“Nor was even this the end of attempts at creating a philosophic language. In 1772 there appeared the project of Georg Kalmar, Praecepta grammatica atque specimina linguae philosophicae sive universalis, ad omne vitae genus adcomodatae, which occasioned the most significant discussion on our topic written in Italian.

In 1774, the Italian-Swiss Father Francesco Soave published his Riflessioni intorno alla costituzione di una lingua universaleSoave, who had done much to spread the sensationalist doctrine to Italy, advanced a criticism of the a priori languages that anticipated those made by the Idéologues (on Soave see Gensini 1984; Nicoletti 1989; Pellerey 1992a).

Displaying a solid understanding of the projects from Descartes to Wilkins and from Kircher to Leibniz, on the one hand Soave advanced the traditional reservation that it was impossible to elaborate a set of characters sufficient to represent all fundamental concepts; on the other hand, he remarked that Kalmar, having reduced these concepts to 400, was obliged to give different meanings to the same character, according to the context.

Either one follows the Chinese model, without succeeding in limiting the characters, or one is unable to avoid equivocations.

Unfortunately, Soave did not resist the temptation of designing a project of his own, though outlining only its basic principles. His system of classification seems to have been based on Wilkins; as usual he sought to rationalize and simplify his grammar; at the same time, he sought to augment its expressive potential by adding marks for new  morphological categories such as dual and the neuter.

Soave took more care over his grammar than over his lexicon, but was mainly interested in the literary use of language: from this derives his radical skepticism about any universal language; what form of literary commerce, he wondered, could we possibly have with the Tartars, the Abyssinians or the Hurons?

In the early years of the next century, Soave’s discussion influenced the thinking of Giacomo Leopardi, who had become an exceptionally astute student of the Idéologues.

In his Zibaldone, Leopardi treated the question of universal languages at some length, as well as discussing the debate between rationalists and sensationalists in recent French philosophy (see Gensini 1984; Pellerey 1992a).

Leopardi was clearly irritated by the algebraic signs that abounded in the a priori languages, all of which he considered as incapable of expressing the subtle connotations of natural languages:

“A strictly universal language, whatever it may be, will certainly, by necessity and by its natural bent, be both the most enslaved, impoverished, timid, monotonous, uniform, arid, and ugly language ever.

It will be incapable of beauty of any type, totally uncongenial to imagination [ . . . ] the most inanimate, bloodless, and dead whatsoever, a mere skeleton, a ghost of a language [ . . . ] it would lack life even if it were written by all and universally understood; indeed it will be deader than the deadest languages which are no longer either spoken or written.” (23 August 1823, in G. Leopardi, Tutte le opere, Sansoni: Florence 1969: II, 814).

Despite these and similar strictures, the ardor of the apostles of philosophic a priori languages was still far from quenched.

At the beginning of the nineteenth century, Anne-Pierre-Jacques de Vismes (Pasilogie, ou de la musique considérée come langue universelle, 1806) presented a language that was supposed to be a copy of the language of the angels, whose sounds derived from the affections of the soul.

Vismes argued that when the Latin translation of Genesis 11:1-2 states that “erat terra labii unius” (a passage to which we usually give the sense that “all the world was of one language”), it used the word labium (lip) rather than lingua (tongue) because people first communicated with each other by emitting sounds through their lips without articulating them with their tongue.

Music was not a human invention (pp. 1-20), and this is demonstrated by the fact that animals can understand music more easily than verbal speech: horses are naturally roused by the sound of trumpets as dogs are by whistles. What is more, when presented with a musical score, people of different nations all play it the same way.

Vismes presents enharmonic scales of 21 notes, one for each letter of the alphabet. He did this by ignoring the modern convention of equal temperament, and treating the sharp of one note as distinct from the flat of the note above.

Since Vismes was designing a polygraphy rather than a spoken language, it was enough that the distinctions might be exactly represented on a musical stave.

Inspired, perhaps, indirectly by Mersenne, Vismes went on to demonstrate that if one were to combine his 21 sounds into doublets, triplets, quadruplets, etc., one would quickly arrive at more syntagms than are contained in any natural language, and that “if it were necessary to write down all the combinations that can be generated by the seven enharmonic scales, combined with each other, it would take almost all of eternity before one could hope to come to an end.” (p. 78).

