_RESUMO:_ O presente artigo tem como objetivo indagar e talvez responder – com auxílio dos comentadores – dois pontos relevantes na lógica de Hegel. O primeiro, diz respeito à concepção de fundamentação de um sistema filosófico sem um começo: a ideia de um pressuposto incondicionado. O segundo, concerne à condiçõe das modalidades de necessidade e contingência numa lógica que se propõe absoluta. Como método absoluto, a ciência da lógica expõe o devir como condição do puro pensamento e Aufhebung [suprassunção] aparece (...) como um conceito central, pois é o motor que impulsiona a dialética. Isso pode ser observado tanto na Ciência da Lógica (2016) – com as determinações do pensamento – como na Fenomenologia do Espiríto (2018) – com as figuras da consciência –. Observa-se que há uma relação entre os conceitos de Aufhebung, necessidade e início absoluto. Por tanto, a partir dessa relação, objetiva-se expor a condição das modalidades de necessidade e contingência num sistema absolouto. (shrink)

Despite the abundance of works and debates concerning the concept of freedom, whether individual, collective or metaphysical, it is noted that the questions surrounding the topic are inexhaustible and subject to reflection. Mainly with regard to Hegel, since his philosophy does not address the concept of freedom and its consequences as isolated parts, as if there were several types of freedom. On the contrary, freedom in Hegel appears as the essence of the subjective spirit that expresses itself in the world (...) in the form of the objective spirit, that is, in history. This, in turn, appears as an action of the spirit itself through individuals. These are guided by reason progressively to the self-knowledge that freedom is an intrinsic condition for all men. Thus, the present article aims to clarify Hegel's concept of freedom from the Fundamental Lines of the Philosophy of Law (2022) and its relationship with the concept of history. (shrink)

A sociedade brasileira no que diz respeito a sua estrutura de relações sociais como conhecemos, tem início no Brasil colônia a qual a instituição de maior força era a escravagista. Nesse sentido, as formações e interações de classes da sociedade brasileira foram arregimentadas pelo racismo, sendo ele escancarado no passado, com leis e naturalização das práticas de disciminação racial, e mantendo grande influência atualmente com a utilização de “máscaras” que encontram para legitimar sua atuação na sociedade contemporânea. Nesse contexto, nos (...) últimos anos tem-se observado a atuação irregular de ações policiais no país, principalmente nas comunidades periféricas, sendo utilizada a brutalidade e a violência física e moral dos sujeitos, violando direitos humanos e fundamentais, e colocando em perigo a vida de crianças e adolescentes que residem nesses ambientes, sobretudo, as negras, reconhecendo assim a existência do racismo estrutural. Considerando que o país é democrático, e reconhecendo que os atores sociais possuem a capacidade de influenciar nas mudanças e construções de políticas capazes de discutir os fundamentos da vida pública e social, esta proposta de pesquisa tem por objetivo refletir como a brutalidade policial afeta a confiança de crianças negras no Estado democrático por meio de instituições de segurança e proteção. Trata-se de uma pesquisa de revisão bibliográfica, qualitativa e descritiva. (shrink)

The Belnap–Dunn logic is a well-known and well-studied four-valued logic, but until recently little has been known about its extensions, i.e. stronger logics in the same language, called super-Belnap logics here. We give an overview of several results on these logics which have been proved in recent works by Přenosil and Rivieccio. We present Hilbert-style axiomatizations, describe reduced matrix models, and give a description of the lattice of super-Belnap logics and its connections with graph theory. We adopt the point of (...) view ofAlgebraic Logic, exploring applications of the general theory of algebraization of logics to the super-Belnap family. In this respect we establish a number of new results, including a description of the algebraic counterparts, Leibniz filters, and strong versions of super-Belnap logics, as well as the classification of these logics within the Leibniz and Frege hierarchies.

In two often neglected passages of the Critique of Pure Reason, Kant submits that the Critique is a 'treatise' or a 'doctrine of method'. These passages are puzzling because the Critique is only cursorily concerned with identifying adequate procedures of argument for philosophy. In this book, Gabriele Gava argues that these passages point out that the Critique is the doctrine of method of metaphysics. Doctrines of method have the task of showing that a given science is indeed a science (...) because it possesses 'architectonic unity' – which happens when it realizes the 'idea' of a science. According to Gava's novel approach, the Critique establishes that metaphysics is capable of this unity, and his reading of the Critique from this perspective not only illuminates the central role of the Transcendental Doctrine of Method within it, but also clarifies the relationship between the different parts of the work.

