This text proposes an interpretation of the work of Franklin Leopoldo e Silva based on the reading of some of his numerous published articles and books, without neglecting the classes and guidance received from the stage of Scientific Initiation to Postdoctoral studies. Precisely, by highlighting the importance of three thinkers widely studied by Professor Franklin – Berkeley, Bergson and William James –, we suggest that at the heart of this philosophical experience there would be a constant: empiricism. Whether in the (...) classical or radical version, the line we draw in this multiplicity reveals an openness to concrete empiricism. (shrink)

Les évangéliques sont devenus une source inépuisable d’énigmes, de paniques et de poncifs, et un grand défi pour les forces progressistes. Leur croissance montre que la sécularisation ne fonctionne pas comme un mur capable d’annuler les échanges entre le monde de la religion et celui de la politique. Mais elle montre aussi des efficaces connexions entre le théologique et les croyances et les sensibilités populaires, matérialisées par la « théologie de la prospérité » et la guerre spirituelle.

We say that a sentence A is a permissive consequence of a set X of premises whenever, if all the premises of X hold up to some standard, then A holds to some weaker standard. In this paper, we focus on a three-valued version of this notion, which we call strict-to-tolerant consequence, and discuss its fruitfulness toward a unified treatment of the paradoxes of vagueness and self-referential truth. For vagueness, st-consequence supports the principle of tolerance; for truth, it supports the (...) requisite of transparency. Permissive consequence is non-transitive, however, but this feature is argued to be an essential component to the understanding of paradoxical reasoning in cases involving vagueness or self-reference.

To what degree can language be acquired from linguistic input alone? This question has vexed scholars for millennia and is still a major focus of debate in the cognitive science of language. The complexity of human language has hampered progress because studies of language–especially those involving computational modeling–have only been able to deal with small fragments of our linguistic skills. We suggest that the most recent generation of Large Language Models (LLMs) might finally provide the computational tools to determine empirically (...) how much of the human language ability can be acquired from linguistic experience. LLMs are sophisticated deep learning architectures trained on vast amounts of natural language data, enabling them to perform an impressive range of linguistic tasks. We argue that, despite their clear semantic and pragmatic limitations, LLMs have already demonstrated that human-like grammatical language can be acquired without the need for a built-in grammar. Thus, while there is still much to learn about how humans acquire and use language, LLMs provide full-fledged computational models for cognitive scientists to empirically evaluate just how far statistical learning might take us in explaining the full complexity of human language.

Michel Janssen and Harvey Brown have driven a prominent recent debate concerning the direction of an alleged arrow of explanation between Minkowski spacetime and Lorentz invariance of dynamical laws in special relativity. In this article, I critically assess this controversy with the aim of clarifying the explanatory foundations of the theory. First, I show that two assumptions shared by the parties—that the dispute is independent of issues concerning spacetime ontology, and that there is an urgent need for a constructive interpretation (...) of special relativity—are problematic and negatively affect the debate. Second, I argue that the whole discussion relies on a misleading conception of the link between Minkowski spacetime structure and Lorentz invari-ance, a misconception that in turn sheds more shadows than light on our understand-ing of the explanatory nature and power of Einstein’s theory. I state that the arrow connecting Lorentz invariance and Minkowski spacetime is not explanatory and uni-directional, but analytic and bidirectional, and that this analytic arrow grounds the chronogeometric explanations of physical phenomena that special relativity offers.

In this paper we investigate a semantics for first-order logic originally proposed by R. van Rooij to account for the idea that vague predicates are tolerant, that is, for the principle that if x is P, then y should be P whenever y is similar enough to x. The semantics, which makes use of indifference relations to model similarity, rests on the interaction of three notions of truth: the classical notion, and two dual notions simultaneously defined in terms of it, (...) which we call tolerant truth and strict truth. We characterize the space of consequence relations definable in terms of those and discuss the kind of solution this gives to the sorites paradox. We discuss some applications of the framework to the pragmatics and psycholinguistics of vague predicates, in particular regarding judgments about borderline cases. (shrink)

