R. M. Frank. “Entrenched Conceptual Integration Networks in 19th Century Evolutionary Biology and Comparative-Historical Philology: The Language-Species-Organism Analogy.”

 

Revised Abstract: In recent years the relationship between language change and biological evolution has captured the attention of investigators operating in different disciplines, particularly evolutionary biology, AI and A-Life (Zeimke 2001, Hull 2001), as well as linguistics (Croft 2000; Sinha 1999), with each group often bringing radically different conceptualizations of the object under study, namely, ‘language’ itself, to the debate.  Over the centuries, meanings associated with the expression ‘language’ have been influenced by mappings of conceptual frames and inputs from the biological sciences onto the entity referred to as ‘language’. At the same time the prestige of the ‘science of linguistics’ created a feedback mechanism by which the referentiality of ‘language’, at each stage, was mapped back into the field of evolutionary biology along with the emergent structure(s) of the resulting ‘blend’. While significant energy has been spent on identifying ways in which biological evolution has been linked to concepts of language evolution (Dörries 2002), little attention has been directed to the nature of the conceptual integration networks that have been produced in the process. This paper examines the way conceptual integration theory can be brought to bear on the ‘blends’ that have been created, focusing primarily on examples drawn from 19th century debates concerning the ‘language-species-organism analogy’ in the emerging field of comparative-historical philology.

1.0 Root Metaphors (based on definitions of Pepper 1949; 1962; Nisbet 1969; Bowers 1993)

 

1.1 As Bowers has emphasised: "Cultures, it seems, are based on root metaphors (or what can be called meta-narratives, world views and now paradigms --though this term seems to be more appropriate to a Kuhnian-type discussion). The root metaphor (plural in the case of Western cultures) has changed over time; and if we examine various periods of Western history we find that the creation myth of the Book of Genesis served as a root metaphor that had a profound influence on subsequent cultural patterns....” (Bowers 1993: 93). Moreover, for our purposes here, it is important to stress that “our primary goal is to clarify how metaphorical thinking works as a process of cultural storage, reproduction, and (because thought is metaphorical) re-working old patterns into 'new' (in the weakest sense of the word) ones that will be conceptually coherent with the dominant root metaphor of the cultural group” (Bowers 1993: 93).

 

1.2. “For twenty-five hundred years a single metaphoric conception of change has dominated Western thought. Drawn from the analogy between society and organism, more specifically between social change and the life-cycle of the organism, this metaphor very early introduced into Western European philosophy assumptions and preconceptions regarding change in society that have at no time been without profound influence on Western man’s contemplation of past, present and future” (Nisbet 1969: 211).

 

1.3. In summary, we can state that once particular metaphors become part of the very fabric of scientific discourses, i.e., once they become deeply embedded metaphors that have taken up permanent residence in the generic space and hence backgrounded knowledge of a community of speakers, a knowledge community or epistemic culture, then, as Bono (1990: 81) has alleged, the capacity of individuals, or even scientific communities to control them is, at best, limited. Rather than subjecting themselves to unerring conscious design and authorial control, such scientific metaphors adapt themselves to a larger ecology of affirming or contesting social and cultural values, interests and ideologies. Or Lily Kay has phrased this situation: “Some [metaphors], like the information and code metaphors, are exceptionally potent due to the richness of their symbolism, their synchronic and diachronic linkages, and their scientific and cultural valences” (Kay 2000:3). The same can be said of the staying power of the 19th century language-species-organism metaphor: it is a conceptual blend or integration network that resonated with the times (and continues to do so (cf. Christiansen 1994; Christiansen and Chater forthcoming). In this sense, the 19th century language-species-organism analogy should be understood is an offspring of the larger overarching conceptual network represented by the organic root metaphor of Western culture. Thus, in the 19th century, Social Darwinism succeeded in temporalizing the hierarchically organized, atemporal Great Chain of Being or scala naturae. It was through the Great Chain of Being metaphor which, previously, the associated conceptual networks of the organic root metaphor had been given visual force. That visual aid would be replaced, in part, by another, the genealogical tree of the Indo-European languages and races (cf. quotes under Texual Examples, below, from Schleicher 6.2, 6.3, 6.4 and Haeckel 6.5).

