What psychological and philosophical significance should we attach to recent efforts at computer simulations of human cognitive capacities? In answering this question, I find it useful to distinguish what I will call "strong" AI from "weak" or "cautious" AI. According to weak AI, the principal value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion. (...) But according to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to.

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

Review of T. S. Kuhn's The Essential Tension.

In lieu of an abstract, here is a brief excerpt of the content:Bioshock and the Art of RaptureGrant TavinorI am Andrew Ryan, and I am here to ask you a question. Is a man not entitled to the sweat of his brow? "No!" says the man in Washington, "It belongs to the poor." "No!" says the man in the Vatican, "It belongs to God." "No!" says the man in Moscow, "It belongs to everyone." I rejected these answers; instead, I chose (...) something different. I chose the impossible. I chose Rapture! A city where the artist would not fear the censor; where the scientist would not be bound by petty morality; where the great would not be constrained by the small! And with the sweat of your brow, Rapture can become your city as well.Andrew Ryan, opening BioshockIBioshock is the Masterpiece of recent gaming. Genre-wise the game is a first person-shooter survival-horror game—already a complicated mix of gaming forms—and Bioshock is excellent in these gaming terms: playing the game is a consistently engaging, challenging, and tense experience. The narrative of the game, set in Rapture, a dystopian city beneath the sea, fits perfectly with this interactive gaming form. The premise of Bioshock is a parody of Ayn Rand's objectivist novel Atlas Shrugged. Led by the magnate Andrew Ryan, the industrialists, artists, and scientists have retreated from the world and built Rapture through sheer force of will. But when the player enters the city at the beginning of the game, it is evident that nature is pushing back, and that the sea is slowly but surely retaking Rapture, while its citizens have become corrupted by the arts and sciences the city was built upon: as genetically manipulated "splicers" they now creep through Rapture's darkened halls bemoaning their lost humanity. Andrew Ryan "chose the impossible," [End Page 91] and inevitably his hubris is being repaid by the recalcitrance of human nature and the impermanence of human achievement. Much of the immense fun of Bioshock derives from the irony of an objectivist utopia running amok.The immediate visual impact of Bioshock, depending on its employment of cutting-edge high definition 3D computer graphics, is striking. The aesthetic qualities of the water, in particular, have drawn wide praise. The world of Rapture is also presented through an engaging and excellent style. To depict this decaying world, Bioshock draws on the architectural motifs and cultural themes of 1930s and 1940s America. Portrayals of decaying art deco facades, faded Hollywood socialites, and echoes of Hearst, Hughes, and Citizen Kane, are combined with period music and philosophical and literary references to produce a coherent artistic statement.Two features of Bioshock bear out its unique artfulness as a game. First is the role in the game-world of the Little Sisters: cute little girls that pose a game obstacle with which the player must decide how to deal. In Bioshock, the task of harvesting the game-world resources needed to survive is given a moral dimension in that the resources can be extracted only from the Little Sisters by killing them, and so a key part of the gameplay rests on an emotionally provocative moral choice. The second artful aspect of the game that warrants special attention is a narrative twist partway through the game where it becomes evident that player's principle sympathetic source of information in the game-world is a dissemblance. Bioshock has an interactive twist on an untrustworthy narrator, which clouds and complicates the decisions the player has made in Rapture. Rather than an actor, the player-character is a pawn in someone else's game. At the forefront of both of these aspects of Bioshock are considerations of freewill and morality.To really appreciate the art of Bioshock we need to understand its nature as a game, and moreover, to treat the gaming nature seriously and with sympathy. Bioshock is a videogame, and it is also clearly art; but it is not as if the game is art despite its being a videogame and that the art is a mere gloss or veneer. Rather, Bioshock's nature as a game allows it to be art of a distinctive kind. Treating videogames as a kind... (shrink)

