Defeasible argumentation has been applied successfully in several real-world domains in which it is necessary to handle incomplete and contradictory information. In recent years, there have been interesting attempts to carry out argumentation processes supported by massive repositories developing argumentative reasoning applications. One of such efforts builds arguments by retrieving information from relational databases using the DBI-DeLP framework; this article presents eDBI-DeLP, which extends the original DBI-DeLP framework by providing two novel aspects which refine the interaction between DeLP programs and (...) relational databases. First, we expand the expressiveness of dbi-delp programs by providing ways of controlling how the information in databases is recovered; this is done by introducing filters that enable an improved fine-grained control on the argumentation processes which become useful in applications, providing the semantics and the implementation of such filters. Second, we introduce an argument comparison criterion which can be adjusted at the level of literals to model particular features such as credibility and topic expertise, among others. These new tools can be particularly useful in environments such as medical diagnosis expert systems, decision support systems, or recommender systems based on argumentation, where datasets are often provided in the form of relational databases.

In 2001, W. Carnielli and Marcos considered a 3-valued logic in order to prove that the schema ϕ ∨ (ϕ → ψ) is not a theorem of da Costa’s logic Cω. In 2006, this logic was studied (and baptized) as G'3 by Osorio et al. as a tool to define semantics of logic programming. It is known that the truth-tables of G'3 have the same expressive power than the one of Łukasiewicz 3-valued logic as well as the one of Gödel (...) 3-valued logic G3. From this, the three logics coincide up-to language, taking into acccount that 1 is the only designated truth-value in these logics. -/- From the algebraic point of view, Canals-Frau and Figallo have studied the 3-valued modal implicative semilattices, where the modal operator is the well-known Moisil-Monteiro-Baaz Δ operator, and the supremum is definable from this. We prove that the subvariety obtained from this by adding a bottom element 0 is term-equivalent to the variety generated by the 3-valued algebra of G'3. The algebras of that variety are called G'3-algebras. From this result, we obtain the equations which axiomatize the variety of G'3-algebras. Moreover, we prove that this variety is semisimple, and the 3-element and the 2-element chains are the unique simple algebras of the variety. Finally an extension of G'3 to first-order languages is presented, with an algebraic semantics based on complete G'3-algebras. The corresponding soundness and completeness theorems are obtained.

In 2016, Béziau introduces a restricted notion of paraconsistency, the so-called genuine paraconsistency. A logic is genuine paraconsistent if it rejects the laws $\varphi,\neg \varphi \vdash \psi$ and $\vdash \neg (\varphi \wedge \neg \varphi)$. In that paper, the author analyzes, among the three-valued logics, which of them satisfy this property. If we consider multiple-conclusion consequence relations, the dual properties of those above-mentioned are $\vdash \varphi, \neg \varphi$ and $\neg (\varphi \vee \neg \varphi) \vdash$. We call genuine paracomplete logics those rejecting (...) the mentioned properties. We present here an analysis of the three-valued genuine paracomplete logics. A very natural twist structures semantics for these logics is also found in a systematic way. This semantics produces automatically a simple and elegant Hilbert-style characterization for all these logics. Finally, we introduce the logic LGP which is genuine paracomplete is not genuine paraconsistent, not even paraconsistent and cannot be characterized by a single finite logical matrix. (shrink)

In 2016 Beziau, introduce a more restricted concept of paraconsistency, namely the genuine paraconsistency. He calls genuine paraconsistent logic those logic rejecting φ, ¬φ |- ψ and |- ¬(φ ∧ ¬φ). In that paper the author analyzes, among the three-valued logics, which of these logics satisfy this property. If we consider multiple-conclusion consequence relations, the dual properties of those above mentioned are: |- φ, ¬φ, and ¬(ψ ∨ ¬ψ) |- . We call genuine paracomplete logics those rejecting the mentioned properties. (...) We present here an analysis of the three-valued genuine paracomplete logics. (shrink)

The literary genesis of Einbahnstraße by Walter Benjamin represents a very special case of the use of the procedures of surrealism in the philosophical-literary production of the author. The process of evolution of thinking that ended up in the writing of this piece is unveiled throughout the present analysis. This is a sign of both waiver and restart; the opening for a new productive dimension in the career of one of the most important —and misunderstood— philosophers of the 20th century. (...) More than enlightening a small master piece of philosophy from a literary perspective, or analyzing a small master piece of literature from the philosophy, what is being problematized here is the division, cultivated or figured throughout the years, between both disciplines. This work is intended to recover what is insoluble from the philosophical-literary labor of Walter Benjamin, besides tracing a possible reconfiguration for an interdisciplinary field of work to come up and contribute in the understanding of the problem called The Retreat of Metaphor by Jacques Derrida.

