Khalīfa b. Khayyāt(d. 240/854-855) was an historian- muḥaddith in the ʿAbbāsid’s period. There are references in sources to his competence in history and lineage rather than Ḥadīth. Two works of him have survived. The first one is al-Ṭabaḳāt which is about study of men and the second one is al-Taʾrīkhwhich chronologically narratesthe events in the history of Islam until 232 AH. The latter is the most significant work to be applied for the historiography of ibnKhayyāt. In this article, Khalīfa b. (...) Khayyāt’s methodology in historiography is examined. In this study, the early period of Islamic histography is handled and the subject is discussed comparatively. The main characteristics of his historiography are his adoption of a chronological style that facilitates the follow-up of the book, his knowledge for the lineage of those who died in wars and the details about the wars. Also, among the charactersitics are his application of isnād to his history book as a muḥaddith, his knowledge for the previous resources via his teachers who belong to the schools of al-Madīna and ʿIrāḳ and when required, his usage of ayah, ḥadīth and poems. These issues are dealed in the artcile with examples. Besides, a study in the West about Khalīfa b. Khayyātasserts that he was a follower of Umayyad dynasty and so this affected his historiography. In this article, this assertion is tackled by analyzing the whole book and it concludes that it is not valid because of some narrations against this assertion.SummaryKhalīfa b. Khayyāt (d. 240 / 854-55), who grew up in Basra, one of the most important centers of scholarship of the time and the meeting point of scholars, and he continued his scholarly works in this city. Since his grandfather and father are engaged in the field of Ḥadīth, Khalīfa b. Khayyāt started his scholarly adventure at an early age and he took his first education in the field of Ḥadīth.Scholars, in the early periods, continued their studies in the fields of sciences related to each other. Khalīfa b. Khayyāt’s studies are also in this kind. Although there are references in sources to his accumulation of Ḥadīth, Khalīfa b. Khayyāt ’s main area of ​​expertise is history and nasab/genealogy. The fact that his works and references to him in later sources are largely related to historical events, knowledge of the nasab/genealogy, and wafayāt (death dates of Ḥadīth scholars and narrators) reveals his considerable knowledge on these issues. Khalīfa b. Khayyāt lived in the period of ʿAbbāsid caliphs al-Maʾmūn (813-833) and al-Muʿtaṣim (833-842). This period is important because of the fact that the al-Mihna incident took place and the pressure on the Ḥadīth scholars increased. Although Khalīfa b. Khayyāt is not one of the direct opponents of Muʿtazila, his participation in a debate against them provides clues about the place where he stands. The scholarly atmosphere of Basra, enabled Khalīfa b. Khayyāt to benefit from a wide range of teacher-student network. In addition to his professors from whom he benefitted in the field of Ḥadīth, he had the opportunity to obtain the knowledge and understanding of the history of that time through his teachers who are important historians of the period in his field. Two works related to Khalīfa b. Khayyāt whose reliability is confirmed by djarh wa l tadil scholars reached to our time. One of the oldest Ṭabaḳāt works in the history of Islam is al-Ṭabaḳāt; the other one is the book, al-Taʾrīkh, which provides a new method for Islamic historiography.This study deals with the principles of the method of historiography, which can be put forward through Khalīfa b. Khayyāt 's al-Taʾrīkh. al-Taʾrīkhis important in terms of being the first example of chronological writing type in Islamic historiography and has not been subject to any independent study to date. There are two ongoing M.A. thesis about Khalīfa b. Khayyāt, however, no study has been identified that directly deals with its methodology of history. On the other hand, based on some riwāyats/narrations in al-Taʾrīkh, there is a work that claims that Khalīfa b. Khayyāt had sympathy towards Umayyads. The study named “Khalīfa b. Khayyāt’s History on the Umayyad Dynasty (660-750), prepared by Carl Wurtzel as his PhD. Dissertation, examined the life of Khalīfa, partly the historiography and the religious-political narrations in the work. On the case of Muʿāwiya’s (d. 60/680) request of the allegiance to Yazīd (d. 64/683), Wurtzel compared an event that took place between the envoy of Ibn al-Zubayr (d. 73/692) and Muʿāwiya with al-Balādhurī’s (d. 279/892-93) narrative and concluded that Khalīfa was an Umayyad sympathizer. However, Khalīfa b. Khayyāt’s exclusion of an event such as al-Mihna which was against the ʿAbbāsid and changed the course of history in his book, shouldn’t be considered as a symptom of sympathy; It would be more appropriate to accept it as a feature of history writing.At the top of Khalīfa b. Khayyāt's principles of historiography, adopting chronological method comes first. Accordingly, Khalīfa b. Khayyāt, gives a brief history about the siyar of the Prophet Muhammad at the introduction of the book. Then, by beginning from the first hijri year, he gives the important events, wars and deaths by the years. Sometimes, he refers to the people assigned by the caliphs of the period by referring to the Amîrs (Administrators) of the Hajj. He gives lists of those who died on both sides of the wars. The importance of mentioning the tribes of the deceased shows his competence in the knowledge of nasab. One of the highlights of his historiography is that he sometimes does not touch upon some of the events and situations that are considered to be turning points in Islamic history; and sometimes he does not go down into detail but just gives relevant narratives. For example, he doesn’t mention any narrations about the selection of the Caliph which perhaps the most fundamental point of separation between Ahl al-Sunnah and Shīʿa in the history of Islam.Although he gave detailed information about The Battle of The Camel (36/656) and Ṣiffīn cases (37/657), it is not possible to determine his views on this subject. In addition, he never mentioned the al-Mihna incident, which deeply influenced society and the scholarly environment during the ʿAbbāsid period. Isnād is also holds an important place in the methodology of history of Khalīfa who was a muḥaddith at the same time. In many of the narrations he used the words haddathanā and ahbaranā.In our study, the siyar section of al-Taʾrīkhwas examined in order to determine the sources of the Khalīfa’s historiography and has been seen that the works of Ibn Isḥāḳ (d. 151/768) and Ibn Hishām (d. 218/833) were the main sources of this chapter. Considering Khalīfa b. Khayyāt’s emphasize to isnād and his reach to Ibn Isḥāḳ 's work through the mediation of Bekr b. Suleiman, it can be said that he was dominant in historiography on the sources before him. Khalīfa b. Khayyāt rarely refers to Qur’anic verses and hadiths when describing events. He referred to the verses in only two places and hadiths in only five places. One of them, and perhaps the most remarkable one in the book is the Ḥadīth of the Prophet Muḥammad: “I am the guardian of whom; ‘Alī is his guardian” This narration is used in the letter of Caliph Mahdī (d. 169/785) of the ʿAbbāsid to khārijī (outer) Abd al-Salām b. Hishām who rebelled. The study is based on the principles outlined above. At the end of the study it is also considered that Khalīfa b. Khayyāt ’s works should be the subject of graduate studies which should be prepared with deep readings. (shrink)

