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)

In much of the current academic and public discussion, conspiracy theories are portrayed as a negative phenomenon, linked to misinformation, mistrust in experts and institutions, and political propaganda. Rather surprisingly, however, philosophers working on this topic have been reluctant to incorporate a negatively evaluative aspect when either analyzing or engineering the concept conspiracy theory. In this paper, we present empirical data on the nature of the concept conspiracy theory from five studies designed to test the existence, prevalence and exact form (...) of an evaluative dimension to the ordinary concept conspiracy theory. These results reveal that, while there is a descriptive concept of conspiracy theory, the predominant use of conspiracy theory is deeply evaluative, encoding information about epistemic deficiency and often also derogatory and disparaging information. On the basis of these results, we present a new strategy for engineering conspiracy theory to promote theoretical investigations and institutional discussions of this phenomenon. We argue for engineering conspiracy theory to encode an epistemic evaluation, and to introduce a descriptive expression—such as ‘conspiratorial explanation’—to refer to the purely descriptive concept conspiracy theory.

Introduction to a Forum on Michael's Thompson "Life and Action".

According to Smell Objectivism, the smells we perceive in olfactory experience are objective and independent of perceivers, their experiences, and their perceptual systems. Variations in how things smell to different perceivers or in different contexts raise a challenge to this view. In this paper, I offer an objectivist account of non-illusory contextual variation: cases where the same thing smells different in different contexts of perception and there is no good reason to appeal to misperception. My central example is that of (...) dihydromyrcenol, a substance that can smell both woody and citrusy depending on what other odourants one has recently been exposed to. I first argue that the subjects’ apparently conflicting reports about the way dihydromyrcenol smells are best understood as comparative characterisations of a smell. Given this understanding, different reports can be correctly made in response to perceiving the very same smell. I then argue that the phenomenal difference between the experiences subjects have across contexts can be explained compatibly with Smell Objectivism. On the account proposed, subjects perceive the very same smell but different qualities, notes, or aspects of it are salient to them, depending on the context of perception. I then consider how the proposed defence of Smell Objectivism can be adapted to other cases where the same thing is reported as smelling different in different contexts. (shrink)

This paper is a contribution to the philosophical debate on visual blur from a relationalist perspective. At the same time, it offers a methodological reflection on the adequacy of explanations of phenomenal similarities and differences among perceptual experiences. The debate on seeing blurrily has been shaped by two implicit assumptions concerning our explanations of differences and similarities between experiences of seeing blurrily and other experiences. I call those assumptions into question, and argue that we do not need to provide a (...) unified explanation of the character of blurry experiences for our account to be adequate. The diversity of blurry experiences supports a different, pluralist approach to explanations of how things appear to subjects. (shrink)

What are conspiracy theories? And what, if anything, is epistemically wrong with them? I offer an account on which conspiracy theories are a unique way of holding a belief in a conspiracy. Specifically, I take conspiracy theories to be self-insulating beliefs in conspiracies. On this view, conspiracy theorists have their conspiratorial beliefs in a way that is immune to revision by counter-evidence. I argue that conspiracy theories are always irrational. Although conspiracy theories involve an expectation to encounter some seemingly disconfirming (...) evidence (allegedly planted by the conspirators), resistance to all counter- evidence cannot be justified on these grounds.

Traditionally, ‘that’-clauses occurring in attitude attributions are taken to denote the objects of the attitudes. Prior raised a famous problem: even if Frege fears that the Begriffsschrift leads to a paradox, it is unlikely that he fears a proposition, a sentence or what have you as the alleged object denoted by the ‘that’-clause. The usual way out is to say that ‘that’-clauses do not contribute the objects of the attitudes but their contents. I will show that, if we accept this (...) answer, either we’d better stop working on attitude attributions or we’d better work harder on them. (shrink)

1. Historically, our sense of smell has been deemed informationally impoverished, not very discerning, subjective, ineffable, and generally of little value (for an overview, see e.g., Barwich, 2020...

