A logic is called 'paraconsistent' if it rejects the rule called 'ex contradictione quodlibet', according to which any conclusion follows from inconsistent premises. While logicians have proposed many technically developed paraconsistent logical systems and contemporary philosophers like Graham Priest have advanced the view that some contradictions can be true, and advocated a paraconsistent logic to deal with them, until recent times these systems have been little understood by philosophers. This book presents a comprehensive overview on paraconsistent logical systems to change (...) this situation. The book includes almost every major author currently working in the field. The papers are on the cutting edge of the literature some of which discuss current debates and others present important new ideas. The editors have avoided papers about technical details of paraconsistent logic, but instead concentrated upon works that discuss more 'big picture' ideas. Different treatments of paradoxes takes centre stage in many of the papers, but also there are several papers on how to interpret paraconistent logic and some on how it can be applied to philosophy of mathematics, the philosophy of language, and metaphysics.

A counterpossible conditional is a counterfactual with an impossible antecedent. Common sense delivers the view that some such conditionals are true, and some are false. In recent publications, Timothy Williamson has defended the view that all are true. In this paper we defend the common sense view against Williamson’s objections.

Based upon the concept of Law qualified in Monarchia, II.50, Dante was not only a general philosopher (a lover of knowledge) as well as a political disputant in his times, but also his primary contribution (not always obvious) in legal speculation could be demonstrated. In fact, if his thought reflected the platonic ordo sapientiae through a deep intersection between téchne and episteme (phronesis) toward a linguistic koiné, could we say the same thing on his concept of justice as a rational (...) ars boni et aequi? This essay aims to depict Dante as legal theorist of his times and theorist of Justice beyond them, adopting the hermeneutical point of view, not just as an interest into textual interpretation but referring his use of language as form of life and his works an inexhaustible sources of education for legal philosophy.

Review of Ontology and Metaontology: A Contemporary Guide by Francesco Berto & Matteo Plebani.

The subject of my article is the principle of characterization – the most controversial principle of Meinong’s Theory of Objects. The aim of this text is twofold. First of all, I would like to show that Russell’s well-known objection to Meinong’s Theory of Objects can be reformulated against a new modal interpretation of Meinongianism that is presented mostly by Graham Priest. Secondly, I would like to propose a strategy which gives uncontroversial restriction to the principle of characterization and which allows (...) to avoid Russell’s argument. The strategy is based on the distinction between object- and metalanguage, and it applies to modal Meinongianism as well as to other so-called Meinongian theories. (shrink)

Achille Varzi è uno dei maggiori metafisici viventi. Nel corso degli anni ha scritto testi fondamentali di logica, metafisica, mereologia, filosofia del linguaggio. Ha sconfinato nella topologia, nella geografia, nella matematica, ha ragionato di mostri e confini, percezione e buchi, viaggi nel tempo, nicchie, eventi e ciambelle; e non ha disdegnato di dialogare con gli abitanti di Flatlandia, con Neo e con Terminator. Tra le sue opere principali: Holes and Other Superficialities e Parts and Places. The Structures of Spatial Representation, (...) entrambi scritti insieme a R. Casati per MIT Press; Il mondo messo a fuoco, Laterza; e il suo libro più recente: Le tribolazioni del filosofare, con C. Calosi, per Laterza. -/- Da una giornata all’Università di Urbino nasce questa conversazione a molte voci sulla e con la filosofia di Achille C. Varzi. In un dialogo critico al quale l’Autore si presta con generosità e onestà intellettuale, Andrea Borghini, Francesco Calemi, Claudio Calosi, Elena Casetta, Valeria Giardino, Pierluigi Graziani, Patrizia Pedrini, Daniele Santoro e Giuliano Torrengo lo interrogano e mettono alla prova sui temi affrontati, nel corso degli anni, in campi diversi. Il risultato è un percorso che si snoda attraverso molti mondi, dalla logica alla metafisica, dalla filosofia del linguaggio alla filosofia della matematica, dalla mereologia alla filosofia del tempo, spingendosi in qualche caso oltre i confini del saggio filosofico.

This paper attempts to look Francesco Gentile's concept of the Law under phenomenological point of view. Francesco Gentile (1936-2009) was full professor of Philosophy of Law at Padua University and Dean of School of Law; during his academic career, based on Roman Jurisprudentia and Christian message of Redemption, he developed a personal conception of law like "conversion the human conflict to interpersonal dispute". Then, in this paper, I want to observe this philosophical result, under biblical term "justification" connected (...) to Levinas' ethic, and I want to aim to revalue and exploit the problem of his systematic approach like a specific theory of Law.

