This site makes available the original Arabic (also Persian and Syriac) for the passages translated in the open access book series "The Heirs of Avicenna: Philosophy in the Islamic East, 12-13th Centuries." 

The passages have been transcribed from the printed editions and manuscripts cited in these volumes, and are arranged thematically in correspondence with the chapters in the volumes. Each link below will lead you to a PDF of the passages in their original languages. This is a free resource and may be used for all teaching and research purposes.

Note that we are still in the process of finalizing and uploading the PDFs; we aim to have them online completely as soon as possible.

The "Heirs of Avicenna" volumes and this online resource were made possible by the support of the Deutsche Forschungsgemeinschaft (DFG). The project (DFG number: 273594864) was led by Peter Adamson, Professor of Philosophy at the LMU in Munich. He worked in conjunction with a team of postdoctoral researchers including Fedor Benevich, Dustin Klinger, Michael Noble, and Sarah Virgi. Additional material was provided by Salimeh Maghsoudlou, Alex Kalbarczyk, Nora Kalbarczyk, Hassan Rezakhany, Francesco Zamboni, and Saleh Zarepour. The transcriptions themselves were done by Nada Abdelsalam, Hanif Amin Beidokhti, Michael Lessman, and Abdurrahman Mihirig. We would also like to thank the project advisory board: Khaled El-Rouayheb, Heidrun Eichner, Frank Griffel, Judith Pfeiffer, Reza Pourjavady, Mohammed Rustom, Gregor Schwarb, Ayman Shihadeh, Tony Street, and Robert Wisnovsky.

Riccardo Strobino has kindly prepared this interactive map of Fakhr al-Dīn al-Rāzī's Manṭiq al-Mulakhkhaṣ, a major and influential work of logic from the period covered in the Heirs of Avicenna. This resource also provides additional information to go along with Prof Strobino's contribution to P. Adamson and D. Janos (eds), Interpreting Fakhr al-Dīn al-Rāzī: Critical Essays, published by Cambridge University Press (2027). By navigating through this map you can get a good sense of how logical works of the period were structured and what issues they covered.
