"Bu araştırmada Meraga Rasathanesi'nin kurucusu Nasîrüddin Tûsî'nin öğrencisi, meşhur alim, matematikçi, astronom ve İşrâkî filozof Kutbüddîn-i Şîrâzî'nin hayatı, eserleri, öğrencileri ile XIII. Yüzyılın son çeyreğinde İlhanlı nüfuzu altında bulunan Selçuklu Türkiye'sindeki faaliyetleri incelenmiştir. Şîrâzî, Sivas'ta kadılık ve Gök Medrese'de müderrislik yapmış, daha sonra İslamı kabul eden ilk İlhanlı hükümdarı Ahmed Tekudar tarafından elçi olarak Memluk sultanı Kalavun'a gönderilmiştir. Siyasi görevleri bununla sınırlı olmayan Şirazî, Argun Han tarafından Yakın-Doğu haritasını çizmekle vazifelendirilmiş, o da bu görevi başarıyla ifa ederek İlhanlı Devletinde önemli (...) bir konuma yükselmiştir. Ancak Şirazî bu siyasî görevleriyle pek anılmamaktadır. Nitekim onun ilim adamı sıfatı daha önde olmuş, siyaseti bazı nedenlerle tercih etmiştir. Şirazî Anadolu'da aklî ilimler sahasında dersler vererek Meraga matematik ve astronomi ekolunun buraya taşınmasını sağlamıştır. Daha sonra Tebriz'e giderek yetiştirmiş olduğu öğrenciler ve telif ettiği eserleriyle Anadolu, İran ve Türkistan coğrafyasında ilmî ve fikrî bir birliktelik oluşturmuştur. Daha sonra Semerkant matematik astronomi okulu mensuplarının Osmanlı ülkesine göçmeleriyle, Şirazî'nin astronomi ve matematik sahasındaki eserleri Osmanlı medreselerinde ders kitabı olarak okutulmuştur."--Back cover.

Starting from logical structures of classical and quantum mechanics we reconstruct the logic of so-called no-signaling theories, where the correlations among subsystems of a composite system are restricted only by a simplest form of causality forbidding an instantaneous communication. Although such theories are, as it seems, irrelevant for the description of physical reality, they are helpful in understanding the relevance of quantum mechanics. The logical structure of each theory has an epistemological flavor, as it is based on analysis of possible (...) results of experiments. In this note we emphasize that not only logical structures of classical, quantum and no-signaling theory may be treated on the same ground but it is also possible to give to all of them a common ontological basis by constructing a “phase space” in all cases. In non-classical cases the phase space is not a set, as in classical theory, but a more general object obtained by means of category theory, but conceptually it plays the same role as the phase space in classical physics.

In this paper, we introduce the concepts of Pythagorean fuzzy valued neutrosophic set (PFVNS) and Pythagorean fuzzy valued neutrosophic (PFVNV) constructed by considering Pythagorean fuzzy values (PFVs) instead of numbers for the degrees of the truth, the indeterminacy and the falsity, which is a new extension of intuitionistic fuzzy valued neutrosophic set (IFVNS). By means of PFVNSs, the degrees of the truth, the indeterminacy and the falsity can be given in Pythagorean fuzzy environment and more sensitive evaluations are made by (...) a decision maker in decision making problems compared to IFVNSs. In other words, such sets enable a decision maker to evaluate the degrees of the truth, the indeterminacy and the falsity as PFVs to model the uncertainty in the evaluations. (shrink)

Comparative study of Sankhya philosophy of Hinduism and the Ayurvedic system of Indic medicine.

It has long been suspected that attentional processes differ between olfaction and the other senses. Here, we test whether voluntary dishabituation, seen, for example, when we re-attend to the ticking of a clock, can occur in olfaction. Participants were seated in an odorized room, where at various intervals they had to evaluate what they could smell. An experimental group had one nostril open and the other closed, except during the evaluations, so that the closed side was subject to centrally driven (...) habituation, but not peripheral adaptation. A control group had both nostrils closed except during evaluations. Following exposure, the experimental group could not report the room's odor in either the centrally habituated nostril or the nostril that remained open, while the control group could. This effect could result from a number of causes, including olfaction's unique neuroanatomy, functional constraints imposed by detecting volatile chemicals, and as a consequence of limited cortical resources, with implications for the functional value of consciousness.

