The value of testimony as a source of knowledge has been a subject of epistemological debates. The "trust theory of testimony" suggests that human testimony is based on an affective relationship supported by social norms. However, the advent of generative artificial intelligence challenges our understanding of genuine testimony. The concept of "quasi-testimony" seeks to characterize utterances produced by non-human entities that mimic testimony but lack certain fundamental attributes. This article analyzes these issues in depth, exploring philosophical perspectives on testimony and (...) the implications of conversational AI technologies on our epistemic practices. (shrink)

'Computationalism' is a relatively vague term used to describe attempts to apply Turing's model of computation to phenomena outside its original purview: in modelling the human mind, in physics, mathematics, etc. Early versions of computationalism faced strong objections from many (and varied) quarters, from philosophers to practitioners of the aforementioned disciplines. Here we will not address the fundamental question of whether computational models are appropriate for describing some or all of the wide range of processes that they have been applied (...) to, but will focus instead on whether `renovated' versions of the \textit{new computationalism} shed any new light on or resolve previous tensions between proponents and skeptics. We find this, however, not to be the case, because the 'new computationalism' falls short by using limited versions of "traditional computation", or proposing computational models that easily fall within the scope of Turing's original model, or else proffering versions of hypercomputation with its many pitfalls.

Teacher quality, its effect on students’ outcomes, and the association of these with economic growth, is the core of recent discussions in Latin America given the region’s weak results in international learning assessments. This paper investigates whether there is an effect of philosophy on the outcomes of critical reading for students in B.Ed. programs in Colombia. Relying on exact matching combined with propensity score matching with regression adjustment, we use national data from Colombia to show that students in B.Ed. in (...) philosophy outperformed students in other B.Ed. in critical reading test (0.401–0.124 SD), and, importantly, with higher effects observed for students with lower prior academic achievement (0.44 SD). This suggests that philosophy can help to narrow educational outcomes of students whose socioeconomic conditions are disadvantageous, contributing to social justice in education. (shrink)

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)

Los sociobiólogos han defendido una posición "calvinista" que se resume en la siguiente fórmula: si la selección natural explica las actitudes morales, no hay altruismo genuino en la moral; si la moral es altruista, entonces la selección natural no puede explicarla. En este ensayo desenmascaro los presupuestos erróneos de esta posición y defiendo que el altruismo como equidad no es incompatible con la selección natural. Rechazo una concepción hobbesiana de la moral, pero sugiero su empleo en la interpretación de la (...) psicología de los primates no humanos y en un modelo de progresión evolutiva que habría llevado a la moralidad como adaptación pasando por la razón instrumental. /// Sociobiologists have endorsed a "Calvinist" position captured in the following formula: if natural selection explains moral attitudes, morality is not genuinely altruistic; if morality is altruistic, then natural selection cannot explain it. I expose the false presuppositions behind this claim and argüe that altruism as fairness is not incompatible with natural selection. I reject a Hobbesian view of morality as an instrumental endorsement of fairness norms, but suggest its use to interpret primate psychology and to model an evolutionary progression ending in moral capacities as adaptations.

A Revisão de Crenças estuda como agentes racionais mudam suas crenças ao receberem novas informações. O sistema AGM, trabalho mais influente desta área apresentado por Alchourrón, Gärdenfos e Makinson, postula critérios de racionalidade para os diferentes tipos de mudança de crenças e oferece construções explícitas para tais - a equivalência entre os postulados e operações é chamado de teroema da representação. Trabalhos recentes mostram como o paradigma AGM pode ser compatível com diferentes lógicas não-clássicas, o que é chamado de AGM-compatibilidade (...) - este é o caso da família de lógicas paraconsistentes que analisamos, as Lógicas da Inconsistência Formal (LFIs, da sigla em inglês). A despeito da AGM-compatibilidade, ao se partir de uma nova lógica sua racionalidade subjacente deve ser entendida e sua linguagem deve ser efetivamente usada. Propomos assim novas construções que de fato capturam a intuição presente na LFIs - é o que chamamos de sistema AGMo. Com isso, possibilitamos a estas lógicas uma nova interpretação, na esteira da epistemologia formal. Em uma abordagem alternativa, ao se partir da AGM-compatibilidade os resultados AGM podem ser diretamente aplicados às LFIs - o que chamamos de sistema AGMp. Em ambas abordagens, provamos os respectivos teoremas da representação sempre que necessário. (shrink)

