It is known that the scale, size, form, and content of the world view is beyond calculation, expression and explanation, as it belongs to the world and to Man. Maybe it’s not even right to call it an event. The worldview combines the countless compatibility inherent in both the world and man, and at the same time, it distinguishes mother and child, as close as twins, native beings as far apart as heaven and earth. Worldview is a product of consciousness. (...) It is a system of relationships. An individual understands the world and the environment through worldview. On the other hand, a person is perceived according to his worldview. In the historical approach, the point of view is variable. Its objects are often outdated or rapidly updated. People are often judged according to the “oldness - newness” of their outlook. Since the worldview phenomenon is evaluated with different approaches (concepts of worldview) according to the requirements of the time, it is more deeply understood in relation to a person, especially a professional personality represented by full activity in a certain field. From this point of view, it is important to study the outlook of the genius scientist Lotfi A. Zadeh, who was born in Azerbaijan, benefit from the principles of history and modernity, outlook on life, and worldview. In the article “Worldview concept. History and modernity (in the context of Lotfi A. Zadeh’s world view)” we tried to analyze the world view of the genius scientist of Azerbaijani origin Lotfi A. Zadeh, who lived for 96 years, i.e. almost 1 century, and continued his scientific research. Thus, in the article, we determined the place of the concept of Worldview in History and Modern consciousness, and by comparing the scientifictheoretical aspects of this concept with Lotfi A. Zadeh’s worldview, we obtained new, relevant and important results. (shrink)

From Introduction: In a 1968 article, ‘Probability Measures of Fuzzy Events’, Lotfi Zadeh pro-posed accounts of absolute and conditional probability for fuzzy sets (Zadeh, 1968).

Modelling with Words is an emerging modelling methodology closely related to the paradigm of Computing with Words introduced by Lotfi Zadeh. This book is an authoritative collection of key contributions to the new concept of Modelling with Words. A wide range of issues in systems modelling and analysis is presented, extending from conceptual graphs and fuzzy quantifiers to humanist computing and self-organizing maps. Among the core issues investigated are - balancing predictive accuracy and high level transparency in learning (...) - scaling linguistic algorithms to high-dimensional data problems - integrating linguistic expert knowledge with knowledge derived from data - identifying sound and useful inference rules - integrating fuzzy and probabilistic uncertainty in data modelling.

A utility-based approach to the understanding of vague predicates (VPs) is proposed. It is argued that assignment of truth values to propositions containing VPs entails unjustifiable assumptions of consensus; two models of VP semantics are criticized on this basis: (1) the super-truth theory of Kit Fine (1975), which requires an unlikely consensus on base points; (2) the fuzzy logic of Lotfi Zadeh (1975), on fuzzy truth values of sentences. Pragmatism is held to provide a key: successful behavior justifies (...) a person's knowledge of the content of a VP. Instead of attempting to determine a consensus underlying successful communication, the utility of individual communications is held to rest on sufficient approximation of meanings between people. 3 Figures, 17 References.

Este trabalho tem como objetivo apresentar a ideia de raciocínios aproximados na perspectiva da teoria fuzzy. Para isso, uma reflexão sobre raciocínio é desenvolvida, iniciando se com a teoria das inferências apresentada por Aristóteles, que se preocupou em compreender as relações entre o pensamento, raciocínio e a linguagem; e posteriormente, uma reflexão fundamentada na lógica fuzzy apresentada pelo professor Lotfi Askar Zadeh, que se tornou um instrumento de inferência para tratar de aspectos do raciocínio aproximado do ser humano.

In 1685, in The Art of Discovery, Leibniz set down an extraordinary idea: "The only way to rectify our reasonings is to make them as tangible as those of the Mathematicians, so that we can find our error at a glance, and when there are disputes among persons, we can simply say: Let us calculate [calculemus], without further ado, to see who is right." Calculemus.

When humans are required to perform two or more tasks concurrently, their performance declines as the tasks get closer together in time. Here, we investigated the mechanisms of this cognitive performance decline using a dual-task paradigm in a simulated driving environment, and using drift-diffusion modeling, examined if the two tasks are processed in a serial or a parallel manner. Participants performed a lane change task, along with an image discrimination task. We systematically varied the time difference between the onset of (...) the two tasks and measured its effect on the amount of dual-task interference. Results showed that the reaction times of the two tasks in the dual-task condition were higher than those in the single-task condition. SOA influenced the RTs of both tasks when they were presented second and the RTs of the image discrimination task when it was presented first. Results of drift-diffusion modeling indicated that dual-task performance affects both the rate of evidence accumulation and the delays outside the evidence accumulation period. These results suggest that a hybrid model containing features of both parallel and serial processing best accounts for the results. Next, manipulating the predictability of the order of the two tasks, we showed that in unpredictable conditions, the order of the response to the two tasks changes, causing attenuation in the effect of SOA. Together, our findings suggest higher-level executive functions are involved in managing the resources and controlling the processing of the tasks during dual-task performance in naturalistic settings.

