The Varieties of Agnosticism.Filippo Ferrari &Luca Incurvati -2021 -Philosophical Quarterly 72 (2):365-380.detailsWe provide a framework for understanding agnosticism. The framework accounts for the varieties of agnosticism while vindicating the unity of the phenomenon. This combination of unity and plurality is achieved by taking the varieties of agnosticism to be represented by several agnostic stances, all of which share a common core provided by what we call the minimal agnostic attitude. We illustrate the fruitfulness of the framework by showing how it can be applied to several philosophical debates. In particular, several philosophical (...) positions can be aptly conceived of as instances of agnosticism whilst retaining their differences and distinguishing features. (shrink)
Truth and Norms: Normative Alethic Pluralism and Evaluative Disagreements.Filippo Ferrari -2021 - Lanham: Lexington Books.detailsTruth and Norms develops a novel pluralistic view of the normative role that truth exerts on judgements. This view, labeled normative alethic pluralism, provides the best explanation of the variable normative significance that disagreement exhibits in different areas of discourse and is fully compatible with a minimalist conception of truth.
Normative Alethic Pluralism.Filippo Ferrari -2018 - In Jeremy Wyatt, Nikolaj Jang Lee Linding Pedersen & Nathan Kellen,Pluralisms in Truth and Logic. Cham, Switzerland and Basingstoke, Hampshire, UK: Palgrave Macmillan. pp. 145-168.detailsSome philosophers have argued that truth is a norm of judgement and have provided a variety of formulations of this general thesis. In this paper, I shall side with these philosophers and assume that truth is a norm of judgement. What I am primarily interested in here are two core questions concerning the judgement-truth norm: (i) what are the normative relationships between truth and judgement? And (ii) do these relationships vary or are they constant? I argue for a pluralist picture—what (...) I call Normative Alethic Pluralism (NAP)—according to which (i) there is more than one correct judgement-truth norm and (ii) the normative relationships between truth and judgement vary in relation to the subject matter of the judgement. By means of a comparative analysis of disagreement in three areas of the evaluative domain—refined aesthetics, basic taste and morality—I show that there is an important variability in the normative significance of disagreement—I call this the variability conjecture. By presenting a variation of Lynch’s scope problem for alethic monism, I argue that a monistic approach to the normative function of truth is unable to vindicate the conjecture. I then argue that normative alethic pluralism provides us with a promising model to account for it. (shrink)
Ecumenical alethic pluralism.Filippo Ferrari &Sebastiano Moruzzi -2019 -Canadian Journal of Philosophy 49 (3):368-393.detailsABSTRACTEcumenical Alethic Pluralism is a novel kind of alethic pluralism. It is ecumenical in that it widens the scope of alethic pluralism by allowing for a normatively deflated truth property alongside a variety of normatively robust truth properties. We establish EAP by showing how Wright’s Inflationary Arguments fail in the domain of taste, once a relativist treatment of the metaphysics and epistemology of that domain is endorsed. EAP is highly significant to current debates on the nature of truth insofar as (...) it involves a reconfiguration of the dialectic between deflationists and pluralists. (shrink)
Disagreement about Taste and Alethic Suberogation.Filippo Ferrari -2016 -Philosophical Quarterly 66 (264):516-535.detailsI present a novel strategy to account for two thoughts concerning disagreements about taste: (i) that they need not involve any substantive fault (faultlessness); (ii) that the faultlessness of a contrary opinion can be coherently appreciated from within a committed perspective (parity). Under the assumption that judgments of taste are truth-apt and governed by the truth-norm, I argue that understanding how exactly truth is normative offers a strategy for accounting for both thoughts. I distinguish between different ways in which truth (...) governs judgment to substantiate the thesis that truth’s normative function varies according to the subject matter at issue. I then argue that truth’s normative guidance in the domain of taste is characteristically weak. I introduce an intuitive distinction between basic and refined taste, and show how this distinction affects questions of faultlessness and parity. Last, I discuss the idea of alethic suberogation in connection with disagreement about refined taste. (shrink)
Introduction to the special issue “alethic pluralism and the normativity of truth”.Filippo Ferrari &Sebastiano Moruzzi -2020 -American Philosophical Quarterly 57 (4):309-310.detailsIn Truth and Objectivity, Crispin Wright argues that because truth is a distinctively normative property, it cannot be as metaphysically insubstantive as deflationists claim.1 This argument has been taken, together with the scope problem,2 as one of the main motivations for alethic pluralism.3 We offer a reconstruction of Wright’s Inflationary Argument (henceforth IA) aimed at highlighting what are the steps required to establish its inflationary conclusion. We argue that if a certain metaphysical and epistemological view of a given subject matter (...) is accepted, a local counterexample to IA can be constructed. We focus on the domain of basic taste and we develop two variants of a subjectivist and