Smells are often said to be ineffable, and linguistic research shows that languages like English lack a dedicated olfactory lexicon. Starting from this evidence, I propose an account of how we talk about smells in English. Our reports about the way things smell are comparative: When we say that something smells burnt or like roses, we characterise the thing's smell by noting its similarity to the characteristic smells of certain odorous things (burnt things, roses). The account explains both the strengths (...) and limitations of our smell discourse, and has implications for philosophical discussions of the relation between language and appearances. (shrink)

Propositional attitude sentences, such as "John believes that snow is white," are traditionally taken to express the holding of a relation between a subject and what ‘that’-clauses like ‘that snow is white’ denote, i.e. propositions. On the traditional account, propositions are abstract, mind- and language-independent entities. Recently, some have raised some serious worries for the traditional account and thought that we were mistaken about the kind of entities propositions are. Over the last ten years there has then been a boom (...) of accounts of propositions in terms of mental acts. But Friederike Moltmann has recently suggested that in accounting for attitudes we should forget about mindand language-independent entities and acts and follow Twardowski in focusing instead on attitudinal objects, which are the products of our mental life. In this paper, I will focus on some semantic problems that any product-based account seems to face. Moreover, I will show that product-based accounts may be also criticised on ontological grounds. My conclusion will be that we lack a reason to think that in accounting for propositional attitudes we should focus on the alleged products of our mental lives. (shrink)

Eugenics is often referred to in debates on the ethics of reproductive technologies and practices, in relation to the creation of moral boundaries between acceptable and unacceptable technologies, and acceptable and unacceptable uses of these technologies. Historians have argued that twentieth century eugenics cannot be reduced to a uniform set of practices, and that no simple lessons can be drawn from this complex history. Some authors stress the similarities between past eugenics and present reproductive technologies and practices (what I define (...) throughout the paper as ‘the continuity view’) in order to condemn the latter. Others focus on the differences between past and present practices (what I define throughout the paper as ‘the discontinuity view’) in order to defend contemporary reproductive technologies. In this paper, I explore the meanings of the word ‘eugenics’ and the relationship between its past and present uses in terms of contemporary debates on reproductive technologies and practices. I argue that moral disagreement about present technologies originate in divergent views of condemnable and justifiable features of the past. (shrink)

According to neo-Russellianism, in a sentence such as John believes that Mont Blanc is 4000 m high, any other proper name co-referring with Mont Blanc can be substituted for it without any change in the proposition expressed. Prima facie, our practice of translation shows that this cannot be correct. We will then show that neo-Russellians have a way out of this problem, which consists in holding that actual translations are not a matter of semantics, but also make an attempt at (...) preserving some pragmatic features of the sentences to be translated. We then turn to translations that only preserve the semantic characteristics of the sentences and we argue that, although these translations are unable to show that neo-Russellianism is incorrect, they still show that it relies on some theses that seem to have no justification, apart from saving neo-Russellianism itself.

Susanne Langer is mainly known as the American philosopher who, starting from her famous Philosophy in a New Key, worked in aesthetics and famously saw art as the product of the human mind’s most important, distinctive and remarkable ability, i.e., the ability to symbolise. But Langer’s later consideration of the connection between art and symbol is propagated by an early interest in the logic of symbols themselves. This rather neglected early part of Langer’s thought and her early interests and lines (...) of reasoning, which she somehow abandoned later on to dedicate herself exclusively to the study of art, are the topic of this paper.

Relativists make room for the possibility of “faultless disagreement” by positing the existence of subjective propositions, i.e. propositions true from some points of view and not others. We discuss whether the adoption of this position with respect to a certain domain of discourse is compatible with a realist attitude towards the matters arising in that domain. At first glance, the combination of relativism and realism leads to an unattractive metaphysical picture on which reality comprises incoherent facts. We will sketch the (...) contours of a realist-relativist position called “subjectivism”, which avoids this result by giving up the assumption that the points of view of different subjects are all metaphysically “on a par”.

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.

