Metaphysics of Virtual Reality

The author of this paper discusses the theme of the "simulated body", that is the sense of "being there” in a body that is not one's own, or that does not exist in the way one perceives it. He addresses this issue by comparing Immersive Virtual Reality technology, the phenomenological approach, and Gerald Edelman's theory of Neural Darwinism. Virtual Reality has been used to throw light on some phenomena that cannot be studied experimentally in real life, and the results of (...) its simulations enrich the phenomenological discourse on the lived body. Virtual “Reality” seems to replicate—at least in part—the simulation mechanisms of our mind, thus favoring developments in the field of philosophy of mind. (shrink)

A leading philosopher takes a mind-bending journey through virtual worlds, illuminating the nature of reality and our place within it. Virtual reality is genuine reality; that's the central thesis of Reality+. In a highly original work of "technophilosophy," David J. Chalmers gives a compelling analysis of our technological future. He argues that virtual worlds are not second-class worlds, and that we can live a meaningful life in virtual reality. We may even be in a virtual world already. Along the way, (...) Chalmers conducts a grand tour of big ideas in philosophy and science. He uses virtual reality technology to offer a new perspective on long-established philosophical questions. How do we know that there's an external world? Is there a god? What is the nature of reality? What's the relation between mind and body? How can we lead a good life? All of these questions are illuminated or transformed by Chalmers' mind-bending analysis. Studded with illustrations that bring philosophical issues to life, Reality+ is a major statement that will shape discussion of philosophy, science, and technology for years to come. (shrink)

David Chalmers a récemment soutenu que la réalité virtuelle est réelle, plutôt que fictionnelle. Dans cet article, j’examine les implications ontologiques de ce « réalisme virtuel ». Comme je le suggère, cette position s’associe naturellement à une ontologie algorithmique, qui identifie les objets virtuels à des structures de données comprises de manière fonctionnelle. Je présente ensuite plusieurs objections à cette ontologie algorithmique. Tant que celles-ci ne sont pas réglées, la question de l’identité des mondes et des objets virtuels reste encore (...) en suspens. (shrink)

As David J. Chalmers claims, “virtual reality is a sort of genuine reality, virtual objects are real objects, and what goes on in virtual reality is truly real.” In this paper, I will suggest that the philosophical hypothesis that we might live in a simulation can be considered to be the last and most nihilistic episode in the series of narrations about the true and apparent worlds that Nietzsche sketched in The Twilight of the Idols. I will argue that Nietzsche’s (...) prediction about the obliteration of the apparent world has actually been fulfilled by Chalmers, and I will show why his theory must be considered one of the many fables that humans have been producing in order to organise the world according to their own ends.

The conscious experiences we have during sleep have the potential to improve our empathetic response to those who experience delusions and psychosis by supplying a virtual reality simulation of mental illness. Empathy for those with mental illness is lacking and there has been little improvement in the last decades despite efforts made to increase awareness. Our lack of empathy, in this case, may be due to an inability to accurately mentally simulate what it’s like to have a particular cognitive disorder. (...) Dreaming can help mitigate these deficits by placing the dreamer directly into a realistic virtual simulation and thus increase their capacity for empathy. Increasing empathy would go some way towards reducing the stigma and discrimination faced by people in this group. Recent work suggests that virtual reality can increase empathy towards a variety of marginalised groups, however, this technology is limited in its ability to simulate mental illnesses such as delusions. Dreams, however, are at times virtual reality delusion simulators. They can replicate, to a reasonable degree, delusions and psychosis, and through these experiences, we can learn ‘what it’s like’ to have these conditions. It is essential that we recognise these experiences for what they are, attempt to remember and reflect on them. Instead of disregarding dreams due to their unusualness and bizarreness, we can learn from these experiences and expand our understanding of the human condition and its many forms. (shrink)

Nothing new here. Really. The identification (and correct representation) of space.

