Eco: Blind Thought, 2

Wittgenstein, Ludwig

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


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.”

Eco: John Wilkins


John Wilkins (1614-1672), An Essay Towards a Real Character and a Philosophical Language, London, John Martin, 1668. 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. 

“Already in Mercury, a book principally devoted to secret writing, published in 1641, Wilkins had begun to design a project for universal language. It was not until 1668, however, that he was ready to unveil his Essay towards a Real Character, and a Philosophical Language–the most complete project for a universal and artificial philosophical language that the seventeenth century was ever to produce.

Since “the variety of Letters is an appendix to the Curse of Babel” (p. 13), after a dutiful bow in the direction of the Hebrew language and a sketch of the evolution of languages from Babel onwards (including an examination of the Celto-Scythian hypothesis that we considered in ch. 5), and after an acknowledgment of his precursors and his collaborators in the compilation of classifications and of the final dictionary, Wilkins turned to his major task–the construction of a language founded on real characters “legible by any Nation in their own Tongue” (p. 13).

Wilkins observed that most earlier projects derived their list of characters from the dictionary of one particular language rather than drawing directly on the nature of things, and from that stock of notions held in common by all humanity.

Wilkins‘ approach required, as a preliminary step, a vast review of all knowledge to establish what these notions held in common by all rational beings really were.

Wilkins never considered that these fundamental notions might be Platonic ideas like Lull’s dignities. His list was rather based upon empirical criteria and he sought those notions to which all rational beings might either attest or, reasonably, be expected to attest: thus, if everybody agrees on the idea of a God, everybody would likewise agree on the botanical classification supplied to him by his colleague John Ray.

In reality, the image of the universe that Wilkins proposed was the one designed by the Oxonian culture of his time. Wilkins never seriously wondered whether other cultures might have organized the world after a different fashion, even though his universal language was designed for the whole of humanity.

The Tables and the Grammar

In appearance the classification procedure chosen by Wilkins was akin to the method of the Porphyrian Tree of Aristotelian tradition. Wilkins constructed a table of 40 major genera (see figure 12.1) subdivided into 251 characteristic differences.

Umberto Eco, The Search for the Perfect Language, Figure 12.1, p. 240

Umberto Eco, The Search for the Perfect Language, Figure 12.1, p. 240. 

Umberto Eco, The Search for the Perfect Language, Figure 12.1-2, p. 241

Umberto Eco, The Search for the Perfect Language, Figure 12.1-2, p. 241.

From these he derived 2,030 species, which appear in pairs. Figure 12.2 provides a simplified example of the procedure: starting from the major genus of Beasts, after having divided them into viviparous and oviparous, and after having subdivided the viviparous ones into whole footed, cloven footed and clawed, Wilkins arrives at the species Dog / Wolf.

Umberto Eco, The Search for the Perfect Language, Figure 12.2, p. 242

Umberto Eco, The Search for the Perfect Language, Figure 12.2, p. 242.

I might add parenthetically that Wilkins‘ tables occupy a full 270 pages of his ponderous folio, and hope that the reader will excuse the summary nature of the examples which follow.

After presenting the tables, which supposedly design the whole knowable universe, Wilkins turned his attention to his natural (or philosophical) grammar in order to establish morphemes and the markers for derived terms, which can permit the generation, from the primitives, of declensions, conjugations, suffixes and so on.

Such a simplified grammatical machinery should thus allow the speaker to articulate discourses, as well as to produce the periphrases through which terms from a natural language might be defined entirely through the primitives of the artificial one.

Having reached this stage, Wilkins was able to present his language of real characters. In fact, it splits into two different languages: (1) the first is an ideogrammatic form of writing, vaguely Chinese in aspect, destined to appear in print but never to be pronounced; (2) the second is expressed by alphabetic characters and is intended to be pronounced.

It is possible to speak properly of two separate languages because, even though the pronounceable characters were constructed according to the same compositional principle as the ideograms, and obey the same syntax, they are so different that they need to be learned apart.”

Eco: The English Debate on Character and Traits


Anonymous, Gerardus Johannes Vossius (1577-1649), 1636, inscribed (verso): GERH.JOH. VOSSIUS CANONICUS CANTUARIENSIS PROFESSOR HISTORIARII AMSTELO…AET LX Ao 1636. Held at the Universiteitsmuseum Amsterdam. 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 1654 John Webster wrote his Academiarum examen, an attack on the academic world, which had allegedly given an insufficient amount of attention to the problem of universal language.

Like many of this English contemporaries, Webster was influenced by Comenius‘ propaganda for a universal language. He foresaw the birth of a “Hieroglyphical, Emblematical, Symbolical, and Cryptographical learning.”

Describing the general utility of algebraic and mathematical signs, he went on to note that “the numerical notes, which we call figures and ciphers, the Planetary Characters, the marks for minerals, and many other things in Chymistry, though they be alwaies the same and vary not, yet are understood by all nations in Europe, and when they are read, every one pronounces them in their own Countrey’s language and dialect.” (pp. 24-5).

Webster was not alone; other authors were taking up and elaborating ideas which had first originated with Bacon. Another writer championing universal characters was Gerhard Vossius in De arte grammatica, 1635 (1.41).

Nevertheless, for the men from whose ranks the Royal Society would later be formed, Webster’s demand for research in hieroglyphic and emblematic characters sounded too much like Father Kircher’s Egyptian linguistics.

In effect, Webster was indeed thinking of a language of nature in opposition to the institutionalized language of men (see Formigari 1970: 37).

Responding to Webster, in another pamphlet, also published in 1654 (Vindiciae academiarum, to which Wilkins himself added an introduction), Seth Ward denounced the mystic propensities of his opponent (see Slaughter 1982: 138ff).

Ward made no objection to the idea of the real character as such, provided that it was constructed upon the algebraic model invented by Viète in the sixteenth century and elaborated by Descartes, where letters of the alphabet stand for mathematical quantities.

It is, however, evident that what Ward thought of was not what Webster had in mind.

Ward argued that only the real character of which he spoke could be termed as “a naturall Language and would afford that which the Cabalists and Rosycrucians have vainely sought for in the Hebrew” (p. 22).

In his introduction Wilkins went even further: Webster, he wrote, was nothing but a credulous fanatic. Even in his Essay, which we will soon discuss, Wilkins could not resist shooting, in his introduction, indignant darts in Webster’s direction without naming him directly.

In spite of all this, however, the projects of the religious mystics did have something in common with those of the “scientists.” In that century the play of reciprocal influence was very complex and many have detected relationships between Lullists or Rosicrucians and the inventors of philosophical languages (see Ormsby-Lennon 1988; Knowlson 1975; and, of course, Yates and Rossi).

Nevertheless, in contrast to the long tradition of the search for the lost language of Adam, the position of Ward, with the aid of Wilkins, was entirely secular.