For sentences such as (1), "Columbus knows that the sea is unpredictable", there is a face-value theory, according to which ‘that’-clauses are singular terms denoting propositions. Famously, Prior raised an objection to the theory, but defenders of the face-value theory such as Forbes, King, Künne, Pietroski and Stanley urged that the objection could be met by maintaining that in (1) ‘to know’ designates a complex relation along the lines of being in a state of knowledge having as content. Is the (...) theory safe, then? The aim of this paper is to show that a new problem for the theory arises if we consider attributions of skills, knacks, propensities and abilities. (shrink)

Propositional attitude sentences, such as (1) Pierre believes that snow is white, have proved to be formidably difficult to account for in a semantic theory. It is generally agreed that the that-clause ‘that snow is white’ purports to refer to the proposition that snow is white, but no agreement has been reached on what this proposition is. Sententialism is a semantic theory which tries to undermine the very enterprise of understanding what proposition is referred to in (1): according to sententialists, (...) in (1) reference is made to the sentence “Snow is white”. Sententialism is generally considered doomed. The two main reasons why are the famous translation argument, firstly suggested by Alonzo Church, and a problem raised by Stephen Schiffer. The purpose of this paper is to provide a unified solution to both criticisms. What I take to be the key ingredient sententialists may exploit is an observation that concerns the nature of languages and quotations: since quotation marks display the quoted material, if you are a speaker of the language the quoted material belongs to, you usually cannot but understand what is quoted. Moreover, I show that sententialists may appeal to that very observation also in order to answer another problem, pointed out by Kent Bach. I conclude that there are good reasons for resisting the temptation of introducing propositions in order to account for propositional attitude sentences. (shrink)

In English, in order to speak about Arthur’s attitudes, we use sentences like “Arthur believes that natural language is messy”. For sentences of this kind we have a standard theory, according to which the ‘that’-clause ‘that natural language is messy’ denotes a proposition. As Prior showed for the first time, the standard theory appears to be at odds with some linguistic data. Geach and Prior both assumed that linguistic data are to be taken as reliable guides to a correct semantic (...) account and I will start by raising some worries concerning their methodology. Because of these data, Prior and Geach suggested some non-standard accounts. I will then show that if we take linguistic data seriously, their non-standard accounts do not fare any better than the standard theory. My general conclusion will thus not only be that Prior’s and Geach’s methodology is disputable, but also that their conclusions do not seem to follow even if we grant the reliability of their methodology.

What are contents? The answer provided by the possible worlds approach is that contents are sets of possible worlds. This approach incurs serious problems and to solve them Jago suggests, in The Impossible, to get rid of the ‘possible’ bit and allowing some impossible worlds to be part of the game. In this note, I briefly consider the metaphysics behind Jago’s account and then focus on whether Jago is right in thinking that his worlds and his worlds only can do (...) the explanatory work he posits them for.

Merleau-Ponty’s philosophy is well known for its constant questioning of numerous theoretical preconceptions. In accordance with this perspective, this essay presents Merleau-Ponty’s observations on the oneiric experience and discusses their challenges of the mind-body dualism. Despite the critique of the Sartrian conception of dream as a result of conscience’s selffascination, the philosopher sheds light on the only valuable intuition provided by the sartrian analysis, namely a kind of passivity within the oneiric subject. However, according to Merleau-Ponty, this passivity can be (...) properly seized only by refusing the preconception of “conscience”, thus leading to the discovery of the concept of “field of existence” as the true oneiric “subject”. After having described the structure of this field through “existentials”, this paper argues that Merleau-Ponty’s retrieval of the Freudian notion of symbolism enables him to root the passivity discovered within the dreaming experience. The concept of “symbolism”, typically associated with the oneiric environment, will thus be acknowledged as the true “subject” of the dream and, more generally, of the whole existence – dream being for Merleau-Ponty a modelling of life itself. However, in his latest works, the body is equally identified as the true subject of the dream. An analysis of the oneiric corporeality in its intimate relation with symbolism will therefore disclose meaningful insights to conceive our belonging and to furtherly challenge the mind-body dualism.

The thesis that smells are objective and independent of perceivers may seem to be in tension with the phenomenon of perceptual variation. In this paper, I argue that there are principled reasons to think that perceptual variation is not a threat to objectivism about smells and is indeed integral to our perceptual relation to the objective world. I first distinguish various kinds of perceptual variation, and argue that the most challenging cases for the objectivist are those where an odourant smells (...) different in different conditions or to different perceivers but the odourant does not change, and there is neither misperception nor a simple failure to perceive a smell. I then argue that there is an independently plausible conception of olfactory experience on which even these challenging cases do not pose a threat to objectivism about smells. Following Kalderon’s work in the domain of colour perception, I argue that olfactory perception provides us with a partial perspective on the smells around us, where this perspective is constrained by the conditions of perception as well as by features of the perceiver. Within this framework, we can allow that perceivers with different sensitivities, or the same perceiver in different conditions, genuinely perceive the same objective smell even though this smell appears different to them. In turn, smells are best understood as qualitatively complex entities, different aspects of which can become perceptually available in different conditions and to different perceivers. (shrink)

