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.

Scopo di questo agile ma denso volume è approfondire “The part played by the mathematical construction in the context of a full investigation of Kant’s theory of sensibility, that to say the Transcendental Aesthetic”. Si tratta della ripresentazione della tesi di dottorato della Shabel, da cui la stessa ha riportato ampi squarci per un articolo award-winning 1998 dal titolo ”Kant on the Symbolic Construction of Mathematical Concepts” (Studies in the History and the Philosophy of Science). Non si tratta di un (...) saggio di circostanza, bensì del risultato di un'attenta e approfondita ricerca sul ruolo della costruzione di concetti, come praticata e intesa in matematica al tempo di Kant e che sicuramente influenzò la stesura dell’Estetica Trascendentale.

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.

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.

'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.

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)

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 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.

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.

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)

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)

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)

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.

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.

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.

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.

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)

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 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)

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). I conclude with a few remarks about the nature of this requirement and about verdicts of (...) akrasia. (sec. 4). (shrink)

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.

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)

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.

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)

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)

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.

Francesco Angioni esplora le differenze talora abissali tra un modo di "pensare" la Massoneria dei due Autori e quello di oggi.

Despite the persistent reference to the Baconian Solomon House, the (...) Society did not impose or support a common programme of research in the field of the natural history of the Earth. (shrink)

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.

Only ten years since Derrida’s death, with critical detachment, is it possible to be in touch with him again, to start from the beginning of his philosophizing in company with Plato, and from this vantage point to re-read Dissemination? What really stands between Plato and Derrida? In the first page of Pharmacia Derrida writes: “We will take off here from the Phaedrus ... Only a blind or grossly insensitive reading, could indeed spread the rumour that Plato was simply condemning the (...) writer’s activity”.1 Hence the question: Is the nexus writing/pharmakon profitable for thinking of something ambivalent and irreducible, present and absent, something bearer of indefinitely deferred presence in the play of infinite real or imaginary substitutions? The main enterprise of this essay orbits about the problematic of writing, understood as τέχνη, but also as a key locus of relation Plato/ Derrida. Here technology - and thinking of its function and value- I would like to argue, regards the technical and non-technical, the practical and theoretical, seeing that thinking of their function remains always a “parasitical contamination”, seeing that writing is another speech, and, according this statement, we may regard Plato as he who paves the way for Derrida. In what follows, through textual analysis I will focus on some interesting unrolling, connected and disconnected threads by discussing the readings of different scholars and philosophers such as the disputed classicist E. A. Havelock, the historians of ancient philosophy G. Reale and C. H. Kahn. In particular I will explore, first, the nexus speech/writing, and argue that historically Plato was a bi-medial philosopher and writer, an aspect taken for granted, but not sufficiently attended by scholarship. In the second part of the essay I hold that the Derridean reading of ‘Plato’s Pharmacy’ discovers a special deconstruction at work within Plato’s dialogues. In the light of the manifold τέχνη, and of the hybrid Khora, at the end the apparent ambiguity in Plato’s stance and Derrida’s φάρμακον invites us to identify Plato as the Father of deconstruction.

Letters exchanged by scientists are a crucial source by which to trace the process that accompanies their scientific evolution.

In the 20th century among the greatest philosophers and literates there was an ample, ideal, wide ranging forum on the question of Europe to which, following a run already started by F. Nietzsche, M. Heidegger, E. Husserl, P. Valéry, Ortega y Gasset, Nikolaj Berdjaev, and after the second world war G. Gadamer, J. Habermas, J. Derrida and others offered meaningful contributions. The questions were: What will be of the spirit of Europe? What will be of Europe? Europe: quo vadis? The (...) aim of this paper is to articulate the meaningful stages of this historical forum through some essays of mentioned philosophers and literates. The first essay is the conference "Europa und die deutsche Philosophie”, delivered by Heidegger in Rome 1936 at the Kaiser-Wilhelm-Institut, the same year of the publication of Husserl’s Krisis. Thereafter, with the purpose of marking a clear discontinuity between the debate of the first half of the century and the second, I comment on Gadamer’s essay “Europa und die oikoumene”, published half a century after the conference of Heidegger, then the Gadamer’s essay "Das Erbe Europas”, 1989, in which Gadamer deduces on the existential condition of Europeans, today. At the end, I analyze Derrida’s pamphlet "L'autre cap suivi de la démocratie ajournie", English version “The Other Heading: Reflection on Today’s Europe”, that opens with the provocative and heretical Derridean gesture: To which concept, to what real individual, to what entity can we confer today the name of Europe?