Sendo a fenomenologia um modo não-especulativo de pensar, o artigo põe a questão sobre a possibilidade de descrever a metafísica em regime de redução fenomenológica, ou seja, a partir de uma atitude que não pretende discursar sobre o ser enquanto ser, mas sim a partir dos diferentes “modos de aparecer” dos principais “objetos” da metafísica: alma, mundo e Deus. Neste caso, que sentido deverá possuir, para o modo fenomenológico de pensar, o metá, presente na palavra metafísica?

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

Este artículo pretende analizar la particular relación de imbricación que Michel Foucault y Giorgio Agamben han venido a establecer entre la vida humana y el poder. A tal fin, se propone un recorrido por los dos momentos centrales de su producción que permiten dar cuenta de dicha imbricación: en el caso de Agamben, el referido a la investigación “homo sacer” y, en el de Foucault, el de su investigación en torno de la biopolítica como acontecimiento decisivo de la modernidad. Ambas (...) investigaciones han redundado, entre otros aspectos, pero de manera central, en la configuración de la vida humana en su relación con el poder. En cada uno de los momentos elegidos en las producciones de los filósofos, se analizan las nociones centrales que componen cada investigación: nuda vida, “homo sacer”, estado de excepción y “oikonomía”, en el primer caso; y biopolítica y gubernamentalidad, en el segundo. Finalmente, se contrastan ambas formulaciones filosóficas a fin de sopesar los alcances y las potencialidades que implican frente al análisis que proponen. Este breve ejercicio de análisis sobre la relación entre la vida y el poder en los dos filósofos, pretende poner en evidencia los riesgos a los que nos exponen ciertos presupuestos frecuentes que fundamentan y dan sentido a las ideas y a las prácticas políticas contemporáneas.

Abstract: The Pull Bayesian Significance Test (FBST) for precise hy- potheses is applied to a Multivariate Normal Structure (MNS) model. In the FBST we compute the evidence against the precise hypothesis. This evi- dence is the probability of the Highest Relative Surprise Set (HRSS) tangent to the sub-manifold (of the parameter space) that defines the null hypothesis. The MNS model we present appears when testing equivalence conditions for genetic expression measurements, using micro-array technology.

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of QmbC, (...) the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)

Proponents of enactivism should be interested in exploring what notion of action best captures the type of action-perception link that the view proposes, such that it covers all the aspects in which our doings constitute and are constituted by our perceiving. This article proposes and defends the thesis that the notion of sensorimotor dependencies is insufficient to account for the reality of human perception, and that the central enactive notion should be that of perceptual practices. Sensorimotor enactivism is insufficient because (...) it has no traction on socially dependent perceptions, which are essential to the role and significance of perception in our lives. Since the social dimension is a central desideratum in a theory of human perception, enactivism needs a notion that accounts for such an aspect. This article sketches the main features of the Wittgenstein-inspired notion of perceptual practices as the central notion to understand perception. Perception, I claim, is properly understood as woven into a type of social practices that includes food, dance, dress, music, etc. More specifically, perceptual practices are the enactment of culturally structured, normatively rich techniques of commerce of meaningful multi- and inter-modal perceptible material. I argue that perceptual practices explain three central features of socially dependent perception: attentional focus, aspects’ saliency, and modal-specific harmony-like relations. (shrink)

In this essay I revise, based on the notion of the ‘enlightened ruler’ or mingzhu and his critique of the literati of his time, the common belief that Han Fei was an amoralist and an advocate of tyranny. Instead, I will argue that his writings are dedicated to advising those who ought to rule in order to achieve the goal of a peaceful and stable society framed by laws in accordance with the dao.