It is always difficult to disentangle oneself from the changes in epoch-making cultural events that have taken place over several centuries. Freemasonry is an emblematic case. It was born around the seventeenth century and still exists in the twenty-first. The changes within it have been innumerable, showing that it is not a coherent and constant phenomenon in its evolution. There have been Masonic authors, of relevant presence in Western culture, who have nailed the fundamental principles of Masonic thought, of its (...) "doing" and of its "being": Gotthold Ephraim Lessing (1729 - 1781) and Johann Gottfried von Herder (1744 - 1803). Francesco Angioni explores the sometimes abyssal differences between a way of "thinking" about the Freemasonry of the two Authors and that of today. It is the critical research of understanding the differences between a Masonic thought built on solid foundations and the construction of multiple walls of composite architecture that is not characterized by a coherent project. ============== È sempre difficile districarsi tra i cambiamenti di eventi culturali epocali che si sono svolti nel corso di più secoli. La Massoneria è un caso emblematico. Essa nasce intorno al XVII secolo ed esiste ancora nel XXI. I cambiamenti al suo interno sono stati innumerevoli, palesando che non è un fenomeno coerente e costante nel suo evolversi. Ci sono stati Autori massonici, di rilevante presenza nella cultura occidentale, che hanno inchiodato i principi fondamentali del pensiero massonico, del suo "fare" e del suo "essere": Gotthold Ephraim Lessing (1729 – 1781) e Johann Gottfried von Herder (1744 – 1803). Francesco Angioni esplora le differenze talora abissali tra un modo di "pensare" la Massoneria dei due Autori e quello di oggi. È la ricerca critica di comprensione delle diversità tra un pensiero massonico edificato su solide fondamenta e la costruzione di molteplici mura di composita architettura che non si caratterizza per un progetto coerente.

We consider essential the need to integrate the causalistic nomothetic scientific approach with an unavoidable acausal finalistic approach. We come to consider too that it is precisely the psychoanalytic sphere that contributes decisively to this redefinition within the epistemology of science.

This paper investigates the link between the consumer perception that a company is socially oriented and the consumer intention to buy products marketed by that company. We suggest that this link exists when at least two conditions prevail: (1) the products sold by that company comply with ethical and social requirements; (2) the company has an acknowledged commitment to protect consumer rights and interests. To test these hypotheses, we conducted a survey among the clients of retail chains offering Fair Trade (...) products. The results show that socially oriented companies can successfully leverage their reputation to market products with high symbolic values. (shrink)

We present and defend the Australian Plan semantics for negation. This is a comprehensive account, suitable for a variety of different logics. It is based on two ideas. The first is that negation is an exclusion-expressing device: we utter negations to express incompatibilities. The second is that, because incompatibility is modal, negation is a modal operator as well. It can, then, be modelled as a quantifier over points in frames, restricted by accessibility relations representing compatibilities and incompatibilities between such points. (...) We defuse a number of objections to this Plan, raised by supporters of the American Plan for negation, in which negation is handled via a many-valued semantics. We show that the Australian Plan has substantial advantages over the American Plan. (shrink)

The fourteen papers in this collection offer a variety of original contributions to the epistemology of modality. In seeking to explain how we might account for our knowledge of possibility and necessity, they raise some novel questions, develop some unfamiliar theoretical perspectives, and make some intriguing proposals. Collectively, they advance our understanding of the field. In Part I of this Introduction, I give some general background about the contemporary literature in the area, by sketching a timeline of the main tendencies (...) of the past twenty-five years or so, up to the present debates. Next, I focus on four features that largely characterize the latest literature, and the papers in the present collection in particular: (i) an endorsement of the importance of essentialism; (ii) a shift to a “metaphysics-first” approach to modal epistemology; (iii) a focus on metaphysical modality as opposed to other kinds of modality; and (iv) a preference for non-uniform modal epistemology. In Part II, I present the individual papers in the volume. These are organized around the following four chapters, based on their topic: (A) Skepticism & Deflationism; (B) Essentialism; (C) Non-Essentialist Accounts; (D) Applications. -/- LIST OF CONTRIBUTORS: Francesco Berto; Stephen Biggs & Jessica Wilson; Justin Clark-Doane; Philip Goff; Bob Hale; Frank Jackson; Mark Jago; Boris Kment; Antonella Mallozzi; Graham Priest; Gabriel Rabin; Amie Thomasson; Anand Vaidya & Michael Wallner; Jennifer Wang. -/- The volume is dedicated to the memory of Bob Hale. -/- .

