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.