Technology is answering our deepest questions about ‘reality.’ This is because Nature continually tokenizes an underlying, omnipresent, continually conserved, circular-linear relationship. Thus, zero and one (modern) is yin and yang (ancient) tying modern and ancient ideas about 'reality' together, and proving tokenization produces a cryptic 'reality.' Explaining science, and the 'search' for answers (perpetually).

What’s presented in our normal waking perceptual visual experiences feels present to us, while what we “see” in pictures and imagine does not. What about dreams? Does what we “see” in a dream feel present? Jennifer Windt has argued for an affirmative answer, for all dreams. But the dreams which flow from the brain’s registration of myoclonic twitches present a challenge to this answer. During these dreams motion-guiding vision is shut off, and, as Mohan Matthen has argued, motion-guiding vision seems (...) to be a key mechanism underlying the feeling of presence. I propose that the feeling of presence in fact involves two components: the feeling of immersion, and the feeling of availability for action. I suggest that only the feeling of availability for action derives from motion-guiding vision, and, hence, hypothesize that body-driven dreams lack this component to the feeling of presence. Finally, the distinction between these two varieties of presence has implications for measures of presence in virtual environments, as these measures can diverge over which of the two varieties they track.

What is the status of a cat in a virtual reality environment? Is it a real object? Or part of a fiction? Virtual realism, as defended by D. J. Chalmers, takes it to be a virtual object that really exists, that has properties and is involved in real events. His preferred specification of virtual realism identifies the cat with a digital object. The project of this paper is to use a comparison between virtual reality environments and scientific computer simulations to (...) critically engage with Chalmers’s position. I first argue that, if it is sound, his virtual realism should also be applied to objects that figure in scientific computer simulations, e.g. to simulated galaxies. This leads to a slippery slope because it implies an unreasonable proliferation of digital objects. A philosophical analysis of scientific computer simulations suggests an alternative picture: The cat and the galaxies are parts of fictional models for which the computer provides model descriptions. This result motivates a deeper analysis of the way in which Chalmers builds up his realism. I argue that he buys realism too cheap. For instance, he does not really specify what virtual objects are supposed to be. As a result, rhetoric aside, his virtual realism isn’t far from a sort of fictionalism. (shrink)

I reply to seven commentaries on “The Virtual and the Real”. In response to Claus Beisbart, Jesper Juul, Peter Ludlow, and Neil McDonnell and Nathan Wildman, I clarify and develop my view that virtual are digital objects, with special attention to the nature of digital objects and data structures. In response to Alyssa Ney and Eric Schwitzgebel, I clarify and defend my spatial functionalism, with special attention to the connections between space and consciousness. In response to Marc Silcox, I clarify (...) and develop my view of the value of virtual worlds, with special attention to the case where we experience these worlds as virtual. (shrink)

Are virtual objects real? I will claim that the question sets us up for the wrong type of conclusion: Chalmers argues that a virtual calculator is a real calculator when it is “organizationally invariant” with its non-virtual counterpart—when it performs calculation. However, virtual reality and games are defined by the fact that they always selectively implement their source material. Even the most detailed virtual car will still have an infinite range of details which are missing. This means that even the (...) most detailed virtual object will still have fictional aspects. Rather than argue that virtual objects are, or aren’t, real, it is preferable to think of overlaps and continuities between the fictional and the real, where even the most painstakingly detailed virtual reality implementation of a non-virtual object is still art: a human process of selection and interpretation. Virtual reality should therefore not be philosophically understood just as a technological implementation on a trajectory to perfection, but as a cultural artifact which derives its value in part from its simplification and difference from its source material. (shrink)

David Chalmers argues that virtual objects exist in the form of data structures that have causal powers. I argue that there is a large class of virtual objects that are social objects and that do not depend upon data structures for their existence. I also argue that data structures are themselves fundamentally social objects. Thus, virtual objects are fundamentally social objects.

