This article addresses the ability of Parallel Distributed Processing (PDP) networks to generate stagewise cognitive development in accordance with Piaget's theory of cognitive epigenesis. We carried out a replication study of the simulation experiments by McClelland (1989) and McClelland and Jenkins (1991) in which a PDP network learns to solve balance scale problems. In objective tests motivated from catastrophe theory, a mathematical theory of transitions in epigenetical systems, no evidence for stage transitions in network performance was found. It (...) is concluded that PDP networks lack the ability to recover the positive outcomes of analogous catastrophe analyses of real cognitive developmental data. In an attempt to further characterize the learning behaviour of PDP networks, we carried out a second simulation study using the discrimination‐shift paradigm. The results thus obtained indicate that PDP learning is compatible with the learning of stimulus‐response relationships, not with the acquisition of mediating rules such as conceived in (neo‐)Piagetian theory. In closing, we speculate about the feasibility of simulating stagewise development with alternative network architectures. (shrink)

The construction of the modern subject and the pursuit of human freedom and autonomy, as well as the practice of human science has been pivotal in the development of modern education. But for Foucault, the subject is only the effect of discourses and power?knowledge arrangements, and modern human science is part of the very arrangement that has given birth to the subject who is thoroughly subjected. In his final years, however, a strong passion for human liberty reemerged, and he proposed (...) that a different truth game, the ancient ethical truth practices may actually constitute a self that is free and enjoys self-mastery. In this article, I analyze how modern human science, exemplified by Piaget's child developmental research, has become the means of unfreedom and domination and discuss the ancient ethical truth games Foucault so admired and how they bring self-mastery and freedom to the self. Furthermore, I discuss whether liberal education can ground its notions of autonomy and liberty on the Foucauldian concept of the subject and truth games. (shrink)

Through the use of Bayesian probability theory and Communication theory, a formal mathematical model of a Churchmanian Dialectical Inquirer is developed. The Dialectical Inquirer is based on Professor C. West Churchman's novel interpretation and application of Hegelian dialectics to decision theory. The result is not only the empirical application of dialectical inquiry but also its empirical (i.e., scientific) investigation. The Dialectical Inquirer is seen as especially suited to problems in strategic policy formation and in decision theory. Finally, specific application (...) of the inquirer is made to Popper's notions for ‘The Test of Severity’ of a scientific theory. (shrink)

This book synthesizes the game-theoretic modeling of decision-making processes and an ancient moral requirement, called the Golden Rule of ethics (GR). This rule states, "Behave to others as you would like them to behave to you." The GR is one of the oldest, most widespread and specific moral requirements that appear in Christianity, Islam, Judaism, Buddhism, and Confucianism. The book constructs and justifies mathematical models of dynamic socio-economic processes and phenomena that reveal the mechanism of the GR and (...) are based on the concept of Berge equilibrium. The GR can be naturally used for resolving or balancing conflicts, and its "altruistic character" obviously excludes wars, blood-letting, and armed clashes. The previous book of the authors, The Berge Equilibrium: A Game-Theoretic Framework for the Golden Rule of Ethics, covers the static case of the GR. In this book, the dynamic case of the GR is investigated using the altruistic concept of Berge equilibrium and three factors as follows: a) a modification of N.N. Krasovskii's mathematical formalization of differential positional games (DPGs), in view of the counterexamples given by A.I. Subbotin and A.F. Kononenko; b) the method of guiding control, proposed by N.N. Krasovskii; c) the Germeier convolution of the payoff functions of different players. Additionally, the book features exercises, problems, and solution tips collected together in Appendix 1, as well as new approaches to conflict resolution as presented in Appendices 2-4. The book will be of use to undergraduate and graduate students and experts in the field of decision-making in complex control and management systems, as well as anyone interested in game theory and applications.

Locality notions in logic say that the truth value of a formula can be determined locally, by looking at the isomorphism type of a small neighbourhood of its free variables. Such notions have proved to be useful in many applications. They all, however, refer to isomorphisms of neighbourhoods, which most local logics cannot test. A stronger notion of locality says that the truth value of a formula is determined by what the logic itself can say about that small (...) neighbourhood. Since the expressiveness of many logics can be characterized by games, one can also say that the truth value of a formula is determined by the type, with respect to a game, of that small neighbourhood. Such game-based notions of locality can often be applied when traditional isomorphism-based notions of locality cannot.Our goal is to study game-based notions of locality. We work with an abstract view of games that subsumes games for many logics. We look at three, progressively more complicated locality notions. The easiest requires only very mild conditions on the game and works for most logics of interest. The other notions, based on Hanf’s and Gaifman’s theorems, require more restrictions. We state those restrictions and give examples of logics that satisfy and fail the respective game-based notions of locality. (shrink)

Abstract: In the course of seeking an answer to the question "How do you know you are not a zombie?" Floridi (2005) issues an ingenious, philosophically rich challenge to artificial intelligence (AI) in the form of an extremely demanding version of the so-called knowledge game (or "wise-man puzzle," or "muddy-children puzzle")—one that purportedly ensures that those who pass it are self-conscious. In this article, on behalf of (at least the logic-based variety of) AI, I take up the challenge—which (...) is to say, I try to show that this challenge can in fact be met by AI in the foreseeable future.

Traditional theories of autonomy argue for rational agents who are free to make decisions about the moral law and justice. Adopting these theories entails that children lack of autonomy; they are not fully developed rational agents, and, because of that, they are unable to engage in the complex cognitive capacities required by autonomy, such as critical self-reflection or substantive independence. Amy Mullin who, as part of a new area of philosophy called Philosophy of Childhood, argues for granting (...) class='Hi'>children minimal or local autonomy. She argues that children's attachments to those they love can be a source of autonomy in a minimal sense. She claims that it is in the relationship with those the child loves that the child is able to find meaningful activities and is able to care for someone or something. I argue that Jeff Lemire’s Essex County Vol. 1 Tales from the Farm, is a depiction of childhood that illustrates Mullin’s ideas. However, I will argue that through the use of images as a form of language, Lemire offers an insight that is unique to the medium of the graphic novel. Lemire as an artist negotiates the optical physical surfaces and uses these surfaces as a language to bridge the gap between the child and the adult and help us understand the mind of children as autonomous agents. This is an important contribution since it will allow us to understand how children can demonstrate autonomy in some of the ways in which they conduct their lives and how this may be reason enough to grant them a voice when decisions that would affect their lives are made on their behalf, such as custody cases or end of life decisions.