As for the concrete possibility of replacing verbal sounds by musical notes, Vismes devotes only the last six pages of his book to such a topic–not a great deal.

It never seems to have crossed Visme’s mind that, in taking a French text and substituting tones for its letters, all he was doing was transcribing a French text, without making it comprehensible to speakers of other languages.

Vismes seems to conceive of a universe that speaks exclusively in French, so much so that he even notes that he will exclude letters like K, Z and X because “they are hardly ever used in languages” (p. 106).”

Eco: The “Library” of Leibniz and the Encyclopédie


Jean le Rond d’Alembert and Denis Diderot, Figurative System of Human Knowledge, or the Tree of Diderot and d’Alembert, from the Encyclopédie, circa 1752. This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author’s life plus 100 years or less. 

“During the Enlightenment there began to develop a critical attitude towards any attempt to construct a system of a priori ideas. It was a critique founded, in large part, upon the considerations advanced by Leibniz.

Thus it was in terms that closely recalled Leibniz’s own description of an ideal library that, in his introduction to the Encyclopédie, d’Alembert was to sound the death knell for projects for philosophical a priori languages.

Presented with the practical problem of organizing an encyclopedia and justifying the way that it divided its material, the system of scientific knowledge began to take on the appearance of a labyrinth, a network of forking and twisting paths that put paid to any notion that knowledge might be represented in a tree diagram of any sort.

Knowledge might still be divided into branches, “some of which converge at a common center; and, since, starting from the center, it is impossible to follow all the branches at once, the choice [of pathway] is determined by the nature of the different intellects.”

The philosopher was whoever discovered the hidden passageways within that labyrinth, the provisional interconnections, the web of mutually dependent associations which constituted such a network as a geographical representation.

For this reason the authors of the Encyclopédie decided that each single article would appear as only one particular map, which, in its small way, might reflect the entire global map:

“objects approach each other more or less closely, presenting different aspects according to the perspective chosen by the particular geographer [ . . . ].

Thus it is possible to imagine that there are as many systems of human knowledge as there are representations of the world constructed according to differing projections [ . . . ].

Often, an object placed in one particular class on account of one or another of its properties may reappear in another class because of other properties.”

Following the suggestion of Locke, the Enlightenment was less concerned with the search for perfect languages than with the provision of therapies for already existing ones.

After denouncing the limits of natural languages, Locke (Essay, III, X) had passed to an analysis of the abuse which must occur whenever words are used that do not correspond to clear and distinct ideas, whenever they are used inconsistently, whenever they are employed with the affectation of obscurity, whenever words are taken for things, whenever they are used for things which possess no meaning, and whenever we imagine that others must necessarily associate with the words we use the same ideas as we do.

Locke fixed a set of norms to combat these abuses, and, since Locke was not concerned with lexical or syntactical reform, but simply with subjecting usage to a measure of vigilance and philosophical common sense, these norms had no bearing on the theme of philosophical languages.

Instead of a systematic reform of language, Locke modestly suggested that we be more conscientious in the way we use words to communicate with one another.

This was to be the line adopted by the encyclopedists of the Enlightenment and those whom they inspired.

The encyclopedists launched their attack on philosophical a priori languages principally in their entry under the heading “Caractère,” which was the result of the collaboration of several authors.

Du Marsais made an initial distinction between numerical characters, characters representing abbreviations, and literal characters; these last were further subdivided into emblematic characters (still the accepted interpretation of hieroglyphics) and nominal characters, primarily the characters of the alphabet.

D’Alembert accepted the criticisms that had traditionally been made of the characters used in natural languages, and then discussed the various projects for the construction of real characters, showing an extensive knowledge of the projects in the previous century.

It was a discussion which often confused characters that were ontologically real, that directly expressed, that is, the essence of the things they represented, with characters that were only logically real, capable, that is, of expressing by convention a single idea unequivocally. Still, d’Alembert advanced a number of criticisms that applied equally to both types.

In contrast to those of the seventeenth century, philosophers in the Enlightenment had radically changed the focus of their reflection on language. It now seemed clear that thought and language influenced each other, each proceeding with the other step by step, and that, consequently, language, as it evolved, would constantly modify thought.

