Showing remarkable insight into the relationship between language and thought, Alan Turing in 1950 proposed the Imitation Game as a proxy for the question “Can machines think?” and its meaning and practicality have been debated hotly ever since. The Imitation Game has come under criticism within the Computer Science and Artificial Intelligence communities with leading scientists proposing alternatives, revisions, or even that the Game be abandoned entirely. Yet Turing’s imagined conversational fragments between human and machine (...) are rich with complex instances of inference of implied information, reasoning from generalizations, and meta-reasoning, challenges AI practitioners have wrestled with since at least 1980 and continue to study. We argue that the very fact the Imitation Game is so difficult may be the very reason it shouldn’t be changed or abandoned. The semi-decidability of the game at this point hints at the possibility of a hard limit to the powers of technology. (shrink)

This issue of the Kybernetes journal is concerned with the philosophical question- Can a Machine Think? Famously, in his 1950 paper `Computing Machinery andIntelligence' [9], the British mathematician Alan Turing suggested replacing this question - which he found \too meaningless to deserve discussion" - with a simple -behavioural - test based on an imagined `Victorianesque' pastime he entitled the`imitation game'. In this special issue of Kybernetes a selection of authors with a special interest in Turing's work (including those (...) who participated in the 2008 AISB Turing Symposium) have been invited to explore and clarify issues arising from Turing's 1950 paper on the Imitation Game; now more widely known as the Turing test.

This paper explores the potential and relevance of an innovative sociological research method known as the Imitation Game for research in health care. Whilst this method and its potential have until recently only been explored within sociology, there are many interesting and promising facets that may render this approach fruitful within the health care field, most notably to questions about the experiential knowledge or ‘expertise’ of chronically ill patients. The Imitation Game can be especially useful because (...) it provides a way to map this experiential knowledge more systematically, without falling in the dual trap of either over-relying on in-depth, but highly specific phenomenological ‘insider’-approaches that are hard to generalize, or, alternatively, problematically reducing the rich life-worlds of patients to a set of indicators in a questionnaire. The main focus of this paper is theoretical and conceptual: explaining the Imitation Game method, discussing its usefulness in the health care domain, and exploring the ways in which the approach can be utilized for chronic illness care. The paper presents both a conceptual and empirical exploration of how the Imitation Game method and its underlying theoretical concepts of ‘contributory expertise’ and ‘interactional expertise’ can be transferred from the sociological realm to the field of health care, what kinds of insights can be gained from the method, which methodological issues it may raise, and what potentially fruitful research routes can be explored. I argue that the Imitation Game can be thought of as a ‘social learning experiment’ that simultaneously enables the participants to learn from each other’s perspectives, allows researchers to explore exciting new possibilities, and also offers the tools to intervene in the practice that is being studied.

Alan Turing’s “Computing Machinery and Intelligence,” published in 1950, is one of the founding texts in the field of artificial intelligence, although the term was not coined until 1958, 4 years after his death. From the treatment of human intelligence as computational and the brain as mechanical to the comparison of animals to machines to the disregard for the materiality of computers to programming as a stand-in for procreation to fiction-inspired science, many of the core tenets that have shaped the (...) field of AI have their origins in Turing’s paper. A close analysis of the paper exposes some of the problematic logic underlying these tenets that are now proving damaging for both society and the planet. (shrink)

This paper considers undecidability in the imitation game, the so-called Turing Test. In the Turing Test, a human, a machine, and an interrogator are the players of the game. In our model of the Turing Test, the machine and the interrogator are formalized as Turing machines, allowing us to derive several impossibility results concerning the capabilities of the interrogator. The key issue is that the validity of the Turing test is not attributed to the capability of human (...) or machine, but rather to the capability of the interrogator. In particular, it is shown that no Turing machine can be a perfect interrogator. We also discuss meta-imitation game and imitation game with analog interfaces where both the imitator and the interrogator are mimicked by continuous dynamical systems. (shrink)