This is worth emphasizing: there was no longer any question of discovering the lost language of humanity; the new language was to be a new and totally artificial language, founded upon philosophic principles, and capable of realizing, by rational means, that which the various purported holy languages (always dreamt of, never really rediscovered) had sought but failed to find.

In every one of the holy and primordial languages we have so far considered, at least in the way they were presented, there was an excess of content, never completely circumscribable, in respect of expression.

By contrast, the search was now for a scientific or philosophical language, in which, by an unprecedented act of impositio nominum, expression and content would be locked in permanent accord.

Men such as Ward and Wilkins thus aimed at being the new Adam; it was this that turned their projects into a direct challenge to the older tradition of mystic speculation. In the letter to the reader that introduced the Essay, Wilkins writes:

“This design would likewise contribute much to the clearing of some of our modern differences in Religion, by unmasking many wild errors, that shelter themselves under the disguise of affected phrases; which being Philosophically unfolded, and rendered according to the genuine and natural importance of Words, will appear to be inconsistencies and contradictions. (B1r).”

This was nothing less than a declaration of war on tradition, a promise of a different species of therapy that would finally massage out the cramps in language; it is the first manifestation of that skeptical-analytic current of thought, exquisitely British, that, in the twentieth century, would use linguistic analysis as an instrument for the confutation of metaphysics.

Despite the persistence of the Lullian influences, there can be no doubt that, in order to realize their project, British philosophers paid close attention to Aristotle’s system of classification.

The project of Ward is an example. It was not enough simply to invent real characters for the new language; it was necessary also to develop a criterion that would govern the primitive features that would compose these characters:

“All Discourses being resolved in sentences, these into words, words signifying either simple notions or being resolvable into simple notions, it is manifest, that if all the sorts of simple notions be found out, and have Symboles assigned to them, those will be extremely few in respect of the other [ . . . ] the reason of their composition easily known, and the most compounded ones at once will be comprehended [ . . . ] so to deliver the nature of things. (Vindiciae, 21).”

Eco: Dee’s Magic Language


Florence Estienne Méric Casaubon (1599-1671), A True and Faithful Relation of what Passed for Many Yeers between Dr. John Dee [ . . . ] and Some Spirits, London, 1659. 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 his Apologia compendiaria (1615) Fludd noted that the Rosicrucian brothers practiced that type of kabbalistic magic that enabled them to summon angels. This is reminiscent of the steganography of Trithemius. Yet it is no less reminiscent of the necromancy of John Dee, a man whom many authors considered the true inspirer of Rosicrucian spirituality.

In the course of one of the angelic colloquies recorded in A True and Faithful Relation of what Passed for Many Yeers between Dr. John Dee [ . . . ] and Some Spirits (1659: 92), Dee found himself in the presence of the Archangel Gabriel, who wished to reveal to him something about the nature of holy language.

When questioned, however, Gabriel simply repeated the information that the Hebrew of Adam, the language in which “every word signifieth the quiddity of the substance,” was also the primal language–a notion which, in the Renaissance, was hardly a revelation.

After this, in fact, the text continues, for page after page, to expatiate on the relations between the names of angels, numbers and secrets of the universe–to provide, in short, another example of the pseudo-Hebraic formulae which were the stock in trade of the Renaissance magus.

Yet it is perhaps significant that the 1659 Relation was published by Meric Casaubon, who was later accused of partially retrieving and editing Dee’s documents with the intention of discrediting him.

There is nothing, of course, surprising in the notion that a Renaissance magus invoked spirits; yet, in the case of John Dee, when he gave us an instance of cipher, or mystic language, he used other means.

In 1564, John Dee wrote the work upon which his contemporary fame rested–Monas hieroglyphica, where he speaks of a geometrical alphabet with no connection to Hebrew. It should be remembered that Dee, in his extraordinary library, had many of Lull’s manuscripts, and that many of his kabbalistic experiments with Hebrew characters in fact recall Lull’s use of letters in his art of combination (French 1972: 49ff).

Dee’s Monas is commonly considered a work of alchemy. Despite this, the network of alchemical references with which the book is filled seems rather intended to fulfill a larger purpose–that of explicating the cosmic implications deriving from Dee’s fundamental symbol, the Monad, based upon circles and straight lines, all generated from a single point.


John Dee (1527-1609), Monas hieroglyphica, 1564, held in the Bibliothèque nationale de France. The Monad is the symbol at the heart of the illustration labeled Figure 8.1 in Eco’s  The Search for the Perfect Language, Oxford, 1995, p. 186.

In this symbol (see figure 8.1), the main circle represented the sun that revolves around its central point, the earth, and in its upper part was intersected by a semi-circle representing the moon.

Both sun and moon were supported on an inverted cross which represented both the ternary principle–two straight lines which intersect plus their point of intersection–and the quaternary principle–the four right angles formed at the intersections of the two lines.

The sum of the ternary and quaternary principles constituted a further seven-fold principle, and Dee goes even on to squeeze an eight-fold principle from the diagram.

By adding the first four integers together, he also derives a ten-fold principle. By such a manipulatory vertigo Dee then derives the four composite elements (heat and cold, wet and dry) as well as other astrological revelations.

From here, through 24 theorems, Dee makes his image undergo a variety of rotations, decompositions, inversions and permutations, as if it were drawing anagrams from a series of Hebrew letters.

Sometimes he considers only the initial aspects of his figure, sometimes the final one, sometimes making numerological analyses, submitting his symbol to the kabbalistic techniques of notariqon, gematria, and temurah.

As a consequence, the Monas should permit–as happens with every numerological speculation–the revelation of the whole of the cosmic mysteries.

However, the Monad also generates alphabetic letters. Dee was emphatic about this in the letter of dedication with which he introduced his book. Here he asked all “grammarians” to recognize that his work “would explain the form of the letters, their position and place in the alphabetical order, and the relations between them, along with their numerological values, and many other things concerning the primary Alphabet of the three languages.”

This final reference to “the three languages” reminds us of Postel (whom Dee met personally) and of the Collège des Trois Langues at which Postel was professor. In fact, Postel, to prove that Hebrew was the primal language in his 1553 De originibus, had observed that every “demonstration of the world” comes from point, line and triangle, and that sounds themselves could be reduced to geometry.

In his De Foenicum literis, he further argued that the invention of the alphabet was almost contemporary with the spread of language (on this point see many later kabbalistic speculations over the origins of language, such as Thomas Bang, Caelum orientis, 1657: 10).

What Dee seems to have done is to take the geometrical argument to its logical conclusion. He announced in his dedicatory letter that “this alphabetic literature contains great mysteries,” continuing that “the first Mystic letters of Hebrews, Greeks, and Romans were formed by God and transmitted to mortals [ . . . ] so that all the signs used to represent them were produced by points, straight lines, and circumferences of circles arranged by an art most marvelous and wise.”

When he writes a eulogy of the geometrical properties of the Hebrew Yod, one is tempted to think of the Dantesque I; when he attempts to discover a generative matrix from which language could be derived, one thinks of the Lullian Ars.

