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)

Paraconsistency is the study of logical systems with a non-explosive negation such that a pair of contradictory formulas (with respect to such negation) does not necessarily imply triviality, discordant to what would be expected by contemporary logical orthodoxy. From a purely logical point of view, the significance of paraconsistency relies on the meticulous distinction between the general notions of contradictoriness and triviality of a theory—respectively, the fact that a given theory proves a proposition and its negation, and the fact that (...) a given theory proves any proposition (in the language of its underlying logic). Aside from this simple rationale, the formal techniques and approaches that meet the latter definitional requirement are manifold. Furthermore, it is not solely the logical-mathematical properties of such systems that are open to debate. Rather, there are several foundational and philosophical questions worth studying, including the very question about the nature of the contradictions allowed by paraconsistentists. This entry aims to advance a brief account of some distinct approaches to paraconsistency, providing a panorama on the development of paraconsistent logic. (shrink)

Na era das tecnologias digitais, entender vieses algorítmicos por meio das teorias da verdade ajuda a fazer perguntas cujas respostas facilitam a filtragem da informação de forma mais eficaz. O ganho é a compreensão aprofundada da realidade.

When interacting with other people, we assume that they have their reasons for what they do and believe, and experience recognizable feelings and emotions. When people act from weakness of will or are otherwise irrational, what they do can still be comprehensible to us, since we know what it is like to fall for temptation and act against one’s better judgment. Still, when someone’s experiences, feelings and way of thinking is vastly different from our own, understanding them becomes increasingly difficult. (...) Delusions and psychosis are often seen as marking the end of intelligibility. In this paper, I argue first for the importance of seeing other people as intelligible as long as this is at all possible. Second, I argue, based on both previous literature and my own lived experience, that more psychotic phenomena than previously thought can be rendered at least somewhat intelligible. Besides bizarre experiences like illusions, hallucinations and intense feelings of significance, I also explain what it is like to lose one’s bedrock, and how this loss impacts which beliefs one has reason to reject. Finally, I give an inside account of some disturbances of reason, and show that there are important similarities between certain psychotic reasoning problems and common non-pathological phenomena.

In this book symposium text, I focus on Ciurria’s critique of P. F. Strawson’s incredibly influential paper “Freedom and Resentment”, and more generally present-day Strawsonians about moral responsibility. Ciurria rightfully argues that the picture painted of “our responsibility practices” is highly idealized; it ignores crucial power asymmetries and oppression. I agree with this. However, it seems to me that Ciurria sometimes lacks awareness of exactly how profound the disagreement between her and Strawson and his followers is.

"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.

How should we adjust our beliefs in light of the testimony of those who are in a better epistemic position than ourselves, such as experts and other epistemic superiors? In this paper, I develop and defend a deference model of epistemic authority. The paper attempts to resolve the debate between the preemption view and the total evidence view of epistemic authority by taking an accuracy-first approach to the issue of how we should respond to authoritative and expert testimony. I argue (...) that when we look at the debate through the lens of accuracy, it becomes clear that matters are more complicated than either the preemption view or the total evidence view are able to account for. Consequently, a deference model, outlined within a credence-based framework, does a better job of capturing the relevant phenomena, and explaining how we should update our beliefs in response to epistemically authoritative testimony.

Wouter Kusters argues that madness has much to offer philosophy, as does philosophy to madness. In this paper, i support both claims by drawing on a mad phenomenon which I label Radical Psychotic Doubt, or RPD. First, although skepticism is a minority position in epistemology, it has been claimed that anti-skeptical arguments remain unsatisfying. I argue that this complaint can be clarified and strengthened by showing that anti-skeptical arguments are irrelevant to RPD sufferers. Second, there's a debate about whether so-called (...) hinge commitments are beliefs or not. I argue that RPD can be used to strengthen the case that they are. Moreover, if hinges are beliefs, some madpeople are more epistemically rational than some sane philosophers. Third, drawing on my own mad experiences, I challenge evidentialism by presenting a better candidate for a truly forced cchoice about what to believe than William James' traditional religious example. I further show that in certain psychiatric contexts, evidentialism has more radical implications than Jamesian pragmatism, which comes out as more conservative. Finally, I discuss how philosophical theories like pragmatism and Pyrrhonism can provide inspiration for new and much-needed coping strategies for RPD sufferers. (shrink)

