A Study of Nasir al-Din Tusi's Meditations on Ethics

Many researchers believe that Averrors is the last philosopher in intellectual history of Islamic civilization. Therefore they did not pay attention to rational heritage in Shiism. Whereas Shiite world was the more paradigm of Islamic intellectual life in philosophy and sciences, but was neglected. This neglection caused the decline theory and thought in Islamic world post 615(AH).This discourse engaged to explain and prove the invalidity of the theory by researching in Nasirodin's role in renewed birth of intellectual life in seventh century. His efforts in philosophy and ethics in the decadence period should be significant.Scientific research will prove Nasirodin's prominence in emerging intelectual schools (Shiraz, Isfehan and Tehran). Akhlaghe Naseri is the first and most important work of him in ethics science. He compiled it as an independent work, considering his reasoning that Tahzib-al-Achlagh has some deficiency, particular in demostic economy and politics. Three fundamental subjects are researched in Akhlaghe Naseri: knowledge of self (Rational faculty), virtues and prosperity, and justice. He believes that prosperity is subject and ultimate object of ethics. This believe caused him to allocate most part of first chapter in pondering salvation sense, perfect and deficiency of nous, and finally good deeds and self-knowledge. His critique on Aristotle and Averroes in counting virtues species and describing rascalities kinds basis on Quranic thoughts, is distinguished.
