Reason and Revelation

Abu Yusuf al-Kindi (c. 801–873 CE) was the first major Islamic philosopher and one of the most wide-ranging minds of the Abbasid era. Working at Baghdad's House of Wisdom, he pioneered the synthesis of Greek philosophy with Islamic thought across many sciences.

Ibn Rushd (1126-1198 CE), known in the West as Averroes, was one of the most influential philosophers in Islamic history, whose commentaries on Aristotle profoundly shaped both Islamic philosophy and medieval European scholasticism, bridging Eastern and Western intellectual traditions.

The Mu'tazilite school of Islamic theology gives priority to reason in interpreting matters of belief. It emerged in Basra in the early eighth century, was the official doctrine of the Abbasid state under al-Ma'mun and his two successors, and set out its theology under five principles.