This discussion of pride, shame, and guilt centers on the beliefs involved in the experience of any of these emotions. Through a detailed study, the author demonstrates how these beliefs are alike--in that they are all directed towards the self--and how they differ. The experience of these three emotions are illustrated by examples taken from English literature. These concrete cases supply a context for study and indicate the complexity of the situations in which these emotions usually occur.

We combined inter- and intraindividual approaches to investigate university students’ biology- and psychology-specific specific epistemic beliefs (beliefs about the nature and structure of knowledge). We expected that university students would perceive the discipline of biology as more absolute and less multiplistic than the discipline of psychology (intraindividual perspective). Furthermore, we expected students from so-called “hard” disciplines to perceive biology as more absolute and less multiplistic than students from soft disciplines (interindividual perspective). Finally, we expected that students from hard disciplines, compared (...) to their peers from soft disciplines, would perceive stronger differences between biology and psychology (combined perspective). Hypotheses were tested, using Bayes factors, in N = 938 university students from a multitude of disciplines. Results revealed that university students perceive biology as considerably more absolute and less multiplistic compared to psychology. However, the findings also suggest that there are no strong interindividual differences between students from hard and soft disciplines regarding the perception of biology. Finally, results revealed that students enrolled in harder disciplines perceive a slightly stronger difference between biology and psychology. In sum, intraindividual effects were considerably stronger, which elicits doubt that students from hard disciplines espouse a fundamentally different set of epistemic beliefs than their peers from soft disciplines.

Gabriele Taylor presents a philosophical investigation of the "ordinary" vices traditionally seen as "death to the soul": sloth, envy, avarice, pride, anger, lust, and gluttony. In the course of a richly detailed discussion of individual and interrelated vices, which complements recent work by moral philosophers on virtue, she shows why these "deadly sins" are correctly so named and grouped together.

In this paper, I distinguish three general approaches to public trust in science, which I call the individual approach, the semi-social approach, and the social approach, and critically examine their proposed solutions to what I call the problem of harmful distrust. I argue that, despite their differences, the individual and the semi-social approaches see the solution to the problem of harmful distrust as consisting primarily in trying to persuade individual citizens to trust science and that both approaches face two general (...) problems, which I call the problem of overidealizing science and the problem of overburdening citizens. I then argue that in order to avoid these problems we need to embrace a (thoroughly) social approach to public trust in science, which emphasizes the social dimensions of the reception, transmission, and uptake of scientific knowledge in society and the ways in which social forces influence both positively and negatively the trustworthiness of science.

This book presents a systematic interpretation of Charles S. Peirce’s work based on a Kantian understanding of his teleological account of thought and inquiry. Departing from readings that contrast Peirce’s treatment of purpose, end, and teleology with his early studies of Kant, Gabriele Gava instead argues that focusing on Peirce’s purposefulness as a necessary regulative condition for inquiry and semiotic processes allows for a transcendental interpretation of Peirce’s philosophical project. The author advances this interpretation through presenting original views on (...) aspects of Peirce’s thought, including: a detailed analysis of Peirce’s ‘methodeutic’ and ‘speculative rhetoric,’ as well as his ‘critical common-sensism’; a comparison between Peirce’s and James’ pragmatisms in view of the account of purposefulness Gava puts forth; and an examination of the logical relationships that order Peirce’s architectonic classification of the sciences.

This chapter explores the concepts of ethnic identity, ethnogenesis, ethnonationalism, nationalism and multiculturalism, linking them to a critical analysis of the selective revival of the past. In particular, it looks at the meanings of the concept of ethnonationalism, and at its historical origins, in terms of how it relates to the history of nation building and national culture building, which ethnonationalism represents. Drawing on comparative ethnographic analysis, the chapter examines two opposite processes; the ways in which new ethnic groups are (...) created through a selective reading of the past, and the way in which larger polities are imposed on very different ethnic groups.