According to the expertise defense, practitioners of the method of cases need not worry about findings that ordinary people’s philosophical intuitions depend on epistemically irrelevant factors. This is because, honed by years of training, the intuitions of professional philosophers likely surpass those of the folk. To investigate this, we conducted a controlled longitudinal study of a broad range of intuitions in undergraduate students of philosophy (n = 226), whose case judgments we sampled after each semester throughout their studies. Under the (...) assumption, made by proponents of the expertise defense, that formal training in philosophy gives rise to the kind of expertise that accounts for changes in the students’ responses to philosophically puzzling cases, our data suggest that the acquired cognitive skills only affect single case judgments at a time. There does not seem to exist either a general expertise that informs case judgments in all areas of philosophy, or an expertise specific to particular subfields. In fact, we argue that available evidence, including the results of cross-sectional research, is best explained in terms of differences in adopted beliefs about specific cases, rather than acquired cognitive skills. We also investigated whether individuals who choose to study philosophy have atypical intuitions compared to the general population and whether students whose intuitions are at odds with textbook consensus are more likely than others to drop out of the philosophy program.

Göçmenlerin farklı kimliklere sahip olmaları ötekileştirilme deneyimlerini arttırmaktadır. Başka bir deyişle; göçmenlerin farklı kültürel, etnik ya da dini kimliklere ilişkin olarak ötekileştirilmeleri daha olasıdır. Bu önermenin sonucu olarak ötekileştirme, onunla mücadeleyi merkeze alan politikalar tarafından “aşılması olası” ve yapaylığı ima eden bir olgu olarak ele alınmaktadır. Bu çalışma; “öteki”nin varlığını kimliğin oluşumu açısından kaçınılmaz görerek ötekileştirmeyi “olumsuz bir doğal” yapan unsurun sosyal bilişsel bir süreç olan “stereotipleştirme” üzerinden okunması ve çözümün burada aranması gerektiği savını, Henri Tajfel ve John Turner’ın Sosyal (...) Kimlik Teorisini temel alarak günümüzde “öteki” sıfatının atfedildiği göçmenler bağlamında ele almaktadır. İnsanların tarih boyunca doğal, sosyal, politik ve ekonomik sebeplerle başvurduğu göç eyleminin günümüzde yoğun kitlesel hareketliliğe dönüşmesi göçmen kimliğinin görünürlüğünü arttırmış ve bu kimliği küresel ölçekte ötekileştirmenin nesnesi tayin etmiştir. Ötekileştirmenin psikolojik ve politik bileşenlerinin etraflıca tetkiki, söz konusu fenomenin toplumsal çıktılarının ayrıştırıcı etkisini bertaraf edebilmek için bir başlangıç noktasıdır. Bu gaye ile çalışmada ötekileştirme pratiğine farklı bir zaviyeden yaklaşılmış, ötekileştirmeyi toplumsal yaşam açısından olumsuz sonuçlara eviren bilişsel sürecin tespitleri göçmenler üzerinden değerlendirilmiştir. İlgili alanlarda teorik ve ampirik kaynakların taranması neticesinde edinilen bulgularla çalışma, sosyal psikolojik unsurların politik uygulamalara dâhil edilmesine dair yöntemlere ulaşma çabası ve toplumsal bütünlüğün tesis/muhafaza edilmesi için sunduğu politik psikolojik çözümler ile literatüre eklenmeyi hedeflemektedir.

Quine’s “Epistemology Naturalized” is the locus classicus of naturalism in epistemology. Many traditional epistemologists criticized the naturalization of epistemology specifically targeting this article. The critics argue that Quine abolishes the normativity of epistemology. For he proposes epistemology as a chapter of psychology. Laudan, like Quine, believes that epistemology should be naturalized. However, he criticizes Quine’s project of naturalization for similar reasons as Quine’s critics. Instead, he proposes a new project that he calls “normative naturalism”. In this work, I will first (...) argue against the critics of Quine and then argue that both Quine’s and Laudan’s naturalized epistemologies are hypothetically normative. -/- Quine’ın “Epistemology Naturalized” başlıklı makalesi epistemolojide doğallaştırma düşüncesinin klasik yapıtıdır. Pek çok geleneksel bilgi kuramcısı özellikle bu makaleyi hedef alarak epistemolojinin doğallaştırılmasını eleştirmiştir. Eleştirilerin odağında Quine’ın, psikolojinin bir alt bölümü haline getirerek, epistemolojinin normatifliğini ortadan kaldırdığı savı yer almaktadır. Laudan epistemolojide doğallaştırmanın gerekli olduğunu savunmasına karşın Quine’a yöneltilen bu eleştiriye katılmakta ve “normatif doğalcılık” adını verdiği yeni bir epistemolojik yaklaşım önermektedir. Bu çalışmada Quine’a yöneltilen eleştirinin yersiz ve Quine’ın doğallaştırılmış epistemolojisinin Laudan’ın normatif doğalcılığı gibi hipotetik normatif olduğunu tartışacağım. (shrink)

