Fahr’s disease is a rare idiopathic degenerative disease characterized by calcifications in the brain, and has also been associated with balance impairment. However, a detailed analysis of balance in these patients has not been performed. A 69-year-old woman with Fahr’s disease presented with a long-lasting subjective imbalance. Balance was analyzed using both clinical and instrumented tests. The patient’s balance was normal during clinical tests and walking. However, during standing, a striking impairment in vestibular control of balance emerged. The balance behavior (...) displayed mixed parkinsonian and cerebellar features, with a discrepancy between the high severity of the static and the low severity of the dynamic balance impairment. The balance impairment characteristics outlined in this study could help neurologists and physiatrists detect, stage, and treat this rare condition. (shrink)

Falls are frequent in Myotonic Dystrophy type 1, but the pathophysiology of the balance impairment needs further exploration in this disease. The current work aims to provide a richer understanding of DM1 imbalance. Standing balance in 16 patients and 40 controls was tested in two posturographic tests. In the Sensory Organization Test, standstill balance was challenged by combining visual and environmental conditions. In the “react” test, reflexes induced by sudden shifts in the support base were studied. Oscillations of the body (...) centre of mass were measured. In the SOT, COM sway was larger in patients than controls in any condition, including firm support with eyes open. On sway-tuned support, COM oscillations when standing with closed eyes were larger in patients than controls even after taking into account the oscillations with eyes open. In the “react” paradigm, balance reflexes were delayed in patients. Results in both experimental paradigms are consistent with leg muscle weakness. This, however, is not a sufficient explanation. The SOT test highlighted that patients rely on vision more than controls to maintain static balance. Consistently enough, evidence is provided that an impairment of proprioceptive and vestibular systems contributes to falls in DM1. Rehabilitation programs targeted at reweighting sensory systems may be designed to improve safe mobility in DM1. (shrink)

This book explores what it means to exist in virtual worlds. Chiefly drawing on the philosophical traditions of existentialism, it articulates the idea that — by means of our technical equipment and coordinated practices — human beings disclose contexts or worlds in which they can perceive, feel, act, and think. More specifically, this book discusses how virtual worlds allow human beings to take new perspectives on their values and beliefs, and explore previously unexperienced ways of being. Virtual Existentialism will be (...) useful for scholars working in the fields of philosophy, anthropology, media studies, and digital game studies. (shrink)

In this contribution, I defend a robust model of political idealism, making the case for such an approach to both the theory and practice of politics. On this view, not only in framing a political philosophy but also in putting forward policy proposals and institutional designs, we need not think about feasibility as an overriding, make-or-break criterion for evaluating the soundness of that theory or proposal, neither of which loses its point simply because it is deemed to be unlikely to (...) be implemented. Feasibility, in other terms, cannot be taken as the only standard, or even as the main standard, on which basis to assess the practical worth of a political strategy. (shrink)

Self-reflexive videogames are videogames designed to materialize critical and/or satirical perspectives on the ways in which videogames themselves are designed, played, sold, manipulated, experienced, and understood as social objects. This essay focuses on the use of virtual worlds as mediators, and in particular on the use of videogames to guide and encourage reflections on technical, interactive, and thematic conventions in videogame design and development. Structurally, it is composed of two interconnected parts: -/- 1) In the first part of this essay, (...) I will discuss NECESSARY EVIL (Gualeni et al., 2013), an experimental videogame that I designed as a self-reflexive virtual artifact. With the objective of clarifying the philosophical aspirations of self-reflexive videogames – and in order to understand how those aspirations can be practically pursued – I will dissect and examine the design decisions that contributed to the qualities of NECESSARY EVIL as an example of “playable philosophy”. -/- 2) Taking off from the perspectives on self-reflexive videogames offered in the first part of the essay, the second half will focus on virtual worlds as viable mediators of philosophical thought more in general. In this section, I will argue that, both through the practice of game design and through the interactive experiences of virtual worlds, twenty-first century philosophers have the possibility to challenge the often-unquestioned understanding of written discourse as the only context in which philosophical thought can emerge and be developed.

