1908-kl-t-zamenhof

L.L. Zamenhof (1859-1917), creator of the IAL Esperanto. This photo from the Congressional Book of the 4th World Esperanto Congress in Dresden, 1908. 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. 

Esperanto was first proposed in 1887 in a book, written in Russian and published in Warsaw at the Kelter Press, entitled The International Language. Preface and Complete Manual (for Russians). The author’s name was Dr. Ledger Ludwik Zamenhof; yet he wrote the book under the pseudonym Dr. Esperanto (Dr. Hopeful), and this was soon adopted as the name of his language.

Zamenhof, born in 1859, had been fascinated with the idea of an international language since adolescence. When his uncle Josef asked him what was the non-Hebrew name he had, according to custom, chosen for his contacts with Gentiles, the seventeen year old Zamenhof replied that he had chosen Ludwik because he had found a reference to Lodwick (also spelled Lodowick) in a work by Comenius (letter of 31 March 1876; see Lamberti 1990: 49).

Zamenhof’s origins and personality helped shape both his conception of the new language and its eventual success. Born of a Jewish family in Bialystok, an area of Polish Lithuania then part of the Tsarist empire, Zamenhof passed his childhood in a crucible of races and languages continually shaken by nationalist ferment and lasting waves of anti-Semitism.

The experience of oppression, followed by the persecution of intellectuals, especially Jewish, at the hands of the Tsarist government, ensured that Zamenhof’s particular fascination with international languages would become mixed with a desire for peace between peoples.

Besides, although Zamenhof felt solidarity towards his fellow Jews and forecast their return to Palestine, his form of secular religiosity prevented him from fully supporting Zionist ideas; instead of thinking of the end of the Diaspora as a return to Hebrew, Zamenhof hoped that all the Jews could be, one day, reunited in an entirely new language.

In the same years in which, starting in the Slavic-speaking lands, Esperanto began its spread throughout Europe–while philanthropists, linguists and learned societies followed its progress with interest, devoting international conferences to the phenomenon–Zamenhof had also published an anonymous pamphlet, which extolled a doctrine of international brotherhood, homaranism.

Some of his followers successfully insisted on keeping the Esperanto movement independent of ideological commitments, arguing that if Esperanto were to succeed, it would do so only by attracting to its cause men and women of different religious, political and philosophical opinions.

They even sought to avoid any public reference to Zamenhof’s own Jewish origins, given that–it must be remembered–just at that historical moment there was growing up the theory of a great “Jewish conspiracy.”

Even so, despite the movement’s insistence on its absolute neutrality, the philanthropic impulse and the non-confessional religious spirit that animated it could not fail to influence the followers of the new language–or samideani, that is, participating in the same ideal.

In the years immediately following its emergence, moreover, the language and its supporters were almost banned by the Tsarist government, congenitally suspicious towards idealism of any sort, especially after Esperanto had had the fortune / misfortune to obtain the passionate support of Tolstoy, whose brand of humanist pacifism the government regarded as a dangerous form of revolutionary ideology.

Even the Nazis followed suit, persecuting Esperanto speakers in the various lands under their occupation (cf. Lins 1988). Persecution, however, only reinforces an idea: the majority of international languages represented themselves as nothing more than instruments of practical utility; Esperanto, by contrast, came increasingly to gather in its folds those religious and pacifist tensions which had been characteristics of many quests for a perfect language, at least until the end of the seventeenth century.

Esperanto came to enjoy the support and sympathy of many illustrious figures–linguists such as Baudoin de Courtenay and Otto Jespersen, scientists such as Peano, or philosophers such as Russell. Rudolf Carnap‘s comments are particularly revealing; in his Autobiography (in Schilpp 1963: 70) he described feeling moved by a sense of solidarity when he found himself able to converse with people of other countries in a common tongue.

He noted the quality of this living language which managed to unify a surprising degree of flexibility in its means of expression with a great structural simplicity. Simplest perhaps was the lapidary formulation of Antoine Meillet: “Toute discussion théoretique est vaine: l’Esperanto fonctionne” (Meillet 1918: 268).

Today the existence of the Universala Esperanto-Asocio in all of the principal cities of the world still testifies to the success of Zamenhof’s invention. Over one hundred periodicals are currently published in Esperanto, there is an original production of poetry and narrative, and most of the world literature has been translated into this language, from the Bible to the tales of Hans Christian Andersen.

Like Volapük, however, especially in the first decades, the Esperanto movement was nearly torn apart by battles raging over proposed lexical and grammatical reforms. In 1907, Couturat, as the founder and secretary of the Delégation pour l’adoption d’une langue auxiliaire internationale, attempted what Zamenhof considered a coup de main: he judged Esperanto to be the best IAL, but only in its approved version, that is, only in the version that had been reformed by the French Esperanto enthusiast, Louis De Beaufront, and renamed Ido.

The majority of the movement resisted the proposed modifications, according to a principle stated by Zamenhof: Esperanto might accept enrichments and lexical improvements, but it must always remain firmly attached to what we might call the “hard core” as set down by its founder in Fundamento de Esperanto (1905).

Eco: The Mixed Systems

JMSchleyer1888

Johann Martin Schleyer (1831-1912), a drawing of the creator of Volapük by Theodor Mayerhofer (1855-1941) in Sigmund Spielmann, Volapük- Almanach für 1888, Leipzig. 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. 

Volapük was perhaps the first auxiliary language to become a matter of international concern. It was invented in 1879 by Johann Martin Schleyer, a German Catholic priest who envisioned it as an instrument to foster unity and brotherhood among peoples.

As soon as it was made public, the language spread, expanding throughout south Germany and France, where it was promoted by Auguste Kerkhoffs. From here it extended rapidly throughout the whole world.

