In «Mancanze, omissioni, e descrizioni negative»,55 Achille Varzi esplora le conseguenze di una forma comune di ragionamento causale, quella in cui citiamo mancanze od omissioni nel fornire una spiegazione delle cause degli eventi. Tale forma appare di comune uso nei contesti normativi del diritto, nelle spiegazioni tipiche delle scienze sociali e, più in generale, nel ragionamento ordinario. Ciò che accomuna questi casi è l’idea intuitiva secondo cui le cause possono anche consistere in eventi negativi. L’intuizione non è però metafisicamente innocua, (...) poiché per affermare che una spiegazione come "C’è stata un’esplosione perché Gianni non ha spento il gas" sia una buona spiegazione, occorre assumere che gli eventi negativi come “il non aver spento il gas da parte di Gianni” esistano al pari di eventi come l’esplosione e dal momento che, solo se sono entrambi eventi, può tra questi sussistere una relazione casuale. Dovremmo pertanto concludere che (1) è perfettamente intellegibile e rispecchia le nostre pratiche linguistiche. Spesso parliamo assumendo che ci siano cose che le persone non fanno: il gas che Gianni non ha spento, la passeggiata che non abbiamo fatto, il treno che non è arrivato, ecc. La sensatezza di questi usi esige pertanto il dover riconoscere una certa legittimità al vocabolario delle omissioni e delle descrizioni negative. Varzi sostiene che questo modo di parlare solleva tuttavia degli scrupoli ontologici,56 poiché non è possibile assumersi alcun serio impegno ontologico nei confronti di eventi negativi, ancor meno quando le nostre asserzioni richiedono di quantificare su eventi “inesistenti”. Una strategia per ovviare a questo scrupolo è sostenere che queste pratiche linguistiche sono analoghe a quelle in cui parliamo di oggetti “inesistenti”, ossia di oggetti che è come se ci fossero, ma che riconosciamo esistere soltanto in un contesto finzionale. Dunque l’analogia con gli oggetti finzionali può rendere in qualche modo espliciti i vincoli ontologici, giustificando quegli usi linguistici. Sebbene questo argomento abbia la sua plausibilità, Varzi nota che «ad un esame più attento, gli eventi non accaduti si rivelano ben più resistenti al rasoio di Occam di quanto l’analogia con gli oggetti non esistenti suggerisca » poiché il nostro linguaggio causale ci induce spesso a ritenere che «il riferimento o la quantificazione nei confronti di eventi non accaduti sia da intendersi in senso stretto e letterale»,57 in contrasto con quanto suggerisce l’analogia con gli oggetti finzionali. La difficoltà nasce dall’argomento per cui, se la causazione è una relazione tra eventi, occorre prendere sul serio l’idea che gli eventi negativi siano negativi stricto sensu. La tesi di Varzi è che questa tesi sia una contraddizione genuina e che l’unico modo di risolverla sia di rinunciare all’idea che gli eventi negativi esistano in un qualsiasi senso. In questo articolo intendo analizzare un aspetto di questa forma di parsimonia ontologica. Il mio intento è di valutare le conseguenze della tesi di Varzi dal punto di vista della spiegazione causale in contesti controfattuali e nei casi di omissione del diritto. (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, DanieleSantoro 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.

My paper provides reasons in support of the view that vague identity claims originate from a conflict between rigidity and precision in designation. To put this stricly, let x be the referent of the referential terms P and Q. Then, that the proposition “that any x being both a P and a Q” is vague involves that the semantic intuitions at work in P and Q reveal a conflict between P and Q being simultaneously rigid and precise designators. After having (...) shortly commented on an example of vague identity claim, I make the case for my proposal, by discussing how reference by baptism conflicts with descriptive attitudes towards understanding conceptual contents.