Public reason liberalism is defined by the idea that laws and policies should be justifiable to each person who is subject to them. But what does it mean for reasons to be public or, in other words, suitable for this process of justification? In response to this question, Kevin Vallier has recently developed the traditional distinction between consensus and convergence public reason into a classification distinguishing three main approaches: shareability, accessibility and intelligibility. The goal of this paper is to defend (...) the accessibility approach by demonstrating its ability to strike an appealing middle course in terms of inclusivity between shareability and intelligibility. We first argue against Vallier that accessibility can exclude religious reasons from public justification. Second, we use scientific reasons as a case study to show that accessibility excludes considerably fewer reasons than shareability. Throughout the paper, we connect our discussion of accessibility to John Rawls’s model of public reason, so as to give substance to the accessibility approach and to further our understanding of Rawls’s influential model.

Philosophers have suggested that, in order to understand the particular visual state we are in during picture perception, we should focus on experimental results from vision neuroscience—in particular, on the most rigorous account of the functioning of the visual system that we have from vision neuroscience, namely, the ‘Two Visual Systems Model’. According to the initial version of this model, our visual system can be dissociated, from an anatomo-functional point of view, into two streams: a ventral stream subserving visual recognition, (...) and a dorsal stream subserving the visual guidance of action. Following this model, philosophers have suggested that, since the two streams have different functions, they represent different properties of a picture. However, the original view proposed by the ‘Two Visual Systems Model’ about the presence of a strong anatomo-functional dissociation between the two streams has recently been questioned on both philosophical and experimental grounds. Indeed, the analysis of several new pieces of evidence seems to suggest that many visual representations in our visual system, related to different tasks, are the result of a deep functional interaction between the streams. In the light of the renewed status of the ‘Two Visual Systems Model’, also our best philosophical model of picture perception should be renewed, in order to take into account a view of the process of picture perception informed by the new evidence about such interaction. Despite this, no account fulfilling this role has been offered yet. The aim of the present paper is precisely to offer such an account. It does this by suggesting that the peculiar visual state we are in during picture perception is subserved by interstream interaction. This proposal allows us to rely on a rigorous philosophical account of picture perception that is, however, also based on the most recent results from neuroscience. Unless the explanation offered in this paper is endorsed, all the recent evidence from vision neuroscience will remain unexplained under our best empirically informed philosophical theory of picture perception.

In this paper, I distinguish scientific models in three kinds on the basis of their ontological status—material models, mathematical models and fictional models, and develop and defend an account of fictional models as fictional objects—i.e. abstract objects that stand for possible concrete objects.

In this chapter, I investigate a problem for Kant’s claim that metaphysics can reach the status of science. The problem arises when one considers Kant’s account of the “architectonic unity” of metaphysics in the Architectonic of Pure Reason. Attaining architectonic unity is a condition for becoming a science for any body of cognitions that purports to be such. This is achieved when the cognitions belonging to a science are systematically organized according to the “idea of reason” which lies at the (...) basis of that science. However, Kant suggests that nobody can ever legitimately claim to have matched the idea of the philosopher, where this appears to imply that nobody can justifiably claim that she has fully grasped the idea of metaphysics. This generates a problem. I suggest that when Kant claims that the idea of the philosopher must remain an ideal or an archetype, he has a particular conception of philosophy in mind, that is, philosophy as a doctrine of wisdom. According to this understanding, philosophy must provide an example of how one can become virtuous. However, this is only a partial solution to our problem, for reasons that will be illustrated.

This paper explores the socio-epistemic practice of shopping for experts. I argue that expert shopping is particularly likely to occur on what Thi Nguyen calls cognitive islands. To support my argument, I focus on macroeconomics. First, I make a prima-facie case for thinking that macroeconomics is a cognitive island. Then, I argue that ordinary people are particularly likely to engage in expert shopping when it comes to macroeconomic matters. In particular, I distinguish between two kinds of expert shopping, which I (...) call cynical and wishful, and introduce the notion of assisted expert shopping, which occurs when people or organizations shop for experts on behalf of other people. I argue that assisted expert shopping can sometime result in what I call a propagandistic use of expertise. Finally, I critically examine some possible reasons for optimism and find them wanting. I conclude by suggesting that that much of what I said about shopping for macroeconomic experts might also apply mutatis mutandis to other policy-relevant domains of expertise. (shrink)

