    Weak Necessity on Weak Kleene Matrices.Fabrice Correia - 1998 - In Marcus Kracht, Maarten de Rijke, Heinrich Wansing & Michael Zakharyaschev (eds.), Advances in Modal Logic. CSLI Publications. pp. 73-90.
    A possible world semantics for standard modal languages is presented, where the valuation functions are allowed to be partial, the truth--functional connectives are interpreted according to weak Kleene matrices, and the necessity operator is given a "weak" interpretation. Completeness and incompleteness results for some (axiomatic) systems are then established. Extensions of these modal logics in which figure "statability" operators are also examined.

    Filozofia i logika intuicjonizmu.Marlena Fila - 2015 - Semina Scientiarum 14:35-48.
    At the end of the 19th century in the fundamentals of mathematics appeared a crisis. It was caused by the paradoxes found in Cantor’s set theory. One of the ideas a resolving the crisis was intuitionism – one of the constructivist trends in the philosophy of mathematics. Its creator was Brouwer, the main representative was Heyting. In this paper described will be attempt to construct a suitable logic for philosophical intuitionism theses. In second paragraph Heyting system will be present – (...)

    Au commencement était la métaphore: Une intuition précoce de Nietzsche sur la primauté de la métaphore comme matrice cognitive.Laurent Lamy - 2015 - Kriterion: Journal of Philosophy 56 (132):521-540.
    RÉSUMÉ Cette étude met en perspective le précédent constitué par les travaux précoces du jeune Nietzsche où ce dernier fait valoir la force structurante de la métaphore comme matrice des facultés cognitives. Nous offrons d’abord une brève esquisse des postulats et des acquis des grammaires cognitives associées aux travaux d’Eleanor Rosch, ensuite de George Lakoff et Mark Johnson, ainsi qu’à la notion d’inscription corporelle de l’esprit développée par Francesco Varela. Cet exercice sert de propédeutique à une série de lectures tangentes (...)

  5. Peirce's Truth-functional Analysis and the Origin of the Truth Table.Irving H. Anellis - 2012 - History and Philosophy of Logic 33 (1):87 - 97.
    We explore the technical details and historical evolution of Charles Peirce's articulation of a truth table in 1893, against the background of his investigation into the truth-functional analysis of propositions involving implication. In 1997, John Shosky discovered, on the verso of a page of the typed transcript of Bertrand Russell's 1912 lecture on ?The Philosophy of Logical Atomism? truth table matrices. The matrix for negation is Russell's, alongside of which is the matrix for material implication in (...)

    Non-deterministic Conditionals and Transparent Truth.Federico Pailos & Lucas Rosenblatt - 2015 - Studia Logica 103 (3):579-598.
    Theories where truth is a naive concept fall under the following dilemma: either the theory is subject to Curry’s Paradox, which engenders triviality, or the theory is not trivial but the resulting conditional is too weak. In this paper we explore a number of theories which arguably do not fall under this dilemma. In these theories the conditional is characterized in terms of non-deterministic matrices. These non-deterministic theories are similar to infinitely-valued Łukasiewicz logic in that they are consistent (...)

    On the logic that preserves degrees of truth associated to involutive Stone algebras.Liliana M. Cantú & Martín Figallo - 2020 - Logic Journal of the IGPL 28 (5):1000-1020.
    Involutive Stone algebras were introduced by R. Cignoli and M. Sagastume in connection to the theory of $n$-valued Łukasiewicz–Moisil algebras. In this work we focus on the logic that preserves degrees of truth associated to S-algebras named Six. This follows a very general pattern that can be considered for any class of truth structure endowed with an ordering relation, and which intends to exploit many-valuedness focusing on the notion of inference that results from preserving lower bounds of (...) values, and hence not only preserving the value $1$. Among other things, we prove that Six is a many-valued logic that can be determined by a finite number of matrices. Besides, we show that Six is a paraconsistent logic. Moreover, we prove that it is a genuine Logic of Formal Inconsistency with a consistency operator that can be defined in terms of the original set of connectives. Finally, we study the proof theory of Six providing a Gentzen calculus for it, which is sound and complete with respect to the logic. (shrink)

    A Routley-Meyer semantics for truth-preserving and well-determined Lukasiewicz 3-valued logics.G. Robles & J. M. Mendez - 2014 - Logic Journal of the IGPL 22 (1):1-23.
    Łukasiewicz 3-valued logic Ł3 is often understood as the set of all valid formulas according to Łukasiewicz 3-valued matrices MŁ3. Following Wojcicki, in addition, we shall consider two alternative interpretations of Ł3: ‘truth-preserving’ Ł3a and ‘well-determined’ Ł3b defined by two different consequence relations on the 3-valued matrices MŁ3. The aim of this article is to provide a Routley–Meyer ternary semantics for each one of these three versions of Łukasiewicz 3-valued logic: Ł3, Ł3a and Ł3b.