My paper characterizes religious beliefs in terms of vagueness. I introduce my topic by providing a general overview of my main claims. In the subsequent section, I develop basic distinctions and terminology for handling the notion of religious tradition and capturing vagueness. In the following sections, I make the case for my claim that religious beliefs are vague by developing a general argument from the interconnection between the referential opacity of religious belief content and the long-term communitarian history of the (...) precisification of what such content means. I start from describing an empirical example in the third section, and then I move to settle the matter in a conceptually argumentative frame in the fourth one. My conclusions in the final section address a few of consequences relevant to debates about religious epistemology and religious diversity. (shrink)
The paper proposes two logical analyses of (the norms of) justification. In a first, realist-minded case, truth is logically independent from justification and leads to a pragmatic logic LP including two epistemic and pragmatic operators, namely, assertion and hypothesis. In a second, antirealist-minded case, truth is not logically independent from justification and results in two logical systems of information and justification: AR4 and AR4¢, respectively, provided with a question-answer semantics. The latter proposes many more epistemic agents, each corresponding to a (...) wide variety of epistemic norms. After comparing the different norms of justification involved in these logical systems, two hexagons expressing Aristotelian relations of opposition will be gathered in order to clarify how (a fragment of) pragmatic formulas can be interpreted in a fuzzy-based question-answer semantics.

The problem of merging several ontologies has important applications in the Semantic Web, medical ontology engineering and other domains where information from several distinct sources needs to be integrated in a coherent manner.We propose to view ontology merging as a problem of social choice, i.e. as a problem of aggregating the input of a set of individuals into an adequate collective decision. That is, we propose to view ontology merging as ontology aggregation. As a first step in this direction, we (...) formulate several desirable properties for ontology aggregators, we identify the incompatibility of some of these properties, and we define and analyse several simple aggregation procedures. Our approach is closely related to work in judgment aggregation, but with the crucial difference that we adopt an open world assumption, by distinguishing between facts not included in an agent’s ontology and facts explicitly negated in an agent’s ontology. (shrink)
In this paper, I investigate the relationship between preference and judgment aggregation, using the notion of ranking judgment introduced in List and Pettit. Ranking judgments were introduced in order to state the logical connections between the impossibility theorem of aggregating sets of judgments and Arrow’s theorem. I present a proof of the theorem concerning ranking judgments as a corollary of Arrow’s theorem, extending the translation between preferences and judgments defined in List and Pettit to the conditions on the aggregation procedure.
We argue that a cognitive semantics has to take into account the possibly partial information that a cognitive agent has of the world. After discussing Gärdenfors's view of objects in conceptual spaces, we offer a number of viable treatments of partiality of information and we formalize them by means of alternative predicative logics. Our analysis shows that understanding the nature of simple predicative sentences is crucial for a cognitive semantics.
Relevant logics provide an alternative to classical implication that is capable of accounting for the relationship between the antecedent and the consequence of a valid implication. Relevant implication is usually explained in terms of information required to assess a proposition. By doing so, relevant implication introduces a number of cognitively relevant aspects in the de nition of logical operators. In this paper, we aim to take a closer look at the cognitive feature of relevant implication. For this purpose, we develop (...) a cognitively-oriented interpretation of the semantics of relevant logics. In particular, we provide an interpretation of Routley-Meyer semantics in terms of conceptual spaces and we show that it meets the constraints of the algebraic semantics of relevant logic. (shrink)
The impossibility results in judgement aggregation show a clash between fair aggregation procedures and rational collective outcomes. In this paper, we are interested in analysing the notion of rational outcome by proposing a proof-theoretical understanding of collective rationality. In particular, we use the analysis of proofs and inferences provided by linear logic in order to define a fine-grained notion of group reasoning that allows for studying collective rationality with respect to a number of logics. We analyse the well-known paradoxes in (...) judgement aggregation and we pinpoint the reasoning steps that trigger the inconsistencies. Moreover, we extend the map of possibility and impossibility results in judgement aggregation by discussing the case of substructural logics. In particular, we show that there exist fragments of linear logic for which general possibility results can be obtained. (shrink)
We study a fragment of Intuitionistic Linear Logic combined with non-normal modal operators. Focusing on the minimal modal logic, we provide a Gentzen-style sequent calculus as well as a semantics in terms of Kripke resource models. We show that the proof theory is sound and complete with respect to the class of minimal Kripke resource models. We also show that the sequent calculus allows cut elimination. We put the logical framework to use by instantiating it as a logic of agency. (...) In particular, we apply it to reason about the resource-sensitive use of artefacts. (shrink)
My paper argues for the claim that religious experience may provide evidential reasons in support of religious beliefs. I name such a claim epistemic view of mystical experience (EM). In the first section, I sketch two approaches to EM. Swinburne, Alston and Plantinga (among others) develop a notable defense of EM. On the contrary, seminal works by Feuerbach and Bultmann offer the opposite account. I briefly show how to resist to the criticism of EM. In light of such line of (...) reasoning, I move to Alston's Theory of Doxastic Practices (TDP) in the second section. After giving a skeletal account of TDP, I construe an argument in Alstonian terms against the naturalist refutations of EM. In the third section, I highlight the main problem with TDP, that is, the claim that perceptions and religious experiences have an analogical relation. Examples from sacred texts of different traditions show that such a claim fails to grasp what a religious experience is. In the final section I give a preliminary account of the notion of presentational experience, and show that it is possible to defend EM more plausibly than TDP does by the use of this notion.