 

2.0 Discussions of Metaphoric Exchange between Comparative-Historical Philology and the Natural Sciences (e.g., comparative anatomy, geology, botany and biology) have been dominated by the following literalist conceptual model of the role of metaphor in scientific discourse (cf. Rudwick quote). 

 

This has given rise to what I call the Standard Analysis of Intrascientific Metaphoric Exchange (exchanges of metaphor between scientific fields), namely, the two-space literalist model of ‘Creative Analogies’. 

 

2.1 ‘Creative Analogies.’

 

Some fifteen years ago, the British historian of science Martin Rudwick noted the following about the desirability of investigating what he terms ‘creative analogies’ in the development of a field of research, especially in its formative stage (cf. Koerner 1995: 48):

 

It is at least arguable that major cognitive innovation is most likely to emerge in the scientific work of individuals who choose to employ analogies that […] are strongly ‘external’: that is, analogies that are furthest removed from the ‘normal practice’ of the discipline concerned. This may happen when a scientific field scarcely yet deserves the name of ‘discipline’, because its practice is not yet strongly insulated and institutionalized (Rudwick 1979:67).

 

2.2 Two-Space Intrascientific Metaphoric Exchanges

 

a. Pilot Discipline: Source-Input Organizing Frame.

 

A field that serves, in its own right, as a source for lending terminology and organizing concepts to other fields, e.g., in matters of methodology as well as, at times, epistemology. According to Konrad Koerner, a pilot discipline is a field that, “owing to its well-established framework of scientific research and the prestige that it enjoys in the eyes of the informed public, provides a model to other fields of study” (Koerner 1995: 70-71; 1980), by “offering its insights, procedures and results to other disciplines” (Koerner 1989: 254; emphasis added).

 

b. Pirate Discipline: Target-Input Organizing Frame

 

A field that is not fully established as an autonomous discipline or subdiscipline, and that, therefore, seeks legitimacy. As a result, it borrows and/or adopts cognitive model(s), important concepts and procedures of investigation from what is perceived to be an established ‘pilot discipline’. As such, it is “a field of study that [is] ready to follow, at times to a considerable degree, the lead of other [pilot] fields … [by] borrowing terms, concepts and methods from other fields” (Koerner 1989: 246, 254; emphasis added).  

 

2.3 Boyd’s Theory-Constitutive Metaphor

 

“[There are cases] in which metaphorical expressions constitute, at least for a time, an irreplaceable part of the linguistic machinery of a scientific theory: cases in which there are metaphors which scientists use in expressing theoretical claims for which no adequate literal paraphrase is known. Such metaphors are constitutive of the theories they express, rather than merely exegetical” (Boyd 1979:360). 

 

As an example, Boyd points to the proliferation of metaphors drawn from computer science and information theory in the ‘relatively young science’ of cognitive psychology. Furthermore, Boyd argues that scientific metaphors, as opposed to literary ones, do not generate ‘strategies for future research’ nor do they undergo any ‘sort of public articulation and development’. In contrast, according to Boyd, theory-constitutive metaphors become “the property of the entire scientific community.” As a result the explication of scientific metaphors ‘is an essential part of the task of scientific inquiry.’  In short, for Boyd, ‘scientific metaphors are chosen for their aptness in capturing an as yet unspecified range of interconnections among potential features of the empirical world which observations lead us to believe exist’ (cf. Bono 1990: 65).

 

As is well known, Black’s ‘interaction theory of metaphor’ explicitly opposes views such as the ‘substitution theory’ in which metaphors can be replaced by literal statements. The ‘substitution theory’ argues that only in the early stages of consolidation does a scientific discipline turn to metaphor as an explanatory and or heuristic device. Later, the metaphors are either abandoned or made explicit, i.e., given discursive definitions based on the insights and theoretical foundations established at that stage by the field in question (cf. Bono 1990: 65).

