Al-Ash'ari

Abu al-Hasan al-Ash'ari spent years trained inside Mu'tazilite theology, the rationalist school that subordinated the plain sense of scripture to reasoned argument, before publicly breaking with it in his own maturity in Basra and later Baghdad. Rather than simply reverting to the literalism Mu'tazilite theology had itself reacted against, he built a documented third position between the two extremes his own career had passed through.

That position, later known as Ash'ari theology, affirmed the divine attributes scripture describes, such as God's hands or God sitting on a throne, as real rather than metaphorical, while refusing to specify how such attributes apply to a being scripture itself calls incomparable. The doctrine became known as bila kayfa, without asking how, and it let al-Ash'ari go on using the same rational argument his Mu'tazilite training had taught him, now turned toward defending scripture's claims rather than subordinating them to reason.

That a theologian who spent his early career trained inside the school he eventually broke with built his alternative by redirecting that same rational method rather than discarding it marks al-Ash'ari's break as a documented case of a rationalist tradition's own method outliving the rationalist conclusions it had been trained to reach.

Ash'ari theology did not remain one ninth century theologian's personal resolution of a dispute between rationalism and literalism. In the centuries after Abu al-Hasan al-Ash'ari's death in 936, it became the dominant kalam, theological, school across most of the historical Sunni world, a documented spread rather than a position that stayed confined to the city where he taught.

Two of the four Sunni legal traditions, the Shafi'i and Maliki schools, adopted Ash'ari theology as their doctrinal framework, pairing his middle course between Mu'tazilite rationalism and strict literalism with their own legal methods. Later theologians, including al-Baqillani and al-Juwayni, codified and extended his positions further, building an institutional and scholarly tradition on top of the bila kayfa doctrine rather than leaving it as a single thinker's own formulation.

That a theological position formed by one scholar's break with his own rationalist training went on to become the doctrinal framework adopted by two of Sunni Islam's four legal schools and elaborated by generations of later theologians marks Ash'ari theology's spread as a documented case of a single scholar's resolution outgrowing its own originator by a wide historical margin.