This paper briefly outlines some advancements in paraconsistent logics for modelling knowledge representation and reasoning. Emphasis is given on the so-called Logics of Formal Inconsistency (LFIs), a class of paraconsistent logics that formally internalize the very concept(s) of consistency and inconsistency. A couple of specialized systems based on the LFIs will be reviewed, including belief revision and probabilistic reasoning. Potential applications of those systems in the AI area of KRR are tackled by illustrating some examples that emphasizes the importance of (...) a fine-tuned treatment of consistency in modelling reputation systems, preferences, argumentation, and evidence.

In this paper, I outline a disjunctivist proposal for understanding the intentionality of perceptions and hallucinations within a naïve realist framework. For the case of genuine perceptual experience, naïve realists can endorse a version of the view that their intentionality is phenomenally-grounded: perceptual experiences have intentionality in virtue of being relations of conscious acquaintance to aspects of the mind-independent environment. By contrast, hallucinations have intentionality dependently or derivatively, in virtue of their indiscriminability from, or similarity with respect to, perceptual experiences. (...) Within this proposal, naïve realists can allow that perceptions and hallucinations have a property in common – that of being intentionally directed at apparently mind-independent entities – whilst having wholly different metaphysical natures.

In Th e Order of Public Reason, Gerald Gaus defends an innovative and sophisticated convergence version of public reason liberalism. Th e crucial concept of his argumentative framework is that of “social morality”, intended as the set of rules apt to organize how individuals can make moral demands over each other. I claim that Gaus’s characterization of social morality and its rules is unstable because it rests on a rejection of the distinction between the normative and the descriptive. I argue (...) that such rejection is motivated by certain practical aims Gaus wishes his theory to achieve. His method and his idea that morality needs to be understood both as the dictate of impartial reasoning and as a social and historical fact come from the need for his theory to perform the task of settling the problem of order. I discuss Gaus’s philosophical attitude and, finally, distinguishing between “therapeutic” and “evaluative” approaches, I present some points of discussion for understanding the role and scope of political philosophy in general.

“Trends in Logic XVI: Consistency, Contradiction, Paraconsistency, and Reasoning - 40 years of CLE” is being organized by the Centre for Logic, Epistemology and the History of Science at the State University of Campinas (CLEUnicamp) from September 12th to 15th, 2016, with the auspices of the Brazilian Logic Society, Studia Logica and the Polish Academy of Sciences. The conference is intended to celebrate the 40th anniversary of CLE, and is centered around the areas of logic, epistemology, philosophy and history of (...) science, while bringing together scholars in the fields of philosophy, logic, mathematics, computer science and other disciplines who have contributed significantly to what Studia Logica is today and to what CLE has achieved in its four decades of existence. It intends to celebrate CLE’s strong influence in Brazil and Latin America and the tradition of investigating formal methods inspired by, and devoted to, philosophical views, as well as philosophical problems approached by means of formal methods. The title of the event commemorates one of the three main areas of CLE, what has been called the “Brazilian school of paraconsistency”, combining such a pluralist view about logic and reasoning.

Argumentation theory underwent a significant development in the Fifties and Sixties: its revival is usually connected to Perelman's criticism of formal logic and the development of informal logic. Interestingly enough it was during this period that Artificial Intelligence was developed, which defended the following thesis (from now on referred to as the AI-thesis): human reasoning can be emulated by machines. The paper suggests a reconstruction of the opposition between formal and informal logic as a move against a premise of an (...) argument for the AI-thesis, and suggests making a distinction between a broad and a narrow notion of algorithm that might be used to reformulate the question as a foundational problem for argumentation theory.

