Prior research suggests brokers do not always act in the best interests of clients, although morally obligated to do so. We empirically investigated this issue focusing on trades executed at best execution price, before and after the introduction of electronic limit-order trading, on the London Stock Exchange. As a result of limit-order trading, the proportion of trades executed at the best execution price for the customer significantly increased. We attribute this to a sustained increase in the liquidity of stocks as (...) a result of limit-order trading, regardless of market capitalisation. We discuss the ethical implications of our findings and conclude that market structures that enhance market competitiveness may help reconcile broker and client interests. (shrink)

This study examined the link between employees’ adult attachment orientations and perceptions of line managers’ interpersonal justice behaviors, and the moderating effect of national culture. Participants from countries categorized as low collectivistic and high collectivistic completed an online survey. Attachment anxiety and avoidance were negatively related to interpersonal justice perceptions. Cultural differences did not moderate the effects of avoidance. However, the relationship between attachment anxiety and interpersonal justice was non-significant in the Southern Asia cultural cluster. Our findings indicate the importance (...) of ‘fit’ between cultural relational values and individual attachment orientations in shaping interpersonal justice perceptions, and highlight the need for more non-western organizational justice research.

Through a phenomenological study of horse-human relations, this article explores the ways in which, as embodied beings, we live relationally, rather than as separate human identities. Conceptually this challenges oppositional logic and humanist assumptions, but where poststructuralist treatments of these issues tend to remain abstract, this article is concerned with an embodied demonstration of the ways in which we experience a relational or in-between logic in our everyday lives.

We argue that pedagogic authority relies on love, which is misunderstood if seen as a matter of actions and subjects. Love is based not on finite subjects and objects existing in Euclidean space and linear time, but, rather, on the non-finite ontology, space and time of relations. Loving authority is a matter of calling and vocation, arising from the spontaneous and simultaneous call-and-response of a lively relation. We make this argument through a reading of Buber’s I–You relation and Murdoch’ s (...) account of the responsiveness of ascetic discipline. In presenting this analysis, we draw upon a case study from a research project on Australian teachers and students. (shrink)

One of three distinct approaches to his famous ‘Trust’ argument, this paper written by Garfinkel in 1960, and never before published, proposed a rethinking of rules, games and linguistic classifications in interactional terms consistent with Wittgenstein’s language games. Garfinkel had been working in collaboration with Parsons since 1958 to craft an approach to culture that would replace conceptual classification with the constitutive expectancies of interaction and systems of interaction. The argument challenged the work of cultural anthropologists influenced by (...) zoology and biology, who called themselves ‘ethnoscientists’ and studied culture in terms of linguistic classification systems. Garfinkel had proposed an alternative sociological ‘ethnoscience’ of culture and language that would focus on how culture was made, on how linguistic events are achieved, and on the rules of their making. This ‘Language Games’ approach followed Wittgenstein in seeking what Garfinkel called a literal description of cultural/linguistic events: meaning by ‘literal’, a step-by-step account of the constitutive and preferred rules participants use to create a recognizable event-in-a-language. Made famous three years later in version associated with Schutz, Garfinkel’s Trust argument also appears in a 1962 text (Parsons’ Primer, published in 2019) in a version built on Parsons. (shrink)

This paper forges links between early analytic philosophy and the posits of semiotics. I show that there are some striking and potentially quite important, but perhaps unrecognized, connections between three key concepts in Wittgenstein’s middle and later philosophy, namely, complex, rule-following, and language games. This reveals the existence of a conceptual continuity between Wittgenstein’s “early” and “later” philosophy that can be applied to the analysis of the iterability of representation in computer-generated images. Methodologically, this paper clarifies to at least (...) some degree, the nature, progress and promise of an approach to doing philosophy and semiotics from a modally modest perspective that sees in the intellectual products of humanities, and not in unreflective empiricism, the future of scientific development. This hybrid, non-reductionist approach shows, among other things, that semiotic processes are encoded by specific types of complexes in computer-generated images that display iterability in time and space.

