  1. Inference and update.Fernando Raymundo Velázquez-Quesada - 2009 - Synthese 169 (2):283-300.
    We look at two fundamental logical processes, often intertwined in planning and problem solving: inference and update. Inference is an internal process with which we uncover what is implicit in the information we already have. Update, on the other hand, is produced by external communication, usually in the form of announcements and in general in the form of observations, giving us information that might not have been available (even implicitly) before. Both processes have received attention from the logic community, usually (...)

  2. The dynamics of awareness.Fernando R. Velázquez-Quesada & Johan van Benthem - 2010 - Synthese 177 (S1):5 - 27.
    Classical epistemic logic describes implicit knowledge of agents about facts and knowledge of other agents based on semantic information. The latter is produced by acts of observation or communication that are described well by dynamic epistemic logics. What these logics do not describe, however, is how significant information is also produced by acts of inference— and key axioms of the system merely postulate "deductive closure". In this paper, we take the view that all information is produced by acts, and hence (...)

    Dynamic Epistemic Logic for Implicit and Explicit Beliefs.Fernando R. Velázquez-Quesada - 2014 - Journal of Logic, Language and Information 23 (2):107-140.
    Epistemic logic with its possible worlds semantic model is a powerful framework that allows us to represent an agent’s information not only about propositional facts, but also about her own information. Nevertheless, agents represented in this framework are logically omniscient: their information is closed under logical consequence. This property, useful in some applications, is an unrealistic idealisation in some others. Many proposals to solve this problem focus on weakening the properties of the agent’s information, but some authors have argued that (...)

    An epistemic and dynamic approach to abductive reasoning: Abductive problem and abductive solution.Fernando R. Velázquez-Quesada, Fernando Soler-Toscano & Ángel Nepomuceno-Fernández - 2013 - Journal of Applied Logic 11 (4):505-522.

    Reasoning Processes as Epistemic Dynamics.Fernando R. Velázquez-Quesada - 2015 - Axiomathes 25 (1):41-60.
    This work proposes an understanding of deductive, default and abductive reasoning as different instances of the same phenomenon: epistemic dynamics. It discusses the main intuitions behind each one of these reasoning processes, and suggest how they can be understood as different epistemic actions that modify an agent’s knowledge and/or beliefs in a different way, making formal the discussion with the use of the dynamic epistemic logic framework. The ideas in this paper put the studied processes under the same umbrella, thus (...)

    Bisimulations for Knowing How Logics.Raul Fervari, Fernando R. Velázquez-Quesada & Yanjing Wang - forthcoming - Review of Symbolic Logic:1-37.
    As a new type of epistemic logics, the logics of knowing how capture the high-level epistemic reasoning about the knowledge of various plans to achieve certain goals. Existing work on these logics focuses on axiomatizations; this paper makes the first study of their model theoretical properties. It does so by introducing suitable notions of bisimulation for a family of five knowing how logics based on different notions of plans. As an application, we study and compare the expressive power of these (...)

    Syntactic awareness in logical dynamics.Davide Grossi & Fernando R. Velázquez-Quesada - 2015 - Synthese 192 (12):4071-4105.
    The paper develops an interface between syntax-based logical models of awareness and dynamic epistemic logic. The framework is shown to be able to accommodate a variety of notions of awareness and knowledge, as well as their dynamics. This, it is argued, offers a natural formal environment for the analysis of epistemic phenomena typical of multi-agent information exchange, such as how agents become aware of relevant details, how they perform inferences and how they share their information within a group. Technically, the (...)

    Cautious Distributed Belief.John Lindqvist, Fernando R. Velázquez-Quesada & Thomas Ågotnes - 2023 - In Carlos Areces & Diana Costa (eds.), Dynamic Logic. New Trends and Applications: 4th International Workshop, DaLí 2022, Haifa, Israel, July 31–August 1, 2022, Revised Selected Papers. Springer Verlag. pp. 106-124.
    This paper introduces and studies a notion of cautious distributed belief. Different from the standard distributed belief, the cautious distributed belief of a group is inconsistent only when all group members are individually inconsistent. The paper presents basic results about cautious distributed belief, investigates whether it preserves properties of individual belief, and compares it with standard distributed belief. Although both notions are equivalent in the class of reflexive models, this is not the case in general. While we argue that an (...)