Dee celebrates his procedure for generating letters as a “true Kabbalah [ . . . ] more divine than grammar itself.”

These points have been recently developed by Clulee (1988: 77-116), who argues that the Monas should be seen as presenting a system of writing, governed by strict rules, in which each character is associated with a thing.

In this sense, the language of Monas is superior to the kabbala, for the kabbala aims at the interpretation of things only as they are said (or written) in language, whereas the Monas aims directly at the interpretation of things as they are in themselves. Thanks to its universality, moreover, Dee can claim that his language invents or restores the language of Adam.

According to Clulee, Dee’s graphic analysis of the alphabet was suggested by the practice of Renaissance artists of designing alphabetical letters using the compass and set-square.

Thus Dee could have thought of a unique and simple device for generating both concepts and all the alphabets of the world.

Neither traditional grammarians nor kabbalists were able to explain the form of letters and their position within the alphabet; they were unable to discover the origins of signs and characters, and for this reason they were uncapable (sic) to retrieve that universal grammar that stood at the bases of Hebrew, Greek and Latin.

According to Clulee, what Dee seems to have discovered was an idea of language “as a vast, symbolic system through which meanings might be generated by the manipulation of symbols” (1988: 95).

Such an interpretation seems to be confirmed by an author absent from all the bibliographies (appearing, to the best of my knowledge, only in Leibniz’s Epistolica de historia etymologica dissertatio of 1717, which discusses him in some depth).

This author is Johannes Petrus Ericus, who, 1697, published his Anthropoglottogonia sive linguae humanae genesis, in which he tried to demonstrate that all languages, Hebrew included, were derived from Greek.

In 1686, however, he had also published a Principium philologicum in quo vocum, signorum et punctorum tum et literarum massime ac numerorum origo. Here he specifically cited Dee’s Monas Hieroglyphica to derive from that matrix the letters of all alphabets (still giving precedence to Greek) as well as all number systems.

Through a set of extremely complex procedures, Ericus broke down the first signs of the Zodiac to reconstruct them into Dee’s Monad; he assumed that Adam had named each animal by a name that reproduced the sounds that that each emitted; then he elaborated a rather credible phonological theory identifying classes of letters such as “per sibilatione per dentes,” “per tremulatione labrorum,” “per compressione labrorum,” “per contractione palati,” “per respiratione per nares.”

Ericus concluded that Adam used vowels for the names of the beasts of the fields, and mutes for the fish. This rather elementary phonetics also enabled Ericus to deduce the seven notes of the musical scale as well as the seven letters which designate them–these letters being the basic elements of the Monas.

Finally, he demonstrated how by rotating this figure, forming, as it were, visual anagrams, the letters of all other alphabets could be derived.

Thus the magic language of the Rosicrucians (if they existed, and if they were influenced by Dee) could have been a matrix able to generate–at least alphabetically–all languages, and, therefore, all the wisdom of the world.

Such a language would have been more than a universal grammar: it would have been a grammar without syntactic structures, or, as Demonet (1992: 404) suggests, a “grammar without words,” a silent communication, close to the language of angels, or similar to Kircher’s conception of hieroglyphs.

Thus, once again, this perfect language would be based upon a sort of communicative short-circuit, capable of revealing everything, but only if it remained initiatically secret.”

Eco: The Kircherian Ideology


Athanasius Kircher (1602-80), Egyptian pyramids by Gioseffo Petrucci, Prodromo apologetico alli studi chiercheriani, Amsterdam, 1677, reprinted from Sphinx Mystagoga, a selection of images related to Athanasius Kircher in the Stanford University Archives, curated by Michael John Gorman, 2001. 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.

“It would be idle to hold Kircher responsible for his inability to understand the nature of hieroglyphic writing, for which in his time nobody had the key. Yet his ideology magnified his errors.

“Nothing can explain the duplicity of the research of Kircher better than the engraving which opens the Obeliscus Pamphilius: in this cohabit both the illuminated image of Philomatià to whom Hermes explains every mystery and the disquieting gesture of Harpocrates who turns away the profane, hidden by the shadow of the cartouche.” (Rivosecchi 1982: 57).

The hieroglyphic configurations had become a sort of machine for the inducing of hallucinations which then could be interpreted in any possible way.

Rivosecchi (1982: 52) suggests that Kircher exploited this very possibility in order to discuss freely a large number of potentially dangerous themes–from astrology to alchemy and magic–disguising his own opinions as those of an immemorial tradition, one in which, moreover, Kircher treated prefigurations of Christianity.

In the midst of this hermeneutic bulimia, however, there glimmers the exquisitely baroque temperament of Kircher at play, delighting in his taste for the great theater of mirrors and lights, for the surprising museographic collection (and one has only to think of that extraordinary Wunderkammer which was the museum of the Jesuit Collegio Romano).

Only his sensitivity to the incredible and the monstrous can explain the dedication to the Emperor Ferdinand III that opens the third volume of Oedipus:

“I unfold before your eyes, O Most Sacred Caesar, the polymorphous reign of Morpheus Hieroglyphicus. I tell of a theater in which an immense variety of monsters are disposed, and not the nude monsters of nature, but adorned by the enigmatic Chimeras of the most ancient of wisdoms so that here I trust sagacious wits will draw out immeasurable treasures for the sciences as well as no small advantage for letters.

Here there is the Dog of Bubasti, the Lion Saiticus, the Goat Mendesius, here there is the Crocodile, horrible in the yawning of its jaws, yet from whose uncovered gullet there emerges the occult meanings of divinity, of nature, and of the spirit of Ancient Wisdom espied through the vaporous play of images.

Here there are the Dipsodes thirsting for blood, the virulent Asp, the astute Icneumon, the cruel Hippopotami, the monstrous Dragons, the toad of swollen belly, the snail of twisted shell, the hairy caterpillar and the innumerable other specters which all show the admirably ordered chain which extends itself into the depths of nature’s sanctuaries.

Here is presented a thousand species of exotic things in many and varied images, transformed by metamorphosis, converted into human figures, and restored once more to themselves again in a dance of the human and the savage intertwined, and all in accordance with the artifices of the divine; and finally, there appears the divinity itself which, to say with Porphyry, scours the entire universe, ordering it with all things in a monstrous connubium; where now, sublime in its variegated face, it raises its canine cervix to reveal itself as Cenocephalus, now as the wicked Ibis, now as the Sparrow-hawk wrapped in a beaky mask.

[ . . . ] now, delighting in its virgin aspect, under the shell of the Scarab it lies concealed as the sting of the Scorpion [these descriptions carry on for four more pages] in this pantomorphic theater of nature  unfolded before our gaze, under the allegorical veil of occult meanings.”

This is the same spirit which informed the medieval taste for encyclopedias and for libri monstruorum, a genre which reappears from the Renaissance onwards under the “scientific” guise of the medical studies of Ambroise Paré, the naturalist works of Ulisse Aldrovandi, the collection of monsters of Fortunio Liceti, the Physica curiosa of Gaspar Schott.