For many, the very idea of an artificialintelligence has always been ethicallytroublesome. The putative ability of machinesto mimic human intelligence appears to callinto question the stability of taken forgranted boundaries between subject/object,identity/similarity, free will/determinism,reality/simulation, etc. The artificiallyintelligent object thus appears to threaten thehuman subject with displacement and redundancy.This article takes as its starting point AlanTuring''s famous ''imitation game,'' (the socalled ''Turing Test''), here treated as aparable of the encounter between human originaland machine copy – the born and the (...) made. Thecultural resonances of the recent on-lineperformance of a ''Turing Test'' for computergenerated art are then explored. Arttraditionally taken to stand for all that isconsidered quintessentially human – andtherefore resistant to mechanisation –represents in this sense a kind of ''criticalcase'' in the advance of machine intelligence.The article focuses on the moral status of thebody, human agency, and social knowledge in theongoing (re-)constructions of copy, original,and of the difference between them.

An Evaluation of the 2008 Loebner Contest.

Recently there has been an unexpected rebirth of Turing's imitation game in the context of commercial demand. To meet the new requirements the following is a minimal list of what must be simulated. Real chat utterances are concerned with associative exchange of mental images. They are constrained by contextual relevance rather than by logical or linguistic laws. Time-bounds do not allow real-time construction of reasoned arguments, but only the retrieval of stock lines and rebuttals, assembled Lego-like on the (...) fly. A human agent has a place of birth, age, sex, nationality, job, family, friends, partners, hobbies etc., in short a profile. Included in the profile is a consistent personality, which emerges from expression of likes, dislikes, pet theories, humour, stock arguments, superstions, hopes, fears, aspirations etc. On meeting again with the same conversational partner, a human agent is expected to recall not only the profile, but also the gist of previous chats, as well as what has passed in the present conversation so far. A human agent typically has at each stage a main goal, of fact-provision, fact elicitation, wooing, selling, "conning" etc. A human agent also remains ever-ready to maintain or re-establish rapport by switching from goal mode to chat mode. Implementation of this last feature in a scriptable conversational agent will be illustrated. (shrink)

AI, in the form of artificial carers, provides a possible solution to the problem of a growing elderly population Yet, concerns remain that artificial carers ( such as care-or chat-bots) could not emphathize with patients to the extent that humans can. Utilising the concept of empathy perception,we propose a Turing-type test that could check whether artificial carers could do many of the menial tasks human carers currently undertake, and in the process, free up more time for doctors to offer empathy.

The widespread tendency, even within AI, to anthropomorphize machines makes it easier to convince us of their intelligence. How can any putative demonstration of intelligence in machines be trusted if the AI researcher readily succumbs to make-believe? This is (what I shall call) the forensic problem of anthropomorphism. I argue that the Turing test provides a solution. This paper illustrates the phenomenon of misplaced anthropomorphism and presents a new perspective on Turingʼs imitation game. It also examines the role (...) of the Turing test in relation to the current dispute between human-level AI and ‘mindless intelligence’. (shrink)

An evaluation of the 2008 Loebner contest.

The imitation game, the recent biopic about Alan Turing's efforts to decipher Nazi naval codes, was showered with award nominations. It even won the 2015 Academy Award for Best Adapted Screenplay. One thing it won't win any awards for, though, is its portrayal of the "imitation game" itself-Turing's proposed test of machine thinking, which hinges on whether a computer can convincingly imitate a person. The Turing test, as it is now called, doesn't really feature in the (...) file. (Given that the movie gets so much of the history wrong, perhaps that's a good thing). (shrink)

In the 1950s, Alan Turing proposed his influential test for machine intelligence, which involved a teletyped dialogue between a human player, a machine, and an interrogator. Two readings of Turing's rules for the test have been given. According to the standard reading of Turing's words, the goal of the interrogator was to discover which was the human being and which was the machine, while the goal of the machine was to be indistinguishable from a human being. According to the literal (...) reading, the goal of the machine was to simulate a man imitating a woman, while the interrogator – unaware of the real purpose of the test – was attempting to determine which of the two contestants was the woman and which was the man. The present work offers a study of Turing's rules for the test in the context of his advocated purpose and his other texts. The conclusion is that there are several independent and mutually reinforcing lines of evidence that support the standard reading, while fitting the literal reading in Turing's work faces severe interpretative difficulties. So, the controversy over Turing's rules should be settled in favor of the standard reading. (shrink)