By 1889 there were 283 Volapükist clubs, in Europe, America and Australia, which organized courses, gave diplomas and published journals. Such was the momentum that Schleyer soon began to lose control over his own project, so that, ironically, at the very moment in which he was being celebrated as the father of Volapük, he saw his language subjected to “heretical” modifications which further simplified, restructured and rearranged it.

Such seems to be the fate of artificial languages: the “word” remains pure only if it does not spread; if it spreads, it becomes the property of the community of its proselytes, and (since the best is the enemy of the good) the result is “Babelization.”

So it happened to Volapük: after a few short years of mushroom growth, the movement collapsed, continuing in an almost underground existence. From its seeds, however, a plethora of new projects were born, like the Idiom Neutral, the Langue Universelle of Menet (1886), De Max’s Bopal (1887), the Spelin of Bauer (1886), Fieweger’s Dil (1887), Dormoy’s Balta (1893), and the Veltparl of von Arnim (1896).

Volapük was an example of a “mixed system,” which, according to Couturat and Leau, followed the lines sketched out by Jacob von Grimm. It resembles an a posteriori language in the sense that it used as its model English, as the most widely spread of all languages spoken by civilized peoples (though, in fact, Schleyer filled his lexicon with terms more closely resembling his native German).

It possessed a 28 letter alphabet in which each letter had a unique sound, and the accent always fell on the final syllable. Anxious that his should be a truly international language, Schleyer had eliminated the sound r from his lexicon on the grounds that it was not pronounceable by the Chinese–failing to realize that for the speakers of many oriental languages the difficulty is not so much pronouncing r as distinguishing it from l.

Besides, the model language was English, but in a sort of phonetic spelling. Thus the word for “room” was modeled on English chamber and spelled cem. The suppression of letters like the r sometimes introduced notable deformations into many of the radicals incorporated from the natural languages.

The word for “mountain,” based on the German Berg, with the r eliminated, becomes bel, while “fire” becomes fil. One of the advantages of a posteriori language is that its words can recall the known terms of a natural language: but bel for a speaker of a Romance language would probably evoke the notion of beautiful (bello), while not evoking the notion of mountain for a German speaker.

To these radicals were added endings and other derivations. In this respect, Volapük followed an a priori criterion of rationality and transparency. Its grammar is based upon a declensional system (“house:” dom, doma, dome, domi, etc.).

Feminine is derived directly from masculine through an invariable rule, adjectives are all formed with the suffix –ik (if gud is the substantive “goodness,” gudik will be the adjective “good”), comparatives were formed by the suffix –um, and so on.

Given the integers from 1 to 9, by adding an s, units of ten could be denoted (bal = 1, bals = 10, etc.). All words that evoke the idea of time (like today, yesterday, next year) were prefixed with del-; all words with the suffix –av denoted a science (if stel = “star,” then stelav = “astronomy”).

Unfortunately, these a priori criteria are used with a degree of arbitrariness: for instance, considering that the prefix lu– always indicates something inferior and the term vat means “water;” there is no reason for using luvat for “urine” rather than for “dirty water.” Why is flitaf (which literally means “flying animal”) used for “fly” and not for “bird” or “bee?”

Couturat and Leau noted that, in common with other mixed systems, Volapük, without claiming to be a philosophical language, still tried to analyze notions according to a philosophical method.

The result was that Volapük suffered from all the inconveniences of the a priori languages while gaining none of their logical advantages. It was not a priori in that it drew its radicals from natural languages, yet it was not a posteriori, in so far as it subjected these radicals to systematic deformations (due to an a priori decision), thus making the original words unrecognizable.

As a result, losing all resemblance to any natural language, it becomes difficult for all speakers, irrespective of their original tongue. Couturat and Leau observe that mixed languages, by following compositional criteria, form conceptual agglutinations which, in their awkwardness and their primitiveness, bear a resemblance to pidgin languages.

In pidgin English, for example, the distinction between a paddle wheeler and a propeller-driven steam boat is expressed as outside-walkee-can-see and inside-walkee-no-can-see.

Likewise, in Volapük the term for “jeweler” is nobastonacan, which is formed from “stone” + “merchandise” + “nobility.”

Eco: The International Auxiliary Languages

Couturat & Leau, Histoire de la Langue Universelle, 1903

Louis Couturat (1868-1914) & Léopold Leau (1868-1943), Histoire de la langue universelle, Hachette, Paris, 1903, held in the Bibliothèque nationale de France, and archive.org. 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. 

“The dawn of the twentieth century witnessed a revolution in transport and communications. In 1903 Couturat and Leau noted that it was now possible to voyage around the world in just forty days; exactly one half of the fateful limit set by Jules Verne just thirty years before.

Now the telephone and the wireless knitted Europe together and as communication became faster, economic relations increased. The major European nations had acquired colonies even in the far-flung antipodes, and so the European market could extend to cover the entire earth.

For these and other reasons, governments felt as never before the need for international forums where they might meet to resolve an infinite series of common problems, and our authors cite the Brussels convention on sugar production and international accord on white-slave trade.

As for scientific research, there were supranational bodies such as the Bureau des poides et  mesures (sixteen states) or the International Geodesic Association (eighteen states), while in 1900 the International Association of Scientific Academies was founded.

Couturat and Leau wrote that such a growing of scientific information needed to be organized “sous peine de revenir à la tour de Babel.”

What could the remedy be? Couturat and Leau dismissed the idea of choosing a living language as an international medium as utopian, and found difficulties in returning to a dead language like Latin.

Besides, Latin displays too many homonyms (liber means both “book” and “free”), its flexions create equivocations (avi might represent the dative and ablative of avis or the nominative plural of avus), it makes it difficult to distinguish between nouns and verbs (amor means both love and I am loved), it lacks a definite article and its syntax is largely irregular . . . The obvious solution seemed to be the invention of an artificial language, formed on the model of natural ones, but which might seem neutral to all its users.