This article explores whether and under which circumstances it is ethically viable to include artificial beings worthy of moral consideration in virtual environments. In particular, the article focuses on virtual environments such as those in digital games and training simulations – interactive and persistent digital artifacts designed to fulfill specific purposes, such as entertainment, education, training, or persuasion. The article introduces the criteria for moral consideration that serve as a framework for this analysis. Adopting this framework, the article tackles the (...) question of whether including artificial intelligences that are entitled to moral consideration in virtual environments constitutes an immoral action on the part of human creators. To address this problem, the article draws on three conceptual lenses from the philosophical branch of ethics: the problem of parenthood and procreation, the question concerning the moral status of animals, and the classical problem of evil. Using a thought experiment, the concluding section proposes a contractualist answer to the question posed in this article. The same section also emphasizes the potential need to reframe our understanding of the design of virtual environments and their future stakeholders. (shrink)

What is it like to be a human being in a simulated world? Will experiencing worlds that are not “actual” change our way of structuring thought? Can virtual worlds open up new possibilities for philosophizing? -/- Virtual Worlds as Philosophical Tools tries to answer those questions from a perspective that is informed and inspired by the philosophy of technology, media theory and the design of digital games. Despite being presented here in a form that is almost exclusively textual, its contents (...) encapsulate the interdisciplinary work of a digital humanist and, as such, are characterized by a degree of practical involvement in the creation and repurposing of digital technology and digitally mediated contents. More specifically, this book emerges from the engagement “in design and development processes that give rise to richer, multidirectional models, genres, iterations of scholarly communication and practice” ( Digital Humanities Manifesto 2.0).

I scrutinize the ideas and works of the Turkish religious leader and author Adnan Oktar/Harun Yahya. I argue for a new definition of Yahya as the representative of what I call theoscientography, proposing to study his work according to such a model rather than in the light of his “Islamic creationism”.

The paper aims at identifying similarities and differences between two different ways of using the word “true”, on the one hand when it is used to refer to a property of what we say or believe, here called “words’ truth”, on the other when it is used to refer to a feature of things in general (as when we say “he is a true friend”), here called “things’ truth”. I will point out how such similarities and differences may be usefully (...) described starting from the feature of truth called “transparency” which is often considered as exclusively pertaining to words’ truth. The upshot of the paper will be that Aquinas was right in considering the two kinds of truth as species of the unique genus “adaequatio rei et intellectus”, but that this conclusion can be reached without any commitment to the ideology (in the Quinean sense) of the correspondence theory of truth.

Problems and questions originally raised by Robert Nozick in his famous thought experiment ‘The Experience Machine’ are frequently invoked in the current discourse concerning virtual worlds. Having conceptualized his Gedankenexperiment in the early seventies, Nozick could not fully anticipate the numerous and profound ways in which the diffusion of computer simulations and video games came to affect the Western world. -/- This article does not articulate whether or not the virtual worlds of video games, digital simulations, and virtual technologies currently (...) actualize (or will actualize) Nozick’s thought experiment. Instead, it proposes a philosophical reflection that focuses on human experiences in the upcoming age of their ‘technical reproducibility’. -/- In pursuing that objective, this article integrates and supplements some of the interrogatives proposed in Robert Nozick’s thought experiment. More specifically, through the lenses of existentialism and philosophy of technology, this article tackles the technical and cultural heritage of virtual reality, and unpacks its potential to function as a tool for self-discovery and self-construction. Ultimately, it provides an interpretation of virtual technologies as novel existential domains. Virtual worlds will not be understood as the contexts where human beings can find completion and satisfaction, but rather as instruments that enable us to embrace ourselves and negotiate with various aspects of our (individual as well as collective) existence in previously-unexperienced guises.

Three types of problems are raised in this commentary: On the linguistic side, we emphasize the importance of an appropriate definition of the different domains of linguistics. This is needed to define the domains (lexicon-syntax-semantics) to which transformational relations apply. We then question the concept of Broca's aphasia as a “functional” syndrome, associated with a specific lesion. Finally, we discuss evidence from functional brain imaging. The breadth and potential impact of such evidence has grown considerably in the last few years, (...) expanding our knowledge of the multiple contributions of the “Broca's region” to phonological, lexical-semantic, and syntactic processing. “Lumping” under diagnostic labels, such as Broca's aphasia, should be replaced by more detailed linguistic and neurological descriptions of the clinical cases.

Este artículo recorre críticamente el análisis del pensamiento heideggeriano sobre el Ser proporcionado por Jean-Luc Marion. Partiendo de Sein und Zeit y llegando a Was ist Metaphysik? se delinea un profundo cambio en el horizonte de sentido en el cual se desarrolla la búsqueda del ser: abandonada la analítica existencial, parece posible una revelación del ser al Dasein sin necesidad de mediaciones ónticas. El artículo intenta sondear las razones y la viabilidad de este pasaje que, según Marion, abre a la (...) pura donación. En el curso de la argumentación son múltiples las confrontaciones con el método fenomenológico de Husserl. (shrink)

