The one was about the year 1232, on the occasion of the great struggle about Maimonides’ _Guide of the Perplexed_, and the first book of his great Compendium of the Law. The Maimonists looked upon these works almost as a new revelation, whilst the Anti‐Maimonists condemned both as heretical, or at least conducive to heresy.(71) It would be profitless to reproduce the details of this sad affair. The motives may have been pure and good, but the actions were decidedly bad. People denounced each other, excommunicated each other, and did not (from either side) spare even the dead from the most bitter calumnies. Nachmanides stood between two fires. The French Rabbis, from whom most of the Anti‐Maimonists were recruited, he held in very high esteem and considered himself as their pupil. Some of the leaders of this party were also his relatives. He, too, had, as we shall see later on, a theory of his own about God and the world little in agreement with that of Maimonides. It is worth noting that Nachmanides objected to calling Maimonides “our teacher Moses” (Rabbenu Mosheh),(72) thinking it improper to confer upon him the title by which the Rabbis honoured the Master of the Prophets. The very fact, however, that he had some theory of the Universe shows that he had a problem to solve, whilst the real French Rabbis were hardly troubled by difficulties of a metaphysical character. Indeed, Nachmanides pays them the rather doubtful compliment that Maimonides’ work was not intended for them, who were barricaded by their faith and happy in their belief, wanting no protection against the works of Aristotle and Galen, by whose philosophy others might be led astray. In other words, their strength lay in an ignorance of Greek philosophy, to which the cultivated Jews of Spain would not aspire. Nachmanides was also a great admirer of Maimonides, whose virtues and great merits in the service of Judaism he describes in his letter to the French Rabbis. Thus, the only way left open to him was to play the part of the conciliator. The course of this struggle is fully described in every Jewish history. It is sufficient to say that, in spite of his great authority, Nachmanides was not successful in his effort to moderate the violence of either party, and that the controversy was at last settled through the harsh interference of outsiders who well‐nigh crushed Maimonists and Anti‐Maimonists alike.