Here it is combined, with a quality of frenzied dissymmetry that is almost Borrominian, recalling the aesthetic ideals presiding over the construction of the hydraulic grottos and mythological rocailles in the gardens of the period.

Beyond this, however, Rivosecchi has put his finger on another facet of the Kircherian ideology. In a universe placed under the sign of an ancient and powerful solar deity, the myth of Osiris had become an allegory of the troubled search for stability in the world still emerging from the aftermath of the Thirty Years War, in which Kircher was directly involved.

In this sense, we might read the dedications to Ferdinand III, which stand out at the beginning of each volume of the Oedipus, in the same light as the appeals of Postel to the French monarchy to restore harmony a century before, or as the analogous appeals of Bruno, or as Campanella’s celebration of a solar monarchy, prelude to the reign of Louis XIV, or as the calls for a golden century which we will discuss in the chapter on the Rosicrucians.

Like all the utopian visionaries of his age, the Jesuit Kircher dreamed of the recomposition of a lacerated Europe under a stable monarchy. As a good German, moreover, he repeated the gesture of Dante and turned to the Germanic, Holy Roman emperor.

Once again, as in the case of Lull, though in ways so different as to void the analogy, it was the search for a perfect language that became the instrument whereby a new harmony, not only in Europe, but across the entire planet, was to be established.

The knowledge of exotic languages, aimed not so much at recovering their original perfection, but rather at showing to the Jesuit missionaries “the method of bearing the doctrine of Christ to those cut off from it by diabolic malice” (preface to China, but also Oedipus, I, I, 396-8).

In the last of Kircher’s works, the Turris Babel, the story of the confusion of tongues is once again evoked, this time in an attempt to compose “a grandiose universal history, embracing all diversities, in a unified project of assimilation to Christian doctrine. [ . . . ]

The peoples of all the world, dispersed after the confusion, are to be called back together from the Tower of the Jesuits for a new linguistic and ideological reunification.” (Scolari 1983: 6).

In fact, hungry for mystery and fascinated by exotic languages though he was, Kircher felt no real need to discover a perfect language to reunite the world in harmony; his own Latin, spoken with the clear accents of the Counter-Reformation, seemed a vehicle perfectly adequate to transport as much gospel truth as was required in order to bring the various peoples together.

Kircher never entertained the thought that any of the languages he considered, not even the sacred languages of hieroglyphics and kabbalistic permutations, should ever again be spoken. He found in the ruins of these antique and venerated languages a garden of private delight; but he never conceived of them as living anew.

At most he toyed with the idea of preserving these languages as sacred emblems, accessible only to the elect, and in order to show their fecund impenetrability he needed elephantine commentaries.

In every one of his books, he showed himself as a baroque scholar in a baroque world; he troubled more over the execution of his tables of illustrations than over the writing (which is often wooden and repetitive).

Kircher was, in fact, incapable of thinking other than in images (cf. Rivosecchi 1982: 114). Perhaps his most lasting achievement, and certainly his most popular book, was the Ars magna lucis et umbrae of 1646.

Here he explored the visible in all its nooks and crannies, drawing from his exploration a series of scientifically valid intuitions which even faintly anticipate the invention of the techniques of photography and the cinema.”

Eco: Infinite Songs & Locutions


Giordano Bruno (1548-1600), memory wheel, De Umbris Idearum, 1582, reconstructed by Dame Frances Yates, Warburg Institute. Frances Yates wrote Giordano Bruno and the Hermetic Tradition, Chicago, 1964. 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.  

 “Between Lull and Bruno might be placed the game invented by H.P. Harsdörffer in his Matematische und philosophische Erquickstunden (1651: 516-9). He devises 5 wheels containing 264 units (prefixes, suffixes, letters and syllables).

This apparatus can generate 97,209,600 German words, including many that were still non-existent but available for creative and poetic use (cf. Faust 1981: 367). If this can be done for German, why not invent a device capable of generating all possible languages?

The problem of the art of combination was reconsidered in the commentary In spheram Ioannis de sacro bosco by Clavius in 1607. In his discussion of the four primary qualities (hot, cold, dry and wet), Clavius asked how many pairs they might form.

Mathematically, we know, the answer is six. But some combinations (like “hot and cold,” “dry and wet”) are impossible, and must be discarded, leaving only the four acceptable combinations: “Cold and dry” (earth), “hot and dry” (fire), “hot and wet” (air), “cold and wet” (water).

We seem to be back with the problem of Lull: a conventional cosmology limits the combinations.

Clavius, however, seemed to wish to go beyond these limits. He asked how many dictiones, or terms, might be produced using the 23 letters of the Latin alphabet (u being the same as v), combining them 2, 3, 4 at a time, and so on until 23.

He supplied a number of mathematical formulae for the calculations, yet he soon stopped as he began to see the immensity of the number of possible results–especially as repetitions were permissible.

In 1622, Paul Guldin wrote a Problema arithmeticum de rerum combinationibus (cf. Fichant 1991: 136-8) in which he calculated the number of possible locutions generated by 23 letters. He took into account neither the question of whether the resulting sequences had a sense, nor even that of whether they were capable of being pronounced at all.

The locutions could consist of anything from 2 to 23 letters; he did not allow repetitions. He arrived at a result of more than 70,000 billion billion. To write out all these locutions would require more than a million billion billion letters.

To conceive of the enormity of this figure, he asked the reader to imagine writing all these words in huge notebooks: each of these notebooks had 1,000 pages; each of these pages had 100 lines; each of these lines could accommodate 60 characters.

One would need 257 million billion of these notebooks. Where would you put them all? Guldin then made a careful volumetric study, imagining shelf space and room for circulation in the libraries that might store a consignment of these dimensions.

If you housed the notebooks in large libraries formed by cubes whose sides measured 432 feet, the number of such cubic buildings (hosting 32 million volumes each) would be 8,050,122,350. And where would you put them all? Even exhausting the total available surface space on planet earth, one would still find room for only 7,575,213,799!

In 1636 Father Marin Mersenne, in his Harmonie universelle, asked the same question once again. This time, however, to the dictiones he added “songs,” that is, musical sequences.

With this, the conception of universal language has begun to appear, for Mersenne realizes that the answer would necessarily have to include all the locutions in all possible languages. He marveled that our alphabet was capable of supplying “millions more terms than the earth has grains of sand, yet it is so easy to learn that one hardly needs memory, only a touch of discernment” (letter to Peiresc, c. April 1635; cf. Coumet 1975; Marconi 1992).

In the Harmonie, Mersenne proposed to generate only pronounceable words in French, Greek, Arabic, Chinese and every other language. Even with this limitation one feels the shudder provoked by a sort of Brunian infinity of possible worlds.

