Disconnecting a patient from artificial life support, on their request, is often if not always a matter of letting them die, not killing them—and sometimes, permissibly doing so. Stopping a patient’s heart on request, by contrast, is a kind of killing, and rarely if ever a permissible one. The difference seems to be that procedures of the first kind remove an unwanted external support for bodily functioning, rather than intervening in the body itself. What should we say, however, about cases (...) at the boundary—procedures involving items that seem bodily in some respects, but not others? When, for instance, does deactivating an implanted device like a pacemaker count as killing, and when as letting die? Contra existing proposals, I argue that the boundaries of the body for this purpose are not drawn at the boundaries of the self, or (if this is different) the human organism. Nor should we determine when we are killing and when we are letting die by deferring to existing practices for distinguishing ongoing from completed treatment. Rather, I argue that whether something (organic or inorganic) counts as body part for purposes of this distinction depends on the results of a normative analysis of the particular character of our rights in it—particularly, whether and in what way these rights ought to be alienable. I conclude by arguing that there are likely good reasons to recognize distinctively “bodily” rights and restrictions in at least some implantable devices. (shrink)

The body image with respect to physical disability has long been a woefully under-theorized area of scholarship. The literature that does attend to the body image in cases of physical abnormality or functional impairment regularly offer poorly articulated or problematic definitions of the concept, effectively undermining its historic analytic scope and depth. Here, I revisit the epistemic roots of the body image while also engaging the rich contemporary literature from a body studies perspective in order to situate the narratives of (...) amputees about the relationship between dismemberment, prosthetization, phantom limb syndrome, and body image. Stories about living with artificial, fleshy, phantomed, and residual limbs unquestionably reveal a number of peculiarities unique to amputees. However, they also offer a distinctively productive ingress into the analytic utility of a ‘re-visioned’ conceptualization of the body image more broadly speaking. Indeed, the body image can function as a robust investigative tool for exploring the intersubjective, processual, and relational features of embodiment and corporeality. (shrink)

Previous studies have shown that the motion intention recognition for lower limb prosthesis mainly focused on the identification of performed gait. However, the bionic prosthesis needs to know the next movement at the beginning of a new gait, especially in complex operation environments. In this paper, an upcoming locomotion prediction scheme via multilevel classifier fusion was proposed for the complex operation. At first, two motion states, including steady state and transient state, were defined. Steady-state recognition was backtracking of a completed (...) gait, which would be used as prior knowledge of motion prediction. In steady-state recognition, surface electromyographic and inertial sensors were fused to improve recognition accuracy; five typical locomotion modes were recognized by random forest classifier with over 97.8% accuracy. The transient state was defined as an observation period at the initial stage of upcoming movement, in which only the sEMG signal was recorded due to the limitation of sliding window length. LightGBM classifier was validated to outperform other methods in the accuracy and prediction time of transient-state recognition. Finally, a simplified HMM model based on prior knowledge and observation result was constructed to predict upcoming locomotion. The results indicated that the locomotion prediction was over 91% accuracy. The proposed scheme implements the locomotion prediction at the initial stage of each gait and provides critical information for the gait control of lower limb prosthesis. (shrink)

This paper seeks to describe and analyze the traumatic experience through an examination of the sense of agency—the sense of controlling one’s body, and sense of ownership—the sense that it is my body that undergoes experiences. It appears that there exist two levels of traumatic experience: on the first level one loses the sense of agency but retains the sense of ownership, whilst on the second one loses both of these, with symptoms becoming progressively more severe. A comparison of the (...) traumatic experience with various modulations of the senses of agency and ownership, from cases involving prostheses to tools requiring greater or lesser extents of control, suggests that the harsher the traumatic event, the greater the damage is to the sense of ownership, resulting in the increasing sense of the body as a tool rather than an original organism. Likewise, the long-term ramifications become more severe according to the significance of the damage to the sense of ownership. (shrink)

This article argues for a more rigorous distinction between body extensions on the one hand and incorporation of non-bodily objects into the body on the other hand. Real re-embodiment would be a matter of taking things (most often technologies) into the body, i.e. of incorporation of non-bodily items into the body. This, however, is a difficult process often limited by a number of conditions of possibility that are absent in the case of ‘mere’ body extensions. Three categories are discussed: limb (...) extensions/prostheses, perceptual extensions/prostheses and cognitive extensions/prostheses. For each category, a distinction between extensions and incorporations is proposed, and the conditions of possibility for real incorporation are discussed. These conditions of possibility differ in each category, but in general they ask for radical or fundamental alterations not only in the motor and/or sensory or cognitive constitution of a human subject, but also in his or her subjective experience.

There is not one but many ways to picture the world--Australian "x-ray" pictures, cubish collages, Amerindian split-style figures, and pictures in two-point perspective each draw attention to different features of what they represent. Understanding Pictures argues that this diversity is the central fact with which a theory of figurative pictures must reckon. Lopes advances the theory that identifying pictures' subjects is akin to recognizing objects whose appearances have changed over time. He develops a schema for categorizing the different ways pictures (...) represent--the different kinds of meaning they have--and argues that that depiction's epistemic value lies in its representational diversity. He also offers a novel account of the phenomenology of pictorial experience, comparing pictures to visual prostheses like mirrors and binoculars. (shrink)

The nature of representation is a central topic in philosophy. This is the first book to connect problems with understanding representational artifacts, like pictures, diagrams, and inscriptions, to the philosophies of science, mind, and art. Can images be a source of knowledge? Are images merely conventional signs, like words? What is the relationship between the observer and the observed? In this clear and stimulating introduction to the problem John V. Kulvicki explores these questions and more. He discusses: the nature of (...) pictorial experience and "seeing in" recognition, resemblance, pretense, and structural theories of depiction images as aids to scientific discovery and understanding mental imagery and the nature of perceptual content photographs as visual prostheses. In so doing he assesses central problems in the philosophy of images, such as how objects we make come to represent other things, and how we distinguish kinds of representation - pictures, diagrams, graphs - from one another. Essential reading for students and professional philosophers alike, the book also contains chapter summaries, annotated further reading, and a glossary. (shrink)

