There can be no doubt that the Kabbalah contains the ripest fruit of spiritual and mystical speculation which the Jewish world produced on subjects which had hitherto been obscured by the gross anthropomorphism of such men as Maimonides and his school. We can understand the revolt of the devout Hebrew mind from traditions like those which represented Jehovah as wearing a phylactery, and as descending to earth for the purpose of taking a razor and shaving the head and beard of Sennacherib. The theory of the _Sephiroth_ was at least a noble and truly reverent guess at the mode of God’s immanence in nature. This conception won the favor of Christian philosophers in the Middle Ages, and, indeed, was adopted or adapted by the angelic Doctor Aquinas himself, the foremost of ecclesiastical and scholastic metaphysicians. The psychology of the Kabbalah, even its treatment of the soul’s preëxistence before union with the body, found many advocates among Gentile and even Christian philosophers. We are therefore led to the conclusion that the Kabbalah is by far the most exalted, the most profound and the most interesting of all that mass of traditional literature which comprises, among other writings, such remains as the Targums and the Talmud. A study of Hebrew literature would indeed be incomplete unless it included the Talmud. “Talmud” in Hebrew means “Doctrine,” and this strange work must be looked upon as a practical handbook, intended for the Jews who, after the downfall of Jerusalem and the Dispersion, found that most of the Law had to be adjusted to new circumstances, in which the institution of sacrifices and propitiatory offerings had been practically abolished. The Talmud contains the decisions of Jewish doctors of many generations on almost every single question which might puzzle the conscience of a punctilious Jew in keeping the Law under the altered conditions of the nation. The basis of the Talmud is the Mishna, _i.e._, an explanation of the text of the Mosaic laws, and their application to new cases and circumstances. The Mishna has been well described by the illustrious Spanish Jew, Maimonides, who in the twelfth century published it at Cordova, with a preface, in which he says: “From Moses, our teacher, to our holy rabbi, no one has united in a single body of doctrine what was publicly taught as the oral law; but in every generation, the chief of the tribunal, or the prophet of his day, made memoranda of what he had heard from his predecessors and instructors, and communicated it orally to the people. In like manner each individual committed to writing, for his own use and according to the degree of his ability, the oral laws and the information he had received respecting the interpretation of the Bible, with the various decisions that had been pronounced in every age and sanctified by the authority of the great tribunal. Such was the form of proceeding until the coming of our Rabbi the Holy, who first collected all