relativist metaphysics and epistemology that seems palatable in that domain. Although we undertake no commitment to this being the right metaphysical cum epistemological package for basic taste, we contend that if the metaphysics and the epistemology of basic taste are understood along these lines, they call for a truth property whose nature is not distinctively normative—contra what IA predicts. This result shows that the success of IA requires certain substantial metaphysical and epistemological principles and that, consequently, a proper assessment of IA cannot avoid taking a stance on the metaphysics and the epistemology of the domain where it is claimed to be successful. Although we conjecture that IA might succeed in other domains, in this paper we don’t take a stand on this issue. We conclude by briefly discussing the significance of this result for the debate on alethic pluralism. (shrink)
The value of minimalist truth.Filippo Ferrari -2018 -Synthese 195 (3):1103-1125.detailsSince the publication of Truth, Paul Horwich’s ‘Minimalism’ has become the paradigm of what goes under the label ‘the deflationary conception of truth’. Despite the many theoretical virtues of Horwich’s minimalism, it is usually contended that it cannot fully account for the normative role that truth plays in enquiry. As I see it, this concern amounts to several challenges. One such challenge—call it the axiological challenge—is about whether deflationists have the theoretical resources to explain the value of truth. Some philosophers (...) have argued that they do not. The thought is that by being valuable in the way it is, truth plays a non-trivial explanatory role with respect to core phenomena of enquiry. In order to account for this aspect of truth, the challenge goes, we need to inflate truth’s nature to an extent incompatible with core tenets of the minimalist conception. In this paper, I first provide some clarifications of what we mean exactly when we say that truth is valuable. By borrowing important distinction from the current debate in axiology, I elaborate a framework within which to conduct investigations into the value of truth. With reference to Horwich’s discussion of the issue, I then discuss the link between questions concerning the explanatory role of truth and the issue of its metaphysical inflation. I conclude by briefly exploring a few strategies on behalf of minimalists to address the axiological challenge. (shrink)
On Emergence, Again.Francesco Maria Ferrari &Mark H. Bickhard -2023 -Metaphysica 24 (2):381-406.detailsThe aim of the present paper is twofold. First, we are interested in assessing the validity of one version of Kim’s argument against genuine higher level causation. Second, we discuss Wilson’s proposal to consider a weaker notion of emergence as genuinely metaphysical and compatible with Non-Reductive Physicalism. Our conclusion is that both proposals fail: the first in preempting genuine (strong) emergent causation, whereas the second in ensuring a genuinely metaphysical status to weak emergence. After all, Wilson’s proposal strongly depends on (...) the success of Kim’s, not only because it takes it as valid but, also, because in pursuing its own weaker model it shares the presuppositions that led Kim’s to failure. At the end of the day, Wilson’s conception of genuine weak emergence either breaks causal closure or is merely stipulative, namely confined at the descriptive level. (shrink)
An argument against nominalism.Francesco Maria Ferrari -2022 -Synthese 200 (5):1-23.detailsNominalism in formal ontology is still the thesis that the only acceptable domain of quantification is the first-order domain of particulars. Nominalists may assert that second-order well-formed formulas can be fully and completely interpreted within the first-order domain, thereby avoiding any ontological commitment to second-order entities, by means of an appropriate semantics called “substitutional”. In this paper I argue that the success of this strategy depends on the ability of Nominalists to maintain that identity, and equivalence relations more in general, (...) is first-order and invariant. Firstly, I explain why Nominalists are formally bound to this first-order concept of identity. Secondly, I show that the resources needed to justify identity, a certain conception of identity invariance, are out of the Nominalist’s reach. (shrink)
Formal Issues of Trope-Only Theories of Universals.Francesco Maria Ferrari -2022 -Erkenntnis 89 (3):919-946.detailsThe paper discusses some formal difficulties concerning the theory of universals of Trope-Only ontologies, from which the formal theory of predication advanced by Trope-Only theorists seems to be irremediably affected. It is impossible to lay out a successful defense of a Trope-Only theory without Russellian types, but such types are ontologically inconsistent with tropes’ nominalism. Historically, Tropists’ first way to avoid the problem is appealing to the supervenience claim, which however fails on its terms and, thus, fails as a ground (...) for a solution to the higher-order or ‘type’ problem. A later solution involves the invariance of primitive equivalence relations in order to make universals ontologically innocuous. However, I argue that this latter solution fails to meet the requirements imposed on an ontologically unbiased nominalist attitude. So, this paper discusses how Trope-Only theories alter standard formal moves in Nominalism, and also is interested in clarifying further the formal assumptions for these problems. (shrink)

