From the Tree to the Labyrinth
secundum ponentes speciem, species est aliquid praevium omni actui intelligendi objectum, igitur non potest poni propter repraesentationem objecti” (Quaest. In II Sent. Reportatio, 12–13). See also Tabarroni (1984).
  • “Sicut per istam ‘Homo est animal’ denotatur quod Sortes vere est animal. Per istam autem ‘Homo est nomen’ denotatur quod haec vox ‘homo’ est nomen … Similiter per istam “Album est animal,” denotatur quod illa res, quae est alba, sit animal, ita quod haec sit vera: ‘Hoc est animal,’ demonstrandum illam rem, quae est alba et propter hoc pro illa re subjectum supponit.… Nam per istam: ‘Sortes est albus’ denotatur, quod Sortes est illa res, quae habet albedinem, et ideo praedicatum supponit pro ista re, quae habet albedinem.… Et ideo si in ista ‘Hic est angelus,’ subjectum et praedicatum supponunt pro eodem, propositio est vera. Et ideo non denotatur, quod hic habeat angelitatem … sed denotatur, quod hic sit vere angelus.… Similiter etiam per tales propositiones: ‘Sortes est homo,’ ‘Sortes est animal’… denotatur quod Sortes vere est homo et vere est animal.… Denotatur quod est aliqua res, pro qua stat vel supponit hoc praedicatum ‘homo’ et hoc praedicatum ‘animal’ ” (Summa, II, 2). There is at least one example, taken from the Elementarium logicae and cited by Maierù, of denotare in the active voice, in which Ockham distinguishes between the two meanings of appellare. The first meaning is Anselm’s, while, apropos of the second, Ockham writes: “aliter accipitur appellare pro termine exigere vel denotare seipsum debere suam propriam formam.” It would seem that here denotare stands for “govern” (or “require”) or postulate a coreference within the framework of the linguistic context.
  • For a similar use of denotari, see Ockham’s Quaestiones in libros Physicorum III, partial edition by Corvino (1955).
  • Maierù (1972) cites Peter of Mantua: “Verba significantia actum mentis ut ‘scio,’ ‘cognosco,’ ‘intelligo,’ etc. denotant cognitionem rerum significatarum a terminis sequentibus ipsa verba per conceptum.” Right after this sentence, Peter gives an example: “Unde ista propositio ‘tu cognoscis Socratem’ significat quod tu cognoscis Socratem per hunc conceptum ‘Socratem’ in recto vel oblique” (Logica, 19vb–20ra). It is evident that denotare and significare mean more or less the same thing, and that both terms are used to speak of propositional aptitudes—an intensional theme if ever there was one.
  • On Llull, Pico, and Llullism
  • We have only to leaf through a few studies on Christian Kabbalism (for instance, Secret 1964; French 1972; Evans 1973) to meet up with the cliché of Ramon Llull the Kabbalist, served up with minimal variations. Llull as magus and alchemist appears in the context of magic in the Prague of Rudolf II, as well as in the library of John Dee, who “was deeply immersed in Llullism and apparently accepted the traditional attitude toward the Llullist-cabalist synthesis” (French 1972: 113). Llull is present in the works of professed Kabbalists (such as Burgonovus, Paulus Scalichius, and the superficial and credulous Belot)1 as well as in those of the enemies of Kabbalism, like Martino Del Rio,2 to the point that, when Gabriel Naudé came to write his Apologie pour tous les grands hommes qui ont été accusés de magie (Paris, 1625) he felt obliged to defend the poor Catalan mystic energetically against any suspicion of necromancy. To add to the confusion, “in a later Renaissance transformation, the letters B through K used in the Llullian Ars became associated with the Hebrew letters that the cabalists contemplated and that supposedly signified angel names and the attributes of God. These Hebrew letters, which were thought to have a summoning power over the angels, were the same ones used by practical cabalists like John Dee” (French 1972: 49).

    Numerology, magic geometry, astrology, and Llullism are inextricably confused, in part because of the series of pseudo-Llullian alchemistic works that invaded the sixteenth-century scene. Furthermore, the names of the Kabbalah could also be carved on seals, and a whole magical and alchemical tradition made seals with a circular structure popular (Llull practiced his art on a circular wheel). And, for his part Athanasius Kircher, in his 1665 Arithmologia, also illustrated a number of magic seals in the form of numerical tables.3

    However, what influence the Kabbalistic tradition had on Llull is not something we need to discuss in the present context. Llull was born in Majorca—a crossroads on the margins of Europe where encounters took place among Christian, Arabic, and Hebrew cultures, and it is certainly not impossible that someone living where three great monotheistic religions met could have been subject to the influence, visual at least, of Kabbalistic speculation. Llull’s Ars combines letters on three concentric wheels and, from the very beginnings of the Kabbalistic tradition, in the Sefer Yetzirah (“Book of Creation,” written at an uncertain date between the second and sixth centuries), the combining of the letters is associated with their inscription on a wheel. What is certain, however, is that nothing is further from Kabbalistic practices than Llull’s Ars, at least as formulated by its founder.