Some people change dramatically over time, and often those changes result partly from what they have chosen to do for a living. Drawing on the work of Richard Sennett and Sandeep Jauhar, I explore how practicing in a market-driven medical system can corrupt the character of doctors.

_Psychological Types_ is one of Jung's most important and most famous works. First published by Routledge in the early 1920s it appeared after Jung's so-called fallow period, during which he published little, and it is perhaps the first significant book to appear after his own confrontation with the unconscious. It is the book that introduced the world to the terms 'extravert' and 'introvert'. Though very much associated with the unconscious, in _Psychological Types_ Jung shows himself to be a supreme theorist (...) of the conscious. In putting forward his system of psychological types Jung provides a means for understanding ourselves and the world around us: our different patterns of behaviour, our relationships, marriage, national and international conflict, organizational functioning. Appearing in paperback for the first time this central volume from Jung's Collected Works will be essential to anyone requiring a proper understanding of Jung's psychology. (shrink)

Naturalistic experiments of color perception are critically evaluated. The review concludes that they fail to confirm a natural determination of color perception. Rather than demonstrating universal sensitivity to focal colors, the experiments actually yielded enormous cultural variation in response. This variation is interpreted as supporting a sociohistorical psychological explanation of color perception.

Foundationalist, Coherentist, Skeptic etc., have all been united in one respect--all accept epistemic justification cannot result from an unending, and non-repeating, chain of reasons. Peter Klein has recently challenged this minimal consensus with a defense of what he calls "Infinitism"--the position that justification can result from such a regress. Klein provides surprisingly convincing responses to most of the common objections to Infinitism, but I will argue that he fails to address a venerable metaphysical concern about a certain type of regress. (...) My conclusion will be that until Klein answers these metaphysical worries he will not have restored Infinitism as a viable option in epistemology. (shrink)

We initiate the reverse mathematics of general topology. We show that a certain metrization theorem is equivalent to Π2 1 comprehension. An MF space is defined to be a topological space of the form MF(P) with the topology generated by $\lbrace N_p \mid p \in P \rbrace$ . Here P is a poset, MF(P) is the set of maximal filters on P, and $N_p = \lbrace F \in MF(P) \mid p \in F \rbrace$ . If the poset P is countable, (...) the space MF(P) is said to be countably based. The class of countably based MF spaces can be defined and discussed within the subsystem ACA0 of second order arithmetic. One can prove within ACA0 that every complete separable metric space is homeomorphic to a countably based MF space which is regular. We show that the converse statement, "every countably based MF space which is regular is homeomorphic to a complete separable metric space," is equivalent to Π2 1-CA0. The equivalence is proved in the weaker system Π1 1-CA0. This is the first example of a theorem of core mathematics which is provable in second order arithmetic and implies Π2 1 comprehension.

