This book disentangles the complex meanings of responsibility in nanotechnology development by focusing on its theoretical and empirical dimensions. The notion of responsibility is extremely diversified in the public discourse of nanoscale technologies. Addressed are major disciplinary perspectives working on nanotechnology, e.g. philosophy, sociology, and political science, as well as the major multidisciplinary areas relevant to the innovation process, e.g. technology assessment and ethics. Furthermore, the interplay between such expertises, disciplines, and research programmes in providing a multidisciplinary understanding of responsibility (...) is emphasized. (shrink)

Nick Dyer-Witheford and Greig de Peuter. Games of Empire: Global Capitalism and Video Games . Minneapolis: University of Minnesota Press. 2009. 320pp. pbk. $19.95 ISBN-13: 978-0816666119. In Games of Empire , Nick Dyer-Witheford and Greig de Peuter expand an earlier study of “the video game industry as an aspect of an emerging postindustrial, post-Fordist capitalism” (xxix) to argue that videogames are “exemplary media of Empire” (xxix). Their notion of “Empire” is based on Michael Hardt and Antonio Negri’s Empire (2000), which (...) characterizes the contemporary world order as a decentralized system of global economic, political, and economic power that transcends national boundaries. In the view of the authors, Hardt and Negri’s account sets itself apart from other analyses of international politics by offering a “comprehensive account of conditions of work, forms of subjectivity, and types of struggle in contemporary capital” (xx). Dyer-Witheford and de Peuter thus divide Games of Empire into three sections to reflect each of these aspects of Empire ’s argument, seeing their work as the first account to explore “virtual games within a system of global ownership, privatized property, coercive class relations, military operations, and radical struggle” (xxix). Books in the University of Minnesota Press’s Electronic Mediations series “explore the humanistic and social implications” of new technologies that spark “significant changes in society and culture, politics and economics, thinking and being.” That’s an abstract goal, and one that Games of Empire surely meets. Yet at times it can be difficult to understand exactly which specific intervention this book seeks to make. It is unclear whether the authors of Games of Empire see their work as an indictment of game scholars’ lack of attention to political economy, or whether it’s a work of political theory hoping to show that other disciplines should be paying more attention to the production and play of videogames. Because Dyer-Witheford and de Peuter don’t directly criticize previous political critiques of gaming—such as Edward Castronova’s exploration of the “porous membrane” allowing two-way traffic between virtual economies and those of the real world, or Alexander Galloway’s unraveling of control protocols in algorithmic design, or Ian Bogost’s idea of political procedural rhetoric—they sometimes leave the reader wondering how to situate the book in the broader discourse on games and politics, either separately or together. Thus, Games of Empire might best be seen as an introduction to the writings of Hardt and Negri for game players and designers, rather than as a text for communicating the basic concepts of game studies and design. It is neither a truly new theory of games or digital media, nor is it a new theory of Empire—and that’s not a criticism. It is instead an introduction to Empire through popular culture, as Zizek does for Lacan in Looking Awry . If one were teaching an introductory course on contemporary political theory, this book would offer obvious inroads into Negri and Hardt’s thinking for a number of reasons. Despite its radical ideological bent, the book isn’t off-putting to readers who don’t necessarily share the authors’ politics. It synthesizes complex ideas from difficult thinkers like Marx, Foucault, and Guattari while integrating modifications and critiques of Empire theory itself. And although the book is dense, sometimes feeling longer than it actually is (just over 200 pages), Games of Empire maintains a breezy readability by tightly coupling core concepts of Empire theory to well-known games and widely-publicized conflicts within the videogame industry. The first section of the book focuses on immaterial labor, the accumulation of “cognitive capital,” and the global process of manufacturing videogame consoles. It is significant for the authors that videogames began as hacker experiments within research institutes of the military industrial complex, programmed on stolen time, before becoming a commodity (7). This is the first in a string of examples showing how creative dissidence and conflict fuel the continuing evolution of Empire’s control. Dyer-Witheford and de Peuter explain that the videogame industry now constitutes an international production apparatus dominating both creative work in developed nations and manual labor in developing ones. Because game industries in the United States, Western Europe, and Japan are predominately non-unionized, they serve as an exemplary system for analyzing how global capital exploits contemporary intellectual work—including an excellent analysis of the “EA Spouse” scandal of 2004. On the side of the consumer, the authors argue that rabid “console races” that drive the industry forward from a technological perspective serve to structure gamer identity and combat piracy; later in the book, these machines offer a window into the worlds of Congolese coltan mining and electronic waste (222-224). In the second section, Dyer-Witheford and de Peuter move on to deep case studies of individual games to show how the most popular game genres embed imperial assumptions about conflict, exchange, and urban life. First they argue that military training games such as Full Spectrum Warrior —co-developed by university researchers, industry developers, and military contractors—contribute to the “banalization” of war, a subjective state wherein perpetual preparedness for war is accepted as a part of everyday life (100). Chapter five covers Michel Foucalt’s