Cet ouvrage interroge les articulations problématiques entre art, flux et contemporain, à partir de pratiques artistiques actuelles où interviennent le quotidien, le sociologique et le collectif. Traversé par des flux de toute sorte, le monde contemporain soulève la question de sa représentabilité, alors que les artistes ont, depuis toujours, éprouvé le besoin de se mettre en adéquation avec lui. Comment en effet montrer ce qui sans cesse se meut? Pourquoi suivre les mouvances du monde? Et finalement, que peut l'art d'aujourd'hui? (...) Il s'agit pour les artistes d'adopter une position de contemporanéité car toute observation du monde, fût-elle opérée sur un mode contemplatif, ne peut être l'objet de l'inactif et de l'inopérant. C'est pourquoi "devenir contemporain" est une nécessité, une injonction politique et éthique aussi bien qu'esthétique. Il nous faut dès lors entreprendre une "esthétique du contemporain", elle qui nous portera vers un "contemporain de l'esthétique" guidé par les flux et les devenirs. (shrink)

Robert Sinclair’s *Quine, Conceptual Pragmatism, and the Analytic-Synthetic Distinction* persuasively argues that Quine’s epistemology was deeply influenced by C. I. Lewis’s pragmatism. Sinclair’s account raises the question why Quine himself frequently downplayed Lewis’s influence. Looking back, Quine has always said that Rudolf Carnap was his “greatest teacher” and that his 1933 meeting with the German philosopher was his “first experience of sustained intellectual engagement with anyone of an older generation” (1970, 41; 1985, 97-8, my emphasis). Quine’s autobiographies contain only a (...) handful of biographical references to Lewis and he regularly soft-pedaled the latter’s influence in private correspondence. In this note, I discuss some archival evidence that helps us better understand Quine’s reluctance to acknowledge Lewis’s influence. I contextualize the relation between Lewis and Quine and argue that the latter viewed his teacher as a retrograde force in modern epistemology, impeding the more rigorous approach that Carnap had been developing in Europe. Next, I briefly discuss Lewis’s contribution to the development of scientific philosophy in the United States and argue that Quine underestimated his teacher’s role in this process. In doing so, I hope to show that Quine’s zealous commitment to Carnap’s approach negatively affected his assessment of Lewis’s influence, thereby supplementing Sinclair’s praiseworthy reconstruction with an explanation of why Quine himself underestimated Lewis’s role.

Carnap and Quine first met in the 1932-33 academic year, when the latter, fresh out of graduate school, visited the key centers of mathematical logic in Europe. In the months that Carnap was finishing his Logische Syntax der Sprache, Quine spent five weeks in Prague, where they discussed the manuscript “as it issued from Ina Carnap’s typewriter”. The philosophical friendship that emerged in these weeks would have a tremendous impact on the course of analytic philosophy. Not only did the meetings (...) effectively turn Quine into Carnap's disciple, they also paved the way for their seminal debates about meaning, language, and ontology---the very discussions that would change the course of analytic philosophy in the decades after the Second World War. -/- Yet surprisingly little is known about these first meetings. Although Quine has often acknowledged the impact of his Prague visit, there appears to be little information about these first encounters, except for the fact that the Quines “were overwhelmed by the kindness of the Carnaps” and that it was Quine’s “most notable experience of being intellectually fired by a living teacher”. Neither their correspondence nor their autobiographies offer a detailed account of these meetings. In this paper, I shed new light on Carnap’s and Quine’s first encounters by examining a set of previously unexplored material from their personal and academic archives. Why did Quine decide to visit Carnap? What did they discuss? And in what ways did the meetings affect Quine’s philosophical development? In what follows, I address these questions by means of a detailed reconstruction of Quine’s year in Europe based on a range of letters, notes, and reports from the early 1930s. (shrink)

The emotions are at the centre of our lives and, for better or worse, imbue them with much of their significance. The philosophical problems stirred up by the existence of the emotions, over which many great philosophers of the past have laboured, revolve around attempts to understand what this significance amounts to. Are emotions feelings, thoughts, or experiences? If they are experiences, what are they experiences of? Are emotions rational? In what sense do emotions give meaning to what surrounds us? (...) -/- The Emotions: A Philosophical Introduction introduces and explores these questions in a clear and accessible way. The authors discuss the following key topics: -/- the diversity and unity of the emotions the relations between emotion, belief and desire the nature of values the relations between emotions and perceptions emotions viewed as evaluative attitudes the link between emotions and evaluative knowledge the nature of moods, sentiments, and character traits. -/- Including chapter summaries and guides to further reading, The Emotions: A Philosophical Introduction is an ideal starting point for any philosopher or student studying the emotions. It will also be of interest to those in related disciplines such as psychology and the social sciences. (shrink)