This paper provides an interpretation of Aristotle’s criticism to the solution to Meno’s Paradox suggested by Plato. According to Aristotle, when Plato says that reminiscence (anámnēsis) is achieved, what is actually achieved is induction (epagōgê). Our interpretation is based on two aspects: (1) semantic criticism, since Plato’s use of the term anámnēsis is unusual; and (2) the theory is not able to give an adequate explanation of the effective discovery.

Dans cette étude nous nous proposons d’étudier la présence du Christ dans l’Eucharistie dans une perspective métaphysique et ontologique. Dans les deux premières sections nous définirons et montrerons qu’il faut distinguer: le problème de l’Eucharistie et la question fondamentale de l’Eucharistie. Nous défendrons la thèse selon laquelle le problème de l’Eucharistie en est vraiment un seulement pour ceux qui acceptent l’ontologie de l’aristotélisme, plus précisément celle de la transsubstantiation. Or, nous montrerons que l’ontologie de la transsubstantiation suppose des problèmes théoriques (...) insurmontables et nous suggérerons que nous devons nous intéresser plutôt à la question fondamentale de l’Eucharistie. Afin de montrer qu’il est possible de donner une réponse à la question fondamentale de l’Eucharistie, nous esquisserons une solution à partir d’une ontologie des tropes. (shrink)

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

Not only is freedom a shared concern of Sartre and Schelling, which would not be anything particularly unique, but for both philosophers, freedom must be articulated out of an ontological ground, or within the confines of an ontological system. A contradiction nevertheless appears to arise regarding the “orientation” of Sartre and Schelling’s respective “ontologies of freedom”: the freedom of Sartre, reflecting a contemporary stoic-inspired doctrine, is directed toward the future, while for Schelling, with affinities to the temporal logic of psychoanalysis, (...) freedom is oriented toward the past. This article presents both Sartre and Schelling’s ontological reasoning out of which either a progressively oriented freedom (the freedom to negate the present in the name of future “possibles”) or a retrogressively oriented freedom (the freedom to determine the ground of the present out of an indefinite, a-temporal becoming), before attempting to resolve this contradiction in the temporality of freedom by examining the position and role of the negative (of negation, contradiction, or nothingness), as either secondary or primary, within the ontology of each respective philosopher.

This paper presents an impact evaluation of the policies for teacher education programs within the framework of the National Development Plan 2014-2018. The programs were compelled to obtain high-quality accreditation, increase the credits in school practices, and the English level, among other requirements. Relying on multivariable regression, it shows that, for the year 2021, there is no association between high-quality accreditation in most modules of the Saber Pro tests, or it is negative in the global score and quantitative reasoning. In (...) a second step, using Differences–in–Differences, it evidences how the changes made by the programs had positive effects on the performance of students compared to other professional programs. The results show significant improvement in most modules of the Saber Pro test, except for the English module. The effects were homogeneous by characteristics of the students and institutions, but heterogeneous by area of knowledge, indicating that the effect is mainly due to the curricular changes of the programs.

