The International Competition on Computational Models of Argumentation (ICCMA) focuses on reasoning tasks in abstract argumentation frameworks. Submitted solvers are tested on a selected collection of benchmark instances, including artificially generated argumentation frameworks and some frameworks formalizing real-world problems. This paper presents the novelties introduced in the organization of the Third (2019) and Fourth (2021) editions of the competition. In particular, we proposed new tracks to competitors, one dedicated to dynamic solvers (i.e., solvers that incrementally compute solutions of frameworks obtained (...) by incrementally modifying original ones) in ICCMA’19 and one dedicated to approximate algorithms in ICCMA’21. From the analysis of the results, we noticed that i) dynamic recomputation of solutions leads to significant performance improvements, ii) approximation provides much faster results with satisfactory accuracy, and iii) classical solvers improved with respect to previous editions, thus revealing advancement in state of the art.

In this paper, I discuss the similarity between Wittgenstein’s use of thought experiments and Relativity Theory. I begin with introducing Wittgenstein’s idea of “thought experiments” and a tentative classification of different kinds of thought experiments in Wittgenstein’s work. Then, after presenting a short recap of some remarks on the analogy between Wittgenstein’s point of view and Einstein’s, I suggest three analogies between the status of Wittgenstein’s mental experiments and Relativity theory: the topics of time dilation, the search for invariants, and (...) the role of measuring tools in Special Relativity. This last point will help to better define Wittgenstein’s idea of description as the core of his philosophical enterprise. (shrink)

Chaque fois que nous "donnons forme" à quelque chose, cette représentation nous figure, par signes, l'objet évoqué, mais nous confirme également qu'il ne s'agit que d'un simulacre. D'où le besoin, à chaque époque, de créer du vivant pour pallier cette déception : tel est le sens du mythe de Pygmalion. Ce livre s'organise donc autour de deux pôles : d'un côté la nécessité de figurer, et de figurer l'acte même de la perception (voir le chapitre "Un oeil immense artificiel") ; (...) de l'autre, l'impératif de dépasser le signe. Il s'agit d'un défi radical, qui concerne l'avenir même des arts. C'est la raison de ce titre, A vif, qui témoigne d'un "coup d'oeil" : un regard et une incision pratiquée à vif dans l'objet, un désir de définitif qui ne caresse plus la forme, mais qui pénètre, met à nu, éviscère dans les paroles et dans les actes. Dedans et derrière l'oeil, comme dans l'un des plus impassibles traités d'anatomie du Cinquecento. Aujourd'hui, est-il encore vif notre oeil qui cherche le vivant? N'est-il pas lui-même défiguré par l'informe qui s'est logé en nous? Où est la pupilla viva qui illumine le Paradis et qui, de Dante à Baudelaire, a animé, de longs siècles durant, tant de quête mentale? Il faut remonter à ces origines, parcourir les espaces séculaires et sidéraux dans lesquels le cosmos était ordre, beauté, compréhension ; où, justement, il était nécessaire de "captiver les yeux pour avoir l'âme". Cet essai se voudrait une parabole déployée au fil de l'ardente soif humaine d'"exorbiter", de brûler la distance du point de vue, pour accéder, maintenant et à jamais, au vivant. (shrink)

Many of the computing systems programmed using Machine Learning are opaque: it is difficult to know why they do what they do or how they work. Explainable Artificial Intelligence aims to develop analytic techniques that render opaque computing systems transparent, but lacks a normative framework with which to evaluate these techniques’ explanatory successes. The aim of the present discussion is to develop such a framework, paying particular attention to different stakeholders’ distinct explanatory requirements. Building on an analysis of “opacity” from (...) philosophy of science, this framework is modeled after accounts of explanation in cognitive science. The framework distinguishes between the explanation-seeking questions that are likely to be asked by different stakeholders, and specifies the general ways in which these questions should be answered so as to allow these stakeholders to perform their roles in the Machine Learning ecosystem. By applying the normative framework to recently developed techniques such as input heatmapping, feature-detector visualization, and diagnostic classification, it is possible to determine whether and to what extent techniques from Explainable Artificial Intelligence can be used to render opaque computing systems transparent and, thus, whether they can be used to solve the Black Box Problem.