In this article, we propose a new account concerning the interlock between intentions and motor representations (henceforth: MRs), showing that the interface problem is not as deep as previously proposed. Before discussing our view, in the first section we report the ideas developed in the literature by those who have tried to solve this puzzle before us. The article proceeds as follows. In Sections 2 and 3, we address the views by Butterfill and Sinigaglia, and Mylopoulos and Pacherie, respectively, and (...) argue that both solutions entail a translation between representational formats, which both accounts aim to avoid. In Section 4, we present our brand‐new claim, according to which intentions and MRs partially share the same motor format, inasmuch as executable action concepts are naturally represented in the agent's motor system together with the action's outcomes. Indeed, since intentions are constituted by executable action concepts and since there is evidence that action concepts are represented (and, thus, built) in the same motor format as action outcomes, the interlock between intentions and MRs no longer constitutes a problem. Then, in Section 5, we report empirical evidence in support of our claim, and before concluding, in Section 6 we briefly clarify our relations with two very recent accounts that criticized the proposals by Mylopoulos and Pacherie and Butterfill and Sinigaglia: Shepherd's and Burnston's. Finally, in Section 7, we offer some remarks about the philosophical idea defended here. The basic insight is that interface without translation is possible because action concepts are such stuff as MRs are made on. (shrink)

Kant’s account of practical justification for belief has attracted much attention in the literature, especially in recent years. In this context, scholars have generally emphasized the originality of Kant’s thought about belief (Glaube), and Kant indeed offers a definition of belief that is very different from views that were prevalent in eighteenth-century Germany. In this article, however, I argue that it is very likely that Christian August Crusius exerted influence on Kant’s definition of belief and his account of practical justification. (...) In turn, acknowledging this influence has relevant consequences for how we understand the phenomenology of Kantian belief. (shrink)

The most important question concerning picture perception is: what perceptual state are we in when we see an object in a picture? In order to answer this question, philosophers have used the results of the two visual systems model, according to which our visual system can be divided into two streams, a ventral stream for object recognition, allowing one to perceive from an allocentric frame of reference, and a dorsal stream for visually guided motor interaction, thus allowing one to perceive (...) from an egocentric frame of reference. Following this model, philosophers denied that we can be in a dorsal perceptual state when perceiving a depicted object. This is because a depicted object is not physically graspable or manipulable and, in turn, it cannot be egocentrically localized, as a normal object, by the dorsal stream. Thus, the impossibility of manipulating depicted objects and of localizing them from an egocentric frame of reference has led some people to be sceptical about the possibility of a representation of action properties in the perception of objects in pictures, which pertains to the dorsal visual system. The aim of the present paper is to show that it is possible for the depicted object to be represented by dorsal perception. That means that we can ascribe action properties to depicted objects as well, even if depicted objects cannot be egocentrically localized—at least, not as much as normal objects can. (shrink)

The problem of absolute generality has attracted much attention in recent philosophy. Agustin Rayo and Gabriel Uzquiano have assembled a distinguished team of contributors to write new essays on the topic. They investigate the question of whether it is possible to attain absolute generality in thought and language and the ramifications of this question in the philosophy of logic and mathematics.

Both in his pre-critical writings and in his critical works, Kant criticizes the Wolffian tradition for its use of the mathematical method in philosophy. The chapter argues that the apparent unambiguousness of this opposition between Kant and Wolff notwithstanding, the problem of ascertaining the relationship between Kant’s and Wolff’s methods in philosophy cannot be dismissed so quickly. Only a close consideration of Kant’s different remarks on Wolff’s approach and a comparison of the methods that Wolff and Kant actually used in (...) philosophy can allow us to determine when Kant’s criticisms are justified and where the differences in their methodological proposals for philosophy actually lie. We see that Kant’s account of philosophical method in fact has some elements in common with the Wolffian paradigm, even though there are also relevant differences. (shrink)

In this paper, I distinguish between two varieties of actualism—hardcore actualism and softcore actualism—and I critically discuss Ross Cameron’s recent arguments for preferring a softcore actualist account of the truthmakers for modal truths over hardcore actualist ones. In the process, I offer some arguments for preferring the hardcore actualist account of modal truthmakers over the softcore actualist one.