One could argue that the use, extraction, and development of natural resources for human purposes, i.e. resource exploitation, constitutes a form of instrumentalization of the ecosystems from which these resources are derived. Moreover, that such instrumentalization may be carried out in a way that has adverse social and environmental impacts. Given that a number of ecosystems are indispensable for the satisfaction of human interests and needs, their instrumentalization may nevertheless be justified. In this context, if the amount and rate of (...) instrumentalization of ecosystems leads to their depletion, people whose well-being depends on the ecosystems’ existence may be profoundly harmed. Those instrumentalization practices and actions that lead to states of depletion are generally considered as harmful, but only to those whose interests and needs are frustrated as a result of such practices and actions. In this paper, I argue that the way in which ecosystems are instrumentalized, and not just the quantity and rate, may also cause a philosophically relevant form of harm, and not necessarily to humans: A given ecosystem may be meaningfully harmed not only when it is depleted, but also when its functioning is altered in such a way that it cannot retain core capacities it had before it was instrumentalized.

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)

Autonomy has been central to moral and political philosophy for millenia, and has been positioned as a critical aspect of both justice and wellbeing. Research in psychology supports this position, providing empirical evidence that autonomy is critical to motivation, personal growth and psychological wellness. Responsible AI will require an understanding of, and ability to effectively design for, human autonomy (rather than just machine autonomy) if it is to genuinely benefit humanity. Yet the effects on human autonomy of digital experiences are (...) neither straightforward nor consistent, and are complicated by commercial interests and tensions around compulsive overuse. This multi-layered reality requires an analysis that is itself multidimensional and that takes into account human experience at various levels of resolution. We borrow from HCI and psychological research to apply a model (“METUX”) that identifies six distinct spheres of technology experience. We demonstrate the value of the model for understanding human autonomy in a technology ethics context at multiple levels by applying it to the real-world case study of an AI-enhanced video recommender system. In the process we argue for the following three claims: 1) There are autonomy-related consequences to algorithms representing the interests of third parties, and they are not impartial and rational extensions of the self, as is often perceived; 2) Designing for autonomy is an ethical imperative critical to the future design of responsible AI; and 3) Autonomy-support must be analysed from at least six spheres of experience in order to approriately capture contradictory and downstream effects.

This is an obituary notice on Henri Lauener (1933-2002).

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.

Epistemic Utility Theory is often identified with the project of *axiology-first epistemology*—the project of vindicating norms of epistemic rationality purely in terms of epistemic value. One of the central goals of axiology-first epistemology is to provide a justification of the central norm of Bayesian epistemology, Probabilism. The first part of this paper presents a new challenge to axiology first epistemology: I argue that in order to justify Probabilism in purely axiological terms, proponents of axiology first epistemology need to justify a (...) claim about epistemic value—what I label ‘Downwards Propriety’—much stronger than any they have offered justification. The second part of this paper offers an argument that this challenge cannot be met: that there is no hope for providing a purely axiological justification of Downwards Propriety, at least given widely accepted assumptions about epistemic value.

Hegel insists that the category ‘nature’, expressed in relation to the ideal of aesthetic beauty, is not nature as such but a supplementary deviation coloured by the subjective position from which this ‘nature’ is posited. We cannot distinguish nature ‘in itself’ from the ideological-artistic conditions of the distorted ‘use’ of nature. Nature exists to us only by reference to what is subjectively treated as non-natural. A similar relation is posited by Lacan in his famous assertion that ‘there is no sexual (...) relation’. For Freud and Lacan, the ‘all too human’ sexual drive derives from a deviated/distorted enjoyment of the initial failure to enjoy a purely natural sexual relation: an inevitably castrated enjoyment, where ‘natural’ sexuality is revealed as impossible. In other words, sexuality is for Lacan and Freud its own distortion of the category of ‘natural’. Sexuality is a perpetually distorted and abnormal form of enjoyment, for which the alternative is not ‘normal/natural enjoyment’, but rather the negative state of a fundamental lack of any relation. Through Hegel and sexuality, this paper argues that the unavoidable misuse of nature is not caused by improper application/categorisation, but instead reflects an internal incompleteness or indeterminacy in nature as a category.