The criteria for this language should be above all a simple and rational grammar (as extolled by the a priori languages, but with a closer analogy with existing tongues), and a lexicon whose terms recalled as closely as possible words in the natural languages.

In this sense, an international auxiliary language (henceforth IAL) would no longer be a priori but a posteriori; it would emerge from a comparison with and a balanced synthesis of naturally existing languages.

Couturat and Leau were realistic enough to understand that it was impossible to arrive at a preconceived scientific formula to judge which of the a posteriori IAL projects was the best and most flexible. It would have been the same as deciding on allegedly objective grounds whether Portuguese was superior to Spanish as a language for poetry or for commercial exchange.

They realized that, furthermore, an IAL project would not succeed unless an international body adopted and promoted it. Success, in other words, could only follow from a display of international political will.

What Couturat and Leau were facing in 1903, however, was a new Babel of international languages invented in the course of the nineteenth century; as a matter of fact they record and analyze 38 projects–and more of them are considered in their further book, Les nouvelles langues internationales, published in 1907.

The followers of each project had tried, with greater or lesser cohesive power, to realize an international forum. But what authority had the competence to adjudicate between them?

In 1901 Couturat and Leau had founded a Delégation pour l’adoption d’une langue auxiliaire internationale, which aimed at resolving the problem by delegating a decision to the international Association of Scientific Academies.

Evidently Couturat and Leau were writing in an epoch when it still seemed realistic to believe that an international body such as this would be capable of coming to a fair and ecumenical conclusion and imposing it on every nation.”

Eco: The Last Flowering of Philosophic Languages, 2

Giovan Giuseppe Matraja, Genigrafia italiana, 1831

Giovanni Giuseppe Matraja, Genigrafia italiana, 1831. Original held at the University of Illinois at Urbana-Champaign, with a glorious eBook format posted by the Hathitrust and GoogleBooks among others. 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. 

Vismes was not the only one to fall foul of this seemingly elementary snare. In 1831 Father Giovan Giuseppe Matraja published his Genigrafia italiana, which is nothing other than a polygraphy with five (Italian) dictionaries, one for nouns, one for verbs, one for adjectives, one for interjections and one for adverbs.

Since the five dictionaries account for only 15,000 terms, Matraja adds another dictionary that lists 6,000 synonyms. His method managed to be both haphazard and laborious: Matraja divided his terms into a series of numbered classes each containing 26 terms, each marked by an alphabetical letter: thus A1 means “hatchet,” A2 means “hermit,” A1000 means “encrustation,” A360 means “sand-digger,” etc.

Even though he had served as a missionary in South America, Matraja was still convinced that all cultures used the same system of notions. He believed that western languages (all of which he seemed to imagine were derived from Latin grammar) might perfectly well serve as the basis for another language, because, by a special natural gift, all peoples used the same syntactic structures when speaking–especially American Indians.

In fact, he included a genigraphical translation of the Lord’s Prayer comparing it with versions in twelve other languages including Nahuatl, Chilean and Quechua.

In 1827 François Soudre invented the Solresol (Langue musicale universelle, 1866). Soudre was also persuaded that the seven notes of the musical scale composed an alphabet comprehensible by all the peoples of the world, because the notes are written in the same way in all languages, and could be sung, recorded on staves, represented with special stenographic signs, figured in Arabic numerals, shown with the seven colors of the spectrum, and even indicated by the touch of the fingers of the right and left hands–thus making their representation comprehensible even for the deaf, dumb and blind.

It was not necessary that these notes be based on a logical classification of ideas. A single note expresses terms such as “yes” (musical si, or B) and “no” (do, or C); two notes express pronouns (“mine” = redo, “yours” = remi); three notes express everyday words like “time” (doredo) or “day” (doremi).

The initial notes refer to an encyclopedic class. Yet Soudre also wished to express opposites by musical inversion (a nice anticipation of a twelve-tone music procedure): thus, if the idea of “God” was naturally expressed by the major chord built upon the tonic, domisol, the idea of “Satan” would have to be the inversion, solmido.

Of course, this practice makes nonsense of the rule that the first letter in a three-note term refers to an encyclopedic class: the initial do refers to the physical and moral qualities, but the initial sol refers back to arts and sciences (and to associate them with Satan would be an excess of bigotry).

Besides the obvious difficulties inherent in any a priori language, the musical language of Soudre added the additional hurdle of requiring a good ear. We seem in some way to be returning to the seventeenth century myth of the language of birds, this time with less glossolalic grace, however, and a good deal more pure classificatory pedantry.

Couturat and Leau (1903: 37) awarded to the Solresol the encomium of being “the most artificial and most impracticable of all the a priori languages.” Even its number system is inaccessible; it is based on a hexadecimal system which, despite its claims to universality, still manages to indulge in the French quirk of eliminating names for 70 and 90.

Yet Soudre labored for forty-five years to perfect his system, obtaining in the meantime testimonials from the Institut de France, from musicians such as Cherubini, from Victor Hugo, Lamartine and Alexander von Humboldt; he was received by Napoleon III; he was awarded 10,000 francs at the Exposition Universale in Paris in 1855 and the gold medal at the London Exposition of 1862.

Let us neglect for the sake of brevity the Système de langue universelle of Grosselin (1836), the Langue universelle et analytique of Vidal (1844), the Cours complet de langue universelle by Letellier (1832-55), the Blaia Zimandal of Meriggi (1884), the projects of so distinguished a philosopher as Renouvier (1885), the Lingualumina of Dyer (1875), the Langue internationale étymologique of Reimann (1877), the Langue naturelle of Maldant (1887), the Spokil of Dr. Nicolas (1900), the Zahlensprache of Hilbe (1901), the Völkerverkehrsprache of Dietrich (1902), and the Perio of Talundberg (1904).

