    In this chapter, Ricardo Silvestre and Alan Herbert offer a reconstruction of the Gītā’s concept of God with a focus on the relationship between God and the world. They try to explain the claim that the Gītā is panentheistic. This is done with the help of some key notions of contemporary metaphysics (such as ontological dependence and fundamentality) along with the Indic notion of prakṛti, considered as a metaphysical primitive denoting the intimate relationship that exists between matter and co…Read more

    Pluralidade Religiosa e o Conceito de Deus
    Veritas – Revista de Filosofia da Pucrs 69 (1). 2024.
    Neste artigo, abordo algumas questões de ordem superior envolvendo o conceito de Deus que surgem dentro de um contexto pluralista: o problema da unidade conceitual, o problema da unicidade de extensão e o problema da homogeneidade/heterogeneidade. Minha proposta para resolver essas questões envolve uma teoria especial híbrida de conceitos, chamada de teoria de conceitos ideais. Argumento que, quando adicionada a uma visão pluralista de conceitos, e formalizada dentro de uma estrutura de mundos p…Read more

    Panentheism has seen a revival over the past two decades in the philosophical literature. This has partially triggered an interest in Indian models of God, which have traditionally been seen as panentheistic. On the other hand, panentheism has been often associated with panpsychism, an old ontological view that sees consciousness as fundamental and ubiquitous in the natural world and which has also enjoyed a renaissance in recent decades. Depending on where one places fundamentality (whether on …Read more

    In this paper I present a formalization of the theory of ideal concepts applied to the concept of God. It is done within a version of the Simplest Quantified Modal Logic (SQML) and attempts to solve three meta-problems related to the concept of God: the unicity of extension problem, the homogeneity/heterogeneity problem and the problem of conceptual unity.

    Vaiṣṇava concepts of god: philosophical perspectives (edited book)
    with Alan C. Herbert and Benedikt Paul Göcke
    Routledge. 2024.
    This book analyses the concepts of God in Vaisnavism, which is commonly referred to as one of the great Hindu monotheistic traditions. Addressing the question of what attributes God possesses according to particular textual sources and traditions in Vaisnavism, the book analyses Vaisnava traditions and texts in order to locate them within a global philosophical framework. The book is divided into two sections. The first one, God in Vaisnava Texts, deals with concepts of God found in the canonica…Read more

    In this article, I address some higher-order issues involving the concept of God that arise within a pluralistic context: the problem of conceptual unity, the problem of unicity of extension and the problem of homogeneity/heterogeneity. My proposal to solve these questions involves a special hybrid theory of concepts, called the theory of ideal concepts. I argue that when associated with a pluralistic vision of concepts, and formalized within a possible world structure, such theory provides a sa…Read more

    Meu propósito aqui é jogar alguma luz sobre duas perguntas: “Em que sentido a lógica éfilosófica?” e “O que é lógica filosófica?”. Tomo essas duas questões como sendo coextensivas: umaresposta à uma delas é também (ou pode ser facilmente transformada em) uma resposta à outra.Tentarei trabalhar a partir de três perspectivas: uma perspectiva conceitual, uma descritiva e umaprescritiva. Sendo mais específico, tentarei responder às seguintes perguntas: (i) Em que sentido alógica pode ser tomada como…Read more

    The Logic of the Concept of God

    In this article, I present a defense of conceptual plausibility, understood as an epistemic way to qualify concepts that situates them between the merely possible and the actual. To show that there is such a thing as conceptual plausibility, I rely on what seems to lie at the heart of many uses of the phrase “plausible concept”: explanatory fruitfulness. To make an effective case for the claim that conceptual plausibility is of philosophical interest, I present an argument based on the debate ov…Read more

    On the Representation of the Concept of God
    Philosophia 50 (2): 731-755. 2022.
    While the failure of the so-called classical theory of concepts - according to which definitions are the proper way to characterize concepts - is a consensus, metaphysical philosophy of religion still deals with the concept of God in a predominantly definitional way. It thus seems fair to ask: Does this failure imply that a definitional characterization of the concept of God is equally untenable? The first purpose of this paper is to answer this question. I focus on the representational side of …Read more

    Sobre a Formalização Lógica de Mudança de Teorias e Anomalias Científicas
    ARGUMENTOS - Revista de Filosofia 1 (17): 72-91. 2017.
    Neste trabalho, é apresentada uma investigação do que poderia ser chamado de formalização lógica do processo de mudança de teorias devido a anomalias. Por anomalia entende-se um fato observado que faz parte do escopo explanatório de uma teoria, mas que vai de encontro à previsão da mesma. Uma abordagem clássica para restaurar o poder explicativo de uma teoria ameaçada por uma anomalia é a postulação de hipóteses novas e provisórias que, em conjunto com as demais hipótese…Read more