The place of God in Nietzsche’s thought remains central and controversial. Nietzsche’s proclamation of 'the death of God' is one of the most famous slogans in modern philosophy, seeming to encapsulate the nineteenth-century loss of religious faith in the affirmation that God has "turned out to be our oldest lie" and yet the nature of Nietzsche’s own ‘theology’ is far from clear. This volume engages with Nietzsche’s arguments about God, theology, and religion. The volume extends the discussion to an engagement (...) of Nietzsche with alternative models of God, with ancient Greek religions, and with discussions of diversity in dis/conjunction with religion. The chapters examine Nietzsche’s genealogy of religion and his claims about the place of God and theology in the history of Western thought, as well as his engagements with alternative conceptions of God. The volume also examines the historical and contemporary reception of Nietzsche’s arguments about God by religious and non-religious thinkers, asking to what extent Nietzsche’s philosophy of God speaks to the challenges of today's globalized philosophy and religion.

The received view of dynamical explanation is that dynamical cognitive science seeks to provide covering law explanations of cognitive phenomena. By analyzing three prominent examples of dynamicist research, I show that the received view is misleading: some dynamical explanations are mechanistic explanations, and in this way resemble computational and connectionist explanations. Interestingly, these dynamical explanations invoke the mathematical framework of dynamical systems theory to describe mechanisms far more complex and distributed than the ones typically considered by philosophers. Therefore, contemporary dynamicist (...) research reveals the need for a more sophisticated account of mechanistic explanation. (shrink)

Models developed using machine learning are increasingly prevalent in scientific research. At the same time, these models are notoriously opaque. Explainable AI aims to mitigate the impact of opacity by rendering opaque models transparent. More than being just the solution to a problem, however, Explainable AI can also play an invaluable role in scientific exploration. This paper describes how post-hoc analytic techniques from Explainable AI can be used to refine target phenomena in medical science, to identify starting points for future (...) investigations of causal relationships, and to generate possible explanations of target phenomena in cognitive science. In this way, this paper describes how Explainable AI—over and above machine learning itself—contributes to the efficiency and scope of data-driven scientific research. (shrink)

Our research addresses the issue of teaching and learning concepts in science education as an empirical question. We study the process of conceptualization by closely examining the unfolding of classroom lesson sequences. We situate our work within the practice turn line of research on epistemic practices in science education. We also adopt a practice turn approach when it comes to the learning of concepts, as we consider conceptualization as being inherent within epistemic practices. In our work, pedagogical practices are modeled (...) as learning games and epistemic practices in science education are characterized as enacted epistemic games emerging through the unfolding of learning games. Science practices are modeled as source epistemic games since they are the source of the knowledge at stake in pedagogical practices. From this point, we examine closely how playing learning games can enable students to play enacted epistemic games and then in turn the source epistemic games at the core of conceptual understanding. Thus, the main contribution of this paper is to link pedagogical practices to epistemic practices in science education and to science practices in general. Our method is consistent with this epistemological framework as our case study on the concept of earthquakes in a 5th grade classroom sequence illustrates. Following an investigation of two experienced teachers and their classes during a teaching unit, our analysis shows how teaching effectiveness is determined by a dialectic. This entails on the one hand a didactic continuity between learning games and enacted epistemic games and, on the other, an epistemic continuity between enacted epistemic games and source epistemic games.

ABSTRACTGeography must be conceived in relation to man. It is not merely a description of the Earth, rather it accounts for the history of man’s relationship with it, of man’s movements on its surface, and his transformative impact on the world. From this perspective, Friedrich Ratzel was extraordinarily innovative respect to other nineteenth century scholars. That said, however, his revolutionary approach actually relied on an ancient foundation. To understand the basis of Ratzel’s anthropogeographical project it is vital to return to (...) a Greek concept that, over the centuries, has been variously resemantized: the concept of the oecumene. In his understanding of the oecumene, the entire breadth of humanity is conceived in historical and geographical relation to the world around it. Ratzel’s anthropogeography aspires to an all-encompassing understanding of man. In fact, it allows us to reconstruct the coordinates of time and space through which man has developed as a being capable of culture. The Earth, according to Ratzel, transcends its eminently geophysical connotations and becomes more similar to the ancient oecumene. It is, once more, the abode of man; it is that which he knows and recognizes, that to which he gives a name. (shrink)

