    Interpretation as a Form of Thermodynamic Work.Felipe A. Veloso - 2021 - Biosemiotics 14 (3):625-631.
    In this commentary I present five corollaries that follow the target article “How molecules became signs” by Terrence W. Deacon and also two outstanding questions the article rises. The corollaries revolve around the notion of interpretation as a form of thermodynamic work—specifically, non-expansion or “useful” work. This specific form of work, along with its path-dependent nature, may be critical for the fundamental understanding of semiotic processes, the subjective character of interpretation, and even the nature of viruses.

    Una novela hospitalaria: La cresta de Ilión, de Cristina Rivera-Garza.Felipe A. Ríos Baeza - 2019 - Valenciana 24:95-118.
    A partir del concepto de hospitalidad propuesto por el filósofo francés Jacques Derrida, este ensayo pretende definir los rasgos más significativos de La cresta de Ilión (Tusquets, 2002), de la escritora mexicana Cristina Rivera Garza; novela recientemente reeditada (Random House, 2018) y que resulta pieza fundamental de su narrativa, ya que desde allí se irradiarán muchos asuntos singulares para sus obras posteriores. Si en Nadie me verá llorar (1999), primera novela de Rivera Garza, buena parte de las acciones acontecían en (...)

    The Art-Cartography: The Work of Art as a Map of Intensity.Felipe A. Matti - 2023 - Eidos: Revista de Filosofía de la Universidad Del Norte 40:163-188.
    RESUMEN En este artículo se analiza la caracterización de la obra de arte como un mapa de intensidad que propone Gilles Deleuze en su ensayo intitulado Lo que dicen los niños, recogido en el libro Crítica y clínica. El aspecto cartográfico del arte se vincula con el concepto de desterritorialización y el Cuerpo sin Órganos que desarrolla el filósofo, junto con Félix Guattarí, en Mil Mesetas. Así, el arte-cartografía representa el devenir-mundo del sujeto que transita el Cuerpo sin Órganos y (...)

    Naturaleza y genio como símbolos en Kant: la interpretación simbólica de Gilles Deleuze de la Crítica del juicio.Felipe A. Matti - 2023 - Logos Revista de Filosofía 141 (141):85-202.
    En este trabajo se analizará la interpretación que hace Gilles Deleuze de la naturaleza y el genio como símbolos de la unidad suprasensible de las facultades en la Crítica del juicio. Deleuze propone que el juicio estético puro sería el proceso por el cual se alcanzaría la unidad de las facultades del sujeto trascendental: lo bello expresaría una “unidad suprasensible indeterminada” del sujeto del juicio de gusto. De este modo, aquí se indagará la factibilidad de la tesis deleuziana y se (...)

    Class of Exact Solutions for a Cosmological Model of Unified Gravitational and Quintessence Fields.Sergio A. Hojman & Felipe A. Asenjo - 2017 - Foundations of Physics 47 (7):887-896.
    A new approach to tackle Einstein equations for an isotropic and homogeneous Friedmann–Robertson–Walker Universe in the presence of a quintessence scalar field is devised. It provides a way to get a simple exact solution to these equations. This solution determines the quintessence potential uniquely and it differs from solutions which have been used to study inflation previously. It relays on a unification of geometry and dark matter implemented through the definition of a functional relation between the scale factor of the (...)

    A relação entre cibernética E metafisica E suas consequências na Vida social a partir da monadologia de G. W. Leibniz.Felipe A. De Luca - 2016 - Cadernos Espinosanos 34:229-250.
    É amplo o estudo sobre Leibniz hoje: conhecemo-lo como o filósofo metafísico de tendências religiosas, como opositor de Descartes, como vitalista, matemático etc.; mas a pergunta que orienta nossa pesquisa busca deslindar novos horizontes: é possível encontrar elementos em sua metafísica que nos permitam pensar o cenário social contemporâneo? A partir das ferramentas conceituais criadas pelo filósofo pensamos que a resposta seja positiva.

