Neste capítulo, analisa-se a documentação visual dos protestos de 2013, contrastando a cobertura da grande mídia em São Paulo e Rio de Janeiro com a de ativistas usando as tecnologias de nova mídia. Os temas centrais são a forma como o exercício do poder político é mediado através de novas tecnologias de mídia e a racionalidade política que anima os ativistas. Dito de outro modo, pergunta-se: por que os atores criaram imagens da forma que o fizeram e que objetivos (...) políticos estavam em jogo? No que se segue, consideram-se principalmente as utilizações de filmagens feitas à mão com telefone celular, a difusão de tais imagens pelas redes sociais (mídia social) e a interação entre os ativistas e os governos municipais. Sugere-se que as novas tecnologias de mídia, através da qual a linguagem visual dos ativistas foi criada, eram postas a serviço de um tipo de política radical, no sentido de almejar algo diferente na raiz. Em vez de um modo de ação política com objetivos governamentais definitivos, os ativistas re-mediaram novas tecnologias de mídia como um tipo de equipamento que poderia gerar novas relações e subjetividades e, assim, acesso a um futuro intencionalmente indeterminado.

O presente texto tem por pressuposto teórico a determinação das práticas e teorias pedagógicas, bem como das controvérsias epistemológicas, pela estrutura e superestrutura indissociáveis vigentes. O cenário é o da globalização econômica e cultural. Nesse cenário, destaca-se a pedagogia da hegemonia visando decifrar suas implicações na construção de um novo homem e de um novo consenso ideológico, político e social. Conclui-se que a pedagogia da hegemonia, desde o Estado educador, passando pelas igrejas, mídias e ONG's, tenta sedimentar a "ordem" (...) mundial capitalista-burguesa como algo inevitável.This paper has the theoretical assumptions in determining the practical and pedagogical theories, the controversies in the current epistemological and inseparable relationship between structure and superstructure. The scenario is the economic and cultural globalization. In this scenario, we highlight the teaching of hegemony that seeks to decipher their implications in the construction of a new man and a new ideological consensus, political and social. We conclude that the pedagogy of hegemony from the Educator State, through churches, media and ONGs are trying to consolidate the "order" of the bourgeois-capitalist world as inevitable. (shrink)

Vivemos, hoje, sob a hegemonia do paradigma tecnocêntrico, mercadológico e midiático. A Tecnociência, o Mercado e a Mídia se constituem em autênticos horizontes no interior dos quais se desvelam todos os âmbitos da experiência humana. Isso posto, o que o ser humano e a religião se tornam nessa nova situação epocal? A Tecnociência tornou-se horizonte de compreensão do ser humano em relação ao mundo e si próprio. Não apenas nossos estilos de vida, nosso modo de trabalhar e viver, são condicionados (...) pela técnica, mas também nossa identidade mais profunda é dada pela diferença técnica. Somos ainda vítimas da “absolutização do Mercado”: uma autêntica mercantilização da vida e, portanto, também da cultura e da religião. O mercado vai se impondo como único cenário de nossa trama civilizacional atual. Nossos fluxos vitais e também os valores e símbolos culturais e religiosos se tornam mercadoria de consumo e de descarte. Em tal contexto, a religião corre o risco de ser acometida por um duplo reducionismo. Esse tem sido o preço que a religião decidiu pagar em troca do direito de cidadania em um mundo dominado pela Tecnociência, pelo Mercado e pela Mídia. Palavras-Chave : Tecnociência. Mercado. Mídia. Religião. Mercantilização da vida. Absolutização do Mercado.We live, today, under the hegemony of a techno-centric, market-based and mediatic paradigm. Techno-science, the Market and the Mass Media are authentic horizons, in the interior of which are uncovered all of the scopes of the human experience. Having said that, what does human kind and religion become in this new era? Techno-science has become a horizon of comprehension of man regarding the world and of himself. Not only our lifestyles and our way of life and work are conditioned by technology, but also our deeper identity is lost by the technical difference. We are still victims of the “absolutization of the market”: an authentic mercantilization of life and, therefore, culture and religion. The market presents itself as the only setting of our present civilization’s story line. Our vital fluctuations, as well as the values and religious and cultural symbols become merchandise to consume and discard. In such a context, religion runs the risk of being attacked by a double reductionism. This has been the price that religion decided to pay in exchange for the right of citizenship in a world dominated by techno-science, by the market and by the Mass Media. Keywords : Techno-science. Market. Mass Media. Religion. Mercantilization of life. Absolutization of the market. (shrink)

