The purpose of this article is to discuss Safavid period Islamic philosopher Sadraddin Shirazi’s philosophical methodology and the sources of the school founded by him. The article relies on research conducted on Shirazi philosophy. It shows that Shirazi through synthesizing the methods of the earlier schools that existed in Islam to acquire knowledge devised a new mechanism for acquiring knowledge. Before coming to Shirazi, intellectual movements formed during Islam’s classical period, such as peripateticism, illuminationism, theology and Gnosticism, were of (...) different views regarding the best way to reach the truth. For example, for peripatetics reason, for theologians revelation, for gnostics/mystics intuition or personal experience were important, but ishraqi school was somewhere between peripatetic and Gnostic schools. Sadraddin Shirazi, though, considered all these agents necessary, for they complement each other, and said they should be utilized altogether to obtain ultimate reality. Similarly, considering his philosophical sources, we see that he is influenced almost by all philosophical schools as well as religious sources. However, Ibn Sina and Ibn Arabi’s influence on him was more profound compared to other philosophers. (shrink)

Shahāb ad-Dīn" Yahya ibn Habash ibn Amirak as-Suhrawardī, (also Shaikh al-Ishraq, Shaikh al-Maqtul) was founder of the illuminationist school (Ar. Hikmat al-ishraq; Pers. falsafaye ešrāqi ). Derived from “illumination,” a conventional translation of the Arabic term ishraq (lit. radiance, shining of the rising sun), “illuminationism” refers to the doctrine of the Ishraqiyyun, a school of philosophical and mystical thought of various Graeco-Oriental roots whose principles were propounded as an ancient “science of lights” (‘ilm al-anwar) . He chose this title (...) to distinguish his philosophical theory from mashshaī's philosophy; and he is one of the first philosophers to elaborate on an old tradition. His approach Adopted from Zoroastrian and Platonic ideas. In fact, he associates his science of lights principally with the names of Plato, Hermes, Empedokles, Pythagoras, and the ‘Oriental principle concerning light and darkness’ of the sages of ancient Iran.
