This paper reviews current psychological theories of syllogistic inference and establishes that despite their various merits they all contain deficiencies as theories of performance. It presents the results of two experiments, one using syllogisms and the other using three-term series problems, designed to elucidate how the arrangement of terms within the premises affects performance. These data are used in the construction of a theory based on the hypothesis that reasoners construct mental models of the premises, formulate informative conclusions about the (...) relations in the model, and search for alternative models that are counterexamples to these conclusions. This theory, which has been implemented in several computer programs, predicts that two principal factors should affect performance: the figure of the premises, and the number of models that they call for. These predictions were confirmed by a third experiment. Dans cet article sont passées en revue les théories psychologiques du traitement des syllogismes. On établit qu'en dépit de leurs mérites variés toutes sont en défaut en tant que théories de la performance. On présente les résultats de deux expériences, une utilisant des syllogismes et l'autre des problémes avec des séries de trois termes conçues pour élucider comment l'arrangement des termes dans les premises affecte la performance. Ces données sont utilisées pour construire une théorie fondée sur l'hypothése que les gens construisent des modèles mentaux des premises, formulent des conclusions explicites sur les relations dans le modèle et cherchent des modèles qui seraient des contre-exemples pour leurs conclusions. Cette théorie, utilisée dans plusieurs programmes d'ordinateur, prédit que deux principaux facteurs affectent la performance: la figure des premises et le nombre de; modèles qu'ils mettent en jeu. Cette prédiction est confirmée dans les trois expériences. (shrink)

One of the most debated questions in psychology and cognitive science is the nature and the functioning of the mental processes involved in deductive reasoning. However, all existing theories refer to a specific deductive domain, like syllogistic, propositional or relational reasoning.Our goal is to unify the main types of deductive reasoning into a single set of basic procedures. In particular, we bring together the microtheories developed from a mental models perspective in a single theory, for which we provide a formal (...) foundation. We validate the theory through a computational model (UNICORE) which allows fine‐grained predictions of subjects' performance in different reasoning domains.The performance of the model is tested against the performance of experimental subjects—as reported in the relevant literature—in the three areas of syllogistic, relational and propositional reasoning. The computational model proves to be a satisfactory artificial subject, reproducing both correct and erroneous performance of the human subjects. Moreover, we introduce a developmental trend in the program, in order to simulate the performance of subjects of different ages, ranging from children (3–6) to adolescents (8–12) to adults (>21). The simulation model performs similarly to the subjects of different ages.Our conclusion is that the validity of the mental model approach is confirmed for the deductive reasoning domain, and that it is possible to devise a unique mechanism able to deal with the specific subareas. The proposed computational model (UNICORE) represents such a unifying structure. (shrink)

The aim of the present study was to investigate the effects of communicative intention on action. In Experiment 1 participants were requested to reach towards an object, grasp it, and either simply lift it or lift it with the intent to communicate a meaning to a partner . Movement kinematics were recorded using a three-dimensional motion analysis system. The results indicate that kinematics was sensitive to communicative intention. Although the to-be-grasped object remained the same, movements performed for the ‘communicative’ condition (...) were characterized by a kinematic pattern which differed from those obtained for the ‘individual’ condition. These findings were confirmed in a subsequent experiment in which the communicative condition was compared to a control condition, in which the communicative exchange was prevented. Results are discussed in terms of cognitive pragmatics and current knowledge on how social behavior shapes action kinematics. (shrink)