People with cognitive impairments often have difficulties formulating, understanding, or articulating decisions that others judge reasonable. The frequent response shifts decision-making authority to substitutes through advance directives of the person or guardianship orders from a court. The Convention on the Rights of People with Disabilities defends supported decision-making as an alternative to such forms of supplanted decision-making. But supported decision-making raises both metaphysical questions—what is required for a decision to be the person’s own?—and epistemological questions: how do we know what (...) persons judge to be their good, when they have difficulty conceptualizing and articulating? It raises practical questions, too, such as protection against risks of exploitation. This article uses a non-discrimination account of legal personhood drawn from the CRPD to explore how common features of decisions employed by people without cognitive disabilities are important in supported decision-making too. These features include prostheses, guardrails, relationships, and social contexts. (shrink)

What makes something a part of my body, for moral purposes? Is the body defined naturalistically: by biological relations, or psychological relations, or some combination of the two? This paper approaches this question by considering a borderline case: the status of prostheses. I argue that extant accounts of the body fail to capture prostheses as genuine body parts. Nor, however, do they provide plausible grounds for excluding prostheses, without excluding some paradigm organic parts in the process. I conclude by suggesting (...) that embodiment is moralized all the way down: to be a body part is to be the sort of thing that ought to be protected, in a certain way, by social practices. (shrink)

Technological advances are making devices that functionally replace body parts—artificial organs and limbs—more widely used, and more capable of providing patients with lives that are close to “normal.” Some of the ethical issues this is likely to raise relate to how such prostheses are conceptualized. Prostheses are ambiguous between being inanimate objects and sharing in the status of human bodies—which already have an ambiguous status, as both objects and subjects. At the same time, the possibility of replacing body parts with (...) artificial objects puts pressure on the normative status typically accorded to human bodies, seemingly confirming that body parts are replaceable objects. The paper argues that bodies’ normative status relies on the relation of a body to a person and shows that persons could have similar relations to prostheses. This suggests that in approaching ethical issues surrounding prostheses, it is appropriate to regard them as more like body parts than like objects. (shrink)

In this article I discuss the prosthetic phenomenon during the First World War and Weimar Germany. As opposed to contemporary trends, with their inflationary use of the ‘prosthesis’, sometimes even hypothesizing ‘prostheticization’ as a paradigm, I seek to return the debate about the prosthesis to its historical concreteness. I describe the phenomenology of the prosthesis in three senses: first, in the statistical sense, in the form of a dramatic growth in the number of prostheses; second, in the visual sense, in (...) the form of a dramatic growth in the visibility of the prosthesis. Basing myself on the Heideggerian perception of the ‘phenomenon’, I seek to reveal an additional, third, aspect of the phenomenology of the prosthesis. It is my contention, against the background of the major catastrophe of the First World War and the frequent crises that afflicted Weimar Germany, but also in the light of additional contexts — technological, economic, cultural — that the prosthesis was increasingly perceived as a phenomenon, i.e. as something which appeared in a wide range of ways — as prosthesis, as tool (hammer, writing instrument), as an organic limb (hand, leg), and even as a paradigm (man as ‘prosthetic God’, man as ‘Dasein’).

Donna Haraway's enduring question—“Why should our bodies end at the skin?” —is ever more relevant in the postmodern era, where issues of bodies, boundaries, and technologies increasingly challenge not only the normative performance of the human subject, but also the very understanding of what counts as human. Critical Disability Studies has taken up the problematic of technology, particularly in relation to the deployment of prostheses by people with disabilities. Yet rehabilitation to normative practice or appearance is no longer the point; (...) instead, the lived experience of disability generates its own specific possibilities that both limit and extend the performativity of the embodied self. I look at what is at stake in the challenge to the Western logos that comes specifically from the capacities of the disabled body, understood not as a less than perfect form of the normative, but as figuring difference in a nonbinary sense. Feminist theory has long contested the isomorphism of the logos, but I go beyond simply setting out the grounds for revaluing multiple variant forms. The feminist turn to Jacques Derrida and Gilles Deleuze opens up the problematic to a celebratory positioning of difference and transcorporeality as the very conditions of life. (shrink)

Neural engineers and clinicians are starting to translate advances in electrodes, neural computation, and signal processing into clinically useful devices to allow control of wheelchairs, spellers, prostheses, and other devices. In the process, large amounts of brain data are being generated from participants, including intracortical, subdural and extracranial sources. Brain data is a vital resource for BCI research but there are concerns about whether the collection and use of this data generates risk to privacy. Further, the nature of BCI research (...) involves understanding and making inferences about device users’ mental states, thoughts, and intentions. This, too, raises privacy concerns by providing otherwise unavailable direct or privileged access to individuals mental lives. And BCI-controlled prostheses may change the way clinical care is provided and the type of physical access caregivers have to patients. This, too, has important privacy implications. I In this chapter we examine several of these privacy concerns in light of prominent views of the nature and value of privacy. We argue that increased scrutiny needs to be paid to privacy concerns arising from Big Data and decoding of mental states, but that BCI research may also provide opportunity for individuals to enhance their privacy.