I want to model a finite, fallible cognitive agent who imagines that p in the sense of mentally representing a scenario—a configuration of objects and properties—correctly described by p. I propose to capture imagination, so understood, via variably strict world quantifiers, in a modal framework including both possible and so-called impossible worlds. The latter secure lack of classical logical closure for the relevant mental states, while the variability of strictness captures how the agent imports information from actuality in the imagined (...) non-actual scenarios. Imagination turns out to be highly hyperintensional, but not logically anarchic. Section 1 sets the stage and impossible worlds are quickly introduced in Sect. 2. Section 3 proposes to model imagination via variably strict world quantifiers. Section 4 introduces the formal semantics. Section 5 argues that imagination has a minimal mereological structure validating some logical inferences. Section 6 deals with how imagination under-determines the represented contents. Section 7 proposes additional constraints on the semantics, validating further inferences. Section 8 describes some welcome invalidities. Section 9 examines the effects of importing false beliefs into the imagined scenarios. Finally, Sect. 10 hints at possible developments of the theory in the direction of two-dimensional semantics.

We present a theory of truth in fiction that improves on Lewis's [1978] ‘Analysis 2’ in two ways. First, we expand Lewis's possible worlds apparatus by adding non-normal or impossible worlds. Second, we model truth in fiction as belief revision via ideas from dynamic epistemic logic. We explain the major objections raised against Lewis's original view and show that our theory overcomes them.

This book is both an introduction to and a research work on Meinongianism. “Meinongianism” is taken here, in accordance with the common philosophical jargon, as a general label for a set of theories of existence – probably the most basic notion of ontology. As an introduction, the book provides the first comprehensive survey and guide to Meinongianism and non-standard theories of existence in all their main forms. As a research work, the book exposes and develops the most up-to-date Meinongian theory (...) (called modal Meinongianism), applies it to specific fields, and discusses its open problems. Part I of the book provides a historical introduction to, and critical discussion of, the dominant philosophical view of existence: the “Kantian-Fregean-Quinean” perspective. Part II is the full-fledged introduction to the Meinongian theories of existence as a real property of individuals: after starting with the so-called naïve Meinongian conception and its problems, it provides a self-contained presentation of the main neo-Meinongian proposals, and a detailed discussion of their strengths and weaknesses. Part III develops a specific neo-Meinongian theory of existence employing a model-theoretic semantic framework. It discusses its application to the ontology and semantics of fictional objects, and its open problems. The methodology of the book follows the most recent trends in analytic ontology. In particular, the meta-ontological point of view is largely privileged. (shrink)

'Ontology and Metaontology: A Contemporary Guide' is a clear and accessible survey of ontology, focussing on the most recent trends in the discipline. -/- Divided into parts, the first half characterizes metaontology: the discourse on the methodology of ontological inquiry, covering the main concepts, tools, and methods of the discipline, exploring the notions of being and existence, ontological commitment, paraphrase strategies, fictionalist strategies, and other metaontological questions. The second half considers a series of case studies, introducing and familiarizing the reader (...) with concrete examples of the latest research in the field. The basic sub-fields of ontology are covered here via an accessible and captivating exposition: events, properties, universals, abstract objects, possible worlds, material beings, mereology, fictional objects. -/- The guide's modular structure allows for a flexible approach to the subject, making it suitable for both undergraduates and postgraduates looking to better understand and apply the exciting developments and debates taking place in ontology today.

The Humean view that conceivability entails possibility can be criticized via input from cognitive psychology. A mainstream view here has it that there are two candidate codings for mental representations (one of them being, according to some, reducible to the other): the linguistic and the pictorial, the difference between the two consisting in the degree of arbitrariness of the representation relation. If the conceivability of P at issue for Humeans involves the having of a linguistic mental representation, then it is (...) easy to show that we can conceive the impossible, for impossibilities can be represented by meaningful bits of language. If the conceivability of P amounts to the pictorial imaginability of a situation verifying P, then the question is whether the imagination at issue works purely qualitatively, that is, only by phenomenological resemblance with the imagined scenario. If so, the range of situations imaginable in this way is too limited to have a significant role in modal epistemology. If not, imagination will involve some arbitrary labeling component, which turns out to be sufficient for imagining the impossible. And if the relevant imagination is neither linguistic nor pictorial, Humeans will appear to resort to some representational magic, until they come up with a theory of a ‘third code’ for mental representations.

The concept of perversion has traditionally been applied particularly to the sexual sphere, in order to condemn certain desires and certain practices as wrong or inappropriate because of their unnaturalness, as they are understood as a deviation from a given function of sexuality. In this article, I explore the question whether and how such a concept could be applied to another central dimension of our existence, namely our death and, in particular, whether it makes sense to talk of perverted attitudes (...) towards (our own) death. In the first section I present a fairly common account of what is a perverted attitude towards sex and explain how that account can be used to define a perverted attitude towards death. I come up with four suggestions (one based on belief in the afterlife and three secular ones, based respectively on the notion of death as meaningless, on Heidegger’s concept of authenticity and on the evolutionary function of death). In the second section, I explore potential connections between perversion in sex and perversion in death. I conclude that, outside the Catholic worldview, perverted attitudes to sex do not bring along perverted attitudes towards death, nor is there a connection the other way around. In fact, certain kinds of perverted attitudes towards death are even inimical to sexual perversion. In the third section, I present a metaphysical and an ethical reason to doubt that we can and should talk of a function of death or sex. (shrink)