An overview of the recent debate on the Trinity in the analytic philosophy of religion. I move from putting forward the Logical Problem of the Trinity (LPT) according to R.Cartwright and M.Rea. I then define two useful notions in order to evaluate the interpretive force of the mainstream approaches to answer LPT; i.e. , be X a concept, I define maximally robust reading of X and sufficiently robust reading of X. In the subsequent section, I offer an expository analysis of (...) Latin Trinitarianism, Social Trinitarianism and Material Constitution Trinitarianism in line with such concepts. I finally advance some reasons why neither of these properly work. My main argument is that every traditional phrasing of the doctrine of the Trinity asks Christians to hold maximally robust reading both of the onefoldness of God and the threefoldness of Divine Persons. Now, while Latin Trinitarianism, Social Trinitarianism and Material Constitution Trinitarianism provide maximally robust account of God's onefoldness, they can't give a maximally robust account for Persons' threefoldness.

We show how to embed a framework for multilateral negotiation, in which a group of agents implement a sequence of deals concerning the exchange of a number of resources, into linear logic. In this model, multisets of goods, allocations of resources, preferences of agents, and deals are all modelled as formulas of linear logic. Whether or not a proposed deal is rational, given the preferences of the agents concerned, reduces to a question of provability, as does the question of whether (...) there exists a sequence of deals leading to an allocation with certain desirable properties, such as maximising social welfare. Thus, linear logic provides a formal basis for modelling convergence properties in distributed resource allocation. (shrink)
In this paper, I discuss the analysis of logic in the pragmatic approach recently proposed by Brandom. I consider different consequence relations, formalized by classical, intuitionistic and linear logic, and I will argue that the formal theory developed by Brandom, even if provides powerful foundational insights on the relationship between logic and discursive practices, cannot account for important reasoning patterns represented by non-monotonic or resource-sensitive inferences. Then, I will present an incompatibility semantics in the framework of linear logic which allow (...) to refine Brandom’s concept of defeasible inference and to account for those non-monotonic and relevant inferences that are expressible in linear logic. Moreover, I will suggest an interpretation of discursive practices based on an abstract notion of agreement on what counts as a reason which is deeply connected with linear logic semantics. (shrink)
We show that linear logic can serve as an expressive framework in which to model a rich variety of combinatorial auction mechanisms. Due to its resource-sensitive nature, linear logic can easily represent bids in combinatorial auctions in which goods may be sold in multiple units, and we show how it naturally generalises several bidding languages familiar from the literature. Moreover, the winner determination problem, i.e., the problem of computing an allocation of goods to bidders producing a certain amount of revenue (...) for the auctioneer, can be modelled as the problem of finding a proof for a particular linear logic sequent.

