When the Zohar or Midrash of Simon bar Yochaï was published, it aroused the greatest wonder among the Kabbalists. They seized upon it with avidity. Moses de Leon received vast multitudes of orders to send copies. The question, whence all at once had come so comprehensive a work of an old teacher of the Mishna, not a trace of which had been known till then, was thus answered: Nachmani had exhumed it in Palestine, had sent it to his son in Catalonia, by a whirlwind it had been carried to Aragon or Alicante (Valencia), where it had fallen into the hands of Moses de Leon, who alone possessed the original document. The repute of the newly discovered Kabbalistic treasure soon spread through the whole of Spain. The school of Abulafia at once gave the Zohar the tribute of its acknowledgment, and considered it indisputably genuine. Moses de Leon's wildest hopes were more than realized. There were, of course, Kabbalists who doubted that the Zohar had originated with Simon bar Yochaï and his school, but none the less did they pay homage to the book as to a pure source for Kabbalistic theories. When the Kabbalist Isaac of Accho, who had escaped the massacre that had ensued upon the capture of that city, arrived in Spain, and saw the Zohar, he was staggered, and became desirous of coming to the root of the question, whether this alleged ancient Palestinian work was really genuine, as he had been born and educated in the Holy Land, had associated with Nachmani's pupils, and yet had never heard a syllable about it. When he met Moses de Leon in Valladolid, the latter took a solemn oath that he had in his house at Avila an old copy of the book from the hand of Simon bar Yochaï, and pledged himself to submit it to Isaac of Accho for examination. But Moses de Leon became ill on his journey home, and died in Arevalo (1305). The veil around the origin of the Zohar was wrapped still closer. Two influential men of Avila, David Rafan and Joseph de Avila, had indeed discovered the simple truth from Moses de Leon's wife and daughter. Moses de Leon had never possessed the original copy, but had evolved it out of his own inner consciousness, and had written it with his own hand. His wife frankly related that she had often asked her husband why he published the productions of his own intellect under a strange name, and that he had answered that the Zohar would not, under his own name, have brought him any money, but assigned to Simon bar Yochaï it had been a lucrative source of income.

Thus wife and daughter, without being aware of the full gravity of their assuredly unassailable testimony, unmasked Moses de Leon as a forger. Nevertheless, the Zohar met with the unqualified applause of the Kabbalists, because it supplied a want which would have had to be provided for in one way or another. The Kabbalistic doctrine, which had already gained so much weight, had hitherto been without firm basis; it had no other authority than the very doubtful one of Isaac the Blind. Now the dignified figure of a teacher of the Mishna in communion with departed spirits and celestial hosts and angels confirmed the truths which were not only doubted by many at the time, but absolutely ridiculed. Should they, then, not cling to it and defend it? What Moses de Leon put into the mouth of Simon bar Yochaï, "Many will range themselves round the book Zohar, when it becomes known, and nourish their minds with it at the end of days," actually happened soon after his death. If the Zohar did not bring the Kabbalists anything essentially new, it exhibited to them what they did know in so peculiar a form and language, that they were wonderstruck. Everything in it is contrived for effect, for illusion, and for fascination. The long discussions which Simon bar Yochaï holds with his circle or with the "faithful shepherd," have dramatic power, especially the scene in which, in premonition of his speedy dissolution, he imparts once more what he so often had proclaimed. Full of effect, and, upon minds easily accessible to faith, of transporting and overwhelming influence, are the oft-recurring exclamations in the Zohar: Woe, woe to those who believe, or do not believe, or fail to respect, this and that. Sometimes short prayers are interspersed, which, being elevated and imaginative, are peculiarly fitted to fill the soul with mysterious awe. Even the characteristic terms introduced instead of the usual Kabbalistic forms are calculated to arouse interest by their double sense. The author designated God and the higher spiritual substances (Sefiroth) collectively or in their single parts and effects, as father, mother, the prototype of man, bride, matron, the white head, the large and the small face, the mirror, the higher heaven, the higher earth, lily, apple-orchard, and so on. The pious were gained over to the side of the Zohar, as it attributes to every religious custom and every practice a higher import, a higher sanctity, and a mysterious effect.