This paper explores the debate between those philosophers who take (fundamental, perfectly natural) properties to be pure powers and those who take them to be powerful qualities. I first consider two challenges for the view that properties are powerful qualities, which I call, respectively, ‘the clarification challenge’ and ‘the explanatory challenge’. I then examine a number of arguments that aim to show that properties cannot be pure powers and find them all wanting. Finally, I sketch what I take to be (...) the most promising argument against pure powers and for powerful qualities. (shrink)

Developing and implementing artificial intelligence (AI) systems in an ethical manner faces several challenges specific to the kind of technology at hand, including ensuring that decision-making systems making use of machine learning are just, fair, and intelligible, and are aligned with our human values. Given that values vary across cultures, an additional ethical challenge is to ensure that these AI systems are not developed according to some unquestioned but questionable assumption of universal norms but are in fact compatible with the (...) societies in which they operate. This is particularly pertinent for AI research and implementation across Africa, a ground where AI systems are and will be used but also a place with a history of imposition of outside values. In this paper, we thus critically examine one proposal for ensuring that decision-making systems are just, fair, and intelligible—that we adopt a principle of explicability to generate specific recommendations—to assess whether the principle should be adopted in an African research context. We argue that a principle of explicability not only can contribute to responsible and thoughtful development of AI that is sensitive to African interests and values, but can also advance tackling some of the computational challenges in machine learning research. In this way, the motivation for ensuring that a machine learning-based system is just, fair, and intelligible is not only to meet ethical requirements, but also to make effective progress in the field itself.

Interpretations of Kant’s account of the forms of “taking-to-be-true” (Fürwahrhalten) have generally focused on three such forms: opinion (Meinung), belief (Glaube), and knowledge (Wissen). A second distinction that has received comparatively less attention is that between conviction (Überzeugung) and persuasion (Überredung). Kant appears to use the distinction between the subjective and the objective sufficiency of a taking-to-be-true to characterize all of these forms. However, it is impossible to account for the differences between them by relying on this latter distinction alone. (...) In turn, this makes it difficult to fit all of these forms into a single classification of taking-to-be-true. In this chapter, I propose a new approach to conviction and persuasion that dissolves these problems. Conviction and persuasion are not single forms of taking-to-be-true with distinctive characteristics, yet it is not useful to treat them as “classes” of taking-to-be-true either. Rather, they are “operators” that determine whether a taking-to-be-true is apt or inapt, depending on whether it rests on a correct evaluation of the grounds we have. (shrink)

Molyneux’s question famously asks about whether a newly sighted subject might immediately recognize, by sight alone, shapes that were already familiar to her from a tactile point of view. This paper addresses three crucial points concerning this puzzle. First, the presence of two different questions: the classic one concerning visual recognition and another one concerning vision-for-action. Second, the explicit distinction, reported in the literature, between ocular and cortical blindness. Third, the importance of making reference to our best neuroscientific account on (...) vision, ‘the two visual systems model’, in order to better address Molyneux’s problem. Then, by offering a new, deeper analysis of the relation between, and, this paper suggests that the subjects of Molyneux’s two different questions show the same visual impairment as brain-damaged subjects with different lesions of the visual cortex. In particular, the subject of the first question shows the same impairment in visual recognition as a visual agnosic subject, while the subject of the second question shows the same visual impairment in visuomotor processing as an optic ataxic subject. These impairments still hold even if ocular processing is restored. Therefore, I suggest the following. For the first classic question, the required experimental setting cannot be properly reached. By contrast, concerning the second question, based on the interpretation we select, either the answer is negative, or, as with the first question, the experimental setting cannot be properly reached. This proposal constitutes, with the other approaches offered in the literature, a further attempt to tackle the enormous complexity of Molyneux’s puzzle. (shrink)

ABSTRACT:Are face-to-face perception and picture perception different perceptual phenomena? The question is controversial. On the one hand, philosophers have offered several solid arguments showing that, despite some resemblances, they are quite different perceptual phenomena and that pictures are special objects of perception. On the other hand, neuroscientists routinely use pictures in experimental settings as substitutes for normal objects, and this practice is successful in explaining how the human visual system works. But this seems to imply that face-to-face perception and picture (...) perception are very similar, if not actually the same. How can we decide between these two opposite intuitions? Here I offer a regimentation of the notion of picture perception that can reconcile these two apparently conflicting ideas about pictures. It follows that philosophers and neuroscientists can maintain their respective stances without any theoretical conflict. (shrink)