Sorensen presents a general theory of thought experiments: what they are, how they work, what are their virtues and vices. On Sorensen's view, philosophy differs from science in degree, but not in kind. For this reason, he claims, it is possible to understand philosophical thought experiments by concentrating on their resemblance to scientific relatives. Lessons learned about scientific experimentation carry over to thought experiment, and vice versa. Sorensen also assesses the hazards and pseudo-hazards of thought experiments. Although he grants that (...) there are interesting ways in which the method leads us astray, he attacks most scepticism about thought experiments as arbitrary. They should be used, he says, as they generally are used--as part of a diversified portfolio of techniques. All of these devices are individually susceptible to abuse, fallacy, and error. Collectively, however, they provide a network of cross-checks that make for impressive reliability. (shrink)

This paper offers an analytical description of the ethics of game design and its influence in the ethical challenges computer games present. The paper proposes a set of game design suggestions based on the Information Ethics concept of Levels of Abstraction which can be applied to formalise ethical challenges into gameplay mechanics; thus allowing game designers to incorporate ethics as part of the experience of their games. The goal of this paper is twofold: to address some of the reasons why (...) computer games present ethical challenges, and to exploit the informational nature of games to suggest how to develop games with ethics at the core of their gameplay.

Despite their centrality and importance to both science and philosophy, relatively little has been written about thought experiments. This volume brings together a series of extremely interesting studies of the history, mechanics, and applications of this important intellectual resource. A distinguished list of philosophers and scientists consider the role of thought experiments in their various disciplines, and argue that an examination of thought experimentation goes to the heart of both science and philosophy.

Preface: This volume originated in a conference on "The Place of Thought Experiments in Science and Philosophy" which was organized by us and held at the Center for Philosophy of Science at the University of Pittsburgh, April 18-20, 1986. The idea behind this conference was to encourage philosophers and scientists to talk to each other about the role of thought experiments in their various disciplines. These papers were either written for the conference, or were written after it by commentators and (...) other participants.... We hope that this volume will be of use to other philosophers and scientists who are interested in thought experiments, as well as inspire more work in this area.... (shrink)

In this book, Sorensen presents the first general theory of the thought experiment. He analyses a wide variety of thought experiments, ranging from aesthetics to zoology, and explores what thought experiments are, how they work, and what their positive and negative aspects are. Sorensen also sets his theory within an evolutionary framework and integrates recent advances in experimental psychology and the history of science.

: This article seeks to explain how thought experiments work, and also the reasons why they can fail. It is divided into four sections. The first argues that thought experiments in philosophy and science should be treated together. The second examines existing accounts of thought experiments and shows why they are inadequate. The third proposes a better account of thought experiments. According to this account, a thought experimenter manipulates her worldview in accord with the “what if” questions posed by a (...) thought experiment. When all necessary manipulations are carried through, the result is either a consistent model or a contradiction. If a consistent model is achieved, the thought experimenter can conclude that the scenario is possible; if a consistent model cannot be constructed, then the scenario is not possible. The fourth section of the article uses this account to shed light on the circumstances in which thought experiments fail. (shrink)

Are thought experiments nothing but arguments? I argue that it is not possible to make sense of the historical trajectory of certain thought experiments if one takes them to be arguments. Einstein and Bohr disagreed about the outcome of the clock-in-the-box thought experiment, and so they reconstructed it using different arguments. This is to be expected whenever scientists disagree about a thought experiment's outcome. Since any such episode consists of two arguments but just one thought experiment, the thought experiment cannot (...) be the arguments. (shrink)

Despite the emergence of computer games as a dominant cultural industry, we know little or nothing about the ethics of computer games. Considerations of the morality of computer games seldom go beyond intermittent portrayals of them in the mass media as training devices for teenage serial killers. In this first scholarly exploration of the subject, Miguel Sicart addresses broader issues about the ethics of games, the ethics of playing the games, and the ethical responsibilities of game designers. He argues that (...) computer games are ethical objects, that computer game players are ethical agents, and that the ethics of computer games should be seen as a complex network of responsibilities and moral duties. Players should not be considered passive amoral creatures; they reflect, relate, and create with ethical minds. The games they play are ethical systems, with rules that create gameworlds with values at play. Drawing on concepts from philosophy and game studies, Sicart proposes a framework for analyzing the ethics of computer games as both designed objects and player experiences. After presenting his core theoretical arguments and offering a general theory for understanding computer game ethics, Sicart offers case studies examining single-player games, multiplayer games, and online gameworlds from an ethical perspective. He explores issues raised by unethical content in computer games and its possible effect on players and offers a synthesis of design theory and ethics that could be used as both analytical tool and inspiration in the creation of ethical gameplay.