Disagreement and suspended judgement.Filippo Ferrari -2022 -Metaphilosophy 53 (4):526-542.detailsCan someone who suspends judgement about a certain proposition <p> be in a relational state of disagreement with someone who believes <p> as well as with some- one who disbelieves <p>? This paper argues for an af- firmative answer. It develops an account of the notions of suspended judgement and disagreement that explains how and why the suspender is in a relational state of disagreement with both the believer and the disbeliever about the very same proposition <p>. More specifically, the (...) paper first provides a characterisation of the norma- tive profile associated with the state of suspended judge- ment in terms of the set of normative commitments that it engenders in the context of inquiry. It then provides a characterisation of the notion of disagreement in terms the incompatibility between the sets of normative com- mitments characteristic of the three states in question— belief, disbelief, and suspension.

Assessment–Sensitivity.Filippo Ferrari -2016 -Analysis 76 (4):516-527.detailsIn this paper I offer some critical comments to MacFarlane's recent book "Assessment Sensitivity". I focus primarily on MacFarlane's understanding of the normative aspects of enquiry—in particular I take issue with the phenomena of retraction and disagreement as preclusion of joint accuracy. I argue that both notions are problematic and that—at least in the case of basic taste—they are not needed in order to account for our intuitions.
Deflating truth about taste.Filippo Ferrari &Sebastiano Moruzzi -2020 -American Philosophical Quarterly 57 (4):389-402.detailsIn Truth and Objectivity, Crispin Wright argues that because truth is a distinctively normative property, it cannot be as metaphysically insubstantive as deflationists claim. We offer a reconstruction of Wright’s Inflationary Argument that highlights the steps required to establish its inflationary conclusion. We argue that if a certain metaphysical and epistemological view of a given subject matter is accepted, a local counterexample to the Inflationary Argument can be constructed. As a case study we focus on the domain of basic taste. (...) We develop two variants of a subjectivist and relativist metaphysics and epistemology that seem palatable in that domain and we show that the Inflationary Argument doesn’t go through in the domain of basic taste thus construed. We conclude by briefly discussing the significance of this result for the debate on alethic pluralism. (shrink)
Alethic Pluralism and the Value of Truth.Filippo Ferrari -2020 -Synthese 199 (1):1–25.detailsI have two objectives in this paper. The first is to investigate whether, and to what extent, truth is valuable. I do this by first isolating the value question from other normative questions. Second, I import into the debate about the nature of truth some key distinctions hailing from value theory. This will help us to clarify the sense in which truth is valuable. I then argue that there is significant variability in the value of truth in different areas of (...) discourse. I shall call this the axiological variability conjecture. I illustrate and substantiate AVC by contrasting the occurrence of disagreement in two paradigmatically evaluative areas of discourse, viz. matters of taste, on the one hand, and morality, on the other. I claim that there is a reasonable tendency to care much more about settling moral disagreements than taste disagreements and that this difference has to do, at least partly but significantly, with the different value that truth exhibits in these two areas of discourse. I then turn to the second objective of the paper—namely, to discuss how pluralistic accounts of the nature of truth may deal with the value of truth in light of AVC. I will argue that AVC is a problem for all versions of truth pluralism that are committed to the following two theses: that truth is a value concept; and that this characteristic of the concept has to be reflected in the metaphysical nature of any admissible truth properties—i.e., all the various properties that are admissible in the pluralist account are value-conferring properties and thus intrinsically valuable. In so doing, I will focus primarily on Michael Lynch’s functionalist incarnation of truth pluralism. Lynch terms this “Manifestation Alethic Pluralism”. My reason for this is twofold: first and foremost, MAP is a paradigmatic exemplification of a model of truth pluralism that is committed to both and ; second, MAP has, to date, enjoyed the most discussion, and currently provides the most developed account of truth pluralism. However, I argue that MAP lacks the resources to account for AVC. Owing to this, I suggest two ways out for an advocate of MAP, which force various structural changes in her view. (shrink)
Assessment Relativism.Filippo Ferrari -2019 - In Martin Kusch,The Routledge Handbook of Philosophy of Relativism. Routledge.detailsAssessment relativism, as developed by John MacFarlane, is the view that the truth of our claims involving a variety of English expressions—‘tasty’, ‘knows’, ‘tomorrow’, ‘might’, and ‘ought’—is relative not only to aspects of the context of their production but also to aspects of the context in which they are assessed. Assessment relativism is thus a form of truth relativism which is offered as a new way of understanding perspectival thought and talk. In this article, I present the main theses of (...) assessment relativism, focusing in particular on highlighting the points of commonality and contrast with other forms of truth relativism. I then offer some critical remarks concerning the motivation of assessment relativism in relation to matters of taste. (shrink)