Este artigo apresenta os principais temas de discussão que emergiram em um grupo de leitores de uma rede social. Discute o conceito de pedagogias da visibilidade, que no contexto atual, constituem materialidades simbólicas de uma nova maneira de se fazer existir frente a emergência das redes sociais. Foi utilizada a análise de conteúdo como técnica de pesquisa. Os resultados apontam que a discrição comedida e a introspecção como marca da personalidade leitora em tempos outros, o leitor das redes sociais clama (...) visibilidade e dela depende a sua sobrevivência nos espaços virtuais e estes, por sua vez, incitam-no a assumir um comportamento de auto celebrização, que é valorizado pela rede social enquanto comunidade de leitores. Apresenta uma matriz de tipificação das postagens que buscou agregar informações acerca das pedagogias da visibilidade das quais os leitores fizeram uso para serem vistos. As considerações finais apontam que nas redes sociais, ao se comportar como uma celebridade, o leitor sai dos silenciosos espaços introspectivos e solitários nos quais realizava suas leituras e tinha garantida a inviolabilidade dos seus gestos de leitor.

The sixteenth-century Cossacks became the favourite topic of Ukrainian authors of the nineteenth century who dealt with national and individual identity issues. Nikolai Gogol, the celebrated Russian author who had Ukrainian origin and was born in a Cossack village, wrote the epic romance of Taras Bulba, which narrated the story of Cossacks and their struggle for preserving their independence. While the work has been previously studied under the light of postcolonial theoretical framework, using the concepts developed by Homi Bhabha to (...) scrutinize the situation and the destiny of the two main hybrid characters, Taras Bulba’s sons, takes a step further and reveals the deeply ingrained anxiety and ambivalence in the Cossack mentality. The article focuses on the two main hybrid characters who choose divergent paths upon encountering the conflict brought to them by the imperial power. (shrink)

This comprehensive account of the concept and practices of deduction is the first to bring together perspectives from philosophy, history, psychology and cognitive science, and mathematical practice. Catarina Dutilh Novaes draws on all of these perspectives to argue for an overarching conceptualization of deduction as a dialogical practice: deduction has dialogical roots, and these dialogical roots are still largely present both in theories and in practices of deduction. Dutilh Novaes' account also highlights the deeply human and in fact social nature (...) of deduction, as embedded in actual human practices; as such, it presents a highly innovative account of deduction. The book will be of interest to a wide range of readers, from advanced students to senior scholars, and from philosophers to mathematicians and cognitive scientists. (shrink)

Two periods in the history of logic and philosophy are characterized notably by vivid interest in self-referential paradoxical sentences in general, and Liar sentences in particular: the later medieval period (roughly from the 12th to the 15th century) and the last 100 years. In this paper, I undertake a comparative taxonomy of these two traditions. I outline and discuss eight main approaches to Liar sentences in the medieval tradition, and compare them to the most influential modern approaches to such sentences. (...) I also emphasize the aspects of each tradition that find no counterpart in the other one. It is expected that such a comparison may point in new directions for future research on the paradoxes; indeed, the present analysis allows me to draw a few conclusions about the general nature of Liar sentences, and to identify aspects that would require further investigation.

A distinction often drawn is one between conservative versus revisionary conceptions of philosophical analysis with respect to commonsensical beliefs and intuitions. This paper offers a comparative investigation of two revisionary methods: Carnapian explication and ameliorative analysis as developed by S. Haslanger. It is argued that they have a number of common features, and in particular that they share a crucial political dimension: they both have the potential to serve as instrument for social reform. Indeed, they may produce improved versions of (...) key concepts of everyday life, for example those pertaining to social categories such as gender and race, which in turn may lead to social change. The systematic comparison of these two frameworks offered here, where similarities as well as differences are discussed, is likely to provide useful guidance to practitioners of both approaches, as it will highlight important aspects of each of them that tend to remain implicit and under-theorized in existing applications of these methodologies to specific questions.

