Whilst thus giving the general principles of Judaism, he had so far not justified it in all its details. In order to do this, Jehuda Halevi propounded a view which is certainly original and ingenious. The truth of the creation, as related in the Torah, being pre-supposed, he starts from the fact that Adam was in soul and body completely perfect when he came from the hand of the Creator, without any disturbing ancestral influences, and the ideal, after which man should strive, was set forth in all its purity. All truths which are accessible to the human soul might have been known to Adam without any wearisome study, by his innate consciousness, and he possessed, so to speak, a prophetic nature, and was therefore called the son of God. This perfection, this spiritual and moral endowment, he bequeathed to those of his descendants who, by virtue of their spiritual fitness, were capable of receiving it. Through a long chain of ancestors, with some slight interruptions, this innate virtue passed to Abraham, the founder of the family of the Israelites, and thence to the ancestors of the twelve tribes. The people of Israel thus forms the heart and kernel of the human race, and through divine grace, and especially through the gift of prophecy, it was peculiarly fitted for this position. This ideal nature elevates the possessor; it may be said to constitute the intermediate step between man and the angels. In order to attain and preserve this divine gift, it is necessary to have some place which, by reason of the circumstances of the climate, is of help in promoting a higher spiritual life. For this purpose God selected the land of Canaan. Like Israel, so the Holy Land was specially chosen; it was selected because it lies at the center of the earth. There the rule of God was made manifest by the rise of prophets and by extraordinary blessings and curses, which were supernatural. The precepts and prohibitions which Judaism ordains are means whereby the divinely prophetic nature in the Israelite nation may be nurtured and preserved. To this end the priests of the house of Aaron were appointed, the Temple erected, the sacrificial laws and the whole code established. God alone, from whom all these laws emanated, knows in how far they aid in furthering this great aim. Human wisdom durst not find fault with or change them, because the most unimportant alteration might easily cause the grand end to be lost sight of, even as nature brings forth varied productions by slight changes of the soil and climate. The duties of morality, or the laws of reason, do not constitute the peculiarity of Judaism, as many imagine. These are rather the bases on which the commonwealth was established, as even a robber band cannot dispense with justice and fairness if it wishes to hold together. The religious duties are the true essentials of Judaism, and are intended to preserve in the people of Israel divine light and grace and permanent prophetic inspiration.