 

Leaving aside his literalist bias, Boyd (1979), nonetheless, admitted, that metaphors have a significant role to play even within the highly specialized and precise languages of mature sciences. Specifically, he classified these recurring metaphors, analogies as and juxtapositions under the rubric of ‘theory-constitutive metaphors’. 

 

 

3.0 Standard Classification and Functions of Scientific Metaphor (not mutually exclusive categories):

 

a. Illustrative, pedagogical, exegetical: local and transient, used to introduce beginners to complex scientific concepts, e.g., a teacher might such a metaphor to explain to the uninitiated a well-established notion in a mature science.

 

b. Critical-persuasive: Pilot – pirate intrascientific metaphorical exchange, typical of young disciplines, transfers of status and prestige from one field to another and hence, credibility and legitimacy.

 

c. Theory-constitutive metaphor with heuristic value directs the attention of the researchers and leads to productive insights in newly established as well as mature disciplines. No discussion is directed to the avenues of investigation closed of by the non-investigation of disanalogies, i.e., the role of negative selection and projections in guiding research.

 

d. Theory-constitutive metaphor with disciplinary-wide conventionalized meanings, typically found in mature disciplines.

 

In this standard classification no discussion is made of extrascientific metaphoric exchange.   

4.0 Examples of Application of Conceptual Integration Network Theory to the Standard Interpretation:

a.
Heuristic value derives from the emergent structures of the blend: composition, completion and elaboration.

 

b. Optimality constraints contribute increasingly to the creation of conceptual integration networks that are conceptually ‘well-formed’ and explicit; repeatedly running the same ‘blend’ leads to insights as the relevant contents of the input spaces are aligned; discipline wide acceptance results and hence to conventional (dead) metaphors that might be viewed as disciplinarily specific entrenched conceptual networks.

5.0 Extrascientific Metaphoric Exchange:

a. “… all language is metaphoric…if we look at the implications of recent discussions of the theory ladenness of observation, of realism and the use of scientific models, we find that the use of language in scientific theory conforms closely to the metaphoric model. Scientific revolutions are, in fact, metaphoric revolutions, and theoretical models should be seen as metaphoric redescription of the domain of phenomena” (Arbib & Hesse 1986: 150, 156).

 

b. “For twenty-five hundred years a single metaphoric conception of change has dominated Western thought. Drawn from the analogy between society and organism, more specifically between social change and the life-cycle of the organism, this metaphor very early introduced into Western European philosophy assumptions and preconceptions regarding change in society that have at no time been without profound influence on Western man’s contemplation of past, present and future” (Nisbet 1969: 211).

 

c. The organic metaphor and orthogenesis: In the 17th and 18th centuries the organic analogy had been already been linked to the expression ‘evolution’, the latter being understood as the supposed series of changes that a species was predetermined to undergo, like an embryo is preprogrammed to develop. Stated differently, organisms develop and change through pre-programmed inner forces, a theory known in biology as orthogenesis: that evolutionary change is predetermined by the constitution of the germ plasm and independent of external factors. When applied to cultures, peoples, nations and languages, it becomes a theory that alleges all cultures (and languages) pass through the same sequential periods or stages of growth (and decay) in the same order. It is the inner spiritus of the organism that manifests itself, unfolding over time. Change is unidirectional and uniform: determined by the inner nature of the organism, just as an embryo passes through predetermined and irreversible stages, so do all other entities defined as organisms, e.g., nations. Such views persisted into the first half of the 20th century, despite Darwin’s own theory that asserted no such predetermined series or stages. These deterministic views of the organic analogy are called orthogenetic theories ("straight line" theories of evolution) (Mayr 1982), and are in great disfavor today. In the 19th century what Spencer and other ‘Social Darwinists’ added to the gamut of arguments supporting the organic analogy, was the explicit notion of inevitable, orthogenetic, progress (a notion mainly stemming from Spencer, not Darwin) through struggle (interpreted as ferocious fighting and even warfare). The ‘fittest’ was not defined by its reproductive success, but by its physical ability to overcome an opponent. In the popular imagination of the time, Darwin’s term ‘fitness’ quickly lost its purely biological meaning of reproductive success, and over time came to take on the almost exclusive meaning of physical strength or vigor or aggressiveness while these were defined as innate qualities of the organism linked to its inner spirit. If ‘fitness’ is incorrectly interpreted to mean strength, then ‘survival of the fittest’ means ‘survival of the strongest’ rather than ‘propagation of those features which confer the most adaptive advantage.’  