One way in which we might approach the challenge posed by the Sorites Paradox is considering that Sorites-susceptible predicates have several candidate extensions, or several ways in which these expressions can be made precise. For example, a candidate extension for the predicate ‘is a baby’ is the set of humans of less than two years, but also the set of those less than two years and one second, and of those less than two years and two seconds. In this chapter (...) we present and discuss two theories for vague predicates based on this idea: supervaluationism and subvaluationism. The chapter is structured in three parts. The first presents the super- and subvaluationist theories: their similarities and differences in the semantics, the resulting logics with their most characteristic features. The second reviews the super- and subvaluationist solutions to the Sorites Paradox and provides discussion on several controversies surrounding these theories. The third part introduces proof procedures for s’valuationist logics. (shrink)

When we speak about different interpretations of quantum mechanics it is suggested that there is one single quantum theory that can be interpreted in different ways. However, after an explicit characterization of what it is to interpret quantum mechanics, the right diagnosis is that we have a case of predictively equivalent rival theories. I extract some lessons regarding the resulting underdetermination of theory choice. Issues about theoretical identity, theoretical and methodological pluralism, and the prospects for a realist stance towards quantum (...) theory can be properly addressed once we recognize that interpretations of quantum mechanics are rival theories.

This paper presents and defends a way to add a transparent truth predicate to classical logic, such that and A are everywhere intersubstitutable, where all T-biconditionals hold, and where truth can be made compositional. A key feature of our framework, called STTT (for Strict-Tolerant Transparent Truth), is that it supports a non-transitive relation of consequence. At the same time, it can be seen that the only failures of transitivity STTT allows for arise in paradoxical cases.

According to a popular narrative, in 1932 von Neumann introduced a theorem that intended to be a proof of the impossibility of hidden variables in quantum mechanics. However, the narrative goes, Bell later spotted a flaw that allegedly shows its irrelevance. Bell’s widely accepted criticism has been challenged by Bub and Dieks: they claim that the proof shows that viable hidden variables theories cannot be theories in Hilbert space. Bub’s and Dieks’ reassessment has been in turn challenged by Mermin and (...) Schack. Hereby I critically assess their reply, with the aim of bringing further clarification concerning the meaning, scope and relevance of von Neumann’s theorem. I show that despite Mermin and Schack’s response, Bub’s and Dieks’ reassessment is quite correct, and that this reading gets strongly reinforced when we carefully consider the connection between von Neumann’s proof and Gleason’s theorem.

This paper is concerned with the claim that supervaluationist consequence is not classical for a language including an operator for definiteness. Although there is some sense in which this claim is uncontroversial, there is a sense in which the claim must be qualified. In particular I defend Keefe's position according to which supervaluationism is classical except when the inference from phi to Dphi is involved. The paper provides a precise content to this claim showing that we might provide complete (and (...) sound) systems of deduction for supervaluationist consequence in which proofs are completely classical with the exception of a single last step (involving the above mentioned inference).

In 1991 Larry Laudan and Jarret Leplin proposed a solution for the problem of empirical equivalence and the empirical underdetermination that is often thought to result from it. In this paper we argue that, even though Laudan and Leplin’s reasoning is essentially correct, their solution should be accurately assessed in order to appreciate its nature and scope. Indeed, Laudan and Leplin’s analysis does not succeed in completely removing the problem or, as they put it, in refuting the thesis of underdetermination (...) as a consequence of empirical equivalence. Instead, what they show is merely that science possesses tools that may eventually lead out of an underdetermination impasse. We apply their argument to a real case of two empirically equivalent theories: Lorentz’s ether theory and Einstein’s special relativity. This example illustrates the validity of Laudan and Leplin’s reasoning, but also shows the importance of the reassessment we argue for. (shrink)

It is a widespread belief that the Kochen-Specker theorem imposes a contextuality constraint on the ontology of beables in quantum hidden variables theories. On the other hand, after Bell’s influential critique, the importance of von Neumann’s wrongly called ‘impossibility proof’ has been severely questioned. However, Max Jammer, Jeffrey Bub and Dennis Dieks have proposed insightful reassessments of von Neumann’s theorem: what it really shows is that hidden variables theories cannot represent their beables by means of Hermitian operators in Hilbert space. (...) Hereby I show that i) the very same constraint can be derived from Gleason’s theorem, and that ii) if we consider the import of von Neumann’s and Gleason’s theorems, the relevance of the Kochen-Specker theorem for hidden variables theories gets substantially weakened: it does not force them to be contextual in any interesting sense of the term.