notion of “biopower,” the extension of capital accumulation to life itself. The authors argue that virtual worlds such as World of Warcraft , which take market capitalism as a given and force players into essentialist roles and racial antagonisms, are organized to maximize control and profit (often on the backs of virtual currency “farmers” in China and southeast Asia). Finally, they criticize the naïve assumption that humor and cynicism in the popular sandbox game franchise Grand Theft Auto offer any remedy to its racialized, violent content. Instead, such games indulge and normalize the fantasy of getting rich at any cost by keeping the realities of contemporary urban life and corporate greed at a safe distance (181). Part three of Games of Empire focuses on “games of multitude,” a preliminary attempt to escape from Empire’s order through alternate modes of videogame development and play. Multitude is defined dialectically, as “the engine and the enemy” of Empire (187). This is the most important, yet also most contradictory section of the text. It lays bare the process by which Empire and its media feed our creative and intellectual development to overabundance. At a certain point, the force of the multitude reaches such a level that it threatens the stability of Empire; however, instead of following Hardt and Negri’s utopian assumptions about the radical potential of the multitude, the authors here follow Paolo Virno’s warning that Empire is “very good at adopting apparently iconoclastic practices and utopian ideas as management techniques and revenue sources” (188). At every turn, advances in player configurative power provide new sources of revenue and advertising angles for the game industry. A disappointing shortcoming of these latter pages is the lack of truly new examples for radical resistance within game development. Instead, it turns out that the radical left seems satisfied with the same mild successes that the left-of-center also has celebrated: artist’s mods, virtual world activism, and critical counterplay within strategy- and wargames. Having been frequently cited by many authors before Dyer-Witheford and de Peuter, this idea of subversion or resistance through play feels tired and unpersuasive. It is unclear if the authors believe it is possible to embrace game design itself as a way of pursuing what they call “exodus” from Empire, or if an all-too-fashionable subversion is the only workable strategy. While the book does explore how the earliest independent game studios were eventually subverted and incorporated into the game industry proper, it doesn’t affirm or critique more recent non-commercial, DIY game development projects such as Klik-of-the-Month Club and Ludum Dare. Dyer-Witheford and de Peuter’s analysis of so-called “tactical games,” including the editorial works of La Molleindustria, leads to an even more ambivalent take on the contemporary design ecology. At the conclusion of his essay on “Countergaming,” Galloway asserts that avant-garde videogame artists “should create new grammars of action […] should create alternative algorithms” (Galloway 125). Yet Dyer-Witheford and de Peuter characterize works such as McDonald’s Video Game and Oiligarchy as didactic, suggesting that the role of radical political games might be “limited to that of agitprop” (199). They are concerned that games like those of Molleindustria rigidly structure the activities of their players in order to prove a point. Yet, despite their repeated assertion that the equation of greater interactivity with democratic digital liberation is flawed, the authors see potential in policy simulators that “allow players to edit or tweak” (202) their parameters in response to what Bogost has called simulation fever , the simultaneous drive toward and fear of simulation (Bogost 108). The possibility of practicing radical design is bucked, and early attempts at critical game development like those of Molleindustria’s seem to be relegated to the status of exceptions that prove the rule for player-centered exodus. Overall, there is one glaring question Games of Empire leaves unanswered: how exactly are videogames the “exemplary media” of Empire, and what are the implications of videogames being exemplary in this way? Presumably Dyer-Witheford and de Peuter want to avoid essentialist claims, so they’re not keen on following Wark’s desire to mark “the game’s difference from [legacy media] as something that speaks to changes in the overall structure of social and technical relations” (Wark 225). It is also unclear how the production apparatuses, labor standards, and subjectivizing processes involved in the creation and use of other any other kind of digital media would fail to justify their equally exemplary status. Even the book’s concluding paragraph holds that virtual games “are one molecular component of this undecidable collective mutation” (Dyer-Witheford and de Peuter 229) of intellect, labor, and daily life. In the end, the authors seem to back away from their focus on games as exemplary to bring their work in line with broader theories of the gradual digitization of the everyday, in line with Galloway and Manovich. Despite these flaws, there is an undeniable elegance to Games of Empire ’s contrasting of gaming’s overwhelmingly imperial content with its multitudinous form . And its ambivalence about the potential of independent or political game development might be seen by scholars of Empire as a strength rather than a weakness, an acceptance that every new expression of multitude offers another opportunity for the expansion of Empire. The book also functions as a strong, all-encompassing call to greater responsibility on the part of mainstream game developers to be more conscious of the ideologies they embed in their work, of the way their intellectual property is used and manipulated by those who employ them, and of the material impact their industry has on the world at large. For players it offers a toolbox of concepts for radical examinations of their own play activities, asking them to be more cognizant of the consequences of their consumption of digital media and the ways in which their virtual lives interface with the real.