To assess the intelligence of machines, Alan Turing proposed a test of imitation known as the imitation game, famously known as the Turing test. To assess whether artificial intelligent (AI) systems could be moral or not, Colin Allen et al. developed a test of imitation in the context of morality, a test known as the Moral Turing Test (MTT), which I will, in this paper, call the moral imitation game. There are arguments against developing (...) any type of MTT or moral imitation game. Rather than developing a moral imitation game, this paper proposes a criterion of imitation for AI systems in the moral scenario. To develop a criterion of imitation, I explore the notion of moral attribution in detail. Within the case of moral attribution, I introduce the subject‐ascriber distinction. The notion of moral attribution and the subject‐ascriber distinction is employed to address the following questions: (a) how is the assessment in MTT arranged?, (b) what is the role of the interrogator in the MTT?, and (c) what information is to be concealed from the interrogator? The first question deals with the aspect of assessment, the second question deals with the reordering of the role of the interrogator and the third one deals with the concealment aspect of the imitation game. After that, a criterion of imitation for AI systems is put forward. Using the subject‐ascriber distinction in moral attribution and David Lewis' Mad Pain and Martian Pain cases, it is argued that the notion of sentience is insignificant for the ascriber for moral attributions.

This essay delves into Alan Turing's "Computing Machinery and Intelligence", examining the entrenched the binary opposition between human and machine. Through deconstruction, the essay seeks to reveal and analyze the deeper insights inherent in Turing's work. Of particular significance is Turing's equivalence between language and thought, particularly in the context of the imitation game. Within the grammatological realm of Turing's text, writing and mechanism are nearly interchangeable, representing the intersection of humans and machines. By adopting a deconstructive perspective, (...) the essay illuminates the philosophical origins of the artificial intelligence debates and their implications for our understanding of human existence.

Twenty years ago in "Turing's Two Tests for Intelligence" I distinguished two distinct tests to be found in Alan Turing's 1950 paper "Computing Machinery and Intelligence": one by then very well-known, the other neglected. I also explained the significance of the neglected test. This paper revisits some of the points in that paper and explains why they are even more relevant today. It also discusses the value of tests for machine intelligence based on games humans play, giving an analysis of (...) some twentieth century TV game shows and how they relate to the tests for machine intelligence in Turing's paper and in some other tests for machine intelligence that have been proposed since. Their value in distinguishing between 'wise' and simply ‘clever’ AI is discussed. (shrink)

In "The Status and Future of the Turing Test" (Moor, 2001), which appeared in an earlier issue of this journal, James Moor remarks on my paper "Turing's Two Tests for Intelligence." In my paper I had claimed that, whatever Turing may or may not have thought, the test described in the opening section of Turing's now legendary 1950 paper "Computing Machinery and Intelligence" is not equivalent to, and in fact is superior to, the test described in a passage that occurs (...) much later in Turing's paper (i.e., in Section 5 of Turing, 1950). I'm pleased Moor chose to give such prominence to my point, and very happy to see that he recognized that my claim was a normative one about the superiority of one test over another, rather than a claim about Turing's intentions. However, as I think the way he describes my point could lead to misunderstandings, I'd like to clarify the points I made. One major clari?cation is which two tests I am contrasting; another is that the difference in overall structure of the two tests is of philosophical signi?cance. (shrink)

A significant increase in the probability of an action resulting from observing that action performed by another agent cannot, on its own, provide persuasive evidence of imitation. Simple models of social influence based on two-person sequential games suggest that both imitation and pseudo-imitation can be explained by a process more fundamental than priming, namely, subjective utility maximization.

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.