The medical and social model of disability is discussed and debated among researchers, scholars, activists, and people in general. It is common to hold a mixed view and believe that some disabled people suffer more from social obstacles and others more from medical problems inherent in their bodies or minds. Rachel Cooper discusses possible ‘test environments’, making explicit an idea which likely plays an implicit part in many disability discussions. We place or imagine placing the disabled person in a range (...) of different environments. If there is a relevant test environment in which they do fine, their problem was societal/external; if there is not, it was medical/internal. Cooper admits that deciding on the appropriate range of test environments is an ethical and political question. In this chapter, I argue that we often ought to widen our scope when discussing psychiatric disabilities. (shrink)

Psychiatric patients sometimes ask where to draw the line between who they are – their selves – and their mental illness. This problem is referred to as the self-illness ambiguity in the literature; it has been argued that solving said ambiguity is a crucial part of psychiatric treatment. I distinguish a Realist Solution from a Constructivist one. The former requires finding a supposedly pre-existing border, in the psychiatric patient’s mental life, between that which belongs to the self and that which (...) belongs to the mental illness. I argue that no such border exists, and that attempts to find it might even render the felt ambiguity worse. Instead, any solution must be constructivist; the patient (and others) should deliberate and discuss what to identify with or not. I further argue that psychiatric patients need not see their mental illness as wholly distinct from themselves to avoid ‘identifying with their diagnoses' in a problematic way. Finally, we can excuse problematic behaviour by mentally ill people – in fact, we can do so in a more nuanced and constructive way – while rejecting the view that the mental illness is wholly distinct from the patient’s self.

En este trabajo me ocuparé de las resonancias que tuvo el modo en el que Hume aborda la cuestión de la materialidad de la mente en uno de los materialistas más notables de las Islas Británicas del siglo XVIII, Joseph Priestley. La influencia que ejerció el enfoque humeano acerca del materialismo en la obra de Priestley no ha sido suficientemente puesta de relieve o ha sido desestimada. En buena medida, esto se debe a que Priestley tienen una actitud crítica hacia (...) las consecuencias escépticas y ateas que se desprenden de la filosofía de Hume, por lo que generalmente se tiende a presentarlo como uno de sus adversarios. Sin embargo, existen dos grandes puntos de contacto entre sus propuestas que estudiaré en lo que sigue: (1) ambos abordan la cuestión del origen del pensamiento, haciendo a un lado la cuestión de la naturaleza de la sustancia de la que estaría compuesta la mente —por ser inaccesible a nuestro conocimiento— y preguntándose por la causa del pensamiento, y (2) Priestley se sirve de una concepción de la causalidad inspirada en buena medida por la de Hume y la emplea como uno de los pilares de su materialismo, al sostener que la conjunción constante entre características mentales y organismos con un cerebro funcional nos da la mayor seguridad posible de que existe una relación causal entre ambos.

It has been argued that we cannot be morally responsible in the sense required to deserve blame or punishment if the world is deterministic, but still morally responsible in the sense of being apt targets for moral criticism. Desert-entailing moral responsibility is supposed to be more freedom-demanding than other kinds of responsibility, since it justifies subjecting people to blame and punishments, is nonconsequentialist, and has been shown by thought experiments to be incompatible with determinism. In this paper, I will show (...) that all these arguments can be resisted. (shrink)

In _"I that is We, We that is I"_ leading scholars analyze the many facets of Hegel’s formula for the intersubjective structure of human life and explores its relevance for debates on social ontology, recognition, action theory, constructivism, and naturalism.