The term fuzzy logic is used in this paper to describe an imprecise logical system, FL, in which the truth-values are fuzzy subsets of the unit interval with linguistic labels such as true, false, not true, very true, quite true, not very true and not very false, etc. The truth-value set, , of FL is assumed to be generated by a context-free grammar, with a semantic rule providing a means of computing the meaning of each linguistic truth-value in as a (...) fuzzy subset of [0, 1].Since is not closed under the operations of negation, conjunction, disjunction and implication, the result of an operation on truth-values in requires, in general, a linguistic approximation by a truth-value in . As a consequence, the truth tables and the rules of inference in fuzzy logic are (i) inexact and (ii) dependent on the meaning associated with the primary truth-value true as well as the modifiers very, quite, more or less, etc. (shrink)

It has been argued that metaphor and emotion processing are tightly linked together. Here we explore whether neuroscientific evidence supports this claim.

Representational transformation is a technique for deepening our understanding of mathematical concepts and facilitating the process of solving mathematical problems. This article suggests that representational transformation can contribute to thought processes in four ways. Firstly, representational transformation helps people employ a wider range of cognitive resources. When one representation of a concept or a problem is transformed into another representation, the sensory-motor resources that are involved in the processing of the base representation are employed to process the target representation. Secondly, (...) representational transformation helps in the process of organizing scattered information into suitable units. This gives structure to various parts of information and makes them much easier to handle. Thirdly, representational transformation helps in the process of suppressing irrelevant information and unnecessary elements of problems. This is a key step in organizing and structuring information. Fourthly, representational transformation helps in the process of discovering general rules and turning them into explicit knowledge. (shrink)

This article suggests an enhancement of the Masek circle model approach usually used to find a trade-off between modeling complexity, algorithm accuracy, and computational time, mainly for embedded systems where the real-time aspect is a high challenge. Moreover, most commercialized systems today frame iris regions by circles. This work led to several novelties: first, in the segmentation process, the corneal reflection removal method based on morphological reconstruction and pixel connectivity was implemented. Second, the picture size reduction was applied according to (...) nearest-neighbor interpolation. Third, the image gradient of the convolved-reduced picture was then generated using four proposed matrices. Fourth, and to reduce the complexity of the traditional method for the detection of the top and lower eyelids, a new method based on the Radon transform and the least squares fitting method was applied. Fifth, eyelashes were detected via the diagonal gradient and thresholding method. Monogenic signal was used in the feature extraction process. Finally, two distance measures were selected as a metric for recognition. Our experimental results using CASIA iris database V3.0 reveal that the proposed method provides a high performance in terms of speed and accuracy. Using dissimilarity modified Hamming distance, the accuracy of iris recognition was improved, with a false acceptance rate equal to 3% and a speed at least eight times as compared with the state of the art.

Avant d'être un simple lieu de la réflexion philosophique, l'esthétique chez Nietzsche est une perspective générale qui oriente l'ensemble de sa philosophie. Il ne s'agit plus à vrai dire d'une esthétique, mais plutôt d'un esthétisme qui se propose d'interpréter le sens de l'être et la question du sens elle-même dans la perspective de l'art. La démarche proposée a pris le choix d'essayer de démontrer que le déploiement de cet esthétisme se fait chez Nietzsche à travers une pensée originale sur le (...) thème de la création. Ce que propose cet esthétisme est exactement une pensée de la création qui prône l'esprit de l'innovation et de l'affirmation."--Page 4 of cover. (shrink)

For meaning normativism to hold, meaning must have a constitutive part which is obligation-producing. I claim in this paper that linguistic communication is such a constitutive part. I try to show this by means of appeal to Davidson’s triangulation thesis. If I am successful, it may fairly be said that “a Davidsonian can rescue the normativity of meaning”.