Resumo Quando pensamos na Grécia, o “lugar dos sonhos” dos alemães, e especialmente na relação de Nietzsche com a Grécia, muitas coisas podem com razão chamar nossa atenção. Grécia pode ser interpretada de diferentes maneiras na obra de Nietzsche. Mas todos podemos talvez concordar que, para Nietzsche, o mundo grego é uma ferramenta de valor crítico insuperável. Eles são testemunhas da diferença que os separa de nós. Eles são uma alternativa cultural inalcançável e inalcançada, para a qual é permitido orientar-nos, (...) mas da qual, frequentemente e mais facilmente, podemos nos separar. Nietzsche serve-se do mundo grego a fim de aprofundar a crise da cega confiança etnocêntrica do homem moderno. Como historiador e filólogo, Nietzsche usa a literatura grega para lutar contra o absolutismo científico do mundo moderno. Sua crítica almeja falsificar as categorias científicas modernas, prosseguindo com um estudo genealógico que deve “transvalorar” as bases da cultura ocidental moderna.When we think of Greece, the “Place of Desire” of the German, and especially of the relation between Nietzsche and Greece, many things could indeed come to our attention. Greece could be interpreted in many different ways in Nietzsche’s work. Although we can all agree that, to Nietzsche, the Greek world is a tool of insurmountable critical value. They are spectators of the difference that separates them from us. They are an unattainable and unattained cultural alternative, which allows us to orient ourselves, although from which, frequently and most easily, we can draw apart from. Nietzsche uses the Greek world in order to deepen the blind ethnocentric confidence crisis of modern man. As a Historian and Philologist, Nietzsche uses Greek literature to fight against scientific absolutism of modern world. His criticism aims to falsify the modern scientific categories, proceeding with a genealogical study, which should “transvaluate” the basis of the modern western society. (shrink)

Alongside his work as a professor of Greek Language and Literature at the University of Basel, Friedrich Nietzsche reflected on the value of classical studies in contemporary nineteenth-century society, starting with a self-analysis of his own classical training and position as a philologist and teacher. Contrary to his well-known aversion to classical philology, a science conceived as being an end in itself, aimed at mere erudite complacency, I highlight Nietzsche’s defence of the system of Classical studies, and of the education (...) of young people through the works of the ancient Greek and Roman period. Such an apology ‘redeems’, in a sense, the discipline, and justifies its role and continued relevance in our present-day society. (shrink)

A word of warning I would offer to those approaching this excellent book by Francesco Ghedini is that it cannot be read alone. For it is the latest, and perhaps not the last, chapter of a long and continuous study of the figure of Plato in Nietzsche’s work that Ghedini began more than a decade ago. In it, Ghedini deals with Nietzsche’s mature works from 1881 to 1887, searching out the images of Plato to be found in them and investigating (...) their significance for Nietzsche’s philosophical trajectory. Ghedini begins, perhaps somewhat abruptly, with The Gay Science, proceeds to an exhaustive analysis of the period of Thus Spoke Zarathustra and Beyond Good and Evil, and ends with a brief consideration of Book V of The ..

Purpose The purpose of this paper is to present a systematic literature review of empirical studies into online platforms for political participation. The objective was to diagnose the relationship between different types of digital participatory platforms, the real possibilities of participation generated by those initiatives and the impact of such participation on the decision-making process of governmental representatives. Design/methodology/approach A systematic literature review was conducted using pre-defined terms, expressions and criteria. A total of 434 articles from 1995 to 2015 were (...) gathered from the Web of Science database. And, 32 studies were selected from those articles for meta-synthesis, and the cases investigated were evaluated according to the e-participation ladder model. Findings The results indicated that online political participation worldwide remains timid both in quantity and quality. We have witnessed the growth of a kind of “rhetorical participation” promoted by policy-makers and the rise of a “participatory despotism”, in which only the privileged partake, while the majority remains silent. Practical implications The solutions found to promote increased participation and ensure its effectiveness ranged from shaping the platform design in accordance with citizens’ capacities and interests to a need for profound political–administrative change, which includes the world’s public agencies adopting a more transparent, inclusive and collaborative approach to decision-making. Originality/value This paper proposes a systematic review, mapping the studies on online platforms for political participation, analysing the questions, methods and conclusions found by the authors and evaluating each case study with a participation ladder.

