Aristotle's theory of truth, which has been the most influential account of the concept of truth from Antiquity onwards, spans several areas of philosophy: philosophy of language, logic, ontology and epistemology. In this 2004 book, Paolo Crivelli discusses all the main aspects of Aristotle's views on truth and falsehood. He analyses in detail the main relevant passages, addresses some well-known problems of Aristotelian semantics, and assesses Aristotle's theory from the point of view of modern analytic philosophy. In the process (...) he discusses most of the literature on Aristotle's semantic theory to have appeared in the last two centuries. His book vindicates and clarifies the often repeated claim that Aristotle's is a correspondence theory of truth. It will be of interest to a wide range of readers working in both ancient philosophy and modern philosophy of language. (shrink)

Some philosophers argue that false speech and false belief are impossible. In the Sophist, Plato addresses this 'falsehood paradox', which purports to prove that one can neither say nor believe falsehoods. In this book Paolo Crivelli closely examines the whole dialogue and shows how Plato's brilliant solution to the paradox is radically different from those put forward by modern philosophers. He surveys and critically discusses the vast range of literature which has developed around the Sophist over the past fifty (...) years, and provides original solutions to several problems that are so far unsolved. His book will be important for all who are interested in the Sophist and in ancient ontology and philosophy of language more generally. (shrink)

Pierre de Fermat is known as the inventor of modern number theory. He invented–improved many methods useful in this discipline. Fermat often claimed to have proved his most difficult theorems thanks to a method of his own invention: the infinite descent. He wrote of numerous applications of this procedure. Unfortunately, he left only one almost complete demonstration and an outline of another demonstration. The outline concerns the theorem that every prime number of the form 4n + 1 is the sum (...) of two squares. In this paper, we analyse a recent proof of this theorem. It is interesting because: it follows all the elements of which Fermat wrote in his outline; it represents a good introduction to all logical nuances and mathematical variants concerning this method of which Fermat spoke. The assertions by Fermat will also be framed inside their historical context. Therefore, the aims of this paper are related to the history of mathematics and to the logic of proof-methods. (shrink)

We review several of de Finetti’s fundamental contributions where these have played and continue to play an important role in the development of imprecise probability research. Also, we discuss de Finetti’s few, but mostly critical remarks about the prospects for a theory of imprecise probabilities, given the limited development of imprecise probability theory as that was known to him.

The concept of« multitude » opposes for a long time to that of the « people ». The people is a homogeneous unity, whereas the multitude is a network of peculiarities. The individuals who compose the multitude are not nevertheless atoms of one given but the result of a process of individuation. Of what consists this individuation which produces the individual from universal conditions ? One can tempt an answer by using Gilbert Simondon’s reflections and Russian psychologist L. Vygotskij. With (...) the aid of these authors one will end maybe in a more relevant comprehension of the Marxian concept of« social individual ». (shrink)

This paper explores how Indic and Indic-derived linguistic analyses of the Buddha’s epithet _bhagavat_ influenced the epithet’s interpretations and translations in the Sanskrit, Pali, Chinese, and Tibetan traditions. The paper consists of three parts. The first part examines and classifies the evidence into four types of analyses that ultimately reflect analytical models afforded by the Indic linguistic disciplines of grammar (_vyākaraṇa_) and etymology (_nirvacana_). The second part explores how these linguistic analyses coordinate with pronouncements emphasizing the epithet’s extraordinary status as (...) opposed to ordinary language terms. The third part examines how these analyses fostered the adoption of certain translations strategies in China and Tibet, focusing on the second of the ‘Five Guidelines for Non-Translating’ (_wǔzhǒng bùfān_ 五種不翻) attributed to Xuanzang (600/602–664) and on pertinent statements recorded in the early-ninth-century Tibetan _Sgra sbyor bam po gñis pa_/_Madhyavyutpatti_. Using _bhagavat_ as an example, this paper aims to demonstrate the important yet little-studied role that Indic and Indic-derived linguistic analyses had in South Asian Buddhism as well as in the Indianized Buddhist cultures of China and Tibet.