    The aim of this article is to explore the class of intermediate logics between the truth-preserving Lukasiewicz logic L and its degree-preserving companion L<⁠. From a syntactical point of view, we introduce some families of inference rules (that generalize the explosion rule) that are admissible in L< and derivable in L and we characterize the corresponding intermediate logics. From a semantical point of view, we first consider the family of logics characterized by matrices defined by lattice filters in (...)

    Two Decision Procedures for da Costa’s $$C_n$$ C n Logics Based on Restricted Nmatrix Semantics.Marcelo E. Coniglio & Guilherme V. Toledo - 2022 - Studia Logica 110 (3):601-642.
    Despite being fairly powerful, finite non-deterministic matrices are unable to characterize some logics of formal inconsistency, such as those found between mbCcl and Cila. In order to overcome this limitation, we propose here restricted non-deterministic matrices (in short, RNmatrices), which are non-deterministic algebras together with a subset of the set of valuations. This allows us to characterize not only mbCcl and Cila (which is equivalent, up to language, to da Costa's logic C_1) but the whole hierarchy of da (...)

    Finite non-deterministic semantics for some modal systems.Marcelo E. Coniglio, Luis Fariñas del Cerro & Newton M. Peron - 2015 - Journal of Applied Non-Classical Logics 25 (1):20-45.
    Trying to overcome Dugundji’s result on uncharacterisability of modal logics by finite logical matrices, Kearns and Ivlev proposed, independently, a characterisation of some modal systems by means of four-valued multivalued truth-functions , as an alternative to Kripke semantics. This constitutes an antecedent of the non-deterministic matrices introduced by Avron and Lev . In this paper we propose a reconstruction of Kearns’s and Ivlev’s results in a uniform way, obtaining an extension to another modal systems. The first part (...)

    Matrix characterisation of the hierarchy FiCn of bivaluated logics.Víctor Fernández & Gabriela Eisenberg - 2024 - Journal of Applied Non-Classical Logics 35 (1):46-67.
    In this paper, we define the family FiCn:={FiCn}n∈ω of logics by means of semantics of bivaluations. This family is a variant of the family of paraconsistent bivaluated Ciun-logics, defined and studied by J. Ciuciura. We will show that every logic in FiCn can be alternatively defined by means of finite matrices. This result arises from the characterisation of the truth-values of the involved matrices (relative to each FiCn-logic) as being specific finite sequences of elements of the set (...)

  14. Doing the right things–trivalence in deontic action logic.Piotr Kulicki & Robert Trypuz - 2012 - Trivalent Logics and Their Applications.
    Trivalence is quite natural for deontic action logic, where actions are treated as good, neutral or bad.We present the ideas of trivalent deontic logic after J. Kalinowski and its realisation in a 3-valued logic of M. Fisher and two systems designed by the authors of the paper: a 4-valued logic inspired by N. Belnap’s logic of truth and information and a 3-valued logic based on nondeterministic matrices. Moreover, we combine Kalinowski’s idea of trivalence with deontic action logic based (...)

    Basic Four-Valued Systems of Cyclic Negations.Oleg Grigoriev & Dmitry Zaitsev - 2022 - Bulletin of the Section of Logic 51 (4):507-533.
    We consider an example of four valued semantics partially inspired by quantum computations and negation-like operations occurred therein. In particular we consider a representation of so called square root of negation within this four valued semantics as an operation which acts like a cycling negation. We define two variants of logical matrices performing different orders over the set of truth values. Purely formal logical result of our study consists in axiomatizing the logics of defined matrices as the (...)

  16. Logical Non-determinism as a Tool for Logical Modularity: An Introduction.Arnon Avron - unknown
    It is well known that every propositional logic which satisfies certain very natural conditions can be characterized semantically using a multi-valued matrix ([Los and Suszko, 1958; W´ ojcicki, 1988; Urquhart, 2001]). However, there are many important decidable logics whose characteristic matrices necessarily consist of an infinite number of truth values. In such a case it might be quite difficult to find any of these matrices, or to use one when it is found. Even in case a logic (...)

    Multi-valued Semantics: Why and How.Arnon Avron - 2009 - Studia Logica 92 (2):163-182.
    According to Suszko's Thesis,any multi-valued semantics for a logical system can be replaced by an equivalent bivalent one. Moreover: bivalent semantics for families of logics can frequently be developed in a modular way. On the other hand bivalent semantics usually lacks the crucial property of analycity, a property which is guaranteed for the semantics of multi-valued matrices. We show that one can get both modularity and analycity by using the semantic framework of multi-valued non-deterministic matrices. We further show (...)