En el presente artículo presentamos la filosofía trascendental de Emil Lask como el resultado de una mediación entre la teoría de los dos mundos de Platón y la revolución copernicana de Kant. Aprovechando el descubrimiento de Lotze según el cual los significados no son, sino valen, y ampliando el horizonte de la lógica más allá del ámbito del juicio, Lask elabora un platonismo (o aristotelismo) trascendental que le ubica en un punto medio entre el neokantismo y la fenomenología. Su filosofía (...) entremezcla el trascendentalismo kantiano con el objetivismo típico de la filosofía antigua. El resultado es un trascendentalismo del logos que abarca todos los ámbitos de significado, tanto judicativos, como pre-judicativos. (shrink)

Playing in counterpoint with the general theoretical orientation of the book, this chapter does not focus its attention on the recording and archiving capabilities of the digital medium. Instead, it proposes an understanding of the digital medium that focuses on its disclosing various forms of “doing.” Gualeni’s chapter begins by offering an understanding of “doing in the digital” that methodologically separates “doing as acting” from “doing as making.” After setting its theoretical framework, the chapter discusses an “interactive thought experiment” designed (...) by the author that is analyzed as a digital artifact leveraging both dimensions of “doing in the digital” for philosophical purposes. In extreme synthesis, one could say that this chapter is about several kinds of soups. (shrink)

Philosophical games are games designed to invite players to think philosophically within (and about) their gameworlds. They are interactive fictions allowing players to engage with philosophical themes in ways that often set them apart from non-interactive kinds of speculative fictions (such as philosophical novels or thought experiments). To better understand philosophical games, this entry proposes to distinguish two primary ways in which a philosophical game can approach its themes: dialectically or rhetorically.

If the ancient Stoics conceived passion as a judgment or the consequence of a judgment referring to external reality, it is correct to define their conception of the psyche as ‘monistic’; it is very different if we consider that passion is due to another faculty independent of reason. In this second case, a scenario opens up in which a realistic and ‘reified’ conception of passion emerges. With reference to this, in theLetter113 Seneca discusses the paradoxical thesis of the ancient Stoic (...) scholars according to whom “the soul is an animal”, just as virtues and passions are. Through a series of close logical arguments, he shows the absurdities that can be reached in this way. By comparing this letter with theDe irawe can define the position of Seneca as a type of practical/operational imaginary dualism: the development of an original coherent form of monism. Not to give in to passion (for example to anger or libido) will not be just or not so much a psychological exercise of reason and will, but certainly a physical experience of resistance. (shrink)

A relatively common approach in game studies understands gameworlds as constituting an existential situation for the player. Taking that stance, which is rooted in the European philosophical tradition of Existentialism, in this chapter we investigate the relationships and similarities between our existence within and without gameworlds. To do so, we first provide a review of existing literature in ‘existential ludology’ - work in game studies which considers our engagement with gameworlds from an existential perspective. In the second part of the (...) chapter, we then engage with some of the most notable ideas of the Norwegian philosopher Peter Wessel Zapffe. Zapffe understood human life as inherently meaningless and identified four ways in which human beings typically protect themselves from the existential panic that accompanies the awareness of that meaninglessness: isolation, anchoring, distraction, and sublimation. These four categories are used as the foundation for an examination of gameworlds as technologies for repressing existential panic. (shrink)

‘Simulation Hypotheses’ are imaginative scenarios that are typically employed in philosophy to speculate on how likely it is that we are currently living within a simulated universe as well as on our possibility for ever discerning whether we do in fact inhabit one. These philosophical questions in particular overshadowed other aspects and potential uses of simulation hypotheses, some of which are foregrounded in this article. More specifically, “A Theodicy for Artificial Universes” focuses on the moral implications of simulation hypotheses with (...) the objective of speculatively answering questions concerning computer simulations such as: If we are indeed living in a computer simulation, what might be its purpose? What aspirations and values could be inferentially attributed to its alleged creators? And would living in a simulated universe affect the value and meaning we attribute to our existence? (shrink)

Drawing from narratology and design studies, this article makes use of the notions of the ‘implied designer’ and ‘ludic unreliability’ to understand deceptive game design as a specific sub-set of transgressive game design. More specifically, in this text we present deceptive game design as the deliberate attempt to misguide players’ inferences about the designers’ intentions. Furthermore, we argue that deceptive design should not merely be taken as a set of design choices aimed at misleading players in their efforts to understand (...) the game, but also as decisions devised to give rise to experiential and emotional effects that are in the interest of players. Finally, we propose to introduce a distinction between two varieties of deceptive design approaches based on whether they operate in an overt or a covert fashion in relation to player experience. Our analysis casts light on expressive possibilities that are not customarily part of the dominant paradigm of user-centered design, and can inform game designers in their pursuit of wider and more nuanced creative aspirations.