Formal languages are widely regarded as being above all mathematical objects and as producing a greater level of precision and technical complexity in logical investigations because of this. Yet defining formal languages exclusively in this way offers only a partial and limited explanation of the impact which their use actually has. In this book, Catarina Dutilh Novaes adopts a much wider conception of formal languages so as to investigate more broadly what exactly is going on when theorists put these tools (...) to use. She looks at the history and philosophy of formal languages and focuses on the cognitive impact of formal languages on human reasoning, drawing on their historical development, psychology, cognitive science and philosophy. Her wide-ranging study will be valuable for both students and researchers in philosophy, logic, psychology and cognitive and computer science. (shrink)

Permutation invariance is often presented as the correct criterion for logicality. The basic idea is that one can demarcate the realm of logic by isolating specific entities—logical notions or constants—and that permutation invariance would provide a philosophically motivated and technically sophisticated criterion for what counts as a logical notion. The thesis of permutation invariance as a criterion for logicality has received considerable attention in the literature in recent decades, and much of the debate is developed against the background of ideas (...) put forth by Tarski in a 1966 lecture (Tarski 1966/1986). But as noted by Tarski himself in the lecture, the permutation invariance criterion yields a class of putative ‘logical constants’ that are essentially only sensitive to the number of elements in classes of individuals. Thus, to hold the permutation invariance thesis essentially amounts to limiting the scope of logic to quantificational phenomena, which is controversial at best and possibly simply wrong. In this paper, I argue that permutation invariance is a misguided approach to the nature of logic because it is not an adequate formal explanans for the informal notion of the generality of logic. In particular, I discuss some cases of undergeneration of the criterion, i.e. the fact that it excludes from the realm of logic operators that we have good reason to regard as logical, especially some modal operators.

I examine the theory of consequentia of the medieval logician, John Buridan. Buridan advocates a strict commitment to what we now call proposition-tokens as the bearers of truth-value. The analysis of Buridan's theory shows that, within a token-based semantics, amendments to the usual notions of inference and consequence are made necessary, since pragmatic elements disrupt the semantic behaviour of propositions. In my reconstruction of Buridan's theory, I use some of the apparatus of modern two-dimensional semantics, such as two-dimensional matrices and (...) the distinction between the context of formation and the context of evaluation of utterances.

The paper argues that much of the difficulty with making progress on the issue of the normativity of logic for thought, as discussed in the literature, stems from a misapprehension of what logic is normative for. The claim is that, rather than mono-agent mental processes, logic in fact comprises norms for quite specific situations of multi-agent dialogical interactions, in particular special forms of debates. This reconceptualization is inspired by historical developments in logic and mathematics, in particular the pervasiveness of such (...) dialogical conceptions in the early days of logic in ancient Greece. The multi-agent, dialogical perspective then allows for the formulation of compelling 'bridge principles’ between the relation of logical consequence and dialogical normative principles, something that is notoriously difficult to achieve in a mono-agent setting pertaining exclusively to thought and belief. The upshot is also that the truth-preserving rules of logic generally do not have a primary normative bearing on mono-agent mental processes, and in this sense the paper sides with Harman's critique of the idea that logic has a normative import for thought and belief.

This book presents novel formalizations of three of the most important medieval logical theories: supposition, consequence and obligations. In an additional fourth part, an in-depth analysis of the concept of formalization is presented - a crucial concept in the current logical panorama, which as such receives surprisingly little attention.Although formalizations of medieval logical theories have been proposed earlier in the literature, the formalizations presented here are all based on innovative vantage points: supposition theories as algorithmic hermeneutics, theories of consequence analyzed (...) with tools borrowed from model-theory and two-dimensional semantics, and obligations as logical games. For this reason, this is perhaps the first time that these medieval logical theories are made fully accessible to the modern philosopher and logician who wishes to obtain a better grasp of them, but who has always been held back by the lack of appropriate ‘translations' into modern terms.Moreover, the book offers a reflection on the very nature of logic, a reflection that is prompted by the comparisons between medieval and modern logic, their similarities and dissimilarities. It is thus a contribution not only to the history of logic, but also to the philosophy of logic, the philosophy of language and semantics.The analysis of medieval logic is also relevant for the modern philosopher and logician in that, being the unifying methodology used across all disciplines at that time, logic really provided unity to science. It thus presents a unified model of scientific investigation, where logic plays the aggregating role. (shrink)