The Nominalist Limit of Kim’s Ontological Physicalism.Francesco Maria Ferrari -2024 -Metaphysica 25 (2):311-338.detailsKim’s Ontological Physicalism (OP) presents itself as a naturalistic and monistic metaphysical framework, aligned with the causal closure of the universe and rejecting causally efficacious “exotic” properties. The foundational ontology is, in turn, monistic and materialistic, positing that the universe is composed solely of material particulars: bits of matter. In this work, we identify a notable tension between OP’s intended model and the one OP specifies. Initially, we show how the theory inevitably becomes entangled with higher-order entities, not just particulars. (...) Kim introduces the Supervenience Argument (SA) to counteract the possibility of higher-order entities being causally efficacious. While SA proves to be a plausible strategy, it is ultimately inadequate: not only SA is a petitio principii against emergence, but it is also unsound and invalid. Therefore, we propose a formal strategy to restore its ontological effectiveness. Unfortunately, at a closer look, even this strategy falls short as it unwarrantedly assumes the logicality and invariance of those equivalence relations (such as identity, similarity, and congruence) which are crucial for specifying the theory’s model as composed of particulars.

Proof-theoretic pluralism.Filippo Ferrari &Eugenio Orlandelli -2019 -Synthese 198 (Suppl 20):4879-4903.detailsStarting from a proof-theoretic perspective, where meaning is determined by the inference rules governing logical operators, in this paper we primarily aim at developing a proof-theoretic alternative to the model-theoretic meaning-invariant logical pluralism discussed in Beall and Restall. We will also outline how this framework can be easily extended to include a form of meaning-variant logical pluralism. In this respect, the framework developed in this paper—which we label two-level proof-theoretic pluralism—is much broader in scope than the one discussed in Beall (...) and Restall’s book. (shrink)
(1 other version)Substance Metaphysics is Incompatible with the Causal Closure of the Metaphysical Realm.Francesco Maria Ferrari -2023 -Ética E Filosofia Política 1 (26):78-102.detailsThe present paper argues that substantialist metaphysics are in tension with the physicalist idea that the universe is causally closed. The argument is a rather specific one and proceeds through three steps. The first step consists in arguing that monistic substance metaphysics allow for the existence of entities that cannot belong to the intended first order domain. This result sensitively depends on the nature of substances as invariant entities. The second step concludes that, if further domains are to be admitted, (...) then they are inhabited by “higher” or (systematically) “non-standard” entities and that, in both cases if not made somehow innocuous, such entities may take part on the metaphysical construction of the world through their own distinctive properties and causal powers. However, this latter claim is in contradiction with causal closure. But closure is the principle that mainly characterizes physicalist approaches in metaphysics and as such physicalist metaphysics cannot get rid of it. Who attempted making exotic properties and causal powers innocuous usually appealed to the Supervenience Argument. Unfortunately, as the third step proves, this argument is invalid. Finally, the paper looks forward and toward alternative models for physicalist metaphysics, like process-based models. (shrink)