To date, no definition of life has been unequivocally accepted by the scientific community. In frustration, some authors advocate alternatives to standard definitions. These include using a list of characteristic features, focusing on life’s effects, or categorizing biospheres rather than life itself; treating life as a fuzzy category, a process or a cluster of contingent properties; or advocating a ‘wait-and-see’ approach until other examples of life are created or discovered. But these skeptical, operational, and pluralistic approaches have intensified the debate, (...) rather than settled it. Given the failure of even these approaches, we advocate a new strategy. In this paper, we reverse the usual line of reasoning and argue that the “life problem” arises from thinking incorrectly about the nature of life. Scientists most often conceptualize life as a class or kind, with earthly life as a single instance of it. Instead, we advocate thinking about Earth’s Life as an individual, in the way that species are now thought to be. In this view, Life is a monophyletic clade that originated with a last universal common ancestor, and includes all its descendants. We can continue to use the category ‘life’ pragmatically to refer to similarities between various phenomena and Life. But the relevant similarities are a matter of interest and preference, not a matter of fact. The search for other life in the Universe, then, is merely a search for entities that resemble parts of Life in whatever sense astrobiologists find most appealing. This does not mean that the search for evolved complexity elsewhere in the universe or its creation in the lab are futile endeavors, but that debates over whether they count as ‘life’ are. Ironically, finally abandoning the concept ‘life’ may make our searches for evolved complexity more fruitful. We explain why. (shrink)

Dans les leçons sur la rythmique ancienne de F. Nietzsche, le rythme est objet d’une étude philologique, lié à l’expérience de la parole et du texte, mais aussi et surtout d’une étude anthropologique, parce que son action sera repérée dans les moments originaires de l’organisation religieuse, sociale et civile de l’homme. Le lien entre ces deux approches s’éclaircit quand on comprend que le discours sur le rythme est d’abord un discours sur la forme (en un sens aristotélicien) et sur la (...) norme (la normativité), ou bien sur la convention et sur son rapport avec la nature. Le rythme est une forme qui a une capacité normative, capable d’informer la matière, conçue aussi bien comme poésie et musique ou comme âme, caractère et habitus de l’homme. (shrink)

This paper discusses the varieties of capitalism in transitional societies in Latin America and Central / Eastern Europe. The intended purpose of these transitions from semi-closed import-substituting economies in the first case and state socialist ones in the second was to institutionalize open-market economies. Twenty or thirty years later, there is a variety of types of capitalism in these countries, which I classify into three: open-market, neo-mercantilist, and anemic. The question for sociology is whether these quite different variants represent temporary (...) stages or distortions in the same process of transition or whether, on the contrary, they may institutionalize as discrete forms of peripheral capitalism. Neither standard “legacy” argu­ments nor institutionalist theories offer satisfactory answers to this question. The multiple modernities approach, on the other hand, is more appropriate as a theoretical perspective, but it has not produced yet specific propositions applicable to this question. My paper makes two claims. First, the successful transfer of institutions depends on the congruence between these institutions and the broader institutional framework of the recipient economies, a point not developed by institutionalist theories. I offer a hypothesis in this regard: Two critical nodes of congruence are the regulatory and extractive capacity of the state and the strength of civil society. Second, market capitalism (as liberal democracy as well) is a complex institution, and some of its components “travel” more easily across societies and institutional frameworks, and therefore are easier to institutionalize. This is the source of the hybrid variants. (shrink)

In this paper I respond to Marcus William Hunt’s argument that vegan parents have pro tanto reasons for not raising their children on a vegan diet because such a diet is potentially harmful to children’s physical and social well-being. In my rebuttal, first I show that in practice all vegan diets, with the exception of wacky diets, are beneficial to children’s well-being ; and that all animal-based diets are potentially unhealthful. Second, I show that vegan children are no more socially (...) outcast than any other group. In other words, veganism does not harm the lives of children. Having considered several studies, I show that the moral reasons that vegan parents may have for raising their children on a vegan diet significantly outweigh the reasons for raising their children on an animal-based diet. Thus, I conclude that parents have a moral obligation to raise their children on a vegan diet. (shrink)

Bayesian reverse-engineering is a research strategy for developing three-level explanations of behavior and cognition. Starting from a computational-level analysis of behavior and cognition as optimal probabilistic inference, Bayesian reverse-engineers apply numerous tweaks and heuristics to formulate testable hypotheses at the algorithmic and implementational levels. In so doing, they exploit recent technological advances in Bayesian artificial intelligence, machine learning, and statistics, but also consider established principles from cognitive psychology and neuroscience. Although these tweaks and heuristics are highly pragmatic in character and (...) are often deployed unsystematically, Bayesian reverse-engineering avoids several important worries that have been raised about the explanatory credentials of Bayesian cognitive science: the worry that the lower levels of analysis are being ignored altogether; the challenge that the mathematical models being developed are unfalsifiable; and the charge that the terms ‘optimal’ and ‘rational’ have lost their customary normative force. But while Bayesian reverse-engineering is therefore a viable and productive research strategy, it is also no fool-proof recipe for explanatory success. (shrink)