 

d. “Initially, transmutation of species [of a population] could mean one of several things. It generally meant that a species as a whole changed into a more complex species through some (unspecified or vague) process. Darwin had no such intention when he introduced evolutionary theory in the Origin of Species. For a start, he realized that change was not necessarily a process of increasing complexity or perfection. Second, he had a mechanism that explained why new species were different in appearance and behavior — natural selection. Third, Darwin saw that the origin of a new species did not involve an entire species undergoing change. He saw that the origination of a new species occurred in a part of the parental species, in a population. The original species could remain as it was. Species to Darwin were just permanent varieties” (Wilkins 1999; emphasis added).

 

e. Nisbet, too, as well as Black and Pepper, holds that ‘complex philosophical systems can proceed from metaphorical premises.’… Both Black and Nisbet admit the tenacity as well as the potency of metaphors. Nisbet argues that what we usually call revolutions in thought are:

 

Quite often no more than the mutational replacements, at certain critical points in history, of one foundational-metaphor by another in man’s contemplation of universe, society, and self. Metaphoric likening of the universe to an organism in its structure will yield one set of derivations; derivations which become propositions in complex systems of philosophy. [On the other hand,] as happened in the 17th century, [when] the universe is likened instead to a machine, not merely physical science but whole areas of moral philosophy and human psychology are affected (Nisbet 1969: 6; cf. Turner [1974] 199:4 27).

 

 

f. Nisbet’s position is in stark contrast to the literalist dichotomy between scientific and non-scientific discourse. This polarity is reflected in Vicker’s remarks on the difference between early-modern science and magic. Indeed, from the point of view of blending theory, Vicker’s observations about metaphor and analogy in relation to magic could also be applied to the discourse of science:

 

“In the scientific tradition, I hold, a clear distinction is made between words and things and between literal and metaphorical language. The occult tradition does not recognize this distinction: Words are treated as if they are equivalent to things and can be substituted for them. Manipulate the one and you manipulate the other. Analogies, instead of being, as they are in the scientific tradition, explanatory devices subordinate to argument and proof, or heuristic tools to make models that can be tested, corrected, and abandoned if necessary, are, instead, modes of conceiving relationships in the universe that reify, rigidly, and ultimate come to dominate thought. One no longer uses analogies. One is used by them. They become the only way in which one can think or experience the world” (Vickers 1984:95).  

 

g. In conclusion, the organic root metaphor of Western thought and its off-spring, the language-species-organism analogy, involved more than just intrascientific transfer and exchange of meanings between biology and social sciences or between natural science and the emerging field of comparative-historical linguistics, by means of which the prestige of the source discipline enhanced that of the target discipline; or in which metaphorical mimicry served as a rhetorical device to persuade the reader of the credibility and, hence, correctness of the model proposed, whether biological or linguistic. Rather over time such complex analogies or entrenched conceptual networks, drawing upon the cultural stereotypes and popular metaphors of their epoch (the background knowledge intrinsic to their synchronic and diachronic generic space), act powerfully upon scientific inquiry by constructing the very categories and hence ‘facts,’ that scientists use to frame and test hypotheses. Thus, for Stefan (1986:271-274), metaphor or analogy is constitutive both of scientific theory and of the categories of experience that underlie scientific discovery –which both highlight and suppress features of the perceived world (cf. Bono 1990: 71).

  

6.0 Textual Examples of Intrascientific and Extrascientific Metaphoric Exchange:

 

6.1. Bopp, F.  [1827] 1836. Vocalismus…

 

“Languages must be taken as organic natural bodies which form themselves according to definite laws, develop carrying in themselves an internal life principle, and gradually die, since they do not understand themselves any longer and shed or mutilate or misuse, i.e., use for purposes for which they were not originally meant, members and forms which initially were significant, but in time have become a mass of largely external nature“ (Bopp [1827] 1836, cf. Morpurgo Davies 1987: 84).