The same can be said of the musical sequences that can be generated upon an extension of 3 octaves, comprising 22 notes, without repetitions (shades of future 12-tone compositions!).

Mersenne observed that to write down all these songs would require enough reams of paper to fill in the distance between heaven and earth, even if every sheet contained 720 of these 22-note songs and every ream was so compressed as to be less than an inch thick.

In fact the number of possible songs amounted to 1,124,000,727,777,607,680,000 (Harmonie, 108). By dividing this figure by the 362,880 songs contained in each ream, one would still obtain a 16-digit figure, whilst the number of inches between the center of the earth and the stars is only 28,826,640,000,000 (a 14-digit figure).

Anyone who wished to copy out all these songs, a thousand per day, would have to write for 22,608,896,103 years and 12 days.”

Eco: Bruno: Ars Combinatoria & Infinite Worlds, 3


Giordano Bruno (1548-1600), a mnemonic diagram, which appears towards the end of Cantus circaeus (Incantation of Circe), 1582, which also appears on the cover of Opere mnemotecniche, Vol. 1: De umbris idearum, 1582, Rita Sturlese, et al, ed. 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 her critical edition of De umbris (1991), Sturlese gives an interpretation of the use of the wheels that differs sharply from the “magical” interpretation given by Yates (1972). For Yates, the wheels generated syllables by which one memorizes images to be used for magical purposes.

Sturlese inverts this: for her, it is the images that serve to recall the syllables. Thus, for Sturlese, the purpose of the entire mnemonical apparatus was the memorization of an infinite multitude of words through the use of a fixed, and relatively limited, number of images.

If this is true, then it is easy to see that Bruno’s system can no longer be treated as an art where alphabetic combinations lead to images (as if it were a scenario-generating machine); rather, it is a system that leads from combined images to syllables.

Such a system not only aids memorization but, equally, permits the generation of an almost unlimited number of words–be they long and complex like incrassatus or permagnus, or difficult like many Greek, Hebrew, Chaldean, Persian or Arabic terms (De umbris, 169), or rare like scientific names of grass, trees, minerals, seeds or animal genera (De umbris, 152). The system is thus designed to generate languages–at least at the level of nomenclature.

Which interpretation is correct? Does Bruno concatenate the sequence CROCITUS to evoke the image of Pilumnus advancing rapidly on the back of a donkey with a bandage on his arm and a parrot on his head, or has he assembled these images so as to memorize CROCITUS?

In the “Prima Praxis” (De umbris, 168-72) Bruno tells us that it is not indispensable to work with all five wheels because, in most known languages, it is rare to find words containing syllables with four or five letters.

Furthermore, where such syllables do occur (for instance, in words like trans-actum or stu-prans), it is usually eash to devise some artifice that will obviate the necessity of using the fourth and fifth wheel.

We are not interested in the specific short cuts that Bruno used except to say that they cut out several billion possibilities. It is the very existence of such short cuts that seems significant.

If the syllabic sequences were expressing complex images, there should be no limit for the length of the syllables. On the contrary, if the images were expressing syllables, there would be an interest in limiting the length of the words, following the criteria of economy already present in most natural languages (even though there is no formal limit, since Leibniz will later remark that there exists in Greek a thirty-one-letter word).

Besides, if the basic criterion of every art of memory is to recall the unfamiliar through the more familiar, it seems more reasonable that Bruno considered the “Egyptian” traditional images as more familiar than the words of exotic languages.

In this respect, there are some passages in De umbris that are revealing: “Lycas in convivium cathenatus presentabat tibi AAA. . . . Medusa, cum insigni Plutonis presentabit AMO” (“Lycaon enchained in a banquet presents to you AAA . . . Medusa with the sign of Pluto presents AMO”).

Since all these names are in the nominative case, it is evident that they present the letters to the user of the system and not the other way around. This also follows from a number of passages in the Cantus circaeus where Bruno uses perceivable images to represent mathematical or abstract concepts that might not otherwise be imaginable or memorizable (cf. Vasoli 1958: 284ff).

That Bruno bequeathed all this to the Lullian posterity can be seen from further developments of Lullism.”

Eco: Lullian Kabbalism


Unknown artist, Roma 1493, depicting the city of Rome as it appeared in that year. This woodcut was published in Hartmann Schedel (1440-1514), Schedelsche Weltchronik, Nürnberg, 1493, on folio lvii verso and lviii recto. Known in English as the Nuremberg Chronicle, or Schedel’s World Chronicle, the work commissioned by Sebald Schreyer (1446-1520) and Sebastian Kammermeister (1446-1503) was lushly illustrated with the first depictions of many cities. 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. 

“We have now reached a point where we must collect what seem the various membra disiecta of the traditions we have been examining and see how they combined to produce a Lullian revival.

We can begin with Pico della Mirandola: he cited Lull in his Apologia of 1487. Pico, of course, would have been aware that there existed analogies between the permutational techniques of Lull and the temurah (which he called “revolutio alphabetaria“).

He was acute enough, however, to realize that they were two different things. In the Quaestio Sexta of the Apologia, where Pico proved that no science demonstrates the divinity of Christ better than magic and the kabbala, he distinguished two doctrines which might be termed kabbalist only in a figurative (transumptive) sense: one was the supreme natural magic; the other was the hokmat ha-zeruf of Abulafia that Pico termed an “ars combinandi,” adding that “apud nostros dicitur ars Raymundi licet forte diverso modo procedat” (“it is commonly designated as the art of Raymond, although it proceeds by a different method”).

Despite Pico’s scruples, a confusion between Lull and the kabbala was, by now, inevitable. It is from this time that the pathetic attempts of the Christian kabbalists to give Lull a kabbalistic reading begin.

In the 1598 edition of Lull’s works there appeared, under Lull’s name, a short text entitled De auditu kabbalistico: this was nothing other than Lull’s Ars brevis into which had been inserted a number of kabbalistic references.

It was supposedly first published in Venice in 1518 as an opusculum Raimundicum. Thorndike (1923-58: v, 325) has discovered the text, however, in manuscript form, in the Vatican Library, with a different title and with an attribution to Petrus de Maynardis.

The manuscript is undated, but, according to Thorndike, its calligraphy dates it to the fifteenth century. The most likely supposition is that it is a composition from the end of that century in which the suggestions first made by Pico were taken up and mechanically applied (Scholem et al. 1979: 40-1).

In the following century, the eccentric though sharp-witted Tommaso Garzoni di Bagnacavallo saw through the imposture. In his Piazza universale du tutte le arti (1589: 253), he wrote:

“The science of Raymond, known to very few, might be described with the term, very improper in itself, of Cabbala. About this, there is a notion common to all scholars, indeed, to the whole world, that in the Cabbala can be found teachings concerning everything [ . . . ] and for this reason one finds in print a little booklet ascribed to him [Lull] (though on this matter people beyond the Alps write many lies) bearing the title De Auditu Cabalistico. This is nothing but a brief summary of the Arte Magna as abbreviated, doubtlessly by Lull himself, into the Arte Breve.”