We will content ourselves with a brief account of the Projet d’une langue universelle of Sotos Ochando (1855). Its theoretical foundations are comparatively well reasoned and motivated; its logical structure could not be of a greater simplicity and regularity; the project proposes–as usual–to establish a perfect correspondence between the order of things signified and the alphabetical order of the words that express them.

Unfortunately–here we go again–the arrangement is empirical: A refers to inorganic material things, B to the liberal arts, C to the mechanical arts, D to political society, E to living bodies, and so forth.

With the addition of the morphological rules, one generates, to use the mineral kingdom as an example, the words Ababa for oxygen, Ababe for hydrogen, Ababi for nitrogen, Ababo for sulphur.

If we consider that the numbers from one to ten are siba, sibe, sibi, sibo, sibu, sibra, sibre, sibri, sibro, and sibru (pity the poor school children having to memorize their multiplication tables), it is evident that words with analogous meanings are all going to sound the same.

This makes the discrimination of concepts almost impossible, even if the formation of names follows a criterion similar to that of chemistry, and the letters stand for the components of the concept.

The author may claim that, using his system, anyone can learn over six million words in less than an hour; yet as Couturat and Leau remark (1903: 69), learning a system that can generate six million words in an hour is not the same as memorizing, recognizing, six million meanings.

The list could be continued, yet towards the end of the nineteenth century, news of the invention of a priori languages was becoming less a matter for scientific communications and more one for reports on eccentric fellows–from Les fous littéraires by Brunet in 1880 to Les fous littéraires by Blavier in 1982.

By now, the invention of a priori languages, other than being the special province of visionaries of all lands, had become a game (see Bausani 1970 and his language Markuska) or a literary exercise (see Yaguello 1984 and Giovannoli 1990 for the imaginary languages of science fiction).

Eco:Eighteenth Century Projects

Telemaque_1st_page

François Fénelon (1651-1715), Telemachus, or the first page of the first book of Les Aventures de Télémaque, first published anonymously in 1699, and translated into English in London in 1715. 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.  

“Even under the weight of the Enlightenment critique, the dream of the perfect language refused to die. In 1720 there appeared a “Dialogue sur la facilité qu’il y auroit d’établir un Caractère Universel qui seroit commun à toutes les Langues de l’Europe, et intelligible à différens Peuples, qui le liroient chacun dans la propre Langue” (in the Journal littéraire de l’anné 1720).

As the title itself suggests, the project was for a polygraphy, in the sense we saw in Kircher, and, at most, it is worthy of note in that its attempt to include a contracted grammar points the way to future developments.

In any case, the proposal is distinguished by including an appeal, by the anonymous author, for a commission which would develop the project and for a prince who would impose its adoption.

Such an appeal “cannot help but remind us of a possibility, which must have seemed evident in the year 1720, that a phase of stability for Europe was about to open, and that, consequently, sovereigns might be expected to be more willing to patronize linguistic and intellectual experiments” (cf. Pellerey 1992a: 11).

In his article on “Langue” in the Encyclopédie, even a rationalist like Beauzée had to concede that, since it would be difficult to come to an agreement over a new language, and an international language still seemed to him to be necessary, Latin had to remain the most reasonable candidate.

For their part, the empiricists among the encyclopedists felt duty-bound to consider the idea of a universal language, too. As a sort of coda to the article on “Langue,” Joachim Faiguet wrote four pages on a project for a langue nouvelle. Couturat and Leau (1903: 237) consider this as representing a first attempt at overcoming the problems inherent in the a priori languages and at sketching out an example of the a posteriori languages we will be discussing in the next chapter.

As his model, Faiguet took a natural language–French. He formed his lexicon on French roots, and concentrated on the delineation of a simplified and regularized grammar, or a “laconic” grammar.

Following the authors in the previous century, Faiguet eliminated those grammatical categories that seemed to him redundant: he suppressed the articles, substituted flexions with prepositions (bi for the genitive, bu for the dative, and de and po for the ablative), transformed adjectives (indeclinable) into adverbial forms, standardized all plurals (always expressed by an s); he simplified verb conjugations, making them invariable in number and person, adding endings that designated tenses and modes (I give, you give, he gives became Jo dona, To dona, Lo dona); the subjunctive was formed by adding an r to the stem, the passive by the indicative plus sas (meaning to be: thus to be given became sas dona).

Faiguet’s language appears as wholly regular and without exceptions; every letter or syllable used as endings had a precise and unique grammatical significance. Still, it is parasitic on French in a double sense: not only is it a “laconicized” French at the expression-level; it is French that supplies the content-level as well. Thus Faiguet’s was little less than a sort of easy-to-manage Morse code (Bernadelli 1992).

The most important projects for a priori languages in the eighteenth century were those of Jean Delormel (Projet d’une langue universelle, 1795), of Zalkind Hourwitz (Polygraphie, ou l’art de correspondre à l’aide d’un dictionaire dans toutes les langues, même celles dont on ne possède pas seulement les lettres alphabétiques, 1800), and of Joseph de Maimieux (Pasigraphie, 1797).

As can be seen, De Maimieux’s project was a pasigraphy–that is, a universal written language. Since, however, in 1799 this same author had also formulated a pasilalie–adding rules for pronouncing his language–his project can be considered as an a priori language.

For its part, Hourwitz’s project was for a polygraphy, too–even though he seemed unaware that his was by no means the first project of this type. Still, in its structure, Hourwitz’s polygraphy was an a priori language.

Although all three projects still followed the principles laid down in the seventeenth century tradition, they were different in three fundamental ways: their purposes, the identification of their primitives, and their grammars.