Are the objects and events that take place in Virtual Reality genuinely real? Those who answer this question in the affirmative are realists, and those who answer in the negative are irrealists. In this paper we argue against the realist position, as given by Chalmers, and present our own preferred irrealist account of the virtual. We start by disambiguating two potential versions of the realist position—weak and strong— and then go on to argue that neither is plausible. We then introduce (...) a Waltonian variety of ictionalism about the virtual, arguing that this sort of irrealist approach avoids the problems of the realist positions, fits with a unifying theory of representational works, and offers a better account of the phenomenology of engaging in virtual experiences.

This paper draws on the notion of the ‘project,’ as developed in the existential philosophy of Heidegger and Sartre, to articulate an understanding of the existential structure of engagement with virtual worlds. By this philosophical understanding, the individual’s orientation towards a project structures a mechanism of self-determination, meaning that the project is understood essentially as the project to make oneself into a certain kind of being. Drawing on existing research from an existential-philosophical perspective on subjectivity in digital game environments, the (...) notion of a ‘virtual subjectivity’ is proposed to refer to the subjective sense of being-in-the-virtual-world. The paper proposes an understanding of virtual subjectivity as standing in a nested relation to the individual’s subjectivity in the actual world, and argues that it is this relation that allows virtual world experience to gain significance in the light of the individual’s projectual existence. The arguments advanced in this paper pave the way for a comprehensive understanding of the transformative, self-transformative, and therapeutic possibilities and advantages afforded by virtual worlds.

This paper develops a taxonomy of kinds of actions that can be seen in group agency, human–machine interactions, and virtual realities. These kinds of actions are special in that they are not embodied in the ordinary sense. I begin by analysing the notion of embodiment into three separate assumptions that together comprise what I call the Embodiment View. Although this view may find support in paradigmatic cases of agency, I suggest that each of its assumptions can be relaxed. With each (...) assumption that is given up, a different kind of disembodied action becomes available. The taxonomy gives a systematic overview and suggests that disembodied actions have the same theoretical relevance as the actions of any ordinarily embodied human. (shrink)

I argue that virtual reality is a sort of genuine reality. In particular, I argue for virtual digitalism, on which virtual objects are real digital objects, and against virtual fictionalism, on which virtual objects are fictional objects. I also argue that perception in virtual reality need not be illusory, and that life in virtual worlds can have roughly the same sort of value as life in non-virtual worlds.

The Web, in particular real-time interactions in three-dimensional virtual environments (virtual worlds), comes with a set of unique characteristics that leave our traditional frameworks inapplicable. The present article illustrates this by arguing that the notion of “technology relations,” as put forward by Ihde and Verbeek, becomes inapplicable when it comes to the Internet, and this inapplicability shows why these phenomena require new philosophical frameworks. Against this background, and more constructively, the article proposes a fundamental distinction between “intravirtual” and “extravirtual” consequences—a (...) distinction that allows us to understand and conceptualize real-time interactions online more accurately. By relating this distinction to Searle's notion of “condition of satisfaction,” the article also shows its implications for judging real-time, online interactions in virtual worlds as irrational and/or immoral. The ultimate purpose is to illustrate how new philosophical concepts and frameworks can allow us to better account for the unique characteristics of the Internet. (shrink)

What is an avatar -- More than just another pretty face : the avatar effect -- Interview with the virtual cannibal -- Virtual presence -- X-reality, a conclusion.