The philosophical conception of mechanistic explanation is grounded on a limited number of canonical examples. These examples provide an overly narrow view of contemporary scientific practice, because they do not reflect the extent to which the heuristic strategies and descriptive practices that contribute to mechanistic explanation have evolved beyond the well-known methods of decomposition, localization, and pictorial representation. Recent examples from evolutionary robotics and network approaches to biology and neuroscience demonstrate the increasingly important role played by computer simulations and mathematical (...) representations in the epistemic practices of mechanism discovery and mechanism description. These examples also indicate that the scope of mechanistic explanation must be re-examined: With new and increasingly powerful methods of discovery and description comes the possibility of describing mechanisms far more complex than traditionally assumed.

History and memory rank as central themes in the philosophy of Friedrich Nietzsche. As one of the last philosophers of the 19th century, Nietzsche naturally belongs to the so-called ‘historical century’. The contentious exchange with the past and with antiquity – as much as the mechanisms, the dangers, and the lessons of memory and tradition – are continually examined and stand in close relationship with Nietzsche’s vision of life and his project of human development. As Jacob Burckhardt once wrote of (...) the cultural critique to his Basel colleague: "Fundamentally, you are always teaching history". Following Burckhardt’s judgment, the contributors focus on the analysis of core questions in the philosophies of history and memory, and their respective convergence in the thought of Nietzsche. The epistemological relevance of these central concepts will be thematized alongside those concerning tradition, and education. The discussion of these rich themes unifies a broad spectrum of questions, ranging from cultural memory to contemporary philosophy of mind. The contributions are revised versions of selected papers presented at the 2018 conference of the annual meeting of the Nietzsche Society in Naumburg. (shrink)

In a context of pervasive digitalization of the social world, both before and during the COVID-19 pandemic, the field of education has undergone major changes with the development of digital practices and settings. However, the physical presence of the subjects and the body remain something primordial and irreplaceable in traditional educational processes. Thus, it is often assumed that virtuality is opposed to the corporeal reality of the subjects involved in teaching, learning and studying. In this paper we aim to critically (...) challenge this assumption by addressing the phenomenon of virtuality in a more original sense: as a fundamental dimension of corporeality itself. Drawing on Merleau-Ponty’s phenomenological insights, we argue that the experience of the virtual is inherently embodied and fully real. We understand corporeality and virtuality as entangled and multidimensional phenomena. At the same time, this leads us to rethink the digital as only one possible medium in which virtuality can appear as inherent to embodied experience. We develop our phenomenological approach in three instances. First, we question and bracket two common assumptions about corporeality. From our critical perspective, assumptions about a disembodied digitality and a devirtualized corporeality represent extremes within which educational discourses currently move. Second, we address the inherent virtuality of embodied experience. We outline the heuristic concept of the virtual body to describe corporeality and virtuality as entangled and multidimensional phenomena that encompass extension, intercorporeality and intermediality. Finally, we make some remarks on the relationships of corporeality and virtuality considering the challenges of digital education. (shrink)

This chapter subsumes David Marr’s levels of analysis account of explanation in cognitive science under the framework of mechanistic explanation: Answering the questions that define each one of Marr’s three levels is tantamount to describing the component parts and operations of mechanisms, as well as their organization, behavior, and environmental context. By explicating these questions and showing how they are answered in several different cognitive science research programs, this chapter resolves some of the ambiguities that remain in Marr’s account, and (...) shows that many different areas and traditions of cognitive scientific research can be unified under the mechanistic framework.

At least since Kuhn’s Structure, philosophers have studied the influence of social factors in science’s pursuit of truth and knowledge. More recently, formal models and computer simulations have allowed philosophers of science and social epistemologists to dig deeper into the detailed dynamics of scientific research and experimentation, and to develop very seemingly realistic models of the social organization of science. These models purport to be predictive of the optimal allocations of factors, such as diversity of methods used in science, size (...) of groups, and communication channels among researchers. In this paper we argue that the current research faces an empirical challenge. The challenge is to connect simulation models with data. We present possible scenarios about how the challenge may unfold. (shrink)