At a distance of more ten years from publication (2000 French/2005 English translation), with this essay I will re-read, comment and discuss, in different way and in form of anthological sketch, the Derridean volume ‘On Touching-Jean Luc Nancy’, focusing in particular on its ‘tangents and its metonymies’, its manifold entanglements with the metaphysics of touch and bodily connections. Making use of the geometrical figure of the tangent, Derrida affirms that "[if] philosophy has touched the limit [my emphasis-J. D. ]. of (...) the ontology of subjectivity, this is because philosophy has been led to this limit”. To touch is to touch a limit, a limit without depth or surface. How have we regarded touching in the past? The body? My thesis is that if Derridean reflection remains mostly anchored to Jean-Luc Nancy’s Corpus, it is inspired nevertheless by a different deconstructive gesture/s similar to different geometric tangents (the deconstructive practice is similar to the tracing of many tangents). Discussing in particular Nancy’s Dis-Enclosure: The Deconstruction of Christianity, Derrida’essay ‘Deconstruction of Christianity’ and devoting an entire section of the book to the sense of touch in the Gospels, Derrida gives us numerous and special considerations on deconstruction and the deconstruction of touch in Christianity, admitting as well the enormity of this task. A reflection on the Kas Saghafi, “Safe, Intact”: Derrida, Nancy, and the “Deconstruction of Christianity” will follow in an exemplary way. Following a discussion of touch and the body in both animal and human spheres, in the closing section of the essay, I will comment on the Patrick Llored’s essay A Philosophy of Touching Between the Human and the Animal: The Animal Ethics of Jacques Derrida, recently published in A Companion to Derrida (2014). This study addresses highly topical questions such as: ‘What does it teach us about touch, but also about the body and the life of the animal? To what extent is it capable of renewing our knowledge [connaissance] of non-human life and of generating an animal ethics reconceived from top to bottom? If touching is coextensive with the living body, that implies not only that we place the haptical question at the centre of reflection on the animal, but also that we take into account the consequence that is most disruptive for us today (A Companion, p. 512). And conclude along with Patrick Llored that the question of touch promises to transform everything we have understood until now about animality. (shrink)

In Politics of Friendship, the aporias of friendship transposed to democracy indicate that if democracy is a promise of the universal inclusiveness of each singular one counting equally, and if its fraternal or national limitation naturalizes the ineluctable decision of inclusion and exclusion, then true friendship requires dis-proportion. It demands a certain rupture in reciprocity and equality, as well as the interruption of all fusion between the you and the me. In this way democracy remains an un-fulfillable promise. In what (...) follows, an imaginary voyage to Europe inspired by the so-called Syracuse-paradigm, by means of a close reading of Derrida‘s The Other Heading: Reflections on Today's Europe, a sort of ’untimely meditation’ a la Nietzsche, I critically argue that Derrida’s idea of European identity, begotten by the irruption of the other, involves the radical other as a force that shows the limits of identity and of the self. Re-viewed, revisited and re-thought in the optic of the deconstructive standpoint, The Other Heading acquires a new light focusing on the possible/impossible relation between the political and the ethical (the Other Heading, i.e. democracy to come, Europe to come). The deconstructive standpoint I use here falls within the well known Derrida’s binary conception that undergird his way of thinking: presence/absence, speech/writing, and so forth. (shrink)

In searching for the origin of Europe and the cultural region/continent that we call “Europe”, at first glance we have to consider at least a double view: on the one hand the geographical understanding which indicates a region or a continent. On the other a certain form of identity and culture described and defined as European. Rodolphe Gasché taking hint from Husserl’s passage ‘Europe is not to be construed simply as a geographical and political entity’ states that a rigorous engagement (...) with what we understand by “Europe” requires that we acknowledge it as involving ‘something else as well’. With regard to the many bequests of Europe, founded in ancient Greece, in this essay I will attempt to elucidate some essential features of its cultural identity such as science and philosophy, and reflect upon several specific aspects: on the origin of Europe, on its roots and heritage, on the concept of culture, and especially on the foundation of sciences (Geometry), which contains a large part of European spirit and civilization. In particular I will address some European historical moments with reference to Husserl, Heidegger, the concept of Thaumazein… In the second part of the essay, I will shift my interest to Ancient Greece in order to access to the value of the Esprit de géométrie as defined in Proclus on the Commentary on the First Book of Euclid’s.