In Book 3 of Herodotus’Histories, seven Persian noblemen discuss which form of government would best fit the empire. If we accept its dramatic date, 522 BCE, this scene offers the first example of a comparative definition of monarchy, oligarchy and democracy. It offers, even more strikingly, the very first description of the government of the many — a novel political order that will eventually be called a democracy. The power of the people, this quintessentially Hellenic thing, was then a Persian (...) invention, an idea that occurred originally not to the masses of a polis, not to an Athenian demagogue, but to a relative of the Great King. In the course of the narrative, democracy will prove to be a unique form of government: the winning one. The Histories take up the challenge of recounting, and accounting for, a most improbable defeat, and for an even less foreseeable victory. The text does so not by preaching a morality of self-knowledge and self-control, but by exposing the realistic effects of different kinds of rule. Against the odds, democracy enhances and strengthens a small polis, Athens, making it grand and successful. Notwithstanding its immeasurable capabilities, the Persian monarchy fails. The turning point is the battle of Salamis, a prowess of the dêmos. A theatrical pause, in the narration of how the Great Kings came to prepare their campaigns against Greece, the debate offers a counterfactual explanation to historical events, in terms of political theory. This is, I will argue, the effect of the scene on the Histories. (shrink)

In 1893, three young men in their early twenties, Xavier Léon, Élie Halévy and Léon Brunschvicg, founded the Revue de métaphysique et de morale. This article explores the motives of this endeavour, and how they made the journal the centre of three great scientific enterprises: in 1894 they promoted the edition of Descartes’s Œuvres completes; in 1900, they organized the first international congress of philosophy in Paris; in 1901, they founded the Societé française de philosophie.

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.

Beyond medicalization: what’s left of pain With the help of the ethnopsychiatric research led by Tobie Nathan and other fundamental anthropological insights, we want to analyze how the medical and psychological gaze shapes our understanding and narration of pain and death.

In his book, "Prejudice", Endre Begby offers a novel and engaging account of the epistemology of prejudice which challenges some of the standard assumptions that have so far guided the recent discussion on the topic. One of Begby's central arguments against the standard view of prejudice, according to which a prejudiced person necessarily displays an epistemically culpable resistance to counterevidence, is that, qua stereotype judgments, prejudices can be flexible and rationally maintained upon encountering many disconfirming instances. By expanding on Begby's (...) analysis, I argue that, given the variety of truth conditions for true generic statements, the generic form of stereotype judgements can sometimes make prejudice extremely resistant to encounters with statistical facts about the distribution of the property among members of a certain group. At the same time, I argue that a more careful consideration of the generic form of stereotypes also allows us to recognize that evidence about how many members of the kind instantiate a property is not the only type of evidence which could disconfirm a prejudice. Evidence of no explanatory relation between a kind and a property should also have a direct effect on a prejudicial belief. For this reason, things may not look as dim for the standard view of prejudice in assessing paradigmatic instances of prejudicial beliefs as irrationally resistant to evidence. (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.

According to the extended cognition thesis, an agent’s cognitive system can sometimes include extracerebral components amongst its physical constituents. Here, we show that such a view of cognition has an unjustifiably anthropocentric focus, for it tends to depict cognitive extensions as a human-only affair. In contrast, we will argue that if human cognition extends, then the cognition of many non-human animals extends too, for many non-human animals rely on the same cognition-extending strategies humans rely on. To substantiate this claim, we (...) will proceed as follows. First (Sect. 1), we will introduce the extended cognition thesis, exposing its anthropocentric bias. Then, we will show that humans and many non-human animals rely on the same cognition-extending strategies. To do so, we will discuss a variety of case studies, including “intrabodily” cognitive extensions such as the spinal cord (Sect. 2), the widespread reliance on epistemic actions to solve cognitive tasks (Sect. 3) and cases of animal cognitive offloading (Sect. 4). We’ll then allay some worries our claim might raise (Sect. 5) to then conclude the paper (Sect. 6). (shrink)

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.

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)

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 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.

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)

Funds and positions in philosophy should be awarded through systems that are reliable, objective, and efficient. One question usually taken to be relevant is how many publications people have in a group of well-respected journals. In the context of significant competition for jobs and funding, however, relying on quantity of publications creates a serious downside: the oft-lamented demand that we publish or perish. This article offers a systematic review of the problems involved in contemporary academic philosophy, and argues that the (...) resulting situation is bad not just for individual philosophers but also for philosophy itself: we are not working as a discipline to as high a standard as we might. The article then suggests some potential solutions, including some more detailed considerations around what seems a particularly promising option: a professional code of conduct for philosophers.

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)

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)

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.

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.

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)
