We find the same struggle between philosophical system and national sentiment in Maimonides’ attitude to the Hebrew language. From the point of view of his system he naturally saw no difference between one language and another: what matters is the idea, not its external dress. Hence he lays it down that speech “is not to be forbidden or allowed, loved or despised, according to the language, but according to the subject. That which is lofty may be said in whatever language; that which is mean may not be said in any language.”[165] Practising what he preached, he wrote most of his books not in Hebrew, but in Arabic, because he thought that by being written in the ordinary language of his age and his surroundings they would be of greater use from the point of view of their subject-matter. The only book that he wrote in Hebrew was the _Mishneh Torah_; and here also he was guided by practical considerations. He chose the language of the Mishnah because he wanted his people to regard the book with respect as a kind of second Mishnah. The beautiful Mishnaic language would carry off the “true opinions,” which needed the help of a sacred language to make them holy and bring them under the ægis of religion. Thus far Maimonides the philosopher. But in his letters we find clear indications that after he had finished his work his national sentiment proved stronger than his philosophy, and he regretted that he had not written his other works in Hebrew as well. Not only that, but he actually thought of translating them into the national language himself, so as “to separate that which is precious from that which is defiled, and to restore stolen goods to their rightful owner.” But the decline of his powers in old age did not permit him to carry out this intention, and the Hebrew translation had to wait for other hands. Some of it was done in his lifetime; and his letter to the translator of the _Guide_ shows how pleased he was.[166]
