The Muʿtazila — Rational Theology

The Muʿtazila were the pioneers of rational theology in Islam, exalting reason and divine justice — briefly the state creed under the ʿAbbāsids.

At a glance

Emerging in the 8th century amid debates with dualists, Christians and others, the Muʿtazila built the first systematic rational theology in Islam around two watchwords: God's absolute unity and His absolute justice. From unity they argued that God's attributes could not be eternal realities alongside His essence, lest they compromise His oneness. From justice they argued that human beings must be truly free, for a just God could not punish acts He had compelled, and that reason, independent of revelation, could discern good and evil.

They also held the Qur'an to be created rather than co-eternal with God. In the early 9th century the caliph al-Maʾmūn raised this doctrine to the status of state creed and enforced it through an inquisition (the miḥna); the traditionist Aḥmad ibn Ḥanbal famously endured persecution rather than affirm it. The episode discredited the movement's coercive turn, and a reaction set in that produced Sunni orthodox theology.

Though the Muʿtazila declined as a distinct school, their questions and methods permanently shaped Islamic theology, and something of their rationalism survived within Twelver Shiʿi thought.
