The Philosophical Conflict between the School of Baghdad and the School of Khorasan in the Tenth Century: Towards a New Understanding of the Development of Islamic Philosophy

Historians often present the evolution of Islamic philosophy through a limited number of philosophers beginning with al-Kindī and concluding with Ibn Rushd. This practice tacitly asserts that Islamic philosophy developed only in accordance with this “sequential” or “chronological” context that assumes it was the inevitable evolution of Aristotelian thought in Arabic. However, most of those who present Islamic philosophy in this manner appear to have overlooked the fact that it developed in the context of a philosophical conflict that emerged between the two schools to which the majority of Islamic philosophers belonged – the School of Baghdad and the School of Khorasan, which appeared in the tenth century and introduced philosophy to Islam and Muslims. This study stands apart from earlier attempts to present Islamic philosophy by considering these two schools and the frequently violent disputes that occurred between them. It is based on an historical-analytical approach accompanied by a rereading of numerous historical and literary texts and presents a reinterpretation of the works of Ibn Sīnā that differs from past interpretations of the history of Islamic philosophy. The study concludes with a thorough examination of the texts and contexts, which demonstrates the existence of the two philosophical schools and their significant contributions to the development of Islamic philosophy, albeit with their own distinctive elements. The study also argues that the philosophical School of Baghdad migrated to Morocco and Andalusia and arrived, in some respects, in Europe through Ibn Rushd, whereas the School of Khorasan appeared in Suhrawardī’s Philosophy of Illumination and in modern Iranian philosophy.     

Mumford on aesthetic–moral interaction in sport

Stephen Mumford argues that aesthetic and moral values in sport are interdependent, focusing on cases where immorality taints beautiful performance. This interdependence thesis is insightful but, I argue, in need of refinement, as its normative implications are unclear and perhaps implausible (e.g. the Nazi aesthetics problem). I also challenge Mumford’s perspective on the infamous Dynamo Kiev death match. Whereas Mumford claims that the match’s morally oppressive circumstances detract from it so that ‘it was not something knowingly we should have admired aesthetically’, I argue that, on the contrary, and in light of what Mumford says about other cases, such circumstances actually enhance the game’s aesthetics such that it would be wrong not to appreciate it aesthetically.     

Long-term endurance training increases serum cathepsin S and decreases IL-6 and hsCRP levels

Cathepsin S (CS) was shown to play a key role in cancer progression, atherosclerosis, heart valve disease, insulin resistance and diabetes mellitus. The present prospective study aimed to investigate the influence of sports on CS, interleukin-6 (Il-6) and high-sensitivity C-reactive protein (hsCRP) levels.

Ninety-eight of 109 participants completed the study. Ergometries were performed at baseline and after 8 months to evaluate/quantify the performance gain. Blood samples were taken at baseline and every 2 months. CS was measured by ELISA (enzyme-linked immunosorbent assay). Compared to the control group (mean performance gain ?3.41 ± 4.62%) we observed a significant physical-activity-induced increase of CS levels (3.45–3.73 ng · ml^?1; P = 0.027) and a significant decrease of Il-6 (2.43–1.91 pg · ml^?1; P = 0.031) and hsCRP-levels (0.11–0.09 mg · dl^?1; P = 0.001) in the intervention group (mean performance gain: 12.13 ± 6.32%). Furthermore, the tendency of the progression was significant for CS and Il-6 (P = 0.002/0.033).

We could show a significant sports-induced decrease of the classic inflammation parameters hsCRP/Il-6, probably expressing a downregulation of permanently prevalent inflammation processes. Simultaneously CS levels increased significantly. Our results show that increasing CS amounts are not simply to equal with an enhanced inflammation status and might even have beneficial effects on inflammation and angiogenesis.