Theory of Mind(ToM) is a neurocognitive system that allows the perceiver to attribute mental states, such as intentions, beliefs, or feelings, to others’ actions. The aim of the present work is to analyse the engagement of the ToM system in communication, in particular, in communicative intention processing. To this aim, we propose anIntention Processing Network(IPN) with its own principles and mechanisms, that is, a brain network differentially engaged according to the complex intertwining of the context, goal, and action involved. According (...) to our IPN model, a set of brain regions of the ToM system (i.e. left and right temporoparietal junction, precuneus, and medial prefrontal cortex) are differentially involved in comprehending different types of intention, such as private or social intentions. We provide independent and convergent evidence on the role of the IPN model in communicative intention processing and we show that the engagement of the IPN does not depend upon the communicative means used, that is, written language, auditory language, or gesture. Evidence deriving from different experimental paradigms, including neuroimaging, lesion, neurodegenerative, and brain stimulation studies are discussed. In our view, this evidence establishes a link between ToM and pragmatics studies and suggests the role of intention processing as a core feature of human communication. (shrink)

In this article we present the bases for a computational theory of the cognitive processes underlying human communication. The core of the article is devoted to the analysis of the phases in which the process of comprehension of a communicative act can be logically divided: (1) literal meaning, where the reconstruction of the mental states literally expressed by the actor takes place: (2) speaker's meaning, where the partner reconstructs the communicative intentions of the actor; (3) communicative effect, where the partner (...) possibly modifies his own beliefs and intentions; (4) reaction, where the intentions for the generation of the response are produced; and (5) response, where an overt response is constructed. The model appears to be compatible with relevant facts about human behavior. Our hypothesis is that, through communication, an actor tries to exploit the motivational structures of a partner so that the desired goal is generated. A second point is that social behavior requires that cooperation be maintained at some level. In the case of communication, cooperation is, in general, pursued even when the partner does not adhere to the actor's goals, and therefore no cooperation occurs at the behavioral level. This important distinction is reflected in the two kinds of game we introduce to account for communication. The main concept implied in communication is that two agents overtly reach a situation of shared mental states. Our model deals with sharedness through two primitives: shared beliefs and communicative intentions. (shrink)

Because of the growing debate concerning the nature of Soviet-type societies, a symposium-review was organized around two important recent books on the subject. The following are discussions of either one or both of the following volumes: Ferenc Feher, Agnes Heller, Gyorgy Markus, Dictatorship over Needs, St. Martin's Press (New York, 1983). Victor Zaslavsky, The Neo-Stalinist State: Class, Ethnicity and Consensus in Soviet Society, M.E. Sharpe, Inc. (New York, 1982). In social analysis, effective explanations alternate “thick description” with “thin description” Zaslavsky's (...) The Neo-Stalinist State and Feher's, Heller's and Markus’ Dictatorship over Needs, can be seen to track “actually existine socialism” down the respective paths of “thick” and “think” analysis.

In this paper we present theoretical and experimental evidence for a set of mechanisms by which intention is understood. We propose that three basic aspects are involved in the understanding of intention. The first aspect to consider is intention recognition, i.e., the process by which we recognize other people’s intentions, distinguishing among different types. The second aspect concerns the attribution of intention to its author: the existence of shared neural representations provides a parsimonious explanation of how we recognize other people’s (...) intentions , but in and of itself, is not sufficient to determine who the agent is. Once the intention has been recognized and attributed to an agent, the reasons for, and the aim of, the intention are to be considered. Hence, the third aspect concerns the aim-intention motivating the execution of a certain action. We discuss the neural basis of these three theoretical aspects suggesting a conceptual synthesis.

In this paper we deal with two types of reasoning: induction, and deduction First, we present a unified computational model of deductive reasoning through models, where deduction occurs in five phases: Construction, Integration, Conclusion, Falsification, and Response. Second, we make an attempt, to analyze induction through the same phases. Our aim is an explorative evaluation of the mental processes possibly shared by deductive and inductive reasoning.

