We are now in a position to finish shortly with the Mu‘tazilites. Their work, as a constructive force, is done. From this time on there is _kalam_ among the orthodox, and the term _mutakallim_ denotes nothing but a scholastic theologian, whether of one wing or another. And so, like any other organ which has done its part and for the existence of which there is no longer any object, they gradually and quietly dropped into the background. They had still, sometimes, to suffer persecution, and for hundreds of years there were men who continued to call themselves Mu‘tazilites; but their heresies came to be heresies of the schools and not burning questions in the eyes of the masses. We need now draw attention to only a few incidents and figures in this dying movement. The Muslim historians lay much stress on the orthodox zeal of the Khalifa al-Qadir, who reigned 381-422, and narrate how he persecuted the Mu‘tazilites, Shi‘ites and other heretics and compelled them, under oath, to conform. But there are several difficulties in the way of this persecution, which make it probable that it was more nominal than otherwise. Al-Qadir was bitterly orthodox; he had written a treatise on theology and compelled his unhappy courtiers to listen to a public reading of it every week. But he enjoyed, outside of his palace, next to no power. He was in the control of the Shi‘ite Buwayhids, who, as we have seen, ruled Baghdad and the Khalifate from 320 to 447. These dubious persecutions are said to have fallen in 408 and 420. Again, a Muslim pilgrim from Spain visited Baghdad about 390 and has left us a record of the state of religious things there. He found in session what may perhaps best be described as a Parliament of Religions. It seems to have been a free debate between Muslims of all sects, orthodox and heretical, Parsees and atheists, Jews and Christians—unbelievers of every kind. Each party had a spokesman, and at the beginning of the proceedings the rule was rehearsed that no one might appeal to the sacred books of his creed but might only adduce arguments founded upon reason. The pious Spanish Muslim went to two meetings but did not peril his soul by any further visits. In his narrative we recognize the horror with which the orthodox of Spain viewed such proceedings—Spain, Muslim and Christian, has always favored the straitest sect; but when such a thing was permitted in Baghdad, religious liberty there at least must have been tolerably broad. Possibly it was sittings of the _Ikhwan as-safa_ upon which this scandalized Spaniard stumbled. He himself speaks of them as meetings of mutakallims. [Sidenote: MAHMUD OF GHAZNA]