Revision operation is the consistent expansion of a theory by a new belief-representing sentence. We consider that in a paraconsistent setting this desideratum can be accomplished in at least three distinct ways: the output of a revision operation should be either non-trivial or non-contradictory (in general or relative to the new belief). In this paper those distinctions will be explored in the constructive level by showing how the remainder sets could be refined, capturing the key concepts of paraconsistency in a (...) dynamical scenario. These are preliminaries results of a wider project on Paraconsistent Belief Change conduced by the authors. (shrink)

This paper critically explores the ethical dimensions of Behavioral Public Policy (BPP), a domain grounded in the understanding that human rationality is bounded and that this limitation often leads to behaviors deemed irrational. By applying the behavioral lens, which posits that people operate under bounded rationality, BPP aims to craft interventions that safeguard individuals against their biases. However, this approach raises significant ethical concerns, both in the scientific underpinnings of BPP and its application through policy interventions. Accordingly, this paper examines (...) two distinct ethical dimensions of BPP, both as a scientific discipline and through its intervention methodologies. The analysis of the first dimension argues that, viewing bounded rationality as only instrumental in decision-making processes, risks oversimplifying ethical complexities. Such simplification may ignore the moral and value-based rationalities underlying decisions, potentially misattributing instances of immorality and akrasia (the failure to act according to one's judgment) to mere deficiencies in rational thinking. Secondly, the paper examines the impact of BPP on moral behavior and character development, addressing ethical concerns like the evidentiary basis of BPP research, the bounded rationality of choice architects themselves, and the morality of behavior changes induced by policy. Overall, this article provides a much-needed examination of the moral considerations associated with behavioral strategies in public policy and its epistemological foundations, contributing to a more comprehensive understanding of their ethical implications .

The debate about the definition of Latinidad as a social identity has fluctuated between accounts that put it closer to ethnicity or closer to race. We present and defend the claim that the multiplicity of features and experiences of Latinxs in the United States is best accounted for by placing Latinidad in a different theoretical space. We draw from the ecological psychology and enactive literature on affordances to argue that Latinidad can be better understood as a social identity affordance: a (...) multifaceted landscape of possibilities for interaction, to do and to be done unto. We then focus on four areas that are part of the objective factors that have come to constitute Latinidad and which provide reasons to shy away from both race and ethnicity: the facts of mestizaje and hybridization, a vexed relation to the land, the political horizons and histories of this population, and the multiplicity of sensory-based cultural practices of Latinxs. It is precisely the many and deep variations across Latinxs that make social affordances an apt way to conceptualize a social identity whose reality is asserted pragmatically in many aspects of social life in the U.S. (shrink)

Since the concept of “nudge” was introduced in 2008 by Thaler and Sunstein, proposing that small interventions based on changes in choice architectures can alter people’s behavior and make it easier for them to achieve their desired goals, the application in public policy of behavioral economics has gained significant attention. This has led to the emergence of different types of policies based on behavioral insights, which have been used in a variety of areas, including health or finance, with the goal (...) of promoting well-being and addressing social and economic issues. After providing a basic theoretical background as a frame of reference to understand gender violence, this study explores the use of tools from the field of behavioral economics as it is applied in public policy. Regulatory (paternalistic) and non-regulatory (libertarian) interventions based on behavioral insights will be considered: nudges, boosts, shoves, budges, or sludge audits, are examined as potential interventions to use in matters related to this type of violence. After evaluating these behavioral policy instruments and their potential effectiveness, the limitations of the behavioral perspective are recognized, and the need for a multifaceted approach to combating gender violence is acknowledged. The article concludes by arguing that public policies addressing gender violence should not only utilize behavioral tools but should also incorporate strategies related to education, legislation, and social norms.

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.