Knowledge before belief ascription? Yes and no (depending on the type of “knowledge” under consideration). In an influential paper, Jonathan Phillips and colleagues have recently presented a fascinating and provocative big picture that challenges foundational assumptions of traditional Theory of Mind research (Phillips et al., 2020). Conceptually, this big picture is built around the main claim that ascription of knowledge is primary relative to ascription of belief. The primary form of Theory of Mind (ToM) thus is so-called factive ToM that (...) centres around knowledge-related mental states that are true rather than meta-representational ToM that centres around subjective epistemic states like belief that may or may not be true (Nagel, 2017; Phillips & Norby, 2019). Empirically, Phillips and colleagues build on converging findings from different areas: Ample research in developmental psychology shows that children track who has had informational access to events (and thus knows about the events) before they keep track of others’ potentially false beliefs (e.g., Perner & Roessler, 2012). Many studies from comparative psychology have found evidence that non-human great apes keep track of others’ perceptual and informational access while there is no convincing evidence that they keep track of others’ beliefs (Horschler et al., 2020; Martin & Santos, 2016; Call & Tomasello, 2008). And, work from cognitive psychology and experimental philosophy suggests that adults are faster, for example, to judge what others know than to judge what they believe (Phillips et al., 2018).In this commentary, we would like to critically evaluate and friendly amend the claims put forward by Phillips and colleagues. Conceptually, while we agree that some form of factive Theory of Mind is primary, we would like to raise doubts whether this primary factive ToM already involves full-fledged knowledge ascription. Empirically, we will point to potential test cases that are suitable to test Phillips and colleagues’ account against the friendly amendment proposed here. Is knowledge ascription really primary relative to belief ascription?We agree that the empirical findings reviewed by Phillips and colleagues do make a strong case for the conjecture that some form of factive ToM is indeed (phylogenetically, ontogenetically, and cognitively) primary. But we suspect that this claim, in unqualified form, may be somewhat incomplete and misleading. There is not necessarily one unitary form of factive ToM, and one notion of “knowledge“ in play across development and evolution, and perhaps not even in adults‘ Theory of Mind. This suspicion builds on several foundations: First, from an empirical point of view there have been, as highlighted by the authors, characteristic U-shaped developmental curves in some tasks of factive ToM – often a reliable indicator that different underlying processes are in play (Karmiloff-Smith, 1992). Second, from a theoretical point of view, conceptual change and dual process approaches to ToM and other forms of social cognition have highlighted the possibility of more complex developmental trajectories such that earlier and more basic forms of a conceptual competence may be supplemented and superseded by later and more sophisticated refinements (e.g. Apperly & Butterfill, 2009; Perner, 1991). For the case of factive ToM, it may be that there is a basic and primitive notion of “knowledge“ in place early in ontogeny (and perhaps phylogenetically more ancient) that shares some of the essential features of our mature “knowledge” concept: “knowledge” in this broad sense, as emphasized by the authors, is factive, not modality-specific, and allows for representations of egocentric ignorance. For this basic concept, the slogan “knowledge before belief“ may well be true. However, this basic concept need not yet be our mature notion of knowledge proper and thus this basic form of factive ToM may fall crucially short of our adult form of factive ToM. Why? Because essential elements of our mature concept of knowledge are still missing: First of all, while so-called Gettier cases and other considerations make clear that knowledge does not reduce to justified true belief (one can have justified true beliefs that still do not amount to knowledge; Gettier, 1963), according to many accounts knowledge at least presupposes justified true belief. Correspondingly, ascription of knowledge would thus presuppose ascription of belief. Now, we understand that this is one of the very traditional assumptions that Phillips and colleagues challenge, and given space restrictions we will not focus on it here any further (see, e.g, Rose & Schaffer, 2013). But there is a second crucial aspect of knowledge proper that is missing from the basic notion: knowledge proper is aspectual, and consequently reports of knowledge proper are intensional, while neither seems to be the case of basic knowledge and reports of it. Knowledge proper is aspectual in the following sense: whether or not someone knows something depends on how, under which aspects, she has had informational access to a given scene. Suppose Eve has seen Clark Kent enter the house. Does she know that Superman is in the house? It depends. If she knows about the identity Clark Kent = Superman, she does, otherwise she does not. Consequently, knowledge ascription is intensional in the sense that the substitution of co-referential terms is not necessarily truth-value preserving: “Eve knows that Clark Kent is in the house“ does not imply “Eve knows that Superman is in the house”.Now, from the point of view of cognitive development, much research suggests that children’s appreciation of the aspectuality of propositional attitudes (and the intensionality of propositional attitude reports) develops in protracted ways not before the age of four (e.g., Apperly & Robinson, 1998; Rakoczy et al., 2015; Proft et al., 2019). In fact, recent studies suggest that around age four children undergo a fundamental and coherent cognitive revolution: they acquire a solid meta-representational notion of propositional attitudes that allows them to ascribe subjective aspectual representations that may or may not be accurate: Children come to solve false belief tasks that require belief ascription at the same time as tasks that require an understanding of aspectuality, and there is strong convergence/correlation between these different tasks (Rakoczy, 2017; Rakoczy et al., 2015). These considerations thus evoke a somewhat modified picture of the developmental course of factive Theory of Mind: Some form of factive ToM, indeed, comes first (developmentally and phylogenetically). In this primary stage, subjects track agents‘ cognitive relations to the world that display some of the essential signatures of knowledge proper (factive; not modality-specific; allow for representations of egocentric ignorance). Various approaches in ToM research over the last years have aimed at describing this basic form of knowledge-like relations, for example in terms of “cognitive connections“ (Flavell, 1988), “registration“ (Apperly & Butterfill, 2009), “experiential records“ (Perner & Roessler, 2012) or “awareness relations“ (Martin & Santos, 2016). While differing in focus and details, all these accounts converge in stressing one crucial point: this early form of factive ToM allows observer to keep track of what others have or have not witnessed and, in this sense, what they do or do not know. It allows, in other words, so-called “Level I” perspective-taking (Flavell, 1977): understanding what others see. But this early form of factive ToM still falls short of knowledge ascription proper because it lacks an appreciation of the essential aspectuality of propositional attitudes in general and of knowledge in particular. In other words, it does not yet allow for “Level II” perspective-taking: understanding how different agents may represent a given scene (Fizke et al., 2017; Low & Watts, 2013; Oktay-Gür et al., 2018). Only later, around age 4, do children then develop the new meta-representational framework of propositional attitudes that goes beyond basic factive ToM. Once they have this framework and thus an understanding of aspectuality at hand, they can extend their initial and primary factive ToM to acquire the mature concept of knowledge (as at least presupposing true, justified belief, where belief is necessarily aspectual). So, while basic knowledge ascription indeed precedes belief ascription, full-blown attribution of aspectual knowledge develops in tandem with belief attribution. Or in other words: basic factive ToM precedes full-blown meta-representational ToM but full-blown factive ToM does not (since it is itself a part of full-blown meta-representational ToM). Empirical outlookThis slightly modified picture raises many interesting new empirical questions, and makes competing predictions relative to the picture put forward by Phillips and colleagues: From developmental and comparative perspectives, the modified picture would predict that “knowledge before belief” only applies for a circumscribed set of knowledge-related situations: those in which knowledge ascription does not require sensitivity to the aspectuality of knowledge (does not require distinguishing, for example, “Does she know that Clark Kent is in the house?” vs. “Does she know that Superman is in the house?”) and is limited to Level I perspective-taking. Young children before the age of four and non-human primates should be able to solve such non-aspectual knowledge ascription problems. But only older children from around age four, once they have acquired the full-fledged conceptual apparatus of meta-representation, should be able to handle aspectual knowledge ascription. Regarding adult functioning, the most fundamental question is: Do adults operate with one unitary factive ToM, as Phillips and colleagues assume? Or are there two kinds of factive ToM throughout the lifespan, as our modified picture suggests? In particular, does the more basic version remain in operation in adulthood, perhaps even as the default mode, that reveals itself under conditions of speeded responses, limited cognitive resources etc.? If the latter were true, specific performance patterns should be found. First, results such that adults are faster at knowledge ascription than at belief ascription (as found in Phillips et al., 2018) should be restricted to designs where knowledge ascription does not require any considerations of aspectuality. In such designs (as they were used in Phillips et al., 2018), subjects can make use of their primordial (non-aspectual) factive ToM in knowledge ascription, but have to use their full-fledged (aspectual) ToM in belief ascription. However, in new cases in which knowledge ascription is potentially aspectual (“Does Eve know that Superman is in the house?”), the speed difference between knowledge and belief ascription should vanish since both now require full-fledged (aspectual) ToM. Second, and relatedly, fast factive ToM should have characteristic signature limits to do with the lacking appreciation of aspectuality (Apperly & Butterfill, 2009; Low et al., 2016): Subjects under speeded conditions (or in dual task formats in which their central cognitive resources are taxed) should be unable to systematically distinguish between “Eve knows that Clark Kent is the house” (true) and “Eve knows that Superman is in the house” (possibly true). No such signature limits should be expected, in contrast, under reflective conditions in which subjects can use their full-fledged and mature factive ToM. Interestingly, these hypothetical developmental and adult performance patterns would correspond to similar patterns found in the domain of modal judgments. Adults, it seems, have two notions of modality at their disposal: a more primitive (ontogenetically old) default notion that does not differentiate between descriptive and normative modals and thus yield characteristic signature limits; and more differentiated and nuanced notions (ontogenetically more recent) that do sharply distinguish between different forms of modality. What works fast and gets addressed in speeded tasks is the primitive default notion (in speeded tasks, adults tend to confuse what is possible with what is permitted, for example, in the way very young children do) whereas the more nuanced notions reveal themselves in reflective task settings in which adults are not subject to such confusions (Phillips & Cushman, 2017). Modality judgments and factive ToM may thus reveal striking analogies. Just like in the area of modality, then, there may be basic and default factive ToM, present from early on and in operation throughout the lifespan in speeded responses (and under other conditions of limited cognitive resources), and more sophisticated factive Theory of Mind that develops later on the basis of full-fledged meta-representation and that reveals itself in more reflective judgements.

The purpose is to solve the problem that the current research on the impact of the microstructure of mental elasticity and its constituent factors on the development of the mental elasticity of children is not comprehensive, and the traditional artificial analysis method of mental problems has strong subjectivity and low accuracy. First, the structural equation model is used to study the microstructure of poor children's mental elasticity, and to explore the structural relationship and functional path between the mental (...) elasticity of children and the self-efficacy of their mental health, psychological anxiety, and attachment. Second, a prediction model of mental problems of children in plight based on the backpropagation neural network is constructed. Finally, middle schools in the representative areas of Northwest China are selected as the research unit. The relevant research data are collected by issuing questionnaires, and the data set is constructed to verify the performance of the model. The experimental results show that the average prediction errors of the BPNN model and the support vector regression model are 1.87 and 5.4, respectively. The error of BPNN is 65.4% lower than that of SVR, so BPNN has a better performance. The prediction results of the test set show that the actual error and the relative error of the BPNN model are controlled in the range of 0.01, and the prediction accuracy is high. The structural equation model has a high fitting degree. The results of the questionnaire analysis show that attachment, self-efficacy, and psychological anxiety exert a significant direct impact on mental elasticity. This exploration aims to conduct a micro investigation on the relationship among the three core variables in the resilience research of children in plight, and analyze their resilience, to provide a theoretical basis for the resilience intervention design of vulnerable groups.

