    Logics and Their Galaxies.Hilan Bensusan, Alexandre Costa-Leite & Edélcio De De Souza - 2015 - In Arnold Koslow & Arthur Buchsbaum (eds.), The Road to Universal Logic. Birkhauser. pp. 243-252.
    This article introduces some concepts that help exploring the ontological import of universal logic. It studies the notions of an antilogic and counterlogic associated to each logic and shows some of their properties. It presents the notion of galaxy, as the class of possible worlds compatible with a given logic.We explore some consequences of these developments.

    On a Paraconsistentization Functor in the Category of Consequence Structures.Edelcio G. De Souza, Alexandre Costa-Leite & Diogo H. B. Dias - 2016 - Journal of Applied Non-Classical Logics 26 (3):240-250.
    This paper is an attempt to solve the following problem: given a logic, how to turn it into a paraconsistent one? In other words, given a logic in which ex falso quodlibet holds, how to convert it into a logic not satisfying this principle? We use a framework provided by category theory in order to define a category of consequence structures. Then, we propose a functor to transform a logic not able to deal with contradictions into a paraconsistent one. Moreover, (...)

    Fusions of Modal Logics and Fitch’s Paradox.Alexandre Costa-Leite - 2006 - Croatian Journal of Philosophy 6 (2):281-290.
    This article shows that although Fitch’s paradox has been extremely widely studied, up to now no correct formalization of the problem has been proposed. The purpose of this article is to present the paradox front the viewpoint of combining logics. It is argued that the correct minimal logic to state the paradox is composed by a fusion of modal frames, and a fusion of modal languages and logics.

    Lógicas da justificação e quase-verdade.Alexandre Costa-Leite - 2014 - Principia: An International Journal of Epistemology 18 (2):175.
    Two kinds of justification logics are studied. Then, this article shows how the notion of quasi-truth can be defined in these systems.

    Implications and Limits of Sequences.Alexandre Costa-Leite & Edelcio G. de Souza - 2017 - Studia Humana 6 (1):18-24.
    This paper analyzes the problem of implication and attempts to characterize conditionals by a criterion of adequacy. A definition of implication based on the notion of limit of an infinite sequence is proposed.

    Perspectives on Universal Logic.Jean-Yves Béziau & Alexandre Costa-Leite (eds.) - 2007 - Milan, Italy: Polimetrica.
    Universal logic is to logic what universal algebra is to algebra. It is not a specific system of logic that would apply to everything but a general theory of all existing and possible logics. This new field has been slowly emerging through the new directions of research in logic of the past decades and the name was coined 15 years ago. In the Spring of 2005 was organized in Montreux, Switzerland, the First World Congress on Universal Logic. This exciting event (...)
