ナスィールッディーン・トゥースィー
At the end of thirteen century, Nasir al-Din al-Tusi wrote this book when he was in Quhistan to response to request of Nasir al-Din Abu al-Fath Abd al-Rahim ibn Abi Mansur, a Nizari Ismaili governor, for translating a famous Arabic book, Tahdhib al-Akhlaq, that was written by Miskawayh. The Miskawayh's book was about ethics but Nasir al-Din al-Tusi added the parts of domestic economy and politics of his work.