Epistemologia non-ideale. Il modello dei filtri epistemici.Filippo Ferrari &Sebastiano Moruzzi -2024 -Rivista di Filosofia 115 (2):319-339.detailsIn this article, we explore the impact of non-epistemic factors, such as social identity and cultural biases, on the formation and revision of beliefs. This type of impact is evident in contexts of opinion polarisation where the acceptance of scientific theses by groups of non-experts is at stake. Im these contexts digital media and social networks often play a central role. To analyse the impact of non-epistemic factors from an epistemological perspective, we employ a non-ideal approach to epistemology that takes (...) into account some key non-epistemic factors through the concept of epistemic filter. By means of this concept we explain the selective acceptance of information, and we show how background assumptions and social values which are deeply rooted in an inquiring subject influence the selection and evaluation of evidence and sources of information. Through this non-ideal approach, we analyse the dynamics of scientific denialism, framing it as an epistemic phenomenon in which social and cultural influences shape and distort epistemic practices. We conclude that understanding these underlying mechanisms is crucial to addressing the challenges posed by misinformation and the deep social divisions that result from it. (shrink)

(1 other version)PROCESS-BASED ENTITIES ARE RELATIONAL STRUCTURES. From Whitehead to Structuralism.Francesco Maria Ferrari -2021 -Manuscrito 44 (1):149-207.detailsThe aim of this work is to argue for the idea that processes and process-based entities are to be modelled as relational structures. Relational structures are genuine structures, namely entities not committed to the existence of basic objects. My argument moves from the analysis of Whitehead’s original insight about process-based entities that, despite some residual of substance metaphysics, has the merit of grounding the intrinsic dynamism of reality on the holistic and relational characters of process-based entities. The current model of (...) process ontology requires genuine emergence and this, in turn, requires organizations, i.e., emergence in organizations. Another view about processes rely on a structural specification of processes. I suggest that the two views can be made compatible by the help of a specific sort of structures, namely relational structures. The appeal to the mathematical theory of genuine structures, category theory, reveals the formal plausibility of this convergence. According to this formal approach, genuine structures are essentially dynamic entities for they are relational, namely, as well as organizations, they are not existentially committed to particulars.

Radical relativism, retraction and "being at fault".Filippo Ferrari &Dan Zeman -2014 - In Fabio Bacchini, Stefano Caputo & Massimo Dell'Utri,New Frontiers in Truth. Cambridge Scholar. pp. 80-102.detailsRadical relativism was born with a promise: to account for certain phenomena that opposite views are unable to explain. One example is the phenomenon of “faultless disagreement”, according to which two people, while disagreeing, are not at fault in any substantive way. The phenomena of retraction and assessments of truth in cases of eavesdropping are others. All these phenomena have been claimed to pose serious problems for rival views and be best accounted for within a radical relativistic framework. While “faultless (...) disagreement” and the notion of disagreement in general has benefited from extensive discussion in current debates over semantic content, retraction has not been in the spotlight that much. In particular, very few things have been said about what retraction exactly amounts to and how to conceive of its normative profile. This will be the focus of our paper. (shrink)
Verità e Post-Verità: dall'Indagine alla Post-Indagine.Filippo Ferrari &Sebastiano Moruzzi -2020 - Bologna: 1088 Press & Bononia University Press. Edited by Sebastiano Moruzzi.detailsIn this book, we interpret post-truth as a multifaceted phenomenon which involves fake news, emotion-driven rhetoric (vs fact-driven discussion), credulism in the social-media, conspiracy theories and scientific denialism. We develop three models intended to represent the multifaceted nature of post-truth in terms of deviated forms of enquiry – which we label “post-enquiries”. The first form of post-enquiry posits the existence of alternative facts; the second prioritizes emotions over facts; the third limits the scope of the norms of enquiry. We elaborate (...) on the third model in relation to scientific denialism and we apply it to analyse the case of flat-earthism. (shrink)
Enquiry and Normative Deviance The Role of Fake News in Science Denialism.Filippo Ferrari &Sebastiano Moruzzi -2021 - In Sven Bernecker, Amy K. Flowerree & Thomas Grundmann,The Epistemology of Fake News. New York, NY: Oxford University Press.detailsThe main thesis of this paper is that science denialism brings about an aberrant form of enquiry in which the epistemic norms governing scientific enquiry are deviated in significant ways. Science denialism doesn’t involve just a rejection of a scientific theory; it also deeply challenges the practice, common within scientific enquiry, of continuously and, to a certain extent, impartially testing research methods, theories, and evidential sources with the aim of improving the accuracy of our theories. We will offer an in-depth (...) analysis of the epistemic mechanisms underpinning the normative aberration brought about by science denialism. More specifically, we will develop a fine-grained framework to model a variety of normative deviances that may take place in enquiry. By analysing two case studies, we will argue that fake news contributes significantly to shape the epistemic norms operating within science denialism. They in fact play two pivotal roles: first, they are used to cast discredit on a variety of (institutional) sources of evidence in relation to a certain set of phenomena (e.g. whether vaccines are safe for our health); second, they also play a part in building the alternative explanation of the targeted phenomena.