Susanne K. Langer is best known as a philosopher of culture and student of Ernst Cassirer. In this chapter, however, I argue that this standard picture ignores her contributions to the development of analytic philosophy in the 1920s and 1930s. I reconstruct the reception of Langer’s first book *The Practice of Philosophy*—arguably the first sustained defense of analytic philosophy by an American philosopher—and describe how prominent European philosophers of science such as Moritz Schlick, Rudolf Carnap, and Herbert Feigl viewed her (...) as one of the most important allies in the United States. In the second half of this chapter, I turn to Langer’s best-selling *Philosophy in a New Key* and reconstruct her attempts to broaden the scope of the, by then, rapidly growing U.S. analytic movement. I argue that her book anticipated various developments in analytic philosophy but was largely ignored by her former colleagues. I end the chapter by offering some clues as to why New Key did not incite the same laudatory responses from analytic philosophers as her earlier work. (shrink)

Quine's argument for a naturalized epistemology is routinely perceived as an argument from despair: traditional epistemology must be abandoned because all attempts to deduce our scientific theories from sense experience have failed. In this paper, I will show that this picture is historically inaccurate and that Quine's argument against first philosophy is considerably stronger and subtler than the standard conception suggests. For Quine, the first philosopher's quest for foundations is inherently incoherent; the very idea of a self-sufficient sense datum language (...) is a mistake, there is no science-independent perspective from which to validate science. I will argue that a great deal of the confusion surrounding Quine's argument is prompted by certain phrases in his seminal ‘Epistemology Naturalized’. Scrutinizing Quine's work both before and after the latter paper provides a better key to understanding his remarkable views about the epistemological relation between theory and evidence. (shrink)

Is shame social? Is it superficial? Is it a morally problematic emotion? Researchers in disciplines as different as psychology, philosophy, and anthropology have thought so. But what is the nature of shame and why are claims regarding its social nature and moral standing interesting and important? Do they tell us anything worthwhile about the value of shame and its potential legal and political applications? -/- In this book, Julien Deonna, Raffaele Rodogno, and Fabrice Teroni propose an original philosophical account (...) of shame aimed at answering these questions. The book begins with a detailed examination of the evidence and arguments that are taken to support what they call the two dogmas about shame: its alleged social nature and its morally dubious character. Their analysis is conducted against the backdrop of a novel account of shame and ultimately leads to the rejection of these two dogmas. On this account, shame involves a specific form of negative evaluation that the subject takes towards herself: a verdict of incapacity with regard to values to which she is attached. One central virtue of the account resides in the subtle manner it clarifies the ways in which the subject's identity is at stake in shame, thus shedding light on many aspects of this complex emotion and allowing for a sophisticated understanding of its moral significance. -/- This philosophical account of shame engages with all the current debates on shame as they are conducted within disciplines as varied as ethics, moral, experimental, developmental and evolutionary psychology, anthropology, legal studies, feminist studies, politics and public polic.

Historians have shown that philosophical discussions about the implications of relativity significantly shaped the development of European philosophy of science in the 1920s. Yet little is known about American debates from this period. This paper maps the first responses to Einstein’s theory in three U.S. philosophy journals and situates these papers within the local intellectual climate. We argue that these discussions (1) stimulated the development of a distinctly American branch of philosophy of science and (2) paved the way for the (...) logical empiricists, who emigrated to the United States in the years before World War II.

One puzzle concerning highly idealized models is whether they explain. Some suggest they provide so-called ‘how-possibly explanations’. However, this raises an important question about the nature of how-possibly explanations, namely what distinguishes them from ‘normal’, or how-actually, explanations? I provide an account of how-possibly explanations that clarifies their nature in the context of solving the puzzle of model-based explanation. I argue that the modal notions of actuality and possibility provide the relevant dividing lines between how-possibly and how-actually explanations. Whereas how-possibly (...) explanations establish claims of possible explanations, how-actually explanations establish claims of actual ones. Models, in turn, simply provide evidence for these claims. (shrink)

Models typically have actual, existing targets. However, some models are viewed as having non-actual targets. I argue that this interpretation comes at various costs and propose an alternative that fares better along two dimensions: (1) agreement with practice and (2) ontological and epistemological parsimony. My proposal is that many of these models actually have actual targets.