This article puts forward some observations about the literary form of Documentalità. The genre to which Documentalità belongs is undoubtedly the philosophical treatise. This is a novelty, because the philosophical treatise is not a popular literary form with contemporary philosophers. But it is a genre that proves to be functional in the project of philosophical reconstruction pursued by Ferraris, and that do not necessarily conflict with the Derridean roots from which Documentality moves.

È noto come il capolavoro di Marcel Proust, À la recherche du temps perdu, sia stato fin dal suo apparire oggetto privilegiato dell’interesse dei filosofi: non sarebbe pertanto fruttuoso, in questa breve recensione, limitarci a porre l’attenzione su tale osservazione. Forse meno noto, e in ogni caso meritevole d’essere posto in evidenza e degno di attenta considerazione, è il fatto che anche negli ultimi anni, i primi del secolo appena nato, si sia assistito, in Italia come in ambito internaz...

In this series of dialogues, Derrida discusses and elaborates on some of the central themes of his work, such as the problems of genesis, justice, authorship and death. Combining autobiographical reflection with philosophical enquiry, Derrida illuminates the ideas that have characterized his thought from its beginning to the present day. If there is one feature that links these contributions, it is the theme of singularity - the uniqueness of the individual, the resistance of existence to philosophy, the temporality of the (...) singular and exceptional moment, and the problem of exemplarity. The second half of this book contains an essay by Maurizio Ferraris, in which he explores the questions of indication, time and the inscription of the transcendental in the empirical. A work of outstanding philosophy and scholarship, the essay is developed in close proximity to Derrida and in dialogue with figures such as Plato, Aristotle, Plotinus, Kant, Hegel and Heidegger. It thereby provides a useful introduction to the philosophy of one of Italy's most prominent philosophers as well as an excellent complement to Derrida's own ideas. A Taste for the Secret consists of material that has never before appeared in English. It will be of interest to second-year undergraduates, graduate students and academics in philosophy, modern languages, literature, literary theory and the humanities generally. (shrink)

Italian political thinker Paolo Virno argues that the category of "multitude" is a far better tool to analyze contemporary issues than the Hobbesian concept of "people." Globalization is forcing us to rethink some of the categories—such as "the people"—that traditionally have been associated with the now eroding state. Italian political thinker Paolo Virno argues that the category of "multitude," elaborated by Spinoza and for the most part left fallow since the seventeenth century, is a far better tool to (...) analyze contemporary issues than the Hobbesian concept of "people," favored by classical political philosophy. Hobbes, who detested the notion of multitude, defined it as shunning political unity, resisting authority, and never entering into lasting agreements. "When they rebel against the state," Hobbes wrote, "the citizens are the multitude against the people." But the multitude isn't just a negative notion, it is a rich concept that allows us to examine anew plural experiences and forms of nonrepresentative democracy. Drawing from philosophy of language, political economics, and ethics, Virno shows that being foreign, "not-feeling-at-home-anywhere," is a condition that forces the multitude to place its trust in the intellect. In conclusion, Virno suggests that the metamorphosis of the social systems in the West during the last twenty years is leading to a paradoxical "Communism of the Capital.". (shrink)

