The logical status of abstraction principles, and especially Hume’s Principle, has been long debated, but the best currently availeble tool for explicating a notion’s logical character—permutation invariance—has not received a lot of attention in this debate. This paper aims to fill this gap. After characterizing abstraction principles as particular mappings from the subsets of a domain into that domain and exploring some of their properties, the paper introduces several distinct notions of permutation invariance for such principles, assessing the philosophical significance (...) of each.

Decisions in the environmental and in particular the climate domain are burdened with uncertainty. Here, we focus on uncertainties faced by individuals when making decisions about environmental behavior, and we use the statistical sampling framework to develop a classification of different sources of uncertainty they encounter. We then map these sources to different public policy strategies aiming to help individuals cope with uncertainty when making environmental decisions.

The purpose of this note is to present a simplification of the system of arithmetical axioms given in previous work; specifically, it is shown how the induction principle can in fact be obtained from the remaining axioms, without the need of explicit postulation. The argument might be of more general interest, beyond the specifics of the proposed axiomatization, as it highlights the interaction of the notion of Dedekind-finiteness and the induction principle.

In this paper, we explore Fregean metatheory, what Frege called the New Science. The New Science arises in the context of Frege’s debate with Hilbert over independence proofs in geometry and we begin by considering their dispute. We propose that Frege’s critique rests on his view that language is a set of propositions, each immutably equipped with a truth value (as determined by the thought it expresses), so to Frege it was inconceivable that axioms could even be considered to be (...) other than true. Because of his adherence to this view, Frege was precluded from the sort of metatheoretical considerations that were available to Hilbert; but from this, we shall argue, it does not follow that Frege was blocked from metatheory in toto. Indeed, Frege suggests in Die Grundlagen der Geometrie a metatheoretical method for establishing independence proofs in the context of the New Science. Frege had reservations about the method, however, primarily because of the apparent need to stipulate the logical terms, those terms that must be held invariant to obtain such proofs. We argue that Frege’s skepticism on this score is not warranted, by showing that within the New Science a characterization of logical truth and logical constant can be obtained by a suitable adaptation of the permutation argument Frege employs in indicating how to prove independence. This establishes a foundation for Frege’s metatheoretical method of which he himself was unsure, and allows us to obtain a clearer understanding of Frege’s conception of logic, especially in relation to contemporary conceptions.

This paper introduces a generalization of Reiter’s notion of “extension” for default logic. The main difference from the original version mainly lies in the way conflicts among defaults are handled: in particular, this notion of “general extension” allows defaults not explicitly triggered to pre-empt other defaults. A consequence of the adoption of such a notion of extension is that the collection of all the general extensions of a default theory turns out to have a nontrivial algebraic structure. This fact has (...) two major technical fall-outs: first, it turns out that every default theory has a general extension; second, general extensions allow one to define a well-behaved, skeptical relation of defeasible consequence for default theories, satisfying the principles of Reflexivity, Cut, and Cautious Monotonicity formulated by D. Gabbay. (shrink)

La “referencia al origen es un invariante cultural” . Sin embargo, cada país tiene modos particulares de procesar su propia historia. Este trabajo analiza una de las modalidades en que –en Argentina– se narra ese origen, en el contexto de los bicentenarios latinoamericanos.

Esos relatos de no-ficción junto a otros de ficción permiten problematizar la cuestión del género y su (...) relación con “la nación” como matriz cultural. Un modo de imaginar un “nosotros” y de permitir ciertas inclusiones y exclusiones identitarias en el momento del origen y en el presente del Bicentenario. (shrink)

This paper presents a formalization of first-order arithmetic characterizing the natural numbers as abstracta of the equinumerosity relation. The formalization turns on the interaction of a nonstandard cardinality quantifier with an abstraction operator assigning objects to predicates. The project draws its philosophical motivation from a nonreductionist conception of logicism, a deflationary view of abstraction, and an approach to formal arithmetic that emphasizes the cardinal properties of the natural numbers over the structural ones.