Delormel presented his scheme to the Convention; De Maimieux published his Pasigraphie under the Directory; Hourwitz wrote under the Consulate: every religious motivation had disappeared.

De Maimieux spoke of communication between European nations, between Europeans and Africans, of providing a means of checking the accuracy of translations, of speeding up diplomacy and civil and military undertakings, of a new source of income for teachers, writers and publishers who should “pasigraphize” books written in other languages.

Hourwitz added to this list other purely practical considerations, such as the advantages in the relations between doctors and patients or in courtroom procedures. As one symptom of a new political and cultural atmosphere, instead of using the Lord’s Prayer as a sample translation, Hourwitz chose the opening of Fénelon’s Aventures de Télemaque–a work which, despite its moralizing bent, was still a piece of secular literature portraying pagan gods and heroes.

The revolutionary atmosphere imposed, or at least encouraged, considerations of fraternité. Thus Delormel could claim that:

“in this revolutionary moment, when the human spirit, regenerating itself among the French people, leaps forward with renewed energy, is it too much to hope that perhaps [ . . . ] we might offer to the public a new language as well, a language that facilitates new discoveries by bringing students of various nations together, a language that serves as a common term for all languages, a language easy to grasp even for men with but a slight aptitude for instruction, a language, in short, which will soon make out of all the people of mankind a single, grand family? [ . . . ] The Light of Reason brings men together and thus reconciles them; this language, by facilitating its communication, will help to propagate that Light.” (pp. 48-50).

Each of the authors was aware of the objections made by the authors of the Encyclopédie; thus the a priori languages which they proposed were all ordered according to an encyclopedia-like structure, easy to understand and designed upon the model of the eighteenth century system of knowledge.

Gone was the grandiose pansophist afflatus that animated baroque encyclopedias; the criterion of selection was rather that of Leibniz: the inventors of the languages behaved as if they were conscientious librarians hoping to make consultation as easy as possible, without worrying whether or not their ordering corresponded to the theater of the world.

Absent as well was the search for “absolute” primitives; the fundamental categories were the large-scale divisions of knowledge; under these were listed dependent notions attached as sub-headings.

Delormel, for example, assigned different letters of the alphabet to several encyclopedic classes in a way reminiscent not so much of Wilkins as of the anonymous Spaniard–grammar, art of speech, states of things, correlatives, useful, pleasurable, moral, sensations, perception and judgement, passions, mathematics, geography, chronology, physics, astronomy, minerals, etc.”

Eco: Blind Thought, 2

Wittgenstein, Ludwig

Ludwig Wittgenstein (1899-1951), portrait by Moritz Nähr (1859-1945), 1930, held by the Austrian National Library under Accession Number Pf 42.805: C (1). 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 70 years or less. 

“As Leibniz observed in the Accessio ad arithmeticum infinitorum of 1672 (Sämtliche Schriften und Briefen, iii/1, 17), when a person says a million, he does not represent mentally to himself all the units in that number. Nevertheless, calculations performed on the basis of this figure can and must be exact.

Blind thought manipulates signs without being obliged to recognize the corresponding ideas. For this reason, increasing the power of our minds in the manner that the telescope increases the power of our eyes, it does not entail an excessive effort.

“Once this has been done, if ever further controversies should arise, there should be no more reason for disputes between two philosophers than between two calculators. All that will be necessary is that, pen in hand, they sit down together at a table and say to each other (having called, if they so please, a friend) “let us calculate.” (In Gerhardt 1875: VII, 198ff).

Leibniz’s intention was thus to create a logical language, like algebra, which might lead to the discovery of unknown truths simply by applying syntactical rules to symbols. When using this language, it would no more be necessary, moreover, to know at every step what the symbols were referring to than it was necessary to know the quantity represented by algebraic symbols to solve an equation.

Thus for Leibniz, the symbols in the language of logic no longer stood for concrete ideas; instead, they stood in place of them. The characters “not only assist reasoning, they substitute for it.” (Couturat 1901: 101).

Dascal has objected (1978: 213) that Leibniz did not really conceive of his characteristica as a purely formal instrument apparatus, because symbols in his calculus are always assigned an interpretation. In an algebraic calculation, he notes, the letters of the alphabet are used freely; they are not bound to particular arithmetical values.

For Leibniz, however, we have seen that the numerical values of the characteristic numbers were, so to speak, “tailored” to concepts that were already filled with a content–“man,” “animal,” etc.

It is evident that, in order to demonstrate that “man” does not contain “monkey,” the numerical values must be chosen according to a previous semantic decision. It would follow that what Leibniz proposed was really a system both formalized and interpreted.

Now it is true that Leibniz’s posterity elaborated such systems. For instance, Luigi Richer (Algebrae philosophicae in usum artis inveniendi specimen primum, “Melanges de philosophie et de mathématique de la Societé Royale de Turin,” 1761: II/3), in fifteen short and extremely dry pages, outlined a project for the application of algebraic method to philosophy, by drawing up a tabula characteristica containing a series of general concepts (such as aliquid, nihil, contingens, mutabile) and assigning to each a conventional sign.

The system of notation, semicircles orientated in various ways, makes the characters hard to distinguish from one another; still, it was a system of notation that allowed for the representation of philosophical combinations such as “This Possible cannot be Contradictory.”

This language is, however, limited to abstract reasoning, and, like Lull, Richer did not make full use of the possibilities of combination in his system as he wished to reject all combinations lacking scientific utility (p. 55).

Towards the end of the eighteenth century, in a manuscript dating 1793-4, we also find Condorcet toying with the idea of a universal language. His text is an outline of mathematical logic, a langue des calculs, which identifies and distinguishes intellectual processes, expresses real objects, and enunciates the relations between the expressed objects and the intellectual operations which discover the enunciated relations.