Narrative is increasingly being recognised as an important tool both to manage and understand organisations. In particular, narrative is recognised to have an important influence on the perception of environmental issues in business, a particularly contested area of modern management. Management literature is, however, only beginning to develop a framework for evaluating the quality and legitimacy of narratives. Due to the highly fluid nature of narratives, the traditional notion of truth as reflecting ' objective reality' is not useful here. (...) In this article, an alternative approach that evaluates a narrative in two stages is developed. First, a horizontal reading investigates the surface of the narrative, its textual features, instrumental devices and its integrity as a text, to assess the quality of a narrative. Second, a more philosophical or vertical reading makes explicit the underlying value assumptions that author and reader bring to the writing and reading of the narrative to assess the narrative's claim to legitimacy. The framework is then tested against a narrative on the relationship between business and environment as espoused by a supply chain manager of a UK-based manufacturing company. (shrink)

Until the late 19th century scientists almost always assumed that the world could be described as a rule-based and hence deterministic system or as a set of such systems. The assumption is maintained in many 20th century theories although it has also been doubted because of the breakthrough of statistical theories in thermodynamics (Boltzmann and Gibbs) and other fields, unsolved questions in quantum mechanics as well as several theories forwarded within the social sciences. Until recently it has furthermore been assumed (...) that a rule-based and deterministic system was also predictable if only the rules were known, but this assumption has now been undermined by modern chaos-theory describing rule-based and deterministic, but unpredictable systems, while catastrophe-theory delivers a set of types describing various kinds of instability and conditions for the stability of a given system. Hence the main trait in the theoretical development in the 20th-century science can be described as a basic modification and limitation of some of the fundamental and strong assumptions forwarded in the previous epochs of modern science. Ironically, the very same process has been a process in which the human capacity to intervene in nature has expanded dramatically and mainly with the help of the very same theories, and not least because they allow nature to be described and made manipulable on a lower level and a more fine-grained scale. While the overall theoretical consistency between the various theories has gone, the reach of human intervention in nature has increased based on quite new dimensions whether in the area of physics (e.g.: energy technologies, chemical technologies, nanotechnologies etc.) or biology (ge¬netic manipulation) or in the area of psychology, sociology and culture (artificial simulations of mental processes, new means of communication, implying changes in the social infrastructure and cultural behaviour etc.). While some of these changes and new conditions can be reflected from within the conceptual framework of rule-based systems, albeit more complex than formerly recognized, others seem to give rise to the question of whether there are »systems« and relations between different systems in the world which are not rule-based? For instance, it seems to be obvious that the notion of instability represents a major conceptual break with former theories of rule-based systems, as the stability of the latter is an axiomatically given property implied in the very notion of rule-based systems, while instability can only be the result of external influence which should be explained as the result of another rule-based sy¬stem. While there are no difficulties implied concerning the stability of rule-based systems, the notion of unstable states of a system raises the question of how there can be a system at all if there are no invariant stabilising principles? This is the first question which I will address. And I shall do so by taking two examples of such systems as my point of departure. The first example will be the computer and the second will be ordinary language. In both cases I will argue that the stability of these systems (which are both defined by the existence/presence of human intentions) are provided by the help of - differently organised - redundancy functions which both allow the maintenance of systems in unstable macro-states, suspension of previous rules, underdetermination and overdetermination and generation/emergence/creation of new rules more or less independent of previous rules by the help of optional recursions to the permanently accessible underlying levels as for instance the level of binary representation in computers. Since the notion of redundancy is both controversial as such and often avoided, the concept is discussed (as defined in Claude Shannon's mathematical theory of information and in the semiotic framework of J. J. Greimas) and leading to a more general definition in which the redundancy functions serve to overcome noisy conditions, but at the cost of rule-based stability, determination, and predictability. A second question will be how the notion of rule-generating systems relates to the notion of anticipatory systems and it will be argued that rule-generating systems share some features with an¬ticipatory systems and that the former from a certain viewpoint can be seen as a subclass of the latter, although anticipative features are not necessarily a part of the definition of rule-generating systems. On the other hand, it will be discussed whether anticipatory systems which are not rule-generating systems can exist and it will be argued that the capacity to anticipate is strongly limited if it is not part of a rule-generating system. Therefore, it is concluded that the most powerful anticipatory systems need to be rule-generating systems. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Isaac Barrow on the Mathematization of Nature: Theological Voluntarism and the Rise of Geometrical OpticsAntoni MaletIntroductionIsaac Newton’s Mathematical Principles of Natural Philosophy embodies a strong program of mathematization that departs both from the mechanical philosophy of Cartesian inspiration and from Boyle’s experimental philosophy. The roots of Newton’s mathematization of nature, this paper aims to demonstrate, are to be found in Isaac Barrow’s (1630–77) philosophy of the mathematical (...) sciences.Barrow’s attitude towards natural philosophy evolved from his earnest interest in medicine of around 1650, when a young Cambridge graduate, to natural philosophy (apparently under Henry More’s influence); from his thesis on the insufficiency of the Cartesian hypothesis to geometrical optics and the strong program of mathematization of natural philosophy of the middle 1660s; from Lucasian professor of Mathematics to Chaplain of his Majesty and eminent Restoration divine. Contemporary accounts of Barrow’s life suggest that he grew ever more skeptical about the worth of natural philosophy and mathematics. 1 In his last years he became a prolific [End Page 265] author of sermons and theological works. Published shortly after his death by John Tillotson (1630–94), later archbishop of Canterbury, they occupy over two thousand folio pages. Overloaded with involved philosophical arguments, Barrow’s sermons were apparently not very popular, but they were highly regarded by scholars and the Anglican hierarchy. 2 It is on certain of his sermons, as well as on the philosophical discussions contained in the Mathematical Lectures that our account of Barrow’s philosophy of the mathematical sciences will rest. 3 Barrow’s understanding of the mathematical sciences will allow us to discuss together three issues often analyzed independently: the theological background to English natural philosophy, the changing notion of mixed mathematical sciences during the seventeenth century, and finally the philosophical foundations of modern geometrical optics.It has long been recognized that significant relationships exist between theological voluntarism or intellectualism and views on natural philosophy. In particular Robert Boyle’s theological voluntarism is seen as grounding his experimentalist approach to natural philosophy. It is not quite so clear, however, how well theological voluntarism may relate to a strong program of mathematization such as the one embodied in Newton’s Principia Mathematica. In fact it has been suggested that the relationship is a negative one. This is derived from the necessary character of mathematical laws, which would put unwanted restrictions on God’s absolute dominion over nature, and also from the notion that theological intellectualism is conducive to a deductive, a priori science—the paradigm of which is of course geometry. However, Barrow’s theological voluntarism lead him to heighten the role of mathematics within natural philosophy.During the seventeenth century the so-called mixed or subalternate mathematical sciences changed profoundly. In the Enlightenment mixed mathematics—meaning above all rational mechanics—became one of the most prestigious and influential disciplines. The mixed mathematics of the Enlightenment, however, was markedly different from the Aristotelian [End Page 266] mixed mathematical sciences. The differences are noticeable both in the subject matter and in the substitution of mathematical infinitesimal analysis for geometrical synthesis, but also in the way of grounding mathematical theory on empirical evidence. Barrow’s Mathematical Lectures (delivered at Cambridge from 1664 to 1666) offer a fresh insight into the metamorphosis of these sciences just when Newton’s “mathematical principles” were in the making. Not the least interesting feature of Barrow’s discussion is that God’s omnipotence allows an evaluation of the truth of mathematical theories that do not apply to this world. Therefore, Barrow is led to introduce the distinction between the internal consistency, or mathematical truth, of a mathematical theory and its physical truth. This, in turn, leads him to the notion that theories need testing.Barrow on Matter and GodRecent literature has established significant correlations between theological voluntarism and empiricism, as well as between theological intellectualism and rationalism. As E. B. Davis writes, “the Christian doctrine of creation is a dialogue between God’s unconstrained will, which utterly transcends the bounds of human comprehension, and God’s orderly intellect, which serves as the model for the human mind.” Intellectualist theology considers God’s omniscience His...

The paper attempts to summarize the debate on Kant’s philosophy of geometry and to offer a restricted area of mathematical practice for which Kant’s philosophy would be a reasonable account. Geometrical theories can be characterized using Wittgenstein’s notion of pictorial form . Kant’s philosophy of geometry can be interpreted as a reconstruction of geometry based on one of these forms — the projective form . If this is correct, Kant’s philosophy is a reasonable reconstruction of such theories as (...) projective geometry; and not only as they were practiced in Kant’s time, but also as architects use them today.

We analyze the cognitive strategies underlying performance in the Number task, a Math game that requires both arithmetic fluency and mathematical creativity. In this game all elements in a set of numbers have to be used precisely once to create a target number with basic arithmetic operations. We argue that some instances of this game are NP complete, by showing its relation to the well-known Partition problem. We propose heuristics based on the distinction in forward and (...) backward reasoning. The Number Game is part of Math Garden, a popular online educational platform for practicing and monitoring math skills using innovations in computerized adaptive testing. These educational games generate enormous amounts of rich data on children's cognitive development. We found converging evidence for the use of forward proximity heuristics in the data of Math Garden, consisting of more than 20 million answers to 1,700 items. Item difficulties and the structure of correct answers were analyzed. (shrink)

To investigate the effect of community of inquiry method on improvement of interpersonal relationship skills, based on Matthew Lipman’s theory and practice, an experiment was designed and conducted in Tehran among primary school students of third, fourth and fifth grades. 190 student were randomly selected and assigned to experimental and control group . The experimental group was taught based on community of inquiry methodology for twelve ninety minute sessions. Interpersonal relationship skills were measured by Ardly & Asher’s questionnaire. Results show (...) that means of both experimental and control group on the pre-test didn't have any significant difference. But, the results of pre-test and post-test of both experimental and control group indicated that the mean of post-test scores of experimental group in relation to pre-test in interpersonal relationship skills increased, while the mean of the control group remained the same in the post-test, and the mean of the experimental group in the post-test was higher than the mean of the control group. In order to investigate the persistence of the treatment effect, the students were rechecked after 4 months, and the results appeared to be stable. Therefore, this semi-experimental study has shown that the community of inquiry method has positively affected interpersonal relationship skills in experimental group of children, with effects that continued for at least 4 months after the treatment.