Aldo Antonelli offers a novel view on abstraction principles in order to solve a traditional tension between different requirements: that the claims of science be taken at face value, even when involving putative reference to mathematical entities; and that referents of mathematical terms are identified and their possible relations to other objects specified. In his view, abstraction principles provide representatives for equivalence classes of second-order entities that are available provided the first- and second-order domains are in the equilibrium dictated (...) by the abstraction principles, and whose choice is otherwise unconstrained.entities are the referents of abstraction terms: such referents are to an extent indeterminate, but we can still quantify over them, predicate identity or non-identity, etc. Our knowledge of them is limited, but still substantial: we know whatever has to be true no matter how the representatives are chosen, i.e., what is true in all models of the corresponding abstraction principles. This view is backed up by an “austere” conception of universals, according to which these are first-order objects, i.e., ways of collecting first-order objects. Antonelli thus claims that second-order logic does not import any novel ontological commitment beyond ontology of first-order, naturalistically acceptable, objects. Moreover, in the case of arithmetic, even if Hume’s Principle is construed as described above, Frege’s Theorem goes through unaffected, since there is nothing in its proof that depends on an account of the “true nature” of numbers. A viable construal of logicism is then given by the combination of semantic nominalism and a naturalistic conception of abstraction. [Editors note]. (shrink)

In this paper we argue that Revision Rules, introduced by Anil Gupta and Nuel Belnap as a tool for the analysis of the concept of truth, also provide a useful tool for defining computable functions. This also makes good on Gupta's and Belnap's claim that Revision Rules provide a general theory of definition, a claim for which they supply only the example of truth. In particular we show how Revision Rules arise naturally from relaxing and generalizing a classical construction due (...) to Kleene, and indicate how they can be employed to reconstruct the class of the general recursive functions. We also point at how Revision Rules can be employed to access non-minimal fixed points of partially defined computing procedures. (shrink)

This book covers the basic guidelines of Vittorio Benussi’s research during the period at Graz and at Padua. It does so in the light of a thorough study of his Nachlass. The book re-evaluates Benussi’s work as a historical piece, and shows how his work is still relevant today, especially in the areas of cognitive psychology and cognitive science. The volume deals with this original and ingenious - though largely ignored - scholar and discusses his work as a leading experimental (...) psychologist. Benussi’s contributions as discussed in this book were particularly relevant in the fields of visual and tactile perception, time perception, forensic psychology, hypnosis and suggestion, unconscious, and emotions. His classical papers are impressive in their originality, energy, range of approaches, experimental skill, the wealth of findings, and the quality of theoretical discussions. This book demonstrates that Benussi was ahead of his time and that his themes, experiments and research programmes are highly relevant to contemporary cognitive psychology. (shrink)

This study presents a web-based sentence comprehension test aimed at identifying high school students who are at risk for a language delay. By assessing linguistic skills on a sample of high school students with Italian as an L2 and their monolingual peers, attending a vocational school, we were able to identify a subgroup of L2 students with consistent difficulties in sentence comprehension, though their reading skills were within the average range. The same subgroup revealed to experience a lack of support (...) within the school context, suggesting that poor L2 skills might be a critical variable to consider in order to identify students at risk for school exclusion. Regarding the test, accuracy to the on-line sentence comprehension task was significantly predicted by reading abilities and vocabulary skills, thus indicating that this test might represent a rapid but efficient way to assess linguistic abilities at school. We recommend that establishing a valid and practical procedure for the evaluation of linguistic skills in bilingual students who struggle with their L2 is the first step towards promoting social inclusion in the multilingual classroom, in order to increase their ability to actively participate in school and social activities.