People have disagreed on the significance of Libet-style experiments for discussions about free will. In what specifically concerns free will in a libertarian sense, some argue that Libet-style experiments pose a threat to its existence by providing support to the claim that decisions are determined by unconscious brain events. Others disagree by claiming that determinism, in a sense that conflicts with libertarian free will, cannot be established by sciences other than fundamental physics. This paper rejects both positions. First, it is (...) argued that neuroscience and psychology could in principle provide support for milder deterministic claims that would also conflict with libertarian free will. Second, it is argued that Libet-style experiments—due to some of their peculiar features, ones that need not be shared by neuroscience as a whole—currently do not support such less demanding deterministic claims. The general result is that neuroscience and psychology could in principle... (shrink)

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces naturally a (...) non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

From Gadamer's Habilitation thesis, “Plato’s dialectical ethics. Phenomenological Interpretations Relating to the Philebus” (1928), this article seeks to highlight the fundamental lines of Plato’s image, outlined in that author’s first philosophical publication (1931). The confrontation with the themes of ethics and dialectic, in the current state of Platonic studies, indicates that in Plato’s image drawn in the early confrontation with the Philebus, clearly influenced by the phenomenological notion of Dasein, one already finds the fundamental features of what will become Gadamer's (...) philosophical hermeneutics, fully emancipated from Heideggerian tutelage.

The aim of the paper is to analyze the expressive power of the square operator of Łukasiewicz logic: ∗x=x⊙x⁠, where ⊙ is the strong Łukasiewicz conjunction. In particular, we aim at understanding and characterizing those cases in which the square operator is enough to construct a finite MV-chain from a finite totally ordered set endowed with an involutive negation. The first of our main results shows that, indeed, the whole structure of MV-chain can be reconstructed from the involution and the (...) Łukasiewicz square operator if and only if the obtained structure has only trivial subalgebras and, equivalently, if and only if the cardinality of the starting chain is of the form n+1 where n belongs to a class of prime numbers that we fully characterize. Secondly, we axiomatize the algebraizable matrix logic whose semantics is given by the variety generated by a finite totally ordered set endowed with an involutive negation and Łukasiewicz square operator. Finally, we propose an alternative way to account for Łukasiewicz square operator on involutive Gödel chains. In this setting, we show that such an operator can be captured by a rather intuitive set of equations. (shrink)

It is commonly accepted that Han Fei studied under Xunzi sometime during the late third century BCE. However, there is surprisingly little dedicated to the in-depth study of the relationship between Xunzi’s ideas and one of his best-known followers. In this essay I argue that Han Fei’s notion of xing, commonly translated as human nature, was not only influenced by Xunzi but also that it is an important feature of his political philosophy.

In the current debate in political philosophy, the so-called communitarian thinkers intend to offer an alternative to the dominant liberal thought. The ideal of ethicalcommunity as way of life in society in which intersubjective relationships are ruled by laws conceived as public laws, reintroduces the question of virtue in the scope of social and political life, with the requirement of an ethical style of doing politics.

Judging a person as morally responsible involves believing that certain responses (such as punishment, reward, or expressions of blame or praise) can be justifiably directed at the person. This paper develops an account of the evolution of moral responsibility judgment that adopts Michael Tomasello’s two-step theory of the evolution of morality and borrows also from Christopher Boehm’s work. The main hypothesis defended is that moral responsibility judgment originally evolved as an adaptation that enabled groups of cooperative individuals to hold free (...) riders responsible more safely by acting in a coordinated way.

I argue that Husserl’s concept of position-taking, Stellungnahme, is adequate to understand the idea of second nature as an issue of philosophical anthropology. I claim that the methodological focus must be the living subject that acts and lives among others, and that the notion of second nature must respond to precisely this fundamental active character of subjectivity. The appropriate concept should satisfy two additional desiderata. First, it should be able to develop alongside the biological, psychological, and social individual development. Second, (...) it should be able to underlie the vast diversity of human beings within and across communities. As possible candidates, I contrast position-taking with two types of habit-like concepts: instinct and habitus, on the one hand, and customary habits, on the other. I argue that position-taking represents the active aspect of the subject while the habit-like concepts are passive. A subject’s position-takings and ensuing comportments are tied together by motivations, which evince a certain consistency, and for this reason are expression of the subject’s identity. I conclude by nuancing the relation between Stellungnahme and passivity. Passivity is deemed necessary to action but subservient to it; position-taking is thought to be prior to passivity. (shrink)

