This paper contains five observations concerning the intended meaning of the intuitionistic logical constants: (1) if the explanations of this meaning are to be based on a non-decidable concept, that concept should not be that of `proof"; (2) Kreisel"s explanations using extra clauses can be significantly simplified; (3) the impredicativity of the definition of → can be easily and safely ameliorated; (4) the definition of → in terms of `proofs from premises" results in a loss of the inductive character of (...) the definitions of ∨ and ∃ and (5) the same occurs with the definition of ∀ in terms of `proofs with free variables".

A distinction is introduced between itemized and non-itemized plural predication. It is argued that a full-fledged system of plural logic is not necessary in order to account for the validity of inferences concerning itemized collective predication. Instead, it is shown how this type of inferences can be adequately dealt with in a first-order logic system, after small modifications on the standard treatment. The proposed system, unlike plural logic, has the advantage of preserving completeness. And as a result, inferences such as (...) ‘Dick and Tony emptied the bottle, hence Tony and Dick emptied the bottle’ are shown to be first-order. (shrink)

This paper is based on a criterion recently proposed by Richard Fumerton for demarcating philosophy of mind and cognitive science. I suggest to extend it to a demarcation criterion between philosophy and science in general, and put it in the context of the historical changes of boundaries between the philosophical and the scientifi c fi eld. I point to a number of philosophical claims and approaches that have been made utterly obsolete by the advancement of science, and conjecture that a (...) similar thing may happen in the future with today’s philosophy of mind: under the supposition that cognitive science manages to progress very successfully in a certain direction, our concepts for mental states could change, and the type of philosophical interest we put in them, thus reshaping thewhole debate on the subject.

Este capítulo examina una posible preocupación filosófica especializada por la técnica en la práctica filosófica colombiana. Se argumenta, según las fuentes consultadas: una génesis, un desarrollo; con unas rupturas, continuidades y una consolidación reciente de una comunidad académica en el asunto. Este hecho cultural se registra en un corpus documental compuesto por artículos de revistas especializadas de filosofía, obras de filósofos colombianos, memorias de congresos nacionales de filosofía en los que registran coloquios y ponencias en esta materia, en los currículos (...) de los programas de filosofía, tanto en pregrado como posgrado, en los que aparecen cátedras en filosofía de la técnica o tecnologías, y proyectos de investigación con tesis en esta especialidad. Estas y otras prácticas académicas permiten concluir de la existencia de una discusión filosófica de la técnica; similar a lo que sucede en otros países de Iberoamérica y a nivel mundial. Para desglosar tal conjetura en este apartado se precisa cómo surge la deliberación de la técnica en la tradición filosófica. Luego, se examina cómo emerge el tema en el contexto filosófico colombiano, y puntualiza la obra de Danilo Cruz Vélez en torno a una filosofía de la técnica. Finalmente, se llegará a unas conclusiones parciales que demuestren los aportes de la comunidad filosófica colombiana en dicha temática. La demostración de la hipótesis se sustenta teórica y metodológicamente con dos criterios: uno hermenéutico, con técnicas de interpretación filológica, histórica, filosófica y otro bibliométrico, los cuales permiten una reconstrucción, síntesis, análisis e interpretación de las deliberaciones del tema, desde 1964 al 2018.

Conceptual engineering is commonly characterized as the method for assessing and improving our representational devices. Little has been said, however, on how best to construe these representational devices—in other words, on what conceptual engineering should be all about. This paper tackles this problem with a basic strategy: First, by presenting a taxonomy of the different possible subject matters for conceptual engineering; then, by comparatively assessing them and selecting the most conducive one with a view to making conceptual engineering an actionable (...) method, that is, a method that can be applied effectively and consistently to specific case studies. The outcome is that conceptual engineering should be all about concepts on pain of pragmatic inconsistencies otherwise. (shrink)