He was huddled against his dog not only for security but warmth. His tiny arm circled Lesha's neck and he looked at me with a mix of curiosity and caution. I knelt and put my hand out for Lesha to smell me. Apparently I didn't pass the smell test. The dog didn't budge from his post. We stood like that for a long time, at the base of the steps to the shelter. I tried the few Russian words I had learned while visiting as a volunteer. The dog didn't understand my broken Russian, or pretended not to, but I managed to get a shy smile from Danil.Alexandra, a nurse volunteer at the shelter, eventually mediated the standoff by giving Lesha, the dog, a cookie. I introduced myself to the little boy. And just like that, he leaned up against me and put both arms around my legs. It didn't matter that I was a stranger, and a stranger who spoke terrible Russian. "Spidey" was an affectionate little guy. He gripped my hand while Alexandra led us up the steps and Lesha followed close behind. Inside was a small room, warm and full of color. One wall was covered in kids' drawings. Another had public health posters in Russian, some with instructions for condom use, others on literacy. There were about fifteen kids in the shelter that afternoon. The young ones were drawing pictures at a low table. Two teenage boys were hunched over a small TV playing a video game. There was only one teenage girl, Irina. She was cooing at the little kid's drawings, showing one girl how to draw a princess. Alexandra said quietly to me, "Most of the teenage girls are only here in the morning. The rest are back at work right now." I found out later "back at work" meant on the streets as sex workers. This city was frequented by businessmen and itinerant workers heading to the factories or lumber mills in the North. The best money for homeless girls was in prostitution. Danil unwrapped himself from me and ran over to the two older boys playing video games. One put his controller down long enough to pull Danil into his lap. The three boys stared intently as Super Mario hopped from mushroom to magic cloud, golden coins spinning above his cartoon head.To the right of the main room was a closet-sized office for the shelter director, Anya, a pediatrician who donated her time to running the shelter for homeless and orphaned youth living on the streets. Alexandra and I stood in the doorway waiting for Anya to finish a phone conversation. Her desk was covered in papers. Behind her were photos of the kids who had "graduated" from the streets. There were cards and letters pinned to a cork board. When [End Page E4] she finished, Anya greeted us with bear hugs and showed us to the clinic area. Next to her office was a small bathroom with a shower and tub. She explained that bath days were on Wednesdays. Around back, with a separate entrance was the small clinic space. The outside metal door had a sliding window that you see at some nightclubs. They ran a needle exchange program out of that door. It was funded for street youth, but from time to time they would get adult addicts. Anya was adamant that this side of the clinic remain separate from the central space for the children. In reality the distance... (shrink)

Efforts to preserve cultural heritage have continuedthroughout history, and currently use game technology. Seriousgames, with their audio-visual features make it possible for players toabsorb and retain the often rather arid data of heritage. Furthermore,such technology facilitates the transmission of heritage globallyamongst remote people, without the need to commute personally.Exploring the literature, we noted a lack of local game culture in Iran,and in the Middle East more broadly. This region is limited in terms ofthe existing global game industry, (...) and the introduction of its culture tothe world depends on the global market. This ascertains the paper'sresearch problem: the need for more local games in the field to promote local historical culture. Hence, the paper aims to preserve anddisseminate the tangible and intangible cultural heritage of its focus area, Iran’s Silk Roads and its caravanserais, by developing and testing a serious game named The Sericum Via. It has a non-linearnarrative, engaging the player in a long journey visiting the Safavidcaravanserais on the Silk Roads, using their detailed information. Thegame's text-based and strategic environment demands decision-making skills throughout the game and is challenging enough to makethe player revisit the game frequently. (shrink)

In the spirit of Von Neumann and Morgenstern (Theory of games and economic behavior, Princeton University Press, Princeton, 1944), we introduce a notion of network stability. We study the structure of stable economic networks and their associated stable payoff allocations by analyzing the conditions under which complete networks and star networks (both with desirable property of inclusiveness) are stable. We also address conditions for existence and uniqueness of stable set of networks.

Problems arise when applying the current procedural conceptualization of decision-making capacity to paediatric healthcare: Its emphasis on content-neutrality and rational cognition as well as its implicit assumption that capacity is an ability that resides within a person jeopardizes children’s position in decision-making. The purpose of the paper is to challenge this dominant account of capacity and provide an alternative for how capacity should be understood in paediatric care. First, the influence of developmental psychologist Jean Piaget upon the notion of (...) capacity is discussed, followed by an examination of Vygostky’s contextualist view on children’s development, which emphasizes social interactions and learning for decision-making capacity. In drawing parallels between autonomy and capacity, substantive approaches to relational autonomy are presented that underline the importance of the content of a decision. The authors then provide a relational reconceptualization of capacity that leads the focus away from the individual to include important social others such as parents and physicians. Within this new approach, the outcome of adults’ decision-making processes is accepted as a guiding factor for a good decision for the child. If the child makes a choice that is not approved by adults, the new conceptualization emphasizes mutual exchange and engagement by both parties. (shrink)

ArgumentRecent studies in Sinology have shown that Qing dynasty editors acted as philologists. This paper argues that the identification of their philological methods and editorial choices suggests that their choices were not totally neutral and may have significantly shaped the way modern historians interpreted specific works edited by mathematicians of that dynasty. A case study of the re-edition in 1798 of a Song dynasty treatise, theYigu yanduan(1259), by a Qing dynasty mathematician will illustrate this point. At the end of the (...) eighteenth century, Li Rui (1773–1817) was asked to prepare an edition of the mathematical works written by Li Ye (1192–1279) for a private collection. Li Rui was a talented mathematician, but he was also a meticulous editor and trained philologist. He adopted his editorial model from the preparation of the imperial encyclopaedia, theSiku quanshu, but Li Rui also made some corrections to the text in an effort to restore an older version of Li Ye's treatises that had been lost. Convinced of the Chinese origin of algebra, Li Rui used philological techniques to recover the lost materials and to restore the roots of “Chinese mathematics.” TheYigu yanduancontains two algebraic procedures to set up quadratic equations, one from the procedure ofCelestial Source(tian yuan shu) and the other from theSection of Pieces[of Areas] (tiao duan). Curiously, the second procedure has not yet attracted the attention of scholars so far, although Li Rui's edition is the one typically used by twentieth-century historians of mathematics. Today, theCelestial Sourcecharacterizes “Chinese algebra.” However, the specific concerns of Li Rui about the procedure ofCelestial Source, combined with his editorial methods, contributed to this perspective.

We propose a new notion of coalitional equilibria, the strong $$\beta$$ -hybrid solution, which is a refinement of the hybrid solution introduced by Zhao. Zhao’s solution is well suited to study situations where people cooperate within coalitions but where coalitions compete with one another. This paper’s solution, as opposed to the hybrid solution, assigns to each coalition a strategy profile that is strongly Pareto optimal. Moreover, like the $$\beta$$ -core, deviations by subcoalitions of any existing coalition are deterred by the (...) threat of a unique counter-strategy available to the non-deviating players. Zhao proved the existence of existence of strong $$\beta$$ -hybrid solution for transferable utility games with compact and convex strategy spaces and concave continuous payoff functions. Here, we extend his result to non-transferable utility games. (shrink)

The Archaeology of Semiotics and the social order of things is edited by George Nash and George Children and brings together 15 thought-provoking chapters from contributors around the world. A sequel to an earlier volume published in 1997, it tackles the problem of understanding how complex communities interact with landscape and shows how the rules concerning landscape constitute a recognised and readable grammar. The mechanisms underlying landscape grammar are both physical and mental, being based in part on the mindset (...) of the individual; the same landscape can thus evoke different meanings for different people and at different times. People's perception has greatly influenced the construction of landscapes over millennia but, until recently, the potential of this area has been largely untapped. Apart from chapters focusing solely upon human interaction with landscape, there are several which skilfully integrate artefacts and place with landscape (e.g. Gheorghiu and Sognnes). Other chapters look at the way people have marked the landscape through such mechanisms as rock-art (e.g. Clegg, Devereux, Estévez, Fossati, Kelleher and Skier). Rock-art establishes personal and communal identity in relation to landscape and it is clear that other forms of visual expression were in place which distinctively created special places within the landscape. Landscape constructs can bind cultures together; bringing the old ways of reading the landscape into contemporary life (e.g. Smiseth). Defining early and late prehistoric landscapes and segregating these into, say, mundane domestic and ritualised spaces rely on both clear and subtle archaeologies and in this volume distinct monument clustering and ritualised linearity are considered (e.g. Mason and Nash). A volume such as this cannot escape the influence of New World approaches, such as anthropology, and in many respects chapters by Bender, Muller and Merritt give context to other chapters within the book. Finally, one must consider text as a means of constructing landscape and this is considered by Heyd, who eloquently deconstructs the travel diary of a 17th century Japanese poet. This will be an important volume for archaeologists, landscape scholars and students. The many approaches used are tried and tested, forming an invaluable resource and not just another edited book.

