    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 (...)

    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 (...)

    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 (...)

    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 (...)

    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 (...)

    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 (...)

    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 (...)

    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 (...)

    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 (...)

    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.

    Los impactos demográficos del modelo agroexportador en Argentina.Fernando Ariel Manzano & Guillermo Ángel Velázquez - 2021 - Astrolabio: Nueva Época 26:44-77.
    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 (...)

They include syntactic and semantic approaches to modelling awareness and an alternative view from the multi-agent systems perspective where awareness is identified as the ability to perceive and understand actions of other agents.Velázquez-Quesada studies a logic of plausibility acknowledgement models used to interpret the notions of implicit and explicit beliefs. The models use the notion of a formula (...)

    Phenomenology of the Locked-In Syndrome: an Overview and Some Suggestions.Fernando Vidal - 2018 - Neuroethics 13 (2):119-143.
    There is no systematic knowledge about how individuals with Locked-in Syndrome experience their situation. A phenomenology of LIS, in the sense of a description of subjective experience as lived by the ill persons themselves, does not yet exist as an organized endeavor. The present article takes a step in that direction by reviewing various materials and making some suggestions. First-person narratives provide the most important sources, but very few have been discussed. LIS barely appears in bioethics and neuroethics. Research on (...)

    What makes neuroethics possible?Fernando Vidal - 2019 - History of the Human Sciences 32 (2):32-58.
    Since its emergence in the early 2000s, neuroethics has become a recognized, institutionalized and professionalized field. A central strategy for its successful development has been the claim that it must be an autonomous discipline, distinct in particular from bioethics. Such claim has been justified by the conviction, sustained since the 1990s by the capabilities attributed to neuroimaging technologies, that somehow ‘the mind is the brain’, that the brain sciences can illuminate the full range of human experience and behavior, and that (...)

    Science in film, and usual equivalents such asscience on filmorscience on screen, refer to the cinematographic representation, staging, and enactment of actors, information, and processes involved in any aspect or dimension of science and its history. Of course, boundaries are blurry, and films shot as research tools or documentation also display science on screen. Nonetheless, they generally count asscientific film, andscience inandon filmorscreentend to designate productions whose purpose is entertainment and education.

    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 (...)

    La place de la psychologie dans l’ordre des sciences.Fernando Vidal - 1994 - Revue de Synthèse 115 (3-4):327-353.
    L’histoire de la psychologie en tant que discipline autonome comporte non seulement des développements méthodologiques et institutionnels, mais aussi l’élaboration du concept même de psychologie et des représentations de sa place dans l’ordre des sciences. Si de telles représentations ne détenninent pas la constitution du champ professionnel ou la pratique concrète du psychologue, elles n’en expriment pas moins des idéaux épistémologiques et reflètent les changements qui s’opèrent au sein de la discipline. Nous donnerons d’abord une vue générale de la position (...)

    Accuracy, Authenticity, Fidelity: Aesthetic Realism, the “Deficit Model,” and the Public Understanding of Science.Fernando Vidal - 2018 - Science in Context 31 (1):129-153.
    Argument“Deficit model” designates an outlook on the public understanding and communication of science that emphasizes scientific illiteracy and the need to educate the public. Though criticized, it is still widespread, especially among scientists. Its persistence is due not only to factors ranging from scientists’ training to policy design, but also to the continuance of realism as an aesthetic criterion. This article examines the link between realism and the deficit model through discussions of neurology and psychiatry in fiction film, as well (...)

    From the classic Frankenstein of 1931 to Matrix, which offers a version of the philosophical fable of the brain in a vat and on to Self/less, in which the consciousness of a dying tycoon is transferred to a younger man’s body, cinema has variously explored the relationship between personhood and the body by means of fictions concerning the brain and its contents.1 From the crude disembodied brains of 1950s B-movies to the neuroimaging visuals of 21st-century cyberpunk, these films localize individuality (...)

    The Beach and the Labyrinth: Experimental Urban Landscapes of the Human.Fernando Vidal - unknown
    In Dark City, people live in a city that is constantly in the dark. The city is in fact a laboratory constructed by a race of Strangers who live below the urban surface to do experiments aimed at discovering what makes human beings human. The Strangers will survive only by becoming like them. To find out what humanity is, but assuming it is essentially related to memory, every day they paralyze all human activity, extract memories from individuals, mix them, and (...)