Some Notes on the Role of the Identity of Indiscernibles in Metaphysics.Francesco Maria Ferrari -2024 -Revista Portuguesa de Filosofia 80 (4):1215-1242.detailsThe Principle of the Identity of Indiscernibles (PII) asserts that if putative objects x and y share all properties P, then they must be one and the same entity. Since the usual formal rendering of the PII has the same formal structure as the Leibniz Identity, it may be unclear whether it can be used to define identity and objectuality. As identity and objectuality are closely related, this study aims to examine their relationship within the framework of formal ontology. Crucial (...) for the discussion are issues about type and range of quantification and the invariance of the identity predicate coourring in the PII. Ultimately, the analysis reveals that the appeal to PII is insufficient for providing both identity and objectuality. Some further considerations about how the PII sensitively constrains the range of available ontologies or metaphysics are formulated. (shrink)
Disagreement and the Normativity of Truth beneath Cognitive Command.Filippo Ferrari -2014 - Dissertation, University of AberdeendetailsThis thesis engages with three topics and the relationships between them: (i) the phenomenon of disagreement (paradigmatically, where one person makes a claim and another denies it); (ii) the normative character of disagreements (the issue of whether, and in what sense, one of the parties is “at fault” for believing something that’s untrue); (iii) the issue of which theory of what truth is can best accommodate the norms relating belief and truth. People disagree about all sorts of things: about whether (...) climate is changing, death penalty is wrong, sushi is delicious, or Louis C.K. is funny. However, even focusing on disagreements in the evaluative domain (e.g., taste, moral and comedic), where people have the intuition that there is ‘no fact of the matter’ about who is right, there are significant differences that require explanation. For instance, disagreement about taste is generally perceived as shallow. People accept to disagree and live comfortably with that fact. By contrast, moral disagreement is perceived as deep and sometimes hard to tolerate. Comedic disagreement is similar to taste. However, it may involve an element of ‘intellectual snobbery’ that is absent in taste disagreement. The immediate questions are whether these contrasts allow of precise characterization and what is responsible for them. I argue that, once a case is made for the truth-aptness of judgments in these areas, the contrast can be explained in terms of variable normative function of truth – as exerting a lightweight normative constraint in the domain of taste and a stricter constraint in the moral domain. In particular I claim that while truth in the moral domain exerts a sui generis deontic control, this normative feature of truth is silent in both the taste and the comedic domains. This leads me to investigate how to conceive of truth in the light of normative variability. I argue that an amended version of deflationism – minimally inflated deflationism – can account for the normative variability of truth. (shrink)