Most literature on religious beliefs and disagreements among traditions focuses on a bit of mainstream assumptions: religions should be construed in substantive terms; religions are to be individuated by their core belief systems; adherents to a single tradition assent to the same belief system; religious beliefs have factual content; incompatible religious beliefs cannot be both true; and so on. In my work I question all these claims in order to defend a non kantian approach to deep pluralism. In the first (...) part I develop a narrative theory of doxastic practices. My fundamental intuition is that ambiguity, vagueness, and indeterminacy of meaning are non amendable features of any ordinary belief. Consequently, no proposition has a definite meaning, and there is no a priori reason to assume that if two believers assume the same belief, they both hold the same content. What I'm trying to do is to argue in support of a realist epistemology, without assuming a normative and rationalist stance. My evidential body is mainly drawn from psychology and psychoanalysis. In the second part I apply such a narrative theory to the study of the doxastic character of religions. I reject both functionalist and substantive approaches to religion, and I defend my own viewpoint which I label experentialism. After providing a characterization of religious beliefs, I refute how Alston, Ward and Hick account for the the doxastic features of religions. I then propose a definition of religious diversity which turns out to be alternative to the mainstream one. I work by empirical evidence from semiotics, sociology of religion and history of religions. In the third and conclusive part of my book, I give reasons against the mainstream approach to religious diversity, and I explain how my definition can be more appropriate to the sociological study of religious beliefs than the mainstream one. Finally, I provide an account of deep pluralism, I show that my approach to religious epistemology and religions is compatible with (and recommended by) deep pluralism, I differentiate kantian from non kantian pluralism, and I explain why non kantian deep pluralism resists the traditional objections to pluralism. Throughout the book I discuss relevant materials from Hinduism, Judaism, Christianity, and Islam. (shrink)
In this article we present an advanced version of Dual-PECCS, a cognitively-inspired knowledge representation and reasoning system aimed at extending the capabilities of artificial systems in conceptual categorization tasks. It combines different sorts of common-sense categorization (prototypical and exemplars-based categorization) with standard monotonic categorization procedures. These different types of inferential procedures are reconciled according to the tenets coming from the dual process theory of reasoning. On the other hand, from a representational perspective, the system relies on the hypothesis of conceptual (...) structures represented as heterogeneous proxytypes. Dual-PECCS has been experimentally assessed in a task of conceptual categorization where a target concept illustrated by a simple common-sense linguistic description had to be identified by resorting to a mix of categorization strategies, and its output has been compared to human responses. The obtained results suggest that our approach can be beneficial to improve the representational and reasoning conceptual capabilities of standard cognitive artificial systems, and –in addition– that it may be plausibly applied to different general computational models of cognition. The current version of the system, in fact, extends our previous work, in that Dual-PECCS is now integrated and tested into two cognitive architectures, ACT-R and CLARION, implementing different assumptions on the underlying invariant structures governing human cognition. Such integration allowed us to extend our previous evaluation. (shrink)
Among the possible solutions to the paradoxes of collective preferences, single-peakedness is significant because it has been associated to a suggestive conceptual interpretation: a single-peaked preference profile entails that, although individuals may disagree on which option is the best, they conceptualize the choice along a shared unique dimension, i.e. they agree on the rationale of the collective decision. In this article, we discuss the relationship between the structural property of singlepeakedness and its suggested interpretation as uni-dimensionality of a social choice. (...) In particular, we offer a formalization of the relationship between single-peakedness and its conceptual counterpart, we discuss their logical relations, and we question whether single-peakedness provides a rationale for collective choices.

My paper challenges the externalist mainstream assumptions towards the understanding of religious beliefs (i.e., reliabilism by W.Alston, the warrant belief approach by A.Plantinga, the neowittgensteinian analysis of doxastic systems). According to such assumptions, religious beliefs should be evaluated rational in terms of the same doxastic standard giving justification for ordinary factual beliefs. Moving from the empiricist intuition that the kind of content of belief matters to the form of belief and the justification practices for it, I argue for the claim (...) that religious beliefs do not concern facts or experiences but assiological interpretations of facts or experiences. After some brief introductory considerations, in the second section of my paper I provide criteria for distinguishing between factual and non factual beliefs, and I offer a general account for the doxastic spectrum. In the subsequent section I characterize the assumption of religious beliefs as qualitative, mostly implicit and in the de dicto modality. In order to prove my characterization I draw a phenomenology of religious belief from individual testimonies concerning religious conversion. I finally conclude answering some objections in the fourth section of the paper. (shrink)
Following the speech act theory, we take hypotheses and assertions as linguistic acts with different illocutionary forces. We assume that a hypothesis is justified if there is at least a scintilla of evidence for the truth of its propositional content, while an assertion is justified when there is conclusive evidence that its propositional content is true. Here we extend the logical treatment for assertions given by Dalla Pozza and Garola by outlining a pragmatic logic for assertions and hypotheses. On the (...) basis of this extension we analyse the standard logical opposition relations for assertions and hypotheses. We formulate a pragmatic square of oppositions for assertions and a hexagon of oppositions for hypotheses. Finally, we give a mixed hexagon of oppositions to point out the opposition relations for assertions and hypotheses. (shrink)
In this paper I develop an account of petitio principii (the fallacy sometimes also called ‘vicious circularity’, or ‘begging the question’) which has two crucial features: it employs the notion of doxastic justification, and it takes circularity to be relative to an evidential state. According to my account, an argument will be circular relative to an evidential state if and only if having doxastic justification for the conclusion is necessary, for a subject in that evidential state, to have doxastic justification (...) for the premisses. I compare the account to some existing ones, and claim some advantages. I then rebut an objection which threatens to undermine the importance of one of those advantages. This account seems to shed new light on the old problem of characterizing petitio principii. It avoids the two obvious problems which any account of this phenomenon must face: being too narrow, for example by leaving out all arguments in which the conclusion does not appear among the premisses, and being too wide, making all valid arguments circular.