This paper aims to recover the ideas about semantics that are contained in Yāska’s _Nirukta_ (c. 6–3 century BCE), the seminal work of the Indian tradition of _nirvacana_ or etymology. It argues that, within the framework of his etymological project, Yāska developed consistent and sophisticated ideas relating to semantics—what I call his theory of meaning. It shows that this theory assumes the form of explicit and implicit reflections pertaining to the relation between three categories: denoting names (_nāman_/_nāmadheya_), denoted objects (_sattva_/_artha_), (...) and name-giving action expressed by verbal roots (_ākhyāta_). A typology of Yāska’s etymologies for what they reveal about semantics will be proposed and investigated. In doing so, attention will be paid to how Yāska’s ideas resemble and anticipate ideas concerning the difference between polysemy and homonymity, metaphoric transfer, and synecdoche. It is hoped that attending to Yāska’s thus-far largely overlooked ideas will help us better appreciate the _Nirukta_’s role in the history of early Indian engagements with semantics. (shrink)

The paper aims to show how the tragic and dramatic elements of Thus Spoke Zarathustra become essential components of the transcendental empiricism in Difference and Repetition, by actualising a virtuality that was inherent in the Nietzchean book but not made explicit by its author. If the meaning of the eternal return is hidden in the four books of Thus Spoke Zarathustra, and if the Deleuzian reading does not aim to interpret and express the interiority of a text, but to machine (...) it, then what Difference and Repetition seeks is something other than the Nietzschean intention. And it is precisely on the basis of this hidden otherness - something that Nietzsche had not (yet) expressed - that Deleuze machines Zarathustra with other texts and other authors. The paper will analyse this experimentation as the concretisation, within Deleuzian philosophy, of the repetition of power that makes Deleuze's Nietzschean May 68. (shrink)

The article analyzes the relationship between absolute knowing and the process of recognition in self-consciousness. The theme is discussed in relation to Hegel's thesis of the scientific character of philosophical knowledge. The article shows how the dialectical relationship between judging consciousness and the consciousness that acts is essential to understand the status of absolute knowing. To support this thesis, the article examines Hegel's discussion on the forms of manifestation of spirit within the chapter “Spirit” and the Hegelian analysis of the (...) relationship between revealed religion and absolute knowing. Selfconsciousness embodies the concept of spirit because it is constituted by the movement of infinity and is therefore a self-differentiating whole. The structure of self-consciousness characterizes the specificity of the Phenomenology of Spirit: the convergence of a form of knowledge and a form of human subjectivity. Another central theme is action, in which the «horizontal» recognition of the selfconsciousnesses gives rise to the «vertical recognition» of spirit.The action itself is the bearer of the unity of essence and Dasein, universality and particularity, substantiality and singular subjectivity.

More than any other philosopher, Duns Scotus and Simondon both gave extensive consideration to the relation between what is primarily common and what is primarily singular. Pointing to certain resonances between their ideas can help us to develop a theoretical model to decipher the mode of being of the contemporary multitude. This article deals with: 1. The critique that Duns Scotus and Simondon address to everyone who believes that the matter form pair can account for the process of individuation; 2. (...) The gap separating the notion of the « universal » from that of the « common », and therefore, the need to precisely define the ontological and logical status of the « common » without any surreptitious use of categories linked to the « universal 1); 3. The paradoxical relation involving both addition and subtraction - between the individuated individual and « common nature »; and 4. The question of angels , a source of enduring fame in school textbooks for Duns Scotus, re-examined here in the light of Simondon ’s concepts of « transindividuality » and of « collective individuation ».