Although vaccines are considered an efficient public health tool by medical experts, in different countries, people’s confidence in them has been decreasing. COVID-19 has elevated medical scientists’ and practitioners’ social reputation, and it may have reduced global vaccination hesitancy. Still, this alone will not altogether remove the existent frictions that prevent people from complying with vaccination schedules. This paper will review the common causes behind vaccination hesitancy. It will also explore different types of public policy interventions that health experts in (...) governments and institutions employ to fight vaccine hesitancy and non-compliance. The main objective of this article is to argue that, considering the nature of the issue (vaccine hesitancy and its causes), among the various possibilities, policies based on behavioral insights can provide an effective instrument to remove those frictions. Among them, special attention will be devoted to nudges which promise efficiency while avoiding some of the ethical and political costs of other interventions, thanks to their libertarian paternalistic frame. The article concludes by suggesting that public health policymakers should consider the libertarian paternalistic approach of nudges when deploying interventions that aim at changing people’s attitudes and behavior.

In a previous paper, I argued that neuroscience and psychology could in principle undermine libertarian free will by providing support for a subset of what I called “statements of local determination.” I also argued that Libet-style experiments have not so far supported statements of that sort.

Here, I explain why I still disagree with their (...) conclusion, despite being sympathetic to a lot of what they say in support of it. (shrink)

This article faces the classic problem of the interpretation of what Aristotle calls in de An. III, 5 “the intellect that produces all things”, which is commonly named agent intellect. Historically, there have been two approaches: one that goes back to Alexander of Aphrodisias, who associates the agent intellect with the unmoved mover and the divinity, and another one, associated with Theophrastus but whose major representatives are Philoponus and St. Thomas of Aquinas, who consider that agent intellect is an exclusively (...) human faculty. This last interpretation has been the most accepted historically. Nevertheless, in recent years there has been a resurgence of interpretations of the agent intellect as divine (Caston, Frede, Burnyeat, and others). What we want to demonstrate in this article is that this revival, more than responding to a reinterpretation of the agent intellect, is due to a different understanding of the divinity in Aristotle’s philosophy, which supposes immanent characteristics closer to the human intellect.

The dissertation has two parts, each dealing with a problem, namely: 1) What is the most adequate account of fuzziness -the so-called phenomenon of vagueness?, and 2) what is the most plausible solution to the sorites, or heap paradox? I will try to show that fuzzy properties are those which are gradual, amenable to be possessed in a greater or smaller extent. Acknowledgement of degrees in the instantiation of a property allows for a gradual transition from one opposite to the (...) other, each intermediate stage constituting an overlap in certain proportion of both contraries. Hence, degrees in the possession of a property give rise to simple contradictions. The reason why I have chosen those two questions is that they provide the main philosophical motivation for a particular brand of an infinite valued and paraconsistent logic. I will claim that Classical logic (CL) is not adequate to handle fuzzy situations, and, being deficient, is in need of being expanded to make room for degrees of truth and weak contradictions. One can hardly deny the importance of the debate, since what is ultimately at stake is what the limits of truth, rationality, intelligibility and possibility are. The main disciplines within which the research moves are the philosophy of language, philosophy of logic, and ontology. (shrink)

Cultural evolution is normally framed in informational terms. However, it is not clear whether this is an adequate way to model cultural evolutionary phenomena and what, precisely, “information” is supposed to mean in this context. Would cultural evolutionary theory benefit from a well-developed theory of cultural information? The prevailing sentiment is that, in contradistinction to biology, informational language should be used nontechnically in this context for descriptive, but not explanatory, purposes. Against this view, this article makes the case for the (...) need to take a proper biology-based “informational turn” in the cultural evolutionary sciences. I argue that the current vague use of informational language misses out on the potential benefits for advancing understanding of phenomena that information-theoretic reasoning has provided in other sciences, especially genetics. In particular, by emphasizing the informational aspects of cultural evolutionary processes, this approach can clarify some conceptual and methodological problems that have plagued cultural evolutionary theory since its inception, including (1) how to determine the channel conditions of cultural information flow, (2) the nature and scope of cultural information, and (3) how to quantify trends of cultural cumulation. More generally, theories of cultural evolution will be incomplete until the mechanisms underlying cultural processes are better understood and integrated into the explanations. This article explores the adequacy of an information-theoretic framework to accomplish these purposes. (shrink)

