A critical edition of "Tahdhīb Al-Akhlāq", a treatise ascribed to the Jacobite theologian, logician, and translator in Abbasid period, Yahya ibn Adi.

Abū al-Ḥusayn Aḥmad b. Yaḥyā Ibn al-Rāwandī(815–860 or 910), perhaps one of the most controversial figures in early Islamic history, is frequently called the “arch-heretic” (zindīq or mulḥid) of Islam. He was born in Khurasan around 815 CE. but flourished among intellectuals in ninth century in Baghdad. Around the year 854, he left Baghdad to escape political persecution and died either in 860 or in 910, according to some sources. The details of his early life are unknown, and documentation of (...) Ibn al-Rāwandī began to surface once he became an intellectual enemy of his fellow Muʿtazilites, the rationalist thinkers of Islamic thought at the time. Information on Ibn al-Rāwandī is gathered mostly from the writings of his opponents. From these sources, we learn that both Muslims and non-Muslims (especially Jews) wrote polemics against Ibn al-Rāwandī in which they acknowledged the serious threat his work posed not only to Islam, but also to Judaism and all Abrahamic religions.

Service workers are more prone to experience customer mistreatment because of their frequent interactions with them. Hence, it compels them to the level where their performance is compromised. Employees who face customer mistreatment feel ill-treated and develop the desire for revenge. Based on the social exchange and displaced revenge perspective, this study examined the relationship between customer mistreatment and coworker undermining, and individual-level resource-based moderator service rule commitment for this relationship. An analysis of time-lagged, dyadic data from the Chinese service (...) industry confirmed that customer mistreatment significantly predicted coworker undermining. In addition, in support of the resource perspective, employees’ SRC effectively restricts an effect of customer mistreatment on coworker undermining. Finally, this study contributes to the customer mistreatment and coworker undermining literature by highlighting their relationship. This study also shows the importance of SRC in restraining the adverse effects of customer mistreatment. (shrink)

The book under study is "Kitāb al-Uṣūl" and its commentary "Sharḥ al-Uṣūl" written by Ibn Ḥallād al-Basrī, one of Abū Ḥāshim al-Jubbāʾī's leading students. This work is the result of the Mu'tazilite Manuscripts Project conducted by Sabine Schmidtke and D. E. Sklare, and has been published in an edited edition by Camilla Adang, Wilferd Madelung, and Sabine Schmidtke. The study, entitled "-A Critical Edition of the Ziyādāt Sharḥ al-uṣūl by the Zaydī Imām al-Nāṭiq bi-l-ḥaqq Abū Ṭālib Yaḥyā b. al-Ḥusayn b. (...) Hārūn al-Buṭḥānī " begins with quotations from Ibn Ḥallād's Kitāb al-uṣūl or its incomplete commentary, Sharḥ al-uṣūl. This is followed by various quotations written in addition to Ibn Ḥallād's incomplete commentary, which are mostly from Kādī ʿAbd al-Jabbār's Sharḥ. Then the commentary of the Zaydī Imam Nāṭīq-Bilḥāq is added, and finally, the text is completed by the commentary of his student and annotator, Abū al-Ḳāsīm Aḥmad b. Mahdī al-Ḥasan. Although the text does not directly define the usūl al-hamsa, the reader can recognize this progression. Beginning with tawhid, the text moves on to justice, followed by va'd-va'id, and finally concludes with topics such as predestination, sustenance, accident, and fate. (shrink)

_This mirror for princes sheds light on the relationship between spiritual and political authority in early modern Egypt_ This guide to political behavior and expediency offers advice to Sufi shaykhs, or spiritual guides, on how to interact and negotiate with powerful secular officials, judges, and treasurers, or emirs. Translated into English for the first time, it is a unique account of the relationship between spiritual and political authority in late medieval / early modern Islamic society.

This piece offers an edition, translation, and analysis of a newly discovered text by Yaḥyā Ibn ʿAdī, a leading Aristotelian of the Baghdad school in the tenth century. It briefly discusses what Aristotle meant, at the end of the Physics, by saying that the Prime Mover is “in” the outermost heaven. Ibn ʿAdī argues, in part through an exhaustive discussion of the senses of the word “in,” that God is in the sphere only in the sense that an object of (...) intellection is in an intellect. This solution is discussed against the background of ancient commentaries on the same passage. (shrink)

This article offers an analysis, translation, and edition of a brief, recently uncovered Arabic text by the tenth-century CE Christian Aristotelian thinker Yaḥyā ibn ʿAdī. Ibn ʿAdī here takes issue with an argument for the existence of God, widely used in kalām. According to this argument, bodies cannot exist without being either in motion or at rest; motion and rest must begin; therefore all bodies and hence the universe as a whole must have begun. Ibn ʿAdī diagnoses various flaws in (...) this reasoning, including a supposed part–whole fallacy. The analysis of the text shows how it fits into Ibn ʿAdī’s intellectual profile and the project of the Baghdad Aristotelian school. (shrink)

