    Modalities and Multimodalities.Walter Alexandre Carnielli, Claudio Pizzi & Juliana Bueno-Soler - 2008 - Dordrecht, Netherland: Springer.
    In the last two decades modal logic has undergone an explosive growth, to thepointthatacompletebibliographyofthisbranchoflogic,supposingthat someone were capable to compile it, would?ll itself a ponderous volume. What is impressive in the growth of modal logic has not been so much the quick accumulation of results but the richness of its thematic dev- opments. In the 1960s, when Kripke semantics gave new credibility to the logic of modalities? which was already known and appreciated in the Ancient and Medieval times? no one could (...)

    Strong Boethius' Thesis and Consequential Implication.Claudio Pizzi & Timothy Williamson - 1997 - Journal of Philosophical Logic 26 (5):569-588.
    The paper studies the relation between systems of modal logic and systems of consequential implication, a non-material form of implication satisfying "Aristotle's Thesis" (p does not imply not p) and "Weak Boethius' Thesis" (if p implies q, then p does not imply not q). Definitions are given of consequential implication in terms of modal operators and of modal operators in terms of consequential implication. The modal equivalent of "Strong Boethius' Thesis" (that p implies q implies that p does not imply (...)

    Necessity and Relative Contingency.Claudio Pizzi - 2007 - Studia Logica 85 (3):395-410.
    The paper introduces a contingential language extended with a propositional constant τ axiomatized in a system named KΔτ , which receives a semantical analysis via relational models. A definition of the necessity operator in terms of Δ and τ allows proving (i) that KΔτ is equivalent to a modal system named K□τ (ii) that both KΔτ and K□τ are tableau-decidable and complete with respect to the defined relational semantics (iii) that the modal τ -free fragment of KΔτ is exactly the (...)

    Conditional Excluded Middle in Systems of Consequential Implication.Claudio Pizzi & Timothy Williamson - 2005 - Journal of Philosophical Logic 34 (4):333-362.
    It is natural to ask under what conditions negating a conditional is equivalent to negating its consequent. Given a bivalent background logic, this is equivalent to asking about the conjunction of Conditional Excluded Middle and Weak Boethius' Thesis. In the system CI.0 of consequential implication, which is intertranslatable with the modal logic KT, WBT is a theorem, so it is natural to ask which instances of CEM are derivable. We also investigate the systems CIw and CI of consequential implication, corresponding (...)

    Generalization and Composition of Modal Squares of Oppositions.Claudio Pizzi - 2016 - Logica Universalis 10 (2-3):313-325.
    The first part of the paper aims at showing that the notion of an Aristotelian square may be seen as a special case of a variety of different more general notions: the one of a subAristotelian square, the one of a semiAristotelian square, the one of an Aristotelian cube, which is a construction made up of six semiAristotelian squares, two of which are Aristotelian. Furthermore, if the standard Aristotelian square is seen as a special ordered 4-tuple of formulas, there are (...)

    Two Kinds of Consequential Implication.Claudio Pizzi - 2018 - Studia Logica 106 (3):453-480.
    The first section of the paper establishes the minimal properties of so-called consequential implication and shows that they are satisfied by at least two different operators of decreasing strength and \). Only the former has been analyzed in recent literature, so the paper focuses essentially on the latter. Both operators may be axiomatized in systems which are shown to be translatable into standard systems of normal modal logic. The central result of the paper is that the minimal consequential system for (...)

    Aristotle’s Cubes and Consequential Implication.Claudio Pizzi - 2008 - Logica Universalis 2 (1):143-153.
    . It is shown that the properties of so-called consequential implication allow to construct more than one aristotelian square relating implicative sentences of the consequential kind. As a result, if an aristotelian cube is an object consisting of two distinct aristotelian squares and four distinct “semiaristotelian” squares sharing corner edges, it is shown that there is a plurality of such cubes, which may also result from the composition of cubes of lower complexity.

