R. Saadia Ga'on, which is known to have been substantially influenced by Saadia, in fine is also indebted to Stoic philosophy and physics.

R. Saadia Ga'on (882–942) de Baghdad tâchait d'éviter l'anthropomorphisme en avançant que les versets bibliques qui semblent attribuer des traits matériels à Dieu portent non sur Dieu Lui-même, mais sur une entité créée, la Gloire de Dieu, que Saadia décrivait comme un “air” extrêmement subtil. Cet article s'efforce de montrer que la conception saadienne d'un air quasi divin, par lequel Dieu accomplit Ses actes dans le monde matériel, est redevable à la doctrine stoïcienne dupneuma. Il s'ensuit que la théologie immanentiste (...) desḤasidey Ashkenaz(Piétistes allemands), que l'on sait avoir été trés influencée par Saadia, est un prolongement lointain de la philosophic et de la physique stoïciennes.

This dissertation offers a new and comprehensive analysis of Abū Naṣr al-Fārābī's cosmology by focusing on various important issues that have been largely neglected by the modern scholarship. It provides an examination of the physical, metaphysical, and astronomical aspects of al-Fārābī's cosmology by adopting a multidisciplinary approach that takes into account the history of philosophy and the history of astronomy. Accordingly, my dissertation explores how al-Fārābī attempted to reconcile features of Ptolemaic astronomy with Aristotelian and Neoplatonic theories, an endeavor which (...) resulted in the formulation of innovative cosmological ideas. Chapters I and II provide background information on al-Fārābī's activity as a commentator and his relation to the Greek commentatorial tradition and assess the relevant primary sources. In addition, they examine al-Fārābī's approach to cosmology and his scientific method in terms of both the Ptolemaic astronomical tradition and the Aristotelian corpus. Chapter III addresses problems related to the structure of al-Fārābī's cosmology, especially the origin of his ennadic cosmological model and his spherology. Particular attention is devoted to the question of how Aristotle's unmoved movers and Ptolemy's astronomical theories are reconciled. Chapters IV, V, and VI analyze the place of celestial matter, intellect, and motion respectively in al-Fārābī's cosmology and attempt to redefine the second teacher's relation to the various trends of Greek philosophy. The study stresses al-Fārābī's connection with the Neoplatonic and Peripatetic currents, particularly with thinkers such as Alexander of Aphrod. (shrink)