    This paper aims at examining the issue of the role of supreme being theology in non-Abrahamic traditions. According to the dominant view in contemporary philosophy of religion, the philo-sophical project of inferring divine properties from the concept of God as a maximally perfect being, usually called supreme being theology, is an exclusivity of the Abrahamic traditions. In attempting to question this view, I investigate the developments of two key-concepts of Vedāntatradition –the concepts of …Read more

    On The Logical Formalization of Ansem's Ontological Argument
    Revista Brasileira de Filosofia da Religião 2 (1). 2015.
    he general theme of this paper is the issue of formalization in philosophy; in a more specific way, it deals with the issue of formalization of arguments in analytic philosophy of religion. One argument in particular – Anselm’s Proslogion II ontological argument – and one specific attempt to formalize it – Robert Adams’ formalization found in his paper “The Logical Structure of Anselm’s Arguments”, published in The Philosophical Review in 1971 – are taken as study cases. The purpose of the paper…Read more

    Is it possible to combine different logics into a coherent system with the goal of applying it to specific problems so that it sheds some light on foundational aspects of those logics? These are two of the most basic issues of combining logics. Paranormal modal logic is a combination of paraconsistent logic and modal logic. In this paper, I propose two further combinatory developments, focusing on each one of these two issues. On the foundational side, I combine paranormal modal logic with norma…Read more

    A Formal-Logical Approach to the Concept of God
    Manuscrito. Revista Internacional de Filosofia 44 (4): 224-260. 2021.
    In this paper I try to answer four basic questions: (1) How the concept of God is to be represented? (2) Are there any logical principles governing it? (3) If so, what kind of logic lies behind them? (4) Can there be a logic of the concept of God? I address them by presenting a formal-logical account to the concept of God. I take it as a methodological desideratum that this should be done within the simplest existing logical formalism. I start with first-order logic (FOL) with identity, and th…Read more

    A Estrutura do Yoga na Bhagavad-Gita
    Numen 1 (20): 28-46. 2017.
    O objetivo deste artigo é analisar o conceito de yoga da Bhagavad-gītā. Cinco concepções de yoga encontradas no texto são descritas: yoga enquanto disciplina ou prática, yoga enquanto disciplina qualificada, yoga enquanto estado mental de equanimidade e renúncia, yoga enquanto estado de união e yoga enquanto poder místico. As relações existentes entre essas concepções são explicitadas e o que podemos chamar de a estrutura do yoga na Bhagavad-gītā é pormenorizada.

    Ao mesmo tempo que o malogro da assim chamada teoria clássica dos conceitos - de acordo com a qual definições são a maneira apropriada de caracterizar conceitos - é um consenso, a filosofia metafísica da religião parece ainda lidar com o conceito de Deus de forma predominantemente definicional. Podemos então nos perguntar: Seria esse malogro suficiente para inviabilizar uma caracterização definicional do conceito de Deus? Meu propósito central neste artigo é responder essa pergunta. Adoto uma ên…Read more
  • Philosophical Logic = Philosophy + Logic?
    In J.-Y. Beziau, J.-P. Desclés, A. Moktefi & A. Pascau (eds.), Logic-in-Question (Workshop at the Sorbonne 2011-2019). pp. 299-327. 2021.
    My purpose in this paper is to shed some light on two questions: In what sense is logic philosophical? And what is philosophical logic? I take these two questions as co-extensive: an answer to one of them is also (or can easily be converted into) an answer to the other. I approach the problem from three perspectives: a conceptual, a descriptive and a prescriptive perspective. In other words, I try to answer the following questions: (i) In what sense can logic be taken as philosophical? (ii) In w…Read more

    Paraconsistent Logic as Model Building
    South American Journal of Logic 1 (4): 195-217. 2018.
    The terms “model” and “model-building” have been used to characterize the field of formal philosophy, to evaluate philosophy’s and philosophical logic’s progress and to define philosophical logic itself. A model is an idealization, in the sense of being a deliberate simplification of something relatively complex in which several important aspects are left aside, but also in the sense of being a view too perfect or excellent, not found in reality, of this thing. Paraconsistent logic is a branch o…Read more

    This volume deals with the relation between faith and reason, and brings the latest developments of modern logic into the scene. Faith and rationality are two perennial key concepts in the history of ideas. Philosophers and theologians have struggled to bring into harmony these otherwise conflicting concepts. Despite the diversity of approaches about what rationality effectively means, logic remains the cannon of objective and rational thought. The chapters in this volume analyze several issues …Read more
