The mnemonic arts and the idea of a universal language that would capture the essence of all things were originally associated with cryptology, mysticism, and other occult practices. And it is commonly held that these enigmatic efforts were abandoned with the development of formal logic in the seventeenth century and the beginning of the modern era. In his distinguished book, Logic and the Art of Memory Italian philosopher and historian Paolo Rossi argues that this view is belied by (...) an examination of the history of the idea of a universal language. Based on comprehensive analyses of original texts, Rossi traces the development of this idea from late medieval thinkers such as Ramon Lull through Bruno, Bacon, Descartes, and finally Leibniz in the seventeenth century. The search for a symbolic mode of communication that would be intelligible to everyone was not a mere vestige of magical thinking and occult sciences, but a fundamental component of Renaissance and Enlightenment thought. Seen from this perspective, modern science and combinatorial logic represent not a break from the past but rather its full maturity. Available for the first time in English, this book (originally titled Clavis Universalis ) remains one of the most important contributions to the history of ideas ever written. In addition to his eagerly anticipated translation, Steven Clucas offers a substantial introduction that places this book in the context of other recent works on this fascinating subject. A rich history and valuable sourcebook, Logic and the Art of Memory documents an essential chapter in the development of human reason. (shrink)

Si tratta di una raccolta di saggi scritti tra il '65 e il '69 e pubblicati una prima volta nel 1971. Rivisti e parzialmente aggiornati vengono riproposti con la vecchia introduzione nella quale l'autore polemizza con le critiche della ragione scientifica che caratterizzarono alcuni aspetti della cultura del '68. Il primo saggio è dedicato al declino della astrologia all'inizio dell'età moderna; sottolineando il divario tra la concezione magica che caratterizza la visione astrologica del mondo e le posizione di quella che (...) sarebbe diventata la scienza, Paolo Rossi rivaluta gli scritti contro l'astrologia di Pico della Mirandola. Dopo un breve scritto su Leonardo, l'autore analizza i rapporti tra pensiero baconiano e cristianesimo. Segue un saggio che riesamina alcuni problemi di interpretazione delle lettere di Galileo a Piero Dini e a Cristina di Lorena. Nei capitoli successivi vengono affrontate varie questioni quali, il passaggio dalla concezione aristotelica a quella moderna, il peso di alcune ipotesi astronomiche e in particolare la crisi dell'antropocentrismo. Gli ultimi due capitoli dedicati a dispute di linguistica e di geologia sono particolarmente interessanti; infatti queste due discipline occupano una posizione anomala nella cultura del seicento. Se a quel tempo esistevano matematici, astronomi, medici, non si può certo parlare di linguisti o geologi propriamente detti, questo fatto rende particolarmente difficile e interessante ricostruire lo sviluppo di concetti appartenenti a branche della scienza che non erano ancora consce della loro autonomia.

L’articolo si pone il problema del perché Vico avesse pensato alla sua impresa come ad una scienza e si fosse occupato di confrontarla con la scienza della natura. Si passano in rassegna l’uso di concetti come degnità, assiomi, postulati, tenendo fermo che Vico non fu né un cartesiano, né un galileiano, e come non si lasci racchiudere nelle gabbie dell’apriorismo e del platonismo: egli ha solo fatto sue alcune idee o tesi presenti entro quelle tradizioni. Vico si guarda bene dall’effettuare (...) una scelta precisa e definitiva tra quelle realtà alle quali attribuiamo oggi il nome di razionalismo e empirismo. Si richiama contemporaneamente e negli stessi testi sia alla tradizione del geometrismo cartesiano sia a quella di Bacone e delpensiero dei baconiani del tardo Seicento, facendone un uso alquanto libero. L’articolo contiene inoltre osservazioni su Vico lettore di Cogitata et visa e di De dignitate et augmentis scientarum di Bacone. (shrink)

Taking hints from the Italian writer and comedian Paolo Villaggio’s works having the unlucky-to-the-utmost accountant Fantozzi as their hero, the essay tackles the issue of the role, and the possible foundations, of the law in the theoretical scenario of a perfectly deterministic world, where everything is determined by pre-set nexuses of cause-and-effect. Fantozzi is condemned by such an inescapable law of causation (Fate) to meet constant failure, in a social context structured along stiff hierarchies which are completely independent from (...) individual merits, where law enforcement always sides with the lucky ones. Within such a context, the law cannot be grounded on rational foundations-thinking, since the only possible rational conclusion is that the law is completely useless. At the same time, the law cannot be considered an outcome of power, since any power different from that of Fate is mere illusion. The essay wonders whether, in such a theoretical setting, there is the possibility of finding an alternative foundation for the law on non-objectifying thinking, starting from imagination and the idea of justice. Is it possible to imagine reliable rules based on imagination? (shrink)

In a recent note in this review (Leibniz e gli Zenonisti, n. 3, 2001, pp. 15-22) Paolo Rossi stresses the importance of a philosophical sect that he claims has been unjustly ignored in accounts of the history of modern philosophy, the Jesuit philosophers of Louvain and Spain of the late sixteenth and early seventeenth century known as the Zenonists. The occasion for his complaint is Massimo Mugnai’s admirable new introduction to Leibniz’s thought (Introduzione alla filosofia di Leibniz, Torino, (...) Einaudi, 2001), which in all other respects than its failure to mention the Zenonists, Rossi compliments and commends: justly, for in my opinion it is the best introduction to Leibniz yet written.