The interaction between Zaydism and Muʿtazilism, which is claimed to date back to the formation periods, took place when Zaydī scholars studied Muʿtazilite thought in Baghdad intensively and directly from the Mu'tazilite theologian Abū ʿAbd Allāh al-Baṣrī as part of the curriculum, and especially the Basra school of Muʿtazila was influential in the theological thoughts of the Zaydis of Tabaristan/Hazar. In this process, Zaydī scholars such as al-Muʾayyad bi-llāh Aḥmad b. al-Ḥusayn al-Hārūnī and al-Nāṭiq bi-l-Ḥaqq Abū Ṭālib Yaḥyā b. al-Ḥusayn (...) took lessons from the Mu'tazilite theologian Abū ʿAbd Allāh al-Baṣrī in Baghdad. In the same period among the Zaydī scholars who studied theology from Abū ʿAbd Allāh al-Baṣrī and deliberated with him was Imam al-Mahdī li-Dīn Allāh Abū ʿAbd Allāh b. al-Dāʿī, who has been one of the important figures Zaydī-Muʿtazilī interaction can be pursued. Ibn al-Dāʾī, who has detailed information both his political life and scholarly activities in classical sources, wrote many works in the fields of theology and fiqh, but most of his studies have not survived to the presdent day or have been lost, except for the treatise al-Dāʿī, Ḥaqāʾiq al-Aʿrâḍ, which was identified and confirmed as belonging to Ibn al-Dāʾī, with the discovery of a collection of Zaydī-Muʿtazilite studies. In his only extant work, Ḥaqāʾiq al-Aʿrâḍ, Ibn al-Dāʾī classified the accidents on the basis of different criteria and dealt with their realities and states in accordance with the division and evaluation of accidents in later Muʿtazilite sources. This study is one of the rare studies known to have been written on the subject, which contains very detailed division of accident. The publication of this work is important both for the elucidation of the Zaydiyya-Muʿtazilite interaction in the relevant period and for a better understanding of the early theology's understanding of existence. This article will present an analysis of Ibn al-Dāʾī's treatise Ḥaqāʾiq al-Aʿrâḍ and its critical edition using three different manuscript copies. The publication of this study on accidents, one of the most fundamental topics of kalām, will contribute to the understanding of the holistic theological systems of Zaydiyya-Muʿtazila. With the publication of this work, it will be revealed that the interaction between Zaydiyya and Mu'tazila in the 4th/10th century on the subject of accidents was quite intense. (shrink)

L'A. confronta due commenti su quello che nel mondo arabo viene considerato il primo libro della Metaphysica di Aristotele: alpha Elatton. Dopo averne delineato i contenuti e la penetrazione nel mondo arabo grazie alle traduzioni di Ustat e Ishaq ibn Hunayn, l'A. esamina due importanti commenti a quest'opera: Yahyá Ibn 'Adi, un commentatore cristiano della scuola di Baghdad e Averroè . I due autori leggono il testo in modo molto diverso: questo suggerisce una grande differenza tra Averroè e la (...) scuola di Baghdad, sebbene il filosofo andaluso abbia ammirato e seguito il lavoro di al-Farabi. In particolare è naturale il rifiuto da parte di Averroè di introdurre un'inchiesta puramente teologica nella trattazione, punto accettato invece da Ibn 'Adi, secondo il proposito di Averroè di rimarcare il fondamento fisico della metafisica, come è possibile comprendere soprattutto grazie alla lettura del Trattato.

The “lost” Yaḥyā ibn ʿAdī treatises recently discovered in the Tehran codex Marwī 19 include a record of a philosophical debate instigated by the Ḥamdānid prince Sayf-al-Dawla. More precisely, Marwī 19 contains Yaḥyā’s adjudication of a dispute between an unnamed Opponent and Yaḥyā’s younger relative Ibrāhīm ibn ʿAdī (who also served as al-Fārābī’s assistant), along with Ibrāhīm's response to Yaḥyā’s adjudication, and Yaḥyā’s final word. At issue was a problem of Aristotelian exegesis: should “body” be understood as falling under the (...) category of substance or under the category of quantity? The unnamed Opponent argues that body is a species of substance; Ibrāhīm argues that technically speaking, body is a species of quantity, and hence an accident; and Yaḥyā judges that body is a species of substance, though for very different reasons than the Opponent gives. For the first time, the Arabic text of this exchange is edited and translated into English. Also provided is an Introduction that sets the debate in historical context, and discusses in particular the possible influence of John Philoponus. The debate is interesting and important not only because of the philosophical ramifications of the issues under discussion, but because it constitutes evidence of dialectical practice among Arabic-speaking philosophers from the middle of the 10th century.