This study measured hand and head action strengths of eight typical emotional states using an authentic but implicit emotion elicitation task. Participants listened to and then retold five stories in which eight typical emotional states were experienced by the narrators. The number of hand and head gestures that occur naturally while experiencing an emotional state was used as an index to determine the hand and head action strength of that emotional state. Results showed a larger number of head gestures than (...) hand gestures, suggesting that head action strengths of the eight emotional states are stronger than their hand action strengths. These findings are consistent with the data extracted from Lancaster Sensorimotor Norms (LSN), although the two sets of data were gathered in two completely different experimental conditions and in two different languages. Furthermore, our data showed a prototypical directionality effect for the typical emotional states, specifically, happiness, anger and pride were primarily accompanied by upward gestures but downward gestures for sadness and shame; surprise was primarily accompanied by forward gestures but backward gestures for fear and disgust.

Medical practice is practiced morality, and clinical research belongs to normative ethics. The present book elucidates and advances this thesis by: 1. analyzing the structure of medical language, knowledge, and theories; 2. inquiring into the foundations of the clinical encounter; 3. introducing the logic and methodology of clinical decision-making, including artificial intelligence in medicine; 4. suggesting comprehensive theories of organism, life, and psyche; of health, illness, and disease; of etiology, diagnosis, prognosis, prevention, and therapy; and 5. investigating the moral and (...) metaphysical issues central to medical practice and research. Many systems of (classical, modal, non-classical, probability, and fuzzy) logic are introduced and applied. Fuzzy medical deontics, fuzzy medical ontology, fuzzy medical concept formation, fuzzy medical decision-making and biomedicine and many other techniques of fuzzification in medicine are introduced for the first time. -/- .

The question "What is the good life?" is perhaps the most basic question in all of ethics. The four major paradigms of the good life that have been proposed by various philosophers are: (1) hedonism, (2) various forms of desire-satisfactionism, (3) objective value pluralism, and (4) the hybrid theory--i.e., a combination of (1) and (3). In my dissertation, I critique the leading accounts of flourishing (or wellbeing) and defend an objective value pluralistic theory of flourishing that is based on what (...) I call the "Capacities View of Flourishing" (CVF). According to the central evaluative axiom of the CVF, the flourishing of any creature consists in the development and exercise of the capacities that are essential to that kind of creature. While the basic idea behind the CVF has appealed to an impressive list of philosophers from ancient to modern times, the purported explanatory grounds upon which it is based (about what makes a capacity essential to a given kind of creature) has been difficult to explicate. After considering various popular proposals of what it is for a capacity to be essential to a given kind of creature and showing why they are defective in different ways, I propose a novel modal interpretation of the notion of an essential capacity that is immune to the problems of the other popular accounts. According to the modal interpretation of the CVF, the flourishing of a kind of creature K consists in the development and exercise of the capacities that are necessary to K (i.e., that are required for membership in the class K). In the case of human beings more specifically, I argue that there are four basic capacities that are jointly necessary for membership in the class 'human being.' These are the capacity to know (cognition), the capacity to desire (conation), the capacity to feel (feeling), and the capacity to act (agency). And in the last crucial stage of my defense of the modal interpretation of the CVF, I show how four widely recognized objective goods of knowledge, virtue, pleasure, and achievement are the ideal states of the four basic human capacities of cognition, conation, feeling, and agency. I conclude my defense of objective value pluralism by responding to a famous argument against the objectivity of values: the so-called "argument from relativity." In response to this argument, I first show how the objectivity of values is compatible with a moderate form of (non-conventionalist) evaluative relativism that recognizes a plurality of human goods that are not subsumable under a "unitary" true good. I then argue that the hypothesis that there is a plurality of objective human goods is a better inference to the best explanation of the diversity of human values than the hypothesis that there are no objective human goods at all. Lastly, I show why objective value skepticism has absurd implications as it entails that nothing is genuinely good or bad for anyone. The overall conclusion of my dissertation is that of the leading paradigms of the good life, an objective value pluralistic account of flourishing that explains why certain states are good for us by virtue of their being the ideal realization of the capacities that are essential to us is not only deeply appealing, but on closer scrutiny, the most viable theory of flourishing available.

English in Indonesia has foreign language status. Nevertheless, the language is greatly significant to the country due to its numerous regional and global appeals. The current language policy of Indonesia ensures that the language is taught to children from junior high school level. However, as a reflection of a language that has not been prioritised in school curriculum, school leavers largely have limited grasp of the language by the time they enrol into university programmes. This study attempts to highlight institutional (...) practices in student enrolment into and graduation from English programmes. It is also concerned with issues that are perceived to have derived from the policy. Based on interviews with 23 academics from five universities in Central Java, the majority of whom are administrators, policy-related issues of the English language are identified in this paper. Findings include communication skill difficulties faced by English majors and the juxtaposition of state and private universities in terms of student recruitment. The findings are significant in informing stakeholders such as policy makers, administrators, language instructors, and other practitioners about the impact of language policy and planning on practices in higher education institutions in Central Java and in assisting future decision-making processes whereby the consequences are far-reaching.