Substructural approaches to paradoxes have attracted much attention from the philosophical community in the last decade. In this paper we focus on two substructural logics, named ST and TS, along with two structural cousins, LP and K3. It is well known that LP and K3 are duals in the sense that an inference is valid in one logic just in case the contrapositive is valid in the other logic. As a consequence of this duality, theories based on either logic are (...) tightly connected since many of the arguments for and objections against one theory reappear in the other theory in dual form. The target of the paper is making explicit in exactly what way, if any, ST and TS are dual to one another. The connection will allow us to gain a more fine-grained understanding of these logics and of the theories based on them. In particular, we will obtain new insights on two questions concerning ST which are being intensively discussed in the current literature: whether ST preserves classical logic and whether it is LP in sheep’s clothing. Explaining in what way ST and TS are duals requires comparing these logics at a metainferential level. We provide to this end a uniform proof theory to decide on valid metainferences for each of the four logics. This proof procedure allows us to show in a very simple way how different properties of inferences (unsatisfiability, supersatisfiability and antivalidity) that behave in very different ways for each logic can be captured in terms of the validity of a metainference.

In this paper I argue that the case of Einstein׳s special relativity vs. Hendrik Lorentz׳s ether theory can be decided in terms of empirical evidence, in spite of the predictive equivalence between the theories. In the historical and philosophical literature this case has been typically addressed focusing on non-empirical features. I claim that non-empirical features are not enough to provide a fully objective and uniquely determined choice in instances of empirical equivalence. However, I argue that if we consider arguments proposed (...) by Richard Boyd, and by Larry Laudan and Jarret Leplin, a choice based on non-entailed empirical evidence favoring Einstein׳s theory can be made.

Human dignity: social movements invoke it, several national constitutions enshrine it, and it features prominently in international human rights documents. But what is it, why is it important, and what is its relationship to human rights and social justice? Pablo Gilabert offers a systematic defence of the view that human dignity is the moral heart of justice. In Human Dignity and Human Rights (OUP 2019), he advanced an account of human dignity for the context of human rights discourse, which (...) covers the most urgent, basic claims of dignity. This book extends the dignitarian approach to more ambitious claims of maximal dignity of the kind encoded in democratic socialist conceptions of social justice. In particular, this book focuses on the just organization of working practices. It recasts in a dignitarian format the critique of capitalist society as involving exploitation, alienation, and domination of workers, and revamps a neglected but inspiring socialist principle. In its dignitarian interpretation, the Abilities/Needs Principle (‘From each according to their ability, to each according to their needs!’) yields reasonable and feasible requirements on social cooperation geared to empowering each human being to lead a flourishing life. While Human Dignity and Human Rights offered the first systematic philosophical account of human dignity in human rights discourse, Human Dignity and Social Justice presents the first systematic application of the dignitarian framework to the core ideals of democratic socialism.

In this paper I analyze three artificial examples of empirical equivalence: van Fraassen’s alternative formulations of Newton’s theory, the Poincaré-Reichenbach argument for the conventionality of geometry; and predictively equivalent ‘systems of the world’. These examples have received attention in the philosophy of science literature because they are supposed to illustrate the connection between predictive equivalence and underdetermination of theory choice. I conclude that this view is wrong. These examples of empirical equivalence are harmless with respect to the problem of underdetermination.

The purpose of this paper is to analyze the virtue of temperance as a moral competence in professional performance. The analysis relies on three different streams of literature: virtue ethics, positive psychology and competency-based management. The paper analyzes how temperance is defined in each of these perspectives. The paper proposes an integrative definition of temperance as “moral competence” and summarizes behaviors in business environments in which temperance plays a role.

En este artículo discuto la relevancia que tiene el autorrespeto en la teoría de la justicia de Rawls. Para alcanzar dicho objetivo, en primer lugar examino las nociones de valor moral y mérito y su vinculación con el autorrespeto como forma de autovaloración. En segundo lugar, especifico las bases que sustentan el autorrespeto al interior de su teoría. Finalmente, discuto la función que tiene el autorrespeto en la justificación de los principios de la justicia como equidad.

En este artículo discuto la importancia que tiene para la teoría de la justicia de Rawls el desarrollo del sentido de la justicia como condición para la estabilidad social. Para cumplir con dicho objetivo analizo la interpretación que Rawls ofrece de nuestra psicología moral con la finalidad de evaluar su rol en la aceptación de los principios de justicia, así como las razones para fundar dicha estabilidad en determinados sentimientos morales. El análisis anterior me permitirá concluir que la búsqueda de (...) bases naturales para fundar los sentimientos morales constituye para Rawls una vía alternativa tanto al deductivismo moral, así como a cualquier forma de fundamentación metafísica de los principios que guían nuestras prácticas sociales.