The manuscript, moreover, breaks off at precisely the point where it had become necessary to proceed to the identification of the primitive ideas; this testifies that, by now, the search for perfect languages was definitively turning in the direction of a logico-mathematical calculus, in which no one would bother to draw up a list of ideal contents but only to prescribe syntactic rules (Pellerey 1992a: 193ff).

We could say that Leibniz’s characteristica, from which Leibniz had also hoped to derive metaphysical truths, is oscillating between a metaphysical and ontological point of view, and the idea of designing a simple instrument for the construction of deductive systems (cf. Barone 1964: 24).

Moreover, his attempts oscillate between a formal logic (operating upon unbound variables) and what will later be the project of many contemporary semantic theories (and of artificial intelligence as well), where syntactic rules of a mathematical kind are applied to semantic (and therefore interpreted) entities.

But Leibniz ought to be considered the forerunner of the first, rather than of the second, line of thought.

The fundamental intuition that lies behind Leibniz’s proposal was that, even if the numbers were chose arbitrarily, even if it could not be guaranteed that the primitives posited for the same of argument were really primitive at all, what still guaranteed the truth of the calculus was the fact that the form of the proposition mirrored an objective truth.

Leibniz saw an analogy between the order of the world, that is, of truth, and the grammatical order of the symbols in language. Many have seen in this a version of the picture theory of language expounded by Wittgenstein in the Tractatus, according to which “a picture has logico-pictorial form in common with what it depicts” (2.2).

Leibniz was thus the first to recognize that the value of his philosophical language was a function of its formal structure rather than of its terms; syntax, which he called habitudo or propositional structure, was more important than semantics (Land 1974: 139).

“It is thus to be observed that, although the characters are assumed arbitrarily, as long as we observe a certain order and certain rule in their use, they give us results which always agree with each other. (Dialogus in Gerhardt 1875: VII, 190-3).

Something can be called an “expression” of something else whenever the structure [habitudines] subsisting in the expression corresponds to the structure of that which it wishes to express [ . . . ].

From the sole structure of the expression, we can reach the knowledge of the properties of the thing expressed [ . . . ] as long as there is maintained a certain analogy between the two respective structures.” (Quid sit idea in Gerhardt 1875: VII, 263-4).

What other conclusion could the philosopher of preestablished harmony finally have reached?”

Eco: The Problem of the Primitives

Gottfried Wilhelm von Leibniz, Dissertatio de Arte Combinatoria, frontispiece

Gottfried Wilhelm von Leibniz (1646-1716), Dissertatio de Arte Combinatoria, frontispiece, Dissertation on the Art of Combinations or On the Combinatorial Art, Leipzig, 1666. 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.

“What did Leibniz’s ars combinatoria have in common with the projects for universal languages? The answer is that Leibniz had long wondered what would be the best way of providing a list of primitives and, consequently, of an alphabet of thoughts or of an encyclopedia.

In his Initia et specimina scientiae generalis (Gerhardt 1875: VII, 57-60) Leibniz described an encyclopedia as an inventory of human knowledge which might provide the material for the art of combination.

In the De organo sive arte magna cogitandi (Couturat 1903: 429-31) he even argued that “the greatest remedy for the mind consists in the possibility of discovering a small set of thoughts from which an infinity of other thoughts might issue in order, in the same way as from a small set of numbers [the integers from 1 to 10] all the other numbers may be derived.”

It was in this same work that Leibniz first made hints about the combinational possibilities of a binary calculus.

In the Consilium de Encyclopedia nova conscribenda methodo inventoria (Gensini 1990: 110-20) he outlined a system of knowledge to be subjected to a mathematical treatment through rigorously conceived propositions. He proceeded to draw up a plan of how the sciences and other bodies of knowledge would then be ordered: from grammar, logic, mnemonics topics (sic) and so on to morals and to the science of incorporeal things.

In a later text on the Termini simpliciores from 1680-4 (Grua 1948: 2, 542), however, we find him falling back to a list of elementary terms, such as “entity,” “substance” and “attribute,” reminiscent of Aristotle’s categories, plus relations such as “anterior” and “posterior.”

In the Historia et commendatio linguae characteristicae we find Leibniz recalling a time when he had aspired after “an alphabet of human thoughts” such that “from the combination of the letters of this alphabet, and from the analysis of the vocables formed by these letters, things might be discovered and judged.”

It had been his hope, he added, that in this way humanity might acquire a tool which would augment the power of the mind more than telescopes and microscopes had enlarged the power of sight.

Waxing lyrical over the possibilities of such a tool, he ended with an invocation for the conversion of the entire human race, convinced, as Lull had been, that if missionaries were able to induce the idolators to reason on the basis of the calculus they would soon see that the truths of our faith concord with the truths of reason.

Immediately after this almost mystical dream, however, Leibniz acknowledged that such an alphabet had yet to be formulated. Yet he also alluded to an “elegant artifice:”

“I pretend that these marvelous characteristic numbers are already given, and, having observed certain of their general properties, I imagine any other set of numbers having similar properties, and, by using these numbers, I am able to prove all the rules of logic with an admirable order, and to show in what way certain arguments can be recognized as valid by regarding their form alone.” (Historia et commendatio, Gerhardt 1875: VII, 184ff).

In other words, Leibniz is arguing that the primitives need only be postulated as such for ease of calculation; it was not necessary that they truly be final, atomic and unanalyzable.

In fact, Leibniz was to advance a number of important philosophical considerations that led him to conclude that an alphabet of primitive thought could never be formulated. It seemed self-evident that there could be no way to guarantee that a putatively primitive term, obtained through the process of decomposition, could not be subjected to further decomposition.