So a new text-book of religion was by stealth introduced into Judaism. It placed the Kabbala, which a century before had been unknown, on the same level as the Bible and the Talmud, and to a certain extent on a still higher level. The Zohar undoubtedly produced good, in so far as it opposed enthusiasm to the legal dry-as-dust manner of the study of the Talmud, stimulated the imagination and the feelings, and cultivated a disposition that restrained the reasoning faculty. But the ills which it has brought on Judaism outweigh the good by far. The Zohar confirmed and propagated a gloomy superstition, and strengthened in people's minds the belief in the kingdom of Satan, in evil spirits and ghosts.

Through its constant use of coarse expressions, often verging on the sensual, in contradistinction to the chaste, pure spirit pervading Jewish literature, the Zohar sowed the seeds of unclean desires, and later on produced a sect that laid aside all regard for decency. Finally, the Zohar blunted the sense for the simple and the true, and created a visionary world, in which the souls of those who zealously occupied themselves with it were lulled into a sort of half-sleep, and lost the faculty of distinguishing between right and wrong. Its quibbling interpretations of Holy Writ, adopted by the Kabbalists and others infected with this mannerism, perverted the verses and words of the Holy Book, and made the Bible the wrestling-ground of the most curious, insane notions. The Zohar even contains utterances which seem favorable to the Christian dogma of the Trinity of the Godhead. The mystics dismembered the fair form of Holy Writ, indulged in mad sport, and stupefied all sense for truth, but they were scarcely more guilty in this respect than the so-called philosophers of the time. Maimuni's attempt to bring Judaism and its religious literature into consonance with reason, to give certain too realistic verses of the Bible a philosophical, or at least a tolerable sense, and place religious precepts on the basis of an intelligible, acceptable purpose, encouraged half-learned men to explain everything and anything in the same way. Hence the allegorizing of the Scriptures, the Agada, and the rites, was carried to an incredible extreme. These pseudo-philosophers divested the stories of the creation and of the patriarchs of their historical character, and interpreted them as philosophical commonplaces, in which they sported with Aristotelian and Maimunist terms, as the Zohar with Kabbalistic terms. Abraham and Sarah, for example, denote to the allegorists matter and form, Pharaoh denotes vicious desires, Egypt the body, the land of Goshen the heart, Moses the divine spirit, and the Urim and Thummim, which the High Priest wore on his breast in the Temple, were the astrolabe of the astronomers, with which they calculated time, longitude and latitude. If there had been at that time any Jewish thinkers of the first rank, they would have made serious efforts to put a stop to this childish proceeding, whether Kabbalistic or pseudo-philosophical. But the age of Ben Adret happened to be poor in great intellects. Even the two chief representatives of the philosophy of that time, Shem-Tob Falaquera and Isaac Albalag, were not above mediocrity, and were themselves tainted with the current errors.

There were, however, certain men of bolder spirit, who from philosophical premises drew conclusions endangering the stability of Judaism. Like their predecessors, the Alexandrine allegorists, many intelligent and consistent thinkers were induced at this time to disregard the ceremonies of Judaism by assigning erroneous purposes to religious precepts. As the ceremonies are intended simply to awaken certain religious, philosophical, or moral feelings, they argued, it is sufficient to call up these thoughts, to be penetrated by them, to occupy one's mind constantly with them, while the observance of religious customs is superfluous. Several members of this school denied Moses' prophetic character, accepting him only as an ordinary lawgiver, such as other nations had, and thus rejected the divinity of the Torah. The pseudo-philosophers cast a doubt upon the very fundamentals of Judaism, and thereby provoked a reaction injurious to free inquiry.