This article studies Ibn al-Haytham’s treatment of the common notions from Euclid’s Elements (usually referred to today as the axioms). We argue that Ibn al-Haytham initiated a new approach with regard to these foundational statements, rejecting their qualification as innate, self-evident, or primary. We suggest that Ibn al-Haytham’s engagement with experimental science, especially optics, led him to revise the framing of Euclidean common notions in a way that would fit his experimental approach.

Rationalities is being have sufficient as the new god of modern humans. Being the fuel of spirit, they try to negate “Being” or metaphysical. The impact of it they alienate the social crisis and spiritual crisis. The extremely spiritual crisis generates atheism or at least agnostic. They leaned on the knowledges and technologist which have suspected them as the driving force of modernization process have resulted the higher degree of modern humans’ rationality. Instead of losing the beliefs is precisely created (...) the public sphere. The humans modern try to find the spiritual leaned by the Sufism way. One of the interesting Sufism figures to be studied is Ibn Atha`illah. This paper studies about the Ibn Atha`illah’s view in the modern of philosophical Sufism. Practically he was more emphasize the Sufism’s value in ma’rifat view. He is also the main figure of Sufism but his activities or influences was only in it. Ibn Atha`illah was known as the master of Islamic laws in mazhab Maliki and akidah, the competence which as a rule of religious exoteric. (shrink)

The fame of the Jacobite Christian Abu Zakariyya Yahya ibn ''Adi (893 bis 974) as in influential philosopher and as en eminent apologist of the Christian faith has been founded on reputation rather than on the study of his work. When Augustin Perier compiled the first list of his writings in 1920, most of his philosophical works were believed to be lost. Most recent publications have enabled us to appraise his merits as a translator an commentator of Aristotle. But only (...) a few of his philosophical monographs were available until an important collection of his treatises was discovered inthe libraries of Tehran. This. at last, has enabled us to study in detail his contribution to logic, his treatment of physical and metaphysical problems, and his position on questions of Muslim "kalam". The Monophysite theology of Yahya ibn ''Adi, on the other hand, though better known through the studies of G Graf and A. Perier, still awaits renewed examination. The most important works in this field have not even been published. So the new inventory of his writings is intended to provide the basis for a reassessment of his merits as an Aristotelean as well as a Christian thinker.The study contains a survey of biographical data, detailed bibliographical information on manuscripts and printed works and summaries of most the unpublished texts.

This research aims to describe and analyze Ibn Taymiyyah’s philosophical-constructive critique of Ibn ‘Arabī’s waḥdat al-wujūd thought. The method used in this research is descriptive-analytical. The primary data used in this research are the works of Ibn Taymiyyah and Ibn ‘Arabī. Meanwhile, secondary data in this research are books, journal articles, and other websites that discuss the thoughts of Ibn Taymiyyah and Ibn ‘Arabī. The research results show that Ibn Taymiyyah rejected thinking of waḥdat al-wujūd, because of his understanding of (...) the doctrine of waḥdat al-wujūd This is different from the understanding of Ibn ‘Arabī and his followers. According to Ibn Taymiyyah, waḥdat al-wujūd is the equating of God with nature. In modern terms synonymous with pantheism. Ibn Taymiyyah said those who adhere to waḥdat al-wujūd say that existence is one, and wajib al-wujūd what God has is the same as possible waḥdat al-wujūd that a creature has. Ibn Taymiyyah’s criticism emerged because he only saw aspects of tashabbuh (equation of God with his creatures) from understanding waḥdat al-wujūd, and did not see aspects of tanzīh (purification of God from the likeness of his creatures) from the same understanding. These two aspects are combined into one in the teachings of Ibn ‘Arabī. Even according to Ibn Taymiyyah, the understanding that considers God’s existence to be united with the existence of His creatures is a form of disbelief for God, a form of disbelief and shirk in Him.

The aim of this paper is to prove how what is apparently a mistake made by Plutarch, wheter deliberate or not, in his reference to the arson attack of Caesar´s soldiers in Alexandria as the end of the famous Library, show us the common sense of the term “bibliotheke” from that time up to now. Coming to this conclusion has required a detailed analysis of the Library of Alexandria since its birth applying Aristotelian doctrine to its configuration not only as (...) an organized space for books but also as an imaginary reading room from which the helenistic world of relations is established. In a second approach, we focus the attention on the change occurred in this collection with the introduction of alphabetical order and, then, with the philological activity of Callimachus. As a result of his Pinakes, the platonic concept of daimon, “guide”, became the first characteristic o a philologist or librarian. Using the information ordered in the Pinakes anybody could be a librarian and find a library anywhere. The old megále bibliotheke of Alexandría remains only with the idea of the conservation of original papyrus. This is de reason of the enigmatic sentence of Plutarch announcing the end of this situation caused by the action of the fire. (shrink)

This is an analytical examination of Ibn Khaldun's epistemology, centred on Chapter Six of the Muqaddima. In this chapter, entitled The Book of Knowledge (Kitab al'Ilm), Ibn Khaldun sketched his general ideas about knowledge and science and its relationship with human social organisation and the establishment of a civilisation.