This paper considers what it is about violent video games that leads one reasonably minded person to declare “That is immoral” while another denies it. Three interpretations of video game content are discussed: reductionist, narrow, and broad. It is argued that a broad interpretation is required for a moral objection to be justified. It is further argued that understanding the meaning of moral utterances—like “x is immoral”—is important to an understanding of why there is a lack of moral consensus (...) when it comes to the content of violent video games. Constructive ecumenical expressivism is presented as a means of explaining what it is that we are doing when we make moral pronouncements and why, when it comes to video game content, differing moral attitudes abound. Constructive ecumenical expressivism is also presented as a means of illuminating what would be required for moral consensus to be achieved. (shrink)

Cohen and Meskin 2006 have recently proposed a novel counterfactual account of information. I argue that it is a step down from its intended target, namely Dretske's 1981 theory of information. Thinking of the information carried by signals in terms of counterfactuals leads to falsely diagnosing bona fide instances of information transmission as not being instances of information transmission at all, with major loss of explanatory power.

I argue that by any major definition of art many modern video games should be considered art. Rather than defining art and defending video games based on a single contentious definition, I offer reasons for thinking that video games can be art according to historical, aesthetic, institutional, representational and expressive theories of art. Overall, I argue that while many video games probably should not be considered art, there are good reasons to think that some video (...) class='Hi'>games should be classified as art. I also show that the debates over the artistic status of chess and sports offer some insights into the status of video games. (shrink)

In the mid twentieth century the philosopher Ludwig Wittgenstein famously asserted that games are indefinable; there are no common threads that link them all. "Nonsense," says the sensible Bernard Suits: "playing a game is a voluntary attempt to overcome unnecessary obstacles." The short book Suits wrote demonstrating precisely that is as playful as it is insightful, as stimulating as it is delightful. Suits not only argues that games can be meaningfully defined; he also suggests that playing games (...) is a central part of the ideal of human existence, so games belong at the heart of any vision of Utopia. Originally published in 1978, The Grasshopper is now re-issued with a new introduction by Thomas Hurka and with additional material (much of it previously unpublished) by the author, in which he expands on the ideas put forward in The Grasshopper and answers some questions that have been raised by critics.

Martial-arts practice is not quite anything else: it is like sport, but is not sport; it constantly refers to and as it were cohabits with violence, but is not violent; it is dance-like but not dance. It shares a common athleticism with sports and dance, yet stands apart from both, especially through its paradoxical commitment to the external value of being an instrument of violence. My discussion seeks to illuminate martial arts practice by systematic contrast to games of sport (...) and works of performance art, especially dance. (shrink)

Godfrey-Smith advocates for linking deception in sender-receiver games to the existence of undermining signals. I present games in which deceptive signals can be arbitrarily frequent, without this undermining information transfer between sender and receiver.

In the original Ulam-Rényi game with _m_ lies/errors, Player I chooses a secret number \({\bar{x}}\) in a finite search space _S_, and Player II must guess \({\bar{x}}\) by adaptively asking Player I a minimum number of binary questions. Up to _m_ answers may be mendacious/erroneous or may be distorted before reaching Player II. In his monograph “Fault-Tolerant Search Algorithms. Reliable Computation with Unreliable Information”, F. Cicalese provides a comprehensive account of many models of the game and their applications in error-correcting (...) coding with noiseless feedback. Since for \(m>0\) lies the game is not called off by contradictory answers, and repeated answers to the same question are more informative than single answers, the underlying logic of the game with _m_ lies is not boolean. Indeed, the logic of Rényi-Ulam games is Łukasiewicz infinite-valued logic Ł \(_\infty \). In this paper we consider Ulam-Rényi games with variable numbers of lies over infinite search spaces. We characterize the MV-algebras and the unital Specker \(\ell \) -groups given by the logic of these games. (shrink)

