Spontaneous mirror self-recognition is achieved by only a limited number of species, suggesting a sharp “cognitive Rubicon” that only few can pass. But is the demarcation line that sharp? In studies on monkeys, who do not recognize themselves in a mirror, animals can make a difference between their mirror image and an unknown conspecific. This evidence speaks for a gradualist view of mirror self-recognition. We hypothesize that such a gradual process possibly consists of at least two independent aptitudes, the ability (...) to detect synchronicity between self- and foreign movement and the cognitive understanding that the mirror reflection is oneself. Pigeons are known to achieve the first but fail at the second aptitude. We therefore expected them to treat their mirror image differently from an unknown pigeon, without being able to understand that the mirror reflects their own image. We tested pigeons in a task where they either approached a mirror or a Plexiglas barrier to feed. Behind the Plexiglas an unknown pigeon walked at the same time toward the food bowl. Thus, we pitched a condition with a mirror-self and a foreign bird against each other, with both of them walking close toward the food bowl. By a detailed analysis of a whole suit of behavioral details, our results make it likely that the foreign pigeon was treated as a competitor while the mirror image caused hesitation as if being an uncanny conspecific. Our results are akin to those with monkeys and show that pigeons do not equal their mirror reflection with a conspecific, although being unable to recognize themselves in the mirror. (shrink)

It is rather difficult to detail the history of Abyssinian Judaism. Although there is no clear information on the subject, the existence of a Jewish ethnic group in Abyssinia is generally explained as the result of contact with members of the ancient Jewish community. Recent research point out a much more different and complex picture of Judaism in Abyssinia. First of all, it is important to know that in the early stages of Abyssinia, an ethnically and religiously differentiated (distinguishable) Jewish (...) community has yet been encountered. What should be questioned in the study of Abyssinian Judaism is the Ethiopian Orthodox Tawhid Church (Abyssinian Orthodox Church) itself, which for many years served as a vehicle for transmitting Hebrew elements. In that sense Abyssinian Orthodox Christianity offers one of the most unique expressions of world Christianity; is still observing the Sabbath and still continuing to circumcise boys. Moreover, it maintains the belief that the Ark of the Covenant was brought to Ethiopia before the destruction of the Solomon’s Temple. If Abyssinian Christianity which has a Judeo-Christian tradition is to be igno-red and a separate history of Abyssinian Judaism (as a community) is to be established with evidence, it is understood that the starting point could be after the 14th century. The claim of the study is that the formation process of Abyssinian Juda-ism may have been a development formed by Abyssinia's own choice with the acceptance of Christianity rather than a direct continuation of a Jewish group. The weight of Jewish influence in the Falasha community, which is claimed to be the present representative of Abyssinian Judaism, is related to the orientation of the local monks after the 15th century and the result of the texts they convey (transfer). When the ethnic and religious positions of the Falashas are evaluated objectively, the Falashas are directly embedded in the Judeo-Christian tradition of Abyssinia. Therefore, it is understood that Falashas cannot be held responsible for Jewish influence in the face of Abyssinian Christianity which has followed a Judeo-Christian tradition for many years.

Osmanlı sanatçıları tarafından, zamanla bozulan nüshalardan çıkarmak suretiyle ya da müzayedelerde satışa sunulan hat ve minyatürleri bir şekilde temin edip, daha fazla yok olmalarının önüne geçmek amacıyla uygulanan onarım işlemine vassale tekniği, bu tekniği uygulayan sanatçıya da vassal adı verilmiştir. XVII. yüzyılda Kalender Paşa tarafından hazırlanan I. Ahmed Albümü ile öne çıkan vassalecilik, XVIII. yüzyılda gelişerek devam etmiş, özellikle koleksiyoner Mehmed Emin Efendi ve adı bilinmeyen vassallar tarafından onarım tekniği olarak uygulanmıştır. Ancak onarım işlemi olarak başlayan bu teknik, Kalender Paşa (...) ile birlikte sanata dönüşmüş ve başta murakkalar olmak üzere çok sayıda resimli nüshalar hazırlanmıştır. Bu makalede, XVIII. yüzyılda Osmanlı kitap sanatlarında karşılaşılan farklı bir şekilde uygulanması nedeniyle, önemli bir yere sahip vassale tekniğinin incelenmesi amaçlanmaktadır. Bu kapsamda, söz konusu yüzyıllarda karşılaşılan ve kitapları onarmak amacıyla kullanılan vassale tekniğinin yüzyıllara bağlı olarak sanatçılar ve koleksiyonerler tarafından uygulanış biçimi, Osmanlı kitap sanatları içinde önemli bir yeri olan murakka ve resimli elyazmaları üzerinden seçilen örnekler ışığında incelenmiştir. Araştırma kapsamında ulaşılan örnekler arasından seçilen nüshalar; “Topkapı Sarayı Müzesi Kütüphanesi B.408 numaralı I. Ahmed Albümü, H.1115 numaralı Hamse-i Nizami, H.2155 numaralı Albüm, H.2135 numaralı Murakka ve İstanbul Üniversitesi Nadir Eserler Kütüphanesi Türkçe Yazmalar Koleksiyonu 06131, 06132, 06133 numaralı Şehnâme Tercümesi” adlı koleksiyonlarda yer almaktadır.