Can we build endogenous expectations about the locus of occurrence of a target without being able to describe them? Participants performed cue–target detection tasks with different proportions of valid and invalid trials, without being informed of these proportions, and demonstrated typical endogenous effects. About half were subsequently able to correctly describe the cue–target relationships . However, even non-verbalizer participants showed endogenous orienting with peripheral cues , not depending solely on practice . Explicit instructions did not bring about dramatic advantages in (...) performance .With central symbolic cues, only verbalizers showed reliable endogenous effects . We concluded that endogenous orienting with peripheral cues can occur independently of participants developing explicit hypotheses about the cue–target relationships. (shrink)

Chapter Θ10 of Aristotle's Metaphysics is traditionally taken to be about the truth of intuitions, namely episodes of an immediate and sub-propositional grasp of entities. This exegesis however saddles Aristotle with a broken-backed theory of truth because in other passages of his works he claims that truth and falsehood apply only to items of a propositional nature and denies that sub-propositional items can be true or false. An alternative exegesis is preferable which takes Θ10 to be about the truth of (...) existential statements and judgements concerning simple items. (shrink)

In this paper, I propose the idea that the French mathematician Michel Chasles developed a foundational programme for geometry in the period 1827–1837. The basic concept behind the programme was to show that projective geometry is the foundation of the whole of geometry. In particular, the metric properties can be reduced to specific graphic properties. In the attempt to prove the validity of his conception, Chasles made fundamental contributions to the theory of polarity and also understood that a satisfactory development (...) of projective geometry has to overcome the specificity of that theory itself. In this perspective, he developed his ideas on duality and homography, showing their dependence on the concept that he was going to pose at the basis of geometry: the anharmonic ratio, today called cross-ratio. The conceptual itinerary that starts from Chasles’ studies on polarity and ends with his results based on the cross-ratio represents the itinerary of his foundational programme. I will follow this complex and interesting line of thought, place it in the context of what was then called descriptive geometry, and outline a connection with the later great results of Von Staudt, Cayley, and Klein.

La struttura a livelli modella il tutto e le sue parti con grande generalità. Lo dimostrano le argomentazioni teoriche (4.3), (4.4) e (4.5), e lo comprova la casistica che è stata aggiunta. Una tale struttura non presenta affatto i problemi a), b) e c) che sono tipici della struttura ad albero. Essa corregge inoltre deviazioni concettuali che sono diffuse nel settore informatico. L’immediatezza deviazioni concettuali che sono diffuse nel settore informatico. L’immediatezza visiva, infine, ne facilita la diffusione sul piano professionale (...) e tecnico.Per concludere, ritengo che la struttura a livelli possa fornire un contributo anche alle ricerche di ontologia e in particolare possa favorire i tentativi di unificazione condotti sia sul piano teorico, sia su quello applicativo [Uschold 1996]. Le difficoltà ed i limiti che la teoria degli insiemi oppone ad un formalismo generale (ad esempio quando riduce la casistica della relazione concetto di livello possiede una valenza estremamente ampia e ciò lo predispone per gli auspicati sviluppi ontologici.

In this study some typical aspects of human behavior are reconsidered in a new evolutionary perspective. Firstly, a theoretical paradigm is introduced, according to which animals show a natural propensity to maintain behavior far beyond the time when the triggering motivation has been removed;, these drifting conducts are defined as Vestigial Drifting Drives or. Such a paradigm is then applied to those human attitudes that once conferred an adaptive advantage on our species but have now become dysfunctional within the framework (...) of the current ecological crisis. In this context, human beings are considered the repository of VDDs that may play out as evolutionary threats. This thesis is supported by many examples and references that, hopefully, could stimulate scientific debate and further research in evolutionary anthropology, psychology, and related disciplines.

The two theories of pancreatic enzyme secretion, those of exocytosis and transmembrane flow, are described. Data thought to support the theory of transmembrane flow of single molecules from pancreatic acinar cells are first reviewed, and the conditions which could allow these data to be explained by the theory of exocytosis of enzyme quanta, i.e. secretory granules, are then discussed.The evidence suggesting short‐term modulation of the composition of pancreatic juice is also considered, and its possible explanations at the organ and cellular (...) level are discussed, in the light of suggested theories on enzyme secretion pathways.

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)