In this article we defend the inferential view of scientific models and idealisation. Models are seen as “inferential prostheses” (instruments for surrogative reasoning) construed by means of an idealisation-concretisation process, which we essentially understand as a kind of counterfactual deformation procedure (also analysed in inferential terms). The value of scientific representation is understood in terms not only of the success of the inferential outcomes arrived at with its help, but also of the heuristic power of representation and their capacity to (...) correct and improve our models. This provides us with an argument against Sugden’s account of credible models: the likelihood or realisticness (their “credibility”) is not always a good measure of their acceptability. As opposed to “credibility” we propose the notion of “enlightening”, which is the capacity of giving us understanding in the sense of an inferential ability. (shrink)

In the last forty years, significant developments in neuroscience, psychology, and robotic technology have been cause for major trend changes in the philosophy of mind. One such shift has been the reallocation of focus from entirely brain-centered theories of mind to more embodied, embedded, and even extended answers to the questions, what are cognitive processes and where do we find such phenomena? Given that hypotheses such as Clark and Chalmers‘ (1998) Extended Mind or Hutto‘s (2006) Radical Enactivism, systematically undermine the (...) organism-bound, internal, and static pictures of minds and allow instead for the distribution of cognitive processes among brains, bodies, and worlds, a worry that arises is that the very subject of cognitive science, the ‗cognizer‘ will be hopelessly opaque, its mind leaking out into the world all over the place, thereby making it impossible to rein in and properly study. A seemingly unrelated and yet parallel trend has also taken place in feminist theorizing about the body over the last forty years. Whereas feminism of the 1970s and early 1980s tended to view ‗the body‘ as the site and matter of biological sex, while gender was a more fluid and socially constituted mode of existence, more recent feminist theory has questioned the givenness of bodies themselves. In other words, rather than seeing gender categories as manifestations of the already given sexed body, thinkers such as Butler (2000) and Lorber (1992) argue that the very notion of a body is often a product of scientific inquiry, which is itself a product of the power structures aiming to maintain a rigid binary between feminine and masculine gender roles. If the world at large plays such a constitutive role in determining who we are, then this implies that the tools we use, the language we speak, and the power relationships in which we are enmeshed are components of what it means to be embodied in any genuine sense. For thinkers like Haraway (1988) the image of the cyborg is most fitting for this new understanding of embodied subjects, as the cyborg is a coupling of machine and human. Gender and even biological sex will always be a technologically hybridized ‗monster‘ consisting of matter, machine, and mind. The overall aim of my project is thus to bring the two concurrent developments in theorizing about embodied subjects into discourse. As the cyborg features largely in recent feminist thought about embodiment, so too has it been a prominent metaphor in philosophy of mind, ever since Clark (2003) claimed that we ought to think of our ‗selves‘ more appropriately as Natural-Born Cyborgs. I therefore focus on this imagery as I go on to make the argument that this distributed account of cognition as well as of sexual identity is more fruitful for making progress in understanding ‗the human‘ more generally. Likewise, I argue that bringing the discussion of sex and gender into the arena of an otherwise asexual philosophy of mind, will shed light on some important facets of embodiment that have been overlooked but that ought to be addressed if we are to have an adequate account of ‗the proper subject of cognitive science.‘ My chapters include 1) a survey of the discourse between science and philosophy of mind leading to these embodied and extended approaches, 2) a first attempt at defending the extended mind thesis, 3) a discussion of how even the supposed resolution to the objections raised against extended cognition fails to properly take into account just how problematic subjectivity is, regardless of its being defined entirely organismic or not, as organisms themselves are highly malleable and socially constituted, 4) an explanation concerning how the same problematization of embodied subjectivity is ongoing in feminist theory, especially considering the phenomenology of transgendered embodiment, intersex, and technologically mediated bodies, 5) further elaboration on technologically enhanced bodies, exposing what I see as a continuum between bodies modified by ‗hard‘ technologies, such as implants, prostheses or surgeries, and those modified by ‗soft‘ technologies, such as gender norms, the social gaze, and technologically mediated metacognition, and last, 6) an argument for the image of the cyborg to replace ‗organism‘ in cognitive science, along with the corollary argument that cyborgs ought to represent not just embodied minds, but should also be the metaphor in attempting to understand ‗embodiment‘ more generally, which must, at its roots, be underpinned by gender and sexual identity. I argue that the imagery is fitting for the proper study of cognitive subjects as well as sexed and gendered bodies, but moreover, that just as the cyborg suggests a blending and hybridizing of seemingly unrelated elements, so too should the two areas of inquiry, philosophy of mind and feminist theory, pay heed to one another‘s use of this imagery and themselves begin to be more integrative in their approaches.

Despite optimistic reports about the results of amputation for advanced vascular disease, the patient’s assessment of advantages and disadvantages is seldom acknowledged. A detailed social study of 67 amputees has revealed considerable disparity between the patient’s views and those of the medical staff. About a third of the patients are forced to retire from active work by the amputation; about three-quarters report a serious decline in their social activities; only about half are really independent with prostheses in the long term; (...) a quarter report severe and intractable symptoms related to their amputation stumps; only about a quarter feel that the amputation was definitely beneficial; and only about one in five feel that the medical staff have provided adequate support during their hospital stay. Amputees face physical and financial disability, isolation, and discomfort. Every effort must be made to explain the implications of amputation honestly and realistically and to ensure continuing patient assessment and support. (shrink)

This article discusses the foresight of philosopher/mathematician Norbert Wiener who, in the 1940s, founded Information Ethics as a research discipline. Wiener envisioned the coming of an “automatic age” in which information technology would have profound social and ethical impacts upon the world. He predicted, for example, machines that will learn, reason and play games; “automatic factories” that will replace assembly‐line workers and middle managers with computerized devices; workers who will perform their jobs over great distances with the aid of new (...) communication technologies; and people who will gain remarkable powers by adding computerized “prostheses” to their bodies. To analyze the ethical implications of such developments, Wiener presented some principles of justice and employed a powerful practical method of ethical analysis. (shrink)

