As the scholasticism of Islam, the kaliim manifests itself as pure rational dialectic which operates upon the concepts of theology. We are dealing neither with mystical gnosis ('irian), nor with the 'science of the heart' of which the Shiite hnams were the first to speak. Moreover, as the philosophers al-Farabi and Averroes, as well as Mulla Sadra al-Shirazr, have emphasized, the mutakallimtin are above all apologists, devoted not so much to a demonstrated or demonstrable truth as to upholding, with the aid of all the resources of their theological dialectic, the articles of their traditional religious credo. Such a task is doubtless inescapable where a religious community is concerned: there was also a Shiite kalam. But the hnams were already warning their followers against any exclusive attachment to the problems and method of the kalam. This is because mystical theosophy-'irianfunctions in a manner which is. hermeneutical rather than dialectic, and keeps itself as aloof as possible from all 'intellectualism'.