I show how classical and quantum physics approach the problem of randomness and probability. Contrary to popular opinions, neither we can prove that classical mechanics is a deterministic theory, nor that quantum mechanics is a nondeterministic one. In other words it is not possible to show that randomness in classical mechanics has a purely epistemic character and that of quantum mechanics an ontic one. Nevertheless, recent developments of quantum theory and increasing experimental possibilities to check its predictions call for returning (...) to the problem of comparing possibilities given by classical and quantum physics to accommodate and prove the existence of a `genuine randomness'. Recent results concerning `amplification of randomness' show that, in certain sense, quantum physics is in fact ‘more random’ that classical and outperforms it in producing a `truly random process'.

Âlemin zaman içinde vücûda gelip gelmediğine dair tartışma düşünce tarihinde kadim bir geçmişe sahiptir. Platon öncesi döneme kadar izleri sürülen söz konusu tartışma İslâm düşünce tarihinde de önemli bir yer işgal eder. Kelam ile felsefe ekolleri arasında cereyan eden münazaralarda kelamcılar, âlemin yokluğu üzerinde bir zaman geçtikten sonra yaratıldığını ileri sürerken filozoflar ise Allah’ın âlemden zamansal olarak değil zatî bir öncelikle mukaddem olduğunu savunurlar. Klasik dönem sonrası devam eden tartışmalarda probleme dair yeni çözümler ortaya konulmuştur. Bu makale klasik dönem sonrası (...) İslam felsefesinin önemli simalarından biri olan Molla Sadrâ’nın hudûs anlayışını konu almaktadır. Kendinden önceki hudûs yaklaşımlarını değerlendiren Molla Sadrâ, hareket-i cevherî teorisi bağlamında probleme yeni bir yorum getirir. Hareket ve zamanı, seyyal varlığın birer boyutu olarak gören Sadrâ’ya göre hareketin bizzat kendisi anlamına gelen yaratmanın olmadığı mevhum bir zamanın varlığı söz konusu olamaz. Bu anlamda âlem, öncesinde yokluk olan muayyen bir zaman diliminde yaratıldığı anlamda hâdis değil, yaratmanın zaman mecrasında gerçekleştiği anlamda hâdistir. Metafiziğin en girift meselelerinden biri olan bu problem hakkında Molla Sadrâ’nın yorumu kelamcılar ile filozoflar arasında kısırdöngüye dönüşen tartışmalarda bir uzlaştırma ve inkişaf sadedinde görülebilir.

The contributions gathered here demonstrate how categorical ontology can provide a basis for linking three important basic sciences: mathematics, physics, and philosophy. Category theory is a new formal ontology that shifts the main focus from objects to processes. The book approaches formal ontology in the original sense put forward by the philosopher Edmund Husserl, namely as a science that deals with entities that can be exemplified in all spheres and domains of reality. It is a dynamic, processual, and non-substantial ontology (...) in which all entities can be treated as transformations, and in which objects are merely the sources and aims of these transformations. Thus, in a rather surprising way, when employed as a formal ontology, category theory can unite seemingly disparate disciplines in contemporary science and the humanities, such as physics, mathematics and philosophy, but also computer and complex systems science.

Leibniz’s _principium identitatis indiscernibilium _excludes the existence of two different objects possessing all properties identical. Although perfectly acceptable for macroscopic systems, it becomes questionable in quantum mechanics, where the concept of identical particles is quite natural and has measurable consequences. On the other hand, Leibniz’s principle seems to be indispensable when we want to individuate an item and ascribe to it particular property (e.g. value of the projection of spin on a chosen axis). We may thus abandon the principle on (...) the quantum level, claiming it falsity here, or (better) try to find other ways of individuation of objects, possibly by adopting appropriately the very concept of it. All these problems, and many other connected with identity and indiscernibility of quantum objects, are thoroughly discussed in the book of Tomasz Bigaj, unique in the world literature due to its comprehensiveness.