Why is there something rather than nothing? Let’s try to sketch an answer: for a mixture of contingency and necessity. First there was an explosion, which made some highly-concentrated matter unfold and become the world: this was a contingent fact. However, in order for this contingency to emerge, transforming itself into the world, the explosion had to contain not only the ability to expand, but also the ability to record, to keep track. The principle of this emergence is very simple: (...) the past is remembered by memory and repeated by matter. (shrink)

Realitism: the postmodern attack on reality -- Realism: things that have existed since the beginning of the world -- Reconstruction: why criticism starts from reality -- Emancipation: unexamined life has no value.

In this article I defend two theses. The first is that the centrality of recording in the social world is manifested through the production of documents, a phenomenon which has been present since the earliest phases of society and which has undergone an exponential growth through the technological developments of the last decades. The second is that the centrality of documents leads to a view of normativity according to which human beings are primarily passive receptors of rules manifested through documents. (...) We are not intentional producers of values. The latter, as I shall suggest in my conclusion, should be viewed as being ‘socially dependent’ rather than ‘socially constructed’. (shrink)

Introduction to New Realism provides an overview of the movement of contemporary thought named New Realism, by its creator and most celebrated practitioner, Maurizio Ferraris. Sharing significant concerns and features with Speculative Realism and Object Oriented Ontology, New Realism can be said to be one of the most prescient philosophical positions today. Its desire to overcome the postmodern antirealism of Kantian origin, and to reassert the importance of truth and objectivity in the name of a new Enlightenment, has had (...) an enormous resonance both in Europe and in the US. Introduction to New Realism is the first volume dedicated to exposing this continental movement to an anglophone audience.Featuring a foreword by the eminent contemporary philosopher and leading exponent of Speculative Realism, Iain Hamilton Grant, the book begins by tracing the genesis of New Realism, and outlining its central theoretical tenets, before opening onto three distinct sections. The first, 'Negativity', is a critique of the postmodern idea that the world is constructed by our conceptual schemas, all the more so as we have entered the age of digitality and virtuality. The second thesis, 'positivity', proposes the fundamental ontological assertion of New Realism, namely that not only are there parts of reality that are independent of thought, but these parts are also able to act causally over thought and the human world. The third thesis, 'normativity,' applies New Realism to the sphere of the social world. Finally, an afterword written by two young scholars explains in more detail the relationship between New Realism and other forms of contemporary realism. (shrink)

That words express a conceptual content is uncontroversial. This does not entail that their content should break down neatly into a grammatical part, relevant for language and to be analyzed in linguistic terms, and a conceptual part, relevant for cognition and to be analyzed in psychological terms. Various types of empirical evidence are reviewed, showing that the conceptual content of words cannot be isolated from their linguistic properties, because it is affected and shaped by them. The view of words as (...) labels or containers for a non-linguistic conceptual content stems from a naive disregard of the complex and structured nature of lexical knowledge. On the contrary, knowledge of language is shown not just to organize and categorize conceptual content in a way not reducible to non-linguistic cognition, but also to affect its scope, as the range of verbalized concepts is both limited by abstract templates and expanded by productive word formation. This suggests that lexical knowledge is a distinctively linguistic dimension of conceptualization, and that words do not so much label or package concepts, as provide an inner form for conceptual knowledge.

In the Epistle to the Hebrews the terms σκιά and εἰκών are opposed, and most commentators have focused on the latter term, interpreting it as a Platonic allusion. If we consider in more detail the meanings of σκιά and σκιαγραφία, another interpretation appears more likely. Σκιαγραφία means “shading”, “silhouette” or “outline”, and finally “sketch” or – even better – “preliminary drawing”, “underdrawing”or “sinopia”. The last meaning is well attested in the sources at least since the late second or early third (...) century AD and a number of passages in the Fathers alluding to the Epistle support the same conclusion. The term is common in the technical terminology of painters on wooden tablets and was a widely employed topos with different nuances according to different authors. (shrink)