I present a discussion of some issues in the ontology of spacetime. After a characterisation of the controversies among relationists, substantivalists, eternalists, and presentists, I offer a new argument for rejecting presentism, the doctrine that only present objects exist. Then, I outline and defend a form of spacetime realism that I call event substantivalism. I propose an ontological theory for the emergence of spacetime from more basic entities. Finally, I argue that a relational theory of pre-geometric entities can give rise (...) to substantival spacetime in such a way that relationism and substantivalism are not necessarily opposed positions, but rather complementary. In an appendix I give axiomatic formulations of my ontological views. (shrink)

Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

Black holes are arguably the most extraordinary physical objects we know in the universe. Despite our thorough knowledge of black hole dynamics and our ability to solve Einstein’s equations in situations of ever increasing complexity, the deeper implications of the very existence of black holes for our understanding of space, time, causality, information, and many other things remain poorly understood. In this paper I survey some of these problems. If something is going to be clear from my presentation, I hope (...) it will be that around black holes science and metaphysics become more interwoven than anywhere else in the universe. (shrink)

I present a formal ontological theory where the basic building blocks of the world can be either things or events. In any case, the result is a Parmenidean worldview where change is not a global property. What we understand by change manifests as asymmetries in the pattern of the world-lines that constitute 4-dimensional existents. I maintain that such a view is in accord with current scientific knowledge.

The Modern concept of truth, which subjects truth to certainty, broke the harmonious relation between reality and truth, that prevailed in Ancient and Medieval Philosophy. Hans-Georg Gadamer thinks that the main task of contemporary Philosophy is to recover the original harmony of being and knowledge. To shed light on the nature of this problem, we expound the metaphysical-theological foundation of truth, which is at the roots of Aristotelian and Thomistic Philosophies. Specifically, we analyze here the relation between being, truth and (...) logos in the Aristotelian treatise Perì Hermeneías, and in its Thomistic commentary. (shrink)

I argue that there are no physical singularities in space–time. Singular space–time models do not belong to the ontology of the world, because of a simple reason: they are concepts, defective solutions of Einstein’s field equations. I discuss the actual implication of the so-called singularity theorems. In remarking the confusion and fog that emerge from the reification of singularities I hope to contribute to a better understanding of the possibilities and limits of the theory of general relativity.

A supertask consists in the performance of an infinite number of actions in a finite time. I show that any attempt to carry out a supertask will produce a divergence of the curvature of spacetime, resulting in the formation of a black hole. I maintain that supertaks, contrarily to a popular view among philosophers, are physically impossible. Supertasks, literally, collapse under their own weight.

In this essay I address the question, “What is the subject matter of phenomenological research?” I argue that in spite of the increasing popularity of phenomenology, the answers to this question have been brief and cursory. As a result, contemporary phenomenologists lack a clear framework within which to articulate the aims and results of their research, and cannot easily engage each other in constructive and critical discourse. Examining the literature on phenomenology’s identity, I show how the question of phenomenology’s subject (...) matter has been systematically neglected. It has been overshadowed by an unending concern with phenomenology’s methodological identity. However, an examination of recent contributions to this literature reveals that a concern with articulating phenomenology’s subject matter has gradually increased, although such articulations remain preliminary. In light of this, I delineate, define, and illustrate three layers of phenomenological research, which I term “existentials,” “modes,” and “prejudices.” While the delineation of these layers is drawn primarily from classical phenomenological texts, they are defined and illustrated through the use of more contemporary literature. Following the articulation of this subject matter, I briefly consider some of the debates—both foundational and applied—that can be facilitated by the adoption of this framework. (shrink)

The present article is the third part of a trilogy of papers, devoted to analysing the influence of semantic Platonism on contemporary philosophy of language. In Part I (Picazo 2021), the discussion was set out by examining a number of typical traces of Platonism in semantic theory since Frege. In Part II (Picazo 2021a), additional illustrations of such traces were provided, taken from a collection of recent commissioned essays on the philosophy of language (Schantz 2012). The present part is devoted (...) to providing yet additional illustrations of such traces, taken from a collection of classic essays on the subject: the book Modern Philosophy of Language, edited by Maria Baghramian in 1998. We shall, thus, describe a number of examples in which the influence of semantic Platonism on these essays can be felt. Prominent among these examples are the confusion between sentences and propositions (and related confusions), the avoidant attitude with respect to basic aspects of linguistic meaning, the overuse of analytic methodology for semantic research, the adoption of a background Platonic metaphysics of meanings and the overreaction against semantic Platonism and germane views, witnessing an inverse influence (‘by opposition’) from these views.