The chief authority of this allegorical school was a man of vast erudition, but full of crotchets, who, without desiring it, occasioned violent conflicts. This was Levi ben Abraham ben Chayim, of Villefranche, not far from Perpignan (born about 1240, died after 1315). Coming from a respectable family of scholars, he was deeply read in the Talmud; but he was more attracted by Maimuni's philosophy and Ibn-Ezra's astrology, being a warm adherent of the belief of the latter in the influence of the stars over human destiny. Of a volatile rather than a solid mind, Levi ben Chayim had no perfect conception of Maimuni's aims. To him Judaism resolved itself into philosophical platitudes, which, preposterous and childish as they sound to us, were, strange to say, regarded by the people of early times as profound wisdom. Ben Chayim was the disseminator of that superficial method satisfied with formulæ instead of thoughts. He composed two chief works, one in verse, the other in prose, a kind of encyclopædia, in which he applied the theory derived from Maimuni to all branches of knowledge. In these books he translated the historical narratives in the Bible into philosophical generalities, explained the standing still of the sun on the occasion of Joshua's victory as a natural occurrence, and in general, adopted any method of expounding which depends on word-twisting. Levi ben Chayim repudiated the allegorical interpretations of laws; in fact, he denounced the allegorists as heretics, and desired to preserve the historical character of the biblical narratives as much as possible. Like his prototype, Ibn-Ezra, he tried to keep secret his deepest convictions, so that not even his friends could fathom his ideas. This Judaism, disfigured by absurd philosophical interpretations, was not only privately taught, but preached in the synagogues.

The home of this pseudo-philosophy was the not insignificant congregation of Perpignan, the capital of the province of Roussillon, which belonged to the kingdom of Aragon. Although the Jews had no enviable lot, and were compelled to live in the most miserable part of the town, that assigned to lepers, they nevertheless preserved a taste for science and free inquiry, and eagerly awaited the new theories taught by the exponents and followers of Maimuni's philosophy. Here poor Levi of Villefranche had found a place of refuge at the house of a rich and influential man, Don Samuel Sulami or Sen Escalita, whose piety, learning and liberality were praised beyond measure by his contemporaries. "From Perpignan to Marseilles there is not another who can be compared with Samuel Sulami in knowledge of the Law, benevolence, piety and humility. He gives charity in secret, his house is open to every traveler; and he is indefatigable in getting books for his collection." He corresponded on learned topics with Ben Adret, and took interest in the philosophical interpretation of the Bible and the Agada. Even the rabbi of Perpignan was a friend of free thought and a determined enemy of mummified orthodoxy and the unreflecting faith of the literalist. This was Don Vidal Menachem ben Solomon Meïri (born Elul, 1249, died about 1306), little celebrated in his own time, but none the less of great importance. Though not of commanding influence, he possessed an attractive personality. He had what nearly all his contemporaries sorely lacked, moderation and tact. These qualities are revealed particularly in Meïri's style. Nearly all the Jewish authors of Spain and Provence wrote their prose and verse in a redundant, bombastic style, as if the whole literary thesaurus of the Bible were needed to express a meager idea. The much-admired model of this time, the moral poet Yedaya Bedaresi, is so prolix in saying the most ordinary platitude, that one has to peruse whole pages of his apology, reflections, and miscellaneous writings before coming across a tolerable idea. The style in vogue, a mosaic of Biblical phrases, favored verbosity. But Don Vidal Meïri forms a glorious exception to this practice, his style being terse and clear. In his commentaries to the tractates of the Talmud which relate to ceremonial duties, he proceeds throughout in a methodical manner, advances from the general to the particular, arranges his material in lucid order, and seeks to give the reader information, not to confuse him. Of a similar character is Meïri's exposition of Holy Writ. The philosophers and mystics always endeavored to find some higher meaning in it, the simple explanation being too prosaic for them, and accordingly they put upon the Bible their own extravagant nonsense. Not so Meïri. He certainly assumed that there are many commands and narratives in the Bible which point to something higher than the literal meaning, but the majority of them must, he maintained, be taken quite literally. Meïri was naturally dissatisfied with the extravagant mannerisms of the allegorists, but it did not enter his mind to reject the good together with the bad, to interdict learning because of its abuse.

