"Philosophie et non-philosophie du poétique" indique une double attitude de la philosophie française contemporaine : pour maîtriser la pensée, elle revient sur soi, mais elle peut aussi ne pas participer à ce mouvement. Le "poétique", objet de l'attitude, implique alors le "poétique" et le "non-poétique", deux usages des expériences fondamentales du langage. La première expérience est la surdétermination du langage qui se rapporte à la pensée de la maîtrise. La deuxième est l'expérience de l'immanence du langage à soi sans retour (...) possible de la pensée. En passant par le poétique, la première attitude vise à la maîtrise de l'immanence. En passant par le non-poétique, la deuxième attitude remet en discussion la maîtrise de l'immanence par la notion d'une naïveté radicale et par la théorie du poétique. Nous parvenons ainsi à la distinction entre la pensée qui met l'immanence en discussion – la philosophie – et la pensée qui part de l'impossibilité de cette mise en discussion – la non-philosophie.

In the last few decades the role played by models and modeling activities has become a central topic in the scientific enterprise. In particular, it has been highlighted both that the development of models constitutes a crucial step for understanding the world and that the developed models operate as mediators between theories and the world. Such perspective is exploited here to cope with the issue as to whether error-based and uncertainty-based modeling of measurement are incompatible, and thus alternative with one (...) another, as sometimes claimed nowadays. The crucial problem is whether assuming this standpoint implies definitely renouncing to maintain a role for truth and the related concepts, particularly accuracy, in measurement. It is argued here that the well known objections against true values in measurement, which would lead to refuse the concept of accuracy as non-operational, or to maintain it as only qualitative, derive from a not clear distinction between three distinct processes: the metrological characterization of measuring systems, their calibration, and finally measurement. Under the hypotheses that (1) the concept of true value is related to the model of a measurement process, (2) the concept of uncertainty is related to the connection between such model and the world, and (3) accuracy is a property of measuring systems (and not of measurement results) and uncertainty is a property of measurement results (and not of measuring systems), not only the compatibility but actually the conjoint need of error-based and uncertainty-based modeling emerges.

In the present paper we propose a system of propositional logic for reasoning about justification, truthmaking, and the connection between justifiers and truthmakers. The logic of justification and truthmaking is developed according to the fundamental ideas introduced by Artemov. Justifiers and truthmakers are treated in a similar way, exploiting the intuition that justifiers provide epistemic grounds for propositions to be considered true, while truthmakers provide ontological grounds for propositions to be true. This system of logic is then applied both for (...) interpreting the notorious definition of knowledge as justified true belief and for advancing a new solution to Gettier counterexamples to this standard definition.

Keenan (1987) observed that trivial determiners built from basic existential determiners (e.g.,either zero or else more than zero) are allowed inthere-insertion contexts, and that trivial determiners built from basic non-existential determiners (e.g.,either all or else not all) are not. This result is unexpected under the analyses ofthere-sentences proposed in Barwise and Cooper (1981), Higginbotham (1987), and Keenan (1987). I argue that the class of NPs barred from the postverbal position ofthere-sentences (strong NPs) is correctly characterized in presuppositional terms, as suggested (...) in de Jong and Verkuyl (1985) and Lumsden (1988). According to this characterization, strong NPs share one of the defining components of definiteness proposed in Heim (1982), namely the Descriptive Content Condition (DCC). How to derive the prohibition against strong NPs inthere-insertion contexts (definiteness effect) from the fact that strong NPs meet the DCC is not obvious, however. I argue that accounting for this prohibition involves regarding the XP-coda in [there be NP XP] as providing the contextual domain for the interpretation of the postverbal NP. (shrink)

We prove that the theory IΔ0, extended by a weak version of the Δ0-Pigeonhole Principle, proves that every integer is the sum of four squares (Lagrange's theorem). Since the required weak version is derivable from the theory IΔ0 + ∀x (xlog(x) exists), our results give a positive answer to a question of Macintyre (1986). In the rest of the paper we consider the number-theoretical consequences of a new combinatorial principle, the ‘Δ0-Equipartition Principle’ (Δ0EQ). In particular we give a new proof, (...) which can be formalized in IΔ0 + Δ0EQ, of the fact that every prime of the form 4n + 1 is the sum of two squares. (shrink)

Nel 1913 Adolf Reinach pubblica I Fondamenti A Priori del Diritto Civile, opera che rappresenta senza dubbio il capolavoro del giovane fenomenologo tedesco. Il saggio si staglia sul denso sfondo di questioni semantiche, ontologiche e psicologico-descrittive dibattute a cavallo tra Otto e Novecento nei circoli fenomenologici di Monaco e Gottinga. Tali questioni, che rappresentano il vero e proprio terreno fertile dell’opera, nei Fondamenti non diventano però tema esplicito dell’indagine. Quest...

The purpose of the present paper is to provide a way of understanding systems of logic of essence by introducing a new semantic framework for them. Three central results are achieved: first, the now standard Fitting semantics for the propositional logic of evidence is adapted in order to provide a new, simplified semantics for the propositional logic of essence; secondly, we show how it is possible to construe the concept of necessary truth explicitly by using the concept of essential truth; (...) finally, Fitting semantics is adapted in order to present a simplified semantics for the quantified logic of essence.