In a previous paper the concept of disease was fuzzy-logically analyzed and a sketch was given of a prototype resemblance theory of disease (Sadegh-Zadeh (2000). J. Med. Philos., 25:605–38). This theory is outlined in the present paper. It demonstrates what it means to say that the concept of disease is a nonclassical one and, therefore, not amenable to traditional methods of inquiry. The theory undertakes a reconstruction of disease as a category that in contradistinction to traditional views is not (...) based on a set of common features of its members, that is individual diseases, but on a few best examples of the category, called its prototypes, and a similarity relationship such that a human condition is considered a disease if it resembles a prototype. It enables new approaches to resolving many of the stubborn problems associated with the concept of disease. (shrink)

This work was presented at the Research Center for Philosophy of Science of the Ferdowsi University of Mashhad (Iran) – in Aug 2020. --- -/- Briefly, in the first section of this Persian book, first of all, I (Hereafter: the writer) have presented generalities of Aesthetics and an interpretation of aesthetic universality (Hereafter: φ) and it is argued that each definition of art has to admit φ and this is a Kantian, minimalist, and subjective perspective view (some others would incline (...) objective interpretation of φ, but it is beyond the purpose of this work). What’s more, this view could be applied to all definitions of art e.g. Functionalism, Conventionalism, or Hybrid Theories. Additionally, the writer has replied to some objections, those would promote definitions of art without φ, it seems that they could not be successful to refuse φ, since it appears that φ is a premise in every aesthetic judgment. Next, in another section, the writer has written some primary notes on creativity, those have come from contemporary literature of it, and it is argued that there is a relation between creativity and φ. It is also claimed that the relation is the same φ by the creative processes, creative products, and creative persons, both scientifically and philosophically; and so, the relation represents that φ is true. Besides that, the writer has presented some potential objections to the writer’s aspect of the relation and the writer has also replied to those objections. --- -/- In the next section of the book, the writer has applied the φ by creativity to the philosophy of animal-made art, the writer revolutionarily illustrates that first of all, the normativity of the philosophy of animal-made art is prior to the descriptive one. Second of all, φ is principally the criterion to know that animal-made art is impossible. The writer’s position recognizes those other works of animal aesthetics, which means aesthetics of all of the non-human creatures in the earth or cosmos as a new part of environmental aesthetics, is the marginally second order of animal aesthetics. It is owing to the fact that first of all, the question, of whether animal-made art is possible or not, is normative. Second of all, if one does not concern normativity of the question, then one could not get the answer to the nature of it. Next, one could not distinguish between on the one side, the pleasure of drinking water when one’s thirst may cause death, on the other side, the one’s pleasure of listening to music when there is no urgent necessity of it. The fourth argument is that one needs to identify the normativity of animal-made art because one could generalize aesthetic judgments if one sets φ as the basis of it, and then, one identifies that φ is one of the most fundamental bases in Aesthetics. --- -/- The main section of this book is that the writer’s argument -Animal-Made Art Impossibility Argument- is in favor of the impossibility of animal-made art i.e. Functionalist, Conventionalist, or Hybrid Theories of the definitions of animal-made art, also the writer has replied to some possible ideas and objections to the argument. --- -/- Pouya Lotfi Yazdi --- Iran | June 2022.

This study examined the performances of three groups of participants in interpreting metaphors in three different conditions: congruent gesture-prime conditions, opposite gesture-prime conditions, and no-prime conditions. In congruent gesture-prime conditions, each metaphor was preceded by the congruent gestural representation of metaphor schema. In opposite gesture-prime conditions, each metaphor was preceded by the opposite gestural representation of metaphor schema. The results showed that participants of congruent gesture-prime conditions had the best performance in interpreting metaphors, while participants of opposite gesture-prime conditions had (...) the worst performance. It is suggested that metaphor schema is an important part of metaphorical meaning of a metaphor. Therefore, when this part of meaning is activated by a gestural prime, metaphor comprehension is facilitated. Furthermore, when a schema is used to metaphorically describe a concept or an event, that schema and the neural network that represents it become one part of a larger interconnected neural network that represents the meaning of the metaphor. It could mean that the activation of one part of it could facilitate the activation of the whole of the network. Finally, it is emphasized that a gesture that depicts the schema of a metaphor is in fact the embodied realization of that metaphor. (shrink)

