in isolation from human interaction until the authorities discovered her 7 »THE »Language Instinct« DEBATE« Maja Juričinec at the age of 13. Susan Curtiss, who documented Genie’s progress, saw her as a case in which language acquisition was possible after the “critical period”. Genie’s language-learning progress as well as the development of her social skills was not as successful as they could be if she had not suffered great emotional damage caused by deprivation of normal social stimulation. These emotional scars are also evident in Genie’s retreat from her progress when the funding for research on her ran out and she had to move from one bad foster home to another, when she refused to say a word. Various papers published years later, long after Curtiss was observing Genie were much more supportive of nativism, but since there was no new data, these responses do not count as valid. Eric Lennenberg shared his view of language acquisition with Chomsky, whose findings could probably also apply to learning in general. Lennenberg implied that there are probably numerous tasks and skills, apart from language acquisition, that have no age limitation. Sampson agrees with Lennenberg if he meant that one has to; for example, develop the physical strength in order to acquire skill at archery. As far as intellectual tasks are concerned Jerome Bruner states: “Any subject can be taught effectively in some intellectually honest form to any child at any stage of development.” [Sampson 42] 3 Poverty of data Sampson examines the issue of the real-life evidence, which he calls the “poverty-of-data” argument. Nativists believe that people must be born knowing much of the structure of language for children accomplish to master some of the structures of their mother tongue they never hear in their elders’ usage. Sampson tries to prove that everyday linguistic experience is far richer than the nativists assume. Amongst Chomsky’s attempts to support his belief about language innateness is the one in which he claims that even though the amount of exposure to language during child’s acquisition period is quantitatively 8 »THE »Language Instinct« DEBATE« Maja Juričinec meagre and qualitatively degenerate, the child is capable of deriving general rules about the structure of their first language. Researches on the nature of speech addressed to children indicate that the quality of the so called Motherese is far better than any of the nativists supposed. Since the speech of the child’s elders includes “defective sentences” as well as accurate utterances, nativists reject the theory of parents being ideal language teachers. They believe that a child lacking innate linguistic knowledge would be susceptible to those ungrammatical utterances. Virginia Valiant perceives Motherese as ungrammatical only in a sense of standard written English, but at that stage a child is learning to speak English and not write it; therefore informal spoken sentences beginning with a verb are acceptable and also grammatical in a spoken sense (e.g. “Want your lunch now?”). In arguing against Chomsky, the author takes Chomsky's much used example of English speaking children determining how to ask yes/no questions. He is seeking to show that Chomsky is being dishonest in his analysis by not verifying the data. By investigating the grammar of yes/no questions in English Chomsky came up with two alternative hypotheses that a child might try: 1.) “operate on the first finite verb”, 2.) “operate on the finite verb of the main clause”. Sampson refutes the first one saying that it violates the “structuredependence” universal adding: “The only sentences which reveal the falsity of (1) are yes/no questions formed from statements containing a subordinate clause which precedes the main verb.” [Sampson 45] Although hypothesis (2) proves to be correct, there are still some yes/no questions that fail to distinguish between the two hypotheses. According to Sampson these are simple statements along with the complex ones in which the main verb precedes all the possible subordinate clauses. A child working out how to make a yes/no question in English has to work out that if any verb is to be moved it has to be the verb in the main 9 »THE »Language Instinct« DEBATE« Maja Juričinec clause and not just the first verb encountered in the sentence. In order to work this out, a child would have to distinguish between verbs and other words and also between main verbs and auxiliary verbs as well as knowing the structure of the phrases in the sentence. Chomsky's claim is that a child determines the rule of yes/no question formation even before it may encounter such questions in the language it hears. Sampson argues that such sentences are indeed present in the language that children hear. The point that the author is trying to prove is that all children hear this crucial form of yes/no question before they determine the yes/no question formation rule. Later in his book Sampson introduces findings of Betty Hart and Todd Risley’s research on how much wording children are typically exposed to in the early years indicating that it considerably depends on social class. The most linguistically deprived three-year-olds are those from “families on welfare” for they might have heard “only” 10 million words, while for children from working-class families the figure would be around 20 million words. The most “fortunate” seem to be children raised in a professional households, whose total exposure is estimated to be 30 million words by the age of three. Based on experience people often begin to use a new word after encountering it just once or a handful of times, so Sampson sees no reason why learning a new grammatical construction from experience should require a far greater exposure than learning a new word. 4 Convergence among grammars The fourth argument the book deals with is the notion that children of varying levels of intelligence and different exposure to language inputs, converge on the same grammar, meaning that they all acquire essentially the same language that their elders speak and never fail the task. According to Sampson, Chomsky has at one point permitted