This is the classic study of the history and continuing philosophical values of the law of nature. D'Entrèves discerned three distinct sources that have contributed to the development of natural law: Roman law teachings, Christian beliefs regarding law, and egalitarian and revolutionary theories of the Enlightenment. Now regarded as a classic work, Natural Law has exercised considerable influence over the course of Anglo-American legal theory in the past forty years. The statements of Clarence Thomas during his 1991 Senate confirmation hearings (...) show that the law of nature still holds powerful appeal in defining judicial rules. In the new introduction, Cary J. Nederman points out both the contemporary value and the historical significance of Natural Law. He also provides the biographical as well as intellectual context for d'Entrèves immense accomplishments. This volume is essential reading for students of legal history, political theory, and philosophy. It will also be of interest to historians. "Few texts provide as concise or as cogent an introduction to natural theory as Alexander Passerin d'Entrèves' Natural Law: An Introduction to Legal Philosophy.... Transaction Publishers has performed a genuine service by bringing out a new edition of Natural Law. D'Entrèves' analysis is clear and penetrating, and will guide the student of natural law to further, fruitful study."--Mitchell Muncy, The University Bookman. (shrink)

We develop an intersection theory for definable Cp-manifolds in an o-minimal expansion of a real closed field and we prove the invariance of the intersection numbers under definable Cp-homotopies . In particular we define the intersection number of two definable submanifolds of complementary dimensions, the Brouwer degree and the winding numbers. We illustrate the theory by deriving in the o-minimal context the Brouwer fixed point theorem, the Jordan-Brouwer separation theorem and the invariance of the Lefschetz numbers under definable Cp-homotopies. A. (...) Pillay has shown that any definable group admits an abstract manifold structure. We apply the intersection theory to definable groups after proving an embedding theorem for abstract definably compact Cp-manifolds. In particular using the Lefschetz fixed point theorem we show that the Lefschetz number of the identity map on a definably compact group, which in the classical case coincides with the Euler characteristic, is zero.

It is assumed sometimes that the input of a measurement, and therefore the entity with which a measuring system interacts, is a quantity value, possibly the (true) measurand value, and from this hypothesis the model of ideal measurement as an identity process is formulated. In this paper we show that this position is based on an inappropriate superposition of quantities and quantity values, and therefore should be discarded.

This volume is the second part of a project which hosts an interdisciplinary discussion about the relationship among law and language, legal practice and ordinary conversation, legal philosophy and the linguistics sciences. An international group of authors, from cognitive science, philosophy of language and philosophy of law question about how legal theory and pragmatics can enrich each other. In particular, the first part is devoted to the analysis of how pragmatics can solve problems related to legal theory: What can pragmatics (...) teach about the concept of law and its relationship with moral, and, in particular, about the eternal dispute between legal positivism and legal naturalism? What can pragmatics teach about the concept of law and/or legal disagreements? The second part is focused on legal adjudication: it aims to construct a pragmatic apparatus appropriate to legal trial and/or to test the tenure of the traditional pragmatics tools in the field. The authors face questions such as: Which interesting pragmatic features emerge from legal adjudication? What pragmatic theories are better suited to account for the practice of judgment or its particular aspects? Which pragmatic and socio-linguistic problems are highlighted by this practice? (shrink)

The essay aims to focus on reception and interpretation of Dostoevsky in the thought of Luigi Pareyson and his heirs, who have developed a deep and original theoretical reading of Dostoevsky's work, able to bring out not only its ethical stance, but most of the essential aspects of his thought, and to investigate its current relevance. The reflection of Pareyson – who promoted the introduction of Dostoevsky's thought into the academic circles of Turin, being convinced that philosophy cannot avoid confronting (...) the issues it explores – consists of three main moments: the experience of good and evil, the experience of freedom and the experience of God. Starting from consideration of Dostoevsky's characters as ideas, Pareyson proposes a new and coherent philosophical interpretation of his work, which can undoubtedly be compared to those of Ivanov, Berdjaev, Evdomikov, Šestov. His observations around the Legend of the Grand Inquisitor and the "refutation of Ivan" – which, according to him, constitute the most significant and theoretically prolific moments of Dostoevsky's production – seem unaffected by the flow of time and could still represent a valuable and indispensable contribution to the understanding not only of the great Russian author, but of human nature itself.

L’articolo si propone di ricostruire criticamente il processo di crisi e trasformazione del concetto di impero a ridosso delle rivoluzioni settecentesche. A partire dalla Histoire des deux Indes di Raynal, e dalla critica illuminista ai differenti modelli imperiali, Pandolfi delinea il passaggio dal colonialismo classico – costruito attorno al rapporto tra coloni, selvaggi e schiavi – a una fase contraddistinta invece dallo sfruttamento indiretto della forza lavoro. La trattazione porta alla luce l’ambivalenza illuminista nei confronti della questione dell’impero, dimostrando come (...) l’opera di Raynal intersechi e restituisca al lettore le tensioni fondanti della seconda metà del Settecento. Così, ripercorrendo l’analisi di Diderot, l’autore dimostra come l’avanzamento morale dell’umanità sia il prodotto della costante interazione tra la retorica imperialista del commercio e le rivoluzioni che, in luoghi e momenti diversi, hanno attraversato lo spazio coloniale.