In this paper, we present a formal interpretive account of Jean Piaget’s theory of the morality that regulates social exchanges, which we call interactional morality. First, we place Piaget’s conception in the context of his epistemological and sociological works. Then, we review the core of that conception: the two types of interactional moralities that Piaget identified to be usual in social exchanges, and the role that the notion of respect-for-the-other plays in their definition. Next, we analyze the main features of (...) social exchanges that are subject to each of those two types of interactional moralities. Following, we formalize Piaget’s account of how the two types of interactional moralities can be put to regulate social exchanges in which values, norms, beliefs, and goals are exchanged, so that interactional commitments can be established among the participants. Then, we sketch a moral reasoning system able to support formal reasonings about interactional moralities. Finally, we illustrate the usefulness of the overall formal model of interactional moralities that resulted from our study by applying it to the explication of some of the conclusions achieved by Piaget in his moral studies about children games.

Abraham Robinson is well-known as the inventor of nonstandard analysis, which uses nonstandard models to give the notions of infinitesimal and infinitely large magnitudes a precise interpretation. Less discussed, although subtle and original–if ultimately flawed–is Robinson's work in the philosophy of mathematics. The foundational position he inherited from David Hilbert undermines not only the use of nonstandard analysis, but also Robinson's considerable corpus of pre-logic contributions to the field in such diverse areas as differential equations and aeronautics. This tension (...) emerges from Robinson's disbelief in the existence of infinite totalities (any mention of them is ‘literally meaningless’) and the fact that much of his work involves them. I argue that he treats infinitary avenues of mathematics as useful tools to avoid this difficulty, but that this is not successful to the extent that these tools must be justified by a conservative extension from finitary mathematics. While Robinson provides a compelling and unorthodox pragmatic justification for the role of formal systems in mathematical practice despite their apparent infinitary presuppositions, he deflates mainstream mathematics to a collection of games that occasionally produces meaningful results. This amounts to giving up on a commitment to reconciling his finitism with his mathematical practice. (shrink)

The aim of the present study was to investigate the effect of the “Visual Awareness Education Programme” developed to support the visual literacy skills of preschool children. The study group comprised 40 children (20 children in the experimental group and 20 children in the control group) attending preschool in the 2014–2015 school year. The pre-test post-test experimental model was used in the study. The “Visual Literacy Inventory for Preschool Children” and the “Children’s Visual Literacy (...) Rating Inventory for Parents” were used to determine visual literacy level of children. Study results revealed significant differences in favour of the experimental group children in the sub-dimensions and the post-test scores of the “Visual Literacy Inventory for Preschool Children” and the post-test scores of the “Children’s Visual Literacy Rating Inventory for Parents”.

The papers collected in this volume exemplify some of the trends in current approaches to logic, language and computation. Written by authors with varied academic backgrounds, the contributions are intended for an interdisciplinary audience. The first part of this volume addresses issues relevant for multi-agent systems: reasoning with incomplete information, reasoning about knowledge and beliefs, and reasoning about games. Proofs as formal objects form the subject of Part II. Topics covered include: contributions on logical frameworks, linear logic, and different approaches (...) to formalized reasoning. Part III focuses on representations and formal methods in linguistic theory, addressing the areas of comparative and temporal expressions, modal subordination, and compositionality. (shrink)

Lack of guidance and regulation for authorizing medical cannabis for conditions involving the health and neurodevelopment of children is ethically problematic as it promulgates access inequities, risk-benefit inconsistencies, and inadequate consent mechanisms. In two virtual sessions using participatory action research and consensus-building methods, we obtained perspectives of stakeholders on ethics and medical cannabis for children and youth. The sessions focused on the scientific and regulatory landscape of medical cannabis, surrogate decision-making and assent, and the social and political culture (...) of medical cannabis. We found that evidence-gathering and data dissemination, pressures on clinical relationships, and the lack of integration of culturally diverse perspectives and Indigenous knowledges were key areas of concern. Participants emphasized the importance of utilizing adaptive study designs, highlighted the importance of trust-building between clinicians, patients and caregivers, and discussed barriers including historical and ongoing stigmatization of medical cannabis. We conclude that continued public consultation and strength-based research that integrate diverse perspectives are critical steps forward. (shrink)

This article explores the notion of pedagogical authority as exercised in the Community of Inquiry, the method for facilitating Philosophy for Children (P4C). It argues that the teachers’ pedagogical authority in a Community of Inquiry is not predicated on their intellectual superiority or status. Rather it finds its legitimacy in their role as instigators of students’ thinking skills, which are assumed to be already possessed by the learners. This thesis is discussed in relation to Rancière’s concept of the dissociation (...) of the will and the intellect, which is treated here as conceptual complement to the existing interpretation of pedagogical authority as understood and practiced by scholars in the field of P4C.

Intensive professional testing of children with disabilities is becoming increasingly prominent within the field of children’s rehabilitation. In this paper we question the high quality ascribed to standardized assessment procedures. We explore testing practices using a hermeneutic-phenomenological approach analyzing data from interviews and participant observations among 20 children with disabilities and their parents. All the participating children have extensive experience from being tested. This study reveals that the practices of testing have certain limitations (...) when confronted with the lived experience of those who are being tested. Testing seems to transmit the experts’ view of what is important, correct and admirable, and the way in which an individual child fulfills such requirements and fits in with the predetermined standard. Regular testing may result in insecurity on the part of the tested individual, and possibly to a lack of confidence in their body and the way it functions. For the individual being tested the meaning of testing is primarily related to passing or not passing the test requirements. Given the meaning of testing, children with disabilities may experience repeated testing as an ordeal that they are expected to put up with. By illuminating the experiences of the ones exposed to testing, this paper offers new insight for professionals to gauge more accurately the quality of contemporary testing practice. (shrink)

Descartes is often identified as having fired one of the opening shots of the scientific revolution: rejecting the four Aristotelian causes in favor of the efficient causes characteristic of mechanistic science. Scholars often write as if Cartesian science and corporeal metaphysics is best understood as a rejection of all causal notions other than the efficient. I argue that this is a mistake. On the contrary, Descartes endorses an avowedly Aristotelian notion of formal causality, inherited from Suárez, and this notion (...) is central to his physics and corporeal metaphysics. -/- I begin by tracing the history of the formal cause from Aristotle to Aquinas and Suárez. My main thesis here is that the Aristotelian notion of formal causation picks out two distinct explanatory modes. The first is linked to hylomorphic ontology, and so by rejecting hylomorphism Descartes rejects one sort of formal causation. Crucially, however, the Aristotelians also identify explanations from essence as a species of formal causality. Now, Descartes’s entire philosophical project is built upon the intellectual perception of the essences of God, mind, and matter; the uncovering and exercise of this broadly Platonic intellectual capacity is, as Descartes explained to Hobbes, a key raison d’être for project of the Meditations. So we might expect Descartes to embrace formal causal explanations from essence, which harmonize so thoroughly with his philosophical project. And indeed, this is what we find. This is most obvious in the case of the ontological argument. In the course of defending the claim that God is causa sui, Descartes explicitly appeals to formal causation and claims to be only be “following in the footsteps” of Aristotle. Thus, there is a Cartesian notion of formal causation that is both continuous with and distinct from its Aristotelian predecessors. -/- Other cases are less obvious, but no less important. For example, one of the most strikingly “modern” aspects of Cartesian physics is its emphasis on quantitative laws. Yet Descartes’s official account of how these laws explain particular phenomena is puzzling: He claims that the laws are causes. This, however, is prima facie absurd; Descartes seems to claim that the law of inertia is literally pushing the moon forward along its orbital path. I argue that this is not and cannot be what Descartes means. On the contrary, he clearly takes the laws of physics to follow from the divine essence, especially immutability and simplicity. The laws are true and epistemically accessible to us because they follow from the divine essence. In other words, Descartes thinks nomological explanation in physics is formal causal explanation from (the divine) essence. -/- Another central issue is the impenetrability, or solidity, of matter. I offer a close reading and reconstruction of Descartes’s argument that matter is necessarily but not essentially impenetrable, and I show how Descartes accounts for impenetrability without compromising his mathematical conception of the corporeal. Descartes argues that impenetrability follows from the nature of matter as geometrical extension, thereby reducing a paradigmatic quality of matter (its solidity) to quantity (extension). Note that the explanatory bite throughout is from essence. Thus, while solidity is not a genuine corporeal causal power, it does give bodies an ineliminable causal role in Cartesian physics and corporeal metaphysics. This role is as a formal cause, since every explanation from impenetrability is ipso facto an explanation from the corporeal essence, geometrical extension. This, in turn, shows that Descartes has a principled response to idealists, like Berkeley, who claim that matter’s lack of efficient causal power implies idealism; Berkeley’s mistake, Descartes would argue, lies in equating efficient causality with causality simpliciter. -/- Thus, I argue that formal causal explanation from essence is both well-attested textually in Descartes and is consonant with some of his deepest projects and commitments, including his Platonic intellectualism and mathematization of the corporeal. All this in mind, it is shocking how little attention has been paid to formal causation in Descartes’s metaphysics. If I am right, a thorough re-thinking of Descartes’s physics and metaphysics is long overdue. (shrink)