While establishing the first type of relevancy, one takes into account the standard issues of the classical philosophy of nature. In particular, they are focused on the question of hylomorphism, evolutionism and miraculous events. This type of relevancy is defined through the relationships between the results of the natural sciences. They imply philosophical problems, a fact that enables us to establish the relationships between these sciences and theology. As a rule, it is the philosophy of nature and philosophy of God (...) (I. G. Barbour, A. Anderwald) that play the role of mediators between the natural sciences and theology. The problems in question continue the relationships between evolution and creation, between science and religion, or religious faith, and between theology and the natural sciences. A discussion on the second type of relevancy depends to a large extent on the aspectual additional definitions of its terms. Obviously, they contain the concepts of science, philosophy, worldview, ideology, religion, and theology. These explicative manoeuvres allow us to take advantage of the strategies, introduced beforehand, of establishing the relationship between science and religion. It is essential for our context to construct a coherent image of the world, an image that is characteristic of the philosophy of nature. This image combines some aspects of science, philosophy, including metaphysics, ethics, and theology. (shrink)

The paper has an ordering character with regard to the current discussions on the issue formulated in its title, and it contains of three parts and conclusion. In the first part some standard functions of theoretical constructs have been presented, e.g. laws, hypotheses, and scientific theories. The most representative among them is the projective function (pro- and retro-gnosis) and the explanatory one. In the set of such functions we find also the inferential role, which is presented in the second part (...) of the paper for traditionally comprehended theoretical constructs. The third part focuses on an alternative approach to the theoretical constructs of inference, i.e. inferences that are actually used in research practice. An important role is given to inconclusive forms of inference. Some schemes of heuristic inferences have been given here, a fact that does not belittle the role of formal logic in the theory of reasonings that occur in science. The methodological position presented in the paper is clearly combined with the epistemological version of scientific realism. (shrink)

The article attempts to provide a brief account of the ways in which lawyers carry through their arguments concerning some closed moral evaluations or norms and showing how by reference to those norms and evaluations they argue some legal issues as, e.g., the question of the interpretation of legal norms. The author based his reasoning on examples taken from Polish legal literature.

The first part of the paper is a reminder of fundamental results connected with the adequacy problem for sentential logics with respect to matrix semantics. One of the main notions associated with the problem, namely that of the degree of complexity of a sentential logic, is elucidated by a couple of examples in the second part of the paper. E.g., it is shown that the minimal logic of Johansson and some of its extensions have degree of complexity 2. This is (...) the first example of an exact estimation of the degree of natural complex logics, i.e. logics whose deducibility relation cannot be represented by a single matrix. The remaining examples of complex logics are more artificial, having been constructed for the purpose of checking some theoretical possibilities. (shrink)

BackgroundTo determine whether the public and scientists consider common arguments in support of animal research convincing.MethodsAfter validation, the survey was sent to samples of public, Amazon Mechanical Turk, a Canadian city festival and children’s hospital), medical students, and scientists. We presented questions about common arguments to justify the moral permissibility of AR. Responses were compared using Chi-square with Bonferonni correction.ResultsThere were 1220 public [SSI, n = 586; AMT, n = 439; Festival, n = 195; Hospital n = 107], 194/331 medical (...) student, and 19/319 scientist [too few to report] responses. Most public respondents were <45 years, had some College/University education, and had never done AR. Most public and medical student respondents considered ‘benefits arguments’ sufficient to justify AR; however, most acknowledged that counterarguments suggesting alternative research methods may be available, or that it is unclear why the same ‘benefits arguments’ do not apply to using humans in research, significantly weakened ‘benefits arguments’. Almost all were not convinced of the moral permissibility of AR by ‘characteristics of non-human-animals arguments’, including that non-human-animals are not sentient, or are property. Most were not convinced of the moral permissibility of AR by ‘human exceptionalism’ arguments, including that humans have more advanced mental abilities, are of a special ‘kind’, can enter social contracts, or face a ‘lifeboat situation’. Counterarguments explained much of this, including that not all humans have these more advanced abilities [‘argument from species overlap’], and that the notion of ‘kind’ is arbitrary [e.g., why are we not of the ‘kind’ ‘sentient-animal’ or ‘subject-of-a-life’?]. Medical students were more supportive of AR at the end of the survey.ConclusionsResponses suggest that support for AR may not be based on cogent philosophical rationales, and more open debate is warranted.