Wilkie 5 397) proved a “theorem of the complement” which implies that in order to establish the o-minimality of an expansion of with C∞ functions it suffices to obtain uniform bounds on the number of connected components of quantifier free definable sets. He deduced that any expansion of with a family of Pfaffian functions is o-minimal. We prove an effective version of Wilkie's theorem of the complement, so in particular given an expansion of the ordered field with finitely many C∞ (...) functions, if there are uniform and computable upper bounds on the number of connected components of quantifier free definable sets, then there are uniform and computable bounds for all definable sets. In such a case the theory of the structure is effectively o-minimal: there is a recursively axiomatized subtheory such that each of its models is o-minimal. This implies the effective o-minimality of any expansion of with Pfaffian functions. We apply our results to the open problem of the decidability of the theory of the real field with the exponential function. We show that the decidability is implied by a positive answer to the following problem ): given a language L expanding the language of ordered rings, if an L-sentence is true in every L-structure expanding the ordered field of real numbers, then it is true in every o-minimal L-structure expanding any real closed field.

In questo lavoro vengono sviluppate alcune considerazioni sulla funzione dell’istruzione nel presente contesto storico–culturale, in particolare riguardo alla matematica. Tra i molti aspetti che rendono l’epoca attuale diversa dalle precedenti ve ne sono due che più di altri invocano la necessità di un cambiamento nelle impostazioni didattiche. Il primo è una crisi che, per durata ed estensione, appare non più come dinamica di aggiustamento all’interno di un modello ma come irreversibile degenerazione del modello stesso. Il secondo riguarda la quantità di (...) informazione a cui l’individuo ha accesso e la facilità e velocità di tale accesso. Cambiamenti così profondi provocano una domanda: i modi e i contenuti della didattica devono rimanere gli stessi o occorre ripensare l’istruzione progettando cambiamenti altrettanto irreversibili quanto lo sono quelli dell’economia e della società? Queste considerazioni ci portano a una riflessione sul rapporto tra educazione e società e, più in generale, tra cultura e società. I prodotti scientifici e culturali sono dei codici cristallizzati come idee platoniche o piuttosto acquistano valenza e significato a partire dal contesto in cui nascono? Questa domanda poi ne richiama altre ancora sul rapporto tra individuo, sistema scolastico e società. In che misura il ruolo della scuola di standardizzare la cultura è compatibile con quello di favorire la creatività e le possibilità espressive dell’individuo? E cosa significa oggi dare all’individuo gli strumenti per sviluppare al meglio le proprie possibilità? L’insegnante dovrebbe osservare, ipotizzare, sperimentare, esplorare opportunità senza pregiudizi culturali. Egli sa che molte idee che sulla carta sembrano vincenti potrebbero rivelarsi inefficaci, ma ciò non deve costituire un alibi. Se infatti si possono nutrire dei dubbi su alcune proposte di innovazione, su una cosa vi è certezza: la didattica tradizionale ha ormai poco senso ed è totalmente inadeguata rispetto alle sfide di questi e dei prossimi anni.

Il saggio intende mostrare come nell’ambito dell’ attività intellettuale di Marsilio Ficino, volta a superare la divaricazione tra sapienza e religione attraverso il recupero della tradizione platonica ed ermetica, la riflessione sull’uomo non si limiti a mettere in evidenza la presenza del divino nell’uomo e la possibilità della mens di attingere la realtà intelligibile, ma si estenda ad altre importanti tematiche. Tramite il costante confronto tra l’uomo e gli animali, Ficino illustra la condizione umana, sottolinea la differenza tra libertà dell’agire (...) e determinismo naturale, si sofferma sulla relazione natura-cultura, caratterizza la religione naturale come prerogativa esclusiva dell’uomo.

Summary This article presents a comparative analysis of the concepts of totalitarian democracy and positive liberty in the work of Jacob Leib Talmon and Isaiah Berlin. Its main purpose is to show that a combined analysis of Talmon and Berlin's biographical relationship and their individual texts demonstrates that Talmon's idea of totalitarian democracy may have had a greater influence on Berlin's notion of positive liberty than Berlin seems to have ever acknowledged. The article first summarises the intellectual and biographical relationships (...) that tied these two authors together in a personal friendship and an intellectual fellowship that lasted for more than three decades. In the second part, the insights drawn from the investigation of the authors' intellectual and biographical relationships are linked to an analysis of their texts, The Origins of Totalitarian Democracy and Two Concepts of Liberty. Finally, in the third part of the article, three crucial aspects of Talmon's definition of totalitarian democracy are considered: the interpretation of the Enlightenment and Rousseau's thought, the view of the French revolution, and the possible impact each of these has on subsequent Marxist and socialist reflection, to see how they are addressed in Berlin's idea of positive liberty.