According to logical inferentialists, the meanings of logical expressions are fully determined by the rules for their correct use. Two key proof-theoretic requirements on admissible logical rules, harmony and separability, directly stem from this thesis—requirements, however, that standard single-conclusion and assertion-based formalizations of classical logic provably fail to satisfy :1035–1051, 2011). On the plausible assumption that our logical practice is both single-conclusion and assertion-based, it seemingly follows that classical logic, unlike intuitionistic logic, can’t be accounted for in inferentialist terms. In (...) this paper, I challenge orthodoxy and introduce an assertion-based and single-conclusion formalization of classical propositional logic that is both harmonious and separable. In the framework I propose, classicality emerges as a structural feature of the logic. (shrink)

I develop the concept of hypothetical interpretation to give an account of certain problematic interpretive practices within a broadly Gricean framework. These practices attempt to find neither speaker nor linguistic meaning but rather, seek to discover such things as the unconscious beliefs of a text’s producer. In developing the concept of hypothetical interpretation, I consider in particular the question of their plausibility. I show how the plausibility of a hypothetical interpretation can be taken as providing evidence about a speaker’s noncommunicative (...) mental state, and how psychoanalytic interpretive practices and similar “hermeneutics of suspicion” rely upon such evidence.

The rise of the natural sciences in the 16th century has strongly influenced the way in which philosophers reflect on activities that confer meaning to human life and, more specifically, on the religious and ethical phenomenon. Measured by the ideal of rationality as can be found in the sciences, each act of conferring meaning is seen either as a specific form of irrational behaviour which can nevertheless be considered as fulfilling a need for psychic convenience, or as something in line (...) with the cognitive demands of science – many forms of ‘holism’ are an example of this. Burms and De Dijn indicate that every act of conferring meaning is ‘sui generis’ and cannot be reduced neither to an utilitarian nor to a cognitive interest. Mainly this last point is clarified in the first part of this article. The thesis that there is a divide or a gap between intellectual knowledge and life, between knowing and meaning is shown by referring to a twofold insight. Intellectual knowledge in itself cannot be a source of meaning. In opposition to the thesis of Boëthius knowledge cannot – according to De Dijn – give any consolation. What’s more: the craving for meaning cannot, as Wittgenstein remarked, be reduced to a craving for information. Religion and morality must, as disciplines of meaning, be described as original activities completely distinct from scientific insight. – In the same line Paul Moyaert points, inspired by Lacan’s analysis of desire, to the therapeutic role of the symbolic order and consequently to the priority the outer has on the inner. Since the Reformation and mainly since Kant the religious phenomenon threatens to be reduced to a moral opinion and its varieties. Moyaert wants to ‘de-protestantize’ reflection on religion, which involves according to him taking religion away from the order of the inner and taking it back home to the order of the outer.

This paper reconstructs the origins of Gettier-style epistemology, highlighting the philosophical and methodological debates that led to its development in the 1960s. Though present-day epistemologists assume that the search for necessary and sufficient conditions for knowledge began with Gettier’s 1963 argument against the JTB-definition, I show that this research program can be traced back to British discussions about knowledge and analysis in the 1940s and 1950s. I discuss work of, among others, Bertrand Russell, G. E. Moore, A. J. Ayer, Norman (...) Malcom, and A. D. Woozley, showing how exchanges between different schools of analytic philosophy gave rise to new ideas about the nature of knowledge and analysis. Finally, I turn to Gettier's intellectual development and argue that his paper was influenced by some of these debates, suggesting that even his interpretation of Plato’s definition of knowledge can be traced back to discussions in this period.

During the past few decades, a radical shift has occurred in how philosophers conceive of the relation between science and philosophy. A great number of analytic philosophers have adopted what is commonly called a ‘naturalistic’ approach, arguing that their inquiries ought to be in some sense continuous with science. Where early analytic philosophers often relied on a sharp distinction between science and philosophy—the former an empirical discipline concerned with fact, the latter an a priori discipline concerned with meaning—philosophers today largely (...) follow Willard Van Orman Quine (1908-2000) in his seminal rejection of this distinction. -/- This book offers a comprehensive study of Quine’s naturalism. Building on Quine’s published corpus as well as thousands of unpublished letters, notes, lectures, papers, proposals, and annotations from the Quine archives, this book aims to reconstruct both the nature (chapters 2-4) and the development (chapter 5-7) of his naturalism. As such, this book aims to contribute to the rapidly developing historiography of analytic philosophy, and to provide a better, historically informed, understanding of what is philosophically at stake in the contemporary naturalistic turn.