Ikhwan-i Safa is known as a group of thinkers who wrote treatises in the style of the first scientific encyclopedia in the history of Islamic thought. Ikhwan-i Safa, which emerged in the vicinity of Basra at a time when religious and political conflicts were intense, aims to clean the religion, which they believe has moved away from its essence with false information and false thoughts, with philosophy. For this purpose, the Ikhwan's views on science and wisdom, who use all kinds (...) of religious, philosophical and scientific knowledge with an eclectic approach, are important in understanding the scientific understanding of the classical age of Islamic thought. Ikhwan-i Safa, who states that they are the heirs of every thought they find true, regardless of its source, advises its members not to be hostile to any of the sciences, not to turn their backs on any of the books, and not to be attached to any of the sects with bigotry. In this study, the approaches of İhvân-ı Safâ to the science of logic will be discussed within their understanding of science based on this broad acquis. According to Ikhwan-i Safa, who defines logic as the measure of philosophy and the instrument of the philosopher, since philosophy is the highest of human endeavours after Prophethood, logic, which is the measure of philosophy, must also be the highest of measures and instruments. In the study, it will be emphasized how the Ikhwan approached the science of logic in his treatises in the context of concept, proposition and syllogism, which are the main subjects of classical logic, and whether they made a unique contribution to this science.

Author's ideas on the end of the world and afterlife.

Miracles are extraordinary events that occur in the hands of those who claim to be prophets and which cannot be repeated by others. By these miracles, the prophets prove to society that the truths they convey are of divine origin. The miracles bestowed upon prophets vary according to the scope of the message they deliver and the interests and relevance of the societies with which they deal. Accordingly, Islamic scholars have classified miracles into three groups. The miraculous events that appeal (...) to people’s senses and lead them to the truths they convey by captivating their astonishment are called emotional miracles. Such miracles are events that occur without cause by overcoming the laws of nature, which are in the realm of causes, through the direct intervention of Allāh. On the other hand, spiritual miracles are truths that arouse the interlocutor’s interest in moral conduct and rational conclusions rather than in his sensory perceptions. Since these truths are attained through contemplation, they are not confined to a particular time and place, as in the case of emotional miracles. Some Kalām scholars have also considered the Prophets’ revelational knowledge about events that have occurred in the past or will occur in the future as miracles. They have studied these events that a person could not bear in the past or could not predict for the future under the title of "The news miracle" Among these three types of miracles, scholars have considered spiritual miracles superior to the others both in terms of the breadth of their influence and their continuity. That Prophet Muhammad (PBUH) is the last of the prophets, and that the teachings he received through revelation remain valid until the Day of Judgment necessitates that some of the miracles bestowed upon him must be of a quality that attracts the attention of all people. For this reason, Islamic scholars have placed the permanent miracle of Prophet Muhammad in the category of spiritual miracles. Scholars agree that his greatest miracle that has astonished all humankind is the Qurʾān. The clearest proof of this are the verses in the Qurʾān that challenge the opponents to bring a similar one. Allāh commands the disbelievers first to bring a similitude of the Qurʾān (al-Isrāʾ 17:88), then the equivalent of ten surahs (Hūd 11:13), and finally any surah of the Qurʾān (al-Baqara 2:23). Thus, the deniers are made aware of their inability to meet this challenge under gradually mitigating circumstances. Although scholars agree on the Qurʾānic miracle’s reality, they have expressed different views on its nature and essence. Thus, some scholars have argued that the miracle of the Qurʾān does not arise from some properties special to it but from the direct intervention of Allāh in human who have the ability to bring something like it. Most Islamic scholars, on the other hand, pointed out that the Qurʾān has aspects that exceed human powers in various fields, and they explained the inability to reply in the same vein to the Qurʾān due to its uniquenesses. Accordingly, some scholars have argued that miracles are perceptible, but it is never possible to define them. Other scholars, however, viewed miracles as an identifiable phenomenon and stated that the Qurʾān is an unusual and unique book in terms of verses. In this article, the questions Why was the Quran sent down as a miraculous Kalam with an attribute not found in other divine books and in what way did the Qurʾān make people weak to have a similar of it? were scrutinized, thus, some fundamental questions regarding the nature and character of iʿdjāz al-Qurʾān are elucidated. Since the topic deals with history and literature, scanning sources and data analysis were mainly used as methods in the research. The results can be summerized as follows: Although the Prophet was supported by both emotional and mental miracles in proving the Prophetic case, his greatest miracle is the Quran. The miracle of the Qurʾān is different from the other miracles, based on both the challenging verses and the Prophet's explanations of the miracles. The reason for this difference lies in the fact that the miracle of the Qurʾān is based on reason, unlike the other miracles which are emotional. Most Islamic scholars who deal with the miracle of the Qurʾān emphasize the issues of rhetoric, verse, style, and content. At this point, they emphasized that the Qurʾān has a unique expression and content that cannot be surpassed. (shrink)