Here is a crucial question in the contemporary philosophy of perception: how can we be aware of action properties? According to the perceptual view, we consciously see them: they are present in our visual phenomenology. However, this view faces some problems. First, I review these problems. Then, I propose an alternative view, according to which we are aware of action properties because we imagine them through a special form of imagery, which I call visuomotor imagery. My account is to be (...) preferred as it offers an explanation of our awareness of action properties without generating all the problems that the perceptual view faces. (shrink)

Intellectualists suggest that practical knowledge, or ‘knowing- how’, can be reduced to propositional knowledge, or ‘knowing-that’. Anti-intellectualists, on the contrary, suggest, following the original insights by Ryle, that such a reduction is not possible. Rejection of intellectualism can be proposed either by offering purely philosophical analytical arguments, or by recruiting empirical evidence from cognitive science about the nature of the mental representations involved in these two forms of knowledge. In this paper, I couple these two strategies in order to analyze (...) some crucial reasons for which intellectualism seems not to be the best theory we have to correctly understand and describe practical knowledge. In particular, I will start from a specific philosophical account against intellectualism offered by Dickie :737–745, 2012), and suggest that it can be supported by current experimental results coming from motor neuroscience. The claim of the paper is that there is at least one kind of practical knowledge, which I call motor knowledge, and which is at the basis of the performance of skilled action, which cannot be reduced to propositional knowledge.

In a recent paper, ‘Peripersonal perception in action’ (Synthese, 2018), Frédérique de Vignemont tackles the problem of defining what is peculiar to the visual perception of objects falling within the peripersonal space of the observer, i.e. the space immediately surrounding the body, and which is commonly described as the space in which action takes place. In this paper, I first discuss the proposal offered by de Vignemont about what characterizes peripersonal perception. Then, I suggest an extension of this account that (...) offers a meticulous description of the nature of the Content of Peripersonal Visual Experience - a topic never explicitly considered in the philosophical literature on vision - by discussing some peculiar features of it that, as recognized also by de Vignemont’s account, still need to be explained. In particular, I offer a philosophical examination of the specificity of peripersonal visual experience, in relation to its phenomenological dimension, its optical mechanisms and its neurophysiological underpinnings, in the light of our best theories from vision science, and in comparison to the visual experience of other visual spaces.

My two daughters would love to go tobogganing down the hill by themselves, but they are just toddlers and I am an apprehensive parent, so, before letting them do so, I want to ensure that the toboggan won’t go too fast. But how fast will it go? One way to try to answer this question would be to tackle the problem head on. Since my daughters and their toboggan are initially at rest, according to classical mechanics, their final velocity will (...) be determined by the forces they will be subjected to between the moment the toboggan will be released at the top of the hill and the moment it will reach its highest speed. The problem is that, throughout their downhill journey, my daughters and the toboggan will be subjected to an incredibly large number of forces—from the gravitational pull of any massive object in the universe to the weight of the snowflake that is sitting on the tip of one of my youngest daughter’s hairs—so that any attempt to apply the theory directly to the real-world system in all its complexity seems to be doomed to failure.

Neste artigo, meu objetivo é analisar de que maneira o cientista, no âmbito das Ciências Naturais, é educado para assimilar, aplicar e articular um determinado paradigma na solução dos problemas de ciência normal, sem colocá-lo (o paradigma) criticamente em questão, assim qualquer erro que venha a ocorrer na pesquisa é atribuído ao cientista e não ao paradigma. Pretendo também, mostrar que o caráter dogmático do paradigma não permite que o cientista desenvolva pesquisas visando novas descobertas que não se enquadrem nos (...) parâmetros ditados pelo mesmo, tal atitude exige total aceitação e comprometimento da comunidade científica para com o paradigma aceito, gerando assim, uma espécie de profissão de fé na capacidade do paradigma em resolver os quebra-cabeças que se apresentam na prática da ciência normal.