    Our goal was to explore self‐care practices among men who have sex with men in the context of Mpox in Brazil. This study used qualitative research methods, including interviews and thematic analysis, to collect and analyze data from male participants across the Brazilian territory. The narratives unveil men's perspectives on self‐care, risk reduction, and health beliefs during the Mpox pandemic. Our findings highlight a multifaceted approach to self‐care among men, encompassing hygiene, physical contact management, mask usage, skin lesion vigilance, and (...)

    Validades Existenciais e Enigmas Relacionados.Paulo A. S. Veloso, Luiz Carlos Pereira & Edward H. Haeusler - 2009 - Dois Pontos 6 (2).
    A lógica não contém teoremas puramente existenciais: as únicas sentenças existenciaisválidas são aquelas com análogas universais válidas. Aqui, mostramos que istorealmente é assim quando corretamente interpretado: toda validade ex- istencial possuiuma análoga universal simples, que também é válida. Também caracterizamos validadesuniversais e existenciais em termos de tautologias.

    Joint attention without recursive mindreading: On the role of second-person engagement.Felipe León - 2021 - Philosophical Psychology 34 (4):550-580.
    On a widely held characterization, triadic joint attention is the capacity to perceptually attend to an object or event together with another subject. In the last four decades, research in developmental psychology has provided increasing evidence of the crucial role that this capacity plays in socio-cognitive development, early language acquisition, and the development of perspective-taking. Yet, there is a striking discrepancy between the general agreement that joint attention is critical in various domains, and the lack of theoretical consensus on how (...)

  17. Why Frankfurt-Examples Don’t Need to Succeed to Succeed.Felipe Leon & Neal A. Tognazzini - 2010 - Philosophy and Phenomenological Research 80 (3):551-565.
    In this paper we argue that defenders of Frankfurt-style counterexamples to the Principle of Alternative Possibilities do not need to construct a metaphysically possible scenario in which an agent is morally responsible despite lacking the ability to do otherwise. Rather, there is a weaker (but equally legitimate) sense in which Frankfurt-style counterexamples can succeed. All that's needed is the claim that the ability to do otherwise is no part of what grounds moral responsibility, when the agent is indeed morally responsible.

    The Will to Synthesis: Nietzsche, Carnap and the Continental-Analytic Gap.Felipe G. A. Moreira - 2020 - Nietzsche Studien (1973) 49 (1):150-170.
    This essay presupposes that Friedrich Nietzsche and Rudolf Carnap champion contrasting reactions to the fact that, throughout history, persons have been engaged in metaphysical disputes. Nietzsche embraces a libertarian reaction that is in agreement with his anti-democratic aristocratic political views, whereas Carnap endorses an egalitarian reaction aligned with his democratic and socialist political views. After characterizing these reactions, the essay argues for two claims. The first claim is that the stated contrasting reactions are to be considered, not only by the (...)

    Overcoming Metametaphysics: Nietzsche and Carnap.Felipe G. A. Moreira - 2018 - Nietzsche Studien 47 (1):240-271.
    This essay focuses on the similarities between Nietzsche’s and Carnap’s views on metaphysics, without ignoring their obvious differences. The essay argues that Nietzsche and Carnap endorse but interpret differently an overcoming metametaphysics characterized by the conjunction of the following three claims: an overcoming of metaphysics ought to be performed; this overcoming is to be performed by adopting a method of linguistic analysis that is suspicious of the metaphysical use of language and that interprets such use through a different use of (...)

    An apology of Carnap.Felipe G. A. Moreira - 2014 - Manuscrito 37 (2):269-289.
    This paper is focused on dismissive metaontological views about ontology. The paper's first section deals with radical dismissivism: a view which I interpret as Carnap's. The second section approaches moderate dismissivism: a view which I interpret as Hirsch's. My first claim is stated in section three: that there are significant differences between the mentioned authors. However, current literature on metaontology, not only does not emphasize such differences, but also insinuates that they do not exist. The authors I have in mind (...)

    On Ultrafilter Logic and Special Functions.Paulo A. S. Veloso & Sheila R. M. Veloso - 2004 - Studia Logica 78 (3):459-477.
    Logics for generally were introduced for handling assertions with vague notions,such as generally, most, several, etc., by generalized quantifiers, ultrafilter logic being an interesting case. Here, we show that ultrafilter logic can be faithfully embedded into a first-order theory of certain functions, called coherent. We also use generic functions (akin to Skolem functions) to enable elimination of the generalized quantifier. These devices permit using methods for classical first-order logic to reason about consequence in ultrafilter logic.