Consequently, I shall defend an Intermediate State and I shall propose briefly one metaphysical conception of the human being able to reply to Turner (...) Jr’s objections. (shrink)

This paper focuses on Gilberto Gomes’ work on free will. In a series of contributions that have had a significant impact on the respective literature, Gomes developed a conception about free will and argued that its existence is consistent with recent scientific findings, specially in neuroscience. In this paper, I object to a claim of Gomes about his conception of free will, namely the claim that it is a compatibilist conception. I seek to show that Gomes does not use the (...) term ‘compatibilism’ as it is usual in the contemporary literature on free will, i.e., as the thesis that free will can exist even if determinism is true. Moreover, the conception of free will Gomes proposes actually has an incompatibilist commitment. I argue that, more than a mere terminological point, acknowledging the incompatibilist aspect of Gomes’ view motivates important questions about the details of the view and helps to reveal a limitation of his defense of the existence of free will. [Este artigo tem como tema o trabalho de Gilberto Gomes sobre o livre-arbítrio.

Argumento que, mais do que uma mera elucidação terminológica, reconhecer o elemento incompatibilista presente na proposta de Gomes suscita questões importantes sobre os detalhes da proposta e também ajuda a reconhecer uma limitação de sua defesa da existência do livre-arbítrio.].

In abstract algebraic logic, many systems, such as those paraconsistent logics taking inspiration from da Costa's hierarchy, are not algebraizable by even the broadest standard methodologies, as that of Blok and Pigozzi. However, these logics can be semantically characterized by means of non-deterministic algebraic structures such as Nmatrices, RNmatrices and swap structures. These structures are based on multialgebras, which generalize algebras by allowing the result of an operation to assume a non-empty set of values. This leads to an interest in (...) exploring the foundations of multialgebras applied to the study of logic systems. -/- It is well known from universal algebra that, for every signature Sigma, there exist algebras over Sigma which are absolutely free, meaning that they do not satisfy any identities or, alternatively, satisfy the universal mapping property for the class of Sigma-algebras. Furthermore, once we fix a cardinality of the generating set, they are, up to isomorphisms, unique, and equal to algebras of terms (or propositional formulas, in the context of logic). Equivalently, the forgetful functor, from the category of Sigma-algebras to Set, has a left adjoint. This result does not extend to multialgebras. Not only multialgebras satisfying the universal mapping property do not exist, but the forgetful functor U, from the category of Sigma-multialgebras to Set, does not have a left adjoint. -/- In this paper we generalize, in a natural way, algebras of terms to multialgebras of terms, whose family of submultialgebras enjoys many properties of the former. One example is that, to every pair consisting of a function, from a submultialgebra of a multialgebra of terms to another multialgebra, and a collection of choices (which selects how a homomorphism approaches indeterminacies), there corresponds a unique homomorphism, what resembles the universal mapping property. Another example is that the multialgebras of terms are generated by a set that may be viewed as a strong basis, which we call the ground of the multialgebra. Submultialgebras of multialgebras of terms are what we call weakly free multialgebras. Finally, with these definitions at hand, we offer a simple proof that multialgebras with the universal mapping property for the class of all multialgebras do not exist and that U does not have a left adjoint.

In the last few decades, the literature on moral responsibility has been increasingly populated by scientific studies. Studies in neuroscience and psychology, in particular, have been claimed to be relevant for discussions about moral responsibility in a number of ways. And at the same time, there is not yet a systematic understanding of the sort of questions a science of moral responsibility is supposed to answer. This paper is an attempt to move toward such an understanding. I discuss three models (...) for framing scientific questions relevant to an investigation of moral responsibility. The favored model—the Enhancement model—proposes that a science of moral responsibility has two descriptive tasks. First, science can describe the causes and effects of the many sorts of responses that constitute the human practices of moral responsibility, such as praise, blame, and punishment. And, second, science can describe how modifications aiming at the improvement of such practices can be achieved. Relatively to the other models to be considered, the Enhancement model is broader in scope and less tied to the traditional philosophical agenda on moral responsibility. (shrink)