Some Notes on Boolos’ Semantics: Genesis, Ontological Quests and Model-Theoretic Equivalence to Standard Semantics.Francesco Maria Ferrari -2018 -Axiomathes 28 (2):125-154.detailsThe main aim of this work is to evaluate whether Boolos’ semantics for second-order languages is model-theoretically equivalent to standard model-theoretic semantics. Such an equivalence result is, actually, directly proved in the “Appendix”. I argue that Boolos’ intent in developing such a semantics is not to avoid set-theoretic notions in favor of pluralities. It is, rather, to prevent that predicates, in the sense of functions, refer to classes of classes. Boolos’ formal semantics differs from a semantics of pluralities for Boolos’ (...) plural reading of second-order quantifiers, for the notion of plurality is much more general, not only of that set, but also of class. In fact, by showing that a plurality is equivalent to sub-sets of a power set, the notion of plurality comes to suffer a loss of generality. Despite of this equivalence result, I maintain that Boolos’ formal semantics does not committ second-order languages to second-order entities, contrary to standard semantics. Further, such an equivalence result provides a rationale for many criticisms to Boolos’ formal semantics, in particular those by Resnik and Parsons against its alleged ontological innocence and on its Platonistic presupposition. The key set-theoretic notion involved in the equivalence proof is that of many-valued function. But, first, I will provide a clarification of the philosophical context and theoretical grounds of the genesis of Boolos’ formal semantics. (shrink)
Perspectives on Post-Truth.Filippo Ferrari,Anna Maria Lorusso,Sebastiano Moruzzi &Giorgio Volpe -2023 -Social Epistemology 37 (2):141-149.detailsThis opening piece of the special issue ‘Perspectives on Post-Truth’ aims to accomplish three tasks. First, and foremost, it highlights the issue’s distinctive feature, namely its variegated approach to post-truth. The leading idea in assembling it has been to draw on different methodologies, theoretical approaches, and competences, in order to gain a fine-grained understanding of the post-truth condition and to develop an effective toolkit to address the most pressing challenges it poses to our societies. The underlying conviction is that a (...) variegated approach is required by the multifaceted nature of the post-truth condition. The curious reader willing to venture through the issue will thus be exposed to different perspectives on post-truth: some pieces address it from a traditional epistemological perspective, others explore post-truth from the perspective of social epistemology, and still others adopt a semiotic perspective. In light of this multiplicity of perspectives, the second task of this piece has been to provide a brief thematic overview of the key issues and perspectives in order to illustrate the overall narrative of the project. The third and final task has been to give a detailed synopsis of each contribution so that the reader will know precisely what to expect from it. (shrink)
Platone ha effettivamente identificato il demiurgo del Timeo e l’idea del bene della Repubblica?Franco Ferrari -2017 -Chôra 15:67-91.detailsUn debat tres vif eut lieu parmi les commentateurs medioplatoniciens sur le rapport entre la forme du bien de la Republique et le demiurge du Timee. Certains d’entre eux, comme Plutarque et Atticus, parvinrent a identifier ces deux entites, d’autres, comme Numenius, a situer les deux principes dans une relation hierarchique, en attribuant au bien la qualification de ≪premier dieu≫ et de pere et au demiurge celle de ≪second dieu≫ et de producteur. Cet article se propose d’examiner la question de (...) l’identite de la forme du bien avec le demiurge sur des bases nouvelles, en prenant comme point de depart une interpretation metaphorique de la figure du demiurge, qui ne se presente pas comme un principe metaphysique independant, mais comme une description metaphorique de l’element causal‑efficient du monde des formes, c’est a dire du vivant intelligible. Le demiurge coinciderait donc avec la totalite active et dynamique du monde intelligible. Dans la seconde partie de l’article est prise en consideration l’hypothese que la superiorite de la forme du bien par rapport aux autres formes est du meme genre que celle du demiurge, dans la mesure ou le bien aussi peut etre compris comme la totalite du kosmos intelligible. Il s’agit d’une hypothese qui ne va pas sans difficultes, mais qui merite d’etre examinee jusqu’au bout. (shrink)
Post-Enquiry and Disagreement. A Socio-Epistemological Model of the Normative Significance of Disagreement Between Scientists and Denialists.Filippo Ferrari &Sebastiano Moruzzi -2023 -Social Epistemology 37 (2):177-196.detailsIn this paper we investigate whether and to what extent scientists (e.g. inquirers such as epidemiologists or virologists) can have rational and fruitful disagreement with what we call post-enquirers (e.g. conspiratorial anti-vaxxers) on topics of scientific relevance such as the safety and efficacy of vaccines. In order to accomplish this aim, we will rely and expand on the epistemological framework developed in detail in Ferrari & Moruzzi (2021) to study the underlying normative profile of enquiry and post-enquiry. We take it (...) that our analysis provides an effective explanation of why standard argumentative strategies such as fact-checking and debunking cannot work in the context of disagreement between scientists and denialists unless they are coupled with a discussion of the values that are endorsed by the scientific community.

For theorists of truth, answering the question of whether truth is natural will tell us more about the nature of truth (or lack of it), and the relations between truth and other properties of interest. For those working on naturalism who wish to have truth as part of the natural order, answering this question is of paramount importance. In this chapter, (...) we focus primarily on the kinds of theory of truth that occupy the central positions in current debates about truth, namely correspondence theories, deflationary theories, epistemic theories, and pluralist theories, and aim to discern the extent to which truth is a natural property on each view.