    10.1. What Exactly is Llull’s Ars?

    If we are to understand the internal mechanics of the Ars, we must first review a few principles of Llull’s system of mathematical combinations.
    We have permutation when, given n different elements, every possible change in their order has been realized. The typical case is the anagram.4 We have disposition when n elements are arranged t by t, but in such a way that the order also has differential value (AB and BA, for instance, represent two different dispositions).5 We have combination when, if we have to arrange n elements t by t, inversions of order are not relevant (AB and BA, for instance, represent the same combination).6

    The calculus of the permutations, dispositions, and combinations may be used to solve a number of technical problems, but it could also be used for the purposes of discovery—to delineate, in other words, possible future “scenarios.” In semiotic terms, what we have is a system of expression (made up of symbols and syntactic rules) such that, by associating the symbols with a content, various “states of things” (or of ideas) can be imagined. In order for the combinatory system to be most effective, however, it must be assumed that there are no restrictions on thinking all possible universes. Once we begin to designate certain universes as not possible, either because they are improbable in the light of the evidence of our past experience or because they do not correspond to what we consider to be the laws of reason, then external criteria come into play that induce us, not merely to discriminate among the results of the system of combinations, but also to introduce restrictive rules into the system itself. In the case of Llull, what we have is a proposal for a universal and limitless system of combinations, which as such will fascinate later thinkers, but which at its very inception is severely limited, for reasons both theological and logical.

    Llull’s Ars involves an alphabet of nine letters, from B to K (no distinction is made between I and J), and four combinatory figures. In a Tabula Generalis, Llull establishes a list of six sets of nine entities each (the six are: Absolute Principles or Divine Dignities, Relative Principles, Questions, Subjects, Virtues, Vices). Each entity may be assigned to one of the nine letters (our Figure 10.1).

    Taking Aristotle’s list of categories as a model, the nine Divine Dignities or attributes of God’s being (Bonitas, Magnitudo, Aeternitas or Duratio, Potestas, Sapientia, Voluntas, Virtus, Veritas, and Gloria) are subjects of predication while the other five columns contain predicates.

    Figure 10.1

    The Ars includes four figures or illustrations, which in the various manuscripts are highlighted in different colors.7
    PRIMA FIGURA. Llull’s first figure represents a case of disposition. The nine Absolute Principles are assigned to the letters. Llull explores all the possible combinations among these principles so as to produce propositions such as Bonitas est magna (“Goodness is great”), Duratio est gloriosa (“Duration is glorious”), and so on. The principles appear in nominal form when they are the subject and in adjectival form when they are the predicate, so that the sides of the polygon inscribed in the circle are to be read in two directions (we may read Bonitas est magna, as well as Magnitudo est bona). The possible dispositions of nine elements two by two, when inversions of order are also allowed, permit Llull to formulate seventy-two propositions (see Figure 10.2).

    Figure 10.2

    The figure permits regular syllogisms “ut ad faciendam conclusionem possit medium invenire” (“if the middle term be suitable for reaching a conclusion”) (Ars brevis II).8 To demonstrate that Goodness can be great, it is argued that “omne id quod magnificetur a magnitudine est magnum—sed Bonitas est id quod magnificetur a magnitudine—ergo Bonitas est Magna” (“everything made great by greatness is great—but Goodness is what is made great by greatness—therefore Goodness is great”).

    SECUNDA FIGURA. Llull’s circle (unlike the one in his first figure) does not involve any system of combinations. It is simply a visual-mnemonic device that allows us to remember the connections (already foreordained) among various types of relationships and various types of entities (see Figure 10.3).

    Figure 10.3

    For example, both difference and concordance, as well as contrariety, can be considered with reference to (i) two sensitive entities, such as stone and plant; (ii) one sensitive and one intellectual, such as body and soul; and (iii) two intellectual entities, such as soul and angel.

    TERTIA FIGURA. This figure evidently represents a case of combination, considering that in it all possible pairings of the letters are considered, excluding inversions of order (the table includes BC, for example, but not CB), and the doublets generated are thirty-six, inserted into what Llull dubs thirty-six chambers. But the chambers are virtually seventy-two, because
