flight, for it was so in effect, of al-Ghazzali was unintelligible to the theologians of the time; since that time it has marked the greatest epoch in the church of Islam after the return of al-Ash'ari.

That it should be unintelligible was natural. No cause could be seen on the surface, except some possible political complications; the cause in reality lay in al-Ghazzali's mind and conscience. He was wandering in the labyrinth of his time. From his youth he had been a sceptical, ambitious student, playing with religious influences yet unaffected by them. But the hollowness of his life was ever present with him and pressing upon him. Like some with us, he sought to be converted and could not bring it to pass. His religious beliefs gradually gave way and fell from him, piece by piece.

At last, the strain became too great and at the court of Nizam al-Mulk he touched for two months the depths of absolute scepticism. He doubted the evidence of the senses; he could see plainly that they often deceived. No eye could perceive the movement of a shadow, but still the shadow moved; a gold piece would cover any star, but a star was a world larger than the earth. He doubted even the primary ideas of the mind. Is ten more than three? Can a thing be and not be? Perhaps; he could not tell. His senses deceived him, why not his mind? May there not be something behind the mind and transcending it, which would show the falsity of its convictions even as the mind showed the falsity of the information given by the senses? May not the dreams of the Sufis be true, and their revelations in ecstasy

the only real guides? When we awake in death, may it not be into a true but different existence? All this —perhaps. And so he wandered for two months. He saw clearly that no reasoning could help him here; he had no ideas on which he could depend, from which he could begin. But the mercy of God is great; He sends His light to whom He wills, a light that flows in, and is given by no reasoning. By it al-Ghazzali was saved; he regained the power to think, and the task which he now set before him was to use this power to guide himself to truth.

When he looked around, he saw that those who gave themselves to the search for truth might be divided into four groups. There were the scholastic theologians, who were much like the theologians of all times and faiths. Second, there were the Ta'limites, who held that to reach truth one must have an infallible living teacher, and that there was such a teacher. Third, there were the followers of philosophy, basing on logical and rational proofs. Fourth, there were the Sufis, who held that they, the chosen of God, could reach knowledge of Him directly in ecstasy. With all these he had, of course, been acquainted to a greater or less degree; but now he settled down to examine them one by one, and find which would lead him to a certainty to which he could hold, whatever might come. He felt that he could not go back to the unconscious faith of his childhood; that nothing could restore. All his mental being must be made over before he could find rest. He began with scholastic theology, but found no help there. Grant the theologians their premises