Les gouvernements de gauche néolibéraux ont mélangé promesses d’émancipation et réalité de la financiarisation, ce qui a révolté les gens et poussé l’opinion publique à droite. L’article met en scène un jeune philosophe italien très médiatisé passé du marxisme à la revendication de l’autorité. Le confusionnisme actuel se satisfait des performances des comiques issus des minorités qui parviennent à ridiculiser les hommes de droite que la rhétorique de gauche n’atteint plus.

This paper discusses Fara's so-called 'Paradox of Higher-Order Vagueness' concerning supervaluationism. In the paper I argue that supervaluationism is not committed to global validity, as it is largely assumed in the literature, but to a weaker notion of logical consequence I call 'regional validity'. Then I show that the supervaluationist might solve Fara's paradox making use of this weaker notion of logical consequence. The paper is discussed by Delia Fara in the same volume.

It is common in political theory and practice to challenge normatively ambitious proposals by saying that their fulfillment is not feasible. But there has been insufficient conceptual exploration of what feasibility is, and very little substantive inquiry into why and how it matters for thinking about social justice. This paper provides one of the first systematic treatments of these issues, and proposes a dynamic approach to the relation between justice and feasibility that illuminates the importance of political imagination and dynamic (...) duties to expand agents’ power to fulfill ambitious principles of justice.

Do we have positive duties to help others in need or are our moral duties only negative, focused on not harming them? Are any of the former positive duties, duties of justice that respond to enforceable rights? Is their scope global? Should we aim for global equality besides the eradication of severe global poverty? Is a humanist approach to egalitarian distribution based on rights that all human beings as such have defensible, or must egalitarian distribution be seen in an associativist (...) way, as tracking existing frameworks such as statehood and economic interdependence? Are the eradication of global poverty and the achievement of global equality practically feasible or are they hopelessly utopian wishes? -/- This book argues that there are basic positive duties of justice to help eradicate severe global poverty; that global egalitarian principles are also reasonable even if they cannot be fully realized in the short term; and that there are dynamic duties to enhance the feasibility of the transition from global poverty to global equality in the face of nonideal circumstances such as the absence of robust international institutions and the lack of a strong ethos of cosmopolitan solidarity. The very notion of feasibility is crucial for normative reasoning, but has received little explicit philosophical discussion. This book offers a systematic exploration of that concept as well as of its application to global justice. It also arbitrates the current debate between humanist and associativist accounts of the scope of distributive justice. Drawing on moral contractualism (the view that we ought to follow the principles that no one could reasonably reject), this book provides a novel defense of humanism, challenges several versions of associativism (which remains the most popular view among political philosophers), and seeks to integrate the insights underlying both views.

Determinar el estatuto del embrión humano no es una tarea fácil y menos cuando existen realidades y propuestas diversas en torno al mismo. Si bien tratar de describir qué es una persona, resulta ya complejo por las dimensiones sociales, biológicas, psicológicas y espirituales que se involucran; cuando a ello le agregamos el valor antropológico,legal, ontológico y biológico del desarrollo de la persona, se complica todavía más. No obstante, cuando entendemos que no es adecuado generar conflicto entre disciplinas, sino, por el (...) contrario, que nuestra labor es la de dialogar y comprender que todos estamos trabajando con una misma realidad, podemos entonces vincular al ser humano en todas sus dimensiones, ver su integralidad y rescatar el valor originario del ser humano desde su concepción hasta su muerte.

This essay explores the relation between two perspectives on the nature of human rights. According to the "political" or "practical" perspective, human rights are claims that individuals have against certain institutional structures, in particular modern states, in virtue of interests they have in contexts that include them. According to the more traditional "humanist" or "naturalistic" perspective, human rights are pre-institutional claims that individuals have against all other individuals in virtue of interests characteristic of their common humanity. This essay argues that (...) once we identify the two perspectives in their best light, we can see that they are complementary and that in fact we need both to make good normative sense of the contemporary practice of human rights. It explains how humanist and political considerations can and should work in tandem to account for the concept, content, and justification of human rights. (shrink)