    Consider three widely shared claims that have not been discussed vis-à-vis one another. In his Proslogion, Saint Anselm argued that the claim “God exists” is true. If an intuition that a claim c is a useful a-priori justificatory resource, this can only be because such an intuition is a justification that c is true. And if an intuition that c is a justification that c is true, c can stand, not only for mathematical or logical claims, but also for controversial (...)

    To be or not to be “subtly” philosophically colonized.Felipe G. A. Moreira - 2022 - Kriterion: Journal of Philosophy 63 (151):121-142.
    ABSTRACT An often-adopted use of the predicate, “to be colonized”, is one that applies it loosely, not in reference to original Africans or indigenous people enslaved by Europeans or heirs of enslaved persons, but to academics who are citizens of former colonies like Brazil, their ways of thinking, philosophical works, academic communities, etc. But under what conditions one is to do that? And how can one avoid the attribution of such predicate to oneself or one’s works? These issues have not (...)

    The conflictual craft.Felipe G. A. Moreira - 2019 - Manuscrito 42 (2):47-83.
    Are contemporary philosophers to follow Pyrrho of Elis in adopting his skeptic craft or at least core aspects of it as a reaction to the fact that, since immemorial times, persons have been engaged in disputes in metaphysics? Over the last 2500 years or so, most Western philosophers have not done so in being more influenced by Aristotle’s dogmatic craft than by Pyrrho’s skeptic one. Over the last fifty years or so, a few Brazilian neo-Pyrrhonist philosophers, such as Oswald Porchat, (...)

    A theory of magnitudes involves criteria for their comparison, equivalence and addition. We examine these aspects from an abstract viewpoint, stressing independence and definability. These considerations are triggered by the so-called De Zolt’s principle in the theory of equivalence of plane polygons.

    We compare fork arrow logic, an extension of arrow logic, and its natural first-order counterpart (the correspondence language) and show that both have the same expressive power. Arrow logic is a modal logic for reasoning about arrow structures, its expressive power is limited to a bounded fragment of first-order logic. Fork arrow logic is obtained by adding to arrow logic the fork modality (related to parallelism and synchronization). As a result, fork arrow logic attains the expressive power of its first-order (...)

    Perception, attention and demonstrative thought: In defense of a hybrid metasemantic mechanism.Felipe Nogueira de Carvalho - 2020 - Manuscrito 43 (2):16-53.
    Demonstrative thoughts are distinguished by the fact that their contents are determined relationally, via perception, rather than descriptively. Therefore, a fundamental task of a theory of demonstrative thought is to elucidate how facts about visual perception can explain how these thoughts come to have the contents that they do. The purpose of this paper is to investigate how cognitive psychology may help us solve this metasemantic question, through empirical models of visual processing. Although there is a dispute between attentional and (...)

  46. The biosemiotic implications of 'bacterial wisdom'.Felipe-Andres Piedra & Donald R. Frohlich - manuscript
    Eshel Ben-Jacob’s manuscript entitled ‘Bacterial wisdom, Gödel’s theorem and creative genomic webs’ summarizes decades of work demonstrating adaptive mutagenesis in bacterial genomes. Bacterial genomes, each an essential part of a Kantian whole that is a single bacterium, are thus not independent of the environment as sensed; and a single bacterium is therefore a semiotic entity. Ben-Jacob suggests this but errs in 1) assigning autonomy to the genome, and 2) analogizing through computation without making clear whether he is doing so for (...)

    This article investigates the relationship between emotional sharing and the extended mind thesis. We argue that shared emotions are socially extended emotions that involve a specific type of constitutive integration between the participating individuals’ emotional experiences. We start by distinguishing two claims, the Environmentally Extended Emotion Thesis and the Socially Extended Emotion Thesis. We then critically discuss some recent influential proposals about the nature of shared emotions. Finally, in Sect. 3, we motivate two conditions that an account of shared emotions (...)