In line with recent efforts to empirically study the folk concept of weakness of will, we examine two issues in this paper: (1) How is weakness of will attribution [WWA] influenced by an agent’s violations of best judgment and/or resolution, and by the moral valence of the agent’s action? (2) Do any of these influences depend on the cognitive dispositions of the judging individual? We implemented a factorial 2x2x2 between–subjects design with judgment violation, resolution violation, and action valence as independent (...) variables, and measured participants’ cognitive dispositions using Frederick’s Cognitive Reflection Test [CRT]. We conclude that intuitive and reflective individuals have two different concepts of weakness of will. The study supports this claim by showing that: a) the WWA of intuitive subjects is influenced by the action’s (and probably also the commitment’s) moral valence, while the WWA of reflective subjects is not; b) judgment violation plays a small role in the WWA of intuitive subjects, while reflective subjects treat resolution violation as the only relevant trait. Data were collected among students at two different universities. All subjects (N=710) answered the CRT. A three-way ANOVA was first conducted on the whole sample and then on the intuitive and reflective groups separately. This study suggests that differences in cognitive dispositions can significantly impact the folk understanding of philosophical concepts, and thus suggests that analysis of folk concepts should take cognitive dispositions into account.

The purpose of this essay is to articulate a specific desideratum for any theory of Latinidad, namely, that there is no adequate conception of Latinx without an attendant conception of Afro-Latinx. In order to be reflective of those whom it purports to describe in the U.S. and elsewhere in the hemisphere, the term Latinx must be plastic enough to encompass the many internal differences, and even antagonisms, between its different constituent parts. Within it, we argue here in particular, it must (...) include its Afro-descended history, which includes not just African-descended people but also a denial of the influences of African-descended culture writ large. Our central claim here, then, is that a certain African-descendedness is constitutive of Latinidad in multiple registers, including history, cultural practices, and social identificatory processes despite Latinidad’s pernicious exclusionary history.

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)

In his comment, McGann argues that in my “From Sensorimotor Dependencies to Perceptual Practices: Making Enactivism Social,” I have overlooked a group of enactivist theories that can be grouped under the participatory sense-making label. In this reply, I explain that the omission is due to the fact that such theories are not accounts of perception. It is argued that, unlike participatory sense-making, the approach of the “From Sensorimotor Dependencies to Perceptual Practices” article does not focus on the perceptual aspects of (...) things social, but on the social aspects that are constitutive of perception in general. I conclude by underscoring the central argument of the original article: that the adequate notion to make enactivism about perception social is that of “perceptual practices,” a social practices-based notion of perception.

Desde que en 2008 se introdujera el concepto de nudge en el libro Nudge, que argumentaba que las pequeñas intervenciones basadas en cambios en la arquitectura de elección pueden alterar el comportamiento de las personas y facilitarles el logro de sus objetivos deseados, el uso de la economía del comportamiento en políticas públicas ha crecido significativamente, lo que ha llevado a la aparición de diferentes intervenciones basadas en conocimientos conductuales. Estas intervenciones se han aplicado en distintas áreas de políticas públicas (...) y administrativas, incluyendo salud, finanzas, o medio ambiente, con el objetivo de promover el bienestar y abordar problemas sociales y económicos. El uso de estas aplicaciones en cuestiones relacionadas con la violencia de género ha sido con frecuencia ignorado.

Drawing on behavioral economics, nudges (policy interventions based on choice architecture) have the capacity to strategically shape policymaking, subtly guiding individual behavior by adjusting their decision environment. Applied to enhance vaccinations, boost retirement savings, or promote healthy habits, these interventions align with consensus-defined well-being. As governments adopt nudges, scholars have explored their role in fostering virtues. This paper argues that nudges have the potential to efficiently contribute to virtuous development by instilling and sustaining habits, respecting individual choice, and ensuring deliberation. (...) It introduces the concept of virtue nudges, emphasizing the alignment of habits with virtues for targeted behavioral change and the formation of morally virtuous habits. (shrink)