Il proemio di Timeo: struttura, contenuto e funzione.Franco Ferrari -2023 -Méthexis 35 (1):29-52.detailsIn the proem that precedes the account of the generation of the world, Timaeus provides very important elements for understanding the discourse he is about to delivery. It is a complex text that displays at least three different levels: dialectical, analogical (or metaphorical) and epistemological. In the dialectical section, Timaeus establishes that the sensible universe is a generated reality and as such has a cause; in the metaphorical section, he indicates the analogical schemes he will use to explain the genesis (...) of the cosmos (technical and biological) and the causes on which it depends. Finally, in the epistemological section he explains the reason why this exposition cannot achieve truth but must be content with likeness. (shrink)

Knowledge and virtue in Plato's Meno.Franco Ferrari -2014 -Archai: Revista de Estudos Sobre as Origens Do Pensamento Ocidental 12:77-83.detailsO tema da natureza da virtude e de sua transmissibilidade atravessa quase todos os diálogos da juventude de Platão, isto é, os considerados “diálogos socráticos”. Este adquire uma relevância central no Protágoras e no Mênon, o qual se abre exatamente com a interrogação acerca da maneira de adquirir a virtude. No curso do diálogo, a arete assume um significado eminentemente político: Mênon pergunta a Sócrates como se pode obter sucesso no campo político, como se pode adquirir reconhecimento social. A tese (...) em torno a qual se desenvolve a conversação assume a identidade de virtude e conhecimento (episteme). Todavia, a consequência que deriva da assunção desta tese, isto é, o princípio com base no qual a virtude, enquanto conhecimento, seja ensinável, é refutado por meio do célebre “argumento empírico”: a ausência de homens capazes de transmitir a sua virtude aos filhos demonstra que essa não é ensinável, e ,portanto, não é conhecimento. Sócrates propõe, então, situar na opinião correta (orthe doxa) a fonte da virtude política. Todavia, a validade do argumento empírico resulta muito incerta, uma vez que parece fundar-se na ambiguidade do significado do termo didakton, que quer dizer seja “ensinável” seja efetivamente “ensinado”. Também a tentativa de fundar a virtude na theia moira deve ser tratada com certo ceticismo. Na realidade, Sócrates alude, no fim do diálogo, à possibilidade de que exista um homem que seja virtuoso e que seja também capaz de ensinar a virtude a outro homem: este homem extraordinário é naturalmente o próprio Sócrates.

What is Deconstruction? An Interview with Jean-Luc Nancy, translated by Filippo Pietrogrande.Federico Ferrari &Jean-Luc Nancy -2020 -Derrida Today 13 (2):236-253.detailsIn this interview 1, Jean-Luc Nancy retraces the origin, the affirmation and the trivialisation of deconstruction: from its point of departure in Heidegger's project of the destruction of the history of ontology, to its attachment to Derrida's philosophical style; from its quick dissemination in the American universities and its adoption as a method of textual critique, to its gradual banalisation in common discourse as a synonym of ‘demolition’. All this is discussed through the lens of Nancy's personal experience, with particular (...) attention to the historical background and some insights into the origins of the project of a deconstruction of Christianity, the relation between deconstruction and différance and the future role of deconstruction.

Essere, gerarchia e causalità nell’ontologia di Platone. Un’introduzione.Franco Ferrari -2023 -Quaestio 22:21-38.detailsAlthough the term ontology is absent from Plato’s works, his thinking undoubtedly belongs to the prehistory of this discipline. In his dialogues, one finds many observations concerning what exists and how it exists. Plato’s metaphysics is based on the fundamental distinction between two kinds of entities, namely intelligible forms and sensible particulars. This diairesis is presented in different but all compatible ways. The ontological difference between forms and sensible objects implies a causal priority: according to Plato, this priority corresponds to (...) the proteron-hysteron scheme mentioned by Aristotle. The last part of the essay is devoted to the idea of the good and the problems related to its ontological status. (shrink)

Logic and Science: An Exploration of Logical Anti-Exceptionalism.Filippo Ferrari &Massimiliano Carrara -2025 - Cambridge: Cambridge University Press.detailsThis Element delves into the relationship between logic and the sciences, a topic brought to prominence by Quine, who regarded logic as methodologically and epistemologically akin to the sciences. For this reason, Quine is seen as the forefather of anti-exceptionalism about logic (AEL), a stance that has become prevalent in the philosophy of logic today. Despite its popularity and the volume of research it inspires, some core issues still lack clarity. For one thing, most works in the debate remain vague (...) on what should count as logic and what should count as a science. Furthermore, the terms of the comparison are rarely specified and discussed in a systematic way. This Element purports to advance the debate on these crucial issues with the hope of fostering our understanding of the fundamentals of AEL. (shrink)
