Questo articolo divulgativo è stato pubblicato il 24 marzo 2021 sulla rivista l'Indiscreto. Le waifu sono personaggi di opere di finzione, per lo più anime, verso i quali molti giovani maschi provano una forta attrazione, fino all'ossessione. Perché delle opere di fantasia suscitano tali sentimenti, che sembrano presupporre il trattare gli eventi osservati come se fosser reali? Questo è il paradosso della fiction. In un certo senso, la teoria della controparte di D. K. Lewis potrebbe essere utilizzato per affermare che, (...) in effetti, i personaggi delle opere di finzione sono reali. Alla fine, però, rifiuto tale interpretazione, sostenendo, invece, che i personaggi di finzione sono versioni alternative di persone reali, e che i sentimenti che si provano sono rivolti a tali persone reali, o comunque a chi può aver realmente vissuto eventi analoghi.

This study is a phenomenological inquiry into several relatively unexplored phenomena, including certain key methodological issues. It seeks to elicit and explicate the grounds of free-fantasy variation, which Husserl insists contains his “fundamental methodological insight” since it articulates “the fundamental form of all particular transcendental methods…” In the course of pursuing the full sense of this method and its grounds, the essay also uncovers the origins and eventual presence of “self” and explores the multiple connections among self, mental life, embodiment (...) and the surrounding world. To that end, it is necessary to take seriously Husserl’s otherwise odd declaration that “‘feigning’ [‘Fiktion’] makes up the vital element of phenomenology as of every other eidetic science…”, and thus that every philosopher must “fertilize” his or her “fantasy” through works of art and history as well as other areas and practices of human life. The essay offers an in-depth probing of several striking but largely unexplored phenomena: exemplifying and possibilizing, and concludes with an exploration of one of the most pervasive themes in phenomenological inquiry: intersubjectivity.

ABSTRACT (ITA) Un’idea emerge, si sviluppa, guadagna consenso, muta, talvolta scompare per poi risorgere. Questo è anche stato il destino dell’idea di evoluzione, il cui lungo cammino viene ricostruito in questo saggio, dai Greci fino ai nostri giorni. A partire dal diciassettesimo secolo questa nozione assume sempre più rilevanza nello studio della natura. In ciascun pensatore l’idea di un’evoluzione delle specie viventi è stata accompagnata da una teoria volta a spiegare le cause e il meccanismo del mutamento. Questo saggio racconta (...) non soltanto la genesi e lo sviluppo dell’idea tout court che la natura in qualche modo si trasformi, ma anche la storia delle teorie che, assumendo come reale questa trasformazione, ne postulano una spiegazione. Particolare attenzione viene data ad alcuni aspetti spesso trascurati che hanno reso possibile il concetto di evoluzione del mondo vivente come la conosciamo adesso, di cui se ne mostra la rilevanza, già a partire dal pensiero greco. -/- ABSTRACT (ENG) An idea emerges, develops, gains consensus, evolves, sometimes disappears and then rises again. This was also the fate of the idea of evolution, whose long journey is reconstructed in this essay, from the Greeks to the present day. Since the seventeenth century, this idea has become more and more relevant in the study of nature. In each thinker the idea of an evolution of living species has been accompanied by a theory aimed at explaining the causes and the mechanism of change. This essay tells not only the genesis and development of the idea that nature somehow transforms itself, but also the history of the theories which, assuming this transformation as real, postulate an explanation. Particular emphasis is given to some often overlooked aspects that made possible the concept of evolution of the living world as we know it now, whose full relevance is shown, starting from Greek thought. Keywords: evolution, natural selection, Charles Darwin, history of ideas, history of science. (shrink)

The emerging crealectic frame posits that there are three complementary and effectual domains of intelligence, namely analytic, dialectic, and crealectic, being alternatively or complementarily used in human interactions with the world. The focus of crealectic intelligence is the relative possibilization and local realization of absolute possibility, the becoming real, biological, and social of creation. This multimodal externalization and asymptotic unification of a cosmological flux expresses itself via three realms of possibilization: physical, psychological, and philosophical. But the philosophical possible is not (...) merely abstract; it originates a generative process of exteriorizations, interiorizations, dissolutions, and unifications transforming the possible into realities. The term “crealectics,” coined by philosopher and author Luis de Miranda, is a compound of “Creal” and of two possible suffixes: “logos” or “ektos”. The ontological core of crealectics, the Creal, is the immanent process of creation understood as a ubiquitous stream of absolute possibility exteriorizing itself. For a crealectician, philosophy is not the mere logical analysis of truth conditions, but the self-questioning enterprise of thought regarding its own possibilizing and world-making power. (shrink)