Contemporary psychiatry finds itself in the midst of a crisis of classification. The developments begun in the 1980s—with the third edition of the Diagnostic and Statistical Manual of Mental Disorders —successfully increased inter-rater reliability. However, these developments have done little to increase the predictive validity of our categories of disorder. A diagnosis based on DSM categories and criteria often fails to accurately anticipate course of illness or treatment response. In addition, there is little evidence that the DSM categories link up (...) with genetic findings, and even less evidence that they... (shrink)

I present a condensed exposé of systemic materialism, a synthesis of materialism and systemism originally proposed by Mario Bunge. Matter is identified with mutability of propertied particulars, and a concrete or material system is defined as an object with composition, structure, mechanism, and environment. I review different aspects of this ontology, and discuss some of its implications for epistemology, ethics, and aesthetics. I also try to identify some problems of this view and offer some ways to overcome the difficulties. I (...) conclude that systemic materialism is a promising philosophical project still in the making. (shrink)

In Metaphysics A.4, Aristotle provides crucial information about fundamental aspects of the chemistry and microphysics of the atomic theory of Leucippus and Democritus of Abdera. Besides the plenum and the void, which he identifies as the elements of the atomic theory, he presents what he himself names as differences. These fundamental differences are named so because they ought to be responsible for the emergence of all other differences in the physical world, and especially the ones that hit our senses. Aristotle (...) provides a list of three differences both in what is recognized as autochthonous terminology from Leucippus and Democritus, and in a translation to terms apparently more intelligible to Aristotelian listeners. Among those differences there is one in particular that is harder to comprehend than the other ones: rhysmos. Aristotle’s translation of rhysmos into schēma has led most interpreters to acknowledge that it referred solely to atoms individually, while the other two differences would refer to relations between atoms. In this paper, I want to propose an interpretation in which rhysmos actually refers to several aspects of the chemistry and microphysics of the atomic theory. (shrink)

This paper discusses the logical space of alternative conceptual engineering projects, with a specific focus on (1) the processes, (2) the targets and goals, and (3) the methods of such projects. We present an overview of how these three aspects interact in the contemporary literature and discuss those alternative projects that have yet to be explored based on our suggested typology. We show how choices about each element in a conceptual engineering project constrain the possibilities for the others, thereby giving (...) rise to distinct groupings of possible projects under the banner of conceptual engineering. We conclude with a critical reflection on the potential ethical issues that arise as a result of effectively putting conceptual engineering into practice. (shrink)

En este trabajo nos proponemos elucidar el concepto de bíos desarrollado por Foucault en su curso recientemente publicado, Subjectivité et vérité,estableciendo su desarrollo luego con la noción de "vida bella" presentada en su Historia de la sexualidad, para finalmente analizar un tipo específico de bíos, el de los cínicos, que transita entre la crudeza de la parresía y la animalidad.

I discuss the ontological assumptions and implications of General Relativity. I maintain that General Relativity is a theory about gravitational fields, not about space-time. The latter is a more basic ontological category, that emerges from physical relations among all existents. I also argue that there are no physical singularities in space-time. Singular space-time models do not belong to the ontology of the world: they are not things but concepts, i.e. defective solutions of Einstein’s field equations. I briefly discuss the actual (...) implication of the so-called singularity theorems in General Relativity and some problems related to ontological assumptions of Quantum Gravity. (shrink)