My paper moves from Kant's taxonomy for the arguments for the existence of God. After providing a brief survey of Kant's account, I claim that contemporary arguments from design fit Kant's characterization of the physico-theological argument. Then, in the second section, I deal with the logical frame of the argument from design. In the third section I introduce Berkeley's divine language argument (DLA), in order to demonstrate that DLA is an argument from design. Consequently, in the fourth section, I give (...) a refutation of Hooker's and Kline's reading of DLA. Finally, in the last section, I take Berkeley's DLA as a paradigmatic case of the argument from design, showing a fundamental difficulty the argument endorses. (shrink)
We overview the main historical and technological elements characterising the rise, the fall and the recent renaissance of the cognitive approaches to Artificial Intelligence and provide some insights and suggestions about the future directions and challenges that, in our opinion, this discipline needs to face in the next years.
Public deliberation has been defended as a rational and noncoercive way to overcome paradoxical results from democratic voting, by promoting consensus on the available alternatives on the political agenda. Some critics have argued that full consensus is too demanding and inimical to pluralism and have pointed out that single-peakedness, a much less stringent condition, is sufficient to overcome voting paradoxes. According to these accounts, deliberation can induce single-peakedness through the creation of a ‘meta-agreement’, that is, agreement on the dimension according (...) to which the issues at stake are ‘conceptualized’. We argue here that once all the conditions needed for deliberation to bring about single-peakedness through meta-agreement are unpacked and made explicit, meta-agreement turns out to be a highly demanding condition, and one that is very inhospitable to pluralism.

We show that logic has more to offer to ontologists than standard first order and modal operators. We first describe some operators of linear logic which we believe are particularly suitable for ontological modeling, and suggest how to interpret them within an ontological framework. After showing how they can coexist with those of classical logic, we analyze three notions of artifact from the literature to conclude that these linear operators allow for reducing the ontological commitment needed for their formalization, and (...) even simplify their logical formulation. (shrink)
We reconsider the pragmatic interpretation of intuitionistic logic [21] regarded as a logic of assertions and their justi cations and its relations with classical logic. We recall an extension of this approach to a logic dealing with assertions and obligations, related by a notion of causal implication [14, 45]. We focus on the extension to co-intuitionistic logic, seen as a logic of hypotheses [8, 9, 13] and on polarized bi-intuitionistic logic as a logic of assertions and conjectures: looking at the (...) S4 modal translation, we give a de nition of a system AHL of bi-intuitionistic logic that correctly represents the duality between intuitionistic and co-intuitionistic logic, correcting a mistake in previous work [7, 10]. A computational interpretation of cointuitionism as a distributed calculus of coroutines is then used to give an operational interpretation of subtraction.Work on linear co-intuitionism is then recalled, a linear calculus of co-intuitionistic coroutines is de ned and a probabilistic interpretation of linear co-intuitionism is given as in [9]. Also we remark that by extending the language of intuitionistic logic we can express the notion of expectation, an assertion that in all situations the truth of p is possible and that in a logic of expectations the law of double negation holds. Similarly, extending co-intuitionistic logic, we can express the notion of conjecture that p, de ned as a hypothesis that in some situation the truth of p is epistemically necessary. (shrink)
My paper provides a preliminary work towards a theory of freedom and agency which I name "Theory of Procedural Agency (TPA)". Since TPA relies on intuitions which can not be settled into the metaphysical framework of contemporary approaches to freedom and agency, I focus on some reasons which explain why these intuitions should be preferred to the competing ones. My strategy is to argue for my view defending an embryonal version of TPA, that is Berkeley's considerations on free will, agency (...) and determinism. In the first section I deal with Berkeley's treatment of free will. My idea is that his arguments offer clear and evident reasons in support of the first intuition grounding a TPA like approach to freedom. In the second section I move some criticisms to Berkeley's theory of will, claiming that, in order to overcome these, the assumption of the constitution view concerning self-knowledge would help. In the third section I set forth a logical formulation for TPA, showing how Berkeley's consideration on agency provide grounding reasons for that. Finally, in the last section, I plan the work to be done to achieve a consistent and complete version of TPA. (shrink)