Este artículo presenta y defiende una concepción expresiva del mundo perceptual que depende de la intersubjetividad. En un primer momento se muestra el desarrollo del concepto de expresión en Husserl y en Merleau-Ponty. El punto central de este desarrollo es que, en contraste con la concepción tradicional del concepto de expresión que es lingüística y consiste en el manifestarse exteriormente de algo interno, se propone ahora una idea de expresión que ya no separa radicalmente lo expresado de la expresión, no (...) se concibe como traducción, y se aplica a la relación entre subjetividad y corporalidad. Para ajustar la aplicación de la expresión a la percepción, se argumenta que las apariencias perceptuales requieren de una cualificación en términos de la posición o perspectiva del sujeto que percibe. Esta “posición” o perspectiva no es únicamente espacio-temporal, sino que también es pragmática. Finalmente, se introduce la intersubjetividad, entendida pragmáticamente, a través de la idea de que hay maneras de explorar el mundo con los sentidos que son constituidas socialmente por los diferentes grupos sociales de los que hacemos parte. Se argumenta que esta concepción pragmatista, diferente a la ruta predominante en fenomenología basada en el significado como un asunto de conciencia de la experiencia, también es defendible en el terreno fenomenológico, particularmente a través de la noción husserliana de toma de posición (Stellungnahme) y la idea merleau-pontiana de las maneras de interrogar el mundo perceptualmente. -/- This article presents and defends an expressive and intersubjectively dependent conception of the perceptual world. The first section deals with the phenomenological development of the concept of expression in Husserl and Merleau-Ponty. In this development, and in contrast with the traditional conception of expression –a linguistic conception based on the external manifesting of something inner–, a new conception appears: one that doesn’t keep a hard separation between the expression and what is expressed, is not modeled after translation, and can be applied to the relationship between subjectivity and corporeality. To further precise the way expression and perception fit together, I argue that perceptual appearances require being qualified in terms of the position or perspective of the perceiving subject. This “position” or perspective is not only spatiotemporal but also pragmatic. Lastly, a pragmatically understood intersubjectivity is brought into play. I look at the fact that there are different ways of exploring the world with our senses that are socially constituted. This constitution takes places in and through the different social groups to which we belong. I argue that this pragmatist conception, while different from the dominant phenomenological understanding that takes meaning to be about the consciousness of experiences, is also defensible on phenomenological grounds. This alternative understanding finds support in Husserl’s idea of position-taking (Stellungnahme) and Merleau-Ponty’s claim that there exist different ways of interrogating the world perceptually.

For philosophy to criticize the concept of reality requires self-criticism. Throughout history many thinkers that have systematized a critique of both reality and philosophy. In this article we will analyze the Kantian and Hegelian systems by showing the failure in their respective critique to exercise sufficient self-criticism, resulting in unfinished critiques. Going a step further, Tanabe’s proposal was to plunge philosophy into a kind of «absolute disruption» that would drive thought beyond itself by means of an absolute critique in which (...) being and nothingness are seen to interpenetrate each other, thus opening up the possibility of positing absolute nothingness as «a foundation that is not a foundation.».

En el presente texto se defenderá la idea según la cual, la filosofía y el filosofar están intrínsecamente ligados. Se partirá de un caso paradigmático, el caso de la filosofía analítica. A partir de su definición,se pretenderá mostrar que las características más sobresalientes de dicha corriente están fundamentalmente ligadas al acto de filosofar.Por medio de dicho ejemplo, se desea mostrar que enseñar la filosofía consiste en enseñar a filosofar, y que por lo tanto una no puede ser separada de la (...) otra. Aprender a filosofar es entonces, aprender a ver un problema detrás de cada página de un texto filosófico, una argumentación detrás de cada problema y finalmente, una verdad detrás de cada argumentación. El precio a pagar por dicha separación es bastante alto, se podría hablar de épocas de decadencia intelectual. (shrink)