We propose a solution to the problem of logical omniscience in what we take to be its fundamental version: as concerning arbitrary agents and the knowledge attitude per se. Our logic of knowledge is a spin-off from a general theory of thick content, whereby the content of a sentence has two components: an intension, taking care of truth conditions; and a topic, taking care of subject matter. We present a list of plausible logical validities and invalidities for the logic of (...) knowledge per se for arbitrary agents, and isolate three explanatory factors for them: the topic-sensitivity of content; the fragmentation of knowledge states; the defeasibility of knowledge acquisition. We then present a novel dynamic epistemic logic that yields precisely the desired validities and invalidities, for which we provide expressivity and completeness results. We contrast this with related systems and address possible objections. (shrink)

Is there a notion of contradiction—let us call it, for dramatic effect, “absolute”—making all contradictions, so understood, unacceptable also for dialetheists? It is argued in this paper that there is, and that spelling it out brings some theoretical benefits. First it gives us a foothold on undisputed ground in the methodologically difficult debate on dialetheism. Second, we can use it to express, without begging questions, the disagreement between dialetheists and their rivals on the nature of truth. Third, dialetheism has an (...) operator allowing it, against the opinion of many critics, to rule things out and manifest disagreement: for unlike other proposed exclusion-expressing-devices (for instance, the entailment of triviality), the operator used to formulate the notion of absolute contradiction appears to be immune both from crippling expressive limitations and from revenge paradoxes—pending a rigorous nontriviality proof for a formal dialetheic theory including it.

It can be hard to see where money fits in the world. Money seems both real and imaginary, since it has obvious causal powers, but is also, just as obviously, something humans have just made up. Recent philosophical accounts of money have declared it to be real, but for very different reasons. John Searle and Francesco Guala disagree over whether money is just whatever acts like money, or just whatever people believe to be money. In developing their accounts of (...) institutions as a part of social reality, each uses money as a paradigm institution, but they disagree on how institutions exist. Searle argues that the institution of money belongs to an ontological level separate from the physical world, held up by the collective intentions of a group, while Guala claims that money is a part of the ordinary physical world and is just whatever performs a “money-like function” in a group, regardless of what that group believes about it. Here, we argue that any purely functional account like Guala’s will be unable to capture the distinctive phenomenon of money, since monetary transactions are defined by the attitudes transactors hold toward them. Money will be obscured or misidentified if defined functionally. As we go on to show by examining recent work by Smit et al., belief in money does not require taking on all of Searle’s ontological commitments, but money and mental contents will stand or fall together.

I propose a comprehensive account of negation as a modal operator, vindicating a moderate logical pluralism. Negation is taken as a quantifier on worlds, restricted by an accessibility relation encoding the basic concept of compatibility. This latter captures the core meaning of the operator. While some candidate negations are then ruled out as violating plausible constraints on compatibility, different specifications of the notion of world support different logical conducts for negations. The approach unifies in a philosophically motivated picture the following (...) results: nothing can be called a negation properly if it does not satisfy Contraposition and Double Negation Introduction; the pair consisting of two split or Galois negations encodes a distinction without a difference; some paraconsistent negations also fail to count as real negations, but others may; intuitionistic negation qualifies as real negation, and classical Boolean negation does as well, to the extent that constructivist and paraconsistent doubts on it do not turn on the basic concept of compatibility but rather on the interpretation of worlds. (shrink)

Accounts of propositions as sets of possible worlds have been criticized for conflating distinct impossible propositions. In response to this problem, some have proposed to introduce impossible worlds to represent distinct impossibilities, endorsing the thesis that impossible worlds must be of the same kind; this has been called the parity thesis. I show that this thesis faces problems, and propose a hybrid account which rejects it: possible worlds are taken as concrete Lewisian worlds, and impossibilities are represented as set-theoretic constructions (...) out of them. This hybrid account (1) distinguishes many intuitively distinct impossible propositions; (2) identifies impossible propositions with extensional constructions; (3) avoids resorting to primitive modality, at least so far as Lewisian modal realism does. (shrink)