ABSTRACT (ENG) The recent evolution of the most advanced societies is characterized by the increasing use of hypertext. The latter is an electronic text with hyperlinks to other text that a user can immediately access. The World Wide Web itself is a sort of global hypertext that can be viewed as a network of nodes, represented by individual elements connected through the so-called links. In this paper, I ask myself in what sense reading with new technologies is a different cognitive (...) experience from reading a printed text. In the first part, I examine the conditions that made the emergence of hypertext possible by examining some mutations in human thought. In the second part, I argue that the emergence of hypertext has not only made the reading experience different but has also reshaped the figure of the reader. -/- ABSTRACT (ITA) L’evoluzione recente delle società più avanzate è caratterizzata dall’uso crescente dell’ipertesto. Quest’ultimo è un testo elettronico con riferimenti ad altri documenti, accessibili cliccando su parole chiave. Lo stesso World Wide Web una sorta di ipertesto globale che si può immaginare come una rete di nodi, rappresentati da singoli elementi connessi attraverso i cosiddetti link. In questo articolo ci chiediamo in che senso leggere con le nuove tecnologie sia un’esperienza cognitiva differente rispetto a quella di leggere un testo stampato. Nella prima parte esaminiamo le condizioni che hanno reso possibile l’emergere dell’ipertesto considerando alcune mutazioni in seno al pensiero umano. Nella seconda parte argomentiamo che con l’ipertesto è nata una nuova forma di lettura che ha a sua volta costituito una nuova figura di lettore. (shrink)

La logica modale è nata per studiare i ragionamenti su ciò che è possibile e ciò che è necessario. Negli ultimi decenni, a partire dal lavoro di logici e filosofi quali Rudolf Carnap, Saul Kripke e David Lewis, la sua applicazione è stata progressivamente estesa ad altri ambiti, quali il ragionamento sul tempo, sulla conoscenza e sui sistemi di norme. Queste ricerche hanno condotto a un complesso e intrigante dialogo con alcune fondamentali branche della filosofia: la metafisica, l’epistemologia, la (...) filosofia del linguaggio. Lo scopo del volume è offrire una panoramica di questo dialogo al contempo accessibile e rigorosa, pensata sia per gli studenti di un corso universitario, sia per il lettore non specialista. Se da un lato tutte le necessarie nozioni tecniche sono rese accessibili ai non addetti ai lavori, dall'altro si restituisce un'immagine fedele delle sfide concettuali che la ricerca in questi settori è oggi chiamata ad affrontare.

Universal health coverage (UHC) is at the center of current efforts to strengthen health systems and improve the level and distribution of health and health services.

As such, the report is relevant for every actor that affects that path and governments in particular, as they are in (...) charge of overseeing and guiding the progress toward UHC. (shrink)

The modern Everett interpretation of quantum mechanics describes an emergent multiverse. The goal of this paper is to provide a perspicuous characterisation of how the multiverse emerges making use of a recent account of (weak) ontological emergence. This will be cashed out with a case study that identifies decoherence as the mechanism for emergence. The greater metaphysical clarity enables the rebuttal of critiques due to Baker (2007) and Dawid and Th\'ebault (2015) that cast the emergent multiverse ontology as incoherent; responses (...) are also offered to challenges to the Everettian approach from Maudlin (2010) and Monton (2013).

This paper is about a problem that can arise when we try to harness the “wisdom of the crowd” from groups comprised of individuals who exhibit a certain kind of epistemic humility in the way they respond to testimonial evidence. I begin by setting out the problem and then make some initial steps toward solving it. The solution I develop is tentative and may not apply in all circumstances, but it promises to alleviate what seems to me to be a (...) problem of both theoretical interest and practical importance.