  19. On Nilpotent Minimum logics defined by lattice filters and their paraconsistent non-falsity preserving companions.Joan Gispert, Francesc Esteva, Lluís Godo & Marcelo E. Coniglio - forthcoming - Logic Journal of the IGPL.
    Nilpotent Minimum logic (NML) is a substructural algebraizable logic that is a distinguished member of the family of systems of Mathematical Fuzzy logic, and at the same time it is the axiomatic extension with the prelinearity axiom of Nelson and Markov’s Constructive logic with strong negation. In this paper our main aim is to characterize and axiomatize paraconsistent variants of NML and its extensions defined by (sets of) logical matrices over linearly ordered NM-algebra with lattice filters as designated values, (...)

    Matrix logic.August Stern - 1988 - New York, N.Y., U.S.A.: Sole distributors for the U.S.A. and Canada, Elsevier.
    In this pioneering work, the author develops a fundamental formulation of logic in terms of theory of matrices and vector spaces. The discovery of matrix logic represents a landmark in the further formalization of logic. For the first time the power of direct mathematical computation is applied to the whole set of logic operations, allowing the derivation of both the classical and modal logics from the same formal base. The new formalism allows the author to enlarge the alphabet of (...)

    Vector logic allows counterfactual virtualization by the square root of NOT.Eduardo Mizraji - 2021 - Logic Journal of the IGPL 29 (5):859-870.
    In this work, we investigate the representation of counterfactual conditionals using the vector logic, a matrix-vector formalism for logical functions and truth values. Inside this formalism, the counterfactuals can be transformed in complex matrices preprocessing an implication matrix with one of the square roots of NOT, a complex matrix. This mathematical approach puts in evidence the virtual character of the counterfactuals. This happens because this representation produces a valuation of a counterfactual that is the superposition of the two (...)

The thesis is deployed against the view, advanced by Hilary Putnam and by Richard Rorty, that we cannot exit the circle of words so as to secure any version of external realism. ;To establish the thesis, an intentionalist hermeneutics is developed: Due (...)

We study the subsystems of Classical Logic satisfying these requirements and assess the extent to which it is possible to characterise them by means of a single logical matrix. In addition, we semantically describe both of these companions to Classical Logic in (...)

    Combining Swap Structures: The Case of Paradefinite Ivlev-Like Modal Logics Based on $$FDE$$.Marcelo E. Coniglio - forthcoming - Studia Logica:1-52.
    The aim of this paper is to combine several Ivlev-like modal systems characterized by 4-valued non-deterministic matrices (Nmatrices) with $$\mathcal {IDM}4$$, a 4-valued expansion of Belnap–Dunn’s logic $$FDE$$ with an implication introduced by Pynko in 1999. In order to do this, we introduce a new methodology for combining logics which are characterized by means of swap structures, based on what we call superposition of snapshots. In particular, the combination of $$\mathcal {IDM}4$$ with $$Tm$$, the 4-valued Ivlev’s version of KT, (...)

    How can the reference of theoretical terms be stable over changes of theory? I defend an approach to this that does not depend on substantive metasemantic theories of reference. It relies on the idea that in contexts of use, terms may play a role in a theory that in turn points to a further (possibly unknown) theory. Empirical claims are claims about the nature of the further theories, and the falsification of these further theories is understood not as showing that (...)

    An Unexpected Boolean Connective.Sérgio Marcelino - 2022 - Logica Universalis 16 (1):85-103.
    We consider a 2-valued non-deterministic connective \({\wedge \!\!\!\!\!\vee }\) defined by the table resulting from the entry-wise union of the tables of conjunction and disjunction. Being half conjunction and half disjunction we named it _platypus_. The value of \({\wedge \!\!\!\!\!\vee }\) is not completely determined by the input, contrasting with usual notion of Boolean connective. We call non-deterministic Boolean connective any connective based on multi-functions over the Boolean set. In this way, non-determinism allows for an extended notion of truth-functional (...)

  39. Cut-free ordinary sequent calculi for logics having generalized finite-valued semantics.Arnon Avron, Jonathan Ben-Naim & Beata Konikowska - 2007 - Logica Universalis 1 (1):41-70.
    . The paper presents a method for transforming a given sound and complete n-sequent proof system into an equivalent sound and complete system of ordinary sequents. The method is applicable to a large, central class of (generalized) finite-valued logics with the language satisfying a certain minimal expressiveness condition. The expressiveness condition decrees that the truth-value of any formula φ must be identifiable by determining whether certain formulas uniformly constructed from φ have designated values or not. The transformation preserves the (...)