What does it mean to say that logic is formal? The short answer is: it means (or can mean) several different things. In this paper, I argue that there are (at least) eight main variations of the notion of the formal that are relevant for current discussions in philosophy and logic, and that they are structured in two main clusters, namely the formal as pertaining to forms, and the formal as pertaining to rules. To the first cluster belong the formal (...) as schematic; the formal as indifference to particulars; the formal as topic-neutrality; the formal as abstraction from intentional content; the formal as de-semantification. To the second cluster belong the formal as computable; the formal as pertaining to regulative rules; the formal as pertaining to constitutive rules. I analyze each of these eight variations, providing their historical background and raising related philosophical questions. The significance of this work of ?conceptual archeology? is that it may enhance clarity in debates where the notion of the formal plays a prominent role (such as debates where it is expected to play a demarcating role), but where it is oftentimes used equivocally and/or imprecisely.

Explication is the conceptual cornerstone of Carnap’s approach to the methodology of scientific analysis. From a philosophical point of view, it gives rise to a number of questions that need to be addressed, but which do not seem to have been fully addressed by Carnap himself. This paper reconsiders Carnapian explication by comparing it to a different approach: the ‘formalisms as cognitive tools’ conception. The comparison allows us to discuss a number of aspects of the Carnapian methodology, as well as (...) issues pertaining to formalization in general. We start by introducing Carnap’s conception of explication, arguing that there is a tension between his proposed criteria of fruitfulness and similarity; we also argue that his further desideratum of exactness is less crucial than might appear at first. We then bring in the general idea of formalisms as cognitive tools, mainly by discussing the reliability of so-called statistical prediction rules, i.e. simple algorithms used to make predictions across a range of areas. SPRs allow for a concrete instantiation of Carnap’s fruitfulness desideratum, which is arguably the most important desideratum for him. Finally, we elaborate on what we call the ‘paradox of adequate formalization’, which for the Carnapian corresponds to the tension between similarity and fruitfulness. We conclude by noting that formalization is an inherently paradoxical enterprise in general, but one worth engaging in given the ‘cognitive boost’ it affords as a tool for discovery. (shrink)

Argumentation is important for sharing knowledge and information. Given that the receiver of an argument purportedly engages first and foremost with its content, one might expect trust to play a negligible epistemic role, as opposed to its crucial role in testimony. I argue on the contrary that trust plays a fundamental role in argumentative engagement. I present a realistic social epistemological account of argumentation inspired by social exchange theory. Here, argumentation is a form of epistemic exchange. I illustrate my argument (...) with two real-life examples: vaccination hesitancy, and the undermining of the credibility of traditional sources of information by authoritarian politicians. (shrink)

The thought of François Jullien has made valuable contributions to contemporary philosophy, primarily by enriching the interpretation of certain classic themes through the uniqueness of ancient Chinese wisdom. This approach has revealed aspects that Western philosophy, with its metaphysics focused on being, has overlooked. Among these aspects, Jullien has drawn attention to how a series of resources of what could be called ‘Christian thought’ have remained unthought-of, at least from a philosophical perspective. The central question of this research is whether (...) this Christian logic represents just another resource, among several, that Jullien has utilized in his intellectual work, or if it also constitutes one of the fundamental sources of his own work and the beginnings of possible de-coincidence from the philosophy of being. The conclusions indicate a notable and indispensable presence of these Christian notions in his argumentative proposal, albeit without resorting to faith. This study will begin by reviewing the main theses of the French philosopher and, at the same time, will describe how he has been relating and discussing them with Christian doctrine. (shrink)

