It is shown that a hypothesis about gravity having a virtual cause implies there are two primary reference frames, a reality and a functional virtual reality and an equivalence principle relating the two is postulated. A mathematical expression relating the primary reference frames to the state of reality provides an explanation of particle-wave duality and resolves the controversy about the speed of gravity. A model for motion, time and particle formation is briefly discussed, in which the hypothesis about the virtual cause of gravity and supporting postulates are valid. It is further shown that such model provides solutions to unsolved paradoxes and a unification of consistent but contradictory ancient theories of matter and motion. Finally, a reference is made about the basis for devising experiments and testing the predictions of the model.

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.

In this article I explore ways to argue about punishment of personal representations in virtual reality. I will defend the idea that such punishing might sometimes be morally required. I offer four different lines of argument: one consequentialistic, one appealing to an idea of appropriateness, one using the notion of organic wholes, and one starting from a supposed inability to determine the limits of the extension of the moral agent. I conclude that all four approaches could, in some cases, justify punishing a virtual reality representation; an avatar. As a consequence of my conclusion, I suggest that our institutionalized criminal justice system must be broadened in scope and punitive measures, in order to cover the new and difficult cases arising in virtual reality.

We approach the virtual reality phenomenon by studying its relationship to set theory. This approach offers a characterization of virtual reality in set theoretic terms, and we investigate the case where this is done using the wellfoundedness property. Our hypothesis is that non-wellfounded sets (so-called hypersets) give rise to a different quality of virtual reality than do familiar wellfounded sets. To elaborate this hypothesis, we describe virtual reality through Sommerhoff’s categories of first- and second-order self-awareness; introduced as necessary conditions for consciousness in terms of higher cognitive functions. We then propose a representation of first- and second-order self-awareness through sets, and assume that these sets, which we call events, originally form a collection of wellfounded sets. Strong virtual reality characterizes virtual reality environments which have the limited capacity to create only events associated with wellfounded sets. In contrast, the logically weaker and more general concept of weak virtual reality characterizes collections of virtual reality mediated events altogether forming an entirety larger than any collection of wellfounded sets. By giving reference to Aczel’s hyperset theory we indicate that this definition is not empty because hypersets encompass wellfounded sets already. Moreover, we argue that weak virtual reality could be realized in human history through continued progress in computer technology. Finally, within a more general framework, we use Baltag’s structural theory of sets (STS) to show that within this hyperset theory Sommerhoff’s first- and second-order self-awareness as well as both concepts of virtual reality admit a consistent mathematical representation. To illustrate our ideas, several examples and heuristic arguments are discussed.

In Virtual Worlds, Benjamin Woolley examines the reality of virtual reality.

This article considers the ethical implications of digital virtual reality (DVR) within the context of the place of virtual reality in general in human life and development. This is elaborated through a comparative analysis of the continuity and discontinuity between virtual reality in other mediated forms and DVR. The important role played by virtual reality in human creativity and adaptation sets the context for considering the ethics of DVR in 4 main areas: epistemological questions, questions of distraction and displacement, the content of DVR, and questions of power.

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

This is a follow-up article toPhilip Brey's ``The ethics of representation andaction in Virtual Reality'' (published in thisjournal in January 1999). Brey's call for moreanalysis of ethical issues of virtual reality(VR) is continued by further analyzing issuesin a specialized domain of VR – namelymulti-user environments. Several elements ofBrey's article are critiqued in order to givemore context and a framework for discussion.Issues surrounding representations ofcharacters in multi-user virtual realities aresurveyed in order to focus attention on theimportance of additional discussion andanalysis of specialized aspects of VR.
