Abstract
This study examines the influence of Qur'anic teachings on the development of falsafa on the one hand, and the position of tafsirs in the intellectual history of Islam on the other. To do so, in the introduction it attempts to situate the place of falsafa and its connections with kalam and tafsir, and to explain the approach that will be followed in this research. In the first part it treats some of the ontological vocabulary of the Qur'an, while in the second, it concentrates on the questions raised by the Qur'an about the ontological status of pre-existing things as well as on the notions of creation and existence. To this purpose it surveys some early tafsirs in order to see how the debate over these issues evolved therein and how philosophical discussions were appropriated and naturalized by the mufassirun.