When debating the need for prophets, Muslim theologians frequently cited an objection from a group called the Barāhima - either a prophet conveys what is in accordance with reason, so they would be superfluous, or a prophet conveys what is contrary to reason, so they would be rejected. The Barāhima did not recognise prophecy or revelation, because they claimed that reason alone could guide them on the right path. But who were these Barāhima exactly? Were they Brahmans, as their title (...) would suggest? And how did they become associated with this highly incisive objection to prophecy? This book traces the genealogy of the Barāhima and explores their profound impact on the evolution of Islamic theology. It also charts the pivotal role that the Kitāb al-Zumurrud played in disseminating the Barāhima's critiques and in facilitating an epistemological turn in the wider discourse on prophecy (nubuwwa). When faced with the Barāhima, theologians were not only pressed to explain why rational agents required the input of revelation, but to also identify an epistemic gap that only a prophet could fill. A debate about whether humans required prophets thus evolved into a debate about what humans could and could not know by their own means. (shrink)

In this paper being a sequel to our [1] the logic with semi-negation is chosen as an example to elucidate some basic notions of the semantics for sentential calculi. E.g., there are shown some links between the Post number and the degree of complexity of a sentential logic, and it is proved that the degree of complexity of the sentential logic with semi-negation is 20. This is the first known example of a logic with such a degree of complexity. The (...) results of the final part of the paper cast a new light on the scope of the Kripke-style semantics in comparison to the matrix semantics. (shrink)

The aim of this note is to give an example of application of model theory to the theory of logical matrices. . More precisely, we show that Wojtylak's representation theorem is an immediate consequence of a result due to Mal'cev . Throughout the present note we assume that matrices, and classes of matrices under consideration are of the same xed similarity type. Suppose that K is an arbitrary class of matrices, and M is a matrix . We say that M1 (...) 2 K is called a replica of M in the class K i there is a homomorphism h of M onto M1 such that for every homomorphism g of M into arbitrary N 2 K there exists a homomorphism f of M1 into N such that g = f h.

Tony Harrison’s poetry is rooted in the experience of a man who came out of the working class of Leeds and who, avowedly, became a poet and a stranger to his own community. As Harrison duly noted in one interview, from the moment he began his formal education at Leeds Grammar School, he has never felt fully at home in either the world of literature or the world of his working class background, preferring to continually transgress their boundaries and be (...) subject to perpetual change. The paper examines the relation between poetic identity, whose ongoing construction remains one of the most persistently reoccurring themes of Harrison’s work, and the liminal position occupied by the speaker of Harrison’s verse. In the context of the sociological thought of such scholars as Zygmunt Bauman and Stuart Hall, the following paper discusses the way in which the idea of being in-between operates in “On Not Being Milton,” an initial poem from Harrison’s widely acclaimed sonnet sequence The School of Eloquence, whose unique character stems partly from the fact that it constitutes an ongoing poetic project which has continued from 1978 onwards, reflecting the social and cultural changes of contemporary Britain.

Zygmunt Bauman’s sociology has often been seen as a bleak worldview; he has been called the ‘sociologist of misery’. This article argues that assigning pessimism and misery to Bauman’s work relies on a reading which does not fully consider his sociology of morality. When this is accounted for, Bauman can be seen to have a very optimistic worldview. The significance of such an observation rests on where Bauman’s optimism lies—namely in the hands of inevitably moral individuals who can acquiesce (...) to, reject or modify the demands of liquid modernity. This article argues, with reference to G.H. Mead’s concept of the ‘genius’, that this is where the potential for agency lies in Bauman’s conception of liquid modernity. This is given a political dimension by both Mead and Bauman’s advocacy of democratic forms to help realise this agency. Democracy operates as a ‘societal’ form of morality which builds upon Bauman’s ‘pre-societal’ discussion. (shrink)