Resumo: Em décadas recentes, a investigação filosófica sobre a responsabilidade moral e o livre-arbítrio, que por muito tempo foi vista como um empreendimento principalmente teórico, passou a também incluir preocupações de tipo mais prático. Essa mudança é bem ilustrada pela proposta cética desenvolvida por autores como Derk Pereboom e Gregg Caruso. Seus trabalhos não apenas negam que sejamos agentes livres e moralmente responsáveis (em um sentido específico dos termos em questão), mas também defendem reformas na maneira como a responsabilização é (...) efetivada em nossas relações interpessoais e, especialmente, no sistema penal. Este artigo examina as implicações práticas do ceticismo de Pereboom e Caruso, principalmente no que diz respeito à sua implementabilidade. Argumento que o núcleo propriamente cético da proposta é inviável para seres humanos com a psicologia moral que temos, mas que, apesar disso, alguns elementos da proposta são compatíveis com uma proposta não-cética focada no aperfeiçoamento das práticas punitivas. Abstract: In recent decades, the philosophical investigation of moral responsibility and free will, which for a long time was seen as a mostly theoretical enterprise, became also the place of more practically oriented concerns. The skeptical view developed by Derk Pereboom and Gregg Caruso is a good illustration of the change. In their work, they not just deny that we are free and morally responsible agents (in a specific sense of the relevant terms) but also propose the reform of responsibility practices as they figure in our interpersonal relations and, especially, in the criminal justice system. This paper examines the practical implications of Pereboom and Caruso’s skepticism, particularly in what concerns its likelihood of being implemented. I argue that the strictly skeptical core of their proposal is not viable for human beings with a moral psychology like ours, but that some elements are nonetheless consistent with a non-skeptical view focused on the improvement of punitive practices.

This article covers the different stages of the constitution of the person that goes beyond selfishness and self-affirmation and is formed as the inseparable unity of the metaphysical subject that is expressed in the "Other-in-the same" and "Being-for-the-other".

This relationship, considered internally as a footprint, and in the exterior as visage, invokes a third party that establishes (...) and holds it. The person is shown as an asymmetrical relationship that I call triadic. (shrink)

Free will skepticism is the view that people never truly deserve to be praised, blamed, or punished for what they do. One challenge free will skeptics face is to explain how criminality could be dealt with given their skepticism. This paper critically examines the prospects of implementing legal changes concerning crime and punishment derived from the free will skeptical views developed by Derk Pereboom and Gregg Caruso. One central aspect of the changes their views require is a concern for reducing (...) the severity of current forms of punishment. The paper considers two strategies for pursuing such a reduction. By taking into account evidence from the psychology of belief in free will and desire to punish, it is argued that a strategy aiming at a reduction of people’s natural desire to punish criminals can be successful if capable of providing alternatives to current forms of punishment satisfying three properties: they must be less harmful than current forms of punishment, more effective in preventing crime, and incompatible with current forms of punishment.

Many think that expressivists have a special problem with negation. I disagree. For if there is a problem with negation, I argue, it is a problem shared by those who accept some plausible claims about the nature of intentionality. Whether there is any special problem for expressivists turns, I will argue, on whether facts about what truth-conditions beliefs have can explain facts about basic inferential relations among those beliefs. And I will suggest that the answer to this last question is, (...) on most plausible attempts at solving the problem of intentionality, ‘no’. (shrink)

What is a philosophy class like? What roles do teachers and students play? Questions like these have been answered time and again by philosophers using images and metaphors. As philosophers continue to develop pedagogical approaches in a more conscious way, it is worth evaluating traditional metaphors used to understand and structure philosophy classes. In this article, we examine two common metaphors—the sage on the stage, and philosophy as combat—and show why they fail pedagogically. Then we propose five metaphors—teaching philosophy as (...) world-traveling, wondering, conducting an orchestra, storytelling, and coaching—that can better respond to the needs of increasingly diverse student bodies. Further, these metaphors find their ground in long-standing beliefs about what philosophy is, how it is done, and what it can do for those willing to engage in it. While no single one of them is comprehensive, we think that these models can help us enliven our own thinking about our teaching and the roles we and our students play in our classrooms. (shrink)

On a view implicitly endorsed by many, a concept is epistemically better than another if and because it does a better job at ‘carving at the joints', or if the property corresponding to it is ‘more natural' than the one corresponding to another. This chapter offers an argument against this seemingly plausible thought, starting from three key observations about the way we use and evaluate concepts from en epistemic perspective: that we look for concepts that play a role in explanations (...) of things that cry out for explanation; that we evaluate not only ‘empirical' concepts, but also mathematical and perhaps moral concepts from an epistemic perspective; and that there is much more complexity to the concept/property relation than the natural thought seems to presuppose. These observations, it is argued, rule out giving a theory of conceptual evaluation that is a corollary of a metaphysical ranking of the relevant properties. -/- conceptual ethics, explanation, naturalness, epistemic value, concept/property, semantic internalism.