 

6.2. Darwin, C. 1859. On the Origin of Species by Means of Natural Selection; or, The Preservation of Favoured Races.

 

“In his chapter on classification and systematics, for instance, Darwin observed, ‘If we possessed a perfect pedigree of mankind, a genealogical arrangement of the races of man would afford the best classification of the various languages now spoken throughout the world; and if all extinct languages, and all intermediate and slowly changing dialects, had to be included, such an arrangement would, I think, be the only possible one.’ In this passage, Darwin recognized the isomorphism between language descent and human biological descent. Not only could the human pedigree serve as a model for tracing linguistic development, as he here emphasized, but also the reverse, as he implied, could be the case: the descent of language might serve as a model for the descent of man” (Richards 2002: 24; emphasis added).

 

6.3. Schleicher, A. 1863. Die Darwinische Theorie und die Sprachwissenschaft (Darwinian Theory and the Science of Language). The title of its English translation which appeared in 1869, i.e., three years before Darwin would publish his Descent of Man (1971), was more openly provocative: Darwinism Tested by the Science of Language.

 

Languages are organisms of nature; they have never been directed by the will of man; they rose, and developed themselves according to definite laws; they grew old, and died out. They, too, are subject to that series of phenomena which we embrace under the name of ‘life.’ The science of language is consequently a natural science; its method is generally altogether the same as that of any natural science. …

 

Now we observe during historical periods how species and genera of speech disappear, and how others extend themselves at the expense of the dead. I only remind you, by way of illustration, of the spread of the Indo-European family

 

‘If any group has once been extinguished it can never appear again, because a chain in the link of generation has been broken.’ ‘This explains how the extension of dominant species which admit of the greatest variation, peopled the earth in the course of time with other forms of life, closely related though modified; and how these generally succeed in supplanting those groups of species which succumb to them in the struggle for existence’ [material enclosed in quotes, i.e., the previous two sentence, is where Schleicher is quoting directly from Darwin’s Origin]. Not a word of Darwin’s need be changed here if we wish to apply this reasoning to the languages. Darwin describes here with striking accuracy the process of the struggle for existence in the field of human speech. In the present period of the life of man the descendents of the Indo-Germanic family are the conquerors in the struggle for existence; they are engaged in continual extension, and have already supplanted or dethroned numerous other idioms. The multitude of the Indo-Germanic species and sub-species is illustrated by our genealogical tree” (Schleicher 1863: 20-21, 60, 63-64; emphasis added).

 

6.4. Schleicher, A. 1865. Über die Bedeutung der Srpach für Naturgeschichte des Menschen (On the Significance of Language in the Natural History of Mankind).  

 

“How inconstant are the formation of the skull and other so-called racial differences. Language, by contrast, is always a constant trait. A German can indeed display hair and prognathous jaw to match those of the most distinctive Negro head, but he will never speak a Negro language with native fluency…. Animals can be ordered according to their morphological character. For man, however, the external form has, to a certain extent, been superseded; as an indicator of his true being, external form is more or less insignificant. To classify human beings we require, I believe, a higher criterion, one which is an exclusive property of man. This, we find, as I have mentioned, in language” (Schleicher 1865: 16, 18-19; cited in Richards 2002: 30). 

 

 

6.5. Haeckel, E. 1868. Die Natürliche Schöpfungsgeschichte (The Natural History of Creation).

 

“We must mention here one of the most important results of the comparative study of languages, which for the Stammbaum of the species of men is of the highest significance, namely, that human languages probably had a multiple or polyphyletic origin. Human language as such probably developed only after the species of speechless Urmenschen or Affenmenschen had split into several species or kinds. With each of these human species, language developed on its own and independently of the others. At least this is the view of Schleicher, one of the foremost authorities on the subject. … If one views the origins of the branches of language as the special and principal act of becoming human, and the species of humankind as distinguished according to their language stem, then one can say that the different species of men arose independently of one another” (Haeckel 1868: 511; cited in Richards 2002: 45; emphasis added).