We outline a neo-Meinongian framework labeled as Modal Meinongian Metaphysics (MMM) to account for the ontology and semantics of fictional discourse. Several competing accounts of fictional objects are originated by the fact that our talking of them mirrors incoherent intuitions: mainstream theories of fiction privilege some such intuitions, but are forced to account for others via complicated paraphrases of the relevant sentences. An ideal theory should resort to as few paraphrases as possible. In Sect. 1, we make this explicit via (...) two methodological principles, called the Minimal Revision and the Acceptability Constraint. In Sect. 2, we introduce the standard distinction between internal and external fictional discourse. In Sects. 3–5, we discuss the approaches of (traditional) Meinongianism, Fictionalism, and Realism—and their main troubles. In Sect. 6 we propose our MMM approach. This is based upon (1) a modal semantics including impossible worlds (Subsect. 6.1); (2) a qualified Comprehension Principle for objects (Subsect. 6.2); (3) a notion of existence-entailment for properties (Subsect. 6.3). In Sect. 7 we present a formal semantics for MMM based upon a representation operator. And in Sect. 8 we have a look at how MMM solves the problems of the three aforementioned theories. (shrink)

I present an approach to our conceiving absolute impossibilities—things which obtain at no possible world—in terms of ceteris paribus intentional operators: variably restricted quantifiers on possible and impossible worlds based on world similarity. The explicit content of a representation plays a role similar in some respects to the one of a ceteris paribus conditional antecedent. I discuss how such operators invalidate logical closure for conceivability, and how similarity works when impossible worlds are around. Unlike what happens with ceteris paribus counterfactual (...) conditionals, the closest worlds are relevantly closest belief-worlds: closest to how things are believed to be, rather than to how they are. Also, closeness takes into account apriority and the opacity of intentional contexts. (shrink)

We present a framework for epistemic logic, modeling the logical aspects of System 1 and System 2 cognitive processes, as per dual process theories of reasoning. The framework combines non-normal worlds semantics with the techniques of Dynamic Epistemic Logic. It models non-logically-omniscient, but moderately rational agents: their System 1 makes fast sense of incoming information by integrating it on the basis of their background knowledge and beliefs. Their System 2 allows them to slowly, step-wise unpack some of the logical consequences (...) of such knowledge and beliefs, by paying a cognitive cost. The framework is applied to three instances of limited rationality, widely discussed in cognitive psychology: Stereotypical Thinking, the Framing Effect, and the Anchoring Effect. (shrink)

The development of manufacturing technologies for new materials involves the generation of a large and continually evolving volume of information. The analysis, integration and management of such large volumes of data, typically stored in multiple independently developed databases, creates significant challenges for practitioners. There is a critical need especially for open-sharing of data pertaining to engineering design which together with effective decision support tools can enable innovation. We believe that ontology applied to engineering (OE) represents a viable strategy for the (...) alignment, reconciliation and integration of diverse and disparate data. The scope of OE includes: consistent capture of knowledge pertaining to the types of entities involved; facilitation of cooperation among diverse group of experts; more effective ongoing curation, and update of manufacturing data; collaborative design and knowledge reuse. As an illustrative case study we propose an ontology focused on the representation of composite materials focusing in particular on the class of Functionally Graded Materials (FGM) in particular. The scope of the ontology is to provide information about the components of such materials, the manufacturing processes involved in creation, and diversity of application ranging from additive manufacturing to restorative dentistry. The ontology is developed using Basic Formal Ontology (BFO) and the Ontology for Biomedical Investigations (OBI). (shrink)

Questo lavoro propone un confronto tra diversi strumenti utilizzabili per modellare la conoscenza di dominio in ambito didattico: le mappa concettuali, Novak e Cañas (2006), (uno strumento tradizionalmente utilizzato nelle scuole) e le ontologie computazionali (dei sistemi formali di modellazione concettuale, attualmente molto usati nei sistemi di intelligenza artificiale per le loro capacità di “ragionamento automatico”, si veda Guarino, (1995)). Nello specifico, questo articolo presenta il risultato di un un doppio esperimento sul campo condotto presso il Liceo Scientifico “Guido Parodi” (...) di Acqui Terme in cui gruppi di studenti paragonano lo strumento della mappa concettuale e quello dell’ontologia nella risoluzione di due problemi di “misconcezione” (o errata concettualizzazione): uno indotto attraverso la consegna di appunti e materiali didattici contenenti informazioni volontariamente contraddittorie tra loro (caso che potrebbe corrispondere alla situazione in cui uno studente prende - per qualche motivo - degli appunti in modo scorretto) e l’altro legato ad una complessità concettuale intrinseca all’argomento.

In this paper we reply to arguments of Kroon (“Characterization and Existence in Modal Meinongianism”. Grazer Philosophische Studien 86, 23–34) to the effect that Modal Meinongianism cannot do justice to Meinongian claims such as that the golden mountain is golden, and that it does not exist.