This paper provides an existential analysis of humour as a social virtue in invasion games at the elite sport level. The main argument is that humour in this particular context can be valuable both in the competitive social training environment and in game performance. This is investigated through philosophical and psychological conceptualisations of humour that are used to reveal and analyse the appearance and possible value of a humorous approach in various social situations experienced during invasion games and (...) the associated training situations. It is concluded that humour can help balance and structure the social training environment as well as facilitate creative game performance. On this basis it is suggested that the existential perspectives on humour presented could make a fruitful contribution to talent development in the domain of invasion games. (shrink)

We study partiality in propositional logics containing formulas with either undefined or over-defined truth-values. Undefined values are created by adding a four-place connective W termed transjunction to complete models which, together with the usual Boolean connectives is shown to be functionally complete for all partial functions. Transjunction is seen to be motivated from a game-theoretic perspective, emerging from a two-stage extensive form semantic game of imperfect information between two players. This game-theoretic approach yields an interpretation where partiality is generated as (...) a property of non-determinacy of games. Over-defined values are produced by adding a weak, contradictory negation or, alternatively, by relaxing the assumption that games are strictly competitive. In general, particular forms of extensive imperfect information games give rise to a generalised propositional logic where various forms of informational dependencies and independencies of connectives can be studied.

This article contributes to the debate around the abilities of large language models such as GPT-3, dealing with: firstly, evaluating how well GPT does in the Turing Test, secondly the limits of such models, especially their tendency to generate falsehoods, and thirdly the social consequences of the problems these models have with truth-telling. We start by formalising the recently proposed notion of reversible questions, which Floridi & Chiriatti propose allow one to ‘identify the nature of the source of their answers’, (...) as a probabilistic measure based on Item Response Theory from psychometrics. Following a critical assessment of the methodology which led previous scholars to dismiss GPT’s abilities, we argue against claims that GPT-3 completely lacks semantic ability. Using ideas of compression, priming, distributional semantics and semantic webs we offer our own theory of the limits of large language models like GPT-3, and argue that GPT can competently engage in various semantic tasks. The real reason GPT’s answers seem senseless being that truth-telling is not amongst them. We claim that these kinds of models cannot be forced into producing only true continuation, but rather to maximise their objective function they strategize to be plausible instead of truthful. This, we moreover claim, can hijack our intuitive capacity to evaluate the accuracy of its outputs. Finally, we show how this analysis predicts that a widespread adoption of language generators as tools for writing could result in permanent pollution of our informational ecosystem with massive amounts of very plausible but often untrue texts.

This paper challenges Thi Nguyen's argument, in Games: Agency as Art, a central part of the value of game-play comes from the aesthetic experiences it allows, especially of our own agency, so playing a game is importantly like engaging with art. It challenges three arguments Nguyen makes in support of this view and argues, to the contrary, that the principal value in game-play rests in the achievments it allows.

This note defines Ehrenfeucht-Fraïssé games where identity is not present in the basic language. The formulation is applied to show that there is no elementary theory in the language of one binary relation that exactly characterizes models in which the relation is the identity relation.

The Grasshopper’s game-playing Utopia collapses because, ideal though it might seem to some, ultimately most of us want more out of life than game-play. Building on both The Grasshopper and the published sequels in which Bernard Suits attempts to vindicate his Utopia, the current paper reconstructs Suits’s Utopia in a new way. I start from deeper reflection on Suits’s example of John Striver, a Utopian citizen who wants to work but whose profound boredom occasions Utopia’s collapse. Although the Grasshopper returns (...) to Striver repeatedly and urges his interlocutors to bear him in mind, the case is underdeveloped and its implications undertheorized, both by Suits and his numerous commentators and critics. The Striver example reveals a picture of Utopian games as complex, dynamic, mutually responsive, and cooperative; such games are not only better for game-loving ‘Grasshoppers’ but make room in Utopia for work-loving ‘Ants’. This mutuality is the key to Utopia’s sustainability. The paper thus offers a new critique and reinterpretation of the central text in contemporary philosophy of sport and explicates the goods inherent in the ludic ideal. (shrink)

