This state of affairs produced in Maimonides, while he was still young, an ardent desire to stand in the breach and make Judaism fit to fulfil the double function—theoretical and practical—which it had as the only “divine religion.” For this purpose it was necessary on the one hand to show the whole people, in a form suited to its comprehension, the “true opinions” contained in the _Torah_, and on the other hand to rescue the practical commandments from the ocean of Talmudic disputation and to teach them in a short and simple manner, so that they should be easily remembered and become familiar to the people. But in those early days Maimonides had not the courage to strike out a new line and to present the whole content of religion in an entirely fresh manner in conformity with his philosophical system. Hence he chose a line which was already familiar, and decided to supply the need of his own age by the help of a book which in its time had been intended to fulfil a somewhat similar purpose—the Mishnah. Thus it was in the form of a Commentary on the Mishnah that he tried to give his contemporaries what they lacked: to wit, clear doctrine and a plain rule of practice. Wherever the Mishnah leaves a point in doubt, he gives the decision laid down in the Talmud; and wherever the Mishnah hints at some theoretical opinion, he takes advantage of the opportunity to explain the “true opinions.”[142] This latter process was, of course, especially important to him; and he sometimes expatiates on the subject at much greater length than is usual in a Commentary of the ordinary kind.[143] Thus he was able to introduce into his Commentary, besides a mass of scattered notes, complete essays on questions of faith and philosophy in the form of Introductions to different sections of the Mishnah.[144] Maimonides gave a great deal of work to this Commentary, which he began and finished in his years of trouble and wandering. In the result he produced a masterpiece, which remains to this day superior to all later Commentaries on the Mishnah. But he did not achieve the principal object for which he took so much trouble: he did not make religion effective. His Commentary did not become widely known, and made no great impression; still less did it bring about a revolution in popular opinion, as its author hoped that it would. And it failed of its object on the practical as well as on the theoretical side. Many of the later laws, which have no basis in the Mishnah, could not be included in it; and those that were included were scattered about in no proper order, because the Mishnah itself has no strict order. But as Maimonides grew older and reached middle life, years brought him wider knowledge and greater confidence in himself. This self-confidence gave him courage and decided him to approach his goal by another road. He would produce a work of striking originality, such as no Jew had ever produced before.