    Dual Equivalent Two-valued Under-determined and Over-determined Interpretations for Łukasiewicz's 3-valued Logic Ł3.Gemma Robles, Francisco Salto & José M. Méndez - 2013 - Journal of Philosophical Logic (2-3):1-30.
    Łukasiewicz three-valued logic Ł3 is often understood as the set of all 3-valued valid formulas according to Łukasiewicz’s 3-valued matrices. Following Wojcicki, in addition, we shall consider two alternative interpretations of Ł3: “well-determined” Ł3a and “truth-preserving” Ł3b defined by two different consequence relations on the 3-valued matrices. The aim of this paper is to provide (by using Dunn semantics) dual equivalent two-valued under-determined and over-determined interpretations for Ł3, Ł3a and Ł3b. The logic Ł3 is axiomatized as an (...)

    The algebra of propositions.H. B. Smith - 1936 - Philosophy of Science 3 (4):551-578.
    It is proposed in this paper to develop a method by which the most general problem of the algebra of propositions is solved. This problem is to construct all propositions whose truth is independent of the form of the variables. As might be expected this method will enable us to determine without the use of matrices the consistency and independence of propositions, except in the case of those fundamental properties, which taken together define consistency itself. In the discussion (...)

    Buridan's consequentia: consequence and inference within a token-based semantics.Catarina Dutilh Novaes - 2005 - History and Philosophy of Logic 26 (4):277-297.
    I examine the theory of consequentia of the medieval logician, John Buridan. Buridan advocates a strict commitment to what we now call proposition-tokens as the bearers of truth-value. The analysis of Buridan's theory shows that, within a token-based semantics, amendments to the usual notions of inference and consequence are made necessary, since pragmatic elements disrupt the semantic behaviour of propositions. In my reconstruction of Buridan's theory, I use some of the apparatus of modern two-dimensional semantics, such as two-dimensional (...) and the distinction between the context of formation and the context of evaluation of utterances.

    The Strong Version of a Sentential Logic.Ramon Jansana, Josep Maria Font & Hugo Albuquerque - 2017 - Studia Logica 105 (4):703-760.
    This paper explores a notion of “the strong version” of a sentential logic S, initially defined in terms of the notion of a Leibniz filter, and shown to coincide with the logic determined by the matrices of S whose filter is the least S-filter in the algebra of the matrix. The paper makes a general study of this notion, which appears to unify under an abstract framework the relationships between many pairs of logics in the literature. The paradigmatic examples (...)

    Creative Synthesis and Philosophic Method. [REVIEW]L. C. R. - 1972 - Review of Metaphysics 25 (4):754-755.
    As the title indicates, this most recent of Hartshorne's works blends doctrinal exposition with analyses of methodological issues. Each of the sixteen chapters can be read as an independent essay, although the entire work is intended as "an essay in systematic metaphysics." The paradox is resolved once we realize that Hartshorne does not separate substantive discussion and the examination of methodological principles--the text exemplifies the principles latent in "creative synthesis" as he understands it. Each chapter takes shape out of a (...)

    Left Variable Inclusion Logics Associated with Classical Logic.Francesco Paoli & Michele Pra Baldi - 2024 - Notre Dame Journal of Formal Logic 65 (4):457-480.
    Logics of significance have been proposed in an attempt to overcome the shortcomings of classical logic as a model of reasoning in the presence of nonsignificant (e.g., meaningless, ill-formed, unverifiable) sentences. Many-valued logicians have addressed this problem by introducing logics with infectious truth values. Cases in point are the weak Kleene logics B3 (paracomplete weak Kleene logic) and PWK (paraconsistent weak Kleene logic). Over time, it has become clear that the valid entailments of these significance logics obey variable inclusion (...)

    In lieu of an abstract, here is a brief excerpt of the content:Haiti Can't BreatheNéhémy Pierre-Dahomey (bio)Translated by David F. BellI'm not particularly familiar with recent politics in Haiti. Nor, as it were, with the contemporary history of the country. In some sense, the difference between recent politics and contemporary history is rather delicate. History would be the most profound social, political, and economic points of contention behind the daily lives of a population under siege. Not simply those talked about (...)

    Phylogenetic Inference and the Misplaced Premise of Substitution Rates.Kirk Fitzhugh - 2021 - Acta Biotheoretica 69 (4):799-819.
    Three competing ‘methods’ have been endorsed for inferring phylogenetic hypotheses: parsimony, likelihood, and Bayesianism. The latter two have been claimed superior because they take into account rates of sequence substitution. Can rates of substitution be justified on its own accord in inferences of explanatory hypotheses? Answering this question requires addressing four issues: (1) the aim of scientific inquiry, (2) the nature of why-questions, (3) explanatory hypotheses as answers to why-questions, and (4) acknowledging that neither parsimony, likelihood, nor Bayesianism are inferential (...)