Language is the main resource for meaningful action, including the very formation of selves and psychosocial identities, shaped by practical norms, beliefs, and values. Thus, language education constitutes one of the most powerful means for both social reproduction and social production and ideological maintenance and utopian innovation. In this paper, we attempt to emphasise the invaluable psychosocial, political, economic, and cultural function of language education in order to propose a critical view of the current transition from the monolingual to a (...) multilingual paradigm. We maintain that multilingual approaches tend to serve the neoliberal framework and reproduce its systemic inequalities. Therefore, we argue in favour of emancipatory multilingual practices that could embody a translingual pedagogy capable of promoting the development of capabilities, the recognition of otherness, and the cultivation of diversity. Rooted in critical theory, namely in Foucault’s notion of subjectification and Freire’s view of conscientisation, an emancipatory translingual pedagogy would enable and empower every learner to synthesise a contextually creative field of new semantic and pragmatic relationships. Critical language education would enhance the ethos of biophilia that fosters what we term the poetics of communality and selfhood, that is to say, the proactive commitment to expanding symbolic and existential novelty.

The aim of this essay is to review Friedrich Nietzsche's "The Gay Science" in English Translation. It compares and contrasts the translations by Thomas Common, Walter Kaufmann, Josefine Nauckhoff, and R. Kevin Hill. First, I argue in favor of translating the work's title "Die Fröhliche Wissenschaft" as "The Gay Science" or perhaps more precisely as "The Gay Knowledge". Nietzsche who is likely the greatest stylist in the German language wrote with philological precision and succinctness. This exactitude and awareness of the (...) shaping influence of linguistic means on the contents expressed therefore needs to be reflected throughout in any kind of rendition of Nietzsche's artful texts and the evaluation and assessment thereof.

In 2006 we awoke, in Europe at least, to the odd situation in which twitchers – obsessive birdwatchers who spend much of their leisure time on the far-flung edges of countries – are being reinvented as the eyes and ears of the state, helping warn of new border incursions. These incursions are posited as taking an avian form that may bring with it very unwelcome pathogens. Everyday avian observations and knowledges of migratory routes are being reinvented as a kind of (...) border patrol, a first line of veterinary surveillance. (shrink)

There are at least three dimensions to rights. We may have and lack freedom to 1) be, 2) do, and 3) have. These dimensions reformulate Locke’s categories, and are further complicated by placing them within the context of domains such as natural or civil rights. Here the question of the origins of rights is not addressed, but issues concerning how we may contextualize them are discussed. Within the framework developed, this paper makes use of Actor-Network Theory and Enlightenment values to (...) examine the multidimensionality and appropriateness of animal rights and human rights for posthumans. The core position here is that rights may be universal and constant, but they can only be accessed within a matrix of relative cultural dimensions. This will be true for posthumans, and their rights will be relative to human rights and dependent on human and posthuman responsibilities. (shrink)

The story of Abraham – and the divine command to sacrifice his son Isaac – is, as many of us know, the source of inspiration for some reflections of Kierkegaard in his work Fear and Trembling. From this episode, Johannes de Silentio, the pseudony- mous author of the work, who makes an ode to faith as the highest of the passions, also wonders about a problem that, according to his interpretation, seems central, i.e. the teleological suspension of morality. The objective (...) of this paper is to investigate, especially from the reflections of Kierkegaard, a possible interpretation for the teleological suspension of morality and in what circumstances such a thing does occur and where we can insert it in the ethical debates of philosophy of the nineteenth century.

The resolution of the celebrated θ-τ enigma of elementary particle physics through the introduction of the parity violation law by T.D. Lee and C.N. Yang in 1956, may be epistemologically considered as a possible historical instance mostly explainable by means of that particular aspect of Kuhnian theory of scientific revolutions invoking the Gestalt switches as possible psychological patterns whose paradigm’s change is puts into analogy with those inherent the natural sciences (paradigm switches). From what said, then, it will be possible (...) to outline further elementary epistemological considerations. (shrink)

Firstly, the "Metaverse" possesses two distinctive features, "thickness" and "imagination," promising the public a structure of unknown scenarios but with unclear definitions. Attempts to establish an open framework through incompleteness, however, fail to facilitate interactions between humans and the scenario. Due to the dilemma of "digital twinning," the "Metaverse" cannot be realized as "another universe". Hence, the "Metaverse" is, in fact, only a virtual experiential territory created by aggregating technologies that offer immersion and interactivity. Secondly, when artificial intelligence serves as (...) a key supporting technology for the "Metaverse," it presents multifaceted existential risks, manifested as safety, cognitive, and ethical dilemmas. Finally, we propose that the framework for responsible "Metaverse" governance should be constructed through three pathways: collective responsibility, realism, and the co-governance of the virtual and real.