This article is based on an ethnographic investigation of the Gezi Park events in 2013. Starting from the much acknowledged characteristics of Gezi as being its cultural and political pluralism and its commitment to non-violence, in this article we are engaging with two interlinked questions: How has the plurality of participants and orientations been possible to attain, and how could this pluralism be contained without any major conflict at Gezi? We propose to provide an answer by focusing on the manners (...) of everyday life at Gezi Park during the time of dissidence, which we conceptualize as ‘manner of contention’. It was the manner of contention that characterized the specific ways in which contentious politics took place at Gezi and prevented the formation of clashes among the plurality of contenders. The ethnographic research delineates at least 4 components of manner of contention in the case of Gezi: an ethos of collective work; a spirit of exchange and gift-giving; politeness; and non-violence.

1. Object of this note . In his lively essay, “Between Analytic and Empirical,” , Mr. J. W. N. Watkins challenges the empiricist identification of synthetic statements with empirical ones by arguing that there exists an important class of statements which are synthetic, i.e. not analytically true or false, and yet not empirical. I find Mr. Watkins's arguments very stimulating, but I do not think they provide a sound basis for his contention. In the present note, I wish to indicate (...) what seem to me the principal flaws in Mr. Watkins's reasoning, and to make some additional comments on the issues raised by his discussion. (shrink)

Richard Jeffrey’s “Conditioning, Kinematics, and Exchangeability” is one of the foundational documents of probability kinematics. However, the section entitled “Successive Updating” contains a subtle error regarding the applicability of updating by so-called relevance quotients in order to ensure the commutativity of successive probability kinematical revisions. Upon becoming aware of this error, Jeffrey formulated the appropriate remedy, but he never discussed the issue in print. To head off any confusion, it seems worthwhile to alert readers of Jeffrey’s “Conditioning, Kinematics, and Exchangeability” (...) to the aforementioned error and to document his remedy, placing it in the context of both earlier and subsequent work on commuting probability kinematical revisions.1.

In this paper I discuss the possibility of the idea of emancipation within an educational philosophy that does not accept schooling as its first premise. The first part of the paper will take Sweden as an example of an educational state defined through educational policies such as life long learning, accountability and evidence-based research, and argue that these words are only meaningful within the myth of schooling and not in a language of education/emancipation. The second part of the paper discusses (...) different but related conceptions of emancipation by exploring its ambiguous nature. In the third part of the paper I specify the role and place of emancipation within a philosophy of education that seeks to articulate its social value. (shrink)

Hirschfeldt and Shore have introduced a notion of stability for infinite posets. We define an arguably more natural notion called weak stability, and we study the existence of infinite computable or low chains or antichains, and of infinite $\Pi _1^0 $ chains and antichains, in infinite computable stable and weakly stable posets. For example, we extend a result of Hirschfeldt and Shore to show that every infinite computable weakly stable poset contains either an infinite low chain or an infinite computable (...) antichain. Our hardest result is that there is an infinite computable weakly stable poset with no infinite $\Pi _1^0 $ chains or antichains. On the other hand, it is easily seen that every infinite computable stable poset contains an infinite computable chain or an infinite $\Pi _1^0 $ antichain. In Reverse Mathematics, we show that SCAC, the principle that every infinite stable poset contains an infinite chain or antichain, is equivalent over RCA₀ to WSCAC, the corresponding principle for weakly stable posets.

Kant says patently conflicting things about infinity and our grasp of it. Infinite space is a good case in point. In his solution to the First Antinomy, he denies that we can grasp the spatial universe as infinite, and therefore that this universe can be infinite; while in the Aesthetic he says just the opposite: ‘Space is represented as a given infinite magnitude’ (A25/B39). And he rests these upon consistently opposite grounds. In the Antinomy we are told that we can (...) have no intuitive grasp of an infinite space, and in the Aesthetic he says that our grasp of infinite space is precisely intuitive. (shrink)
