We present a revenge argument for non-reflexive theories of semantic notions – theories which restrict the rule of assumption, or initial sequents of the form φ ⊩ φ. Our strategy follows the general template articulated in Murzi and Rossi [21]: we proceed via the definition of a notion of paradoxicality for non-reflexive theories which in turn breeds paradoxes that standard non-reflexive theories are unable to block.

In this article we offer a detailed assessment of current approaches to the origins of language, with a special foots on their historical and theoretical underpinnings. It is a widely accepted view within evolutionary linguistics that an account of the emergence of human language necessarily involves paying special attention to its communicative function and its relation to other animal communication systems. Ever since Darwin, some variant of this view has constituted the mainstream version in evolutionary linguistics; however, it is our (...) contention in this article that this approach is seriously flawed, and that “animal communication” does not constitute a natural kind on which a sound theoretical model can be built. As a consequence, we argue that this communicative perspective is better abandoned in favor of a structural/formal approach based on the notion of homology, and that some interesting and unexpected similarities may be found by applying this venerable comparative method founded in the 19th century by Richard Owen.

Our purpose is to present some connections between modal incompleteness andmodal logics related to the Gödel-Löb logic GL. One of our goals is to prove that for all m, n, k, l ∈ ℕ the logic K + equation image□i □jp ↔ p) → equation image□ip is incomplete and does not have the fixed point property. As a consequence we shall obtain that the Boolos logic KH does not have the fixed point property.

We are living in the era of street art. Since Nick Riggle’s pivotal work on the definition of street art, several philosophers have addressed issues in the philosophy of street art. The goal of this paper is to summarize the literature. I consider the following matters, which have been at the core of philosophical discussions on street art: demarcation, value, illegality, and the ethical foundation of intellectual property (IP) protection. In answering the question ‘What is street art?,’ philosophers have generally (...) resisted skeptical approaches by developing a wide range of real and essentialist definitions of street art (Section 2). When considering street art’s value, I distinguish between aesthetic and non-aesthetic centered accounts. If the former focus on the aesthetic side of our experience of street art, the latter generally place emphasis on its activist nature and political significance (Section 3). In discussing the relationship between street art and illegality, I canvas different takes on the issue. If for some scholars illegality is either a necessary or sufficient condition for street art, philosophers tend to agree that it is neither, while not denying its relevance at the level of identity and authenticity (Section 4). Finally, I consider matters of IP protection of street art. On the one hand, copyright optimists defend the view that current IP legislations may very well have a positive impact on the promotion and preservation of street art. Pessimists, on the other hand, argue that an extension of copyright privileges to works of street art is likely to jeopardize the counter-cultural and rebellious nature of this urban art kind (Section 5).

Several different versions of the theory of numerosities have been introduced in the literature. Here, we unify these approaches in a consistent frame through the notion of set of labels, relating numerosities with the Kiesler field of Euclidean numbers. This approach allows us to easily introduce, by means of numerosities, ordinals and their natural operations, as well as the Lebesgue measure as a counting measure on the reals.

As Price (2009) famously mused, if a philosopher were to be magically transported, perhaps through means of time travel, from the 1950s to the modern day, they would indeed be shocked by the resurgence of metaphysics in the analytic tradition. Most of all, perhaps, they would be shocked by the popularity of power metaphysics. What a strange item to have in a philosopher’s curriculum, they might think: after all, didn’t David Hume claim that “[t]here are no ideas which can occur (...) in metaphysics more obscure and uncertain than those of power, force, energy, or necessary connection”? Indeed, much has changed since then. At the pain of using overly vague terminology, we can call “power metaphysics” the subdiscipline of metaphysics interested in the development and evaluation of a family of positions which we will refer to under the umbrella term of “dispositionalism”. According to dispositionalists, the world we inhabit is also populated by genuine and irreducible powers, dispositions, and capacities of objects. (shrink)

El presente artículo es un reconocimiento y un homenaje a L'Höpital, de cuya muerte se ha cumplido recientemente el tercer centenario. En él se estudia la correspondencia L'Höpital-Leibniz para analizar el recientemente creado por Leibiz cálculo diferencial e integral y su ontología subyacente, así como la publicación del primer manual sobre la materia escrito por L'Höpital.

Ecological developmental biology considers the phenotype as actively produced through an environmentally informed process of individual development, rather than predetermined by the genotype. Accordingly, the genotype is viewed as one among many interactants that contribute formative elements; it is understood to do so no differently from the way other organism-internal and environmental resources do. Although the EcoDevo approach is evidently particularly apt to inform approaches to human development, which mostly takes shape in rich cultural environments, it is remarkable that, at (...) least within some highly influential circles of the linguistic sciences, the study of many distinctive human cognitive traits including language remains strongly anchored to a preformationist stance. This article brings an EcoDevo approach to the biologically focused study of language to argue that an aspect of language design commonly assumed to be “blueprinted,” namely, the lexicon-syntax interface, may instead be explained as a plastic effect of ongoing developmental processes in the mind of the child, in which designated aspects of the environment fulfill a key constructive role.