The paper investigates Maurice Merleau-Ponty’s discussion of body and space and Gilles Deleuze’s reading of Francis Bacon’s work, in order to derive a renegotiated interrelation between habitual body, phenomenal space, preferential plane and constructive line. The resulting system is ap- plied as a filter to understand the sartorial fashion of Rei Kawakubo and Hussein Chalayan and their potential as a spatial prosthesis: the operative third skin. If the evolutionary nature of culture demands a constant change, how does the surface of (...) a third skin, which embodies the generative of stable/ unstable, respond to changes of context? The fleeting, shifting conditions of contemporary culture/ lifestyle rely upon, result in, and reflect one constant, change: change of working conditions, family structures, modes of inhabitation, relation networks, of userprofile and identity, of social and territorial boundaries. We occupy the shift- ing spatial parameters of a transitional supermodern environment. Culture, as enacted or embodied through each of these fields, is regulated by a number of abstract and factual variables that interplay constantly: time, space, movement, surface, individual, and data. Elizabeth Grosz argues that culture is an evolutionary effect: it regenerates itself in order to ensure the survival of the species. Each “prosthetic” expression of culture – language, fashion, architecture, etc. – changes repeatedly. Here change is not an end in itself, but a means. And the most successful prosthesis may not be the one that is able to answer the largest number of challenges, but one which itself undergoes a process of learning, self-modification, and differentiation – in short, a process of evolution. Any prosthesis is by nature an extension of the body. In the case of architecture and fashion the prosthesis addressing change is most often external to the body – a “cultural fur” or a surface phenomenon, that is, a highly profiled supplementary skin. As with all prostheses, their respective life-span depends on their ability to reflect a change in context and value systems. They are adapted or updated, if not, they vanish. Any situation of change is processed as a differentiation between the actual and the virtual of a given context. Grosz identifies distinctions between the actual and virtual, the real and the possible: the possible is a preformed real that has not yet received its final materiality, and thus delineates a range of options of becoming. The real is the blueprint of the possible, negotiated by factual limitations, and it is conjoint with the actual through a process of differentiation and divergence. The virtual comprises alternate variations of the actual, it defines a realm of deviation from the blueprint. In order to be responsive to change, the balance between the actual and virtual thus must be rendered unstable: “The virtual requires the actual to diverge, to differentiate itself, to proceed by way of division and disruption, forging modes of actualisation that will transform this virtual into others unforeseen or uncontained within it.” 4 The integration of the virtual allows a re-ordering of the blueprint, a return to the crossroad of possibilities, unlimiting and processing an alternative real, and establishing a state of continual change. A repeated change – not as a choice between a number of options but as a gradual process – marks the moment of evolution, and requires a dynamic system. Such a dynamic can be rendered as an adaptable, flexible, modular, mobile, or morphing system of change. The key lies with the fluency and ability of adaptation for the proposed differentiation between actual and virtual – thus it is an elastic change that is required. The nature of this elasticity is encoded in a repeated repositioning of the variables: a constant fine-tuning of a maximum number of parameters that engineer, alter and define the blueprint. When looking for a dynamic system that incorporates a transformation of skin or space, we are in search of dynamics through an operative surface, controlled by means of the constructive line. Both operative surface and constructive line are generative methods for the formation and form finding of the second and third skin of sartorial fashion and architecture respectively, as they both produce inhabitable or wearable envelopes with a specific responsiveness. Both professions share communication, coding and signage, form information programs, pattern charts, volume outlines, texture fields, surface operations, and implement electronic or digital extensions. In both, the constructive line shapes the surface twice: before production and in operation. The surface demarcates space, spatial envelope, enclosing garment, field of action. In which way can an operative system of the surface with stable/ unstable conditioning generate a phenomenological or evolutionary change in the reconstruction of body and context? How do time, space, movement, surface, individual and data interact in this framework? What is the impact of surface strategies and constructive line on that system? (shrink)

An action-oriented perspective changes the role of an individual from a passive observer to an actively engaged agent interacting in a closed loop with the world as well as with others. Cognition exists to serve action within a landscape that contains both. This chapter surveys this landscape and addresses the status of the pragmatic turn. Its potential influence on science and the study of cognition are considered (including perception, social cognition, social interaction, sensorimotor entrainment, and language acquisition) and its impact (...) on how neuroscience is studied is also investigated (with the notion that brains do not passively build models, but instead support the guidance of action). A review of its implications in robotics and engineering includes a discussion of the application of enactive control principles to couple action and perception in robotics as well as the conceptualization of system design in a more holistic, less modular manner. Practical applications that can impact the human condition are reviewed (e.g., educational applications, treatment possibilities for developmental and psychopathological disorders, the development of neural prostheses). All of this foreshadows the potential societal implications of the pragmatic turn. The chapter concludes that an action-oriented approach emphasizes a continuum of interaction between technical aspects of cognitive systems and robotics, biology, psychology, the social sciences, and the humanities, where the individual is part of a grounded cultural system.

The phenomenological tradition has had a long interest in embodiment, and bodily experience beyond the confines of the “skinbag” body. Here I respond to Helena De Preester’s analysis of different types of protheses: limb, perceptual, cognitive. In her paper “Technology and the body: the (im)possibilities of re-embodiment”, she wants to make finer distinctions between extensions and incorporations . Today’s hi-tech developments make this refinement necessary and possible. I respond to the three levels or types of prostheses taking note of the (...) increasing difficulty at each level and express certain worries about cognitively framed notions of bodily experience.