We study repeated normal form games where the number of players is large. We argue that it is interesting to look at such games as being divided into subgames, each of which we call a neighbourhood. The structure of such a game is given by a graph G whose nodes are players and edges denote visibility. The neighbourhoods are maximal cliques in G. The game proceeds in rounds where in each round the players of every clique X of (...) G play a strategic form game among each other. A player at a node v strategises based on what she can observe, i.e., the strategies and the outcomes in the previous round of the players at vertices adjacent to v. Based on this, the player may switch strategies in the same neighbourhood, or migrate to another neighbourhood.We are interested in addressing questions regarding the eventual stability of such games. We incrementally impose constraints on the ‘types’ of the players. First, we look at players who are unconstrained in their strategising abilities, in that, players who may use unbounded memory. We then consider the case of memoryless players. We show that in both these cases the eventual stability of the game can be characterised in terms of potentials. We then introduce a simple modal logic in which the types of the players can be specified. We show that when the players play according to these specified types, it can be effectively decided whether the game stabilises. Finally, we look at the important heuristic of imitation. Simple imitative strategies can be specified in the logic introduced by us. We show that in a population of optimisers and imitators, we can decide how ‘worse-off’ the imitators are by playing imitative strategies rather than optimal ones. (shrink)

Psychologically faithful deep neural networks (DNNs) could be constructed by training with psychophysics data. Moreover, conventional DNNs are mostly monocular vision based, whereas the human brain relies mainly on binocular vision. DNNs developed as smaller vision agent networks associated with fundamental and less intelligent visual activities, can be combined to simulate more intelligent visual activities done by the biological brain.

Turing’s Imitation Game is often viewed as a test for theorised machines that could ‘think’ and/or demonstrate ‘intelligence’. However, contrary to Turing’s apparent intent, it can be shown that Turing’s Test is essentially a test for humans only. Such a test does not provide for theorised artificial intellects with human-like, but not human-exact, intellectual capabilities. As an attempt to bypass this limitation, I explore the notion of shifting the goal posts of the Turing Test, and related tests such (...) as the Total Turing Test, away from the exact imitation of human capabilities, and towards communication with humans instead. While the continued philosophical relevance of such tests is open to debate, the outcome is a different class of tests which are, unlike the Turing Test, immune to failure by means of sub-cognitive questioning techniques. I suggest that attempting to instantiate such tests could potentially be more scientifically and pragmatically relevant to some Artificial Intelligence researchers, than instantiating a Turing Test, due to the focus on producing a variety of goal directed outcomes through communicative methods, as opposed to the Turing Test’s emphasis on ‘fooling’ an Examiner.