Ecological-enactive approaches to cognition aim to explain cognition in terms of the dynamic coupling between agent and environment. Accordingly, cognition of one’s immediate environment (which is sometimes labeled “basic” cognition) depends on enaction and the picking up of affordances. However, ecological-enactive views supposedly fail to account for what is sometimes called “higher” cognition, i.e., cognition about potentially absent targets, which therefore can only be explained by postulating representational content. This challenge levelled against ecological-enactive approaches highlights a putative explanatory gap between (...) basic and higher cognition. In this paper, we examine scientific cognition—a paradigmatic case of higher cognition—and argue that it shares fundamental features with basic cognition, for enaction and affordance selection are central to the scientific enterprise. Our argument focuses on modeling, and on how models promote scientific understanding. We base our argument on a non-representational account of scientific understanding and on the material engagement theory, for models are hereby conceived as material objects designed for scientific engagements. Having done so, we conclude that the explanatory gap is significantly less threatening to the ecological-enactive approach than it might appear. (shrink)

The paper investigates the propriety of applying the form versus matter distinction to arguments and to logic in general. Its main point is that many of the currently pervasive views on form and matter with respect to logic rest on several substantive and even contentious assumptions which are nevertheless uncritically accepted. Indeed, many of the issues raised by the application of this distinction to arguments seem to be related to a questionable combination of different presuppositions and expectations; this holds in (...) particular of the vexed issue of demarcating the class of logical constants. I begin with a characterization of currently widespread views on form and matter in logic, which I refer to as 'logical hylomorphism as we know it'—LHAWKI, for short—and argue that the hylomorphism underlying LHAWKI is mereological. Next, I sketch an overview of the historical developments leading from Aristotelian, non-mereological metaphysical hylomorphism to mereological logical hylomorphism (LHAWKI). I conclude with a reassessment of the prospects for the combination of hylomorphism and logic, arguing in particular that LHAWKI is not the only and certainly not the most suitable version of logical hylomorphism. In particular, this implies that the project of demarcating the class of logical constants as a means to define the scope and nature of logic rests on highly problematic assumptions. (shrink)

Genealogical anxiety is the worry that the origins of beliefs, once revealed to be influenced by “irrelevant” factors such as personal histories and circumstances of upbringing, will undermine or cast doubt on those beliefs. Discussions on these irrelevant influences in the epistemological literature have so far primarily focused on their contingency. But there is another issue that merits further examination: the fact that epistemic environments condition beliefs suggests that epistemic agency is significantly curtailed. I present a model of belief-forming processes (...) that highlights how networks of attention and trust/distrust influence these processes. The model suggests that, while there is a lot happening beyond our control that shapes what we come to believe, we still retain some degree of agency to the extent that we can rewire our networks of attention and trust/distrust. I conclude that, surprisingly, genealogical anxiety may in fact increase agency insofar as it may encourage critical resistance. (shrink)

It is well known that reductio ad absurdum arguments raise a number of interesting philosophical questions. What does it mean to assert something with the precise goal of then showing it to be false, i.e. because it leads to absurd conclusions? What kind of absurdity do we obtain? Moreover, in the mathematics education literature number of studies have shown that students find it difficult to truly comprehend the idea of reductio proofs, which indicates the cognitive complexity of these constructions. In (...) this paper, I start by discussing four philosophical issues pertaining to reductio arguments. I then briefly present a dialogical conceptualization of deductive arguments, according to which such arguments are best understood as a dialogue between two participants—Prover and Skeptic. Finally, I argue that many of the philosophical and cognitive difficulties surrounding reductio arguments are dispelled or at least further clarified once one adopts a dialogical perspective.

