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.

This paper provides an overview of the account of fictionality — i.e. the phenomenon of things being true “in” or “according to” fictions — that lies at the heart of Kendall Walton's account of representational art. Walton's central idea is that what it is for a proposition to be fictional is for there to be a prescription to imagine that proposition. As we shall see, however, properly understanding this proposal requires an antecedent grasp of Walton's picture of games of make-believe (...) and the relations that artworks bear to appreciators. Having explicated these connections, we will then examine the extensional accuracy of Walton's account of fictionality and its connections to the wider debate about the interpretation of artworks.

Anthony Everett gives a philosophical defence of the common-sense view that there are no such things as fictional people, places, and things. He argues that our talk and thought about such fictional objects takes place within the scope of a pretense, and that we gain little but lose much by accepting fictional realism.

The term “virtual reality” was first coined by Antonin Artaud to describe a value-adding characteristic of certain types of theatrical performances. The expression has more recently come to refer to a broad range of incipient digital technologies that many current philosophers regard as a serious threat to human autonomy and well-being. Their concerns, which are formulated most succinctly in “brain in a vat”-type thought experiments and in Robert Nozick's famous “experience machine” argument, reflect a fundamental misunderstanding of the way that (...) such technologies would probably have to work. They also considerably underestimate the positive contributions that virtual reality technologies could make to the growth of human knowledge. Here, we examine and critique Nozick's claim that no reasonable person would want to plug into his hypothetical experience machine in light of a broadly enactivist understanding of how future VR technologies might be expected to function. We then sketch out a tentative theory of the phenomenon of truth in fiction, in order to characterize some of the distinct epistemic opportunities that VR technologies promise to provide. (shrink)

The basic question of ontology is “What exists?”. The basic question of metaontology is: are there objective answers to the basic question of ontology? Here ontological realists say yes, and ontological anti-realists say no. (Compare: The basic question of ethics is “What is right?”. The basic question of metaethics is: are there objective answers to the basic question of ethics? Here moral realists say yes, and moral anti-realists say no.) For example, the ontologist may ask: Do numbers exist? The Platonist (...) says yes, and the nominalist says no. The metaontologist may ask: is there an objective fact of the matter about whether numbers exist? The ontological realist says yes, and the ontological anti-realist says no. Likewise, the ontologist may ask: Given two distinct entities, when does a mereological sum of those entities exist? The universalist says always, while the nihilist says never. The metaontologist may ask: is there an objective fact of the matter about whether the mereological sum of two distinct entities exists? The ontological realist says yes, and the ontological anti-realist says no. Ontological realism is often traced to Quine (1948), who held that we can determine what exists by seeing which entities are endorsed by our best scientific theory of the world. In recent years, the practice of ontology has often presupposed an ever-stronger ontological realism, and strong versions of ontological realism have received explicit statements by Fine (this volume), Sider (2001; this volume), van Inwagen (1998; this volume), and others.

The purpose of this paper is to clarify what metaontological realism, as discussed in contemporary metaontological literature, amounts to. Although metaontological debates are of relatively long standing, the terms ‘realism’ and ‘anti‐realism’ have only recently come to be regularly applied to metaontological positions. The new usage is not fully stable. This paper aims to: (1) distinguish three key claims associated with the term ‘realism’ in metaontology, and give some initial reasons why it is important to be very clear about the (...) differences between these claims; (2) argue that the three ‘realist’ claims are independent of one other; and (3) argue that the label ‘ontological realism’ is best attached to just one of the three claims, namely the claim that the facts of ontology are objective.

Winner of the 1975 National Book Award, this brilliant and widely acclaimed book is a powerful philosophical challenge to the most widely held political and social positions of our age--liberal, socialist, and conservative.

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)

Wesley Salmon is renowned for his seminal contributions to the philosophy of science. He has powerfully and permanently shaped discussion of such issues as lawlike and probabilistic explanation and the interrelation of explanatory notions to causal notions. This unique volume brings together twenty-six of his essays on subjects related to causality and explanation, written over the period 1971-1995. Six of the essays have never been published before and many others have only appeared in obscure venues. The volume includes a section (...) of accessible introductory pieces, as well as more advanced and technical pieces, and will make essential work in the philosophy of science readily available to both scholars and students.

Mimesis as Make-Believe is important reading for everyone interested in the workings of representational art.