Per la prima volta in duemila anni di pedagogia stiamo parlando di didattica digitale. L’evento epocale che ha determinato questo suo improvviso irrompere nelle vite delle famiglie è stata, com’è noto, l’emergenza Covid19.

Impossible worlds are representations of impossible things and impossible happenings. They earn their keep in a semantic or metaphysical theory if they do the right theoretical work for us. As it happens, a worlds-based account provides the best philosophical story about semantic content, knowledge and belief states, cognitive significance and cognitive information, and informative deductive reasoning. A worlds-based story may also provide the best semantics for counterfactuals. But to function well, all these accounts need use of impossible (...) and as well as possible worlds. So what are impossible worlds? Graham Priest claims that any of the usual stories about possible worlds can be told about impossible worlds, too. But far from it. I'll argue that impossible worlds cannot be genuine worlds, of the kind proposed by Lewis, McDaniel or Yagisawa. Nor can they be ersatz worlds on the model proposed by Melia or Sider. Constructing impossible worlds, it turns out, requires novel metaphysical resources. (shrink)

Truthmaker says that things, broadly construed, are the ontological grounds of truth and, therefore, that things make truths true. Recently, there have been a number of arguments purporting to show that if one embraces Truthmaker, then one ought to embrace Truthmaker Maximalism—the view that all non-analytic propositions have truthmakers. But then if one embraces Truthmaker, one ought to think that negative existentials have truthmakers. I argue that this is false. I begin by arguing that recent attempts by Ross Cameron and (...) Jonathan Schaffer to provide negative existentials with truthmakers fail. I then argue that the conditional—if one embraces Truthmaker, the one ought to embrace Truthmaker Maximalism—is false by considering worlds where very little, if anything at all, exists. The conclusion is that thinking that negative existentials do not have truthmakers, and therefore rejecting Truthmaker Maximalism, need not worry Truthmaker embracers. (shrink)

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.

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.

l argue that, contra Chalmers,a skeptical scenario involving deception is a genuine possibility,even if he is correct that simulations are real. I call this new skeptical position “Illusory World Skepticism.” Illusory World Skepticism draws from the simulation argument,together with work in physics,astrobiology, and AI,to argue that we may indeed be in an illusory world—a universe scale simulation orchestrated by a deceptive AI—the technophilosopher’s ultimate evil demon. In Section One I urge that Illusory World Skepticism is a bone fide skeptical possibility. (...) In Section Two, I explore features of quantum computation. Then, in Sections Three and Four, I draw from the discussion of quantum computation and assume that the simulation argument is correct,applying considerations from the fields of astrobiology and AI safety to illustrate that illusory world skepticism constitutes what I call “a serious epistemic threat”, a scenario that cannot be dismissed as requiring that knowledge is certainty or which seems to just depict a remote, fictional situation.

In this paper, I investigate whether we can use a world-involving framework to model the epistemic states of non-ideal agents. The standard possible-world framework falters in this respect because of a commitment to logical omniscience. A familiar attempt to overcome this problem centers around the use of impossible worlds where the truths of logic can be false. As we shall see, if we admit impossible worlds where “anything goes” in modal space, it is easy to model extremely non-ideal (...) agents that are incapable of performing even the most elementary logical deductions. A much harder, and considerably less investigated challenge is to ensure that the resulting modal space can also be used to model moderately ideal agents that are not logically omniscient but nevertheless logically competent. Intuitively, while such agents may fail to rule out subtly impossible worlds that verify complex logical falsehoods, they are nevertheless able to rule out blatantly impossible worlds that verify obvious logical falsehoods. To model moderately ideal agents, I argue, the job is to construct a modal space that contains only possible and non-trivially impossible worlds where it is not the case that “anything goes”. But I prove that it is impossible to develop an impossible-world framework that can do this job and that satisfies certain standard conditions. Effectively, I show that attempts to model moderately ideal agents in a world-involving framework collapse to modeling either logical omniscient agents, or extremely non-ideal agents. (shrink)