Persistent disagreements may induce parties in the disagreement to experience a strong state of anxiety. Such anxiety has a psychological nature in ordinary cases of disagreement (i.e., cases which do not impact on the doxastic identity of the opposing epistemic agents). On the contrary, the more the content of a disagreement concerns basic issues related to the non-negotiable views for the parties involved, the more anxiety turns out to be of an epistemic kind, and, accordingly, suggests a set of normative (...) consequences. I will outline the main differences between ordinary and doxastic-identity-related disagreements in terms of the nature of the anxiety they give rise. In light of this distinction, I will characterize religious disagreements as disagreements of the latter type, and I will provide a few insights for approaching them. (shrink)
The theorizing about the doctrine of the Trinity by contemporary analytic philosophers of religion has recently been imbued with an air of enthusiastic excitement and self-confidence. My intuition is that there’s room for saying something more in support to the embarrassment and puzzlement traditionally related to the predication of God’s onefoldness and threefoldness. My purpose is to deliver a general argument for (weak) trinitarian skepticism. My view is that the argument provides substantive reasons in support to the common sense intuition (...) that either God’s onefoldness and threefoldness aren’t actually compatible or God’s onefoldness and threefoldness aren’t robustly construed.

David Berman's work on experimental philosophy is a defence of a traditional approach to empiricism against both contemporary rationalism and logico-analytic philosophy. While his approach focuses on empirical evidence in support of theoretical claims, Berman distinguishes his position from the kind of experimentalism recently risen from the analytic world. After having highlighted the merit of Berman's approach to philosophy, I comment on his main views, addressing particularly the relationship between language, intuitions and experience from the standpoint of the epistemological topic (...) of belief justification. (shrink)
My main claim is that, in order to account for the nature of human mind, philosophy of mind should embody topics usually treated by disciplines as ethics or applied philosophy so as to enrich the pure notion of cognitive experience to the extent of treating the whole of human experience. I begin with considering the Cartesian approach to the "cogito". I argue for the claim that cartesian-like dualists (Descartes and Locke, Kant and Husserl) fail in treating the opposition of internalism (...) and externalism concerning experience. This failure commits them to a form of epistemological idealism unable to manage the "veil of perception" objection. I then settle a provisional account for the mind, mainly dependent on a Berkeleyan-Humean deflationist approach to it, showing the necessity to incorporate in it robust practical topics from an ontological point of view.

George Berkeley (1685-1753) is one of the most influential early modern philosophers, and in reason of this a never-ending critical interest focuses on his works. Such a critical attention gave rise to a broad literature and it is in fact quite easy to find valuable introductory books to Berkeley's works. It would be thus superfluous to provide a further summary of the entire production of Berkeley. Rather, I focus on a specific issue, namely the main points of interest of immaterialism (...) for the contemporary debates in philosophy. The currently most discussed Berkeleian arguments are those from his earlier production (those developed around 1709-1713). Thus, I will be mainly concerned with the conceptual structure of A Treatise Concerning the Principles of Human Knowledge. Among Berkeley's early works, this is the one that was thought as a systematic illustration for philosophers of his ideas. (shrink)
My paper addresses the notion of moral responsibility in religious ethics. I begin with the outline of the doctrine of moral heteronomy. The scripture stories of the Tables of the Laws and the Holy Covenant provide the general pattern for heteronomic ethics. My claim is that heteronomic ethics transfers the responsibility for the action A an agent x is performing from x to the normative system commanding x to perform A. I then picture the architecture of the normative system of (...) the Decalogue (System D) and I work out criteria for the completeness and consistency of the system. In the next section I make the case for the actual incompleteness and inconsistency of D. As a consequence, an agent subject to the authority of D can not rule his moral conduct by the norms in D. Therefore, the acceptance of D transfers the moral responsibility for the actions by x from x to D, but D does not provide a complete and consistent system of norms to rule x's conduct. In the final section of the paper I briefly present the way religious ethics deals with this problem, by offering an alternative approach to the notion of moral responsibility. (shrink)