Philosophical dialetheism, whose main exponent is Graham Priest, claims that some contradictions hold, are true, and it is rational to accept and assert them. Such a position is naturally portrayed as a challenge to the Law of Non-Contradiction (LNC). But all the classic formulations of the LNC are, in a sense, not questioned by a typical dialetheist, since she is (cheerfully) required to accept them by her own theory. The goal of this paper is to develop a formulation of the (...) Law which appears to be unquestionable, in the sense that the Priestian dialetheist is committed to accept it without also accepting something inconsistent with it, on pain of trivialism—that is to say, on pain of lapsing into the position according to which everything is the case. This will be achieved via (a) a discussion of Priest's dialetheic treatment of the notions of rejection and denial; and (b) the characterization of a negation via the primitive intuition of content exclusion. Such a result will not constitute a cheap victory for the friends of consistency. We may just learn that different things have been historically conflated under the label of 'Law of Non-Contradiction'; that dialetheists rightly attack some formulations of the Law, and orthodox logicians and philosophers have been mistaken in assimilating them to the indisputable one.

An interpretation of Wittgenstein’s much criticized remarks on Gödel’s First Incompleteness Theorem is provided in the light of paraconsistent arithmetic: in taking Gödel’s proof as a paradoxical derivation, Wittgenstein was drawing the consequences of his deliberate rejection of the standard distinction between theory and metatheory. The reasoning behind the proof of the truth of the Gödel sentence is then performed within the formal system itself, which turns out to be inconsistent. It is shown that the features of paraconsistent arithmetics match (...) with some intuitions underlying Wittgenstein’s philosophy of mathematics, such as its strict finitism and the insistence on the decidability of any mathematical question.

Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

I examine and rebut Ridge’s two arguments for Capacity Judgment Internalism (simply qua their particular character and content, first person normative judgments are necessarily capable of motivating without the help of any independent desire). First, the rejection of the possibility of anormativism (sec. 2), second, an argument from the rational requirement to intend to do as one judges that one ought to do (sec. 3).

Models of discourse and narration elaborated within the classical compositional framework have been characterized as bottom-up models, according to which discourse analysis proceeds incrementally, from phrase and sentence local meaning to discourse global meaning. In this paper we will argue against these models. Assuming as a case study the issue of discourse coherence, we suggest that the assessment of coherence is a top-down process, in which the construction of a situational interpretation at the global meaning level guides local meaning analysis. (...) In support of our hypothesis, we explore the role of executive functions (brain functions involved in planning and organization of goal-oriented behaviors) in coherence’s establishment, discussing the results of several studies on narrative abilities of patients with brain injuries. We suggest that, compared to other models of discourse processing focused on comprehension, our model is a viable candidate for an integrated account of discourse comprehension and production.

We address an argument by Floridi (Synthese 168(1):151–178, 2009; 2011a), to the effect that digital and analogue are not features of reality, only of modes of presentation of reality. One can therefore have an informational ontology, like Floridi’s Informational Structural Realism, without commitment to a supposedly digital or analogue world. After introducing the topic in Sect. 1, in Sect. 2 we explain what the proposition expressed by the title of our paper means. In Sect. 3, we describe Floridi’s argument. In (...) the following three sections, we raise three difficulties for it, (i) an objection from intuitions: Floridi’s view is not supported by the intuitions embedded in the scientific views he exploits (Sect. 4); (ii) an objection from mereology: the view is incompatible with the world’s having parts (Sect. 5); (iii) an objection from counting: the view entails that the question of how many things there are doesn’t make sense (Sect. 6). In Sect. 7, we outline two possible ways out for Floridi’s position. Such ways out involve tampering with the logical properties of identity, and this may be bothersome enough. Thus, Floridi’s modus ponens will be our (and most ontologists’) modus tollens. (shrink)