In this article I intend to show the strict relation between the notions of “second nature” and “recognition”. To do so I begin with a problem (circularity) proper to the theory of Hegelian and post- Hegelian Anerkennung. The solution strategy I propose is signifi cant also in terms of bringing into focus the problems connected with a notion of “space of reasons” that stems from the Hegelian concept of “Spirit”. I thus broach the notion of “second nature” as a bridgeconcept (...) that can play a key role both for a renewal of the theory of Anerkennung and for a rethinking of the “space of reasons” within the debate between Robert Brandom and John McDowell. Against this background I illustrate the novelties introduced by the dialectical conception of the relation between fi rst and second nature developed by Hegel and the contribution this idea can make to a revisited theory of recognition as a phenomenon articulated on two levels. I then return to the question of the space of reasons to show the contribution the renewed conception of recognition as second nature makes to the definition of its intrinsic sociality as something that is not in principle opposed to a sense of naturalness.

Justin Garson introduces the distinction between two views on Madness we encounter again and again throughout history: Madness as dysfunction, and Madness as strategy. On the latter view, Madness serves some purpose for the person experiencing it, even if it’s simultaneously harmful. The strategy view makes intelligible why Madness often holds a certain allure – even when it’s prima facie terrifying. Moreover, if Madness is a strategy in Garson’s metaphorical sense – if it serves a purpose – it makes sense (...) to use consciously chosen strategies for living with Madness that doesn’t necessarily aim to annihilate or repress it as far as possible. In this paper, we use our own respective stories as case studies. We have both struggled to resist the allure of Madness, and both ended up embracing a kind of Pyrrhonian scepticism about reality instead of clinging to sane reality. (shrink)

I tackle the definition of the relation between first and second nature while examining some problems with McDowell's conception. This, in the first place, will bring out the need to extend the notion of second nature to the social dimension, understanding it not just as `inner' second nature — individual mind — but also as `outer' second nature — objective spirit. In the second place the dialectical connection between these two notions of second nature will point the way to a (...) critical use of the concept itself, which will link up with a theory of reification. Furthermore, I shall endeavor to fit my reflection into the problematic constellation of critical theory: my analysis in fact rests on the question whether, within a critical theory, the philosophy of nature can be recaptured today, in such a way as to give meaning to the very notion of socio-philosophical criticism of reality.

The paper proposes a reconstruction of some fragments of Hegel’s Jena manuscripts concerning the natural genesis of recognitive spiritual consciousness. On this basis it will be argued that recognition has a foothold in nature. As a consequence, recognition should not be understood as a bootstrapping process, that is, as a self-positing and self-justifying normative social phenomenon, intelligible within itself and independently of anything external to it.

n this paper, I analyse Rahel Jaeggi’s socio-ontological account of forms of life. I show that her framework is a two-sided one, since it involves an understanding of forms of life both as inert bundles of practices and as having a normative structure. Here I argue that this approach is based on an a priori argument which assumes normativity as the condition of intelligibility of social criticism. I show that the intimate tension between these two sides is reflected in the (...) socio-ontological model of the constitution of social phenomena, which on the one side is understood in terms of habituation and materialization, and on the other side in terms of constitution through norms. The second side in the end prevails and leads to some sort of normative essentialism which involves a prescriptive meta-theoretical understanding of normativity combined with a socio-ontological model of constitutive rules. I then analyse two arguments that Jaeggi offers in support of her assumption that normative constitution is the deep structure of social practices. I name these the functional- teleological argument, and the crisis developmental argument, and argue that neither succeeds in proving that practices are not normatively underdetermined. (shrink)

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)

Esta es la entrada que preparé sobre Catharine Trotter Cockburn para la Enciclopédia Mulheres na Filosofía, de la Universidade Estadual de Campinas (Brasil).

Durante los siglos XVII y XVIII hubo un intenso debate en las Islas Británicas en torno al materialismo. Mi objetivo consiste en caracterizar la postura de David Hume en el marco de ese debate. Sostengo que, no obstante rechazar la metafísica sustancialista para centrarse en el estudio de las percepciones, Hume sienta una posición respecto de la relación entre mente y materia. Sin embargo, esa posición reviste cierta complejidad en tanto no es explicitada en los textos que se editaron en (...) vida de Hume. Propongo definirla como un materialismo restringido, ya que, respecto de la naturaleza de la mente, Hume desestima tanto las posturas materialista como inmaterialista, pero respecto de las causas del pensamiento, termina acercándose al materialismo a partir de argumentos basados en la experiencia y en la analogía con la naturaleza.

