“An Inquiry into Philosophical Disagreements of Nasīr al-Dīn al-Tusī with Ibn Sīnā “

The philosophy of Islam is the starting point for Islamic philosophy, which was initiated by Kenndī and expanded by Fārābī, completing it by Ibn Sīnā and adding many topics to it, and later by theologians such as Fakhr Razi, Imam Mohammad Ghazāli and Mohammad bin Abdul Karīm Shahrestānī were confronted several clashes and it was going to collapse of its pillars, but with renewed defenses of Khajeh Nāsīr, it was possible to flourish itself and spread the true philosophy; through the defense of this kind of philosophy  by him it did not confine itself to this school, and, wherever it was opposed to the Jews and the philosophy of Ibn Sīnā, (apart from the explanation of the references), refrained from expressing it. This treatise expresses the philosophical differences between Khajeh and Ibn- Sīnā in a blurred way; whether there are differences in natural or in theology; but the logical differences and practical wisdom between these two unbelievers, needs separate study, and a  thorough treatise.