Since at least the 1980s, the role of adversariality in argumentation has been extensively discussed within different domains. Prima facie, there seem to be two extreme positions on this issue: argumentation should never be adversarial, as we should always aim for cooperative argumentative engagement; argumentation should be and in fact is always adversarial, given that adversariality is an intrinsic property of argumentation. I here defend the view that specific instances of argumentation are adversarial or cooperative to different degrees. What determines (...) whether an argumentative situation should be primarily adversarial or primarily cooperative are contextual features and background conditions external to the argumentative situation itself, in particular the extent to which the parties involved have prior conflicting or else convergent interests. To further develop this claim, I consider three teloi that are frequently associated with argumentation: the epistemic telos, the consensus-building telos, and the conflict management telos. I start with a brief discussion of the concepts of adversariality, cooperation, and conflict in general. I then sketch the main lines of the debates in the recent literature on adversariality in argumentation. Next, I discuss the three teloi of argumentation listed above in turn, emphasizing the roles of adversariality and cooperation for each of them. (shrink)

In The Enigma of Reason, Mercier and Sperber (M&S) present and defend their interactionist account of reason. In this piece, I discuss briefly the points of agreement between M&S and myself and, more extensively, the points of disagreement, most of which pertain to details of the evolutionary components of their account. I discuss in particular the purported modular nature of reason; their account of myside bias as an optimum/adaptation; and the claim that reason thus construed must be an individual‐level and (...) not a group‐level adaptation. In the final section, I offer brief considerations on an alternative account of reasoning, where the focus is on how sociocultural environments may tune the social production and evaluation of arguments.

This volume, the first dedicated and comprehensive companion to medieval logic, covers both the Latin and the Arabic traditions, and shows that they were in fact sister traditions, which both arose against the background of a Hellenistic heritage and which influenced one another over the centuries. A series of chapters by both established and younger scholars covers the whole period including early and late developments, and offers new insights into this extremely rich period in the history of logic. The volume (...) is divided into two parts, 'Periods and Traditions' and 'Themes', allowing readers to engage with the subject from both historical and more systematic perspectives. It will be a must-read for students and scholars of medieval philosophy, the history of logic, and the history of ideas. (shrink)

I argue that the medieval form of dialectical disputation known as obligationes can be viewed as a logical game of consistency maintenance. The game has two participants, Opponent and Respondent. Opponent puts forward a proposition P; Respondent must concede, deny or doubt, on the basis of inferential relations between P and previously accepted or denied propositions, or, in case there is none, on the basis of the common set of beliefs. Respondent loses the game if he concedes a contradictory set (...) of propositions. Opponent loses the game if Respondent is able to maintain consistency during the stipulated period of time. The obligational rules are here formalised by means of familiar notational devices, and the application of some game-theoretical concepts, such as (winning) strategy, moves, motivation, allows for an analysis of some crucial properties of the game. In particular, the primacy of inferential (syntactic) relations over semantic aspects and the dynamic character of obligations are outlined. (shrink)

El propósito del presente escrito es hacer un análisis de algunas defensas universalistas sobre el segundo argumento de Z13 el cual niega que el universal pueda ser forma y, de esta manera, que pueda ser substancia primera.

El segundo momento del análisis (...) consiste en mostrar una serie de distinciones importantes no trazadas del segundo argumento que conducen, nuevamente, a que el argumento universalista no sea consistente.

In describing numerosity as “a kind of ersatz number,” Clarke and Beck fail to consider a familiar and compelling definition of numerosity, which conceptualizes numerosity as the cognitive counterpart of the mathematical concept of cardinality; numerosity is the magnitude, whereas number is a scale through which numerosity/cardinality is measured. We argue that these distinctions should be considered.

Overdoing Democracy is an important contribution to the literature on (deliberative) democracy, as it offers a sobering diagnosis of the risks and pitfalls of (overdoing) democracy in the form of internal critique. But the book does not go far enough in its diagnosis because it is not sufficiently critical towards some of the basic assumptions of deliberative conceptions of democracy. In particular, Talisse does not sufficiently attend to the inevitable power struggles in a society, where different groups and individuals must (...) protect their own (often conflicting) interests instead of working towards a ‘common good.’ In this essay, I contrast two different visions of democracy and politics, one based on ideals of consensus and cooperation, and another on the inevitability of perennial conflict. I then briefly present an alternative to deliberative conceptions of democracy that has gained traction in recent decades, known as agonism. Next, I offer a short reconstruction of Talisse’s proposal, and finally I sketch a critical assessment of some of his main claims and assumptions from an agonistic perspective. (shrink)