    Generation and Selection of Abductive Explanations for Non-Omniscient Agents.Fernando Soler-Toscano & Fernando R. Velázquez-Quesada - 2014 - Journal of Logic, Language and Information 23 (2):141-168.
    Among the non-monotonic reasoning processes, abduction is one of the most important. Usually described as the process of looking for explanations, it has been recognized as one of the most commonly used in our daily activities. Still, the traditional definitions of an abductive problem and an abductive solution mention only theories and formulas, leaving agency out of the picture. Our work proposes a study of abductive reasoning from an epistemic and dynamic perspective. In the first part we explore syntactic definitions (...)

    Non-strict Interventionism: The Case Of Right-Nested Counterfactuals.Katrin Schulz, Sonja Smets, Fernando R. Velázquez-Quesada & Kaibo Xie - 2022 - Journal of Logic, Language and Information 31 (2):235-260.
    The paper focuses on a recent challenge brought forward against the interventionist approach to the meaning of counterfactual conditionals. According to this objection, interventionism cannot account for the interpretation of right-nested counterfactuals, the problem being its strict interventionism. We will report on the results of an empirical study supporting the objection. Furthermore, we will extend the well-known logic of intervention with a new operator expressing an alternative notion of intervention that does away with strict interventionism. This new notion of intervention (...)

    Beliefs supported by binary arguments.Chenwei Shi, Sonja Smets & Fernando R. Velázquez-Quesada - 2018 - Journal of Applied Non-Classical Logics 28 (2-3):165-188.
    In this paper, we explore the relation between an agent’s doxastic attitude and her arguments in support of a given claim. Our main contribution is the design of a logical setting that allows us reason about binary arguments which are either in favour or against a certain claim. This is a setting in which arguments and propositions are the basic building blocks so that the concept of argument-based belief emerges in a straightforward way. We work against the background of Dung’s (...)

    Logic of Justified Beliefs Based on Argumentation.Chenwei Shi, Sonja Smets & Fernando R. Velázquez-Quesada - 2021 - Erkenntnis 88 (3):1207-1243.
    This manuscript presents a topological argumentation framework for modelling notions of evidence-based (i.e., justified) belief. Our framework relies on so-called topological evidence models to represent the pieces of evidence that an agent has at her disposal, and it uses abstract argumentation theory to select the pieces of evidence that the agent will use to define her beliefs. The tools from abstract argumentation theory allow us to model agents who make decisions in the presence of contradictory information. Thanks to this, it (...)

    A Closeness- and Priority-Based Logical Study of Social Network Creation.Sonja Smets & Fernando R. Velázquez-Quesada - 2020 - Journal of Logic, Language and Information 29 (1):21-51.
    This paper is part of an on-going programme on the study of the logical aspects of social network formation. It recalls the so-called social network model, discussing the properties of a notion of closeness between agents ; then introduces an extended social network model in which different agents might assign different values to different traits, discussing the properties of the notion of weighted closeness that arises. These notions are used to define social network creation operations by means of a threshold (...)

    First Steps in Updating Knowing How.Carlos Areces, Raul Fervari, Andrés R. Saravia & Fernando R. Velázquez-Quesada - 2023 - In Carlos Areces & Diana Costa (eds.), Dynamic Logic. New Trends and Applications: 4th International Workshop, DaLí 2022, Haifa, Israel, July 31–August 1, 2022, Revised Selected Papers. Springer Verlag. pp. 1-16.
    We investigate dynamic operations acting over a knowing how logic. Our approach makes use of a recently introduced semantics for the knowing how operator, based on an indistinguishability relation between plans. This semantics is arguably closer to the standard presentation of knowing that modalities in classic epistemic logic. Here, we discuss how the semantics enables us to define dynamic modalities representing different ways in which an agent can learn how to achieve a goal. In this regard, we study two types (...)