El texto pretende aportar una reflexión en torno a dos categorías teórico-prácticas –regionalidad, populismo–, que pueden contribuir a la proyección abierta, nunca acabada, de un nuevo orden post-neoliberal, en tanto modos de resistencia y crítica de los modos de subjetivación y de mercantilización que identificamos como propios del neoliberalismo en tanto racionalidad, pero también posibilitadoras de un pensar situado, propositivo, comprometido políticamente con el lugar desde donde se entiende y se proyecta un nuevo orden de convivencia.

In David Hume’s A Treatise of Human Nature, reason and passion are in constant interaction forming belief. Moral events are distinguished on three levels: moral sentiment, moral action and moral judgment, in which reason and passion interact, although with different functions at each level.

Y-a-t-il une inconsistance entre la thèse d’un Dieu chrétien et l’existence du mal ? Notre argumentation se basera sur l´excellente thèse développée par Alvin Plantinga, qui soutient, contre John L. Mackie, la consistance du théisme face au problème du mal. Cependant, nous refuserons de suivre la métaphysique modale adoptée par Alvin Plantinga et proposerons une position actualiste, et plus précisément l’essentialisme sérieux prôné par E. J. Lowe. Nous montrerons qu’il est alors possible de suivre l’argumentation logique de Plantinga tout en (...) soutenant un essentialisme sérieux. (shrink)

Los desencuentros de la filosofía latinoamericana con Nietzsche pueden entenderse como un síntoma de algo más que un problema de legibilidad o malentendido. En tanto pensamiento de lo uno, la filosofía latinoamericana (mayoritaria) no puede servirse del pensamiento nietzscheano: es imposi-ble construir un pensamiento del origen y la unidad desde un pensamiento de lo múltiple, como el de Nietzsche. La identidad, tan buscada por esa filosofía latinoamericana mayoritaria, es una ansiedad antigenealógica. En ese sentido, esa filosofía y su procedencia no (...) es solo eurocéntrica, como ya ha sido expuesto por otros comentaristas, sino reactiva, y esto vale para tres de sus tendencias principa-les: la filosofía normalizadora, la corriente historicista y la filosofía latinoamericana de la liberación. De ahí, de paso, la fascinación de dicho pensamiento con la idea de carencia —nunca hemos sido lo suficientemente civilizados—. Esto ha instaurado un cuerpo sufriente en América Latina, atrapado en la dialéctica de la víctima y el victimario. Se trata entonces de pensar con Nietzsche para intentar pensar sin resentimiento desde América Latina y sobre esta. ¿Nietzsche en América Latina? Sí, pero más allá de los estudios de recepción e influencia: Nietzsche como aquel estruendo capaz de infundirle una dimensión geológica al pensamiento. (shrink)

What would happen if one morning you wake up clumsy, as if your sense of touch were unreliable, arbitrarily on and off? And what would this clumsiness look like if we could transfer it to the moral sense? The article expounds an interesting analogy between the sense of touch, loosely construed, and the moral sense: just as a sort of consistency is necessary for the sense of touch to do its job, so it is for the moral sense to play (...) its part. Touch enables us to navigate the everyday world of coffee pots and staircases; our moral sensibility comes into play when we act or when we judge our actions and those of others, and plays a directive role in what we feel, how we feel it, and how we react to it. Taking the analogy further, I will suggest that inconsistency causes, in both cases, a certain clumsiness, and that clumsiness is linked to arbitrariness – like the person that helps others in dire need, but only does so on some rainy days.

Se comenta el artículo de Marisa Moyano y Hugo Aguilar sobre "El ensayo de interpretación continental: lecturas performativas y pensamiento identitario en ‘Ariel’ ". Ni reflejo pasivo de una realidad previa, ni palabra demiúrgica inventora de una realidad imaginada, los discursos identitarios son momentos reflexivos en una red inter-narrativa e inter-subjetiva de palabras, gestos y actos que afirman y constituyen a un grupo humano como sujeto político y cultural.