Can arguments change minds? Philosophers like to think that they can. However, a wealth of empirical evidence suggests that arguments are not very efficient tools to change minds. What to make of the different assessments of the mind-changing potential of arguments? To address this issue, we must take into account the broader contexts in which arguments occur, in particular the propagation of messages across networks of attention, and the choices that epistemic agents must make between alternative potential sources of content (...) and information, which are very much influenced by perceptions of reliability and trustworthiness. Arguments can change minds, but only under conducive, favourable socio-epistemic conditions. (shrink)

In Bad Beliefs, Levy presents a picture of belief-forming processes according to which, on most matters of significance, we defer to reliable sources by relying extensively on cultural and social cues. Levy conceptualizes the kind of evidence provided by socio-cultural environments as higher-order evidence. But his notion of higher-order evidence seems to differ from those available in the epistemological literature on higher-order evidence, and this calls for a reflection on how exactly social and cultural cues are/count as/provide higher-order evidence. In (...) this paper, I draw on the three-tiered model of epistemic exchange that I have been developing recently, which highlights the centrality of relations of attention and trust in belief-forming processes, to explicate how social and cultural cues provide higher-order evidence. I also argue that Levy’s account fails to sufficiently address the issue of strategic actors who have incentives to pollute epistemic environments for their benefit, and more generally the power struggles, incentives, and competing interests that characterize human sociality. Levy’s attempted reduction of the political to the epistemic ultimately fails, but his account of social and cultural cues as higher-order evidence offers an insightful perspective on epistemic social structures.

In the scholarship on medieval logic and semantics of the last decades, Ockham’s theory of supposition is probably the most extensively studied version of such theories; yet, it seems that we still do not fully understand all its intricacies. In this paper, I focus on a phrase that occurs countless times throughout Ockham’s writings, but in particular in the sections dedicated to supposition in the Summa logicae: the phrase ‘denotatur’. I claim that an adequate understanding of the role of the (...) concept of denotatur within Ockham’s supposition theory shall yield a deeper understanding of the theory as a whole. Here, I first examine a few uses of the term ‘denotatur’ and its variants by other authors. I then turn to Ockham: first I briefly mention some uses of the term in contexts other than his theory of supposition. Following that, I focus on his supposition theory, in particular on how ‘denotatur’ allows him to deal with two crucial puzzles, namely the supposition of empty terms and the supposition of terms in false affirmative propositions. The treatment of these two puzzles suggests that Ockham’s theory of supposition must be understood as a theory chiefly intended for the generation of the meanings of propositions. (shrink)

Thomas Bradwardine makes much of the fact that his solution to the insolubles is in accordance with Aristotle's diagnosis of the fallacy in the Liar paradox as that of secundum quid et simpliciter. Paul Spade, however, claims that this invocation of Aristotle by Bradwardine is purely "honorary" in order to confer specious respectability on his analysis and give it a spurious weight of authority. Our answer to Spade follows Bradwardine's response to the problem of revenge: any proposition saying of itself (...) that it is false says more than does Bradwardine's proposition saying of it that it is false, and so follows from that other proposition only in respect of part of what it says, and not simpliciter.

We investigate the philosophical significance of the existence of different semantic systems with respect to which a given deductive system is sound and complete. Our case study will be Corcoran's deductive system D for Aristotelian syllogistic and some of the different semantic systems for syllogistic that have been proposed in the literature. We shall prove that they are not equivalent, in spite of D being sound and complete with respect to each of them. Beyond the specific case of syllogistic, the (...) goal is to offer a general discussion of the relations between informal notions—in this case, an informal notion of deductive validity—and logical apparatuses such as deductive systems and (model-theoretic or other) semantic systems that aim at offering technical, formal accounts of informal notions. Specifically, we will be interested in Kreisel's famous 'squeezing argument'; we shall ask ourselves what a plurality of semantic systems (understood as classes of mathematical structures) may entail for the cogency of specific applications of the squeezing argument. More generally, the analysis brings to the fore the need for criteria of adequacy for semantic systems based on mathematical structures. Without such criteria, the idea that the gap between informal and technical accounts of validity can be bridged is put under pressure. (shrink)