This was a thought that could hardly have seemed strange to the inventor of the infinitesimal calculus:

There is not an atom, indeed there is no such thing as a body so small that it cannot be subdivided [ . . . ] It follows that there is contained in every particle of the universe a world of infinite creatures [ . . . ] There can be no determined number of things, because no such number could satisfy the need for an infinity of impressions.” (Verità prime, untitled essay in Couturat 1903: 518-23).

If no one conception of things could ever count as final, Leibniz concluded that we must use the conceptions which are most general for us, and which we can consider as prime terms only within the framework of a specific calculus.

With this, Leibniz’s characteristica breaks its link with the research into a definitive alphabet of thought. Commenting on the letter to Mersenne in which Descartes described the alphabet of thoughts as a utopia, Leibniz noted:

“Even though such a language depends upon a true philosophy, it does not depend upon its perfection. This is to say: the language can still be constructed despite the fact that the philosophy itself is still imperfect.

As the science of mankind will improve, so its language will improve as well. In the meantime, it will continue to perform an admirable service by helping us retain what we know, showing what we lack, and inventing means to fill that lack.

Most of all, it will serve to avoid those disputes in the sciences that are based on argumentation. For the language will make argument and calculation the same thing.” (Couturat 1903: 27-8).

This was not only a matter of convention. The identification of primitives cannot precede the formulation of the lingua characteristica because such a language would not be a docile instrument for the expression of thought; it is rather the calculating apparatus through which those thoughts must be found.”

Eco: Characteristica and Calculus

Gottfried Wilhelm von Leibniz, Dissertatio de Arte Combinatoria

Gottfried Wilhelm von Leibniz (1646-1716), Dissertatio de Arte Combinatoria, an excerpt from his first doctoral dissertation, Dissertation on the Art of Combinations, Leipzig, 1666. 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. 

“The theme of invention and discovery should remind us of Lull; and, in fact, Lull’s ars combinatoria was one of Leibniz’s first sources. In 1666, at the age of twenty, Leibniz composed his own Dissertatio de arte combinatoria (Gerhardt 1875: IV, 27-102). But the dream of the combinatoria was to obsess him for the rest of his life.

In his short Horizon de la doctrine humaine (in Fichant 1991), Leibniz dealt with a problem that had already troubled Father Mersenne: how many utterances, true, false or even nonsensical, was it possible to formulate using an alphabet of 24 letters?

The point was to determine the number of truths capable of expression and the number of expressions capable of being put into writing. Given that Leibniz had found words of 31 letters in Latin and Greek, an alphabet of 24 letters would produce 2432 words of 31 letters.

But what is the maximum length of an expression? Why should an expression not be as long as an entire book? Thus the sum of the expressions, true or false, that a man might read in the course of his life, imagining that he reads 100 pages a day and that each page contains 1,000 letters, is 3,650,000,000.

Even imagining that this man can live one thousand years, like the legendary alchemist Artephius, it would still be the case that “the greatest expressible period, or the largest possible book that a man can read, would have 3,650,000,000,000 [letters], and the number of truths, falsehoods, or sentences expressible–that is, readable, regardless of pronounceability or meaningfulness–will be 24365,000,000,001 – 24/23 [letters].”

We can imagine even larger numbers. Imagine our alphabet contained 100 letters; to write the number of letters expressible in this alphabet we would need to write a 1 followed by 7,300,0000,000,000 (sic) zeros. Even to write such a number it would take 1,000 scribes working for approximately 37 years.

Leibniz’s argument at this point is that whatever we take the number of propositions theoretically capable of expression to be–and we can plausibly stipulate more astronomical sums than these–it will be a number that vastly outstrips the number of true or false expressions that humanity is capable of producing or understanding.

From such a consideration Leibniz concluded paradoxically that the number of expressions capable of formulation must always be finite, and, what is more, that there must come a moment at which humanity would start to enunciate them anew.

With this thought, Leibniz approaches the theme of the apochatastasis or of universal reintegration–what we might call the theme of the eternal return.

This was a line of speculation more mystical than logical, and we cannot stop to trace the influences that led Leibniz to such fantastic conclusions.

It is plain, however, that Leibniz has been inspired by Lull and the kabbala, even if Lull’s own interest was limited to the generation of just those propositions that expressed true and certain knowledge and he thus would never have dared to enlarge his ars combinatoria to include so large a number of propositions.

For Leibniz, on the contrary, it was a fascination with the vertiginous possibilities of discovery, that is of the infinite number of expressions of which a simple mathematical calculation permitted him to conceive, that served as inspiration.

At the time he was writing his Dissertatio, Leibniz was acquainted with Kircher’s Polygraphia, as well as with the work of the anonymous Spaniard, of Becher, and of Schott (while saying that he was waiting for the long-promised Ars magna sciendi of the “immortal Kircher“).

He had yet to read Dalgarno, and Wilkins had still not published his Essay. Besides, there exists a letter from Kircher to Leibniz, written in 1670, in which the Jesuit confessed that he had not yet read Leibniz’s Dissertatio.

Leibniz also elaborated in the Dissertatio his so-called method of “complexions,” through which he might calculate, given n elements, how many groups of them, taken t at a time, irrespective of their ordering, can be ordered.

He applied this method to syllogisms before he passed to his discussion of Lull (para. 56). Before criticizing Lull for limiting the number of his elements, Leibniz made the obvious observation that Lull failed to exploit all the possibilities inherent in his combinatorial art, and wondered what could happen with variations of order, which could produce a greater number.

We already know the answer: Lull not only limited the number of elements, but he rejected those combinations that might produce propositions which, for theological and rhetorical reasons, he considered false.

Leibniz, however, was interested in a logica inventiva (para. 62) in which the play of combinations was free to produce expressions that were heretofore unknown.

In paragraph 64 Leibniz began to outline the theoretical core of his characteristica universalis. Above all, any given term needed to be resolved into its formal parts, the parts, that is, that were explicitly entailed by its definition.