Signalling games are popular models for studying the evolution of meaning, but typical approaches do not incorporate vagueness as a feature of successful signalling. Complementing recent like-minded models, we describe an aggregate population-level dynamic that describes a process of imitation of successful behaviour under imprecise perception and realization of similar stimuli. Applying this new dynamic to a generalization of Lewis’s signalling games, we show that stochastic imprecision leads to vague, yet by-and-large efficient signal use, and, moreover, that it (...) unifies evolutionary outcomes and helps avoid sub-optimal categorization. The upshot of this is that we see ‘as-if’-generalization at an aggregate level, without agents actually generalizing. _1_ Introduction _2_ Background _2.1_ Sim-max games and conceptual spaces _2.2_ Vagueness in sim-max games and conceptual spaces _2.3_ Vagueness, functional pressure, and transmission biases _3_ Imprecise Imitation _3.1_ Replicator dynamic in behavioural strategies _3.2_ Noise-perturbed conditional imitation _4_ Exploring Imprecise Imitation _4.1_ Setting the stage _4.2_ Simulation set-up _4.3_ Measures of interest _4.4_ Results _5_ Discussion _5.1_ Levels of vagueness _5.2_ Evolutionary benefits of imprecision _5.3_ Related work _6_ Conclusion Appendix.

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.

ABSTRACTBernard Suits and other formalists endorse both the logical incompatibility thesis and the view that rule-breakings resulting in penalties can be a legitimate part of a game. This is what Fred D’Agostino calls ‘the problem of penalties’. In this paper, I reject both Suits’ and D’Agostino’s responses to the problem and argue instead that the solution is to abandon Suits’ view that the constitutive rules of all games are alike. Whereas the logical incompatibility thesis applies to games in (...) which players’ actions are perfectly controlled, it does not apply to sports. This insight not only justifies the rejection of formalism as a theory about the nature of sport but it also helps explain the greater normative complexity of sports, which in turn leads to the idea that in sports ‘cheating’ should be interpreted as a genus.

This book examines the origins and boundaries of Japanese digital role-playing games. A geographically diverse roster of contributors introduces English-speaking audiences to Japanese video game scholarship and applies postcolonial and philosophical readings to the Japanese game text.

Some video games are said to be philosophical. Despite video games having received some attention in academic philosophy, that contention has not been sufficiently addressed. This paper investigates in what sense video games might be properly called “philosophical”. To this end, I utilize Wittgenstein’s distinction between saying and showing to get into view how some video games might be properly called philosophical. This leads to two senses of being philosophical: a conventional sense of expressing philosophy through (...) propositions, i.e., through saying, and a sense of being genuinely philosophical by expressing philosophical thought through showing. I argue that the conventional sense is not sufficient to call video games philosophical, leaving the question whether there are video games which satisfy the conditions of being genuinely philosophical. I furthermore contend that there are at least some examples of video games which qualify as being philosophical, e.g., Papers, Please and The Stanley Parable. (shrink)

According to the standard objection to backward induction in games, its application depends on highly questionable assumptions about the players' expectations as regards future counterfactual game developments. It seems that, in order to make predictions needed for backward reasoning, the players must expect each player to act rationally at each node that in principle could be reached in the game, and also to expect that this confidence in the future rationality of the players would be kept by each player (...) come what may: even at the game-nodes that could only be reached by irrational play. Both expectations seem to be rather unreasonable: a player's initial disposition to rational behaviour may be weakened by a long stretch of irrational play on his part and, even more importantly, his initial confidence in the other players' future rationality may be undermined by an irrational play on their part. For different formulations of this objection see Binmore, Reny and, Bicchieri, Pettit and Sugden. and Aumann and.). (shrink)