The paper is an extended discussion of what I call the ‘dismissive attitude’ towards metaphysical questions. It has three parts. In the first part, I distinguish three quite different versions of dismissivism. I also argue that there is little reason to think that any of these positions is correct about the discipline of metaphysics as a whole; it is entirely possible that some metaphysical disputes should be dismissed and others should not be. Doing metametaphysics properly requires doing metaphysics first. I (...) then put two particular disputes on the table to be examined in the rest of the paper: the dispute over whether composite objects exist, and the dispute about whether distinct objects can be colocated. In the second part of the paper, I argue against the claim that these disputes are purely verbal disputes. In the third part of the paper, I present a new version of dismissivism, and argue that it is probably the correct view about the two disputes in question. They are not verbal disputes, and the discussion about them to date has not remotely been a waste of time. At this stage, however, our evidence has run out. I argue that neither side of either dispute is simpler than the other, and that the same objections in fact arise against both sides. (For example, the compositional nihilist does not in fact escape the problem of the many, and the one-thinger does not in fact escape the grounding problem.). (shrink)

In this foundational work on the theory of linguistic and mental representation, Stephen Schiffer surveys all the leading theories of meaning and content in the philosophy of language and finds them lacking. He concludes that there can be no correct, positive philosophical theory or linguistic or mental representation and, accordingly advocates the deflationary "no-theory theory of meaning and content." Along the way he takes up functionalism, the nature of propositions and their suitability as contents, the language of thought and other (...) sententialist theories of belief, intention based semantics, and related issues in ontology. Stephen Schiffer is Professor of Philosophy at the City University of New York Graduate Center. A Bradford Book. (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.

"A rich collection. Since it holds a number of introductory pieces along with advanced essays and review articles, the volume will be accessible to a broad audience and will work well in philosophy of science courses....Essential."--Lawrence Sklar, University of Michigan.

Objects and Persons presents an original theory about what kinds of things exist. Trenton Merricks argues that there are no non-living inanimate macrophysical objects -- no statues or rocks or chairs or stars -- because they would have no causal role over and above the causal role of their microphysical parts. Humans do exist: we have non-redundant causal powers. Along the way, Merricks has interesting things to say about mental causation, free will, and various philosophical puzzles. Anyone working in metaphysics (...) will enjoy this lucid and provocative book. (shrink)

Realism concerning a given subject-matter is characterised as a semantic doctrine with metaphysical consequences, namely as the adoption, for the relevant class of statements, of a truth-conditional theory of meaning resting upon the classical two-valued semantics. it is argued that any departure from classical semantics may, though will not necessarily, be seen as in conflict with some variety of realism. a sharp distinction is drawn between the rejection of realism and the acceptance of a reductionist thesis; though intimately related, neither (...) entails the other. realism is to be classified as "naive", "semi-naive" or "sophisticated": the first of these involves an all but unintelligible epistemological component.

The Exclusion Argument, which aims to deny the causal efficacy of irreducible mental properties, is probably the most serious challenge to non-reductive physicalism. Many proposed solutions to the exclusion problem can only reject simplified exclusion arguments, but fail to block a sophisticated version I introduce. In this paper, I attempt to show that we can refute the sophisticated exclusion argument by appeal to a sophisticated understanding of causation, what I call the 'Dual-condition Conception of Causation'. Specifically, I argue that the (...) dual-condition account of causation gives strong support to the so-called 'Autonomy Solution', which contends that even if mental properties are unable to cause (fundamental) physical properties, they can still cause higher-level properties (such as mental, behavioral, and social properties)—if so, human agency would be preserved in the physical world.

Over the last two or three decades, puzzles concerning vagueness, identity, and material constitution have led an increasing number of ontologists to “eliminate” at least some of the objects of folk ontology. In the book here reviewed, Trenton Merricks proposes to eliminate any and all material objects that lack nonredundant causal powers. The objects found lacking include statues, baseballs, planets, and all other inanimate macroscopica, including the masses and conjunctive objects favored by some other eliminativists. The objects found to possess (...) the requisite powers include human persons, who are taken to be human organisms, other conscious organisms, such as dogs and dolphins, and the microscopica of which organisms are composed. Merricks doesn’t assume that there are physical simples. But he does assume that there is at least one level of microscopica, and he uses ‘atoms’ as a convenient term for the microscopica of some unspecified level. As regards organisms that lack consciousness, Merricks is agnostic. (shrink)