In this paper I will argue that critical theory needs to make its socio-ontological commitments explicit, whilst on the other hand I will posit that contemporary social ontology needs to amend its formalistic approach by embodying a critical theory perspective. In the first part of my paper I will discuss how the question was posed in Horkheimer’s essays of the 1930s, which leave open two options: (1) a constructive inclusion of social ontology within social philosophy, or else (2) a program (...) of social philosophy that excludes social ontology. Option (2) corresponds to Adorno’s position, which I argue is forced to recur to a hidden social ontology. Following option (1), I first develop a metacritical analysis of Searle, arguing that his social ontology presupposes a notion of 'recognition' which it cannot account for. Furthermore, by means of a critical reading of Honneth, I argue that critical theory could incorporate a socioontological approach, giving value to the constitutive socio-ontological role of recognition and to the socio-ontological role of objectification. I will finish with a proposal for a socio-ontological characterization of reification which involves that the basic occurrence of recognition is to be grasped at the level of background practices.

Catharine Trotter Cockburn’s metaphysics dissolves the necessary relationship between immateriality, immortality and thought. While in her youth this leads her to admit the possibility of thinking matter, in her mature work, it allows her to conceive space as non-thinking immaterial substance that links non-thinking material substance and thinking immaterial substance. To ground this conception of space, she draws on the thesis of the great chain of being. However, the possibility of thinking matter is not consistent with the hierarchy of beings, (...) because within this frame matter occupies the lowest place. My aim is to evaluate whether there is any alternative within Trotter's philosophy to solve this contradiction. -/- La metafísica de Catharine Trotter Cockburn disuelve la relación necesaria entre inmaterialidad, inmortalidad y pensamiento. Mientras que en su juventud esto la lleva a admitir la posibilidad de la materia pensante, en su madurez le permite concebir al espacio como sustancia inmaterial no pensante que oficia como eslabón entre la sustancia material no pensante y la sustancia inmaterial pensante. Para ello, apela también a la tesis de la gran cadena del ser. Sin embargo, la posibilidad de la materia pensante no es consistente con la tesis de la jerarquía de seres, porque en ella la materia ocupa el lugar más bajo. Me propongo estudiar si existe alguna alternativa dentro de la filosofía de Trotter que permita resolver esta contradicción. (shrink)

En la segunda mitad del siglo XVIII tuvo lugar un debate entre Thomas Reid y Joseph Priestley acerca de la naturaleza de la mente y su interacción con el cuerpo. En el marco de la defensa de la religión cristiana y en nombre de principios metodológicos experimentalistas y newtonianos, los autores defienden propuestas radicalmente diferentes acerca de la relación entre la mente y la materia. Sus divergencias se vinculan con la interpretación del método newtoniano y su concepción de la materia, (...) lo que delineará dos actitudes: una dualista, de carácter más conservador por parte de Reid y una materialista, heterodoxa e innovadora por parte de Priestley.

Martha Nussbaum argues that animals are entitled to a flourishing life according to the norm for their species. Nussbaum furthermore suggests that in the case of dogs, breed norms as well as species norms are relevant. Her theses capture both common intuitions among laypeople according to which there is something wrong with the breeding of “unnatural” animals, or animals that are too different from their wild ancestors, and the dog enthusiast’s belief that dogs departing from the norms for their breed (...) are tragic. I argue that the high diversity of the dog species and the ultimate arbitrariness of breed norms support the thesis that a conception of welfare must be tied to what the individual requires in order to flourish. In the second part of the paper, I discuss the implications that an individualized welfare conception has for the breeding of dogs for conformation shows, for the pet market and for the performance of various tasks for which we need working dogs.

