The theologian who turned against his own teachers to argue that reason must serve revelation, founding the school that became Sunni orthodoxy.
Al-Ash'ari trained among the Mu'tazila, the rationalist theologians who made reason the measure of faith, then broke with them at forty in a public reversal. God's will, he argued, is not bound by our logic; the world holds together only because God recreates it at every instant, so that fire does not burn by its own nature but because God wills the burning. Reason has its place, but as the servant of revelation, not its judge. His middle path between blind literalism and unchecked rationalism became the dominant theology of Sunni Islam.
“Fire does not burn by its own nature, but because God wills the burning at every instant.”
Born in Basra and trained among the rationalist Mu'tazila theologians.
Renounced the Mu'tazila in a public reversal and founded the theology that would become Sunni orthodoxy.
Al-Ghazali worked within, and brought to its height, the Ash'ari theology that al-Ash'ari had founded.