Main task of the paper is to recall sociologist and philosopher – Zygmunt Bauman’s observations and concepts on the fears, anxieties, and uncertainties that appear in the modern world. Main focus was directed to Europe as Bauman was particularly concerned about its future and its role in the global society. The paper is illustrated using current examples from political, social, and economic life to confirm and/or negate Bauman’s concepts. We ask: are fears stable or changeable? Are they stronger or (...) weaker? Are they constant, coming to an end, or are they replaced by new ones? Additionally, we confront Bauman’s concepts with the ideas of other sociologists who applied the interpretative perspective. We define fear following Bauman’s various proposals, and we distinguish many kinds of fears, giving examples from Western societies and socio-economic realities during the time of globalization. We refer to a few relevant sociological concepts to understand Bauman’s view better, e.g. the strategy of detour or the term of generalized other. In conclusions, we state that most fears remain the same (especially ontological ones). However, in the 21st century, we can observe the emergence of new ones (also artificial ones). (shrink)

In this article, I offer a literary-critical reading of Modernity and the Holocaust, arguing that Bauman’s non-Hobbesian ethics is linked to a form of Orphic authorship. I contextualize this reading with a study of three literary authors: W.G. Sebald, Peter Weiss and Janina Bauman, and their respective versions of this post-Holocaust authorship. At stake is the drama of the forbidden gaze, the moment when Orpheus turns to look at Eurydice, killing her a second time. Using Levinas’ ethics and his scenario (...) of recognition, Bauman re-writes this fateful gaze as a loving gaze, implicitly proposing a counter-model to the Schmittian gaze — always ready to recognize the enemy, always ready to kill.

What is the best way to understand the narratives of self-identity at the beginning of the 21st century? This interdisciplinary collection brings together perspectives from analytical psychology, sociology, psychiatry, psychosocial studies and psychoanalysis to consider questions about individuation and freedom in our disconnected world. The contributors discuss the meaning of, and need for, individuation in individualized and liquid societies. The book begins with a comparison of three approaches: C.G. Jung's individuation, Ulrich Beck's individualization, and Zygmunt Bauman's liquidity. This sets (...) the tone for further consideration of topics including guilt, social media, global nomads, and surveillance. Theoretical reflections are enhanced by clinical material, and the book emphasises the connections between sociology and psychoanalysis, offering significant insights into the importance of psychosocial approaches. This timely work will be of great interest to academics and scholars of psychosocial studies, Jungian studies, sociology and politics. (shrink)

According to principles of modal security, evidence undermines a belief only when it calls into question certain purportedly important modal connections between one’s beliefs and the truth (e.g., safety or sensitivity). Justin Clarke-Doane and Dan Baras have advanced such principles with the aim of blocking evolutionary moral debunking arguments. We examine a variety of different principles of modal security, showing that some of these are too strong, failing to accommodate clear cases of undermining, while others are too weak, failing to (...) do their advertised work of blocking evolutionary moral debunking arguments. If there is a security principle that slips between the horns of this dilemma—one that is both viable and debunker-blocking—it remains to be formulated. (shrink)

This book, published in 1986, addresses questions concerned with a central normative principle in contemporary assessments of economic policies and systems. What does 'consumer sovereignty' mean? Is consumer sovereignty an appropriate principle for the optimization and evaluation of the design and performance of economic policies, institutions and systems? If not, what is a more appropriate principle? The author argues that the conception of consumer sovereignty has to be broadened so that it is not limited to the market mechanism but includes (...) environmental, work and social preferences. However, even this version runs into serious difficulties as the principle of consumer sovereignty still relies on too subjectivist a conception of the interests of individuals to be suitable for the evaluation of economic institutions. An alternative basis for such evaluation is 'human interests' that are not contingent on particular economic systems, After considering various possibilities, a basic-needs approach is proposed and its use in economic evaluation illustrated.