ABSTRACT A restricted interpretation of Humean methodology understands his experimentalism solely in terms of reducing epistemic statements to private sensory impressions accessible via introspection. My aim is to revise this interpretation by means of criticizing the connection it establishes between the maxim of not going beyond experience and the copy principle. I will show that this interpretation is inconsistent with the way Hume conceives the experimental method, since there is textual evidence to affirm that experience should not be understood in (...) terms of sensory impressions only, and that the science of human nature is not restricted to the study of the mental contents only, but it is nourished in the same way by the observation of social interaction. Finally, I will argue that the method Hume proposes does not prevent intersubjective verification of the empirical evidence, since the principle of sympathy enables the communication of mental states, which makes them devoid of their private character.

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)

Breeders of purebred dogs usually have several goals they want to accomplish, of which canine wellbeing is one. The purpose of this article is to investigate what we ought to do given this goal. Breeders typically think that they fulfil their wellbeing-related duties by doing the best they can within their breed of choice. However, it is true of most breeders that they could produce physically and mentally healthier dogs if they switched to a healthier breed. There are a few (...) breeds that are healthier than other breeds as well as mutts; we could maximize wellbeing for the next generations by focusing all our breeding resources on those. However, in the long run such a strategy would severely deplete the canine gene pool. If we are to breed for wellbeing in the long run, we must thus weigh the benefits of selection against physical and mental problems against the benefits of genetic diversity. The optimal breeding strategy for canine wellbeing is to preserve many breeds, though not all of them. Furthermore, we ought to combine strict health programs with looser barriers between breeds. Such a policy conflicts with the goal of breed preservation, at least if we think of breeds as populations registered within kennel clubs rather than types of dogs, but not with the goal of producing good working dogs capable of performing various tasks.

My response to Rashed's critique of my account as theorizing instead of showing what it is like.

Introductory essay to the collection "I that is We, We that is I" (ed. by Italo Testa and Luigi Ruggiu, Brill Books, 2016). In this book an international group of philosophers explore the many facets of Hegel’s formula which expresses the recognitive and social structures of human life. The book offers a guiding thread for the reconstruction of crucial motifs of contemporary thought such as the socio-ontological paradigm; the action-theoretical model in moral and social philosophy; the question of naturalism; (...) and the reassessment of the relevance of work and power for our understanding of human life. This collection addresses the shortcomings of Kantian and constructivist normative approaches to social practices and practical rationality it involves. It sheds new light on Hegel’s take on metaphysics and puts into question some presuppositions of the post-metaphysical interpretative paradigm. (shrink)

Dewey’s notion of second nature is strictly connected with that of habit. I reconstruct the Hegelian heritage of this model and argue that habit qua second nature is understood by Dewey as a something which encompasses both the subjective and the objective dimension – individual dispositions and features of the objective natural and social environment.. Secondly, the notion of habit qua second nature is used by Dewey both in a descriptive and in a critical sense and is as such a (...) dialectical concept which connects ‘impulse’ and ‘habit’, ‘original’ or ‘native’ and ‘acquired’ nature, ‘first’ and ‘second nature’. Thirdly, the ethical model of second nature as habituation and the aesthetic model of second nature as art are for Dewey not opposed to one another, since by distinguishing ‘routine’ and ‘art’ as two modes of habit, he makes space for an expressive and creative notion of second nature. Finally, I argue that the expressive dialectics of habit formation plays a crucial role in Dewey’s critical social philosophy and that first and second nature operate as benchmark concepts for his diagnosis of social pathologies.

En este trabajo nos proponemos hacer un aporte para esclarecer el sentido y la función de la experiencia en el marco de la teoría del conocimiento de Hume. Para ello examinaremos dos interpretaciones que pueden reconstruirse en la literatura secundaria: la que la entiende como impresiones simples de sensación y la que la concibe como patrones de percepciones conectadas. Consideramos que la primera perspectiva no es adecuada para comprender el rol epistémico de la experiencia, lo que nos inclina hacia la (...) segunda interpretación. Sin embargo, esta última no ha sido lo suficientemente desarrollada por los autores que la sugieren. Nuestro propósito es llevar a cabo esa tarea pendiente, ofreciendo una serie de precisiones que la hacen más robusta a los fines de elucidar por qué para Hume la experiencia es la piedra de toque en el conocimiento sobre cuestiones de hecho. Así, mostraremos que el sentido que adquiere la experiencia en las inferencias causales es el de casos que recogemos mediante la observación y organizamos en colecciones o patrones, los que funcionan como evidencia para establecer o justificar enunciados epistémicos. Por último, para comprender la especificidad de su función en este tipo de inferencias, distinguiremos la experiencia de las impresiones y del hábito. (shrink)