This translation of a classic and original work of intellectual history is beautifully done. Rossi’s book Clavis Universalis was first published in Italian in 1960, but Clucas translates the second, revised edition of 1983. The book is about Renaissance and 17th-century encyclopedism, hieroglyphics and cryptography, the techniques of artificial memory, the history of rhetoric, changes in views about logic and method in the scientific revolution, and new ideas about how language and images might reflect or capture reality. Frances Yates’s (...) brilliant The Art of Memory, published in 1966, has so far had much more influence in the English-speaking world. Despite warm citations and many points of contact with Yates’s work, Rossi is less interested in uncovering hidden occult traditions, and more focussed on the way major 17th-century thinkers’ work must be understood against the rich background of schemes for universal grammar and local memory. He shows that scholars working on Bacon, Descartes, and Leibniz miss key references to this intellectual heritage. Half of the book [152] introduces relevant mnemonic, rhetorical, linguistic, medical, and occult writings. Rossi includes illuminating discussions not only of Ramon Lull, Petrus Ramus, Cornelius Agrippa, Giordano Bruno, and all, but also of fascinating minor writers like Guglielmo Gratorolo who systematized advice on medical aids to memory in the mid-16th century, and the wonderful Johannes Spangerbergius, who classified various forms of amnesia in 1570. He then argues that polemic against the arts of memory in both Bacon and Descartes coexisted with intense interest on their part in the supplementing of weak powers of natural memory by various artificial aids and objects outside the boundaries of skull and skin. Rossi tells the strange stories of the great 17th-century encyclopedists and universal language schemers—Alsted, Comenius, Wilkins, Dalgarno—making important connections between Wilkins’s scheme and worries about methods for botanical classification in the early Royal Society. The final chapter is a tour de force on ‘the sources of Leibniz’s universal character’, placing him (as Clucas neatly puts it) ‘at the “end” of a Renaissance intellectual tradition rather than reading him “forwards” as an innovative precursor of modern formal logic’. Historians of science, linguistics, and philosophy have built on many aspects of Rossi’s work since 1983, and Clucas contributes an outstanding introduction which summarizes key strands of recent scholarship.

This book experiments with Nietzsche and Adorno who are contemporary proponents of early German Romanticism. By reconstructing the philosophies of language of these thinkers and their critique of metaphysics and identity thinking, this book develops a notion of philosophical praxis that is grounded in the ethical dimension of thinking.

Numerosity perception is a key ability for human and non-human species, probably mediated by dedicated brain mechanisms. Electrophysiological studies revealed the existence of both early and mid-latency components of the Electrophysiological (EEG) signal sensitive to numerosity changes. However, it is still unknown whether these components respond to physical or perceived variation in numerical attributes. We here tackled this point by recording electrophysiological signal while participants performed a numerosity adaptation task, a robust psychophysical method yielding changes in perceived numerosity judgments despite (...) physical numerosity invariance. Behavioral measures confirmed that the test stimulus was consistently underestimated when presented after a high numerous adaptor while perceived as veridical when presented after a neutral adaptor. Congruently, EEG results revealed a potential at around 200 ms (P2p) which was reduced when the test stimulus was presented after the high numerous adaptor. This result was much prominent over the left posterior cluster of electrodes and correlated significantly with the amount of adaptation. No earlier modulations were retrievable when changes in numerosity were illusory while both early and mid-latency modulations occurred for physical changes. Taken together, our results reveal that mid-latency P2p mainly reflects perceived changes in numerical attributes, while earlier components are likely to be bounded to the physical characteristics of the stimuli. These results suggest that short-term plastic mechanisms induced by numerosity adaptation may involve a relatively late processing stage of the visual hierarchy likely engaging cortical areas beyond the primary visual cortex. Furthermore, these results also indicate mid-latency electrophysiological correlates as a signature of the internal representation of numerical information. (shrink)

It is embarrassing, to say the least, to admit in limine the impossibility of defining the key concepts of this paper, for I do not know either what tradition is or what topoi are. And what is even worse, I have no theoretical conclusions to present. But, after all, why define tradition? We all know what tradition is since it is one of the staples of our academic fare. Even the word itself is in great part an academic one. As (...) a matter of fact, in classical Latin, what we mean by tradition was expressed by words like memoria or institutum or mos vetus, whereas traditio meant surrender or the handing over of a city or of an enemy, although the meaning of instruction, training, teaching is also attested. It was the latter meaning that prevailed in the humanistic period, though with the technical sense of transmission of a text; and in this special meaning the word traditio still survives in the discipline of textual criticism. Of course, the transmission of the text was understood not only in the material sense but also as a means of conveying ancient wisdom, as a witness to its institutions and mores. So the revival of ancient learning implied a reconstruction of a tradition which was thought to have been broken during the Middle Ages. Thus, the studia humanitatis were defined as study of the past, a very well circumscribed past. Even today when we talk about humanistic studies we understand in great part the study of the institutions, mentality, literary movements of the past. Paolo A. Cherci, associate professor in the department of Romance languages and literatures at the University of Chicago, is the editor of Tommaso Garzoni's Works and the author of the forthcoming works, Capitoli di Critica Cervantina, Effemeridi Romaunze, and a collection of short stories, Erostratismo.

Reading or hearing about Theodor Adorno's ideas always results in quibbles. He strikes many as a naïve philosopher because of his reversal of concept and object; some see him as an anarchist because of his relentless critique of rationality; while to others he simply does not make sense, and especially a critique of society based on negative dialectics simply does not make sense to many! These points, however, are precisely some of the key elements of his thought; without a deeper (...) apprehension of these main themes, it would be impossible to arrive at a level-headed appraisal of his philosophy.

In the present paper we discuss a recent suggestion of Schroeder-Heister concerning the possibility of defining an intensional notion of harmony using isomorphism in second-order propositional logic. The latter is not an absolute notion, but its definition is relative to the choice of criteria for identity of proofs. In the paper, it is argued that in order to attain a satisfactory account of harmony, one has to consider a notion of identity stronger than the usual one (based on β- and (...) η-conversions) that the authors have investigated in recent work.
