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)

The historian Agathias (Hist. II 30.3-31.4) relates that under the Emperor Justinian seven philosophers (Damascius, Simplicius, Eulamius, Priscianus, Hermeias, Diogenes, and Isidorus) sought refuge in Persia because of their own country's anti-pagan laws but that they ultimately returned in 532 to the Roman Empire. There have been many hypotheses about the fate of these philosophers after their return. Most recently M. Tardieu has argued that these philosophers went to Harran, a town that was located on the Persian frontier and that (...) remained mostly pagan until the tenth century. This hypothesis, which M. Tardieu had backed with a number of arguments, has found many echoes, both positive and negative, in subsequent secondary literature. Yet the complexity of the issue has never really been faced by Tardieu's critics. For example, the fact that, according to Arab sources, Simplicius could found a famous school of mathematics has been completely neglected, as has the fact that details of the dogmas of Manicheanism, which he obtained through his encounter with a member of that sect, enable one to envision a Mesopotamian locale for this encounter. The present study aims at taking stock of the elements of this controversy, beginning with a detailed article by D. Watts and a review by C. Luna. Watts mostly bases his criticisms of M. Tardieu and me on Luna's summary. In the conclusion (pages 58-59), I summarize the main points that seem to me to confirm M. Tardieu's hypothesis. (shrink)

This piece of work intends to shed light on Alexander of Aphrodisias from the second-century Aristotle commentator through the history of Aristotelian psychology up to the sixteenth century's clandestine prompter of the new philosophy of nature. In the millennium after his death the head of the Peripatetic school in Athens served as the authority on Aristotle in the Neo-Platonic school, survived the Arabic centuries of philosophy as Averroes' exemplary exponent of the mortality of the soul and as such was not (...) considered worthy of translation by the Latin Scholastics. This attitude changed only in the Late Middle Ages, when the resistance against Averroes grew fierce and Alexander emerged as the only Aristotelian alternative to him. In 1495 his account of Aristotle's psychology was translated and published and the underlying principles of a natural philosophy, based on sense perception and exempt from metaphysics, became accessible. The prompt reception and widespread endorsement of Alexander's teaching testify to his impact throughout the sixteenth century. (shrink)

Love has been present in several manifestations in that Islamic thought has been expressed. Avicena wrote a Treatise on Love that has been considered as a mystic writing. An attentive reading of this work shows that its content is not mystic neither gnostic, but it rather agrees with the Avicenna’s philosophical doctrines exposed on other of his most important works. The content of that Treatise is described on this paper.