After a discussion of the fundamental tropes of Rorty’s philosophy, in and beyond Philosophy and the Mirror of Nature, and after describing an imaginary conversation between Rorty, Heidegger, Derrida, and Dewey, the paper- a sort of monography in a nutshell- aims to shed new light on the strategic figure of the ironist as developed by Rorty in Contingency, Irony, and Solidarity. Who really is the Rortyan ironist? A comparison between the ironist and the Platonic character of Callicles clearly shows that (...) Rorty’s irony does not correspond to Socratic or Platonic irony. From a close reading of relevant texts three ideas emerge: first, one can take an ironic stance despite its ability to support divergent metaphysical premises –Callicles is ironic in tone but foundationalist in metaphysics- while Rorty’s pragmatist appears ironic in tone and anti-foundationalist in metaphysics. Second, Callicles is a sort of public ironist; he feels pathos for the demos and the Athenian popular assembly, while the Rorty’s ironist appears as a private ironist looking for a hypothetical and detached conversation. And third, from the theatrical and literary point of view, Rorty’s ironist lacks the Greek character, the Greek mask, and Greek comicality. (shrink)

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.

Goethe, an important figure in 18th century German Freemasonry, developed a Masonic thought based on the assumptions of hermetic esotericism that influenced much of his poetic and scientific production. ===================Goethe importante figura della massoneria tedesca del XVIII secolo sviluppa un pensiero massonico fondato sui presupposti dell'esoterismo ermetico che influì su molta della sua produzione poetica e scientifica.

Initiatory symbology collects various forms of symbols: those that belong to an ancient tradition and that present themselves as a normalization of the past in a modernized key; those that derive from a pact between the members of the initiatory community and that guarantee the unity of the group, which are synchronized within the group itself; those that have the sense of projection to overcome the gnoseological limits of the group and its members, are traditional but through their character of (...) semantic multiplicity offer new gnoseological opportunities. Silence is not part of the first category, because not all ancient or traditional initiatory groups used it ritually or considered it as a symbol and therefore could not have a normative function susceptible to modernization. It can be a crucial moment of the second when it is ritualized in the different phases of learning on the basis of an agreement connected to the creation of the ritual and forming itself as one of the synchronic fulcrums of the group, ensuring its unity. It can also belong to the third case when it takes on a traditional guise but having its own multidimensional semantics, in the communion of saying and silent pulses of new opportunities for initiatory growth. Silence in the initiatory context is a specific linguistic form that characterizes the entire path of the initiates. Within the group, they elaborate the syntax of silence, the morphology of tacitly expressed symbols, without fully explaining their meanings. Each symbol, or sign in the semiotic sense, has different meanings for the different phases of the initiation process. Each one belongs to a different type of relationship with what it refers to: it has a relationship of "similarity" such as the design of a team and compass that illustrates operational objects, of "proximity" when it manifests the operation of measuring and relating the relationships for which the object is intended, of "concordance" if it refers to the object within the knowledge of an architectural rule. The symbol as a special form of sign manifests itself (first phase of learning), as in the example, in iconographic-descriptive mode containing a meaning "dictated". It is an initiatory dictatio to be kept in silence in front of the essoteric world, of which the initiating is still permeated, the symbolism must be evoked without making explicit its intimate meanings, it is described but not fully exposed. It is the evocative, indeterminate and silent value that must stimulate the initiating in the search for meanings. The indetermination of silence destructures the essoteric, its thought its categories, criteria and values, leads to the desert of essoteric meanings as a way to the ontology of initiatory language. It is a stage of waiting, of referral to another world. We suspect meanings that in the next phase begin to manifest themselves in a more precise dictatio, a functional dictamen to represent the concept of measurement in its multiple meanings where the measure is assumed as symbolic-conceptual abstraction. Continuing, the sign in the form of an object strips itself of any factual and existential reference, of the communication of an abstraction or conceptual ideation and unmasks itself in its being an initiatory "rule". It is assumed, therefore, that initiatory improvement passes through the understanding of the signs, an understanding that is increasingly deeper and more comprehensive and that is autonomous and independent of the signs of the exoteric world. With regard to the symbolic-initiatic language, learning, from the apprenticeship phase to the following phases, focuses on the study of the formal relationships of symbols within initiatory gnoseology, on the meanings inherent in symbols and on their relationship with the initiatory community.