My paper addresses what a religion is. I comment briefly on the "substantive versus functionalist" debate, and I provide reasons to reject both of them. While I offer short summary arguments against the functionalist approach, I develop two detailed arguments against the substantive one. The former moves from the evidence that religious beliefs change over time. The latter moves from internal disagreements about the meaning of the core beliefs of a faith. These two arguments show that it is impossible to (...) reduce the belief system of any historical faith to a set of propositions which all the adherents to a tradition assent to. Although my arguments are conceptual, I include also empirical materials in support of my view. I then conclude by presenting a pluralist account of religions from an internalist standpoint. (shrink)
Evolutionary research on the biological fitness of groups has recently given a prominent value to the role that prosocial behaviors play in favoring a successful adaptation to ecological niches. Such a focus marks a paradigm shift. Early views of evolution relied on the notion of natural selection as a largely competitive mechanism for the achievement of the highest amount of resources. Today, evolutionists from different schools think that collaborative attitudes are an irremovable ingredient of biological change over time. As a (...) consequence, a number of researchers have been attracted by evolutionary studies of human behaviors. Some think that a continuity among prosocial attitudes of human beings and other social mammals can be detected, and that this fact has relevance for accounting for human morality. Others deny one or the other of these claims, or both. The papers in the present special issue address how these topics impact ethics and religion. (shrink)
An introduction to how heteronomous views address the topic of moral autonomy. In the first section I provide a short history of the rise of the autonomy stance in meta ethics. Then I sketch the relationship between Kant and mainstream contemporary Kantians. I finally outline a summary of the papers in the special issue of Dialegesthai.
The paper is divided in two parts. The first presents my exegesis of the fourth chapter of the Gospel of John. My main claim is that the composer of the text manipulate the chronological order of miracles in his "signs source" in order to approach the story of the woman from Samaria together to the healing of the son of the roman officer in Kapharnaus. The two episodes deal with two different ways to convert to faith. Consequently, they provide a (...) complete phenomenology of the formation process of religious belief. The second part considers two fundamental interpretations of the johannine notion of faith, i.e. the fideistical and the existentialist. I reject both: the first is logically inconsistent within the Johannine framework (the Gospel of John assumes principles whose consequences contradict the fideistic interpretation of faith); the second is ontologically senseless. (shrink)
The critical target of my paper is the normativist stance of Kantian meta ethics. After a very short introduction, I develop a characterization of contemporary mainstream Kantism as a conjunction of a normativist claim, a rationalist claim and a proceduralist claim. In the subsequent section I make the case against the normativist claim by drawing a counterexample, and defend the relevance of such counterexample as a reason that defeats the appeal of the Kantian approach to meta ethics. I finally conclude (...) by highlighting the main reasons why the challenge my counterexample rises are not answerable within a Kantian framework. (shrink)
My starting assumption concerns the default view in western aestethics. My claim is that the view can be characterized in the following manner: while the arts and religious experience are formally different kinds of human experience, the arts have the same content of religious experience (Essentialist claim, EC). I argue that both from a realist and antirealist standpoint EC does not make sense. Consequently, EC should be rejected as the right approach to the relation between the arts and religious experience.
I consider an argument by Plotinus to show how the notion of transcendence is used in explaining the nature of knowledge. The argument is set forth in sections 4-6 of the treatise V.8 (31). In my opinion this argument provides a good example of the philosophical frame of Platonism. I sum up this frame in the following theses: a) for a thing being is to be real and true; so that for a thing being real and being true is equivalent; (...) but b) for a thing being real and true means being intelligible; that is to say: a thing could be understood because that thing is a being; thus, c) for a thing being is the identity of its ontological and epistemological nature.

