This treatise, finished in the year 934, was the first systematic attempt to bring revealed religion into harmony with Greek philosophy. Saadiah was thus the forerunner, not only of Maimonides, but also of the Christian school-men. No Jew, said Saadiah, should discard the Bible, and form his opinions solely by his own reasoning. But he might safely endeavor to prove, independently of revelation, the truths which revelation had given. Faith, said Saadiah again, is the sours absorption of the essence of a truth, which thus becomes part of itself, and will be the motive of conduct whenever the occasion arises. Thus Saadiah identified reason with faith. He ridiculed the fear that philosophy leads to scepticism. You might as well, he argued, identify astronomy with superstition, because some deluded people believe that an eclipse of the moon is caused by a dragon's making a meal of it. For the last few years of his life Saadiah was reinstated in the Gaonate at Sura. The school enjoyed a new lease of fame under the brilliant direction of the author of the great work just described. After his death the inevitable decay made itself felt. Under the Moorish caliphs, Spain had become a centre of Arabic science, art, and poetry. In the tenth century, Cordova attained fame similar to that which Athens and Alexandria had once reached. In Moorish Spain, there was room both for earnest piety and the sensuous delights of music and art; and the keen exercise of the intellect in science or philosophy did not debar the possession of practical statesmanship and skill in affairs. In the service of the caliphs were politicians who were also doctors, poets, philosophers, men of science. Possession of culture was, indeed, a sure credential for employment by the state. It was to Moorish Spain that the centre of Judaism shifted after the death of Saadiah. It was in Spain that the finest fruit of Jewish literature in the post-Biblical period grew. Here the Jewish genius expanded beneath the sunshine of Moorish culture. To Moses, the son of Chanoch, an envoy from Babylonia, belongs the honor of founding a new school in Cordova. In this he had the support of the scholar-statesman Chasdai, the first of a long line of medieval Jews who earned double fame, as servants of their country and as servants of their own religion. To Chasdai we must now turn. BIBLIOGRAPHY SAADIAH. Graetz.--III, 7. Schiller-Szinessy.--_Encycl. Brit._, Vol. XXI, p. 120. M. Friedländer.--_Life and Works of Saadia_. _J.Q.R._, Vol. V, p. 177.
