Having got to know the peripatetic philosophy on the basis of Ibn Rushd's and Ibn Sina's Commentary, of the Aristotelian philosophy, Thomas proceeded to establish a Christian philosophical system. In spite of taking much advantage of Ibn Sina, Thomas disagreed with some of Ibn Sina's philosophical opinions and attempted to criticize them, due to al-Gazali's criticisms on philosophy. One case of the disagreement is the question of coming-into-being and eternity of the world. The present paper is going to evaluate Ibn Sina's and Aquinas's views and to make it clear that Aquinas's objections are deficient, and that his responses fail to be convincing.   Ibn sina and Thomas Aquinas, two prominent figures in Muslim and Christian worlds, are among the most influential philosophers in medieval ages.