Il breve saggio si propone di esaminare la centralità della figura materna nell’opera di un ingegnoso costruttore di storie della letteratura italiana del Novecento: Alberto Moravia. La scelta dell’Autore nasce dalla rilevanza della tematica nella sua opera, in cui peraltro è quasi sempre assente il punto di vista femminile delle “voci” delle donne. Ciò sembra paradossale e questa circostanza è di grande interesse critico. In particolare, a dispetto delle interpretazioni più canoniche, secondo cui Moravia – negli scritti realizzati tra il (...) 1929 e il 1964 – ha inteso compiere una “distruzione” dell’immagine materna nel quadro di una visione pessimista della famiglia borghese, dovremo considerare un più complesso e articolato universo materno nello scrittore romano, in cui è possibile ricostruire cinque modelli – la “madre autoritaria”, la “madre-non madre”, la “madre padrona”, la “madre-angelo custode” e la “madre-seduttrice” –, ben esemplificati nei principali romanzi ma che si ritrovano nei racconti che Moravia scrive ininterrottamente dagli anni Trenta agli anni Sessanta, la cui mole ha determinato, ancor oggi, una mancanza di studi sistematici. In secondo luogo, la tematica della madre sarà esaminata nelle trasposizioni cinematografiche italiane delle opere letterarie di Moravia. Va ricordato che il rapporto dello scrittore con il cinema fu particolarmente intenso. Per un verso, la “settima arte” rivestì un ruolo non secondario nella formazione ed esperienza estetica dell’Autore romano, che al cinema si interessò anche professionalmente nelle vesti di critico cinematografico, a partire dal primo dopoguerra, dapprima, per La nuova Europa e Libera stampa, poi, per L’Europeo e L’Espresso, a cui dobbiamo aggiungere l’attività di saggista per numerose riviste specializzate. Per altro verso, il cinema italiano non solo ha attinto a “mani basse” dall’opera di Moravia per sceneggiature di pellicole, che furono pietre miliari della sua storia. L’elenco dei romanzi e racconti adattati al grande schermo rende conto della grande influenza nella cultura italiana degli anni Cinquanta e Sessanta: La provinciale (1953) di Mario Soldati, La romana (1954) di Luigi Zampa, Peccato che sia una canaglia (1954) di Alessandro Blasetti, Racconti romani (1955) di Gianni Franciolini, La ciociara (1960) di Vittorio de Sica, La giornata balorda (1960) di Mauro Bolognini, Risate di gioia (1960) di Mario Monicelli, Agostino (o la perdita dell’innocenza) (1962) di Mauro Bolognini, La noia (1963) di Damiano Damiani, Gli indifferenti (1964) di Francesco Maselli, Le ore nude (1964) di Marco Vicario, La donna invisibile (1969) di Paolo Spinola, Una ragazza piuttosto complicata (1969) di Damiano Damiani, L’amore coniugale (1970) di Dacia Maraini, Il conformista (1970) di Bernardo Bertolucci, e molti altri ancora. Come avremo modo soltanto di accennare, il successo della letteratura moraviana nel mondo del cinema italiano si deve a molteplici fattori, tra cui la raffigurazione dei personaggi e degli ambienti, la focalizzazione su certe tematiche e, non da ultimo, lo stile narrativo, particolarmente adatto alle trasposizioni cinematografiche. Come caso di studio, ci soffermeremo, infine, sulla figura materna della versione filmica de La noia di Damiani, con l’obiettivo di verificare se nel passaggio dal libro alla pellicola, quella particolare connotazione della madre autoritaria abbia subito delle alterazioni. L’ipotesi che muove l’analisi è che la stesura delle sceneggiature, la raffigurazione dei personaggi e la messa in scena delle sequenze filmiche facciano emergere un riadattamento adeguato al largo pubblico, con il sovvertimento dell’andamento cronologico, alcune “lacune” di ordine psicologico nella raffigurazione dei protagonisti e un certo cedimento moralistico alla cultura ancora dominante negli anni ’50 e ’60, in cui la figura materna, sia quando è incattivita dalla povertà che quando è inaridita dalla ricchezza, anela comunque agli affetti familiari, trovando in essi una qualche forma di redenzione.

In his famous work on vagueness, Russell named “fallacy of verbalism” the fallacy that consists in mistaking the properties of words for the properties of things. In this paper, I examine two (clusters of) mainstream paraconsistent logical theories – the non-adjunctive and relevant approaches –, and show that, if they are given a strongly paraconsistent or dialetheic reading, the charge of committing the Russellian Fallacy can be raised against them in a sophisticated way, by appealing to the intuitive reading of (...) their underlying semantics. The meaning of “intuitive reading” is clarified by exploiting a well-established distinction between pure and applied semantics. If the proposed arguments go through, the dialetheist or strong paraconsistentist faces the following Dilemma: either she must withdraw her claim to have exhibited true contradictions in a metaphysically robust sense – therefore, inconsistent objects and/or states of affairs that make those contradictions true; or she has to give up realism on truth, and embrace some form of anti-realistic (idealistic, or broadly constructivist) metaphysics. Sticking to the second horn of the Dilemma, though, appears to be promising: it could lead to a collapse of the very distinction, commonly held in the literature, between a weak and a strong form of paraconsistency – and this could be a welcome result for a dialetheist.

In this paper, I would like to show how the movements of never stable meanings that link biography and religion are figured and interwoven throughout a kind of ineffable literary and philosophical notion of religion. Religion is a notion that can be understood through a cluster of topics such as origin, promise, dissociation, the unconditional, forgiveness, the undeconstructable and the possibility of the impossible—terms and expressions that Derrida suggests describe God.

