Movements and eternity of the world in Arab and Latin philosophy
Session organized by Charles Ehret & Miriam Rogasch
The eternity of the world, before being a theological question, is a physical question, anchored in a conception of the movement where each change presupposes, upstream, a prerequisite and extends, downstream, towards a subsequent movement. The central link in this sequence is generation, the advent of a substantial form in which everything ends and where everything begins again. It is thus a question of questioning, from the perspective of a world whose eternity is questioned, the relation between, on the one hand, all the movements that make up the generation and, on the other hand, the set of natural movements that derive from the substantial form (elementary movements, vital operations, intellective processes). Can we speak in both cases of "movement" in an unambiguous sense? Are the movements that flow from the form oriented towards a later form that would call into question the substantiality of the first? Do these movements lead to the understanding of the substantial form as a principle of movement, that is, a power? Lastly, and above all, does the sequence of these movements make it possible to affirm or, on the contrary, to invalidate the eternity of the course of the world?

Zeinab Karimian (Univ. Paris Diderot, SPHERE)
Al-Ṭūsī and his recensions of mathematical textbooks
A considerable amount of al-Ṭūsī’s mathematical works consists of his recensions on the mathematical treatises which were circulated among the scholars of his time and before. These mathematical textbooks included of Arabic translations of several Greek texts – known as Intermediate or Middle Books (Kutub al-Mutawassiṭāt) – as well as some of the mathematical works of medieval Islam. Several copies of al-Mutawassiṭāt, until 19th century, indicate the popularity and significance of these recensions. In this paper, I will discuss the importance of al-Ṭūsī’s project, his aims, the complexity of the issues he dealt with, etc. I will also try to examine to what extent these recensions were close to the original texts and to explain the general aspects of these recensions.

- 12:00 – 13:00
Hossein Masoumi Hamedani (University of Teheran)
Naṣīr al-Dīn al-Ṭūsī and the history of spherical trigonometry
The development of spherical trigonometry, as an independent discipline, is generally considered as one of the main mathematical achievements of classical Islam. This development began by the simultaneous discovery of the sine law by several mathematicians in the tenth century, and the priority debate which arouse in this regard bears witness to the importance mathematicians attributed to this discovery. Al-Ṭūsī’s redaction of Unveiling the Secrets of the Setor Theorem, both in Arabic and Persian, can be seen as a decisive stage in this development. In this article the main characteristics of this work, its structure and content, and the relations between its Arabic and Persian versions are discussed and its role in the coming of age of spherical trigonometry is explained.