Strategic games require reasoning about other people’s and one’s own beliefs or intentions. Although they have clear commonalities with psychological tests of theory of mind, they are not clearly related to theory of mind tests for children between 9 and 10 years of age “Flobbe et al. J Logic Language Inform 17(4):417–442 (2008)”. We studied children’s (5–12 years of age) individual differences in how they played a strategic game by analyzing the strategies that they applied in a (...) zero, first, and second-order reasoning task. For the zero-order task, we found two subgroups with different accuracy levels. For the first-order task, subgroups of children applied different suboptimal strategies or an optimal strategy. For the second-order task only suboptimal strategies were present. Strategy use for all tasks was related to age. The 5- and 6-year old children were additionally tested on theory of mind understanding and executive functioning. Strategy-use in these children was related to working memory, but not to theory of mind after correction for age, verbal ability and general IQ. (shrink)

Lewis was not, and is not, very popular in the academy. I think there are three reasons.First, he did not stick to his subject, which was medieval and Renaissance literature. He wrote highly successful children's books, theological works, and articles accessible to nonspecialists, and was an acclaimed broadcaster. All this allowed his critics to suggest that he was not a proper academic, because proper academics do not throw their nets so wide.Second, he was good at everything he did (except (...) perhaps some areas of philosophy: he was famously bested by Elizabeth Anscombe when he ventured onto her home ground). This was perhaps the most infuriating thing about him. The justification for academic superspecialization is that one cannot do more than one thing really well. But Lewis did. He was a better Renaissance scholar than those who criticized him, moaned about him in the Oxford cloisters, and blackballed him for appointments. He is relentlessly readable; therefore (said his detractors) his scholarship must be shoddy.Lewis infuriates me too. Often, when I think I have had an original thought in some domain a million miles from Renaissance literature, I discover not only that Lewis had had that thought already, but had explicated it, seeing angles I never noticed, and more often than not he had exploded it, using a tenth of the words I used, and all in devastatingly simple prose that would entertain and illuminate the most uninterested plumber.And third, of course, he was a Christian, which was then becoming an unforgivable sin, as it remains now in the humanities (though not the physical sciences or mathematics). The usual (stated) objection to academic Christians is that their theological commitment precludes objectivity, but Lewis's academic writing (notably his English Literature in the Sixteenth Century: Excluding Drama [1954]) was so good that that indictment could not stick, and his opponents descended into incoherent fulmination about superannuated paradigms.These reasons help to explain the chilly reception (or, more often, nonreception) by self-billed “serious thinkers” of Lewis's “space trilogy”: Out of the Silent Planet, Perelandra, and That Hideous Strength (hereafter THS). In relation to THS there is another reason: the novel is about them. No, about us. Lewis's view of us is just too keen, his diagnosis too alarming.The main concerns of THS are dehumanization, the role of institutions in that dehumanization, and the desire of individuals to be part of an esoteric circle. More broadly, it concerns the nature of evil. Its debt to the Divine Comedy and to Charles Williams, Lewis's fellow Inkling, are clear.The central character is a young academic, Mark Studdock. We all know him. His education had been “neither scientific nor classical—merely ‘Modern.’ That left him pathetically manipulable. The severities both of abstraction and of high human tradition had passed him by: and he had neither peasant shrewdness nor aristocratic honour.” Studdock was “a man of straw, a glib examinee in subjects that require no exact knowledge.” He stood for nothing; he weighed nothing.Humans are not supposed to be weightless. We will do anything to convince ourselves that we have mass. Many of our strategies are counterproductive. Some are disastrous and lead to dissolution. Studdock's strategy is one of the commonest and most catastrophic: he tries to get to the center of things—to the “Inner Ring” whose geography is described by Lewis in his 1944 lecture (and later essay) of that name. At some level, at least occasionally, Studdock knows the stupidity of this ambition, but he closes his eyes and his mind. And he begins to be used by forces far greater than any he had dreamed of.The book opens with a merciless (and horribly entertaining) account of academic politics. Read it and cringe in recognition: the mechanics of toadyism; the devices for getting your own way with a committee (put the real business in coded form at the end of an agenda, to be dealt with on a hot day after lunch); infuse everything with an appeal to self-interest, but never put it quite like that, for fear of awakening long-dormant altruism. Obfuscate: do not call the sale of an ancient woodland in which Merlin's body lies “the sale of Bragdon Wood” but the sale of “the area coloured pink on the plan.” Learn to talk like the bursar of Studdock's college, for each of his sentences was “a model of lucidity: and if his hearers found the gist of his whole statement less clear than the parts, that may have been their fault.” As a manual for getting your own way in institutions, The Prince is artless and benign beside THS.Studdock becomes a pawn in a big and diabolical game. A vast organization, the National Institute for Coordinated Experiments, known, of course, as “NICE” (never underestimate the importance of an acronym), which turns out to be the instrument of dark supernatural forces, is becoming a state within a state. It is unaccountable. That is its tagline, indeed: it will be free of the red tape that inhibits the research of more conventional institutions. And who can define with sufficient exactitude the difference in principle between tedious administrative red tape and moral stricture? If you are in with the NICE, anything goes.The NICE's project is the unmaking of everything that is quintessentially human and, eventually, everything that is biological. Life itself is just too unhygienic. Beauty is a joke. Sentiment a delusion. Love merely a result of chemical interactions in the brain. Nothing signifies.The NICE has a handful of opponents—a raggedy bunch (including a bear) under the direction of Ransom, who has traveled outside planet Earth in the previous two books in the trilogy. The company, it turns out, is the remnant of the old Arthurian kingdom of Logres, which has always been in tension, if not war, with the modern kingdom of Britain: “Haven't you noticed that we are two countries? After every Arthur, a Mordred; behind every Milton, a Cromwell: a nation of poets, a nation of shopkeepers: the home of Sidney—and of Cecil Rhodes.” They recruit Studdock's wife, Jane, who can spy clairvoyantly on the NICE, and then a revived Merlin comes from his tomb to their aid.THS is strong meat. Many will balk at its supernaturalism, and perhaps in particular its complementarian view of the relationship between the sexes. But hear Lewis out: you might not agree with him, but he is always interesting. When I read THS thirty years ago, I thought it a ripping yarn. It still is. But now I see it as prescient, prophetic, and profoundly important. It should be on every university reading list, for every subject, and no one should be allowed to hold any kind of public office until they have shown that they have assimilated its lessons.

Throughout history, education has always been essential for humanity's justice and fundamental for the creation of a free and satisfying society with the dissemination of knowledge. Hence, in addition to the life occurrences educating people, traditional higher education methods have played an important role for a long period. However, the age of technology has changed the educational system along with the people's lifestyles to meet the continuously changing conditions. During the past twenty years, the Information and Communication Technologies (ICTs) led (...) to the emergence of e-learning non-traditional educational methods bringing about an innovative dimension of virtual learning. With its beneficial features provided by the Internet and various technologies, this method passes the control of time and location from the tutors to the students during the learning process. Despite the entrance of online education into the students' life many years ago, the Covid-19 outbreak initiated in 2020 turned this method into the only possible way of education for almost two years. Afterward, plenty of studies investigated its effects on students' social and academic life, mostly considering its negative impacts on their mental health and motivation due to interaction issues. They also pointed out the specific problems of tactile learner students in the lack of face-to-face design courses. As an innovative solution able to be adopted, game technologies, increasing immersion of the learner in a real-world skill, and triggering motivation are one of the best methods integrated into educational systems. Known as serious games, these games, adopted by almost any domain, convey educational content along with entertainment, increasing interaction. They train or enhance a certain skill or topic to the player by immersing them. While serious games are more expanded nowadays, they are still not being played by the mass public due to people's immersiveness expectations of a game. Hence, the Head-Mounted Displays (HMDs), with their emergence, increased the players' engagement and immersion with all types of virtual environments in digital games. This technology, however, evolved serious games area most, among others, by enabling the opportunity to provide a riskless and low-cost learning environment for real-world skills. In the process of suggesting serious games as a replacement for the traditional educational methods, the most important factor is being aware of their effectiveness for education. Generally, digital games, one of the world's biggest and fastest-growing industries, rely heavily on the virtual landscape, a major part of its development process. Its design demands remarkable effort, and it directly affects the whole game's characteristics. Hence, serious games, as a type of digital game, carry the same attributes. With the appearance of virtual reality technology, gaming started to gain more immersiveness and engagement with artificial elements and environments. Although virtual landscapes were always being developed since the emergence of digital games, the studies taking virtual landscapes into account are mostly using them as a tool for enhancing real spaces, not as a domain for the sake of its development. While other design domains are applying various design methodologies, it is challenging to find a standard design methodology for the design and production of virtual landscapes in the gaming industry, leading to inconsistent and low-quality results. Hence, it comes to the question of what is the virtual landscapes' role in serious games and their effect on the data comprehension rate. Since the literature lacks regarding the gradual change of the virtual landscape in serious games and the content they transmit, this thesis aims to figure out the gradual chronological evolution of the virtual landscapes in serious games. It also aims to seek how this change and the virtual reality technology invention have affected the contents transmitted by digital games and its influence on the player interaction and learning rate. To do so, in the process of this thesis, we developed, tested, and evaluated various serious games, both text-based and with 360° photos. The steps taken revealed the reluctance of the players to follow the providing educational content and their inadequacy of interaction. Hence, the thesis seeks the reasons ending to this result and the ways of increasing this learning rate. Afterward, the thesis uses a currently available but not massively used digital game classification methodology. This methodology, which is based on the principles of architecture, landscape architecture, and urban planning, classifies the games based on their constituting virtual landscapes. Hence, the thesis considers all Steam games, one of the biggest video game digital distribution services, filtered with the 'education' tag, ending in 2531 digital games. Afterward, adding the 'game' tag the result reduced to 1102 games. Finally, with some manual filterings ignoring the irrelevant content, the final number decreased to 702. Sorting chronologically, we made an Excel database including the games' introductory information, the content they transmit, their release date, if they support HMD or not, and whether they are simulation games or not. Due to Steam's dating spectrum, our database includes games dating back from 1992 to 2020. Afterward, we classified all of these games using the virtual landscape classification methodology and generated their related codes based on their player scale, story, dimension, space shape, and interaction level. Investigating the results, they revealed some growth patterns relating to the content educated in the game, the VR technology, and the virtual landscape evolution. Adding the user reviews of Steam, we reverse engineered five of the best serious games on the database due to the digital game design methodology. This methodology divides the games' virtual environment into five layers, namely, player activity map (PAM), story layer, natural environment layer, virtual environment layer, and media layer. Reverse engineering the five best digital games ever, based on the IGN database, enabled us to compare the outcomes. Due to released data, we understand how the games' assets are distributed within the various layers of the virtual environment in the most successful games. Finally, the thesis aims to provide a framework based on these results for developing serious games to increase player interaction and enhance the learning rate. However, these results can be expanded to any virtual landscape other than only serious games' for their interaction enhancement. Currently, the landscape architecture domain only adopts the virtual landscape area as a tool for enhancing design in the real world. However, in the near future, landscape architects will perform in the virtual landscape area as a domain to be enhanced. Hence, that day, the results of this study will play an important role and will be a roadmap for generating highly interactive virtual landscapes. (shrink)