Logical positivism is often characterized as a set of naive doctrines on meaning, method, and metaphysics. In recent decades, however, historians have dismissed this view as a gross misinterpretation. This new scholarship raises a number of questions. When did the standard reading emerge? Why did it become so popular? And how could commentators have been so wrong? This essay reconstructs the history of a “caricature” and rejects the hypothesis that it was developed by ill-informed Anglophone scholars who failed to appreciate (...) the subtleties of European scientific philosophy. It argues that the received view has a more complicated history and was frequently promoted by the European positivists themselves. The essay shows that the view has roots in both American and European scientific philosophy and emerged as a result of the complex interplay between the two communities in the years before the intellectual migration.

The aim of this article is to demonstrate the usefulness of qualitative research for studying the ethics of care, bringing to light the lived experience of health care recipients, together with the importance of methods that allow reconstruction of the processes underlying this lived experience. Lived experiences of families being approached for organ donation, parents facing the imminent death of their child and patients being treated using stem cell transplantation are used to illustrate how ethical principles are differentiated, modified or (...) contradicted by the narrative context of persons concerned. The integration of empirical data into ethics will help caregivers in their ethical decision making and may enrich care ethics as a narrative and interpretative field. (shrink)

It is sometimes held that rules of inference determine the meaning of the logical constants: the meaning of, say, conjunction is fully determined by either its introduction or its elimination rules, or both; similarly for the other connectives. In a recent paper, Panu Raatikainen (2008) argues that this view - call it logical inferentialism - is undermined by some "very little known" considerations by Carnap (1943) to the effect that "in a definite sense, it is not true that the standard (...) rules of inference" themselves suffice to "determine the meanings of [the] logical constants" (p. 2). In a nutshell, Carnap showed that the rules allow for non-normal interpretations of negation and disjunction. Raatikainen concludes that "no ordinary formalization of logic ... is sufficient to `fully formalize' all the essential properties of the logical constants" (ibid.). We suggest that this is a mistake. Pace Raatikainen, intuitionists like Dummett and Prawitz need not worry about Carnap's problem. And although bilateral solutions for classical inferentialists - as proposed by Timothy Smiley and Ian Rumfitt - seem inadequate, it is not excluded that classical inferentialists may be in a position to address the problem too.

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief has it if and only if it (...) has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

In this paper, we develop a fresh understanding of the sense in which emotions are evaluations. We argue that we should not follow mainstream accounts in locating the emotion–value connection at the level of content and that we should instead locate it at the level of attitudes or modes. We begin by explaining the contrast between content and attitude, a contrast in the light of which we review the leading contemporary accounts of the emotions. We next offer reasons to think (...) that these accounts face substantial problems since they locate the link emotions bear to values at the level of content. This provides the incentive to pursue an alternative approach according to which emotions qualify as evaluations because they are specific types of attitudes, an approach we substantiate by appealing to felt bodily stances. We conclude by considering two reasons why this approach may be resisted; they respectively pertain to the alleged impossibility of drawing the attitude–content contrast in the case of the emotions and to the suspicion that so doing raises qualia-related worries.

Julien Tricard tackles the abductive solution to the problem of induction. In order to best explain the regularities that can be observed in nature, should one assume that they necessarily result from natural laws, without which they would be improbable cosmic coincidences? By examining David Armstrong's and John Foster's versions of this inference, Julien Tricard shows that it is based on the confusion of two incompatible concepts of “regularity”. From this he derives a conception of induction that is (...) neither the empiricists’ factual generalization, nor the abduction of nomic necessities from observed regularities, but the operation of constituting particular facts as regular instances of laws.