Linguistics, in general, is the basic science of all language studies. It is concerned with the nature and structure of language and with the role it plays in human communication. Medical linguistics uses some methods of general linguistics and also creates additional ones. This is motivated by the following practical needs: Computer-aided data record, storage, and retrieval in medical practice and research require that medical data be stored in such a manner that enables their computational processing. However, databases written in (...) natural medical language cannot be easily processed. To enable efficient natural language processing, medical terms and sentences used in them must be made amenable to syntactic and semantic operations by computer programs. Medical linguistics is an ill-defined, interdisciplinary branch of medical informatics and medical information and library sciences concerned with methods and problems of natural language processing in medicine.

The notions of health, illness, and disease are fuzzy-theoretically analyzed. They present themselves as non-Aristotelian concepts violating basic principles of classical logic. A recursive scheme for defining the controversial notion of disease is proposed that also supports a concept of fuzzy disease. A sketch is given of the prototype resemblance theory of disease.

Social representations research is often undertaken by scholars who seek to ‘give voice’ to knowledge that are held by socially disenfranchised individuals and groups. However, this endeavour poses a number of problems in practice, not least because it assumes that the ‘voices’ voiced by individuals and/or groups in social research will be unambiguous and uniform, and unchanged by the research encounter. Despite the growth of attention to the critical potential of social representations theory, there remains a lack of scholarship on (...) the relationship between the theory's emphasis on the relational, or dialogical, nature of social life and the implications of this for critical research. In this article, I argue that the dialogical epistemology from which social representations research must depart incites reflection upon the design of empirical studies, which must equally attend to both ‘Ego’ and ‘Alter’, and the researcher-researched relationship, which may itself be best viewed as an Ego-Alter interaction. I make the case for adopting dialogical epistemology in critical social psychology, and argue that this is essential to undertaking ethical social research. I conclude by suggesting that claims to ‘giving voice’ have little place in critical social psychology in general, and social representations scholarship in particular. (shrink)

Practical Mysticism in Islam and Christianity offers a comparative study of the works of the Sufi-poet Jalal al-Din Rumi (1207-1273) and the practical teachings of the German Dominican, Meister Eckhart (c1260-1327/8). Rumi has remained an influential figure in Islamic mystical discourse since the thirteenth century, while also extending his impact to the Western spiritual arena. However, his ideas have frequently been interpreted within the framework of other mystical, philosophical, or religious systems. Through its novel approach, this book aims to reformulate (...) Rumi's practical mysticism by employing four methodological principles: a) mysticism is a coherent structure with mutual interconnection between its parts; b) the imposition of alien structures to interpret any particular mysticism damages its inward coherency; c) practical mysticism consists of two main parts, namely practices and stages; and d) the proper use of comparative methodology enables a deeper understanding of each juxtaposed system. Eckhart's speculative mysticism, which differs from and enjoys similarities with the love-based mysticism of Rumi, provides a "mirror" that highlights the special features of Rumi's practical mysticism. Such comparison also allows a deeper comprehension of Eckhart's practical thought. Offering a critical examination of practical mysticism, this book is a valuable resource for students and scholars of Islamic studies, comparative mysticism, and the intellectual history of Islam.

Clinical practice is where the clinical encounter and decision-making occur. Thus, it constitutes the focus of medicine. Since the time of Hippocrates, it has been composed of five activities that have come to be known as anamnesis, i.e., history taking or clinical interview, diagnosis, prognosis, therapy, and prevention. These five activities are fundamental features of the healing relationship. The present chapter is devoted to the analysis and discussion of their logical, methodological, and philosophical problems. Usually, the patient expects the physician (...) to be an expert of her specialty devoid of a bad reputation. This constitutes what may be called a good doctor, i.e., one whose clinical decisions are right and good in most cases, at least in as many cases as another expert in the same area also achieves. In what follows, we shall analyze the characteristics and presuppositions of such right and good clinical decisions. To this end, we shall undertake a conceptual analysis of the clinical encounter and its outcomes, in order to develop a theory of clinical practice. Our analysis consists of the following five parts: 9.1 The Clinical Encounter; 9.2 Anamnesis and Diagnosis; 9.3 Prognosis; 9.4 Therapy; 9.5 Prevention. (shrink)

Two common medical-ethical axions, the health-maximizing axiom and the personhood-respecting axiom, are discussed. On the basis of a philosophical analysis of personhood and freedom of the will it is shown that these two axioms are incompatible. The rejection of the first axiom is suggested.