This article seeks to provide a historically well-informed analysis of an important post-Newtonian area of research in experimental physics between 1798 and 1898, namely the determination of the mean density of the earth and, by the end of the nineteenth century, the gravitational constant. Traditionally, research on these matters is seen as a case of “puzzle solving.” In this article, the author shows that such focus does not do justice to the evidential significance of eighteenth- and nineteenth-century experimental research (...) on the mean density of the earth and the gravitational constant. As Newton’s theory of universal gravitation was mainly based on astronomical observation, it remained to be shown that Newton’s law of universal gravitation did not break down at terrestrial distances. In this context, Cavendish’ experiment and related nineteenth-century experiments played a decisive role, for they provided converging and increasingly stronger evidence for the universality of Newton’s theory of gravitation. More precisely, the author shall argue that, as the accuracy and precision of the experimental apparatuses and the procedures to eliminate external disturbances involved increasingly improved, the empirical support for the universality of Newton’s theory of gravitation improved correspondingly.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.1 (2003) 21-39 [Access article in PDF] Capability and Language in the Novels of Tarjei Vesaas Catherine Wilson I THOUGH RELATIVELY UNKNOWN to English-speaking readers, Tarjei Vesaas (1897-1970) is recognized as one of the great Scandinavian novelists and literary innovators of the last century. His oeuvre is substantial, extending to thirty-four volumes published between 1923 and 1966, many of them translated into English and European languages. (...) He was one of four nominees for the 1964 Nobel Prize in literature, and he received a number of other awards and citations in the course of his life. At the same time, his work has failed almost entirely to generate a secondary literature going beyond plot summary, stylistics, and moral approval, and even that literature remains strongly regionalized. 1 Vesaas wrote in nynorsk or "New Norwegian," the minority language of the country created from south-central dialects and distinct from the official, bureaucratic bokmal. He settled permanently on a farm in the remote Telemark district of Norway and assumed no role in European culture as critic or essayist, refusing to discuss his own work in literary or philosophical terms. As a result, analytic and comparative studies have proved difficult to launch.The present essay is intended to provide one such analytical study, addressed specifically to the philosophical themes of ethical resignation, the precariousness of communication, and inwardness. These are familiar themes in twentieth-century literature. In his study of the "literary conquest of the void," R. M. Adams shows how Moravia, Musil, and Beckett amongst others make use of devices of paralysis, immobility, exhaustion, and incomprehension that have their origins in the romantic literature of the nineteenth century, notably in Baudelaire [End Page 21] and Gogol. 2 Literary modernism rejected certain nineteenth-century conventions of plot and character, but did not abandon the fascination of the preceding century with nihilistic themes. Vesaas's work demands to be read in this literary context. The novels, at once semirealistic and highly stylized, deal almost exclusively with rural people and their struggles against the elemental forces of nature. The main characters are often children and adolescents who suffer some degree of helplessness. Simple contrasts are posed: warmth and cold; loss and retrieval, childbirth and death. Agricultural cycle motifs abound. The choice of protagonists and the dominance of vitalistic and biological themes pose the threat of sentimentality and preciousness, but it is avoided by the ubiquity of devastation and destruction in the moral landscape. According to Randi Brox's note in the Dictionary of Scandinavian Literature, the early novels in particular "advocate as the highest goal in life an accepting, contented attitude toward the human condition." 3This judgment reflects what might be termed a judicial-theological picture of fiction. On this view, a novel constitutes a testing ground for discovering what sort of world we live in and what pursuits are possible and worthwhile. Various alternatives are set up as hypotheses, and novels prove and disprove them through narrative demonstrations of the causal effects of adopting them. False theories of the human world and untenable values are subject to refutation. This template is surprisingly useful, not only with respect to the nineteenth-century novel, with its apparent tendency to confident judgment, but even to modern fiction. Moravia, for example, can be seen to be awarding divergent roles to characters and allowing the qualities they represent to struggle for supremacy. 4Yet poststructuralist and postmodernist criticism have cast doubt on the notion that, to the extent that they are important, such contests can ever be decided, and it is increasingly clear that the greatest nineteenth-century novelists, Hardy and Eliot, did not regard the hierarchy of values as settled and demonstrable. Persons, we are coming to understand, are more plausibly seen as sites of conflict; thus fictional representations of persons are repositories of opposing values. Vesaas's novels reflect such an understanding of persons and values, and so the judicial-theological template is inapplicable.The critical view that Vesaas's novels are essentially instructions in adaptation is untenable, because the goal of...

Recent advances in the technology of creating chimeras have evoked controversy in policy debates. At centre of controversy is the fear that a substantial contribution of human cells or genes in crucial areas of the animal’s body may at some point render the animal more humanlike than any other animals we know today. Authors who have commented on or contributed to policy debates specify that chimeras which would be too humanlike would have an altered moral status and threaten our notion (...) of ‘human dignity’. This setting offers a productive opportunity to test the notion of human dignity and to emphasize some of its weaknesses as an ethical tool. Limiting chimerism experiments on the basis of whether or not it undermines or challenges human dignity implies a clear demarcation of those characteristics which are typically, and importantly, human. Evidence of our evolutionary ties and behavioral similarities with other animals seem to annul all attempts to define the uniquely human properties to which human dignity may be attributed. Hence, it has been suggested that the particular moral status associated with humans cannot be explained for beyond an intuitive basis. In what follows, we will argue that the difficulties inherent in the notion of human dignity lie not in the impossibility to acquire a list of properties which are unique to humans, but rather in the difficulty to demonstrate the moral relevance of these properties, and particularly the relevance of their being human. We offer an alternative interpretation of the concept of dignity which is not necessarily related to being human. (shrink)

It is commonly held that Kant, with his 1798 essay The Conflict of the Faculties, relinquishes some progressive stances and retreats to conservative positions. According to several interpreters, this is especially evident from Kant’s discussion of moral progress and public use of reason. Kant avers that moral progress can only occur through state-sanctioned education “from top to bottom” and entrusts the emergence of a state endowed with the relevant resolution and ability to “a wisdom from above” (7:92-93). According to numerous (...) interpreters, this call for state intervention and the accompanying surrender to a superhuman wisdom manifest Kant’s retreat from initially republican to later conservative positions. In Kant’s previous writings, the notion of public use of reason indicates the unrestricted freedom to communicate one’s thoughts, provided that the communication does not take place in the exercise of one’s function as a state official, and potentially encompasses all adult men. Instead, in The Conflict of the Faculties, Kant contrasts university professors’ freedom to make public use of their reason with the other public officials’ obligation “to uphold whatever […] the crown sanctions for them to expound publicly” (07:08). Thus, according to several scholars, Kant ends up disenfranchising the vast majority of people from the public use of reason and adjusting an emancipatory notion to the absolutist conception of speech and civil service. On my reading, with The Conflict of the Faculties, Kant neither retreats to conservative positions nor softens any progressive tenets of critical philosophy. On the contrary, I intend to show that a) the project of a state-sanctioned education constitutes Kant’s republican rebuttal of conservative positions on their ground, and is fully in keeping with critical philosophy; b) Kant sets forth a new notion of public use of reason that reverses the order of moral progress presented in his previous writings, but retains all its emancipatory character. I intend to support my interpretation by a) conducting a rhetorical analysis showing how Kant’s rhetoric aims to persuade the ruler that his interests are best served by fostering the regulative ideas of pure practical reason as discovered by critical philosophy; b) analysing Kant’s use of the term ‘public’ (both as the adjective ‘öffentlich’ and the noun ‘Publikum’) and showing how it retains its wide scope and emancipatory function and even expands them to areas previously subjected to legitimate censorship.