La simbologia iniziatica raccoglie varie forme di simboli: quelli che appartengono a un’antica tradizione e che si ripresentano come una normalizzazione del passato in chiave modernizzata; quelli che derivano da un patto tra i membri della collettività iniziatica e che garantiscono l’unità del gruppo, che sono sincronici nell’ambito del gruppo stesso; quelli che hanno il senso di proiezione al superamento dei limiti gnoseologici del gruppo e dei suoi membri, sono tradizionali ma mediante il loro carattere di molteplicità semantica offrono nuove (...) opportunità gnoseologiche. Il silenzio non fa parte della prima categoria, perché non tutti i gruppi iniziatici antichi o tradizionali lo utilizzavano ritualmente o lo consideravano come simbolo e quindi non poteva avere una funzione normativa suscettibile di modernizzazione. Può essere momento cruciale del secondo quando viene ritualizzato nelle diverse fasi d’apprendimento sulla base di una pattuizione connessa alla creazione del rituale e costituendosi come uno dei fulcri sincronici del gruppo, assicurando la sua unitarietà. Può anche appartenere al terzo caso quando assume una veste tradizionale ma avendo una sua pluridimensionalità semantica, nella comunione del dicere e tacere pulsa di opportunità nuove per l’accrescimento iniziatico. Il silenzio nel contesto iniziatico è una forma linguistica specifica che caratterizza tutto il percorso degli iniziati. Questi elaborano all’interno del gruppo la sintassi del silenzio, la morfologia dei simboli espressi tacitamente, senza spiegare compiutamente i loro significati. Ogni simbolo, o segno in senso semiotico, ha delle diverse significazioni per le diverse fasi del percorso iniziatico. Ognuno appartiene a una diversa tipologia di rapporto con ciò a cui si riferisce: ha rapporto di “similarità” come il disegno di una squadra e compasso che illustra degli oggetti operativi, di “prossimità” quando manifesta l’operazione di misurazione e di relazione dei rapporti alla quale l’oggetto è destinato, di “concordanza” se rinvia all’oggetto dentro la cognizione di una regola architettonica. Il simbolo in quanto forma speciale di segno si manifesta (prima fase d’apprendimento), come nell’esempio, in modalità iconografico-descrittiva contenente un significato “dettato”. È una dictatio iniziatica da tenere nel silenzio di fronte al mondo essoterico , del quale l’iniziando è ancora permeato, la simbologia deve essere evocata senza esplicitarne i suoi intimi significati, la si descrive ma non la si espone compiutamente. È il valore evocativo, indeterminato e silenziato, che deve stimolare l’iniziando alla ricerca dei significati. L’indeterminazione del silenzio destruttura l’essoterico, il suo pensiero le sue categorie criteri e valori, porta al deserto dei significati essoterici come via all’ontologia del linguaggio iniziatico. È stadio di attesa, di rinvio a un mondo altro. Si sospettano dei significati che nella successiva fase incominciano a palesarsi in una dictatio più precisa, un dictamen funzionale a rappresentare il concetto di misurazione nelle sue plurime significanze ove la misura è assunta come astrazione simbolico-concettuale. Proseguendo, il segno in forma di oggetto si spoglia di ogni rimando fattuale ed esistenziale, di comunicazione di un’astrazione o ideazione concettuale e si smaschera nel suo essere “regola” iniziatica.

In Germany, between the last decades of the 18th and the first decades of the 19th centuries, four fundamental figures of German and European culture emerged: Lessing the great playwright, Herder the promoter of the epistemological foundations of modern linguistics and of the emerging historical-social sciences, Goethe the supreme poet and novelist, and Fichte the eminent philosopher. They were all Freemasons and basic authors of Masonic thought. The most significant works of these authors have been chosen, which summarize the interpretative (...) modalities of the complex Masonic reality of the 18th century. The book analyses Lessing's five Dialogues for Freemasons, highlighting his austere vision in the search for the essence of Freemasonry. Of Herder's two Masonic Dialogues, the connotation in the sense of Humanity of a Freemasonry that leaves the Enlightenment to set out towards new goals of pure and spiritual thought is noted. Among Goethe's poetic works, two in particular highlight the depth of a Masonic thought pervaded by a sophisticated and modern hermeticism. Fichte's Lessons on Freemasonry are framed in his complex philosophical thought and in his complicated experience of Masonic life. ========== Nella Germania tra gli ultimi decenni del XVIII e i primi del XIX secolo emergono quattro figure fondamentali della cultura tedesca ed europea: Lessing il grande drammaturgo, Herder promotore delle basi epistemologiche della moderna linguistica e delle nascenti scienze storico-sociali, Goethe il sommo poeta e romanziere, Fichte l’eminente filosofo. Erano tutti Massoni e autori basilari del pensiero massonico. Di questi Autori sono state scelte le opere più significative che sintetizzano le modalità interpretative della complessa realtà massonica del ‘700. Nel libro si analizzano i cinque Dialoghi per Massoni di Lessing evidenziando la sua visione austera nella ricerca dell’essenza della Massoneria. Dei due Dialoghi massonici di Herder è rilevata la connotazione nel senso dell’Humanität di una Massoneria che esce dall’Illuminismo per avviarsi a nuove mete di pensiero puro e spirituale. Tra le opere poetiche di Goethe due in particolare evidenziano la profondità di un pensiero massonico pervaso di un sofisticato e moderno ermetismo. Le Lezioni sulla Massoneria di Fichte sono inquadrate nel suo complesso pensiero filosofico e nella sua complicata esperienza di vita massonica. (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.

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)
