The Asharites and the Mortasilites

The basta school held that whoever is capable of knowledge of god becomes an unbeliever if he does not apply knowledge to no god. The more demanding attitude of the mortasilites, who wanted all believers to engage in what we might call an ijtihad of theological reflection, was taken up by al ashari. In their strictures against talid, the main concern of the asherites was that believers should be free of uncertainty. But on the subject of takli, the asharites are remarkably rationalists too.