Still, the association persisted. Among various examples, we might cite Pierre Morestel, who published an Artis kabbalisticae, sive sapientiae diviniae academia in 1621, no more than a modest compilation from the De auditu.

Except for the title, and the initial identification of the Ars of Lull with the kabbala, there was nothing kabbalistic in it. Yet Morestel still thought it appropriate to include the preposterous etymology for the word kabbala taken from De auditu: “cum sit nomen compositum ex duabus dictionibus, videlicet abba et ala. Abba enim arabice idem quod pater latine, et ala arabice idem est quod Deus meus” (“as this name is composed of two terms, that is abba and ala. Abba is an Arabic word meaning Latin pater; ala is also Arabic, and means Deus meus“).

For this reason, kabbala means “Jesus Christ.”

The cliché of Lull the kabbalist reappears with only minimum variation throughout the writings of the Christian kabbalists. Gabriel Naudé, in his Apologie pour tous les grands hommes qui ont esté accuséz de magie (1625), energetically rebutted the charge that the poor Catalan mystic engaged in the black arts.

None the less, French (1972: 49) has observed that by the late Renaissance, the letters from B to K, used by Lull, had become associated with Hebrew letters, which for the kabbalists were names of angels or of divine attributes.”

Eco: Kabbalism & Lullism in the Steganographies

“A peculiar mixture of kabbalism and neo-Lullism arose in the search for secret writings–steganographies. The progenitor of this search, which was to engender innumerable contributions between humanism and the baroque, was the prolific Abbot Johannes Trithemius (1462-1516).

Trithemius made no references to Lull in his works, relying instead on kabbalistic tradition, advising his followers, for instance, that before attempting to decipher a passage in secret writing they should invoke the names of angels such as Pamersiel, Padiel, Camuel and Aseltel.

On a first reading, these seem no more than mnemonic aids that can help either in deciphering or in ciphering messages in which, for example, only the initial letters of words, or only the initial letters of even-numbered words (and so on according to different sets of rules), are to be considered.

Thus Trithemius elaborated texts such as “Camuel Busarchia, menaton enatiel, meran sayr abasremon.” Trithemius, however, played his game of kabbala and steganography with a great deal of ambiguity. His Poligraphia seems simply a manual for encipherment, but with his posthumous Steganographia (1606 edition) the matter had become more complex.

Many have observed (cf. Walker 1958: 86-90, or Clulee 1988: 137) that if, in the first two books of this last work, we can interpret Trithemius‘ kabbalist references in purely metaphorical terms, in the third book there are clear descriptions of magic rituals.

Angels, evoked through images modeled in wax, are subjected to requests and invocations, or the adept must write his own name on his forehead with ink mixed with the juice of a rose, etc.

In reality, true steganography would develop as a technique of composing messages in cipher for political or military ends. It is hardly by chance that this was a technique that emerged during the period of conflict between emerging national states and flourished under the absolutist monarchies.

Still, even in this period, a dash of kabbalism gave the technique an increased spice.

It is possible that Trithemius‘ use of concentric circles rotating freely within each other owed nothing to Lull: Trithemius employed this device not, as in Lull, to make discoveries, but simply to generate or (decipher) cryptograms.

Every circle contains the letters of the alphabet; if one rotates the inner wheel so as to make the inner A correspond, let us say, to the outer C, the inner B will be enciphered as D, the inner C as E and so on (see also our ch. 9).

It seems probable that Trithemius was conversant enough with the kabbala to know certain techniques of temurah, by which words or phrases might be rewritten, substituting for the original letters the letters of the alphabet in reverse (Z for A, Y for B, X for C, etc.).

This technique was called the “atbash sequence;” it permitted, for example, the tetragrammaton YHWH to be rewritten as MSPS. Pico cited this example in one of his Conclusiones (cf. Wirzubski 1989: 43).

But although Trithemius did not cite him, Lull was cited by successive steganographers. The Traité des chiffres by Vigenère (1587) not only made specific references to Lullian themes, but also connected them as well to the factorial calculations first mentioned in the Sefer Yezirah.

However, Vigenère simply follows in the footsteps of Trithemius, and, afterwards, of Giambattista Della Porta (with his 1563 edition of De furtivis literarum notis, amplified in subsequent editions): he constructed tables containing 400 pairs generated by 20 letters; these he combined in triples to produce what he was pleased to call a “mer d’infini chiffrements à guise d’un autre Archipel tout parsemé d’isles . . . un embrouillement plus malaisé à s’en depestrer de tous les labrinthes de Crete ou d’Egypte” (pp. 193-4), a sea of infinite cryptograms like a new Archipelago all scattered with isles, an imbroglio harder to escape from than all the labyrinths of Crete and Egypt.

The fact that these tables were accompanied by lists of mysterious alphabets, some invented, some drawn from Middle Eastern scripts, and all presented with an air of secrecy, helped keep alive the occult legend of Lull the kabbalist.

There is another reason why steganography was propelling a Lullism that went far beyond Lull himself. The steganographers had little interest in the content (or the truths) expressed by their combinations.

Steganography was not a technique designed to discover truth: it was a device by which elements of a given expression-substance (letters, numbers or symbols of any type) might be correlated randomly (in increasingly differing ways so as to render their decipherment more arduous) with the elements of another expression-substance.

It was, in short, merely a technique in which one symbol replaced another. This encouraged formalism: steganographers sought ever more complex combinatory stratagems, but all that mattered was engendering new expressions through an increasingly mind-boggling number of purely syntactic operations. The letters were dealt with as unbound variables.

By 1624, in his Cryptometrices et cryptographie libri IX, Gustavus Selenus was designing a wheel of 25 concentric volvelles, each of them presenting 24 pairs of letters. After this, he displays a series of tables that record around 30,000 triples. From here, the combinatory possibilities become astronomical.”

Eco: Postel’s Universalistic Utopia

Guillaume Postel, The Great Key, Eliphas Levi, The Key of the Great Mysteries, 1861

Guillaume Postel (1510-81), The Great Key, in Eliphas Levi (1810-75), La Clef des Grands MystèresThe Key of the Great Mysteries, 1861.

“A special place in the story of the renewal of Hebrew studies belongs to the French utopian thinker and érudit, Guillaume Postel (1510-81). Councillor to the kings of France, close to the major religious, political and scientific personalities of his epoch, Postel returned from a series of diplomatic missions to the Orient, voyages which enabled him to study Arabic and Hebrew as well as to learn of the wisdom of the kabbala, a changed and marked man.

Already renowned as a Greek philologist, around 1539, Postel was appointed to the post of “mathematicorum et peregrinarum linguarum regius interpretes” in that Collège des Trois Langues which eventually became the Collège de France.

In his De originibus seu de Hebraicae linguae et gentis antiquitate (1538), Postel argued that Hebrew came directly from the sons of Noah, and that, from it, Arabic, Chaldean, Hindi and, indirectly, Greek had all descended as well.