What should our theorizing about social justice aim at? Many political philosophers think that a crucial goal is to identify a perfectly just society. Amartya Sen disagrees. In The Idea of Justice, he argues that the proper goal of an inquiry about justice is to undertake comparative assessments of feasible social scenarios in order to identify reforms that involve justice-enhancement, or injustice-reduction, even if the results fall short of perfect justice. Sen calls this the “comparative approach” to the theory of (...) justice. He urges its adoption on the basis of a sustained critique of the former approach, which he calls “transcendental.” In this paper I pursue two tasks, one critical and the other constructive. First, I argue that Sen’s account of the contrast between the transcendental and the comparative approaches is not convincing, and second, I suggest what I take to be a broader and more plausible account of comparative assessments of justice. The core claim is that political philosophers should not shy away from the pursuit of ambitious theories of justice (including, for example, ideal theories of perfect justice), although they should engage in careful consideration of issues of political feasibility bearing on their practical implementation.

In this paper, I develop a quasi-transcendental argument to justify Kant’s infamous claim “man is evil by nature.” The cornerstone of my reconstruction lies in drawing a systematic distinction between the seemingly identical concepts of “evil disposition” (böseGesinnung) and “propensity to evil” (Hang zumBösen). The former, I argue, Kant reserves to describe the fundamental moral outlook of a single individual; the latter, the moral orientation of the whole species. Moreover, the appellative “evil” ranges over two different types of moral failure: (...) while an “evil disposition” is a failure to realize the good (i.e., to adopt the motive of duty as limiting condition for all one’s desires), an “evil propensity” is a failure to realize the highest good (i.e., to engage in the collective project of transforming the legal order into an ethical community). This correlation between units of moral analysis and types of obligation suggests a way to offer a deduction of the universal propensity on behalf of Kant. It consists in tracing the source of radical evil to the same subjective necessity that gives rise to the doctrine of the highest good. For, at the basis of Kant’s two doctrines lies the same natural dialectic between happiness and morality. While the highest good brings about the critically acceptable resolution of this dialectic, the propensity to evil perpetuates and aggravates it. Instead of connecting happiness and morality in an objective relation, the human will subordinatesmorality to the pursuit of happiness according to the subjective order of association. If this reading is correct, it would explain why prior attempts at a transcendental deduction have failed: interpreters have looked for the key to the deduction in the body of Kant’s text, where it is not to be found, for it is tucked, instead, in the Preface to the first edition.

A commitment to ‘making’—creating or producing things—can shape scientific and technological fields in important ways. This article demonstrates this by exploring synthetic biology, a field committed to making use of advanced techniques from molecular biology in order to make with living matter. I describe and analyse how this field’s ‘drive to make’ shapes its organisational, methodological, epistemological, and ontological character. Synthetic biologists’ ambition to make helps determine how their field demarcates itself, sets appropriate methods and practices, construes the purpose and (...) character of knowledge, and views the things of the living world. Using empirical data from extensive ethnographic and interview-based research, I discuss the importance of seemingly simple and unimportant commitments—in this case, a focus on the making of things rather than the production of knowledge claims. I conclude by examining the ramifications of this line of research for studies of science and technology. (shrink)

A considerable number of books and papers have analyzed normative concepts using new techniques developed by logicians; however, few have bridged the gap between the English legal culture and the Continental tradition in legal philosophy. This book addresses this issue by offering an introductory study on the many possibilities that logical analysis offers the study of legal systems. The volume is divided into two sections: the first covers the basic aspects of classical and deontic logic and its connections, advancing an (...) explanation of the most important topics of the discipline by comparing different systems of deontic logic and exploring some of the most important paradoxes in its domain. The second section deals with the role of logic in the analysis of legal systems by discussing in what sense deontic logic and the logic of norm-propositions are useful tools for a proper understanding of the systematic structure of law.

In a recent paper, Barrio, Tajer and Rosenblatt establish a correspondence between metainferences holding in the strict-tolerant logic of transparent truth ST+ and inferences holding in the logic of paradox LP+. They argue that LP+ is ST+’s external logic and they question whether ST+’s solution to the semantic paradoxes is fundamentally different from LP+’s. Here we establish that by parity of reasoning, ST+ can be related to LP+’s dual logic K3+. We clarify the distinction between internal and external logic and (...) argue that while ST+’s nonclassicality can be granted, its self-dual character does not tie it to LP+ more closely than to K3+.