How can _Wii Sports_ teach us about metaphysics? Can playing _World of Warcraft_ lead to greater self-consciousness? How can we learn about aesthetics, ethics and divine attributes from _Zork_, _Grand Theft Auto_, and _Civilization_? A variety of increasingly sophisticated video games are rapidly overtaking books, films, and television as America's most popular form of media entertainment. It is estimated that by 2011 over 30 percent of US households will own a Wii console - about the same percentage that owned a (...) television in 1953. In _Philosophy Through Video Games, _Jon Cogburn and Mark Silcox - philosophers with game industry experience - investigate the aesthetic appeal of video games, their effect on our morals, the insights they give us into our understanding of perceptual knowledge, personal identity, artificial intelligence, and the very meaning of life itself, arguing that video games are popular precisely because they engage with longstanding philosophical problems. Topics covered include: * The Problem of the External World * Dualism and Personal Identity * Artificial and Human Intelligence in the Philosophy of Mind * The Idea of Interactive Art * The Moral Effects of Video Games * Games and God's Goodness Games discussed include: _Madden Football_, _Wii Sports_, _Guitar Hero_, _World of Warcraft_, _Sims Online_, _Second Life_, _Baldur's Gate_, _Knights of the Old Republic_, _Elder Scrolls_, _Zork_, _EverQuest_ _Doom_, _Halo 2_, _Grand Theft Auto_, _Civilization_, _Mortal Kombat_, _Rome: Total War_, _Black and White_, _Aidyn Chronicles_.

Asymmetric conflict is changing the way that we practise and think about war. Torture, rendition, assassination, blackmail, extortion, direct attacks on civilians, and chemical weapons are all finding their way to the battlefield despite longstanding international prohibitions. This book offers a practical guide for policy makers, military officers, students, and others who ask such questions as: do guerillas deserve respect or long jail sentences? Are there grounds to torture guerillas for information or assassinate them on the battlefield? Is there room (...) for nonlethal weapons to subdue militants and safeguard the lives of noncombatants? Who are noncombatants in asymmetric war? What is the status of civilians who shelter and aid guerillas? And, do guerillas have any right to attack civilians, particularly those who aid and shelter members of the stronger army? If one side can expand the scope of civilian vulnerability, then why can't the other? (shrink)

Why computer games can be ethical, how players use their ethical values in gameplay, and the implications for game design.

The most famous challenge to computational cognitive science and artificial intelligence is the philosopher John Searle's "Chinese Room" argument.

Newton's bucket, Einstein's elevator, Schrödinger's cat – these are some of the best-known examples of thought experiments in the natural sciences. But what function do these experiments perform? Are they really experiments at all? Can they help us gain a greater understanding of the natural world? How is it possible that we can learn new things just by thinking? In this revised and updated new edition of his classic text _The Laboratory of the Mind_, James Robert Brown continues to defend (...) apriorism in the physical world. This edition features two new chapters, one on “counter thought experiments” and another on the development of inertial motion. With plenty of illustrations and updated coverage of the debate between Platonic rationalism and classic empiricism, this is a lively and engaging contribution to the field of philosophy of science.

As the contemporary heirs of popular music or cinema, computer games are gradually taking over the mar-kets of entertainment. Much like cinema and music, computer games are taking the spotlight in another front – that which blames them for encouraging unethical behaviors. Apparently, computer games turn their users into blood thirsty zombies with a computer game learnt ability of aiming with deadly precision. The goal of this paper is to pay attention to the ethical nature of computer games, in order (...) to understand better the ways we can evaluate their morality in western cultures providing a framework to understand some of these concerns. This paper poses questions about the ontology of games and their ethical meaning, in an attempt to give ethical theory a word in the analysis of computer games. (shrink)