    Minimal abductive solutions with explicit justification.Rodrigo Medina-Vega, Francisco Hernández-Quiroz & Fernando R. Velázquez-Quesada - 2021 - Logic Journal of the IGPL 29 (4):483-502.
    Abductive problems and their solutions are presented by means of justification logic. We introduce additional meta-constructions in order to generate and compare different solutions to the same abductive problem. Our approach has three advantages: (i) it makes structurally explicit the solution to an abductive problem (as it has a syntactic nature); (ii) it gives a precise meaning to the notion of evidence; (iii) it provides clear definitions and procedures for the comparison of solutions that can be adapted to different needs.

    Tras la llegada de los conquistadores españoles y durante los dos siglos del reinado de su monopolio, no se permitió el ingreso de extranjeros y la población permaneció distribuida en las regiones, en proporciones casi inversas a las actuales. Con la caída del régimen español y los avances del monopolio inglés, comenzó a desplazarse el centro territorial argentino desde el Noroeste hacia el Litoral y a producirse variaciones en la dinámica demográfica. El establecimiento del modelo agroexportador produjo una afluencia excepcional (...)

    Brainhood, anthropological figure of modernity.Fernando Vidal - 2009 - History of the Human Sciences 22 (1):5-36.
    If personhood is the quality or condition of being an individual person, brainhood could name the quality or condition of being a brain. This ontological quality would define the `cerebral subject' that has, at least in industrialized and highly medicalized societies, gained numerous social inscriptions since the mid-20th century. This article explores the historical development of brainhood. It suggests that the brain is necessarily the location of the `modern self', and that, consequently, the cerebral subject is the anthropological figure inherent (...)

    Un análisis de la noción de filosofía en Heidegger y en Deleuze nos permite comprobar cómo ambos se ven llevados a un planteamiento estético, a una concepción poética del lenguaje o de la creatividad, para caracterizar a la filosofía misma. La distancia entre ambos reside, no obstante, en la insatisfacción que inevitablemente sufren las esperanzas de Heidegger al depositarlas en lo poético, mientras que Deleuze equipara el quehacer filosófico y el estético al consistir ambos en producción de sentido. An analysis (...)

Such appeals to the moral authority of nature are still very much with us today, as heated debates over genetically modified organisms and human cloning testify. _The Moral Authority of Nature_ offers a wide-ranging account of how people have used nature to think about what counts as good, beautiful, just, or valuable.

    Conservativity in generalized quantifiers is linked to presupposition filtering, under a propositions-as-types analysis extended with dependent quantifiers. That analysis is underpinned by modeltheoretically interpretable proofs which inhabit propositions they prove, thereby providing objects for quantification and hooks for anaphora.

    When is humanitarian intervention legitimate and how should such interventions be conducted? This article sets out eight liberal principles that underlie humanitarian intervention, some of them abstract principles of international ethics and others more concrete principles that apply specifically to humanitarian intervention. It argues that whilst these principles do not determine the legitimacy of particular interventions, they should ?incline? our judgments towards approval or disapproval. The basic principles include the liberal idea that governments are the mere agents of the people, (...)

    Where Does the Knowledge Argument Go Wrong?Fernando Rudy Hiller - 2023 - Análisis Filosófico 43 (1):131-156.
    In his well-known Knowledge Argument (KA) Frank Jackson attempted to show that physicalism is false by offering a case that allegedly showed that a complete physicalist description of the world leaves something crucial out, namely the phenomenal qualities of experience. Eventually Jackson himself retracted and claimed that the interesting task is to explain where and why intuition-pumping arguments against physicalism such as the KA go wrong. This is exactly the task that occupies this paper: to discuss and criticize three of (...)