In this paper we apply the idea of Revision Rules, originally developed within the framework of the theory of truth and later extended to a general mode of definition, to the analysis of the arithmetical hierarchy. This is also intended as an example of how ideas and tools from philosophical logic can provide a different perspective on mathematically more “respectable” entities. Revision Rules were first introduced by A. Gupta and N. Belnap as tools in the theory of truth, and they (...) have been further developed to provide the foundations for a general theory of (possibly circular) definitions. Revision Rules are non-monotonic inductive operators that are iterated into the transfinite beginning with some given “bootstrapper” or “initial guess.” Since their iteration need not give rise to an increasing sequence, Revision Rules require a particular kind of operation of “passage to the limit,” which is a variation on the idea of the inferior limit of a sequence. We then define a sequence of sets of strictly increasing arithmetical complexity, and provide a representation of these sets by means of an operator G(x, φ) whose “revision” is carried out over ω2 beginning with any total function satisfying certain relatively simple conditions. Even this relatively simple constraint is later lifted, in a theorem whose proof is due to Anil Gupta. (shrink)

This is a title on the foundations of defeasible logic, which explores the formal properties of everyday reasoning patterns whereby people jump to conclusions, reserving the right to retract them in the light of further information. Although technical in nature the book contains sections that outline basic issues by means of intuitive and simple examples. This book is primarily targeted at philosophers interested in the foundations of defeasible logic, logicians, and specialists in artificial intelligence and theoretical computer science.

Doing phenomenological research entails a complex process that is only minimally published in scientific journals. What is often missing reflects how being in research calls into question the researchers themselves. Anyone who has conducted qualitative empirical research knows that personal engagement does not come at no cost; there are multiple pedagogical and professional practice gains. This article’s aim is to share the phenomenology behind phenomenology: the reflection and personal experience of doing/being in phenomenological research and the personal narrative of what (...) this experience has meant concerning the authors' own context: health care and nursing. Taking advantage of a conducted research exploring the lived experience of family caregivers of hematological patients assisted at home, we propose considerations about the perceived epistemic and cognitive gains, the formative and personal/professional sequels of having been reflective participants of phenomenologically oriented research.

One of the most important developments over the last twenty years both in logic and in Artificial Intelligence is the emergence of so-called non-monotonic logics. These logics were initially developed by McCarthy [10], McDermott & Doyle [13], and Reiter [17]. Part of the original motivation was to provide a formal framework within which to model cognitive phenomena such as defeasible inference and defeasible knowledge representation, i.e., to provide a formal account of the fact that reasoners can reach conclusions tentatively, reserving (...) the right to retract them in the light of further information.

Aggregation methods allow one to replace a large scale dynamical system (micro-system) by a reduced dynamical system (macro-system) governing a small number of global variables. This aggregation of variables can be performed when two time scales exist, a fast time scale and a slow time scale. Perturbation theory allows to obtain an approximated aggregated dynamical system which describes the behaviour of a few number of slow time varying variables which are constants of motion of the fast part of the micro-system. (...) Aggregation methods are applied to the case of the devastation of the great barrier reef by the starfishes. We recall the Antonelli/Kazarinoff model which implies a stable limit cycle for the corals and starfish populations. This prey-predator model describes the interactions between two species of corals and the starfish. Then, we generalize the Antonelli/Kazarinoff model to the case of two spatial patches with a fast part describing the starfish migration on the patches and the human manipulation of the communities by divers and, a slow part describing the growth and the interactions between the populations. We obtain an aggregated model governing the total coral densities on the patches and the total starfish population. This model can exhibit stable limit cycle oscillations and a Hopf bifurcation. The critical value of the bifurcation parameter is expressed in terms of the proportions of coral species and starfish on the two patches. This implies for example that rather than random killing of starfish by the Australian military, it may be better to send teams of divers to outbreaking reefs when they first occur who will then manipulate the community structure to increase protection.

We present an axiomatic approach for a class of finite, extensive form games of perfect information that makes use of notions like “rationality at a node” and “knowledge at a node.” We distinguish between the game theorist's and the players' own “theory of the game.” The latter is a theory that is sufficient for each player to infer a certain sequence of moves, whereas the former is intended as a justification of such a sequence of moves. While in general the (...) game theorist's theory of the game is not and need not be axiomatized, the players' theory must be an axiomatic one, since we model players as analogous to automatic theorem provers that play the game by inferring (or computing) a sequence of moves. We provide the players with an axiomatic theory sufficient to infer a solution for the game (in our case, the backwards induction equilibrium), and prove its consistency. We then inquire what happens when the theory of the game is augmented with information that a move outside the inferred solution has occurred. We show that a theory that is sufficient for the players to infer a solution and still remains consistent in the face of deviations must be modular. By this we mean that players have distributed knowledge of it. Finally, we show that whenever the theory of the game is group-knowledge (or common knowledge) among the players (i.e., it is the same at each node), a deviation from the solution gives rise to inconsistencies and therefore forces a revision of the theory at later nodes. On the contrary, whenever a theory of the game is modular, a deviation from equilibrium play does not induce a revision of the theory. (shrink)