Although gains in generational intelligence test scores have been widely demonstrated around the world, researchers still do not know what has caused them. The cognitive stimulation and nutritional hypotheses summarize the several diverse potential causes that have been considered. This article analyses data for a sample of 499 children tested in 1930 and one equivalent sample of 710 children tested 72 years later, the largest gap ever considered. Both samples comprised children aged between 7 and 11 who (...) were assessed by the Draw-a-Man test in the city of Belo Horizonte, Brazil. Further, one additional sample of 132 children was assessed in 2004 in a rural area very similar in several diverse factors to the 1930 urban sample. The results are consistent with both the cognitive stimulation and the nutritional hypotheses. (shrink)

Strategic games require reasoning about other people’s and one’s own beliefs or intentions. Although they have clear commonalities with psychological tests of theory of mind, they are not clearly related to theory of mind tests for children between 9 and 10 years of age “Flobbe et al. J Logic Language Inform 17(4):417–442 (2008)”. We studied children’s (5–12 years of age) individual differences in how they played a strategic game by analyzing the strategies that they applied in a (...) zero, first, and second-order reasoning task. For the zero-order task, we found two subgroups with different accuracy levels. For the first-order task, subgroups of children applied different suboptimal strategies or an optimal strategy. For the second-order task only suboptimal strategies were present. Strategy use for all tasks was related to age. The 5- and 6-year old children were additionally tested on theory of mind understanding and executive functioning. Strategy-use in these children was related to working memory, but not to theory of mind after correction for age, verbal ability and general IQ. (shrink)

The capacity to search for information effectively by asking informative questions is crucial for self-directed learning and develops throughout the preschool years and beyond. We tested the hypothesis that explaining observations in a given domain prepares children to ask more informative questions in that domain, and that it does so by promoting the identification of features that apply to multiple objects, thus supporting more effective questions. Across two experiments, 4- to 7-year-old children (N = 168) were prompted to (...) explain observed evidence or to complete a control task prior to a 20-questions game. We found that prior prompts to explain led to a decrease in the number of questions needed to complete the game, but only for older children (ages 6-7). Moreover, we found that effects of explanation manifested as a shift away from questions that targeted single objects. These findings shed light on the development of question asking in childhood and on the role of explanation in learning. (shrink)

: The natural philosopher Michael Faraday and the psychologist Jean Piaget experimented directly with natural phenomena and children. While Faraday originated evidence for spatial fields mediating force interactions, Piaget studied children's cognitive development. This paper treats their experimental processes in parallel, taking as examples Faraday's 1831 investigations of water patterns produced under vibration and Piaget's interactions with his infants as they sought something he hid. I redid parts of Faraday's vibrating fluid activities and Piaget's hiding games. (...) Like theirs, my experiences showed that incomplete observations and confusions accompanied—and facilitated —experimental developments. While working with things in their hands, these experimenters' minds were also engaged, inferring new, more coherent understandings of the behaviors under study. Transitory ripples disclosed distinct patterns; infants devised more productive search methods. From the ripples, Faraday discerned an oscillatory condition that informed his subsequent speculations about light. From the infant search, Piaget identified experimenting as a child's means of developing self and world, later envisioning its infusion into education. Taken together, these two stories demonstrate that cognitive capacities emerge in the actual process of experimenting. This finding eclipses the historical context in its implications for education today. When learners pursue their own experiments, their minds develop. (shrink)

It is well-established that the experience of nature produces an array of positive benefits to mental well-being. Much less is known about the specific attributes of green space which produce these effects. In the absence of translational research that links theory with application, it is challenging to design urban green space for its greatest restorative potential. This translational research provides a method for identifying which specific physical attributes of an environmental setting are most likely to influence preference and restoration responses. (...) Attribute identification was based on a triangulation process invoking environmental psychology and aesthetics theories, principles of design founded in mathematics and aesthetics, and empirical research on the role of specific physical attributes of the environment in preference or restoration responses. From this integration emerged a list of physical attributes defining aspects of spatial structure and environmental content found to be most relevant to the perceptions involved with preference and restoration. The physical attribute list offers a starting point for deciphering which scene stimuli dominate or collaborate in preference and restoration responses. To support this, functional definitions and metrics—efficient methods for attribute quantification are presented. Use of these research products and the process for defining place-based metrics can provide (a) greater control in the selection and interpretation of the scenes/images used in tests of preference and restoration and (b) an expanded evidence base for well-being designers of the built environment.

Why do people stay together in monogamous relationships? Love? Fear? Habit? Ethics? Integrity? Desperation? In this paper I will consider a rather surprising answer that comes from mathematics. It turns out that cooperative behaviour, such as mutually-faithful marriages, can be given a firm basis in a mathematical theory known as game theory. I will suggest that faithfulness in relationships is fully accounted for by narrow self interest in the appropriate game theory setting. This is a surprising answer (...) because faithful behaviour is usually thought to involve love, ethics, and caring about the well being of your partner. It seems that the game-theory account of faithfulness has no need for such romantic notions. I will consider the philosophical upshot of the game-theoretic answer and see if it really does deliver what is required. Does the game-theoretic answer miss what is important about faithful relationships or does it help us get to the heart of the matter? Before we start looking at lasting, faithful relationships, though, let’s get a feel for how mathematics might be employed to help in matters of the heart. Let’s first consider how mathematics might shed light on dating to find a suitable partner. (shrink)

With the increasing urbanization in China, the mental health problems of migrant children have attracted widespread attention. From the perspective of social cognition, psychological capital, self-esteem, and other factors are closely related to the social and cultural adaptation of the group. In order to explore the relationship among the psychological capital, self-esteem and socio-cultural adaptations of migrant children, a total of 245 Chinese migrant children were investigated with the psychological capital scale, self-esteem scale, and socio-cultural adaptation scale. (...) At the same time, 24 months group longitudinal intervention exercises was designed scientifically, the participants were provided with it continuously to enhance their psychological capital. According to the results, there were significant differences in t-test in experiment group and control group of migrant children. At the same time, there was a significant linear correlation between predictive variables’ psychological capital and self-esteem and outcome variable’s socio-cultural adaptation. In the next step of mediating effect analysis, psychological capital and self-esteem were adopted for predicting socio-cultural adaptation. The psychological capital could not only directly affect the social and cultural adaptation of migrant children, but also indirectly affect the degree of social and cultural adaptation of migrant children through changing self-esteem. The results showed that the self-esteem mediation model fitted well with the data. Furthermore, the mediation effect accounted for 17.3% in the direct effect. Longitudinal group intervention could improve the psychological capital and social and cultural adaptation of migrant children. In a word, the research was helpful to explore the influence mechanism of migrant children’s psychological capital on social and cultural adaptation, and had certain practical value in preventing and reducing the crisis caused by the social and cultural adaptation of migrant children.

IT IS WELL KNOWN THAT LEIBNIZ’S NOTION OF HARMONY plays a crucial role in his philosophical system. Leibniz drew on this concept of harmony in motivating, and explaining, numerous areas of his thought: everything from Leibnizian mathematics and metaphysics to ethics and social philosophy, incorporates the notion of harmony as a central descriptive and explanatory concept. While there has been much discussion of some the applications of harmony in Leibniz’s system– especially the mind-body harmony, and the so-called universal harmony of (...) simple perceiving substances–little attention has been paid to Leibniz’s very concept of harmony. Yet it seems important for understanding Leibniz’s holistic philosophy that we grasp this concept, for he employed the term “harmony” when describing so many features of the created world: there is a harmony between geometry and physics, between efficient and final causation, between nature and grace, to mention just a few.

Non-Invasive Prenatal Testing is a technology which provides information about fetal genetic characteristics very early in pregnancy by examining fetal DNA obtained from a sample of maternal blood. NIPT is a morally complex technology that has advanced quickly to market with a strong push from industry developers, leaving many areas of uncertainty still to be resolved, and creating a strong need for health policy that reflects women’s social and ethical values. We approach the need for ethical policy-making by studying (...) the use of NIPT and emerging policy in the province of Ontario, Canada. Using an adapted version of constructivist grounded theory, we conducted interviews with 38 women who have had personal experiences with NIPT. We used an iterative process of data collection and analysis and a staged coding strategy to conduct a descriptive analysis of ethics issues identified implicitly and explicitly by women who have been affected by this technology. The findings of this paper focus on current ethical issues for women seeking NIPT, including place in the prenatal pathway, health care provider counselling about the test, industry influence on the diffusion of NIPT, consequences of availability of test results. Other issues gain relevance in the context of future policy decisions regarding NIPT, including funding of NIPT and principles that may govern the expansion of the scope of NIPT. These findings are not an exhaustive list of all the potential ethical issues related to NIPT, but rather a representation of the issues which concern women who have personal experience with this test. Women who have had personal experience with NIPT have concerns and priorities which sometimes contrast dramatically with the theoretical ethics literature. These findings suggest the importance of engaging patients in ethical deliberation about morally complex technologies, and point to the need for more deliberative patient engagement work in this area.