These parts then had to be resolved into their own components, and so on until the process reached terms which could not, themselves, be defined–that is, the primitives. Leibniz included among them not only things, but also modes and relations.

Other terms were to be classified according to the number of prime terms they contained: if they were composed from 2 prime terms, they were to be called com2nations; if from 3 prime terms, com3nations, and so forth. Thereby a hierarchy of classes of increasing complexity could be created.

Leibniz returned to this argument a dozen years later, in the Elementa characteristicae universalis. Here he was more generous with his examples. If we accept the traditional definition of man as “rational animal,” we might consider man as a concept composed of “rational” and “animal.”

We may assign numbers to these prime terms: animal = 2, and rational = 3. The composite concept of man can be represented as the expression 2 * 3, or 6.

For a proposition to be true, if we express fractionally the subject-predicate (S/P) relationship, the number which corresponds to the subject must be exactly divisible by the number which corresponds to the predicate.

Given the preposition “all men are animals,” the number for the subject (men), is 6; the number for animals is 2; the resulting fraction is 6/2 = 3. Three being an integer, consequently, the preposition is true.

If the number for monkey were 10, we could demonstrate the falsity of either the proposition “all men are monkeys” or “all monkeys are men:” “the idea of monkey does not contain the idea of man, nor, vice versa, does the idea of the latter contain the former, because neither can 6 be exactly divided by 10, nor 10 by 6” (Elementa, in Couturat 1903: 42-92). These were principles that had all been prefigured in the Dissertatio.

Eco: From Leibniz to the Encyclopédie

Gottfried_Wilhelm_Leibniz_c1700

Johann Friedrich Wentzel (1670-1729), Gottfried Wilhelm Leibniz (1646-1716), circa 1700. 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. 

“In 1678 Leibniz composed a lingua generalis (in Couturat 1903). After decomposing all of human knowledge into simple ideas, and assigning a number to each, Leibniz proposed a system of transcription for these numbers in which consonants stood for integers and vowels for units, tens and powers of ten:

Umberto Eco, The Search for the Perfect Language, p. 270

Umberto Eco, The Search for the Perfect Language, p. 270. 

In this system, the figure 81,374, for example, would be transcribed as mubodilefa. In fact, since the relevant power of ten is shown by the following vowel rather than by the decimal place, the order of the letters in the name is irrelevant: 81,374 might just as easily be transcribed as bodifalemu.

This system might lead us to suspect that Leibniz too was thinking of a language in which the users might one day discourse on bodifalemu or gifeha (= 546) just as Dalgarno or Wilkins proposed to speak in terms of nekpot or deta.

Against this supposition, however, lies the fact that Leibniz applied himself to another, particular form of language, destined to be spoken–a language that resembled the latino sine flexione invented at the dawn of our own century by Peano.

This was a language whose grammar was drastically simplified and regularized: one declension for nouns, one conjunction for verbs, no genders, no plurals, adjectives and adverbs made identical, verbs reduced to the formula of copula + adjective.

Certainly, if my purpose were to try to delineate the entire extent of the linguistic projects undertaken by Leibniz throughout the course of his life, I would have to describe an immense philosophical and linguistically monument displaying four major aspects:

(1) the identification of a system of primitives, organized in an alphabet of thought or in a general encyclopedia;

(2) the elaboration of an ideal grammar, inspired probably by the simplifications proposed by Dalgarno, of which the simplified Latin is one example;

(3) the formulation of a series of rules governing the possible pronunciation of the characters;

(4) the elaboration of a lexicon of real characters upon which the speaker might perform calculations that would automatically lead to the formulation of true propositions.

The truth is, however, that by the end of his career, Leibniz had abandoned all research in the initial three parts of the project. His real contribution to linguistics lies in his attempts at realizing the fourth aspect.

Leibniz had little interest in the kinds of universal language proposed by Dalgarno and Wilkins, though he was certainly impressed by their efforts. In a letter to Oldenburg (Gerhardt 1875: VII, 11-5), he insisted that his notion of a real character was profoundly different from that of those who aspired to a universal writing modeled on Chinese, or tried to construct a philosophic language free from all ambiguity.

Leibniz had always been fascinated by the richness and plurality of natural languages, devoting his time to the study of their lineages and the connections between them. He had concluded that it was not possible to identify (much less to revive) an alleged Adamic language, and came to celebrate the very confusio linguarum that others were striving to eliminate (see Gensini 1990, 1991).

It was also a fundamental tenet of his monadology that each individual had a unique perspective on the world, as if a city would be represented from as many different viewpoints as the different positions of its inhabitants.

It would have been incongruous for the philosopher who held this doctrine to oblige everyone to share the same immutable grillwork of genera and species, without taking into account particularities, diversities and the particular “genius” of each natural language.

There was but one facet of Leibniz’s personality that might have induced him to seek after a universal form of communication; that was his passion for universal peace, which he shared with Lull, Cusanus and Postel.

In an epoch in which his english predecessors and correspondents were waxing enthusiastic over the prospect of universal languages destined to ease the way for future travel and trade, beyond an interest in the exchange of scientific information, Leibniz displayed a sensitivity towards religious issues totally absent even in high churchmen like Wilkins.

By profession a diplomat and court councillor, Leibniz was a political, rather than an academic, figure, who worked for the reunification of the church. This was an ecumenicism that reflected his political preoccupations; he envisioned an anti-French bloc of Spain, the papacy, the Holy Roman Emperor and the German princes.

Still, his desire for unity sprang from purely religious motives as well; church unity was the necessary foundation upon which a peaceful Europe could be built.

Leibniz, however, never thought that the main prerequisite for unity and peace was a universal tongue. Instead, he thought that the cause of peace might be better served by science, and by the creation of a scientific language which might serve as a common instrument in the discovery of truth.”
