Liber de Causis (The Book of Causes)

Arabists attribute the text to an anonymous author who lived during the 9th or 10th century and who worked in the cultural milieu that radiated from Baghdad. Possibly the author worked at the center for translation of Greek works into Arabic and Syriac founded in 832 by Caliph al-Ma'mum. 12. Historical note on the House of Wisdom in Baghdad. Included among the Arabists are: Bardenhewer, 13. Kraus, 14. d'Alverny, 15. Walzer, 16. Anawati, 17. Saffrey, 18. and Badawi. 19. Since no Arab author before the 12th century mentions the Liber, the Latinists are convinced that the treatise did not spring from Eastern soil. Rather, they assign the origins of the De causis to one of the two frontiers between the Latin and Arab worlds: most probably Spain and in particular Toledo, where it was translated, or possibly the Kingdom of Sicily. Among the Latinists (and those who are expert in the Hebrew tradition) are: Steinschneider, 20. Kaufmann, 21. Guttmann, 22. Duhem, 23. Alónso, 24. and Pattin. 25.