Abstract The content of an emotion, unlike the content of a perception, is directly dependent on the motivational set of the subject experiencing the emotion. Given the instability of this motivational set, it might be thought that there is no sense in which emotions can be said to pick up information about the environment in the same way that perception does. Whereas it is admitted that perception tracks for us what is the case in the environment, no such tracking relation, (...) it is argued, holds between one's emotions and what they are about. It is to this worry – that the construal of the emotions as perceptions inevitably raises – that this paper tries to respond. In this paper, I suggest that when it is realized that one dimension of perception itself is directly dependent on the perceiver's perspective on her environment, then emotion, which is also essentially perspectival in this sense, bears the comparison with perception very well. After having clarified the nature and the role that perspective plays in perception, I argue that, in the case of emotions, the same perspectival role can be played by agents’ long-standing evaluative tendencies and character traits. The resulting conception of emotion as perception is then tested against possible objections. (shrink)

Since Saul Kripke’s influential work in the 1970s, the revisionary approach to semantic paradox—the idea that semantic paradoxes must be solved by weakening classical logic—has been increasingly popular. In this paper, we present a new revenge argument to the effect that the main revisionary approaches breed new paradoxes that they are unable to block.

For Hannah Arendt, authority is the shape educational responsibility assumes. In our time, authority in Arendt’s sense is under pressure. The figure of Greta Thunberg shows the failure of adult generations, taken collectively, to take responsibility for the world and present and future generations of newcomers. However, in reflecting on Arendt’s use of authority, we argue that her account of authority also requires amendments. Arendt’s situating of educational authority in-between past and future adequately captures its temporal dimension. We make explicit (...) another, spatial, dimension: authority in-between world and earth. Arendt’s neglect of the material earth also has implications for the relational dimension of authority. Arendt’s authority depends on a dichotomy between the private and the public sphere. This is problematic. First, we agree with Arendt’s feminist critics that the personal can be made into the site of the political. Second, we point once more to Thunberg, the child, taking the public stage, thereby contesting the division between public and private. In response, we situate the relational dimension of authority in-between private and public. The three dimensions of educational authority taken together imply that it is situated in-between domains that cannot be reduced to each other or taken as absolutes: past and future, world and earth, and the private and public sphere. This brings us to our concept of ambiguous authority, which expresses the Arendtian nature of our reflections and the ways in which we seek to renew her original insights on educational authority.

Widespread preservation of fossilized biomolecules in many fossil animals has recently been reported in six studies, based on Raman microspectroscopy. Here, we show that the putative Raman signatures of organic compounds in these fossils are actually instrumental artefacts resulting from intense background luminescence. Raman spectroscopy is based on the detection of photons scattered inelastically by matter upon its interaction with a laser beam. For many natural materials, this interaction also generates a luminescence signal that is often orders of magnitude more (...) intense than the light produced by Raman scattering. Such luminescence, coupled with the transmission properties of the spectrometer, induced quasi‐periodic ripples in the measured spectra that have been incorrectly interpreted as Raman signatures of organic molecules. Although several analytical strategies have been developed to overcome this common issue, Raman microspectroscopy as used in the studies questioned here cannot be used to identify fossil biomolecules.

In this article, the authors examine and debate the categories of emotions, moods, temperaments, character traits and sentiments. They define them and offer an account of the relations that exist among the phenomena they cover. They argue that, whereas ascribing character traits and sentiments (dispositions) is to ascribe a specific coherence and stability to the emotions (episodes) the subject is likely to feel, ascribing temperaments (dispositions) is to ascribe a certain stability to the subject's moods (episodes). The rationale for this (...) distinction, the authors claim, lies in the fact that, whereas appeal to character traits or sentiments in explanation is tantamount to making sense of a given behaviour in terms of an individual's specific evaluative perspective - as embodied in this individual's emotional profile - appeal to temperaments makes sense of it independently of any such evaluative perspective.

Taking our lead from Solomon’s emphasis on the importance of the intentional object of emotion, we review the history of repeated attempts to make this object disappear. We adduce evidence suggesting that in the case of James and Schachter, the intentional object got lost unintentionally. By contrast, modern constructivists seem quite determined to deny the centrality of the intentional object in accounting for the occurrence of emotions. Griffiths, however, downplays the role objects have in emotion noting that these do not (...) qualify as intentional. We argue that these disappearing acts, deliberate or not, generate fruitless debate and add little to the advancement of our understanding of emotion as an adaptive mechanism to cope with events that are relevant to an organism’s life.

