  1. A Simple Notion of Validity for Alethic Pluralism.Andrea Strollo - 2018 - Synthese 195 (4):1529-1546.
    Alethic pluralism holds that there are many truth properties. The view has been challenged to make sense of the notion of logical validity, understood as necessary truth preservation, when inferences involving different areas of discourse are concerned. I argue that the solution proposed by Edwards to solve the analogous problem of mixed compounds can straightforwardly be adapted to give alethic pluralists also a viable account of validity.

    Alethic Pluralism, Logical Validity, and Natural Truth.Andrea Strollo - 2021 - Philosophia 50 (1):269-284.
    Alethic pluralism holds that there are many ways of being true. The view has been accused of being unable to do justice to the traditional account of logical validity, understood as necessary truth preservation. In this paper I reformulate the debate in terms of the naturalness of generic truth, and discuss some notable consequences of this more careful reformulation. I show not only that some alleged solutions, like the resort to plural quantification, are ineffective, but also that the problem is (...)

    Truth Pluralism and Many-Valued Logic: Lesson from Suszko’s Thesis.Andrea Strollo - 2021 - Philosophical Quarterly 72 (1):155-176.
    According to truth pluralism, sentences from different areas of discourse can be true in different ways. This view has been challenged to make sense of logical validity, understood as necessary truth preservation, when inferences involving different areas are considered. To solve this problem, a natural temptation is that of replicating the standard practice in many-valued logic by appealing to the notion of designated values. Such a simple approach, however, is usually considered a non-starter for strong versions of truth pluralism, since (...)

    Deflationism and the Invisible Power of Truth.Andrea Strollo - 2013 - Dialectica 67 (4):521-543.
    In recent decades deflationary theories of truth have been challenged with a technical argument based on the notion of conservativeness. In this paper, I shall stress that conservative extensions of theories and expandability of their models are not equivalent notions. Then, I shall argue that the deflationary thesis of the unsubstantiality of truth is better understood as leveraging on the stronger notion of expandability of models. Once expandability is involved in the argument, some notable consequences follow: the strategy proposed by (...)

  5. Algebraic Semantics and Mixed Validities: A Reply to Cotnoir.Andrea Strollo - 2018 - Logique Et Analyse 61.
    Alethic pluralism holds that there are many ways of being true. Such a view has been challenged to make sense of the standard account of logical validity as necessary truth preservation. In this paper, the recent solution elaborated by Aaron Cotnoir, based on an algebraic approach, is shown to be untenable. Some reflections about the relation of many-valued logics with truth pluralism are also discussed.

    The Force of Alethic Pluralism.Andrea Strollo - 2020 - American Philosophical Quarterly 57 (4):325-336.
    Belief, according to many philosophers, aims at truth. In this paper I discuss in what measure a pluralist conception of truth is compatible with this claim. In particular, I argue that if the idea is understood according to a teleological account, alethic pluralism can be adopted also in a strong form. I contend that while the teleological account of belief requires a generic concept of truth, it poses a few constraints on the property (or the properties) of truth. By contrast, (...)

    Truth and the Metaphysics of Semantic and Logical Notions.Andrea Strollo - 2023 - Revista Portuguesa de Filosofia 79 (3):917-936.
    In contemporary philosophy, it is tempting to apply the metaphysics of properties to the specific case of truth, in the hope of making progress on the investigation of the latter. In this paper, I argue that a different approach, mostly independent from the metaphysics of properties and based on the naturalness, in Lewis’ sense, of semantic nations, is often a better alternative, both in general and in some specific cases. In particular, adopting the new perspective, I present a new problem (...)

    Truth and the Unity of Logical Validity.Andrea Strollo - forthcoming - Logic and Logical Philosophy:1-25.
    According to a traditional view, logical validity consists in necessary truth preservation. Such an account has been argued to carry an apparent commitment to a unique property of truth to be preserved from premises to conclusion. Recent discussions, however, have concluded that if the metaphor of truth preservation is carefully unpacked, no need for a unique property is there. All is needed is that certain structural relations among instantiations of truth properties hold. Against this view, we argue that a unique (...)

  9. DLEAC and the Rejection Paradox.Massimiliano Carrara & Andrea Strollo - 2021 - Journal of Applied Logics 8 (2):377-396.
    In this paper we first develop a Dialetheic Logic with Exclusive Assumptions and Conclusions, DLEAC. We adopt the semantics of the logic of paradox (LP) extended with a notion of model suitable for DLEAC, and we modify its proof theory by refining the notions of assumption and conclusion, which are understood as speech acts. We introduce a new paradox – the rejectability paradox – first informally, then formally. We then provide its derivation in an extension of DLEAC contanining the rejectability (...)

    Truth (bearers) pluralism.Andrea Strollo - 2023 - Synthese 201 (4):1-20.
    As for many other properties, to understand the nature of truth attention should be paid to the kind of entities that are apt to bear it. In particular, I argue that different kinds of truth bearers tend to support different properties of truth. After that, I show that there are reasons to admit a plurality of truth bearers. As a consequence of these two results, a plurality of truth properties may be naturally admitted. The general upshot of the paper is (...)