In lieu of an abstract, here is a brief excerpt of the content:Wittgenstein’s Reflection in Lewis Carroll’s Looking-GlassLeila S. MayAccording to one tradition in the theory of fiction, there is a kind of fantasy whose function is to invite the reader to "acknowledge the possibility of a different reality."1 In this essay I want to ask whether Lewis Carroll's Alice books fit into this category; that is, I want to explore the possibility that Alice's Adventures in Wonderland and Through the (...) Looking-Glass are not the pure nonsense that many readers take them to be. In considering the Alice books as fantasy offering a view of a "different reality" I do not deny that there are in these stories some mimetic elements alongside the fantastic—representations of things going on somewhere, somehow, in Victorian society—in which case the "different reality" presented will not be so terribly different as to be unrecognizable. For example, the Mad Tea Party in Alice's Adventures in Wonderland is not only an act of fantasy but also an act of mimesis. It certainly imitates the real tea parties often held throughout Victorian England—if caricature is a form of imitation—but it may also mime those mock tea parties held in English asylums whose goal was to model sane-like behavior to the inmates.2 An analogous question can be asked about Carroll's books in general: In addition to the component of fantasy, are they mimetic of Victorian culture itself, or merely of the Victorian conception of madness? Michel Foucault has argued that, while the very idea of la folie is an historical construct, the dialectical relationship between reason and unreason, with each pole parasitic on the other, is a structural constant. Carroll's Alice books produce images that are discharged in the confused nineteenth-century landscape where these two opposites meet. In that respect, his books are not so different from many of the more standard novels written in mid-century England. In this essay I [End Page 79] will explore features of this landscape, using a theoretical framework that has been synthesized from a number of related claims in the work of the linguistic philosopher Ludwig Wittgenstein. In addition to my long-range aim of urging further study of Wittgenstein's work by literary critics, one of my specific goals is to show that the application of Wittgensteinian methods to the works of Lewis Carroll reveals something about the hidden logic of Carroll's stories, and conversely that this procedure tests some of Wittgenstein's intuitions concerning language. Yet another goal is to suggest that the structure of the discourse of domesticity as reflected in many mid-nineteenth-century novels is curiously similar to the structure of discourse in Wonderland and Looking-Glass Land—that the language-games played at these sites are at the same time functional and dysfunctional in much the same way. That may seem like a lot to attempt in a few pages,... but to paraphrase Humpty-Dumpty, when I ask words to do that much extra work, I pay them overtime.In 1965 the philosopher George Pitcher published an essay, "Wittgenstein, Nonsense, and Lewis Carroll," in which he sought to demonstrate "the remarkable extent and depth of affinity between these two great writers with respect to nonsense." In addition, he showed that "the very same confusions with which Wittgenstein charged philosophers were deliberately employed by Carroll for comic effect," and that many of the examples that Wittgenstein used to illustrate his points "resemble, in varying degrees, examples that are found in the works of Carroll."3 While I agree with Pitcher's observation that the examples of nonsense that Wittgenstein offers are very similar to a primary strain of nonsense that runs through the Alice books, in the first section I intend to go beyond that observation and to apply some of Wittgenstein's tools to Carroll's work and show that Wittgenstein's work can be used to reveal features of literary narrative that might otherwise be obscured, and in the second section, to apply these tools to the works of fiction this side of the Looking-Glass.IWittgenstein says that a language is a "language-game." He... (shrink)

In their enthusiasm for programming, computational linguists have tended to lose sight of what humansdo. They have conceived of conversations as independent of sound and the bodies that produce it. Thus, implicit in their simulations is the assumption that the text is the essence of talk. In fact, unlike electronic mail, conversations are acoustic events. During everyday talk, human understanding depends both on the words spoken and on fine interpersonal vocal coordination. When utterances are analysed into sequences of word-based forms, (...) however, these prosodic aspects of language disappear. Therefore, to investigate the possibility that machines might talk, we propose acommunion game that includes this interpersonal patterning. Humans and machines would talk together and, based on recordings of them, a panel would appraise the relevant merit of each machine's simulation by how true to life it sounded. Unlike Turing's imitation game, the communion game overtly focuses attention, not on intelligence, but on language. It is designed to facilitate the development of social groups of adaptive robots that exploit complex acoustic signals in real time. We consider how the development of such machines might be approached. (shrink)

The fast development of synthetic media, commonly known as deepfakes, has cast new light on an old problem, namely—to what extent do people have a moral claim to their likeness, including personally distinguishing features such as their voice or face? That people have at least some such claim seems uncontroversial. In fact, several jurisdictions already combat deepfakes by appealing to a “right to identity.” Yet, an individual’s disapproval of appearing in a piece of synthetic media is sensible only insofar as (...) the replication is successful. There has to be some form of identity between the content and the natural person. The question, therefore, is how this identity can be established. How can we know whether the face or voice featured in a piece of synthetic content belongs to a person who makes claim to it? On a trivial level, this may seem an easy task—the person in the video is A insofar as he or she is recognised as being A. Providing more rigorous criteria, however, poses a serious challenge. In this paper, I draw on Turing’s imitation game, and Floridi’s method of levels of abstraction, to propose a heuristic to this end. I call it the identification game. Using this heuristic, I show that identity cannot be established independently of the purpose of the inquiry. More specifically, I argue that whether a person has a moral claim to content that allegedly uses their identity depends on the type of harm under consideration. (shrink)