The ontology behind quantum mechanics has been the subject of endless debate since the theory was formulated some 100 years ago. It has been suggested, at one time or another, that the objects described by the theory may be individual particles, waves, fields, ensembles of particles, observers, and minds, among many other possibilities. I maintain that these disagreements are due in part to a lack of precision in the use of the theory’s various semantic designators. In particular, there is some (...) confusion about the role of representation, reference, and denotation in the theory. In this article, I first analyze the role of the semantic apparatus in physical theories in general and then discuss the corresponding ontological implications for quantum mechanics. Subsequently, I consider the extension of the theory to quantum fields and then analyze the semantic changes of the designators with their ontological consequences. In addition to the classical arguments to rule out a particle ontology in the case of non-relativistic quantum field theory, I show how the existence of black holes makes the proposal of a particle ontology in general spacetimes unfeasible. I conclude by proposing a provisional pluralistic ontology of fields and spacetime and discussing some prospects for possible future ontological economies. (shrink)

Este trabajo se propone pensar las relaciones entre el ejercicio del gobierno y los regímenes de veridicción, teniendo como eje las problematizaciones planteadas por Michel Foucault en el curso titulado Du gouvernement des vivants.

This is the introduction to the Special Issue ‘Foundational Issues in Conceptual Engineering’. The issue contains contributions by James Andow, Delia Belleri, David Chalmers, Catarina Dutilh Novaes, Eugen Fischer, Viktoria Knoll, Edouard Machery and Amie Thomasson. We, the editors, provide a brief introduction to the main topics of the issue and then summarize its contributions.

The idea of a moving present or ‘now’ seems to form part of our most basic beliefs about reality. Such a present, however, is not reflected in any of our theories of the physical world. I show in this article that presentism, the doctrine that only what is present exists, is in conflict with modern relativistic cosmology and recent advances in neurosciences. I argue for a tenseless view of time, where what we call ‘the present’ is just an emergent secondary (...) quality arising from the interaction of perceiving self-conscious individuals with their environment. I maintain that there is no flow of time, but just an ordered system of events. (shrink)

In this note I present a solution to Kripkenstein’s paradox, based on a very simple argument: (1) natural language and rule-following are empirical phenomena; (2) no case has been described, in real life, of a person who behaves as Wittgenstein’s or Kripke’s fictional character; (3) therefore, the discussion of such a case is completely devoid of interest. I lay out the example of a ‘Kripkensteinian apple’, which has a normal weight on even days and is weightless on odd days, in (...) order to highlight the contrast between a genuinely empirical perspective, such as that of physics, and the logical-analytical perspective, under which Kripkenstein’s paradox has attracted so much attention.

In this paper I argue that the idiosyncrasy of linguistic competence fosters semantic conceptions in which meanings are taken for granted, such as the one that Quine calls ‘uncritical semantics’ or ‘the myth of the museum’. This is due to the degree of automaticity in the use of language which is needed for fluent conversation. Indeed, fluent conversation requires that we speakers instinctively associate each word or sentence with its meaning (or linguistic use), and instinctively resort to the conceptual repertoire (...) of our language, without calling into question that the meaning of a particular word, or the conceptual repertoire of our language, could have been different than they are. This habit of taking meanings for granted, inherent to our linguistic ability, sometimes interferes with our semantic research, hampering it. In order to illustrate this problem, I pinpoint four places in Quine’s work where, despite his acknowledged analytical rigour, and despite his congenital aversion to the habit of taking meanings for granted, he himself appears to slip into this habit, inadvertently.

Macroscopic irreversible processes emerge from fundamental physical laws of reversible character. The source of the local irreversibility seems to be not in the laws themselves but in the initial and boundary conditions of the equations that represent the laws. In this work we propose that the screening of currents by black hole event horizons determines, locally, a preferred direction for the flux of electromagnetic energy. We study the growth of black hole event horizons due to the cosmological expansion and accretion (...) of cosmic microwave background radiation, for different cosmological models. We propose generalized McVittie co-moving metrics and integrate the rate of accretion of cosmic microwave background radiation onto a supermassive black hole over cosmic time. We find that for flat, open, and closed Friedmann cosmological models, the ratio of the total area of the black hole event horizons with respect to the area of a radial co-moving space-like hypersurface always increases. Since accretion of cosmic radiation sets an absolute lower limit to the total matter accreted by black holes, this implies that the causal past and future are not mirror symmetric for any spacetime event. The asymmetry causes a net Poynting flux in the global future direction; the latter is in turn related to the ever increasing thermodynamic entropy. Thus, we expose a connection between four different “time arrows”: cosmological, electromagnetic, gravitational, and thermodynamic. (shrink)

