Similar in character, but fundamentally opposed to him in the disposition of his mind, was his friend and senior, Isaac ben Sheshet Barfat (Ribash, born 1310, died about 1409). A native of Barcelona, and having studied under Ben Adret's son and pupils, Isaac ben Sheshet may, in a measure, be considered a disciple of Ben Adret. He acquired his teacher's capacity for seizing the spirit of the Talmud and expounding it lucidly, and far surpassed him in hostility to secular studies. Ben Adret had permitted the circumstances of his times to extort from him the prohibition of such studies, as far as raw youths were concerned; Ben Sheshet, in his rigid orthodoxy, took the view that even mature men should hold aloof from them, although at that period there was but little fear of heresy. The physical sciences and philosophy, he held, should be completely avoided, as they were calculated to undermine the two essential supports of the Torah, the doctrines of the creation, and of a Providence; because they exalted reason over faith, and generated doubts of miracles. In Gersonides, and even Maimuni, Ben Sheshet found illustrations of the pernicious effects of philosophic speculation. He granted that they were men of incomparable genius, but he insisted that they had been seduced by philosophy to adopt heterodox views, and explain certain miracles of the Bible rationalistically. Ben Sheshet was of high moral character; his disposition was kindly, and on several occasions he willingly sacrificed his personal interests to advance the common good and to promote peace. But when he suspected the violation of a Talmudical precept or the non-observance of even an unessential custom, his mildness was immediately transformed into most obdurate severity. On account of his Talmudical learning, his clear, penetrating intellect, and his irreproachable character, he was much sought after. The important community of Saragossa elected him its rabbi. Immediately on taking office, Isaac ben Sheshet gave an illustration of the tenacity with which he clung to the letter of the Law, even when it conflicted with the spirit. He observed, with regret, that the practice obtained of reading the book of Esther on the feast of Purim in a Spanish translation, for the benefit of the women. This practice had been introduced into other Spanish communities, and was not only applauded by all men of common sense, but had even been authorized by a few rabbis, who considered it unobjectionable from a Talmudical point of view. Ben Sheshet raised a cry of alarm, as if Judaism had been threatened with ruin. He called to his assistance the authority of his teacher, Nissim Gerundi, and together they opposed the excellent custom with sophistical argument. They appear to have been successful in abolishing it.