Anorexia Nervosa (AN) is an eating disorder characterised by self-starvation. Accounts of AN typically frame the disorder in individualistic terms: e.g., genetic predisposition, perceptual disturbances of body size and shape, experiential bodily disturbances. Without disputing the role these factors may play in developing AN, we instead draw attention to the way disordered eating practices in AN are actively supported by others. Specifically, we consider how Pro-Anorexia (ProAna) websites—which provide support and solidarity, tips, motivational content, a sense of community, and understanding (...) to individuals with AN—help drive and maintain AN practices. We use C. Thi Nguyen’s work on epistemic “echo chambers”, along with Maria Lugones’ work on “worlds” and “ease”, to explore the dynamics of these processes. Adopting this broader temporal and intersubjective perspective, we argue, not only helps to further illuminate the experiential character of AN but also has important clinical and therapeutic significance.

David Lewis holds that a single possible world can provide more than one way things could be. But what are possible worlds good for if they come apart from ways things could be? We can make sense of this if we go in for a metaphysical understanding of what the world is. The world does not include everything that is the case—only the genuine facts. Understood this way, Lewis's “cheap haecceitism” amounts to a kind of metaphysical anti-haecceitism: it says (...) there aren't any genuine facts about individuals over and above their qualitative roles.

A common understanding of the role of a game developer includes establishing (or at least partially establishing) what is interactively and perceptually available in (video)game environments: what elements and behaviors those worlds include and allow, and what is – instead – left out of their ‘possibility horizon’. The term ‘possibility horizon’ references the Ancient Greek origin of the term ‘horizon’, ὄρος (oros), which denotes a frontier – a spatial limit. On this etymological foundation, ‘horizon’ is used here to indicate (...) the spatial and operational boundaries that a (video)game environment affords its players. This book chapter discusses a particular feeling that emerge in relation to playful encounters with the ‘possibility horizons’ of videogames. I am referring here to the realization, as a player, that a game environment can be experientially exhausted and is, as such, ultimately banal. In other words, I will examine how our deliberate engagement with the interactive environments of digital games can trigger sensations that are analogous to what Romantic authors referred to as Weltschmerz (‘world-weariness’).

This article focuses on the role of servants in María Lugones’ “Playfulness, ‘World’-Travelling, and Loving Perception.” I show that Lugones uses and erases the work of servants in developing her understanding of world-traveling. This theoretical marginalization and instrumentalization challenges her claim to capture concrete, lived experience. This article argues that Lugones’ theory is “pseudo-concrete”: it capitulates into the very abstractions it seeks to overcome. Focusing on the role of servants reveals the class character of world-traveling and, in turn, its inability (...) to grasp class relations. This article, thus, invites decolonial feminists to reconsider the advantages of class analysis for understanding not only capitalist domination but also perception, identification, and love. -/- .

The “shrinking” of the globe in the last few centuries has made explicit that the world is a tense unity of many: the many worlds are forced to contend with one another. Nishida Kitarō, the founder of the Kyoto school, once stated that to be is to be implaced. We exist by partaking in “the socio-historical world.” More recently, Jean-luc Nancy has conceived of the world in terms of sense. What is striking in both is that the world emerges (...) out of a nothing, created ex nihilo—the phrase stripped of its theistic connotations. While for Nishida the world is ultimately implaced in the “place of absolute nothing,” Nancy speaks of the nothing that is the basis of the world’s self-creation. I will explore a possible convergence between these and any light it may shed upon our contemporary situation of globalization and its implications for praxis. I look to a sense of the nothing as a chōratic spatiality, an opening that provides space for co-being and serves as the source of creativity. In face of globalization, the project for meaning through mondialisation (in Nancy) and within a multi-cultural world (in Nishida) would imply the appropriation of such an originary spatiality.

One response to the problem of logical omniscience in standard possible worlds models of belief is to extend the space of worlds so as to include impossible worlds. It is natural to think that essentially the same strategy can be applied to probabilistic models of partial belief, for which parallel problems also arise. In this paper, I note a difficulty with the inclusion of impossible worlds into probabilistic models. Under weak assumptions about the space of (...) class='Hi'>worlds, most of the propositions which can be constructed from possible and impossible worlds are in an important sense inexpressible; leaving the probabilistic model committed to saying that agents in general have at least as many attitudes towards inexpressible propositions as they do towards expressible propositions. If it is reasonable to think that our attitudes are generally expressible, then a model with such commitments looks problematic. (shrink)

Abstract: Being-in-the-world defines in Heidegger an ontological and practical existential situation that in a first approach characterizes intellectual knowledge, an approach related to the Husserlian notion of intentionality. In his Curso de teoría del conocimiento, Polo rectifies this characterization, stressing the primacy of theory regarding action, and interpreting the practical (technical) relationship with the world as a lower level of “having”. Making some comparisons between Husserl, Scheler and Jonas, in connection with Polo’s thought, the article presents different accounts of the (...) notion of the world (phenomenological, metaphysical, moral) that allow to clarify the problem of the relationship between contemplation and action in the world.