These proceedings were not regarded quite so calmly by certain bigots, dwelling in the city which had produced the obscurantist Solomon of Montpellier, the proscriber of Maimuni and his compositions, and author of so much dissension and evil. Although pseudo-philosophical extravaganzas were not more dangerous than the follies of the Kabbalists, the watchers of Zion nevertheless overlooked the latter, and waged energetic warfare with the former, so that the philosophers obtained more weight than they would otherwise have had. The bigots of Montpellier well-nigh kindled the fire of discord in Jacob. The first instigator of this ill-timed zeal belonged to that class of men who mark off the province of faith according to an exact rule, denounce every movement and opinion which transgress their limit as heresy, and desire to have them rooted out with anathemas and scourges, where possible with fire and sword—a class of men in whom fanatical zeal cannot be separated from a kind of egoism. To this category belonged Abba-Mari ben Moses, of Montpellier, or, as his aristocratic title ran, Don Astruc En-Duran de Lünel. Of a respectable family, and of great influence in the capital of Languedoc, Abba-Mari was certainly not without culture, and he had great veneration for Maimuni and his compositions; but he had irrevocably attached himself to the Jewish creed as laid down by Nachmani, and was indignant if any one ventured to consider it from the point of view of another system. He did not object to miraculous tales; on the contrary, the more the better. The conclusions of philosophy and science, which denied the possibility of these miracles, in no way disturbed him. In the choice between Moses and Aristotle, or between the authorities of the Talmud and the upholders of philosophy, he was not for a moment doubtful to whom to give the preference. To be sure, this narrow-minded point of view is justifiable; but Abba-Mari wanted to thrust his opinion upon every one else, and to persecute all who thought otherwise. Not only did he hold in abomination the allegorical exegesis publicly preached, but he reprobated the study of all profane literature as the cause of this aberration. He regretted that the scourge could no more be brought into requisition to silence those who filled their minds with such learning as endangered religion.

Abba-Mari, however, did not possess sufficient authority to proceed against Levi of Villefranche and his school. He addressed himself to the most influential rabbi of the time, Ben Adret of Barcelona, and charged that their perversities would accomplish the dissolution of Judaism, if a restraint were not put upon them. He importuned Ben Adret to exercise his great influence. The rabbi naturally found the circumstance deplorable that "strangers had forced their way through the gates of Zion." He exhorted Abba-Mari to organize a party to oppose this extravagant movement, but positively refused his support, as he did not like to interfere in the affairs of congregations abroad. Other bigots, however, took up the cause, and hurried it to a crisis, among them Don Bonafoux Vidal, of Barcelona, and his brother, Don Crescas Vidal, who had moved to Perpignan, both highly respected and learned, but as intolerant as Abba-Mari. Don Crescas made a proposition, which met with much applause. The study of science, and the reading of profane literature in general, was to be prohibited to Jewish youths till their thirtieth year. Only men of mature age, "who had filled their minds with the Bible and the Talmud, were to be allowed to warm themselves by the strange fires of philosophy and the natural sciences." Although Ben Adret did not feel disposed to take measures against the study of science, he nevertheless considered it his duty to persecute the provoker of so much animosity. He took umbrage at the pious Samuel Sulami for granting a heretic shelter in his house, thus giving him an opportunity to spread his pernicious views. He harassed Samuel Sulami so unmercifully, and subjected his conscience to such torment, that the man, not very remarkable for strength of character, became shaken in his previous convictions. When a daughter of his died he believed that it was a punishment for his sinfulness, and renounced his hospitality to Levi. Many members of the congregation of Perpignan bitterly resented the suspicion of heresy cast upon Levi, and as they knew Ben Adret to be a man of stainless character, they vented their dissatisfaction on the instigator, Abba-Mari, to whom they imputed sordid ulterior designs and personal motives.

Abba-Mari and his allies, who felt themselves helpless without powerful support, labored without intermission to inflame the zeal of the Barcelona rabbinate, that it might forbid free inquiry and the study of science. At the same time they promised the co-operation of the whole congregation of Montpellier, which, being the chief one in southern France, would draw other communities after it. Ben Adret and his college, imagining from Abba-Mari's exaggerated description that Judaism was in the greatest danger, were at last determined to take up the matter, but desired first to sound the congregation of Montpellier as to its feeling on the subject, and for this purpose sent a letter to be read before the members in case they felt disposed to join them in interdicting the study of the natural sciences. But as soon as the proposed ban against the sciences became known, decided opposition arose among the most important men of the congregation.