Aristotle, who has come to the forefront with the significant contributions to the development of logic throughout the history, has been the source of different perspectives for his subsequent studies with his philosophical system and logic. Many thinkers and logicians, including Russell, have come face to face with Aristotle and his ideas, regardless of whether they are positive or negative. The aim of this study is to explain the meaning of Aristotle's syllogism theory from Russell's point of view. In accordance (...) with this aim, firstly the effects of the theory of syllogism on the development of logic and then Aristotle's own explanations are given. The study continues by examining the formal and contextual details of syllogism inferences from Russell's consideration. In the conclusion part, it is stated how studies in logic, which grew in size with the important contributions of Aristotle, reached a different point with the tradition in which Russell was involved. In the light of all these explanations, it will be seen that Aristotle and Russell look for ways to think correctly and consistently in their work, and they want to express the validity of inferences according to formal patterns.

Dil, dünya ile düşünce ilişkisini dil aracılığıyla kurma ve dil bağlamında bilgiye açıklık kazandırma amacını güden mantıkçı pozitivizm, 20. yüzyılın önemli düşünsel eğilimlerinden biridir. Bu anlayışa göre başta felsefe olmak üzere disiplinlerdeki çeşitli konu ve problemler, yeni mantığın metotları eşliğinde geliştirilen dilsel çözümleme bağlamında tahlil edilmelidir. Bu çerçevede, bilgi değeri taşıyan anlamlı tümceler ile bilgi değeri taşımayan anlamsız tümceler arasına çizilebilecek sınırın işareti olan “anlam kriteri”, mantıkçı pozitivist düşünürlerin temel meselesi haline gelmiştir. Buna dayanarak bilgi değeri taşımamaları ve anlamsız olmaları (...) nedeniyle metafiziğin tümcelerini, felsefeden elimine etme girişimleri ortaya çıkmıştır. Çalışma içerisinde dikkate alınacak olan hususlar, bahsi geçen bu girişimin ilk oluşturucularından olan ve anlamı, yeni mantık çerçevesinde öncelikli bir şekilde inceleyen Frege, Russell ve Wittgenstein’ın yaklaşımlarını incelemektir. Öyle ki bu düşünürlerin izinden giden mantıkçı pozitivistler, anlam sorunu etrafında metafiziğin felsefeden elenmesi çabasını taşımış ve ilerletmişlerdir. Dolayısıyla “anlam”ın yeni mantığın metotları bağlamında nasıl temellendirildiği konusu, bu girişimin kökenlerinin açıklığa kavuşturulması noktasında oldukça mühim bir yere sahiptir. Çalışmanın sınırları içerisinde mantıkçı pozitivist düşünürlerden, dilin mantıksal sentaksına bağlı bir şekilde “doğrulama ile anlam” arasındaki ilişkiyi vurgulayan Carnap’ın ve “anlam kriteri ile doğrulama ilkesi” arasında kurulan bağ ile ön plana çıkan Ayer’in düşüncelerine değinilecektir.

Summary Today's “Topkapi” in Istanbul is generally accepted as the Gate of Saint Romanos. A newly noticed inscription on the lintel above the entrance of so called fourth minor gate clearly indicates that not Topkapi but this gate was originally the Gate of Saint Romanos.