After the problems of epistemology, the most fundamental problem of Islamic philosophy is that of causality. Causality has been studied from various perspectives. This paper endeavors first to analyze the issues of causality in Islamic philosophy and then to critique them. A sketch is provided of the history of the development of theories of causality in Islamic philosophy, with particular attention to how religious considerations came to determine the shape of the philosophical theories that were accepted. It is suggested that (...) outstanding philosophical and theological problems that have plagued the tradition of Islamic philosophy require a new approach to the issue of causality. (shrink)

One of the fundamental problems of Theoretical Mysticism is the explanation of the world as being something other than God after having accepted the Unity of Existence. This paper seeks to present, after having explained certain necessary premises, the theory of manifestation as one that can explain and analyze multiplicity. In this article we especially seek to solidify the relation of such claims to mystics in general and to the adherents of the Ibn ‘Arabian school of thought in particular. This (...) is especially important because in some of the works of many specialists in this field we find that some unrealistic claims have been definitively attributed in to the Great Sheikh. The only way to counteract such false claims, in any field, including Theoretical Mysticism, is to make it binding upon ourselves to delve into the views of others in a cautious way. We must take the apparent meanings of the sayings of the mystics as a proof in this matter. Therefore the method of research of the writer of this article is to relate the sayings of the Great Sheikh and his commentators while commentating upon and analyzing them as well. (shrink)

Bu araştırma hicri birinci asrın ilk yarısında varlık gösteren Basra’nın, fıkhıyla meşhur bazı sahâbîlere ev sahipliği yapmasına rağmen hadis ve fıkıh ilimlerinde, aynı dönemde öne çıkan Kûfe’den geri kalmasının muhtemel sebeplerine odaklanmaktadır. Söz konusu sahâbe arasında öne çıkanlar, Basra’da on iki sene ikamet etmiş olan Ebû Musa el-Eş’arî ve dört sene bulunan İbn Abbas’tır. Mezkûr iki sahâbenin fıkhî müktesabatlarının yanında çok sayıda hadis rivayetine sahip olduğu da bilinmektedir. Ancak buna rağmen her ikisinin de İbn Mes‘ûd’un, Kûfe’de yaptığı etkiyi gösterdikleri söylenemez. (...) Araştırmada, Basra’da meskûn bulunan sahâbeyle ilgili rivayetlerin tahlil ve değerlendirmesine dayalı bir yöntem takip edilmiş olup, özellikle sahâbe ile tâbiînin ilmî ilişkilerine yoğunlaşılmıştır. Bununla beraber coğrafya ve kuruluş bakımından benzerlik gösteren Kûfe şehrindeki sahâbenin ilmî etkisi ve tâbiîn neslinin faaliyetleri bakımından bir takım karşılaştırmalarda bulunulmaktadır. Makalenin, konu hakkında öngördüğü birinci ihtimal, söz konusu sahâbîlerin ordugâh şehrinde yaşamanın gereği olarak fetihlerle meşgul olmalarıdır. Bu sonuç ilk olarak Ebû Musa el-Eş’arî’nin sireti üzerine yapılan incelemelerde ortaya çıkmıştır. Söz konusu ilmî gecikmeye sebep olan ikinci ihtimalin ise bahsi geçen sahâbenin ilimlerini yaymak adına aktif davranmamaları olduğu söylenebilir. Bu durumda sahâbenin ilmî kişiliklerinin önemli bir rol oynadığı düşünülmektedir. Diğer bir ihtimal, Basra’daki tâbiîn neslinin, sahâbeden ilim alma hususunda sarfettikleri çabanın, Kûfelilere kıyasla daha az olmasıdır. Bahsi geçen durumda Basra’nın bedevî kabile yapısının önemli bir etkili olduğu düşünülmektedir. Konuyla ilgili zikredilebilecek son ihtimal ise ilmî yapının teşekkül etmeye başladığı süreçte vuku bulan fitne ve karışıklıklardır. Nitekim bir müddet valilik görevini yürüten İbn Abbas’ın, bu süre zarfında ilim ve eğitim faaliyetleriyle ilgilenemediği görülür. Özetle araştırmanın ulaştığı en önemli sonuç; Basra’nın hicri birinci asrın ilk yarısında, İbn Mes’ûd tarafından kurulan Kûfe’ye kıyasla hadis ve fıkıh ilimlerinde gelişmiş bir şehir olmadığıdır.