This thesis discusses some central aspects of Wittgenstein's conception of language and logic in his Tractatus Logico-Philosophicus and brings them into relation with the philosophies of Frege and Russell. The main contention is that a fruitful way of understanding the Tractatus is to see it as responding to tensions in Frege's conception of logic and Russell's theory of judgement. In the thesis the philosophy of the Tractatus is presented as developing from these two strands of criticism and thus as the (...) culmination of the philosophy of logic and language developed in the early analytic period. Part one examines relevant features of Frege's philosophy of logic. Besides shedding light on Frege's philosophy in its own right, it aims at preparing the ground for a discussion of those aspects of the Tractatus' conception of logic which derive from Wittgenstein's critical response to Frege. Part two first presents Russell's early view on truth and judgement, before considering several variants of the multiple relation theory of judgement, devised in opposition to it. Part three discusses the development of Wittgenstein's conception of language and logic, beginning with Wittgenstein's criticism of the multiple relation theory and his early theory of sense, seen as containing the seeds of the picture theory of propositions presented in the Tractatus. I then consider the relation between Wittgenstein's pictorial conception of language and his conception of logic, arguing that Wittgenstein's understanding of sense in terms of bipolarity grounds his view of logical complexity and of the essence of logic as a whole. This view, I show, is free from the internal tensions that affect Frege's understanding of the nature of logic. (shrink)
This paper investigates Wittgenstein’s account of the relation between elementary and molecular propositions (and thus, also, the propositions of logic) in the Tractatus Logico-Philosophicus. I start by sketching a natural reading of that relation – which I call the “bipartite reading” – holding that the Tractatus gives an account of elementary propositions, based on the so-called picture theory, and a different account of molecular ones, based on the principle of truth- functionality. I then show that such a reading cannot be (...) attributed to Wittgenstein, because he holds the view that an explanation of logical complexity is already given by a correct account of the (pictorial) nature of elementary propositions; this is implied in his claim that “an elementary proposition contains all logical constants/operations in itself”. After clarifying Wittgenstein’s notion of an operation from the Notes on Logic to the Tractatus, I finally explain why Wittgenstein claims that an elementary proposition contains all logical operations in itself, and hence why he can be said to provide a unified (and thus not bipartite) account of language and logic.

According to a recent philosophical claim, “works of fiction are thought experiments” (Elgin 2007: 47), though there are relevant differences, as the role of spoilers shows—they can ruin a novel but improve the understanding we can gain through a thought experiment. In the present article I will analyze the role of spoilers and argue for a more differentiated perspective on the relation between literature and thought experiments. I will start with a short discussion of different perspectives on thought experiments and (...) argue that the mental-model view and the conception of games of make-believe are most promising for developing the present analogy. Then I will assess the similarities and differences between thought experiments and other works of fiction. I will focus on the role of spoilers and, more generally, on the foretaste context, of which they are part. This context guides readers of literary works of art to draw their attention to the literary and aesthetic quality of the text. In the case of thought experiments, on the other hand, it (i) prompts them to accept the presence of fictional elements in worldly-cognitive works and (ii) draws their attention towards cognitively relevant elements of the story. A discussion of Borges’ Pierre Menard in the last part will show that literary works of art become thought experiments if they are embedded in an appropriate foretaste context. Spoilers, thus, unveil that even works which—due to their length or plenty of detail—usually are not considered thought experiments, can perform similar cognitive functions. (shrink)
We present a number of modal logics to reason about group norms. As a preliminary step, we discuss the ontological status of the group to which the norms are applied, by adapting the classification made by Christian List of collective attitudes into aggregated, common, and corporate attitudes. Accordingly, we shall introduce modality to capture aggregated, common, and corporate group norms. We investigate then the principles for reasoning about those types of modalities. Finally, we discuss the relationship between group norms and (...) types of collective responsibility. (shrink)
In recent years, there has been an increasing interest in thedevelopment of ontologically well-founded conceptual models for Information Systems in areas such as Service Management, Accounting Information Systems and Financial Reporting. Economic exchanges are central phenomena in these areas. For this reason, they occupy a prominent position in modelling frameworks such as the REA (Resource-EventAction) ISO Standard as well as the FIBO (Financial Industry BusinessOntology). In this paper, we begin a well-founded ontological analysisof economic exchanges inspired by a recent ontological (...) view on the nature of economic transactions. According to this view, what counts asan economic transaction is based on an agreement on the actions thatthe agents are committed to perform. The agreement is in turn based on convergent preferences about the course of action to bring about. This view enables a unified treatment of economic exchanges, regardless the object of the transaction, and complies with the view that all economictransactions are about services. In this paper, we start developing our analysis in the framework of the Unified Foundational Ontology (UFO). (shrink)