This paper compares attitudes towards achievement and power orientation as between Turkish, British and Irish managers and discusses the issue from a business ethics point of view. The concept of achievement and power orientation and its impacts on business ethics is discussed. This research is part of a larger cross‐cultural study that examines leadership styles and managerial attitudes in Britain, Turkey and Ireland. Intensive structured interviews were conducted for data gathering process. Results revealed that Irish and Turkish managers show a (...) higher achievement orientation level than their British counterparts. On one hand this situation may give some advantages to Turkish and Irish managers in developing leadership qualities, on the other hand, it can also lead to some difficulties in ethical business practices. Therefore, corporate social responsibility becomes a more important issue to be pursued in Turkey and Ireland. British and Irish managers, however, showed a higher power orientation level than Turkish managers. The low level of power orientation of Turkish managers can be explained by cultural and historical conditions that still affect modern Turkish society. Previous cross‐cultural studies support the results of this paper. (shrink)

Diffusion of responsibility is a well-known effect widely studied in a real-life setting. It can occur in a situation in which the more people observe a crisis event, the less likely it is that someone will react and provide real assistance. These days of a galloping digital revolution a question is to be raised as to whether the same effect can be observed in the online space of communication. In order to investigate this phenomenon we designed a study aimed at (...) testing whether people exposed to a situation of cyberbullying will decide to take action against it depending on how many other Internet users are also aware of that crisis. Results obtained by us confirmed the existence of the diffusion of responsibility in the Internet similar to that observed in our daily lives. We also confirmed that a well-known influence technique “Even a penny will help” (in our study “every reaction will help”) can be effectively used to model behaviour online. In our times of digital revolution, those outcomes can be a step both toward understanding human behaviour in the online setting, showing us that it is not that different from the one presented in real live face-to-face communication and toward helping deal with antisocial behaviour people face online on a daily basis.

This article explores micro- and macro-level variables that influence the incidence of bribery payouts by firms. A rich data set with information from 55 countries was utilized to achieve this objective. Results of logit regression models indicate that there are a number of micro- and macro-level factors that significantly affect the incidence of bribery payouts. This suggests that it is not only the characteristics of a firm but also the environment of doing business that affect the firm's bribery decision. The (...) results of this study provides information that may help firms develop strategies to reduce corruption in their respective industries and thereby improve their image of corporate social responsibility. The analysis also points to possible policy directions that governments could undertake in order to reduce the incidence of bribery in their country. (shrink)

This paper identifies that Information and Communication Technology (ICT) has a negative effect on software piracy rates in addition to consolidating prior research that economic development and the cultural dimension of individualism also negatively affect piracy rates. Using data for 59 countries from 2000 to 2005, the findings show that economic well-being, individualism and technology development as measured by ICT expenditures explain between 70% and 82% of the variation in software piracy rates during this period. The research results provide important (...) implications for policy makers and business practitioners to help reduce software piracy. (shrink)

It is widely believed that mathematics carries a substantial part of the explanatory burden in science. However, mathematics can also play important heuristic roles of a different kind, being a source of new ideas and approaches, allowing us to build toy models, enhancing expressive power and providing fruitful conceptualizations. In this paper, we focus on the application of dynamical systems theory (DST) within the extended cognition (EC) field of cognitive science, considering this case study to be a good illustration of (...) a general phenomenon. In the paper, we justify both a negative and a positive claim. The negative claim is that dynamical systems theory hardly plays any explanatory role in EC research. We justify our claim by analyzing several accounts of the explanatory role of mathematics and stressing the way mathematical arguments are used in explanations. Our positive claim is that even though, for now, DST has no explanatory power in many of the EC approaches, it still plays an important heuristic role there. In particular, using mathematical notions improves the expressive power of the language and gives a sense of understanding of the phenomena under investigation. The case study of EC allows us to identify and analyze this important role of mathematics, which seems to be neglected in contemporary discussions. (shrink)