The paper argues against the growing tendency to interpret Brentano’s conception of inner consciousness in self-representational terms. This trend has received support from the tendency to see Brentano as a forerunner of contemporary same-order theories of consciousness and from the view that Brentano models intransitive consciousness on transitive consciousness, such that a mental state is conscious insofar as it is aware of itself as an object. However, this reading fails to take into account the Brentanian concept of object, which is (...) ultimately derived from ancient and medieval philosophy, as well as the secondary, elusive character that Brentano attributes to inner perception. According to Brentano, we have an aspectual but transparent consciousness of transcendent objects, whereas our awareness of our own mental acts is always complete but incidental, and ultimately opaque. Reversing the relationship between intentionality and consciousness faces difficulties at the textual interpretative level, but also raises theoretical problems, for it risks treating Brentano’s theory of mind as a form of subjectivism and idealism.

In line with earlier works, this article argues for a “continuist” interpretation of Brentano’s conception of intentionality. It maintains that Brentano’s conception of intentionality rests on a complex set of notions, which are reduced to a minimal core or applied more fully depending on the complexity of the mental phenomenon under consideration and perspective from which it is analyzed. The article positions this conceptual structure in relation to theories of objects developed within the framework of late- and Neo-Scholastic philosophy where, (...) since the psychic act can relate to its object in different ways, the different types and roles of objects must be distinguished. This theory of objects enables Brentano to reinterpret Aristoteles’s idea of the intentionality of mental phenomena in light of the commentaries and interpretations of Thomas Aquinas while also giving space to other medieval texts.

In this paper we show that the Gupta-Belnap systems S# and S* are П12. Since Kremer has independently established that they are П12-hard, this completely settles the problem of their complexity. The above-mentioned upper bound is established through a reduction to countable revision sequences that is inspired by, and makes use of a construction of McGee.

This article, inspired by Rudolf Haller’s thesis of an independent, specific, and unitary Austrian tradition of scientific philosophy, develops the idea of a specific Austrian tradition of psychological research, as distinguished in its development from that in Germany. This tradition was shaped by two phenomenological trends, which were merged into unity in Prague by Carl Stumpf and Brentano’s students of the second generation. One trend traces back to Goethe and was continued in Prague by the physiologists Jan E. Purkinje and (...) Ewald Hering, culminating in the work of Ernst Mach. The other trend was initiated by Franz Brentano and spread through his school. Stumpf was the key integrator of these two traditions, which he then partially passed on to his Berlin students and founders of Gestalt psychology. Finally, Karl Bühler’s “reimport” of the Brentanian psychological legacy into the Vienna of the First Republic is briefly illustrated. (shrink)

Mathematics and philosophy have historically enjoyed a mutually beneficial and productive relationship, as a brief review of the work of mathematician–philosophers such as Descartes, Leibniz, Bolzano, Dedekind, Frege, Brouwer, Hilbert, Gödel, and Weyl easily confirms. In the last century, it was especially mathematical logic and research in the foundations of mathematics which, to a significant extent, have been driven by philosophical motivations and carried out by technically minded philosophers. Mathematical logic continues to play an important role in contemporary philosophy, and (...) mathematically trained philosophers continue to contribute to the literature in logic. For instance, modal logics were first investigated by philosophers and now have important applications in computer science and mathematical linguistics. (shrink)

Logic is an ancient discipline that, ever since its inception some 2500 years ago, has been concerned with the analysis of patterns of valid reasoning. Aristotle first developed the theory of the syllogism (a valid argument form involving predicates and quantifiers), and later the Stoics singled out patterns of propositional argumentation (involving sentential connectives). The study of logic flourished in ancient times and during the middle ages, when logic was regarded, together with grammar and rhetoric (the other two disciplines of (...) the trivium), as the foundation of humanistic education.