To reveal the mechanisms of firms’ technological strategic choices between innovation and imitation, an evolutionary game model is proposed from the perspective of the behavioral biases. First, behavioral biases such as reference point dependence, loss aversion, and probability weighting can be defined and modeled based on the prospect theory. Second, according to the firm theory, a Cournot or Stackelberg game modeled with a technology spillover effect and intellectual property protection is applied to portray the interaction between firms. (...) Third, an improved evolutionary game model is provided by incorporating behavioral biases into the framework of the decision-making process. Finally, the simulation analysis of some important factors, such as intellectual property protection, patent fees, innovation risks, decision-making attitudes, and consumers’ price preference on firms’ technological strategic choices, is presented. The corresponding results show that innovation risk is an important factor affecting the technological strategic choices of firms, increasing the intellectual property protection and the patent fee for technology transfer can effectively control the spillover effect of technology, there is a partial U-shaped relationship between the consumers’ price preference and innovation, and the behavioral biases such as reference point dependence, loss aversion, and probability weighting will change the perception of payoff and risk and will eventually induce firms to adopt the innovation strategy.

We focus on the evolution of action capabilities which set the stage for language, rather than analyzing how further brain evolution built on these capabilities to yield a language-ready brain. Our framework is given by the Mirror System Hypothesis, which charts a progression from a monkey-like mirror neuron system (MNS) to a chimpanzee-like mirror system that supports simple imitation and thence to a human-like mirror system that supports complex imitation and language. We present the MNS2 model, a new (...) model of action recognition learning by mirror neurons of the macaque brain and augmented competitive queuing, a model of opportunistic scheduling of action sequences as background for analysis of modeling strategies for simple imitation as seen in the great apes and complex/goal-directed imitation as seen in humans.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.2 (2003) 382-401 [Access article in PDF] Symposium:the Ancients Now Bo Earle Plato, Aristotle, and the Imitation of Reason THE DEBATE BETWEEN the philosophers and the poets was already "ancient" when Plato made his contribution. 1 Yet, as an ostensibly analytical "debate," there is a sense in which this dispute was always rigged in the philosophers' favor. This is due to the fact that an (...) integral part of philosophy consists in accounting for philosophy's place among the other disciplines and practices, whereas such accounting is not necessarily a part of poetry. Consequently, framing the debate in these terms obscures what is really at stake in it. For, what has made poetry such a longstanding source of irritation for philosophers is not that it pretends to offer an alternative account of the order of the disciplines and practices, but precisely that it does not pretend to offer such an account, does not engage that pursuit. The most obvious way to juxtapose Plato and Aristotle with respect to this difference is to say that Plato saw it as a difference of incompatibility, Aristotle as one of complementarity. But this is again already to approach the issue on the philosopher's terms. On the other hand, saying that poetry simply defies philosophical containment can all too easily lead to a romantic valorization of incommensurability that merely inverts Plato's repudiation. The following attempts to show that the tension between philosophy and poetry is registered by Plato's and Aristotle's philosophies of [End Page 382] poetry in a way that doctrines of complementarity and incommensurability cannot explain, and that thus illustrates both the ethical stakes of philosophical praxis, and the philosophical value of poetic elucidation of such praxis.Plato's philosophical objection to poetic imitation is two-fold, based in metaphysics and epistemology, on the one hand, and in ethics, on the other. The metaphysical-epistemological objection is that poetry has no stake in truth and thus cannot contribute to knowledge. There is no way of distinguishing valid from invalid interpretations of poems, Socrates complains in Protagoras, because the poets do not submit to dialectical interrogation about their work: "we cannot ask them questions about what they say." 2 If they cannot account for what they do, Socrates concludes that the work of the poets should be counted among the phenomena of nature and the acts of gods: "poets do not compose their poems with knowledge, but by some inborn talent and by inspiration, like seers and prophets." 3 Socrates criticizes poetry for seeming to penetrate the world's mysteries when it in fact propagates them.Yet Socrates' claim is not that poetry makes us take something to be true that actually is false. Rather, his point is that poetry simply has no stake in the truth to begin with. The problem with debates about poetry, Socrates continues in Protagoras, is that the disputants "wind up arguing about something they can never finally decide" (347e); consequently Socrates proposes that we "should put the poets aside and converse directly with each other, testing the truth and our own ideas" (Pr, 348a). The subject matter presented to us by poetry is directly contrasted with that which admits of dialectical truth-testing. That is, poetry does not "lie," it does not disguise falsehoods as truths; rather, it turns its back on the pursuit of truth altogether. It is something with respect to which truth oriented arguments "can never finally be decided" because it is something to which the category of truth does not apply. Indeed, our interest in poetic imitation derives precisely from the fact that such imitation does not pretend to be what it imitates, that it is liberated, in a sense, from the question of 'the truth' of the things, people and events it imitates belong. Since the poet offers "no worthwhile knowledge of the things he imitates," Socrates concludes that poetic "imitation is a kind of game and not something to be taken seriously" (R, 602b). Such imitation is disengaged from the realm of knowledge and truth-testing entirely, constituting an... (shrink)

