Elijah avoided the method of pilpul, which was meant to exercise the mind by inventing artificial contradictions in the Talmudic text and subsequently removing them. Knowing by heart almost the entire Talmudic and rabbinic literature, he had no difficulty in solving the most complicated questions of Jewish law, and, guided by subtle critical observations, occasionally allowed himself to emend the text of the Talmud. Elijah Gaon wrote commentaries and all sorts of "annotations" to Biblical, Talmudic, and Cabalistic books, but his style was, as a rule, careless, consisting of hints, references, and abbreviations, intelligible only to the learned reader. In his spare moments he occasionally wrote about Hebrew grammar and mathematical sciences. Rabbinical learning was his native element, embodying for him the whole meaning of religion. In questions of religious ceremonialism he was a rigorist, adding here and there new restrictions to the multifarious injunctions of the _Shulhan Arukh_. He was the idol of all the learned rabbis of Lithuania and other countries, but the masses understood him as little as he understood them. A spiritual aristocrat, he was bound to condemn severely the "plebeian" doctrine of Hasidism. The latter offended in him equally the learned Talmudist, the rigorous ascete, and the strict guardian of ceremonial Judaism, of which certain minutiae had been modified by the Hasidim after their own fashion. As far back as 1772, when the first Hasidic societies were secretly organized in Lithuania, and several of their leaders were discovered in Vilna, the rabbinical Kahal court of that city pronounced, with the permission of Elijah Gaon, the herem against the sectarians. From Vilna circulars were sent out to the rabbis of other communities, calling upon them to wage war against the "godless sect." In many towns of Lithuania the Hasidim became the object of persecution. The rabbis of Galicia, having been forewarned from Vilna, followed suit, and at a meeting held in Brody, during the local fair, issued a most rigorous herem against every Jew following the Hasidic liturgy, dressing in white on Saturdays and holidays,[205] and in general participating in the conventicles of the Hasidim.