the possibility that educated people might be better at mastering their mother tongue (p.50). However, individuals with lower intelligence do 10 »THE »Language Instinct« DEBATE« Maja Juričinec acquire quite a lot of language skills for their motive to learn is to participate in society’s communicative activities. Chomsky’s second argument claims that even though different children are exposed to different finite samples of the language, they all end up acquiring near-identical grammars. Since people give different grammatical judgments in response to the same data, Sampson believes that people do not actually converge on the same grammar as Chomsky proposes. The book refers to Labov's investigation of individuals’ grammars, where respondents varied in their judgments about the grammaticality of presented sentences. All 24 subjects asked to judge a word sequence ”Every one of the boys didn’t go there.” understood oral and written the instructions, which they were given concerning the test. It is hard to see how they could all have the same understanding of what was said to them unless they had pretty much the same grammars. In Sampson’s opinion the only thing individuals’ differing judgments show is that what is being tested is not the individual's competence but their performance. The fact that there is a variation in the reported judgments does not in fact constitute the argument against convergence among grammars – it is not a test of grammars but rather a test of performance. 5 Language universals Sampson is convinced that universal aspects of human languages speak in favour of empiricists supporting their view of human nature. Chomsky himself claimed in 1975 that an innatist hypothesis is, in terms of violation of language universals, a refutable one. Sampson is not rejecting Chomsky’s claim that human languages all share significant structural properties, maybe not necessarily all of those that Chomsky and the other nativists have claimed, yet he merely believes there is a better explanation to it than the hypothesis of innate language knowledge. According to the languages being investigated, Chomsky believes that human languages all share certain structural properties. One could 11 »THE »Language Instinct« DEBATE« Maja Juričinec easily accept that, but before we are satisfied with Chomsky’s offered theory we should take into consideration all possible explanations. One of the language universals is the tree structure in grammar. Sentences consist of words grouped into phrases and clauses nesting inside one another. Chomsky implied that tree structuring in grammar is not a logical necessity, but an empirical finding not realizing that he was the first who classified different types of grammatical system with the help of his elaborated mathematical scheme. Popper and Sampson perceive the universality of tree structuring as a proof that languages are systems developed by human being gradually the same as every other knowledge is. No one doubts in tree structure of all languages. What Sampson demonstrates is that syntactic structure is not an argument for the language organ. He follows a parable about two watchmakers by Herbert Simon originally applied to economics where the only, though essential difference between the two kinds of watches is that one are hierarchically structured while the others are not. The main point of the parable is that complex entities produced by an undirected process will result in tree structuring. He namely believes that building things up out of smaller components is the most efficient way of achieving that complexity. Darwin explained that in terms of evolutionary process, meaning that organisms of increasing complexity would endure through time. As in evolutionary process where simpler cells are gradually replaced by more complex ones which later develop in even more complex organisms, the structure of human language works in approximately the same tree-shaped structuring. In Derek Bickerton’s opinion we can study the way language was first developed by our distant forefathers by observing one-word sentences of a child at 21 months like: “Get.” “Apple.” or “Wash” “Baby”. When these sentences prove to work, a grammatical rule would come to existence and the two separate words would usually be upgraded into twoword utterances: “Get apple.” “Wash baby.”. If we look at both of the twoword sentences we can assume that our ancestors would begin to work according to “verb” and ”noun” classification. The main point is that if gradual guess-and-test development of languages is correct than the 12 »THE »Language Instinct« DEBATE« Maja Juričinec language grammar will be hierarchically structured and this is the same way in which we must build up our understanding of our mother tongue. So it is no surprise that today’s children try to apply tree structure on languages they learn; previous generations have done the same. For being able to draw the correlation between the evolutionary development and hierarchical structure, we ought to thank Herbert Simon. Nativists’ theory of language universals does not contain a concrete description of an individual language. It does not tell us things like with which letter a specific word begins or ends or that an adjective universally goes before the noun and so on. This is because properties of this sort are not universal among all human languages – French for example uses quite the opposite rule for adjectives. Since Sampson sees languages as products of cultural development reconstructed by individuals through a Popperian process of guessing and testing, properties of languages that coincide occur by chance, or through the mechanisms of cultural transmission. The author says that if human beings had innate knowledge of language as Chomsky predicted, a baby separated at birth from its biological parents would be influenced by the same language its biological parents speak, yet we know that a child reconstructs the language it hears. Central to Pinker’s case for nativism are tree structuring and structure dependence; though the very first study he discusses are Joseph Greenbergs’s universals of word order of languages