A strange dialectical reversal characterizes the oppositions which psychoanalysis posits against philosophy and neuroscience: what psychoanalysis intervenes with as a unique and missing quality of these subjects, reveals itself upon enquiry as already having been a feature of said subjects. This article first discusses the failed intervention of psychoanalysis within the perceived totalities and absolutes of German idealism. Psychoanalysis, founded on an ontological division and internal inconsistency with a retroactive logic, finds this internal contradiction already reflected within the supposed totalities (...) of Schelling and Hegel. Schelling’s “blind act,” a decision with no prior foundation that grounds an abstract identity-in-itself, appears as the counterpart to what Badiou calls the strictly “analytic act.” Hegel’s Science of Logic, in which the inconclusive interpenetration of being and nothing presupposes its own conclusion in the transitions to essence, and in which an internal incompleteness and contradiction are retroactively constitutive of the concept, similarly nullifies the intervention of psychoanalysis. Finally, precisely such a reversal is presented in neuroscience, where the constitutive contradiction of contingently functional neuronal formations in the adaptive “multiple demand” model of executive functioning repeats the contingent and self-contradicting psychoanalytic subject as being its own deference within linguistic, discursive formations.

Intellectual progress involves forming a more accurate picture of the world. But it also figuring out which concepts to use for theorizing about the world. Bayesian epistemology has had much to say about the former aspect of our cognitive lives, but little if at all about the latter.

By enriching the resources of Epistemic Utility Theory with a more expansive conception of epistemic value, I offer (...) a picture of our cognitive economy on which adopting new conceptual tools can sometimes be epistemically rational.

The debate over Plato’s “ so called unwritten doctrines”, which he communicated only to a small circle of trusted disciples, has caused a stir among philosophers in recent decades. Rafael Ferber assumes a differentiated position in this controversy. He is convinced that the unwritten doctrines did exist, but that Plato, for reasons inherent in the process of gaining knowledge, was unable to communicate these doctrines even to his closest disciples. In this book, Ferber outlines the discussion and summarizes the (...) standpoints of greatest interest. Ever since Aristotle, we have known that Plato did not put his most important teachings into writing, but instead communicated them only orally to the inner circle of his disciples. While the extant dialogues merely pass down Plato’s “exoteric” doctrines, his most important “esoteric” insights were not meant for the general public. In the meantime, the contents and the significance of Plato’s “unwritten doctrines” have become the subject of debate in philosophical circles. Fifteen years ago, at the height of the controversy over the “unwritten doctrines”, Rafael Ferber entered the fray with a small book. He proposed that Plato was also unable to communicate the “unwritten doctrines” because the highest principles (i.e. the subject of the unwritten doctrines) cannot be known through logical operations due to an epistemological paradox. Ferber’s differentiated position met with great respect and acceptance, although in individual cases it was also rejected. Ferber’s new book again presents the text of 1991, but significantly expands on it through new perspectives and an outline of the discussion it triggered. In this book, the reader learns what is meant by Plato’s unwritten doctrines and what the controversy is all about. (shrink)

A modified visual search task demonstrates that humans are very good at resuming a search after it has been momentarily interrupted. This is shown by exceptionally rapid response time to a display that reappears after a brief interruption, even when an entirely different visual display is seen during the interruption and two different visual searches are performed simultaneously. This rapid resumption depends on the stability of the visual scene and is not due to display or response anticipations. These results are (...) consistent with the existence of an iterative hypothesis-testing mechanism that compares information stored in short-term memory (the perceptual hypothesis) with information about the display (the sensory pattern). In this view, rapid resumption occurs because a hypothesis based on a previous glance of the scene can be tested very rapidly in a subsequent glance, given that the initial hypothesis-generation step has already been performed.

En los escritos de Aristóteles está frecuentemente relacionada la investigación (zethesis) con la deliberación (boulé). En el presente texto se hará una revisión de dicha relación, y se tratará de rechazar una relación meramente analógica entre investigar y deliberar, que, como se intentará mostrar, se basa fundamentalmente en una fuerte distinción entre razón teórica y razón práctica. Se tratará de probar una relación mucho más fuerte entre investigación y deliberación, mostrando que no es ni su objeto ni las habilidades racionales (...) y cognitivas lo que distingue la una de la otra, sino simplemente su finalidad: investigar es el género de la deliberación, y, por tanto, es preciso distinguir entre investigación teórica e investigación práctica o deliberación, cuyo fin, a diferencia de la investigación teórica, es hallar la manera de alcanzar un estado de cosas determinado, lo cual no depende tanto del objeto mismo, como es el caso de la teoría, sino del agente.