In Linguarum duodecem characteribus differentium alphabetum, introductio (1538), by studying twelve different alphabets he proved the common derivation of every language. From here, he went on to advance the project of a return to Hebrew as the instrument for the peaceable fusion of the peoples of differing races.

To support his argument that Hebrew was the proto-language, Postel developed the criterion of divine economy. As there was but one human race, one world and one God, there could be but one language; this was a “sacred language, divinely inspired into the first man” (De Foenicum litteris, 1550).

God had educated Adam by breathing into him the capacity to call things by their appropriate names (De originibus, seu, de varia et potissimum orbit Latino ad hanc diem incognita aut inconsyderata historia, 1553).

Although Postel does not seem to have thought either of an innate faculty for languages or of a universal grammar, as Dante had done, there still appears in many of his writings the notion of an Averroist active intellect as the repository of the forms common to all humanity, in which the roots of our linguistic faculty must be sought (Les très merveilleuses victoires des femmes du nouveau monde together with La doctrine du siècle doré, both from 1553).

Postel’s linguistic studies were connected to his particular vision of a religious utopia: he foresaw the reign of universal peace.

In his De orbis terrae concordia (1544:I) he clearly states that his studies in language would help to lay the foundations upon which a universal concord could be created. He envisioned the creation of a linguistic commonwealth that would serve as living proof to those of other faiths that not only was the message of Christianity true, but equally it verified their own religious beliefs: there are some principles of a natural religion, or sets of innate ideas held by all peoples (De orbis, III).

Here was the spirit that had inspired Lull and Nicholas of Cusa. Yet Postel was convinced that universal peace could only be realized under the protection of the king of France: among the world’s rulers the king of France alone held a legitimate claim to the title of king of the world.

He was the direct descendent of Noah, through Gomer, son of Japheth, founder of the Gallic and Celtic races (cf. particularly Les raisons de la monarchie, c. 1551). Postel (Trésor des propheties de l’univers, 1556) supported this contention with a traditional etymology (see, for example, Jean Lemaire de Belges, Illustration de Gaule et singularitez de Troye, 1512-3, fol. 64r): in Hebrew, the term gallus meant “he who overcame the waves;” thus the Gauls were the people who had survived the waters of the Flood (cf. Stephens 1989:4).

Postel first attempted to convert Francis I to his cause. The king, however, judged him a fanatic, and he lost favor at court. He went to Rome, hoping to win over to his utopian schemes Ignatius of Loyola, whose reformist ideals seemed kindred to his own.

It did not take Ignatius long, however, to realize that Postel’s ambitions were not identical to those of the Jesuits. Accepting Postel’s project might have placed their vow of obedience to the pope at risk.

Besides, Ignatius was a Spaniard, and the idea of turning the king of France into the king of the world would hardly have appealed to him. Although Postel continued long afterwards to look upon the Jesuits as the divine instrument for the creation of universal peace, he himself was forced to leave the company after a mere year and a half.”

Eco: The Concordia Universalis of Nicholas of Cusa

“The seductive potentiality of Lull’s appeal to the principle of universal concord is revealed by the resumption of his project, two centuries later, by Nicholas of Cusa. Nicholas is famous as the figure who revived Plato during the years between the crisis of scholasticism and the beginning of the Renaissance.

Nicholas also propounded the idea of an infinitely open universe, whose centre was everywhere and whose circumference nowhere. As an infinite being, God transcended all limits and overcame every opposition.

As the diameter of a circle increased, its curvature diminished; so at its limit its circumference became a straight line of infinite length.

Likewise, in God all opposites coincide. If the universe had a centre, it would be limited by another universe. But in the universe, God is both centre and circumference. Thus the earth could not be the centre of the universe.

This was the starting point for a vision of the plurality of worlds, of a reality founded on mathematical principles, which can be submitted to continuous investigation, where the world, if not infinite in a strict sense, was at least capable of assuming an infinite number of guises.

The thought of Nicholas is rich in cosmological metaphors (or models) founded upon the image of the circle and the wheel (De docta ignorantia, II, 11), in which the names of the divine attributes (explicitly borrowed from Lull) form a circle where each supports and confirms the others (I, 21).

The influence of Lull is even more explicitly revealed when Nicholas notes that the names by which the Greeks, Latins, Germans, Turks and Saracens designate the divinity are either all in fundamental accord, or derive from the Hebrew tetragrammaton (see the sermon Dies sanctificatus).

The ideas of Lull had spread to the Veneto towards the close of the fourteenth century. Nicholas probably came into contact with them in Padua. Their diffusion was, in part, a reaction against a scholastic Aristotelianism now in crisis; yet the diffusion also reflected the feverish cultural atmosphere generated by close contacts with the East.

Just as Catalonia and Majorca had been frontier territories in contact with the Muslim and Jewish worlds at the time of Lull, so the Venetian Republic had opened itself to the world of Byzantium and of the Arab countries two centuries later. The emerging currents of Venetian humanism were inspired by a new curiosity and respect for other cultures (cf. Lohr 1988).

It was thus appropriate that in this atmosphere there should have reemerged the thought of a figure whose preaching, whose theological speculations, and whose research on universal language were all conceived with the aim of building an intellectual and religious bridge between the European West and the East.

Lull believed that true authority could not be based on a rigid unity, but rather on the tension between various centers. It was the laws of Moses, the revelations of Christ and the preaching of Mohammed that, taken together, might produce a unified result.

Lull’s doctrine acted as a mystical and philosophical stimulus and seemed an imaginative and poetic alternative to the encyclopedia of Aristotelian scholasticism, but it provided a political inspiration as well.

The works of a writer who had dared to put his doctrine into the vernacular proved congenial to humanists who, on the one hand, had begun to celebrate the dignity of their own native tongues, but, on the other hand, wondered how it was possible to establish a rational discussion which broke the boundaries of national traditions, a philosophy which could reanimate the body of encyclopedic scholasticism by injecting the leaven of exotic new doctrines, expressed in languages still entirely unknown.

In his De pace fidei, Nicholas opened a polemical dialogue with the Muslims. He asked himself Lull’s question: how might the truth of Christian revelation be demonstrated to followers of the two other monotheistic religions?

Perhaps, Nicholas mused, it was a mistake to translate the persons of the Trinity as “Father,” “Son” and “Holy Ghost.” Perhaps they should have been given more philosophical names (better understandable by other cultures).

In his ecumenical fervor, Nicholas even went so far as to propose to the Jews and the Muslims that, if they would accept the Gospels, he would see that all Christians received circumcision. It was a proposal, as he confessed at the end, whose practical realization might present certain difficulties. (De pace fidei, XVI, 60).

Nicholas retained from Lull the spirit of universal peace as well as his metaphysical vision. Yet before the thrilling potential of Nicholas’s own vision of an infinity of worlds could be translated into a new and different version of the art of combination, new ideas would have to fertilize the humanist and Renaissance world.