The COVID-19 pandemic is an unprecedented event entailing long-term consequences on population health and welfare. Those who contracted the coronavirus may have suffered from both physical and mental health issues that unfold the need for tailored intervention strategies. Hence, our study aims to investigate the psychological and social consequences of COVID-19 on a sample of 86 participants, encompassing 43 patients recruited from Bari University Hospital, 19 of whom were hospitalized due to the disease. The remaining 43 were individuals not fallen (...) ill with COVID-19 to date. The investigation yielded significant gender differences in post-traumatic stress symptoms, depression, and representation of interpersonal distance, evaluated through the IES-R, the BDI-II, and the IVAS task, respectively. This pattern of results was not replicated in the control group. In general, participants who reported having experienced the most intense post-traumatic symptoms also presented a greater mood deflection and, more specifically, within the clinical group women obtained the highest scores on both scales. Women reported higher IES-R and BDI-II scores compared to men, that could indicate that women who have contracted COVID-19 are more exposed to post-traumatic and depressive symptoms. Our results also showed a significant effect of COVID-19 on IPD with a tendency of disease-experienced individuals to increase their preferred IPD from adults, children, and elderly people. Regarding gender differences in mood and proxemic behavior, a correlation between depressive symptoms and probable PTSD and a further correlation between probable PTSD and greater IPD were found in women from both clinical and control group. Overall, these findings might contribute to a better understanding of gender-based implications of the current pandemic on mental health, also leading to the development of integrated yet personalized intervention strategies.

The influential Italian thinker offers three essays in the political philosophy of language. Multitude between Innovation and Negation by Paolo Virno translated by James Cascaito. The publication of Paolo Virno's first book in English, Grammar of the Multitude, by Semiotext in 2004 was an event within the field of radical political thought and introduced post-'68 currents in Italy to American readers. Multitude between Innovation and Negation, written several years later, offers three essays that take the reader on a (...) journey through the political philosophy of language. “Wit and Innovative Action” explores the ambivalence inevitably arising when the semiotic and the semantic, grammar and experience, rule and regularity, and right and fact intersect. Virno unravels the infinite potential and wonders of everyday linguistic praxis and ambiguity. Wit, he argues, is a public performance, and its modus operandi characterizes human action in a state of emergency; it is a reaction, an articulate response, and a possible solution to a state of crisis. “Mirror Neurons, Linguistic Negation, and Mutual Recognition” examines the relationship of language and intersubjective empathy: without language, would human beings be able to recognize other members of their species? And finally, in “Multitude and Evil,” Virno challenges the distinction between the state of nature and civil society and argues for a political institution that resembles language in its ability to be at once nature and history. Few thinkers take the risks required by innovation. Like a philosophical entrepreneur, Virno is engaged in no less than rewriting the dictionary of political theory, an urgent and ambitious project when language, caught in a permanent state of emergency impossible to sustain, desperately needs to articulate and enact new practices of freedom for the multitude. Paolo Virno is the author of several books, including A Grammar of the Multitude, 2004). (shrink)

Il vero punto, nel confronto tra realisti e postmodernisti, non è ovviamente l’affermazione o negazione dell’esistenza del mondo esterno, ma il costruzionismo: quanto incidono gli schemi concettuali nella costruzione della realtà naturale e sociale? Infatti nessun realista negherebbe che l’IVA dipenda da schemi concettuali . Quello che il realista si chiede è, appunto, fin dove si spinge l’azione degli schemi concettuali, ed è qui che si manifesta il dissidio tra realisti e postmodernisti. Questi ultimi sono molto più generosi nella lista (...) delle parti di realtà che sono socialmente costruite, al punto da affermare, in taluni casi, che noi non abbiamo mai accesso a un mondo "là fuori”, ma solo con ciò che viene costruito dai nostri schemi concettuali.The actual issue at stake, in the confrontation between realists and postmodernists, is not whether you should accept or deny the existence of the external world, but the scope of constructionism: how far conceptual schemes bear on the construction of natural and social reality? Indeed, no realist would deny that the VAT depends on our conceptual schemes, which does not mean that it is purely subjective: you don’t decide whether you have to pay the VAT, it depends on where the purchase takes places. The realist just asks where the sphere of influence of conceptual schemes stops, and here the disagreement with the postmodernists begins. The latter are much more generous in listing the parts of reality that they consider socially constructed, up to maintaining that we do not have any access to the world “out there”, but only to what our conceptual schemes construct.