The success of the London 2012 Paralympic Games not only revealed new public possibilities for the disabled, but also thrust the debates on the relationship between elite Paralympians and advanced prosthetic technology into the spotlight. One of the Paralympic stars, Oscar Pistorius, in particular became celebrated as ‘the Paralympian cyborg’. Also prominent has been Aimee Mullins, a former Paralympian, who became a globally successful fashion model by seeking to establish a new bodily aesthetic utilizing non-organic body parts. This article examines (...) how the modern discourse of prostheses has shifted from the made-up and camouflaged body to the empowered and exhibited body to create a new cultural sensitivity in terms of body image – prosthetic aesthetics. Prosthetic aesthetics oscillates between two polarized sensitivities: attractiveness/‘coolness’, which derive from the image of a perfect human-machine synthetic body, and from abjection/the uncanny, which is evoked by the actual materiality of the lived body incorporating a lifeless human-made body part.

In recent years, neuroscience has been a particularly prolific discipline stimulating many innovative treatment approaches in medicine. However, when it comes to the brain, new techniques of intervention do not always meet with a positive public response, in spite of promising therapeutic benefits. The reason for this caution clearly is the brain’s special importance as “organ of the mind”. As such it is widely held to be the origin of mankind’s unique position among living beings. Likewise, on the level of (...) the individual human being, the brain is considered the material substrate of those traits that in combination render each person unique. In view of this preeminent significance of the brain, it is understandable that, in general, interventions into the brain are considered a delicate issue and that new techniques of intervention are scrutinised with particular care. However, in doing so it is important not to go to the opposite extreme and shy away from promising new therapeutic approaches for debilitating disorders of the brain. With respect to the new techniques of brain intervention a broad interdisciplinary perspective is required to discern irrational fear from justified concern. Hence, the Europäische Akademie established a project group consisting, on the one hand, of experts from different fields of medicine who have got first-hand experience of applying the techniques at issue and, on the other hand, of philosophers and a legal expert. The task of this team was to review the state of the art with respect to each single technique of intervening in the brain, to indicate future developments, and to address the ethical and legal issues common to all of them. The project’s outcome is the book at hand. (shrink)

Therapeutic strategies capable of inducing and enhancing prosthesis embodiment are a key point for better adaptation to and acceptance of prosthetic limbs. In this study, we developed a training protocol using an EMG-based human-machine interface that was applied in the preprosthetic rehabilitation phase of people with amputation. This is a case series with the objective of evaluating the induction and enhancement of the embodiment of a virtual prosthesis. Six men and a woman with unilateral transfemoral traumatic amputation without previous use (...) of prostheses participated in the study. Participants performed a training protocol with the EMG-based HMI, composed of six sessions held twice a week, each lasting 30 mins. This system consisted of myoelectric control of the movements of a virtual prosthesis immersed in a 3D virtual environment. Additionally, vibrotactile stimuli were provided on the participant’s back corresponding to the movements performed. Embodiment was investigated from the following set of measurements: skin conductance response, crossmodal congruency effect, ability to control the virtual prosthesis, and reports before and after the training. The increase in the skin conductance response in conditions where the virtual prosthesis was threatened, recalibration of the peripersonal space perception identified by the crossmodal congruency effect, ability to control the virtual prosthesis, and participant reports consistently showed the induction and enhancement of virtual prosthesis embodiment. Therefore, this protocol using EMG-based HMI was shown to be a viable option to achieve and enhance the embodiment of a virtual prosthetic limb. (shrink)

A theory can be an explanation of a piece of the world. A theory of law is intended to be an explanation of that phenomenon of social communication which we call Law. But, Raffaele De Giorgi, perhaps the person responsible for the introduction of luhmannian theory in Argentina, (jointly with Torres Nafarrate in Mexico in translating Luhmann’s work to Spanish), asked: What is a theory of society? What is the “Law of society”? And answered: Can we discuss this?, hands managed (...) by hands, nothing different from a prostheses. According to De Giorgi we are sure that the themes that we use as objects or objects that we use as themes, are our construction, we think that we turn around ourselves, while we continue rotating around the vacuum. It is a paradox, or another paradox: ¿Is it possible to get out or get rid of these paradoxes? Logic does not help us. Logic, according to Luhmann, can only see to the fact that some expressions, with unavailable truths, are in contradiction with other expressions, the problem cannot be resolved us- ing logical operations. With the help of Gegenparadoxierungen (against-par- adox), systemic therapy is the alternative where the problem can be toler- ated. And, according to Luhmann, the placement of the paradox should be conducted in a more or less skilled, successful, or useful way to break the logjam.A creative use of paradoxes, especially legal ones, allows us to observe how Luhmann’s theory has impacted existing theories in ArgentinaThemes such as the paradoxality of law, or its being without foundation (and without beginning, the vacuity of their principles and the opacity of its distinctions and operations), filtered theories (like Carlos Cárcova or Ernesto Grün) and jurisprudential practices have started shifting things to what Bielefeld Professor has called “old European”Resumen:Una teoría puede ser una explicación de un sector del mundo. Una teoría del derecho pretende ser una explicación de ese fenómeno de comunicación social que llamamos derecho. Pero, Raffaele De Giorgi, tal vez uno de los máximos responsables de la introducción de la teoría de la luhmanniana en la Argentina (junto a Javier Torres Nafarrate de México, a través de su traducción de las obras de Luhmann al español), pregunta:¿Qué es una teoría de la sociedad? ¿Qué es el “Derecho de la sociedad”? y responde: es que podemos discutir esto?, manos que son manejadas por manos, nada diferente de una prótesis. Y agrega: estamos seguros de que los temas que usamos como objetos o los objetos que utilizamos como temas, son nuestra construcción, pensamos que nos volvemos sobre nosotros mismos, mientras continuamos girando alrededor del vacío.Es una paradoja, u otra paradoja. ¿Es posible salir, deshacerse de estas paradojas? La lógica no nos ayuda. La lógica dice Luhmann, sólo puede ver el hecho de que algunas expresiones, cuya verdad no está disponible, entran en contradicción con otras expresiones, para las cuales vale decir la misma cosa. Usando operaciones lógicas, el problema no puede ser resuelto. Como terapia sistémica la única que podemos ver, con el auxilio de la Gegenparadoxierungen (“contra-paradoja”), es un lugar menos doloroso en el que puede tolerarse el problema. Y recordó que, en cierto sentido, la colocación de la paradoja se realizará con más o menos éxito, esto es: de manera útil para desbloquear la situación.Y es el uso creativo de paradojas, especialmente uno que se hizo por el Derecho, el que nos permite observar cómo su teoría (la de Luhmann) se ha comenzado a reciclar en las teorías existentes en Argentina. Temas como el problema de la paradojalidad del Derecho, de su ser sin fundamentos y sin comienzo, de la vacuidad de sus principios y la opacidad de sus operaciones y distinciones, se filtran teorías (como las de Carlos Cárcova o Ernesto Grün) y prácticas de la jurisprudencia y puede verse que ha comenzado a remover ese tipo de pensamiento que el profesor de Bielefeld había llamado “vétero europeo”.