Thus it no longer made sense to accept the rationalist hypothesis of a single grammar of thought, universal and stable, which all languages in one way or another reflected. No system of ideas postulated on the basis of abstract reasoning could thus ever form an adequate parameter of and criterion for the formation of a perfect language.

Language did not reflect a preconstituted mental universe, but collaborated in its growth.

The Idéologues demonstrated the impossibility of postulating a universal way of thinking, independent of the human semiotic apparatus. Destutt de Tracy (Eléments d’idéologie, I, 546, n.) argued that it was not possible to confer on all languages the attributes of algebra. In the case of natural languages:

“we are often reduced to conjectures, inductions, and approximations [ . . . ]. Almost never can we have a perfect certainty that an idea which we have constructed for ourselves under a certain sign and by various means is really utterly and entirely the same as the idea that those who taught us the sign as well as anyone else who might subsequently use the sign might attribute to it.

Hence words may often, insensibly, take on differences in meaning without anyone noting these changes; for this reason we might say that while every sign is perfectly transparent for whomever invents it, it is somewhat vague and uncertain for those who receive it [ . . . ].

I might even carry this further: I said that every sign is perfect for whomever invents it, but this is only really true at the precise instant when he invents the sign, for when he uses this same sign in another moment in his life, or when his mind is in another disposition, he can no longer be entirely sure that he has gathered up under this sign the same collection of ideas as he had the first time he used it.” (pp. 583-5).

Tracy understood that the prerequisite of all philosophical languages was the absolute and univocal correspondence between signs and the ideas they represented. An examination, however, of the seventeenth century English systems led him to the conclusion that “it is impossible that the same sign possess the same meaning for all who use it [ . . . ]. We thus must give up the idea of perfection.” (Eléments d’idéologie, II, 578-9).

This was a theme that was common to empiricist philosophy, to which all the Idéologues referred. Locke had already noted that although the names glory and gratitude were

“the same in every Man’s mouth, through a whole country, yet the complex, collective Idea, which everyone thinks on, or intends by that name, is apparently very different in Men using the same language. [ . . . ]

For though in the Substance Gold, one satisfies himself with Color and Weight, yet another thinks solubility in Aqua Regia, as necessary to be join’d with that Color in his Idea of Gold, as any one does its Fusibility; Solubility in Aqua Regia, being a Quality as constantly join’d with its Color and and Weight, as Fusibility, or any other; others put its Ductility or Fixedness, etc. as they had been taught by Tradition and Experience.

Who, of all these, has establish’d the right termination of the word Gold?” (Essay, III, IX, 8, 13).

Returning to the Idéologues, Joseph-Marie Degérando, whose criticisms of Wilkins we have already encountered, observed (Des signes et l’art de penser considérés dans leur rapports mutuels, 1800) that the ensemble of associated ideas represented by the word man would be more extensive in the mind of a philosopher than in that of a common laborer, and that the word liberty could not have meant in Sparta what it did in Athens (I, 222-3).

The impossibility of elaborating a philosophic language is finally due to the fact that since languages develop through a set of stages, a development that the Idéologues delineated with great precision, there was no way of deciding the linguistic stage of development that a perfect language should represent.

Choosing to reflect one stage rather than another, a philosophical language will then continue to reflect all the limitations of that linguistic stage, while just to overcome these limitations humanity had passed to further and more articulate stages.

Once it had been perceived that the process of linguistic change is continuous, that language is subject to change not only at its prehistoric point of origin, but also in the present day, it became obvious that any thought of reviving the idea of a philosophic language was destined to fail.”

Eco: Philosophers Against Monogeneticism, 2

“In his Essai sur l’origine des connaissances humaines (1746), Condillac took Locke’s empiricism and reduced it to a radical sensationalism. According to Condillac, it was not only perception that derived from the senses, but all the working of our minds–memory, awareness, comparison and, consequently, judgement.

If a statue could be made possessing an internal organization identical to our own, Condillac argued, that statue would gradually, through its primary sensations of pain and pleasure, derive a collection of abstract notions identical to our own.