This is the introductory essay to the Italian translation of Anthony de Jasay's "Choice, contract, and consent. A restatement of liberalism".

In this paper, I present a conception of meaning in natural language that I call the ‘process model’. According to this conception, meaning must be regarded as the result of a process of interaction in a community of cognitive-linguistic agents, with one another and with the environment. Drawing on this understanding, I argue that the study of meaning should no longer focus on logical analysis, but rather on an empirical perspective similar to the one in the other social sciences. I (...) briefly compare this view with semantic Platonism, as well as with Wittgenstein’s and Quine’s approaches to meaning. Finally, I outline a way in which this approach could be applied to two current problems in the philosophy of language: the treatment of linguistic vagueness and the definition of truth. The treatment of all these questions is very cursory, as a sort of travel guide for a future more detailed research. (shrink)

Conceptual engineering means to provide a method to assess and improve our concepts working as cognitive devices. But conceptual engineering still lacks an account of what concepts are (as cognitive devices) and of what engineering is (in the case of cognition). And without such prior understanding of its subject matter, or so it is claimed here, conceptual engineering is bound to remain useless, merely operating as a piecemeal approach, with no overall grip on its target domain. The purpose of this (...) programmatic paper is to overcome this knowledge gap by providing some guidelines for developing the theories of concepts and of cognition that will ground the systematic unified framework needed to effectively implement conceptual engineering as a widely applicable method for the cognitive optimization of our conceptual devices.

Conceptual engineering is the method for assessing and improving our concepts. Some have recently claimed that the implementation of such method in the form of ameliorative projects is truth-driven and should thus be epistemically constrained, ultimately at least (Simion 2018; cf. Podosky 2018). This paper challenges that claim on the assumption of a social constructionist analysis of ideologies, and provides an alternative, pragmatic and cognitive framework for determining the legitimacy of ameliorative conceptual projects overall. The upshot is that one should (...) not ameliorate for the sake of truth or knowledge, in the case of ideologies—at least, not primarily. (shrink)

I present a discussion of some open issues in the philosophy of space-time theories. Emphasis is put on the ontological nature of space and time, the relation between determinism and predictability, the origin of irreversible processes in an expanding Universe, and the compatibility of relativity and quantum mechanics. In particular, I argue for a Parmenidean view of time and change, I make clear the difference between ontological determinism and predictability, propose that the origin of the asymmetry observed in physical processes (...) is related to the existence of cosmological horizons, and present a non-local concept of causality that can accommodate both special relativity and quantum entanglement.

In this article, we develop a new approach to integrating philosophical phenomenology with qualitative research. The approach uses phenomenology’s concepts, namely existentials, rather than methods such as the epoché or reductions. We here introduce the approach to both philosophers and qualitative researchers, as we believe that these studies are best conducted through interdisciplinary collaboration. In section 1, we review the debate over phenomenology’s role in qualitative research and argue that qualitative theorists have not taken full advantage of what philosophical phenomenology (...) has to offer, thus motivating the need for new approaches. In section 2, we introduce our alternative approach, which we call Phenomenologically Grounded Qualitative Research (PGQR). Drawing parallels with phenomenology’s applications in the cognitive sciences, we explain how phenomenological grounding can be used to conceptually front-load a qualitative study, establishing an explicit focus on one or more structures of human existence, or of our being in the world. In section 3, we illustrate this approach with an example of a qualitative study carried out by one of the authors: a study of the existential impact of early parental bereavement. In section 4, we clarify the kind of knowledge that phenomenologically grounded studies generate and how it may be integrated with existing approaches. (shrink)