The category of « postmemory » has been invoked by Marianne Hirsch to refer to a traumatic past which is not directly remembered in first person, but is handed down to later generations and is recalled through the mediation of narratives and images which become “prostheses” for a lack of direct memory. But how is it that these prosthetic recollections do not simply substitute for what lacks but seem to shape the very events they are meant to reproduce ? How (...) come an event continues to haunt the memories of the present, even when no immediate remembrance of it is left ? How to think of an “afterimage” of something that was never seen in the first place? It is only quite recently that the role of prosthetic images has been more widely acknowledged in the construction and creation of memories of collective trauma. The paper will focus on the role of photographic images played in remembrance of the Armenian genocide. It shall be shown how the few pictures that were taken by witnesses of the deportations had an afterlife of their own, being reframed and receiving specific interpretations. In particular, the paper will discuss the case of Armin T. Wegner, a German voluntary serving as Sanitary Officer in the Turkish army who, during his fieldwork in 1915/16 in Anatolia and on the Euphrates in Syria, documented the final stages of deportation, taking pictures of the camps at the desert’s fringes. His photos, which are among the most important visual testimonies of the extermination, only belatedly later made Wegner aware of what he had been witnessing, turning him into a witness après coup and to a defender of the Armenian cause.

In this paper, we will focus on the implications of, and relationships between, the concepts of mediation and media. We will focus in particular on the notion of body and linguistic practice as complex actors of mediation between the world and subjective engagements. In the post-phenomenological traditions, the critical theory of Harmut Rosa, and Citton's media studies, it has been pointed out that body and language represent the very prototypes of the construction of media as sensible, affective and formal environments. (...) Thus, the body and language as mediums obey two criteria that seem typical of any anthropologically located technology: they are prostheses that amplify experience and, at the same time, create specific environments which inaugurate ecological diversification.

A virtually infinite array of new discoveries are bringing increasingly evident transformations to all that we do, how we live, how all of us relate to each other, ourselves and the world. To think about this new time, it is necessary to experience the vertigo of placing our mind at risk. We are immersed in a comparatively new context of existence. A new humanity is being built, and it will thus represent a new society and a unique conception of what (...) a person is. We have established ourselves as the cities we pass through daily, as sets of flows, relations of power and strengths. Like a city, we are also information networks; power fields constantly brought into play, as we connect with spaces in an imbricated and interdependent way. We are a kind of species that, in face of its desire, is capable of putting this very existence at risk; of suicidal artists, kamikazes, who risk themselves and the planet. What is the specificity of this species? What is the possible (psycho)analysis? The aim of this article is to present and articulate the current changes and the absolute artificialism of our species in the transformation of its corporeity that devours and appropriates whatever presents itself, and which produces means and prostheses for the compulsive realization of our fantasies; new realities that increasingly appear on the horizon and affect our daily lives. The mind at risk is the state that enables the craziness of any act of creation. (shrink)

The invention of computer simulations used for practicing surgical maneuvers in a video game-like format has an ancestry in the artificial limbs of history and is reflected, grotesquely, in Edgar Allan Poe’s short story, “The Man That Was Used Up” (1850). The nineteenth century worked to ensure that the incomplete body did indeed retain a sense of self by creating prostheses to mimic corporeal wholeness. Our present-day technology seems intent on doing precisely the opposite, deliberately fragmenting the body and challenging (...) our understanding of the body and the prosthetic. (shrink)

A historical and theoretical investigation of the unexpected ways screen-based media protect and excite viewers' fears and anxieties of the worldIn this brilliant contribution to contemporary media studies, acclaimed theorist Francesco Casetti advances a provocative hypothesis: instead of being prostheses that expand or extend our perceptions, modern screen-based media are in fact apparatuses that shelter and protect us from exposure to the world. Rather than bringing us closer to external reality, dominant forms of visual media function as barriers or enclosures (...) that defend against the apparent threats and dangers that seem increasingly to surround us. Working with an original historical overview that begins with the Phantasmagoria of the late eighteenth century, then the shared interior spaces of the movie theater in the early to mid-twentieth century, and finally the solitary digital milieus of the present, Casetti traces the outlines of the protective "bubbles" that disconnect us from our immediate surroundings. To be provided with a shield of immunity to the hazards and uncertainties of the world while experiencing them at a safe remove might seem a positive development. But, he asks, what if these media, instead of providing invulnerability, ensnare individuals in a suffocating enclosure? What if, in their effort to keep reality under control, they exercise a violence equal to that of the dangers they resist? In a dialectical exercise, and through a vivid range of cultural artifacts, Screening Fears traces the emergence of modern protective media and the way they changed our forms of mediation with the world in which we live.