In this paper, I deal with a striking phenomenon that often occurs when we explore the virtual environment of, for example, a video game. Suppose a friend sees me playing a video game and asks ‘Where are you?’ There are two possible answers to this question. I can either refer to my actual location (‘I am in my room’), but I can also refer to my location in the virtual world (‘I am in a space-ship’). Although my friend is probably (...) after this second reply, the first one is not false. At first sight, this gives rise to a tension. On the one hand both claims – ‘I am in my room’ and ‘I am in a space-ship’ – seem true. But on the other hand they also seem mutually exclusive as bilocation, i.e. being in two places at the same time, is impossible. I am either in London or in Paris, in the bathroom or in the kitchen, in a space-ship or in my room. How can I claim to be in two places at once? In the following, I discuss two ways to dissolve this tension:. (shrink)

The Matrix presents a version of an old philosophical fable: the brain in a vat. A disembodied brain is floating in a vat, inside a scientist’s laboratory. The scientist has arranged that the brain will be stimulated with the same sort of inputs that a normal embodied brain receives. To do this, the brain is connected to a giant computer simulation of a world. The simulation determines which inputs the brain receives. When the brain produces outputs, these are fed back (...) into the simulation. The internal state of the brain is just like that of a normal brain, despite the fact that it lacks a body. From the brain’s point of view, things seem very much as they seem to you and me. (shrink)

Virtual Realism is an art form and a way of living with technology. To explain it, Michael Heim draws on a hypertext of topics, from answering machines to interactive art, from engineering to television programs, from the meaning of UFOs to the Internet. The book begins with the primer 'VR 101'. The issues are discussed, then several chapters illustrate virtual realism with tours through art exhibits and engineering projects. Each chapter suggests a harmony of technology with lifestyle.

On the creation of highly interactive, computer-based multimedia environments in which the user becomes a participant with the computer in a "virtually real" world. Essentially, the volume is a republication of articles published in the summer 1990 issue of Multimedia review, plus an additional previously unpublished article on metaphysics, a directory of companies and individuals working with virtual reality concepts and technology, and a suggested readings list.

The law has neither defined cyberspace nor its values. As a result, the attempt to apply legal rules of "ordinary" space to cyberspace fails to address either the ordinary or the extraordinary features of the new space. This Article proposes that cyberspace be defined as an embodied switched network for moving information traffic, further characterized by degrees of access, navigation, information-activity, augmentation (and trust). Legal conflicts, whether sounding in contract, trademark, copyright, personal jurisdiction, choice of law, or some other basis, (...) occasionally occur in an objective cyberspace whose values can be sufficiently operationalized for legal analysis. If cyberspace were so defined, the law could better respond to new technological uses. (shrink)

This paper provides a critical analysis of virtual environments made in recent leisure and cultural studies discussions, which claim virtual reality to be the technotopia of post-modern society. Such positions describe virtual realities as worlds of in nite freedom, which transcend human subjectivity and where identity becomes no longer burdened by the prejudices of persons. Arguing that cyberspace offers little more than a token gesture towards such liberation, the paper suggests a shift in focus from the power relations that might (...) change or remain because of virtual environments, to an awareness of their implications for human beings. Such technologies as chat rooms, the Internet and cyber-sex, are used to illustrate the fundamental challenge of virtual leisure to the human condition. This human condition is often presumed to represent ‘reality/actuality’ and, as such, is said to be in contrast to virtual environments. However, this paper extends its critique of virtual reality, by questioning such a distinction and arguing that new cyber-virtual reality is no more or no less than a sophistication of virtualness that has always re ected the human, embodied experience. Consequently, it is argued how cyberspace is more profound for its challenge to identity construction than for its emancipatory function. (shrink)

Dreams as Virtual Reality simulations. When David Chalmers wrote “The Virtual and the Real” the argument many focused on the metaphysical and epistemic nature Virtual Reality and how it compares to waking states and dreaming sates. But one interesting segment of the paper is where he defends his thesis by claiming that dreams are not experiences. This is where I take issue and, in my paper, I claim that dreams as much as VR are epistemically similar enough to be called (...) an experience. Exploring my thesis further in how the function of phenomenal and access consciousness play a key role in waking states and dreaming states. Having followed the argument laid out by Chalmers, I first test what would a sufficient answer for my claim look like. Then I chip away at the idea leading to the conclusion that dreams are epistemically rich as waking states. (shrink)