Im Garten des Museums von Afyon, dem antiken Akronion, befinden sich zwei Teile eines monumentalen Kapitells. Seine beträchtlichen Maße und das Kaisermonogramm (s.u.) lassen in ihm den Rest eines Ehrenmonuments erkennen (Höhe ca. 1.00 m, obere Breite ca. 1.00 m). Nach Auskunft der Museumsleitung wurde es Mitte der 80er Jahre in Huhut (das antike Synada, 26 km südlich von Akronion/Afyon) bereits beschädigt entdeckt und war während des Transports ins Museum in zwei Teilen zerbrochen. Weitere Schäden enstanden an der Halspartie, an (...) zwei Schauseiten sowie an der oberen Platte. Auf der Oberseite befinden sich keinerlei Einlassungen für eine Statue oder einen Kämpfer. Das Kapitell wurde aus „synadischem Marmor” gefertigt, der tatsächlich in den Marmorbrüchen des phrygischen Dokimaion (heutige Isçehisar, 21 km nordöstlich von Afyon) gewonnen wird. Der weiße Marmor von Dokimaion wird im heutigen türkischen Sprachgebrauch als „Afyon-Kaymak/Afyon-Sahne”, „Afyon-Beyaz/Afyon-Weiss” oder „Afyon-Şeker/Afyon-Zucker” bzw. als „Afyon-Çizgisiz-Şeker/Afyon-Zucker ohne Linien” bezeichnet.

The so-called Artukid bowl is the only enameled object which includes both an Arabic and a Persian inscription. According to the Arabic inscription the Artukid ruler Rukn ed Devle Davud was the owner of this object. Although its provenance is still unclear, the technique and material show similarities to several Byzantine examples. For this reason the bowl has been interpreted as a royal gift from Constantinople to the Artukid ruler. It has also been attributed to Georgia or to Mesopotamia. The (...) Arabic inscription includes a long list of titles of Rukn ed Devle Davud, like "Katl al Kafara" or "Samsam al Milla" . I, however, cannot imagine that a Christian emperor would address an Islamic ruler with such terms. The sender of the bowl was most likely another Islamic monarch. In addition, the Persian inscription leads to suspect that the sender had a close relationship with the Persian language and culture. Most probably he was a member of the royal Seljuk family in Anatolia. What was the reason for sending such a gift to a minor local ruler ? The written sources inform us that the daughter of the Seljuk Sultan Kiliç Aslan I. , Sacide Hatun , was married with Rukn ed Devle Davud, owner of our bowl. Furthermore the sources tell us that bowls were sometimes a part of the dowries. All these factors lead me to suggest that the so-called Artukid bowl was produced as a wedding gift in a Greek atelier of Seljuk Anatolia. (shrink)

English Summary The main focus of this article is a church, the picture of which is shown on a gravure by Gugas İnciciyan and called Arslanhane (Menagerie)/Nakkaşhane (House of painters). The church has a central dome, an apsis and a semi dome at the west side and looks like a little model of the Hagia Sophia. It was erected above an other building with a central arch. This resembles descriptions of the Chalke gate and the Chalke church in several written (...) sources. Some chraracteristic marks of İnciciyan's church can also be discovered on some other drawings from various artists (Matrakçi Nasuh 1537; Melchior Lorichs, 1559; Cornelius Loos, 1710). A comparison with them helps us to localise it on the southern side of the former university building of Gaspare Fossati. Written sources inform us that the so called Arslanhane/Nakkaşhane of Inciciyan was not the only the building, which was converted to a menagerie. The church of Johannes in the Diippion and an other building, near the southwest corner of the Hagia Sophia were also used as menagerie during the Ottoman period. Especially the second one can be seen on various drawings. In our opinion Mango's identification of a church drawn by Willey Reveley (1786) with the Chalke, must be reviewed, since it was probably that of Theotokos Varaniotissa, which was renewed in the late Byzantine era.

Why have debates around the Muslim hijab become increasingly acrimonious? Islamophobia has led to the rise of far-right groups, with calls in Europe and the US for banning headscarves and minarets on mosques. In India, sectarian violence continues unabated since 1947, with hate speech becoming progressively overt. The first half of this paper examines why the Muslim hijab has become the lone metaphor for debates about identity formation, to the exclusion of veiling prevalent in other religious and cultural contexts. How (...) would Muslim migrant writers find these debates helpful for their situation in their countries, whether original or adoptive? How can marginalized writers resist discrimination and exclusion from mainstream life? The second half of this paper focuses on the belief in the transformative power of Sufism that the Turkish-German writer Zafer Şenocak shares with the mystics Yunus Emre and Jalaluddin Rumi, and the Bengali poet Rabindranath Tagore. For Şenocak, Sufism allows a religiosity that is not only compatible with, but also perceivable in sensuous experience. Sufism thus serves as a “third space,” a term defined by the renowned culture critic Homi Bhabha as an ambiguous, ineffable area that develops when two or more individuals/cultures interact.