    MODEL-BASED REASONING IN SCIENCE AND TECHNOLOGY.Lorenzo Magnani, Walter Carnielli & Claudio Pizzi (eds.) - 2010 - Springer.
    This volume is based on the papers presented at the international conference Model-Based Reasoning in Science and Technology (MBR09_BRAZIL), held at the University of Campinas (UNICAMP), Campinas, Brazil, December 2009. The presentations given at the conference explored how scientific cognition, but several other kinds as well, use models, abduction, and explanatory reasoning to produce important or creative changes in theories and concepts. Some speakers addressed the problem of model-based reasoning in technology, and stressed the issue of science and technological innovation. (...)

    Relative Contingency and Bimodality.Claudio Pizzi - 2013 - Logica Universalis 7 (1):113-123.
    In the first part of the paper it is proved that there exists a one–one mapping between a minimal contingential logic extended with a suitable axiom for a propositional constant τ, named KΔτw, and a logic of necessity ${K\square \tau{w}}$ whose language contains ${\square}$ and τ. The form of the proposed translation aims at giving a solution to a problem which was left open in a preceding paper. It is then shown that the presence of τ in the language of (...)

    Possibility and Dyadic Contingency.Claudio E. A. Pizzi - 2022 - Journal of Logic, Language and Information 31 (3):451-463.
    The paper aims at developing the idea that the standard operator of noncontingency, usually symbolized by Δ, is a special case of a more general operator of dyadic noncontingency Δ(−, −). Such a notion may be modally defined in different ways. The one examined in the paper is __Δ__(B, A) = df ◊B ∧ (A ⥽ B ∨ A ⥽ ¬B), where ⥽ stands for strict implication. The operator of dyadic contingency __∇__(B, A) is defined as the negation of __Δ__(B, (...)

    Contenability and the Logic of Consequential Implication.Claudio Pizzi - 2004 - Logic Journal of the IGPL 12 (6):561-579.
    The aim of the paper is to outline a treatment of cotenability inspired by a perspective which had strong roots in ancient logic since Chrysippus and was partially recovered in the XX Century by E. Nelson and the exponents of so-called connexive logic. Consequential implication is a modal reinterpretation of connexive implication which permits a simple reconstruction of Aristotle's square of conditionals, in which proper place is given not only to ordinary cotenability between A and B, represented by ¬, but (...)

    The present article is devoted to a logical inquiry on the notions of permanence and termination, which play a central role in many areas of temporal reasoning. In the first part, we introduce a bimodal framework to represent these notions and provide a syntactic and semantic comparison with a monomodal framework representing the notion of future necessity. In the second part, we focus on the problem of defining synonymous logical systems over the two frameworks; as an example, we provide an (...)

    In the present work we provide a logical analysis of normatively determined and non-determined propositions. The normative status of these propositions depends on their relation with another proposition, here named reference proposition. Using a formal language that includes a monadic operator of obligation, we define eight dyadic operators that represent various notions of “being normatively (non-)determined”; then, we group them into two families, each forming an Aristotelian square of opposition. Finally, we show how the two resulting squares can be combined (...)

    Gestalt Effects in Counterfactual and Abductive Inference.Claudio Pizzi - 2006 - Logic Journal of the IGPL 14 (2):257-269.
    The paper begins by focusing the basic idea that Gestalt phenomena belong not only to the realm of perception but to the realm of inference. It is shown that Gestalt effects often occur both in counterfactual and in ampliative – i.e. inductive and abductive – reasoning. The main thesis of the paper is that the common feature of such forms of non-deductive reasoning is provided by a rational selection between incompatible conclusions, where rationality lies in the choice of the alternative (...)

    Chateaubriand on the Ambiguity of Counter-Factual Suppositions.Claudio Pizzi - 2004 - Manuscrito 27 (1):55-64.
    In Logical Forms Chateaubriand introduces a disambiguation technique that might turn out to be highly useful for analyzing important classes of sentences. In particular, he claims that this technique is relevant for analyzing counterfactual suppositions. In this paper I critically examine this claim and conclude that the ambiguity of counterfactuals is contextual rather than structural.