By Belief Revision it is understood a system that logically explains the rational process of changing beliefs by taking into account a new piece of information. The most influential approach in this field of study, the AGM system, proposed by Alchourrón, Gärdenfors, and Makinson, postulates rationality criteria for different types of belief change. In this paper I shall assess the relationship between those criteria and argue for an opposition between the principles of Information Economy and Consistency. Furthermore, I shall argue (...) that Paraconsistent Belief Revision manages to minimise this friction in the best possible way. (shrink)

Qual o lugar da filosofia nos dias atuais? Diante das inúmeras respostas possíveis a esta questão, nos debruçaremos em alguns tópicos que podemos inserir na chamada Ética Informacional, um ramo de investigação filosófico-interdisciplinar relativamente recente que discute problemas oriundos da relação ser humano/tecnologias digitais. Temas como privacidade informacional, arrogância epistêmica e divisão digital serão discutidos e relacionados, com o intuito de ilustrar o papel da filosofia na compreensão da complexidade inerente às dinâmicas sociais no contexto da sociedade da informação. Argumentaremos (...) que pensar o mundo contemporâneo a partir do viés da ética informacional se faz cada dia mais imprescindível para que possamos entrar em sintonia com as rápidas mudanças que a revolução informacional impõe à vida em sociedade e não sermos levados pelas enxurradas informacionais que presenciamos diariamente.

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)

Saul Smilansky’s theory of free will and moral responsibility consists of two parts; dualism and illusionism. Dualism is the thesis that both compatibilism and hard determinism are partly true, and has puzzled many philosophers. I argue that Smilansky’s dualism can be given an unquestionably coherent and comprehensible interpretation if we reformulate it in terms of pro tanto reasons. Dualism so understood is the thesis that respect for persons gives us pro tanto reasons to blame wrongdoers, and also pro tanto reasons (...) not to blame them. These reasons must be we ighed against each other (and against relevant consequentialist reasons) in order to find out what we all things considered ought to do. (shrink)

The belief that obese people ought to lose weight and keep it off is widespread, and has a profound negative impact on the lives of the obese. I argue in this paper that most obese people have no such obligation, even if obesity is bad, and caused by calorie input exceeding output. Obese people do not have an obligation to achieve long-term weight loss if this is impossible for them, is worse than the alternative, or requires such an enormous effort (...) in relation to what stands to be gained that this option is supererogatory rather than obligatory. It is highly plausible that most obese people fall into one of these three groups. Politicians may still have obligations to fight obesity, but they ought to do so through progressive politics rather than blaming and shaming. (shrink)

In this paper recognition is taken to be a question of social ontology, regarding the very constitution of the social space of interaction. I concentrate on the question of whether certain aspects of the theory of recognition can be translated into the terms of a socio-ontological paradigm: to do so, I make reference to some conceptual tools derived from John Searle's social ontology and Robert Brandom's normative pragmatics. My strategy consists in showing that recognitive phenomena cannot be isolated at the (...) level of human interaction, and are, rather, in part proper to animal interaction as well. Furthermore, it is argued that recognitive powers are constitutive powers more basic than deontic ones and play a role much broader than the one they in fact assume in Searle and in Brandom.

Published on Daily Philosophy 2021-10-18 Why do we have a criminal justice system? What could possibly justify the state punishing its citizens? Philosophers, scholars of law, politicians and others have proposed different justifications, one of them being retributivism: the view that we ought to give offenders the suffering that they deserve for harming others. However, intentionally harming other people and making them suffer is serious business. If we are to do this in the name of what’s right and good, we (...) better be very certain that what we do really is right and good. The so-called Epistemic Argument Against Retributivism calls this certainty into question. (shrink)