Theorists who advocate worldly (metaphysical or ontological) indeterminacy—the idea that the world itself is indeterminate in one or more respects—should address how we understand the signifying nature and function of language in light of worldly indeterminacy. I first attend to Sengzhao and Jizang, two leading thinkers in Chinese Sanlun Buddhism, to reconstruct a Chinese Madhyamaka notion of ontic indeterminacy. Then, I draw on the thinkers’ views to propose a provisional (non-definitive) understanding of the nature and use of language. Under this (...) understanding, an expression signifying a thing is provisional in that the expression connotes no determinate feature of the thing. (shrink)

In this paper I explore the relationship between the idea of possible worlds and the notion of the beauty of God. I argue that there is a clear contradiction between the idea that God is utterly and completely beautiful on the one hand and the notion that He contains within himself all possible worlds on the other. Since some of the possible worlds residing in the mind of the deity are ugly, their presence seems to compromise God's (...) complete and utter beauty. (shrink)

In this paper I will draw attention to an important route to external world skepticism, which I will call confidence skepticism. I will argue that we can defang confidence skepticism (though not a meeker ‘argument from might’ which has got some attention in the 20th century literature on external world skepticism) by adopting a partially psychologistic answer to the problem of priors. And I will argue that certain recent work in the epistemology of mathematics and logic provides independent support for (...) such psychologism. (shrink)

I propose an account of possible worlds. According to the account, possible worlds are pluralities of sentences in an extremely large language. This account avoids a problem, relating to the total number of possible worlds, that other accounts face. And it has several additional benefits.

Many things can be other than they are. Many other things cannot. But what are statements like these about? One answer to this question is that we are speaking of possible worlds: if something can be other than it is, then it actually is that way in some possible world. If something cannot be otherwise, it is not otherwise in any world. This answer is presently dominant in analytical philosophy of language and logic. What are these worlds? David (...) Lewis famously claimed that every world exists, just like ours does: there is no difference between the other worlds and ours. In contrast, the medieval thinker John Buridan understands modal logic in terms of objects and causal powers in this world: if something can be other than it is, then there is a causal power that can make it that way. If it cannot, then no causal power—not even God—can alter it, at least without destroying its nature. As we’ll see, the Lewisian plurality is not possible on Buridan’s account; accordingly, a basic tenet of classical theism is untenable on Lewis’s metaphysics. In short, either the Lewisian plurality is incoherent, or a core monotheistic tenet is impossible. (shrink)

Among the most remarkable developments in metaphysics since the 1950’s is the explosion of philosophical interest in possible worlds. This paper proposes an explanation of what possible worlds are, and argues that this proposal, the interpreted models conception, should be attractive to anyone who thinks that modal facts are primitive, and so not to be explained in terms of some non-modal notion of “possible world.” I articulate three constraints on any acceptable primitivist explanation of the nature of possible (...) worlds, and show that the interpreted models conception meets the three constraints.

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many (...) applications, possible worlds face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

This chapter provides an introduction to possible worlds semantics in both logic and the philosophy of language, including a discussion of some of the advantages and challenges for possible worlds semantics.

Articolo divulgativo pubblicato su Immoderati il 10 novembre 2021. Inizio analizzando i criteri di legittimità dell'eutanasia normalmente accettati nella discussione etica filosofica.