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of formal (...) consistency. (shrink)

This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images but (...) that “consistency should suffice for truth” (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

This book faces the problem of how is it possible to conceive Aristotelian philosophy as a way of life, and not as a discipline or profession. If there are any of his texts where this concerns are to be found, it is in his practical treatises, in which he defends a philosophy of human affairs. However, Aristotle insists on the fact that philosophy, in its greatest expression, is the first philosophy, to which the idea of contemplation seems to refer to, (...) at the end of the Nicomachean ethics. How is this tension between human and first philosophy to be understood? Which one was more important in Aristotle’s conception of the good life? What will we be claiming here is that there’s no dichotomy between active and contemplative life beyond the conceptual analysis. On the contrary, the Aristotelian proposal is that choosing between action and contemplation is impossible without appealing to philosophy itself. The intellect, in his role as ruler of life, requires contemplation to lead action, in the same way as a medical practitioner requires natural science in order to guide his deeds. (shrink)

"Paraconsistent Belief Revision Based on a Formal Consistency Operator" delves into Belief Revision—a significant area of research in Formal Philosophy that uses logic to model the ways in which human and artificial agents modify their beliefs in response to new information and examines how these changes can be considered rational. -/- Originally authored as a PhD thesis (previously published in Portuguese), this work provides a novel epistemic interpretation of Paraconsistency through Paraconsistent Belief Revision systems. It explores the concept of paraconsistency (...) from the standpoint of epistemic attitudes of acceptance and rejection. -/- This work challenges the traditional notion that accepting a new belief requires retracting its negation from the current epistemic state. The author contends that such reflexive retraction goes against the principle of informational economy, which is a crucial aspect of rationality in the context of belief change. Consequently, the phenomenon of paraconsistency is further examined from this fresh perspective of belief change, shedding light on the complexities of the Logics of Formal Inconsistency (LFIs). These LFIs provide the foundational logic, offering a comprehensive framework for understanding and implementing paraconsistent principles within belief revision systems. -/- This thesis was supervised by Marcelo Esteban Coniglio and co-supervised by Márcio Moretto Ribeiro, as part of Rafael Rodrigues Testa's doctoral studies at the University of Campinas (Unicamp), Brazil.

O propósito deste trabalho é analisar a estrutura e discutir a aplicação da(s) lógica(s) deôntica(s) na representação de normas jurídicas. Após uma apresentação desta(s) lógic(s) e, em particular, do sistema de von Wright e da SDL (Standard Deontic Logic), veremos as dificuldades de se aplicar uma lógica à análise do direito positivo: as regras da lógica devem permitir realizar sobre as normas formalizadas somente os tipos de inferência e operaçôes lógicas intuitivamente feitas pelos juristas, ou seja, a reconstrução lógica do (...) direito positivo não se trata de uma tarefa de criação do direito, mas uma tarefa de representação daquilo que o conceito de direito usual reconhece como tal. Para ilustrar estas dificuldades, abordaremos as propostas de Carlos Alchourrón em artigo de 1975, “Condicionalidad y la representación de las normas jurídicas”. (shrink)

I argue for the Cooperative Warrant Thesis (CWT), according to which the determinants of testimonial contents in communication are given by the practical requirements of cooperative action. This thesis distances itself from conventionalist views, according to which testimony must be strictly bounded by conventions of speech. CWT proves explanatorily better than conventionalism on several accounts. It offers a principled and accurate criterion to distinguish between testimonial and non-testimonial communication. In being goal-sensitive, this criterion captures the role of weak and robust (...) cooperation in determining the contents to which speakers testify or fail to testify. And, finally, it yields a principled explanation of why testimony entails the epistemic commitments that distinguish it as an epistemic source. (shrink)

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the introduction of (...) space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)