from diverse areas of the world. Sampson however thinks that Greenberg’s findings do little to support the nativist case apart from providing the readers fond of nativist theory with concrete examples. Nativists discuss different types of universals in their books. Pinker, for example, writes plenty about Greenberg’s universal claiming that subjects precede object in almost all languages. If we think of the subject as the element with which the verb agrees, that cannot be count as a language universal, because we know languages in which verbs do not inflect at all. Take for example an English sentence: “John was killed”. Another such idea on which Pinker spends 13 »THE »Language Instinct« DEBATE« Maja Juričinec his time on is that human beings cannot cope with multiple central embeddings, such as “The malt that the rat that the cat killed ate lay in the house”. [Sampson 160] Sampson argues that by saying that one can easily stumble upon multiple central embeddings in writings for adults (The Times) and children as well as in student essays and spoken utterances, moreover they are understandable. To support his argument he quotes a sentence from a published academic article about linguistics written by a Canadian: “The only thing that the words that can lose –d have in common is, apparently, that they are all quite common words.” [Sampson 160] Bickerton’s scrutinizing of various human languages led him to conclude that all words fall into hierarchal relationships, as for example dog is the “superordinate” term for spaniel. He suggests that in human languages all words have superordinates. Sampson, however, does not agree with Bickerton claiming that the superordinate term for carpet does not exist, although some might perceive a carpet as a piece of furniture. In addition, he challenges the reader to find his own example of a word that has no superordinate. Sampson sums up the discussion about language universals using the following words: "Yes, there are universal features in human languages, but what they mainly show is that human beings have to learn their mother tongues from scratch rather than having knowledge of language innate in their minds." [Sampson 166] 14 »THE »Language Instinct« DEBATE« Maja Juričinec 6 Non-linguistic analogies The number system is in Chomsky’s opinion common and unique to all humans. He perceives the essence of the number system as the concept of adding one, indefinitely. As far as Sampson is concerned these claims are false. Infinity in the way that Chomsky describes it is a mathematical conception, which is usually too abstract for an average person to comprehend. The author is aware that the modern European number system does not result from our experience of the physical world. Since the concept of infinity was developed in the mid-nineteenth century, Sampson implies a question of whether “…our own ancestor until a few centuries ago were less than fully human with respect to their cognitive equipment?” (p. 53). Accordingly, he perceives the notion of infinity as a case of cultural development. 7 Species-specificity Ancient observations show that only human beings possess language. This suggests that there is some genetically encoded property of the species that is essential to the acquisition of language. Regarding the evolutionary process and the presumption that our first remote ancestors were apes, a number attempts have been made in teaching language or language-like systems (sign language, a series of colored plastic tokens etc.) to chimpanzees (Vicky, Washoe, Sarah, Lana etc.) and other apes. Some success has been achieved, but Chomsky describes these experiments as unsuccessful, claiming that nevertheless the access to language experience was comparable to those available to human children the apes did not surpass the language mastery of a two-year-old child. It seems as if the results gained are irrelevant to nativist case. Studies have shown that the adult human ability to speak may besides the cognitive development of the brains be also ascribed to human vocal tract differing in shape from those of other primates. Having the shape of vocal tract as we do enables us to speak, but the other hand one can choke to death on food lodged in the windpipe. 15 »THE »Language Instinct« DEBATE« Maja Juričinec CONCLUSION »The »Language Instinct« Debate« systematically lists all the separate strands of argument that Chomsky uses in his various writings to infer innate knowledge/ideas from observable facts about language. Sampson represents the nativists' positions fairly and even finds himself in agreement with some of their less central ideas. I find criticisms of “speed of acquisition”, “age-dependence” and “poverty of data” persuasive, but it also depends on one’s viewpoint. If a teacher of English would try to oppose the nativist theory he/she could say that a foreign language learner interested in learning English is a fast one, if it took him/her less than two years to master the basic structures of English grammar along with quite a great amount of English vocabulary. However, one could recognize this rapid progress of learning as a language universal meaning that the learner has already acquired one language (his/hers mother tongue) from which he can derive the properties of a second language. Anyhow, I find the book worth reading, because it provides a view of how human languages work without appealing to nativist assumptions. It cautions that scientific arguments should be based on reliable data and that linguistics is no exception. Corpus linguistics makes available many tools for finding examples needed in linguistic study, and linguists should use those resources in addition to introspective and experimental data. However, empirical data can answer some questions, but not all of them. It seems to me that both positions are too extreme and absolute, so the correct solution can often be found between two extremes. Perhaps one of the central tasks of linguists is to find the balancing point between these two extremes, where the solution may well lie. 16 »THE »Language Instinct« DEBATE« Maja Juričinec Works cited and referred too: Cowie, Fiona.