World semantics for relevant logics include so-called non-normal or impossible worlds providing model-theoretic counterexamples to such irrelevant entailments as (A ∧ ¬A) → B, A → (B∨¬B), or A → (B → B). Some well-known views interpret non-normal worlds as information states. If so, they can plausibly model our ability of conceiving or representing logical impossibilities. The phenomenon is explored by combining a formal setting with philosophical discussion. I take Priest’s basic relevant logic N4 and extend it, on (...) the syntactic side, with a representation operator, (R), and on the semantic side, with particularly anarchic non-normal worlds. This combination easily invalidates unwelcome “logical omniscience” in- ferences of standard epistemic logic, such as belief-consistency and closure under entailment. Some open questions are then raised on the best strategies to regiment (R) in order to express more vertebrate kinds of conceivability. (shrink)

Logical analysis of the applicability of nominals (which are introduced by hybrid logic) in the formal descriptions of the world (within modern knowledge representation and semantics-based systems) is very important because nominals, as second sorts of propositional symbols, can support logical identification of the described world at specific [temporal and/or spacial] states. This paper will focus on answering the philosophical-logical question of ‘how a fundamental world description in description logic (DL) and a nominal can be related to each other?’. Based (...) on my assumption that nominals can support more adequate identification of the world in DL, this paper will deal with the concept of ‘world identification’. Accordingly, based on a logical-terminological analysis of nominals, the paper will analyse hybridised fundamental world descriptions. The research will finally reach the idea that we can have a hybrid description logic based on the analysed concepts. (shrink)

In ‘from times to worlds and back again: a transcendentist theory of persistence’ (henceforth TTP) Alessandro Giordani outlines five competitor views regarding the manner in which objects occupy regions along a dimension. These are: (1) classical uni-location (2) bare uni-location (3) multi-location (4) counterpart presence and (5) transcendent presence. Each view comes in both a temporal and modal version and Giordani argues that one ought to prefer transcendentism (i.e. 5) along both dimensions. According to temporal transcendentism, necessarily, no object (...) is exactly located at any region along the temporal dimension. Instead, any object, O, is derivatively present at some region, R, along the temporal dimension in virtue of bearing certain relations to something (according to TTP an event) that occupies R along that dimension. According to modal transcendentism, no object is exactly located at any region along the modal dimension. Instead, any object, O, is derivatively present at some region, R, along the modal dimension in virtue of bearing certain relations to something (according to TTP an event) that occupies R along that dimension. I argue that such a view is under motivated, and, at any rate, may not in fact offer a distinct view. (shrink)

This collection of essays discusses a central feature of European philosophy: the idea of a universal active power as the ultimate world-explanation.

What is the relationship between the world and logic, between intuition and language, between objects and their quantitative determinations? Rationalists, on the one hand, hold that the world is structured in a rational way. Representationalists, on the other hand, assume that language, logic, and mathematics are only the means to order and describe the intuitively given world. In World and Logic, Jens Lemanski takes up three surprising arguments from Arthur Schopenhauer’s hitherto undiscovered Berlin Lectures, which concern the philosophy of language, (...) logic, and mathematics. Based on these arguments, Lemanski develops a new position entitled ‘rational representationalism’: the world is always structured by human beings according to linguistic, logical, and mathematical principles, but the basic vocabulary of these structural descriptions already contains metaphors taken from the world around us.

‘Adams worlds’ are possible worlds that contain no creature whose life is not worth living or whose life is overall worse than in any other possible world in which it would have existed. Creating an Adams world involves no wrongdoing or unkindness towards creatures on the part of the creator. I argue that the notion of an Adams world is of little value in theodicy. Theists are not only committed to thinking that this world was created without wrongdoing (...) or unkindness but also must rule out the possibility that the world might have been better had God not existed. Nor is there much reason, independent of the availability of a satisfactory theodicy, for believing that the actual world is an Adams world. The need for a theodicy constructed along Leibnizian lines, incorporating the claim that this world is the best possible, is thus reinforced. (shrink)

Realists about possible worlds typically identify possible worlds with abstract objects, such as propositions or properties. However, they face a significant objection due to Lewis (1986), to the effect that there is no way to explain how possible worlds-as-abstract objects represent possibilities. In this paper, I describe a response to this objection on behalf of realists. The response is to identify possible worlds with propositions, but to deny that propositions are abstract objects, or indeed objects at (...) all. Instead, I argue that realists should follow Prior (1971) and others in treating higher-order quantification (e.g. quantification into predicate or sentence position) as a genuine form of quantification in its own right, and so in particular, not to be analysed in terms of first-order quantification over abstract objects. I argue that from this ‘higher-orderist’ perspective, there is a relatively straightforward answer to the question of how possible worlds-as-propositions succeed in representing possibilities.