Brain-Computer interfacing is a highly promising and fast developing field of modern life sciences. Recent advances in neuroscience together with progressing miniaturization in micro systems provide insights in structure and functioning of the human brain and enable connections of technical components to neuronal structures as well. This possibly offers a future therapy for paralysed patients through neuronal motor pros-theses. This paper identifies central ethical aspects which have to be considered in further progressing research in this scientific field and the development (...) of neuronal motor prostheses. (shrink)

The article stems from the acknowledgment of the popularity of The Beatles’ faces within popular music and popular culture altogether. Unlike some contemporary and successive male rockstars, the band focused their aesthetic appeal entirely on the faces, omitting other body parts, and therefore keeping astray from a “sex symbol” status in a conventional, eroticized sense. The article analyses the cultural role of The Beatles’ faces in terms of aesthetic features, face expressions, face performances, and extensions/prostheses. These parameters are applied to (...) the chronological development of the face looks adopted by The Beatles during their activity and to the case study of those album covers featuring face close-ups of the band. Additional notes are presented in the area of face representation within the band’s musical repertoire. (shrink)

This article examines a collection of singular artifacts, originating in the 1960s and 1970s, which I call "cybertrance" devices. These devices are based on the reappropriation of instruments from the academic world in order to place users in modified states of consciousness, far from the ordinary mode of wakefulness. All of these inventions draw on the heritage of American cybernetics, and re-articulate the man-machine concept central to it: passing from neo-mechanistic theory to experimentations with coupling and prostheses, and from rational (...) analysis to countercultural mysticism.If these cybertrance devices literally dismantle the man-machine, using technology to disorder the senses, in no way do they seek to...

Where does my body begin? Where does it end? What is inside my body? What is outside? What is primary? What is secondary? What is natural? What is artificial? Science fiction has long imagined a future fusion of humanity with technology. Today, many of us—especially people with health issues such as autoimmune diseases—have functionally become hybrids connected to other machines and to other bodies. The combination of artificial intelligence with implants, transplants, prostheses, and genetic reprogramming is transforming medical research and (...) treatment, and it is now also transforming what we thought was human nature. Mark C. Taylor identifies this process as “intervolution” and explores how it is weaving together smart things and smart bodies to create new forms of life. Our wired bodies are no longer freestanding individuals, but interconnected nodes in worldwide networks. Recognizing this transformation overturns deeply entrenched distinctions and oppositions between minds and bodies. Intervolution reveals that we are already cyborgs, integral cogs in what will become a superorganism of bodies and things. (shrink)

The Renaissance architect, moral philosopher, cryptographer, mathematician, Papal adviser, painter, city planner and land surveyor Leon Battista Alberti provided the theoretical foundations of modern perspective geometry. Alberti’s work on perspective exerted a powerful influence on painters of the stature of Albrecht Dürer, Leonardo da Vinci and Piero della Francesca. But his Della pittura of 1435–36 contains also a hitherto unrecognized ontology of pictorial projection. We sketch this ontology, and show how it can be generalized to apply to representative devices in (...) general, including maps and spatial and non-spatial databases. (shrink)

After decades of specialization within the sciences, the development and application of implantable microchips and biosensors are now being made possible by a growing convergence among seemingly disparate scientific disciplines including, among others, biology, informatics, chemistry, and engineering. This convergence of diverse scientific disciplines is the basis for the creation of new technologies that will have significant medical potential. As of today, implantable microchips and biosensors are being used as mental prostheses to compensate for a loss of normal function, to (...) remotely monitor patients' vital signs, to control the delivery of medications, and to communicate with geographically distant healthcare professionals and the outside environment.

The brain represents the body in different ways for different purposes. Several concepts and even more numerous labels have historically been proposed to define these representations in operational terms. Recent evidence of embodiment of external objects has added complexity to an already quite intricate picture. In particular, because of their perceptual and motor effects, both rubber hands and tools can be conceived as embodied, that is, represented in the brain as if they were parts of one's own body. But are (...) there any limits to what we can embody? What constraints lay upon embodiment? And are they similar both for motor embodiment and for perceptual embodiment? Here, we consider the implications emerging from the different, and up-to-now relatively separate research domains of tool use and rubber hand illusion for understanding the rules of embodiment. In particular, we compare what the embodiment of tools and prostheses may or may not have in common. We conclude that in both cases, although for different reasons and with different constraints, embodiment is only partial. (shrink)

Human augmentation is discussed in three axes: the technological means, the ability being augmented, and the social systems that will be affected. The technological augmentations considered range from exocortical information and communication systems, to pharmaceuticals, tissue and genetic engineering, and prosthetic limbs and organs, to eventually nanomedical robotics, brain-computer interfaces and cognitive prostheses. These technologies are mapped onto the capabilities which we are in the process of enabling and augmenting, which include extending longevity and physical, sensory and cognitive abilities, and (...) enabling control over emotions, moral behavior, and spiritual experience. The impacts of augmentation on the family, education, economy, politics and religion are considered individually, but their aggregate effects will be non-linear and drive complex adaptations in the living machine that is our co-evolved techno-social civilization.

Stanisław Lem’s short story Are you there Mr. Jones?, first published in 1955, is set in a courtroom. The plaintiff is Cybernetics Company – a provider of prosthetics – and the defendant is Harry Jones, a race-car driver. It turns out that Mr. Jones, after a series of grave accidents, has had his entire body gradually replaced by prostheses. He is now deep in debt to the provider, Cybernetics Company, which consequently has sued him to reclaim their property. We aim (...) to show that this short story illustrates important philosophical questions concerning personal identity and persistence over time, and that Lem in fact anticipates several of the main insights of functionalism, later introduced by Putnam (1967) and today a main contender for a theory of the mind. If the identity of Mr. Jones is constituted solely by his prostheses’ functional role, i.e., their causal relations to input, output and other bodily and mental states, Lem here gives us an early example of causal-theoretical functionalism. This brings us to the next question, implicitly raised by Lem: Is functional identity sufficient for personal identity? Is Mr. Jones the same person as he was before replacing all his body parts? In court, Mr. Jones argues for his continued personhood by appealing to memories from the past. This suggests the view that his persistence as a person depends on some form of psychological continuity, and we will discuss how the case of Mr. Jones relates to views on personal identity.