Bas Van Fraassen is a nifty philosopher of science. He received his PhD in Pittsburgh in 1966, under the guidance of Adolf Grünbaum, he taught at Yale University, the university of Toronto, the University of Southern California, he has been McCosh Professor of Philosophy in Princeton, and eventually joined the department of philosophy at San Francisco State University, where he has the title of Distinguished Professor of Philosophy. He first gained attention with his book An Introduction to the Philosophy of (...) Time and Space where he tried to develop a formal theory of space and time based on the notion of causality. The book had an enormous legacy, with experts of the likes of John Earman and David Malament joining the debate. However, he achieved V.I.P. status with his classic The Scientific Image, where he defends a combination of empiricism and antirealism towards unobservable entities based on a re-definition of what the scientific enterprise is. His last achievement is the tome Scientific Representation: Paradoxes of Perspectives, where he combines his scientific empiricism with the view that theories are best thought as models or structures, rather than sets of sentences. In this interview, we talk about his philosophical influences and the birth of The Scientific Image during a journey through North-Africa, Turkey and Eastern Europe, we talk about saving the phenomena and suspending judgement over the existence of unobservable entities, living in world full of mysteries and leaving unanswerable questions unanswered, rationality and irrationality, living in a simulation, the historical interplay between theorizing and experimenting, the meaning of particle detectors for an empiricist, the unity of science and physicalism, the condemnation of Galilei by the Church, and the distinction between Appearance and Reality….

This book aims to develop the tradition of philosophical hermeneutics, the theoretical account of interpretive (as opposed to explanatory) understanding--the account of meanings and contexts rather than causes and predictions--usually restricted to the domain of literary and textual analysis, in new directions by exploiting its potential as an instrument of critique. It refutes commonly held claims that hermeneutic analyses are necessarily relativistic, Eurocentric, or critically impotent and demonstrates how hermeneutic procedures can inform analyses of urgent current and cross-cultural issues such (...) as the biology of race, female genital excision, and the so-called "culture of poverty" thesis. Lorenzo Simpson demonstrates that a robust methodology of philosophical hermeneutics is well positioned to intervene in critical political and social issues in global ethics and justice in concert with critical theory's emancipatory aims.

Un'indagine dello stato dei saperi artistici e scientifici nell'etŕ moderna deve necessariamente partire dall'epistemologia del primo romanticismo tedesco. Il sistema filosofico di Kant, infatti, analizza l'ambito di applicazione del pensiero umano, rilevando che l'arte, in quanto oggetto che sfugge all'indagine razionale della natura, non fornisce alcun tipo di conoscenza. Partendo da tale premessa, e dal ruolo che quindi Kant assegna preliminarmente all'arte, relegandola nell'ambito dell'estetica che č intesa come branca filosofica autonoma distinta dall'indagine razionale della scienza, Fichte, Schelling e i (...) primi romantici tedeschi propongono di riconsiderare l'arte come forma di conoscenza piů alta, in quanto non solo prodotto, ma produzione del sapere stesso per il tramite del medesimo processo conoscitivo su cui si fonda la scienza. Ciononostante, proprio a partire dal romanticismo letteratura, arte e scienza vengono definitivamente separate andando a costituire le basi del nostro attuale paradigma conoscitivo. (shrink)

A genealogical account of state sovereignty explores the ways in which the concept has emerged, evolved, and is in decline today. Sovereignty has a theological foundation, and is deeply bound up with the idea of God, in particular a voluntarist God, presented as being capable of intervening directly in the world. Religious conflicts in the sixteenth and seventeenth centuries forced the separation between religion and politics, and opened the space for the emergence of a national state endowed with sovereignty which (...) has dominated the world until now. Today’s rise of international and transnational obligations challenges the conventional understanding of state sovereignty, which cannot account for the normative density of the global order and the corresponding decline of state-based political authority. In order to explain that, I contrast two competing understandings of state sovereignty: a static one and a dynamic one. The static understanding regards sovereignty as absolute within the state territory. The dynamic understanding regards sovereignty as evolutionary: according to this account, the state is just one possible form that sovereignty can take. I conclude by suggesting that the dynamic understanding of state sovereignty is better suited to explaining the decline of state sovereignty. (shrink)

The book deals with one of the most important issues of philosophy of law and constitutional thought: how to understand clashes of fundamental rights, such as the conflict between free speech and privacy, and develops a framework for adjudication.

The technological advances of contemporary society have outpaced our moral understanding of the problems that they create. How will we deal with profound ecological changes, human cloning, hybrid people, and eroding cyberprivacy, just to name a few issues? In this book, Lorenzo Magnani argues that existing moral constructs often cannot be applied to new technology. He proposes an entirely different ethical approach, one that blends epistemology with cognitive science. The resulting moral strategy promises renewed dignity for overlooked populations, both (...) of today and of the future. (shrink)

This article aims to justify the positive role in the empirical investigation of nature that Kant attributes to the idea of God in the Critique of Pure Reason. In particular, I propose to read the Transcendental Ideal section and the Appendix to the Transcendental Dialectic together to see whether they can reciprocally illuminate each other. I argue that it is only by looking at the transcendental deduction of the ideas of reason and the resulting analogical conception of God that a (...) fully legitimate positive use of the idea of God can be vindicated.