In this genesis of ideas, signs play a fundamental role: they express at first our primary feelings, by cries and gestures–a language of action. Afterwards this purely emotional language evolves to function as the mode in which we fix our thoughts–a language of institution.

The notion of a language of action had already been expressed by William Warburton (The Divine Legation of Moses, 1737-41). It was an idea that was to become an important tenet of sensationalist philosophy, as it provided a link that helped explain how human beings had passed from simple, immediate responses to more complex forms of cultural behavior, in the course of an irreversible historical development.

At the very end of the century, the Idéologues began to fill this picture in, elaborating a vision of the early course of human history that was, at once, materialist, historicist and sensitive to social factors.

They began to investigate every form of expression: various types of pictographic sign, gestures in the pantomime or in the language of deaf-mutes, orators and actors, algebraic characters, the jargons and passwords of secret societies (for it was in this period that masonic confraternities were founded and spread).

In works such as the Eléments d’idéologie by Antoine-Louis-Claude Destutt De Tracy (1801-15, 4 vols) and, even more, Des signes by Joseph-Marie de Degérando (1800: I, 5) a great historic panorama began to emerge.

At the first stage, human beings sought to make their intentions known to each other through simple actions; at the next stage they passed gradually to a language of nature, that is, an imitative language in which they could represent, by a sort of pantomime, a real action.

This would be a language still subject to misunderstandings, for there would be nothing to guarantee that both parties in a conversation would associate the mimed sign with the same idea, and that, consequently, the receiver would draw the intended conclusions about the purposes and circumstances for which the pantomime had been enacted.

Where the purpose was to refer to an object that was actually present, all that was necessary was a sign we might call indexical–a cry or glance in the direction of the object, a pointing of a finger.

Indexical signs would no longer do, however, where the intention was to refer to an object not present, either because the object was physically located at some other place or time, or because the “object” was, in fact, an interior state.

Where the absent object was physical and material, a mimed imitation might still be able to denote it–trying to imitate not substances but actions. To refer to non-physical, interior states, however, it was necessary to develop a more figurative language, a language of metaphor, synecdoche and metonymy.

Two weights hefted by the hands might, for example, suggest making a judgement between two parties; a flame might symbolize an ardent passion, and so on. Up to this point, we are still in a language of analogies, expressed in gestures, cries and primitive onomatopoeia, or by a symbolic or pictographic form of writing.

Slowly, however, these signs of analogy become signs of habitude; they are codified, more or less arbitrarily, up to the birth of a language in the strict sense of the term. Thus the semiotic machinery constructed by humanity is determined by environmental and historical factors.

This elaboration by the Idéologues implied a cogent and devastating critique of any idea of a perfect original language. It is a critique, moreover, that brought an argument initiated over two centuries earlier to a close.

This was the argument that had begun with the rediscovery of the hypothesis of Epicurus, and with the first reflections of Montaigne and Locke on the variety of cultures and the differences in beliefs among the variety of exotic peoples that the accounts of the explorers of their times were revealing.

Thus, under the entry “Language” in the Encyclopédie, Jaucourt could say that since languages were all reflections of the “genius” of the various peoples, it is impossible to conceive of a universal tongue.

Since customs and ideas were determined by climate, upbringing and government, it was not possible to impose the same customs, or the same ideas of vice and virtue, on all nations.

In this formulation, the notion of “genius” was employed as a means of explaining how each language contains its own particular vision of the world. Yet such a notion also implies that languages were mutually incommensurable.

This was an idea that already appears in Condillac (Essai sur l’origine des connaissances humaines, II, I, 5). It also appeared in Herder (Fragmente über die neuere deutsche Literatur, 1766-7), and was developed by Humboldt (Fragmente über die Verschiedenheit des menschlichen Sprachbaues und ihren Einfluss auf die geistige Entwicklung des Menschengeschlechts, 1836), for whom every language possesses its own innere Sprachform, an inner form expressing the vision of the world of the people who speak it.

When one assumes that there is an organic relation and a reciprocal influence between language and thought, it is clear that such an interaction does not only work within a given language at a given historical time: it affects the very historical development of every language and of every culture. (cf. De Mauro 1965: 47-63).”