Many approaches have been taken regarding this topic, some of them are anthropological or scientific that pursue the understanding of why we eat meat, but from the philosophical lens this question is solved in the field of applied ethics, which is the area that debate about the moral status of animals (nonhuman animals) and where different theorizations that tried to explain the relationship between animals and humans and the examination of the morality of meat consumption take place. Some of these (...) approaches could be find within the concepts of animal rights, vegetarianism, animal cruelty and so on. (shrink)

The application of Artificial Intelligence (AI) in healthcare and epidemiology undoubtedly has many benefits for the population. However, due to its environmental impact, the use of AI can produce social inequalities and long-term environmental damages that may not be thoroughly contemplated. In this paper, we propose to consider the impacts of AI applications in medical care from the One Health paradigm and long-term global health. From health and environmental justice, rather than settling for a short and fleeting green honeymoon between (...) health and sustainability caused by AI, it should aim for a lasting marriage. To this end, we conclude by proposing that, in the upcoming years, it could be valuable and necessary to promote more interconnected health, call for environmental cost transparency, and increase green responsibility.

Este artigo analisa a discussão sobre o Dilema Darwiniano para o realismo metaético, proposto por Sharon Street (2006), e entende o seu “debunking” como estruturas aporéticas. Street desenvolve um dilema específico para o realismo metaético em que as verdades avaliativas pressupostas porela estariam em desarmonia com uma perspectiva evolutiva-darwiniana da moralidade. Street mostra que o realismo não consegue fornecer uma explicação boa o suficiente sobre a relação entre o processo evolutivo e nossos juízos morais verdadeiros. Ela propõe uma explicação metaética (...) antirrealista alternativa, coerente com a explicação evolutiva da moralidade. Da perspectiva de Nicholas Rescher (1985), mostraremos que o Dilema Darwiniano para o realismo moral, apontado por Street, pode ser analisado de forma aporética. De acordo com Rescher, aporias se apresentam como inconsistências dentro de um conjunto de comprometimentos teóricos, que formarão estruturas aporéticas que demandarão ou a rejeição ou a justificação destes comprometimentos teóricos responsáveis pelas aporias no conjunto total. Indicaremos que a perspectiva antirrealista de Street também engendra aporias, assim como o realismo, e pelas mesmas bases, poderá ser rejeitada. Por fim iremos propor uma abordagem pluralista para a metaética, na qual os méritos explicativos das teorias devem ser utilizados para esclarecer o fenômeno moral. (shrink)

Conceptual engineering is the method for assessing and improving our concepts. However, little has been written about how best to conceive of concepts for the purposes of conceptual engineering. In this paper, I aim to fill this foundational gap, proceeding in three main steps: First, I propose a methodological framework for evaluating the conduciveness of a given concept of concept for conceptual engineering. Then, I develop a typology that contrasts two competing concepts of concept that can be used in conceptual (...) engineering — namely, the philosophical and psychological ones. Finally, I evaluate these two concepts of concept using the proposed methodological framework and I show that, when it comes to making conceptual engineering an actionable method, the psychological concept of concept outclasses its philosophical counterpart on all counts. This provides a baseline from which the concept of concept can be further improved for the purposes of conceptual engineering. (shrink)

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

The epistemic status of Natural Selection has intrigued to biologists and philosophers since the very beginning of the theory to our present times. One prominent contemporary example is Elliott Sober, who claims that Natural Selection, and some other theories in biology, and maybe in economics, are peculiar in including explanatory models/conditionals that are a priori in a sense in which explanatory models/conditionals in Classical Mechanics and most other standard theories are not. In this paper, by analyzing what we take to (...) be the four possible interpretations of Sober’s claim, we argue that, terminological preferences aside, the possible senses in which explanatory models in Natural Selection can qualify, or include elements that can qualify, as a priori, also apply to Classical Mechanics and other standard, highly unified theories.