Discussions about dispositional and categorical properties have become commonplace in metaphysics. Unfortunately, dispositionality and categoricity are disputed notions: usual characterizations are piecemeal and not widely applicable, thus threatening to make agreements and disagreements on the matter merely verbal—and also making it arduous to map a logical space of positions about dispositional and categorical properties in which all parties can comfortably fit. This paper offers a prescription for this important difficulty, or at least an inkling thereof. This will be achieved by (...) comparing pairs of positions and exploring their background metaphysics to discover where alleged agreements and disagreements concerning dispositionality and categoricity really lie; more specifically, the Pure Powers view and the Powerful Qualities view will be under scrutiny. Over this background, the prescription functions by isolating a successful identity-based characterization of categoricity, while abandoning the correspondent identity-based characterization of dispositionality. On the contrary, according to this prescription a property is dispositional if and only if it is solely in virtue of possessing that property that its bearer is assigned a certain dispositional profile. A crucial consequence of this prescription is that, while supporters of the Pure Powers view often characterize their position as an essentialist one, the dispositionality of properties needn’t always be a matter of essence.

As humanity becomes increasingly interconnected through globalization, the question of whether community is possible within culturally diverse societies has returned as a principal concern for contemporary thought. Lorenzo Simpson charges that the current discussion is stuck at an impasse-between postmodernism's fragmented notions of cultural difference and humanism's homogeneous versions of community. Simpson proposes an alternative-one that bridges cultural differences without erasing them. He argues that we must establish common aesthetic and ethical standards incorporating sensitivity to difference if we are (...) to achieve cross-cultural understanding. (shrink)

This handbook offers the first comprehensive reference guide to the interdisciplinary field of model-based reasoning. It highlights the role of models as mediators between theory and experimentation, and as educational devices, as well as their relevance in testing hypotheses and explanatory functions. The Springer Handbook merges philosophical, cognitive and epistemological perspectives on models with the more practical needs related to the application of this tool across various disciplines and practices. The result is a unique, reliable source of information that guides (...) readers toward an understanding of different aspects of model-based science, such as the theoretical and cognitive nature of models, as well as their practical and logical aspects. The inferential role of models in hypothetical reasoning, abduction and creativity once they are constructed, adopted, and manipulated for different scientific and technological purposes is also discussed. Written by a group of internationally renowned experts in philosophy, the history of science, general epistemology, mathematics, cognitive and computer science, physics and life sciences, as well as engineering, architecture, and economics, this Handbook uses numerous diagrams, schemes and other visual representations to promote a better understanding of the concepts. This also makes it highly accessible to an audience of scholars and students with different scientific backgrounds. All in all, the Springer Handbook of Model-Based Science represents the definitive application-oriented reference guide to the interdisciplinary field of model-based reasoning. (shrink)

Functional reductionism characterises inter-theoretic reduction as the recovery of the upper-level behaviour described by the reduced theory in terms of the lower-level reducing theory. For instance, finding a statistical mechanical realiser that plays the functional role of thermodynamic entropy allows for establishing a reductive link between thermodynamics and statistical mechanics. This view constitutes a unique approach to reduction that enjoys a number of positive features, but has received limited attention in the philosophy of science. -/- This paper aims to clarify (...) the meaning of functional reductionism in science, with a focus on physics, to define both its place with respect to other approaches to reduction and its connection to ontology. To do so, we develop and explore two alternative frameworks for functional reduction, called Syntactic Functional Reductionism and Semantic Functional Reductionism. They represent two different possible stances on the view that expand and improve the basic functional reductionist approach along different lines, and make clear how the approach works in practice. The former elaborates on David Lewis’ account, is connected with the syntactic view of theories, is committed to a logical characterisation of functional roles, and is embedded within Nagelian reductionism. The latter adopts a semantic view of theories, spells out functional roles mainly in terms of mathematical roles within the models of theories, and is expressed in terms of the related structuralist approach to reduction. The development of these frameworks has the final goal of advancing functional reductionism, to make it a fully-fledged alternative account for reduction in science. (shrink)

The aim of this paper is to propose a novel reading of the critical legitimacy of the regulative use of reason in the Transcendental Dialectic of Kant's Critique of Pure Reason. After introducing some key terminology of the Dialectic, I analyse the shortcomings of two influential accounts of the regulative use of reason and identify their common problem in their commitment to the descriptivity of the ideas of reason. I then offer my rule‐based account of the regulative use of reason (...) by clarifying how Kant transforms reason's metaphysical inclinations into prescriptive rules of bottom‐up empirical research. Finally, I explain why such interpretation of reason is metaphysically innocent and thereby a promising approach to understand its role in Kant's scientific project. (shrink)
