Throughout the history of human thought, societies have been influenced by the ideas of previous cultures and civilizations. Some interactions have taken the form of the transmission of ideas and traditions through travel, such as the information contained in the works of Biruni (d. 1061) based on his observations during his journey to India. In addition, civilizations have influenced each other through wars and conquests. The greatest example of this is Hellenism, which emerged with Alexander the Great's (356-323 BC) Eastern campaign and influenced both Eastern and Western thought, or the adoption of ideas encountered by Islamic armies as a result of their conquests of Iran and Anatolia. Furthermore, the ideas and traditions of those who later converted to Islam and brought some of their ideas with them are another example of this interaction. Besides these, translations of scientific and philosophical books, which constitute the subject of our study, also play a significant role in the transmission of ideas and civilizations. The translation movement should not be perceived solely as benefiting from the scientific accumulation of a single nation or the heritage of a particular culture or civilization. Indeed, the translation movements of philosophical and other scientific disciplines that began in the Islamic world encompassed multiple different cultures and civilizations (such as Greek, Iranian, and Indian). In our study focusing on Iranian thought and its transmission through Persian during the translation period, we will briefly examine how philosophical translations were transferred to the Islamic world. Although Arabic was the predominantly scientific language during the translation period, it is known that Persian was also used in philosophical and literary works, and that there was interaction with philosophical sources translated from this language. While the Persian language may racially suggest Persian origins, the scientific and philosophical works produced in this language reflect the culture, civilization, and intellectual world of other nations living in the aforementioned geographical area. It should not be forgotten that multiple nations lived in the region known as the Iranian geographical area, and these groups also used the Persian language. In this context, our study, which examines Islamic philosophy within the framework of Iranian thought and the philosophical tradition transmitted through Persian—one of the languages, cultures, and civilizations that influenced its emergence—will only briefly touch upon the subject due to limitations preventing us from reviewing the entire literature.