SummaryTruth‐definitions play a crucial role in the foundations of logic and semantics. Tarsik‐type truth‐definitions are not possible to formulate in a usual first‐order language for itself, and they have been criticized because they do not account for what makes them definitions of truth. It has been suggested that truth should instead be characterized by reference to the «language‐games» of verification and falsification. The author's game‐theoretical semantics here explained for formal first‐order languages, can be thought of as a realization of (...) this idea. More technically speaking, GTS can also be thought of as a systematization of the well‐known aepsilon‐delta, definitions in the foundations of analysis. In GTS, truth is not defined by reference to winning a play of a game, but as the existence of a winning strategy in the game for the verifier. In a first‐order language, the game‐theoretical truth‐condition of a sentence S can accordingly be expressed by an explicit second‐order sentence asserting the existence of the Skolem function of S.The semantical games of GTS must be distinguished not only from the «games» of formal proof but also from the «games» in volved in our ordinary activities of verification and falsification. The latter have been modelled as games of inquiry by the author, and they are essentially epistemic games where the meaning of truth is taken for granted and where the aim of the game is to come to know certain truths. To assimilate them to the semantical games constitutive of truth is a form of Meno's paradox. (shrink)

One of the most pleasurable aspects of video games is their ability to induce immersive experiences. However, there appears to be a tentative conceptualization of what an immersive experience is. In this short review, we specifically focus on the terms of flow and immersion, as they are the most widely used and applied definitions in the video game literature, whilst their differences remain disputable. We critically review the concepts separately and proceed with a comparison on their proposed differences. We (...) conclude that immersion and flow do not substantially differ in current studies and that more evidence is needed to justify their separation. (shrink)

We propose strategic games wherein the strategies consist of players asking each other questions and answering those questions. We study simplifications of such games wherein two players simultaneously ask each other a question that the opponent is then obliged to answer. The motivation for our research is to model conversation including the dynamics of questions and answers, to provide new links between game theory and dynamic logics of information, and to exploit the dynamic/strategic structure that, we think, lies (...) implicitly inside epistemic models for epistemic languages, and to make that structure an explicit subject of logical study. Our main contributions are: the notion of a two-person question-answer game with information goals, the existence and computation of equilibria for these games, the correspondence with Bayesian games and their equilibria, and a connection between logic and game theory namely the existence of equilibria for positive goal formulae.

In previous work I’ve defended an interest-relative theory of belief. This paper continues the defence. It has four aims. -/- 1. To offer a new kind of reason for being unsatis ed with the simple Lockean reduction of belief to credence. 2. To defend the legitimacy of appealing to credences in a theory of belief. 3. To illustrate the importance of theoretical, as well as practical, interests in an interest-relative account of belief. 4. To revise my account to cover propositions (...) that are practically and theoretically irrelevant to the agent. (shrink)

Game-theoretic solution concepts describe sets of strategy profiles that are optimal for all players in some plausible sense. Such sets are often found by recursive algorithms like iterated removal of strictly dominated strategies in strategic games, or backward induction in extensive games. Standard logical analyses of solution sets use assumptions about players in fixed epistemic models for a given game, such as mutual knowledge of rationality. In this paper, we propose a different perspective, analyzing solution algorithms as processes (...) of learning which change game models. Thus, strategic equilibrium gets linked to fixed-points of operations of repeated announcement of suitable epistemic statements. This dynamic stance provides a new look at the current interface of games, logic, and computation. (shrink)

commentary on Fodor, “Against Darwinism.”.

Garry Young has made three objections against Sebastian Ostritsch’s endorsement view on the immorality of computer games. In this paper, we want to defend the endorsement view against all three of them.

We have taken a look at the rules of games in order to acquire some knowledge concerning constitutive rules and, probably, institutional phenomena in general. In this paper we tried to elaborate a system account of constitutive rules. We claim that all accounts that put emphasis on the form of rules are vulnerable. It appears that constitutive rules are interconnected and always form a system that can be internally differentiated. Thanks to adopting certain qualitative criterion we were able to (...) distinguish central and peripheral constitutive rules. Moreover, that very account makes it possible to distinguish between different types of practices that are determined by types of systems of rules. Secondly, it appears there are three “layers” of games that should not be confused: deep conventions, constitutive rules that establish the game and determine games’ identities, and “rules of efficiency” that are some sort of recommendations as to how to play well.
