Al-Ghazzali, his life, times, and work; Sufiism formally accepted into Islam. WITH the time came the man. He was al-Ghazzali, the greatest, certainly the most sympathetic figure in the history of Islam, and the only teacher of the after generations ever put by a Muslim on a level with the four great Imams. The equal of Augustine in philosophical and theological importance, by his side the Aristotelian philosophers of Islam, Ibn Rushd and all the rest, seem beggarly compilers and scholiasts. Only al-Farabi, and that in virtue of his mysticism, approaches him. In his own person he took up the life of his time on all its sides and with it all its problems. He lived through them all and drew his theology from ms experience. Systems and classifications, words and arguments about words, he swept away; the facts of life as he had known them in his own soul he grasped. When his work was done the revelation of the mystic (kashf) was not only a full part but the basal part in the structure of Muslim theology. That basis, in spite, or rather on account of the work of the mutakallims had previously been lacking. Such a scepticism as their atomic system had practically amounted to, could disprove much but could prove little. If all the categories but substance and quality are mere subjectivities, existing in the Al-Ghazzali was born at Tus in 450. He lost his This view of the nature of the soul is essential to the Sufi position and is probably borrowed from it. But there are in it two possibilities of heresy, if the view be pushed any further. It tends (1) to destroy the important Muslim dogma of God's Difference (mukhalafa) from all created things, and (2) to maintain that the souls of men are partakers of the divine nature and will return to it at death. Al-Ghazzali labored to safeguard both dangers, but they were there and showed themselves in time. Just as the Aristotelian + neo-Platonic philosophers reached the position that the universe with all its spheres was God, so, later, Sufis came to the other pantheistic position that God was the world. Before the atomic Further, there is another side of al-Ghazzali's attitude toward the physical universe that deserves attention, but which is very difficult to grasp or express. Perhaps it may be stated thus: Existence has three modes; there is existence in the alam al-mulk, in the alam al-jabarut, and in the alam al-malakut. The first is this world of ours which is apparent to the senses; it exists by the power (qudra) of God, one part proceeding from another in constant change. The alam al-malakut exists by God's eternal decree, without development, remaining in one state without addition or diminution. The alam al-jabarut comes between these two; it seems externally to belong to the first, but in respect of the power of God which is from all eternity (al-qudra al-azaliya) it is included in the second. The soul (nafs) belongs to the alam al-malakut, is taken from it and returns to it. In sleep and in ecstasy, even in this world, it can come into contact with the world from which it is derived. This is what happens in dreams--"sleep is the brother of death," says al-Ghazzali; and thus, too, the saints and the prophets attain divine knowledge. Some angels belong to the world of malakut; some to that of jabarut, apparently those who have shown themselves