A common understanding of the role of a game developer includes establishing (or at least partially establishing) what is interactively and perceptually available in (video)game environments: what elements and behaviors those worlds include and allow, and what is – instead – left out of their ‘possibility horizon’. The term ‘possibility horizon’ references the Ancient Greek origin of the term ‘horizon’, ὄρος (oros), which denotes a frontier – a spatial limit. On this etymological foundation, ‘horizon’ is used here to indicate the (...) spatial and operational boundaries that a (video)game environment affords its players. This book chapter discusses a particular feeling that emerge in relation to playful encounters with the ‘possibility horizons’ of videogames. I am referring here to the realization, as a player, that a game environment can be experientially exhausted and is, as such, ultimately banal. In other words, I will examine how our deliberate engagement with the interactive environments of digital games can trigger sensations that are analogous to what Romantic authors referred to as Weltschmerz (‘world-weariness’).

Within dramatherapy and psychodrama, the term ‘de-roling’ indicates a set of activities that assist the subjects of therapy in ‘disrobing’ themselves from their fictional characters. Starting from the psychological needs and the therapeutic goals that ‘de-roling’ techniques address in dramatherapy and psychodrama, this text provides a broader understanding of procedures and exercises that define and ease transitional experiences across cultural practices such as religious rituals and spatial design. After this introductory section, we propose a tentative answer as to why game (...) studies and virtual world research largely ignored processes of ‘roling’ and ‘de-roling’ that separate the lived experience of role-play from our everyday sense of the self. The concluding sections argue that de-roling techniques are likely to become more relevant, both academically and in terms of their practical applications, with the growing diffusion of virtual technologies in social practices. The relationships we can establish with ourselves and with our surroundings in digital virtual worlds are, we argue, only partially comparable with similar occurrences in pre-digital practices of subjectification. We propose a perspective according to which the accessibility and immersive phenomenological richness of virtual reality technologies are likely to exacerbate the potentially dissociative effects of virtual reality applications. This text constitutes an initial step towards framing specific socio-technical concerns and starting a timely conversation that binds together dramatherapy, psychodrama, game studies, and the design of digital virtual worlds.

While agent-based modelling languages naturally implement concurrency, the currently available languages for argumentation do not allow to explicitly model this type of interaction. In this paper we introduce a concurrent language for handling agents arguing and communicating using a shared argumentation space. We also show how to perform high-level operations like persuasion and negotiation through basic belief revision constructs, and present a working implementation of the language and the associated web interface.

Bringing together world-class scholars who have devoted themselves to the study of legal obligation, this book addresses key dimensions of the current debate: providing novel insights and perspectives, as well as critically discussing the leading theories of legal obligation. The notion of legal obligation is widely regarded as fundamental by both legal practitioners and legal theorists. For the language that explicitly refers to obligation is pervasive insofar as paradigmatic legal materials make reference to obligation either directly, by specifying what a (...) subject is obligated to do, or indirectly, by attributing rights, privileges, powers, permissions, and other normative statuses to both single individuals and groups. There is, then, broad agreement that obligation constitutes a central element in legal studies. At the same time, however, there is considerable disagreement among contemporary legal theorists about how legal obligation can or should be elucidated. This book accounts for both the significance of obligation in law and the variety of views of legal obligation championed in legal philosophy today. With contributions from renowned theorists, this book will be invaluable for scholars and students of legal theory, legal philosophy and jurisprudence. (shrink)

Mit diesem Text möchte ich zu der Debatte über den Status und die Legitimität prinzipientreuen Ungehorsams in einer demokratischen Gesellschaft beitragen. Nach der Einführung dieses Begriffs argumentiere ich dafür, dass sich prinzipientreuer Ungehorsam nicht nur als moralische und politische Haltung, sondern auch als rechtliche Verpflichtung darstellen lässt. Im Ergebnis vertrete ich, dass wir nicht nur prinzipientreu gegen das Gesetz verstoßen können, ohne notwendigerweise unsere rechtlichen Verpflichtungen zu verletzen, sondern dass rechtliche Verpflichtungen prinzipientreuen Ungehorsam sogar vorschreiben können. Mit dieser Rahmung des (...) Problems prinzipientreuen Gesetzesbruchs wird die Diskussion um eine neue Position erweitert, nach der wir nicht nur eine moralische Rechtfertigung haben können, das Gesetz zu missachten, sondern auch eine rechtliche Verpflichtung dazu, nämlich eine Verpflichtung, das Gesetz aus prinzipiellen rechtlichen Gründen zu brechen.