The rediscovery of the art of combination would have to wait for the rediscovery of Hebrew, for Christian kabbalism, for the spread of Hermeticism, and for a new and positive reassessment of magic.”

Eco: The Arbor Scientarium

Ramon Llull, Liber de ascensu et decensu intellectus, 1304, first published 1512. 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 Lullian art was destined to seduce later generations who imagined that they had found in it a mechanism to explore the numberless possible connections between dignities and principles, principles and questions, questions and virtues or vices.

Why not even construct a blasphemous combination stating that goodness implies an evil God, or eternity a different envy? Such a free and uncontrolled working of combinations and permutations would be able to produce any theology whatsoever.

Yet the principles of faith, and the belief in a well-ordered cosmos, demanded that such forms of combinatorial incontinence be kept repressed.

Lull’s logic is a logic of first, rather than second, intentions; that is, it is a logic of our immediate apprehension of things rather than of our conceptions of them. Lull repeats in various places that if metaphysics considers things as they exist outside our minds, and if logic treats them in their mental being, the art can treat them from both points of view.

Consequently, the art could lead to more secure conclusions than logic alone, “and for this reason the artist of this art can learn more in a month than a logician can in a year.” (Ars magna, X, 101).

What this audacious claim reveals, however, is that, contrary to what some later supposed, Lull’s art is not really a formal method.

The art must reflect the natural movement of reality; it is therefore based on a notion of truth that is neither defined in the terms of the art itself, nor derived from it logically. It must be a conception that simply reflects things as they actually are.

Lull was a realist, believing in the existence of universals outside the mind. Not only did he accept the real existence of genera and species, he believed in the objective existence of accidental forms as well.

Thus Lull could manipulate not only genera and species, but also virtues, vices and every other sort of differentia as well; at the same time, however, all those substances and accidents could not be freely combined because their connections were determined by a rigid hierarchy of beings (cf. Rossi 1960: 68).

In his Dissertatio de arte combinatoria of 1666, Leibniz wondered why Lull had limited himself to a restricted number of elements. In many of his works, Lull had, in truth, also proposed systems based on 10, 16, 12 or 20 elements, finally settling on 9. But the real question ought to be not why Lull fixed upon this or that number, but why the number of elements should be fixed at all.

In respect of Lull’s own intentions, however, the question is beside the point; Lull never considered his to be an art where the combination of the elements of expression was free rather than precisely bound in content.

Had it not been so, the art would not have appeared to Lull as a perfect language, capable of illustrating a divine reality which he assumed from the outset as self-evident and revealed.

The art was the instrument to convert the infidels, and Lull had devoted years to the study of the doctrines of the Jews and Arabs. In his Compendium artis demonstrativa (“De fine hujus libri“) Lull was quite explicit: he had borrowed his terms from the Arabs.

Lull was searching for a set of elementary and primary notions that Christians held in common with the infidels. This explains, incidentally, why the number of absolute principles is reduced to nine (the tenth principle, the missing letter A, being excluded from the system, as it represented perfection or divine unity).

One is tempted to see in Lull’s series the ten Sefirot of the kabbala, but Plazteck observes (1953-4: 583) that a similar list of dignities is to be found in the Koran. Yates (1960) identified the thought of John Scot Erigene as a direct source, but Lull might have discovered analogous lists in various other medieval Neo-Platonic texts–the commentaries of pseudo-Dionysius, the Augustinian tradition, or the medieval doctrine of the transcendental properties of being (cf. Eco 1956).

The elements of the art are nine (plus one) because Lull thought that the transcendental entities recognized by every monotheistic theology were ten.

Lull took these elementary principles and inserted them into a system which was already closed and defined, a system, in fact, which was rigidly hierarchical–the system of the Tree of Science.

To put this in other terms, according to the rules of Aristotelian logic, the syllogism “all flowers are vegetables, X is a flower, therefore X is a vegetable” is valid as a piece of formal reasoning independent of the actual nature of X.

For Lull, it mattered very much whether X was a rose or a horse. If X were a horse, the argument must be rejected, since it is not true that a horse is a vegetable. The example is perhaps a bit crude; nevertheless, it captures very well the idea of the great chain of being (cf. Lovejoy 1936) upon which Lull based his Arbor scientiae (1296).”

Eco: The Ars Magna of Raymond Lull

Raymond Lull, Tabula Generalis, pg. 57, Eco, Search for a Perfect Language, 1995

Raymond Lull (1232-1316), Tabula Generalis, figure 4.1, Lull’s Alphabet, from Umberto Eco, The Search for a Perfect Language, Blackwell, Oxford, 1995, pg. 57. 

“A near contemporary of Dante, Ramòn Llull (Latinized as Lullus and Anglicized as Lull–and sometimes as Lully) was a Catalan, born in Majorca, who lived probably between 1232 (or 1235) and 1316.

Majorca during this period was a crossroads, an island where Christian, Jewish and Arab cultures all met; each was to play a role in Lull’s development. Most of his 280 known works were written initially in Arabic or Catalan (cf. Ottaviano 1930).

Lull led a carefree early life which ended when he suffered a mystic crisis. As a result, he entered the order of Tertian friars.

It was among the Franciscans that all of the earlier strands converged in his Ars magna, which Lull conceived as a system for a perfect language with which to convert the infidels. The language was to be a universal; it was to be articulated at the level of expression in a universal mathematics of combination; its level of content was to consist of a network of universal ideas, held by all peoples, which Lull himself would devise.

St. Francis had already sought to convert the sultan of Babylonia, and the dream of establishing universal concordance between differing races was becoming a recurrent theme in Franciscan thought. Another of Lull’s contemporaries, the Franciscan Roger Bacon, foresaw that contact with the infidels (not merely Arabs, but also Tartars) would require study of foreign languages.

The problem for him, however, was not that of inventing a new, perfect language, but of learning the languages that the infidels already spoke in order to convert them, or, failing that, at least to enrich Christian culture with a wisdom that the infidels had wrongfully appropriated (“tamquam ab iniustis possessoribus“).

The aims and methods of Lull and Bacon were different; yet both were inspired by ideals of universality and of a new universal crusade based on peaceful dialogue rather than on arms.

In this utopia the question of language played a crucial role (cf. Alessio 1957). According to legend, Lull was to die martyred at the hands of the Saracens, to whom he had appeared, armed with his art, believing it to be an infallible means of persuasion.

Lull was the first European philosopher to write doctrinal works in the vulgar tongue. Some are even in popular verses, so as to reach readers who knew neither Latin nor Arabic: “per tal che hom puscha mostrar / logicar e philosophar / a cels que win saben lati / ni arabichi” (Compendium, 6-9).

His art was universal not merely in that it was designed to serve all peoples, but also in that it used letters and figures in a way (allegedly) comprehensible even to illiterates of any language.”