A series of experiments involving two and three-player repeated guessing games with unique equilibrium is conducted. We find that equilibrium behavior is observed less frequently and overall choices are farther from the equilibrium in two-player asymmetric games in contrast to symmetric games, but this is not the case in three-player games. Convergence towards equilibrium exists in all cases but asymmetry slows down the speed of convergence to the equilibrium in two, but not in three-player games. Furthermore, the strong players have a slight earning advantage over the weak players, and asymmetry increases the discrepancy in choices (defined as the squared distance of choices from the winning number) in both games.

The process learning for adults training joins in a space/time which can be considered as « communicative action ». Learning is for us a part of a space of sense referred to the notion of passage and thus process. It is well known today that one of its modalities, for adults as for children, leans on the imitation. On the other hand, the game of the interactions makes that the learnings are not passed on without an autonomous and (...) mediate renegotiation of the subjects (vicariant learning). This relation between the partners will base itself on characteristics which allow to understand the interpretation as a modality, an essential medium to an «emancipator learning». On that basis, the constructed knowledge, the knowledge in elaboration, engages a conversion of the look in the training for adults, but also that of the learner towards an empowerment of a subject and his emancipation.

Lewis signalling games are often used to explain how it is possible for simple agents to develop systems of conventional semantic meaning. In these games, all players obtain identical payoffs in every outcome. This is an unrealistic payoff structure, but it is often employed because it is thought that semantic meaning will not emerge if interests conflict. Here it is shown that not only is conventional meaning possible when interests conflict, but it is the most likely outcome in a finite (...) population model of learning known as the Moran process. On the basis of this result it is suggested that evolutionary game theory’s standard models may yield results that are systematically distorted for a class of signalling games that have the abstract structure of social dilemmas. 1 Introduction2 The Seduction Game3 Imitation Dynamics with Small Mutations4 Dynamics with Unverifiable Message5 Analysis of a Related Three-Strategy Game6 Conclusion.

How do conventions of communication emerge? How do sounds or gestures take on a semantic meaning, and how do pragmatic conventions emerge regarding the passing of adequate, reliable, and relevant information? My colleagues and I have attempted in earlier work to extend spatialized game theory to questions of semantics. Agent-based simulations indicate that simple signaling systems emerge fairly naturally on the basis of individual information maximization in environments of wandering food sources and predators. Simple signaling emerges by means of (...) any of various forms of updating on the behavior of immediate neighbors: imitation, localized genetic algorithms, and partial training in neural nets. Here the goal is to apply similar techniques to questions of pragmatics. The motivating idea is the same: the idea that important aspects of pragmatics, like important aspects of semantics, may fall out as a natural results of information maximization in informational networks. The attempt below is to simulate fundamental elements of the Gricean picture: in particular, to show within networks of very simple agents the emergence of behavior in accord with the Gricean maxims. What these simulations suggest is that important features of pragmatics, like important aspects of semantics, don't have to be added in a theory of informational networks. They come for free. (shrink)