The term "non-monotonic logic" covers a family of formal frameworks devised to capture and represent defeasible inference , i.e., that kind of inference of everyday life in which reasoners draw conclusions tentatively, reserving the right to retract them in the light of further information. Such inferences are called "non-monotonic" because the set of conclusions warranted on the basis of a given knowledge base does not increase (in fact, it can shrink) with the size of the knowledge base itself. This is (...) in contrast to classical (first-order) logic, whose inferences, being deductively valid, can never be "undone" by new information. (shrink)

While second-order quantifiers have long been known to admit nonstandard, or interpretations, first-order quantifiers (when properly viewed as predicates of predicates) also allow a kind of interpretation that does not presuppose the full power-set of that interpretationgeneral” interpretations for (unary) first-order quantifiers in a general setting, emphasizing the effects of imposing various further constraints that the interpretation is to satisfy.

A propositional system of modal logic is second-order if it contains quantifiers ∀p and ∃p, which, in the standard interpretation, are construed as ranging over sets of possible worlds (propositions). Most second-order systems of modal logic are highly intractable; for instance, when augmented with propositional quantifiers, K, B, T, K4 and S4 all become effectively equivalent to full second-order logic. An exception is S5, which, being interpretable in monadic second-order logic, is decidable.

Quentin Meillassoux es un filósofo francés que ha cobrado notoriedad a partir de la publicación de Après la finitude. Essai sur la nécessité de la contingence en 2006. Su obra se inscribe en el Realismo Especulativo, movimiento de reciente expansión en el campo filosófico contemporáneo que promueve una ontología realista. Además de reivindicar una filosofía materialista, Meillassoux defiende la inmanencia ya en su tesis doctoral L’inexistence divine y, especialmente, en el artículo “L’immanence: d’outre-monde”, donde afirma que una verdadera filosofía de (...) la inmanencia no puede fundamentarse en un pensamiento de la finitud sino en una ética de la inmortalidad.

La thèse de l’« inexistence intentionnelle » formulée par Brentano a été traditionnellement interprétée comme une théorie de la « relation intentionnelle », autrement dit de la relation entre l’acte mental et son « objet immanent » ou « intentionnel », c’est-à-dire interne à la conscience. Se fondant sur la lecture du fameux passage sur l’intentionnalité de la Psychologie du point de vue empirique , le présent article démontre que l’interprétation ontologique de la théorie de l’intentionnalité du premier Brentano est (...) insoutenable, toute dominante qu’elle est. Pour ce faire, nous partirons des sources de la pensée de Brentano, en particulier de la théorie de la perception et des relatifs d’Aristote, pour rejeter la conception de l’objet immanent ou intentionnel comme entité immanente à la conscience et mettre en évidence la continuité qui existe entre la première conception de Brentano de l’intentionnalité et la seconde, consécutive à ce qu’on définit comme le tournant réiste de sa pensée.Brentano’s thesis of “intentional inexistence” has been traditionally interpreted as a theory of “intentional relationships”, i.e., of the relation between a mental act and its “immanent” or “intentional object”, within consciousness. Starting from the famous passage on intentionality in Psychology from an Empirical Standpoint , the present paper shows that the dominant ontological interpretation of Brentano’s former theory of intentionality is untenable. Proceeding from the sources of Brentano’s thought, in particular from Aristotle’s theory of perception and of relatives, the conception of the immanent or intentional object as an immanent entity to consciousness is rejected. Instead, the continuity between Brentano’s former conception of intentionality and the subsequent one, following the so-called reistic turning-point in his thought, is highlighted. (shrink)

Frege's logicist program requires that arithmetic be reduced to logic. Such a program has recently been revamped by the "neologicist" approach of Hale and Wright. Less attention has been given to Frege's extensionalist program, according to which arithmetic is to be reconstructed in terms of a theory of extensions of concepts. This paper deals just with such a theory. We present a system of second-order logic augmented with a predicate representing the fact that an object x is the extension of (...) a concept C, together with extra-logical axioms governing such a predicate, and show that arithmetic can be obtained in such a framework. As a philosophical payoff, we investigate the status of the so-called Hume's Principle and its connections to the root of the contradiction in Frege's system. (shrink)