Abstract:We analyzed co-citation patterns in 332,498 articles published in Anglophone psychology journals between 1946 and 1990 to estimate (1) when cognitive psychology first emerged as a clearly delineated subdiscipline, (2) how fast it grew, (3) to what extent it replaced other (e.g., behaviorist) approaches to psychology, (4) to what degree it was more appealing to scholars from a younger generation, and (5) whether it was more interdisciplinary than alternative traditions. We detected a major shift in the structure of co-citation networks (...) between approximately 1955 and 1975 and draw novel conclusions about the developments commonly referred to as "the cognitive turn.".

Tarski's Undefinability of Truth Theorem comes in two versions: that no consistent theory which interprets Robinson's Arithmetic (Q) can prove all instances of the T-Scheme and hence define truth; and that no such theory, if sound, can even express truth. In this note, I prove corresponding limitative results for validity. While Peano Arithmetic already has the resources to define a predicate expressing logical validity, as Jeff Ketland has recently pointed out (2012, Validity as a primitive. Analysis 72: 421-30), no theory (...) which interprets Q closed under the standard structural rules can define nor express validity, on pain of triviality. The results put pressure on the widespread view that there is an asymmetry between truth and validity, viz. that while the former cannot be defined within the language, the latter can. I argue that Vann McGee's and Hartry Field's arguments for the asymmetry view are problematic. (shrink)

It is often argued that fully structural theories of truth and related notions are incapable of expressing a nonstratified notion of defectiveness. We argue that recently much-discussed non-contractive theories suffer from the same expressive limitation, provided they identify the defective sentences with the sentences that yield triviality if they are assumed to satisfy structural contraction.

When spelled out properly infallibilism is a viable and even attractive view. Because it has long been summary dismissed, however, we need a guide on how to properly spell it out. The guide has to fulfil four tasks. The first two concern the nature of knowledge: to argue that infallible belief is necessary, and that it is sufficient, for knowledge. The other two concern the norm of belief: to argue that knowledge is necessary, and that it is sufficient, for justified (...) certainty. With such a guide in hand infallibilism can be evaluated on its own merits. The most controversial parts are the first and fourth. The idea that knowledge requires infallible belief is thought to be excessively sceptical. The idea that knowledge warrants certainty is thought to be excessively dogmatic. The present paper addresses the first. It argues that knowledge requires infallible belief. (shrink)

This chapter introduces inferential role semantics (IRS) and some of the challenges it faces. It also introduces inferentialism and places it into the wider context of contemporary philosophy of language. The chapter focuses on what is standardly considered both the most important test case for and the most natural application of IRS: logical inferentialism, the view that the meanings of the logical expressions are fully determined by the basic rules for their correct use, and that to understand a logical expression (...) is to use it in accordance with the appropriate rules. It discusses some of the benefits of logical inferentialism, chiefly with regard to the epistemology of logic, and considers a number of objections. The chapter critically examines Robert Brandom's inferentialism about linguistic and conceptual content in general. Finally, it considers a number of general objections to IRS and possible responses on the inferentialist's behalf. (shrink)

How can we use models to understand real phenomena if models misrepresent the very phenomena we seek to understand? Some accounts suggest that models may afford understanding by providing causal knowledge about phenomena via how-possibly explanations. However, general equilibrium models, for example, pose a challenge to this solution since their contribution appears to be purely mathematical results. Despite this, practitioners widely acknowledge that it improves our understanding of the world. I argue that the Arrow–Debreu model provides a mathematical how-possibly explanation (...) which establishes claims of mathematical dependence. The account developed reveals how mathematical knowledge can inform claims about the world, allow ‘what-if-things-had-been-different’ inferences, and thus improve our understanding. (shrink)

Argumentation has been an important topic in knowledge representation, reasoning and multi-agent systems during the last twenty years. In this paper, we propose a new abstract framework where arguments are associated with a strength, namely a quantitative information which is used to determine whether an attack between arguments succeeds or not. Our Strength-based Argumentation Framework combines ideas of Preference-based and Weighted Argumentation Frameworks in an original way, which permits to define acceptability semantics sensitive to the existence of accruals between arguments. (...) The question of accruals arises in situations where several arguments defending the same position against another argument are unable to individually defeat this argument, but could do it collectively if they combine their strengths. We investigate some of the theoretical and computational properties of our new framework and semantics, and present a reasoning algorithm that is based on a translation of the problem into pseudo-boolean constraint satisfaction. This paper proposes an intuitive framework which allows strength compensations in an argumentation context where attacks may not succeed, completed by an approach which detects accruals throughout the reasoning process without requiring the elicitation of all compensatory combinations of arguments as an input.