Scientific literature on particular themes in ontology is extremely abundant, but it is often very hard for freshmen or sophomores to find a red thread between the various proposals. This text is an opinionated introduction, a preliminary text to research in ontology from the so called standard approach to ontological commitment, that is from the particular point of view that connects ontological questions to quantificational questions. It offers a survey of this viewpoint in ontology together with their possible applications through (...) a broad array of examples and open problems and, at the same time, essential references to the classics of philosophy, so as to allow non-specialists to understand the terms and analysis procedures characterizing the discipline. Its result is a wide-ranging overview of the issued tackled by ontology, with a particular focus on the most relevant problems of contemporary debate. (shrink)

Il pensiero politico di Augusto Del Noce si caratterizza per una complessa interpretazione della modernità. Essa non rappresenta per lui il luogo del necessario processo verso la meta finale e perfetta dell’immanenza, che trova nelle religioni secolari del totalitarismo e nel nichilismo scientista delle società opulente la sua più significativa rappresentazione. La modernità come tale va per lui contestata nel suo significato assiologico perché la sua problematizzazione è la condizione filosofica e politica per immaginarne un esito che permetta invece di (...) recuperare il valore della persona umana come luogo dell’apertura alla trascendenza e come prima pietra dell’edificio sociale. Senza questa prospettiva le promesse di emancipazione delle teorie politiche legate ad una idea di progresso ineluttabile ma circoscritto entro visioni materialistiche ed atee sono destinate al fallimento, come è stato tragicamente testimoniato dalla storia. Diversa è stata l’ermeneutica della modernità offerta da Del Noce, che contro la rivoluzione intesa come tentativo di sostituire la religione nell’opera di liberazione dell’uomo dall’alienazione, vede invece nel risorgimento una categoria ancora feconda di possibilità di libertà per l’uomo dell’epoca della secolarizzazione. Di fronte ai dilemmi delle odierne società liberaldemocratiche, la visione personalistica, che fa dell’uomo un essere dotato di un principio di dignità infinito, rimane il retaggio di quelle figure della nostra tradizione ottocentesca che, lungi dall’avere esaurito sue potenzialità, offre per lui ancora delle risorse per la salvezza di ciò rimane di più prezioso dell’umanesimo europeo.

The experience that we got from history of the populisms of the media, of post 9/11 wars, and of the recent economic crisis has led to a harsh denial of two central dogmas of postmodernism: the tenet that reality is socially constructed and infinitely manageable, and the tenet that truth and objectivity are useless notions. Facts, which can’t stand being reduced to interpretations, strike back for their rights. And that confirms the idea that realism has implications not only for a (...) theory of knowledge, but also for ethics and politics. (shrink)

In the last decades, Systems Biology (including cancer research) has been driven by technology, statistical modelling and bioinformatics. In this paper we try to bring biological and philosophical thinking back. We thus aim at making diferent traditions of thought compatible: (a) causality in epidemiology and in philosophical theorizing—notably, the “sufcient-component-cause framework” and the “mark transmission” approach; (b) new acquisitions about disease pathogenesis, e.g. the “branched model” in cancer, and the role of biomarkers in this process; (c) the burgeoning of omics (...) research, with a large number of “signals” and of associations that need to be interpreted. In the paper we summarize frst the current views on carcinogenesis, and then explore the relevance of current philosophical interpretations of “cancer causes”. We try to ofer a unifying framework to incorporate biomarkers and omic data into causal models, referring to a position called “evidential pluralism”. According to this view, causal reasoning is based on both “evidence of diference-making” (e.g. associations) and on “evidence of underlying biological mechanisms”. We conceptualize the way scientists detect and trace signals in terms of information transmission, which is a generalization of the mark transmission theory developed by philosopher Wesley Salmon. Our approach is capable of helping us conceptualize how heterogeneous factors such as micro and macro-biological and psycho-social—are causally linked. This is important not only to understand cancer etiology, but also to design public health policies that target the right causal factors at the macro-level. (shrink)

In this paper we study |$\mathcal{M}\mathcal{V}^{+}$|⁠, i.e. the positive fragment of Łukasiewicz infinite-valued Logic |$\mathcal{M}\mathcal{V}$|⁠. Using mainly algebraic techniques we characterize all the finitary extensions of |$\mathcal{M}\mathcal{V}^{+}$| that are structurally complete and those that are hereditarily structurally complete.