 

 

6.6 Whitney, W. D. 1867. Language and the Study of Language.

 

“What makes a physical science is that it deals with material substances, acted on by material forces. In the formation of geological strata, the ultimate cognizable agencies are the laws of matter: the substance affected is tangible matter; the product is inert, insensible matter. In zoology, again, as in anatomy and physiology, the investigator has to do with material structure, whose formation is dependent on laws implanted in matter itself, and beyond the reach of voluntary action. In language on the other hand, the ultimate agencies are intelligent beings… What but an analogical resemblance can there possibly be between the studies of things so essentially dissimilar?” (Whitney 1967: 49, cited in Koerner 1992: 277-8).

 

“There is yet a clear parallelism between the life of language and that of the animal kingdom in general. The speech of each person is, as it were, an individual of a species, with its general inherited conformity to the specific type, but also with its individual peculiarities, its tendency to variation and the formation of a new species. The dialects, languages, groups, families, stocks, set up by the linguistic student, correspond with the varieties, species, genera, and so on, of the zoologist. And the questions of which the students of nature are so excitedly discussing at the present day [i.e., in 1867: K.K.] –the nature of specific distinctions, the derivation of species, by individual variation and natural selection, the unity of origin of animal– all are closely akin with those which the linguistic student has constant occasion to treat” (Whitney, 1867: 46-47; cited in Koerner 1992: 277).

Language as an organism: A connectionist perspective on the acquisition, processing and evolution of language. Oxford University Press].

 

“.... we must refocus by observing that natural languages exist only because humans can produce, learn and process them. In this connection, it is useful to construe language as an organism, adapted through natural selection to fit a particular ecological niche: the human brain. Darwin (1900) was one of the first to recognize this as is evident from the following quote:

 

The formation of different languages and of distinct species, and the proofs that both have been developed through a gradual process, are curiously parallel: We find in distinct languages striking homologies due to community of descent, and analogies due to a similar process of formation. The manner in which certain letters or sounds change when other change is very like correlated growth … Languages, like organic beings, can be classed in groups under groups; and they can be classed either naturally, according to descent, or artificially by other characters. Dominant languages and dialects spread widely and lead to the gradual extinction of other tongues. A language, like a species, when once extinct, never … reappears… A struggle for life is constantly going on among the words and grammatical forms in each language. The better, the shorter, the easier forms are constantly gaining the upper hand… The survival and preservation of certain favored words in the struggle for existence is natural selection (Darwin [1871] 1900, p. 106). 

 

In this sense, natural language is akin to an organism whose evolution has been constrained by the properties of human learning and processing mechanisms.  … Following Darwin, I propose to view natural language as a kind of beneficial parasite –i.e., a nonobligate symbiant- that confers some selective advantage onto its human hosts without whom it cannot survive “(Christiansen 1994: 125-126).

 

6.8. Language appears to be a complex adaptive system that is constantly constructed and reconstructed by its users. In turn the language users themselves must be modeled as grounded, distributed autonomous agents. Hence, language must be considered an emergent phenomenon, the result of the behavior of these agents. Population thinking must replace the older typological or essential viewpoint, i.e., based on the language-species-organism analogy (cf. Steels 1999, 2002). 

 

“In theory, a species consists of all organisms which have similar characteristics, specifically which can interbreed…. Darwin proposed a profound paradigm shift from a typological view of species to a population view (Mayr 1975). I will argue that such a shift of viewpoint is also required in linguistics. The typological or essentialist view, exemplified by the work of Linnaeus, considers all the members of a species as belonging to a certain (ideal) type.  …. Darwin introduced instead a population viewpoint in biology, which considers every organism as unique and undergoing change during its lifetime. Rather than viewing a species as a type, it is seen as a relatively loose collection with fuzzy boundaries that can only be circumscribed statistically. Natural selection does not work on types but on individuals” (Steels 1999: 144).
