"The friends of reason," said Samuel ben Meir, "should steep themselves in this principle of our sages, that natural exegesis can never be superseded. It is true that the chief aim of the Torah was to outline for us rules of religious conduct, which we discover behind the literal meaning through Haggadic and Halakic interpretation. And the ancients, moved by their piety, occupied themselves only with Midrashic exegesis as being the most important, and they failed to dwell at great length upon the literal meaning. Add to this the fact that the scholars advise us not to philosophize too much upon the Scriptures. And R. Solomon, my maternal grandfather, the Torch of the Captivity, who commented on the Law, the Prophets, and the Hagiographa, devoted himself to the development of the natural meaning of the text; and I, Samuel son of Meir, discussed his explanations with him and before him, and he confessed to me that if he had had the leisure, he would have deemed it necessary to do his work all over again by availing himself of the explanations that suggest themselves day after day."[90] It seems, therefore, that Rashi only gradually, as the result of experience and discussion, attained to a full consciousness of the requirements of a sound exegesis and the duties of a Biblical commentator. What the grandfather had not been able to do was accomplished by the grandson. The commentary of Samuel ben Meir realized Rashi's resolutions. Though Rashi may not have been irreproachable as a commentator, he at least pointed out the way, and his successors, enlightened by his example, could elaborate his method and surpass it, but only with the means with which he provided them. We must take into account that he was almost an originator, and we readily overlook many faults and flaws in remembering that he was the first to prepare the material. * * * * * Grammar and lexicography are the two bases of exegesis. Rashi was as clever a grammarian as was possible in his time and in his country. At all events he was not of the same opinion as the Pope, who rebuked the Archbishop of Vienna for having taught grammar in his schools, because, he said, it seemed to him rules of grammar were not worthy the Sacred Text, and it was unfitting to subject the language of Holy Scriptures to these rules. Rashi in his explanations pays regard to the laws of language, and in both his Talmudic and Biblical commentaries, he frequently formulates scientific laws, or, it might be said, empiric rules, regarding, for instance, distinctions in the usage of words indicated by the position of the accent, different meanings of the same particle, certain vowel changes, and so on. Thus, we have been able to construct a grammar of Rashi, somewhat rudimentary, but very advanced for the time.