The intuition of neutrality, as discussed by John Broome, says that the addition of people does not, by itself, produce or subtract value from the world. Such intuition allows us to disregard the effects of climate change policy onto the size of populations, effectively allowing us to make policy recommendations. Broome has argued that the intuition has to go. Orsi responds by urging a normative (rather than Broome's axiological) interpretation of neutrality in terms of an exclusionary permission to disregard the (...) value of adding lives. He explores justifications and limits of such permission by referring to the prospect of human extinction. (shrink)

In this article we explore the relationship between consciousness and the unconscious as it has taken shape within contemporary cognitive science - meaning by this term the mature cognitive science, which has fully incorporated the results of the neurosciences. In this framework we first compare the neurocognitive unconscious with the Freudian one, emphasizing the similarities and above all the differences between the two constructs. We then turn our attention to the implications of the centrality of unconscious processes in cognitive science (...) for the classical conception of the self. Our analysis will bring to light a bit of claustrophobic dialectic between an eliminative variety of naturalism and an anti-naturalistic form of hermeneutics. Hence we conclude by recommending the pursuit of a mediation between such extreme stances. (shrink)

Sometimes mereologists have problems with counting. We often don't want to count the parts of maximally connected objects as full-fledged objects themselves, and we don't want to count discontinuous objects as parts of further, full-fledged objects. But whatever one takes "full-fledged object" to mean, the axioms and theorems of classical, extensional mereology commit us to the existence both of parts and of wholes – all on a par, included in the domain of quantification – and this makes mereology look counterintuitive (...) to various philosophers. In recent years, a proposal has been advanced to solve the tension between mereology and familiar ways of counting objects, under the label of Minimalist View . The Minimalist View may be summarized in the slogan: "Count x as an object iff it does not overlap with any y you have already counted as an object". The motto seems prima facie very promising but, we shall argue, when one looks at it more closely, it is not. On the contrary, the Minimalist View involves an ambiguity that can be solved in quite different directions. We argue that one resolution of the ambiguity makes it incompatible with mereology. This way, the Minimalist View can lend no support to mereology at all. We suggest that the Minimalist View can become compatible with mereology once its ambiguity is solved by interpreting it in what we call an epistemic or conceptual fashion: whereas mereology has full metaphysical import, the Minimalist View may account for our ways of selecting "conceptually salient" entities. But even once it is so disambiguated, it is doubtful that the Minimalist View can help to make mereology more palatable, for it cannot make it any more compatible with commonsensical ways of counting objects.

The aim of this article is to show how both Jan Patočka and Jürgen Habermas, starting from a reinterpretation of the idea of «lifeworld», engaged a critique of modern civilisation, aiming (with different outcomes) at a redefinition of the concept of political community. In order to achieve this goal, I firstly focus on Patočka’s understanding of modern rational civilisation and its attempt to fix the fracture between «life» and «world». At this stage, I take also advantage of Hans Blumenberg’s distinction (...) between these two terms, in order to better clarify Patočka’s stance on this problem. Secondly, I analyse Habermas’ ideas of lifeworld and system, and their uncoupling in modern societies, as well as the reemergence of this issue in Habermas’ recent works on the European economic and political crisis. Finally, I focus on the very different ways in which Patočka and Habermas tackled the ideas of conflict and crisis in contemporary world, also in view of a possible path out of this crisis through a re-constitution of Europe.

Should positional sexual misconduct (sexual advances or interaction where one party is known, or should be known, to have a significant power over the other) be included in the list of morally forbidden behaviours? I explore benefits and costs of this moral reform with the help of J. S. Mill.

Meta-ontology (in van Inwagen's sense) concerns the methodology of ontology, and a controversial meta-ontological issue is to what extent ontology can rely on linguistic analysis while establishing the furniture of the world. This paper discusses an argument advanced by some ontologists (I call them unifiers) against supporters of or coincident entities (I call them multipliers) and its meta-ontological import. Multipliers resort to Leibniz's Law to establish that spatiotemporally coincident entities a and b are distinct, by pointing at a predicate F (...) () made true by a and false by b . Unifiers try to put multipliers in front of a dilemma: in attempting to introduce metaphysical differences on the basis of semantic distinctions, multipliers either (a) rest on a fallacy of verbalism, entailed by a trade-off between a de dicto and a de re reading of modal claims, or (b) beg the question against unifiers by having to assume the distinction between a and b beforehand. I shall rise a tu quoque, showing that unifiers couldn't even distinguish material objects (or events) from the spatiotemporal regions they occupy unless they also resorted to linguistic distinctions. Their methodological aim to emancipate themselves from linguistic analysis in ontological businesses is therefore problematic. (shrink)

The “sign of consequence” is a notation for propositional logic that Peirce invented in 1886 and used at least until 1894. It substituted the “copula of inclusion” which he had been using since 1870.

This study draws a comparative framework between deconstructive reading of texts and jazz standards. It will be argued that both are defined by the constant play of tradition and innovation. On the one hand, the repetition of a set of rules and dominant understanding of texts/tunes that generates tradition. On the other hand, invention and improvisation that take on that tradition and generate innovation. The act of reading/playing becomes also an act of invention/improvisation that manifests a constant tension between the (...) old that is handed down through writing/recording and the new that is generated by the reader/musician.