  11. How Simple Is the Simplicity of Truth? Reconciling the Mathematics and the Metaphysics of Truth.Andrea Strollo - 2014 - In Fabio Bacchini, Stefano Caputo & Massimo Dell'Utri (eds.), New Frontiers in Truth. Cambridge Scholar. pp. 161-175.
    The notion of truth is a central subject both in Philosophy and Mathematical Logic. The logical approach on the one side and the philosophical one on the other, however, mostly deal with problems which, apparently, require different tools to be tackled. In this paper I argue that such a separation can and should be overcome, and, in order to build a bridge, I focus on the philosophical issue of the insubstantiality of truth, which is a crucial topic to distinguish inflationist (...)

    If I Were Kripke … Attributive Names and the Necessary A Posteriori.Andrea Strollo - 2019 - Philosophical Forum 50 (1):117-134.
    According to Naming and Necessity, proper names usually work referentially as rigid designators. In this paper, I argue that proper names have also attributive uses that systematically emerge in particular contexts. Attributive uses are then exploited to show that simple identity claims (such as “Hesperus is Phosphorus”) are open to a double interpretation. The main aim of the paper is arguing that the impression that certain true identities are a posteriori is mostly due to one of the two readings, a (...)

Lezioni Padovane di Graham Priest Ed Altri Saggi Su L Dialeteismo. Padua, Province of Padua, Italy: Padova University Press. pp. 156-190.
    In questo articolo sviluppiamo una Logica Dialeteista con Assunzioni e Conclusioni Esclusive, DLEAC. A questo scopo, verrà adottata la semantica della Logica del Paradosso (LP), estesa definendo una specifica nozione di modello. L’apparato deduttivo viene modificato specificando le nozioni di Assunzione e Conclusione, considerate come atti linguistici. Successivamente, introduciamo un nuovo paradosso — il paradosso del diniego —, sia informalmente che formalmente, derivandolo all’interno di un’estensione di DLEAC concepita apposta per esprimerlo. Un tale paradosso rappresenta un serio problema per il (...)

    Intervistati sul valore di questo testo, gli autori hanno dichiarato: «o questa affermazione è falsa, oppure questo è il miglior eserciziario di logica che sia mai stato scritto». Se la loro affermazione vi risulta poco comprensibile, ma avete intenzione di capirci qualcosa di più, questo eserciziario può fare al caso vostro! È uno strumento che integra ed estende un comune manuale di logica – ma che non si sostituisce ad esso, mancando la parte teorica –, ed è pensato per coloro (...)

  15. A case for satisfaction classes: model theoretic vs axiomatic approaches to the notion of truth.Andrea Strollo - 2013 - Logical Investigations 19:246-259.
    One of the basic question we can ask about truth in a formal setting is what, if anything, we gain when we have a truth predicate at disposal. For example, does the expressive power of a language change or does the proof strength of a theory increase? Satisfaction classes are often described as complicated model theoretic constructions unable to give useful information toward the notion of truth from a general point of view. Their import is narrowed to a dimension of (...)

  16. Analytic Metaphysics should not go.Andrea Strollo - 2017 - Philosophical Inquiries 5 (2):33-53.
    Recently, analytic metaphysics has been attacked from a scientist’s perspective. In Everything Must Go, James Ladyman and Don Ross argued that analytic metaphysics should be dismissed and replaced with a naturalized metaphysics. In this paper, I critically discuss the arguments proposed in the book in order to determine whether this critique of analytic metaphysics is successful. In particular, Ladyman and Ross elaborate on three main points: the role of intuitions and the ensuing misunderstanding of science, the demarcation of science from (...)

    Deflazionismo.Andrea Strollo - 2012 - Aphex 6:on line article..
    Che cos'è la verità? A questa domanda le teorie deflazioniste rispondono in modo sorprendente: niente, o quasi. Secondo il deflazionismo la verità, come proprietà, semplicemente non esiste o è priva di qualsiasi sostanza. In questo contributo presenterò tale posizione offrendo un breve resoconto critico dell'evoluzione della proposta e una disamina delle sue tesi centrali.

    Metaphysics as Logic.Andrea Strollo - 2018 - Rivista di Estetica 69:7-20.
    Philosophy, and analytic metaphysics in particular, is usually described as an armchair discipline, and exactly for such an armchair methodology it has been the target of ferocious criticisms. In this paper, I argue that the theoretical right to conduct metaphysics from the armchair can be defended understanding metaphysics as a form of Logic (broadly understood as including applied logics, philosophical logics and, especially, philosophy of logic). So characterized, the typical practice of metaphysics is not more problematic than the armchair methodology (...)

  20. Subtle Truths. A formal investigation into Deflationism and Conservativeness.Andrea Strollo - 2010 - Dissertation, University of Torino - Italy
    At the end of the nineties some authors (Leon Horsten, Stewart Shapiro and Jeffrey Ketland) worked out a fairly technical argument against deflationary theories of truth. In a nutshell, deflationism, it was argued, is committed to conservativeness by the the claim that truth is not a substantial notion, a conservative theory (under the light of certain logico-mathematical facts) can not be an adequate theory of truth, therefore deflationism is an inadequate theory of truth. Beside the apparent simplicity of this argument, (...)