This paper analyzes the process of perceptual recalibration (PR) in light of two cases of technologically-mediated cognition: sensory substitution and perceptual modification. We hold that PR is a very useful concept - perhaps necessary - for explaining the adaptive capacity that natural perceptive systems display as they respond to functional demands from the environment. We also survey critically related issues, such as the role of learning, training, and nervous system plasticity in the recalibrating process. Attention is given to the interaction (...) between technology and cognition, and the case of epistemic prostheses is presented as an illustration. Finally, we address the following theoretical issues: (1) the dynamic character of spatial perception; (2) the role of functional demands in perception; (3) the nature and interaction of sensory modalities. We aim to show that these issues may be addressed empirically and conceptually - hence, the usefulness of sensory-substitution and perceptual-modification studies in the analysis of perception, technologically-mediated cognition, and cognition in general.

This volume summarizes the ethical, social and cultural contexts of interfacing brains and computers. It is intended for the interdisciplinary community of BCI stakeholders. Insofar, engineers, neuroscientists, psychologists, physicians, care-givers and also users and their relatives are concerned. For about the last twenty years brain-computer-interfaces (BCIs) have been investigated with increasing intensity and have in principle shown their potential to be useful tools in diagnostics, rehabilitation and assistive technology. The central promise of BCI technology is enabling severely impaired people in (...) mobility, grasping, communication, and entertainment. Successful applications are for instance communication devices enabling locked-in patients in staying in contact with their environment, or prostheses enabling paralysed people in reaching and grasping. In addition to this, it serves as an introduction to the whole field of BCI for any interested reader. (shrink)

Computer-mediated interaction poses new challenges for theories and models of social interaction concerned with relationships between humans and tools. This article discusses deaf signers using sign language in computer-mediated space, a case in which a new technological ‘tool’ is integrated into existing practices and conventions, but also requires new innovations. An influential model for studying humans, tool use, and social interaction is Activity Theory. However, in analyzing procedures deaf signers use in learning how to manage communication in computer-mediated space, key (...) notions of Activity Theory, notably the ‘mediation’ properties of tools and the categories of subject and tool, are found to be insufficient. I propose adding to the concept of mediation and characterizing the relationship between subjects and new tools in interaction as one in which tools are ‘prostheses’ which interactants learn to inhabit. Based on looking at people learning to use a new technology, I argue, a key process in activities with new tools is a process where interactants learn how to enhance and constrain, extend and transform properties of the human body.

Se realizó un estudio descriptivo para evaluar la influencia de la rehabilitación protésica en la calidad de vida de los pacientes desdentados totales tratados en las clínicas estomatológicas docentes "Ismael Clark Mascaró" y "La Vigía" en Camagüey, desde septiembre del 2009 a septiembre del 2013. El universo estuvo comprendido por 254 pacientes desdentados totales rehabilitados y una muestra de 43, a través de un muestreo probabilístico aleatorio. Se obtuvo un predominio del grupo de 50-69 años y el sexo femenino. Al (...) determinar los problemas mecánicos se apreció que los flancos sobreextendidos, seguido de las inserciones frénicas sin liberar y la presencia de puntos prematuros de contacto, fueron las principales dificultades encontradas en los pacientes portadores de prótesis totales. La rehabilitación influyó en la calidad de vida de estos pacientes.

The article deals with surdotiflopedagogika, a doctrine of special education for deaf–blind–mute children as it was developed in the USSR in the 1920s and 1930s. In the spirit of social constructivism of the early Stalinist society, surdotiflopedagogika presents itself as a technology for the manufacture of socially useful human beings out of handicapped children with sight and hearing impairments, “half-animals, half-plants”. Surdotiflopedagogika’s institutionalization and rationale as these were evolving under the special patronage of Maxim Gorkij are analysed. Its experimental aspect (...) is also discussed. Exploring and implementing the most advanced ideas in the technology of communication, surdotiflopedagogika sought to compensate for the loss of speech, hearing, and sight by supplying the child with mechanical and human prostheses, including other people (assistants), technical devices, techniques of the body, and multiple communication codes to be translated from one into another. In the case of Soviet deaf-blind education, the Soviet subject appears as a technologically enhanced, collectively shared, and extended body in a permanent process of translation, internal as well as external. Technologies of language and acculturation that are of particular interest. Surdotiflopedagogika’s method as it appears in the theoretical writing of Ivan Afanasjevič Sokoljanskij (1889–1960), the teacher of the legendary deaf-blind author and educator Ol’ga Ivanovna Skorokhodova (1914?–1982) are given particular attention.

The aim of this article is to enrich the concept of technological incorporation, as thematized by Merleau-Pontian phenomenology and post-phenomenology, through a study of the material history of artificial prostheses. We will see in the first section that post-phenomenology, by discussing the plasticity of the corporeal schema, did not recognize the importance of technological transformations; that is, it has given little importance to the inorganic, material correlate through which hybridization is possible. Secondly, we will show how Merleau-Ponty, through a reading (...) of Marx, contributes to phenomenology a naturalistic dialectic between material history and corporeity. This relation appears central to our understanding of the constitutively plastic and performative essence of the corporeal schema. The dialectics that technologies institute, however, do not necessarily lead to an increase in one’s perceptive-agentive capacities. The last section of this article investigates this claim through an analysis of the pathology of phantom limbs, in light of the evolution of prosthetic technologies between the two World Wars.