The paper focuses on a specific point addressed in the previous article of L. Cesalli and H. Taieb The road to “ideelle Verähnlichung”, namely, the correctness of Marty’s interpretation of the early (pre-reistic) Brentanian conception of intentionality. Moving from the distinction between immanent (or intentional) object and intentional correlate, as developed by Brentano in his lectures on Descriptive Psychology, and referring to Aristotelian theory of relativa, which Brentano always remained faithful to, I show that Marty interpreted Brentano’s early conception of (...) intentionality in an immanentistic sense. Thus, the foundations for the so-called ‘ontological’ or ‘discontinuist view’ of Brentano’s intentionality thesis were put down, and through the exegesis of his pupils and Brentano’s Enkelschüler Kastil and Kraus it was then passed on, from generation to generation, until the present day.

What kind of feeling is shame? Why are we ashamed and what are the consequences that this emotion has on the subject? Is it a private or a "social" emotion? How many types of shame exist?

Is it possible to be immune to shame? Would "Not being ashamed" count as a virtue or is it a (...) morally reprehensible attitude? Sensibilia. Colloquium on Perception and Experience investigated the different ways in which shame can be described and staged, presupposed and understood.

The result was a heated debate on (ancient and contemporary) inconvenient, thorny and "shameful" issues. (shrink)

El concepto de "inmanencia" ha adquirido una creciente relevancia en el campo filosófico contemporáneo.

En segundo lugar, examinamos las críticas que Jullien le dirige a Deleuze respecto a la relación entre la filosofía y la sabiduría. En tercer lugar, confrontamos sus perspectivas divergentes sobre la inmanencia en tanto "plano" (Deleuze) y como "fondo" (Jullien). Finalmente, ponemos de manifiesto la dificultad presente en ambos autores para pensar la idea de inmanencia.

First, we shall compare the usage of the expression "absolutization of immanence" coined by the sinologist in order to put in perspective the idea of transcendence in Chinese thought. This expression was then applied by Deleuze within the frame of the belief in this world. Second, we shall examine Jullien's critique of Deleuze concerning the relationship between Philosophy and Wisdom. Third, we shall confront the divergent perspectives on immanence: as "plane" (Deleuze) and as "buttom" (Jullien). Finally, we shall show the difficulty to ponder the idea of immanence in both authors. (shrink)

This paper investigates the “general” semantics for first-order logic introduced to Antonelli, 637–58, 2013): a sound and complete axiom system is given, and the satisfiability problem for the general semantics is reduced to the satisfiability of formulas in the Guarded Fragment of Andréka et al. :217–274, 1998), thereby showing the former decidable. A truth-tree method is presented in the Appendix.

In Voyous, Jacques Derrida develops his argument starting from the presupposition that democracy as such is the entity whose integrity and immunity are at stake and, therefore, under investigation. This gesture reflects the setting in which ten years before, in Foi et savoir, he had cast his reasoning about the logic of immunity. There, it was one of the sources of religion, the immunity of the sacred, that operated according to this logic. The hyphen between these two essays, beside Derrida’s (...) own crossed references, is the genealogical reasoning on the meaning and essence of the concept of democracy: contrary to what Derrida claims, it will be maintained that Athenian democracy had a clear immune matrix, whose constant exercise is clearly defined, in spite of himself, by Vernant, and it will be shown how modern democracy has been forced to change policy. Modern democracy is an entity characterized by an immune deficiency. In order to save Derrida’s intuition from both the collapse of different vantage points and from a quite bizarre reticence in taking into account of the immune value of rituals, our starting point will be René Girard’s œuvre and his reading of the role of immune logic in sacred systems and, more generally, in modernity. The threshold between the auto-immune reaction, immune deficiency and auto-immune disease, between the sacrifice who delimits and constitutes the self and the holocauste du peuple en détail, is the space where, constantly exposed to the risk of auto-denial, democracy lives.
