Weiss. (See Jay Harris Guiding the Perplexed in the Modern Age Ch. 5) Eventually, their work came to be one of the formative parts of Conservative Judaism. Another aspect of this movement is reflected in Graetz's History of the Jews. Graetz attempts to deduce the personality of the Pharisees based on the laws or aggadot that they cite, and show that their personalities influenced the laws they expounded. The leader of Orthodox Jewry in Germany Samson Raphael Hirsch, while not rejecting the methods of scholarship in principle, hotly contested the findings of the Historical-Critical method. In a series of articles in his magazine Jeschurun (reprinted in Collected Writings Vol. 5) Hirsch reiterated the traditional view and pointed out what he saw as numerous errors in the works of Graetz, Frankel and Geiger. On the other hand, many of the 19th century's strongest critics of Reform, including strictly orthodox rabbis such as Zvi Hirsch Chajes, used this new scientific method. The Orthodox rabbinical seminary of Azriel Hildesheimer was founded on the idea of creating a "harmony between Judaism and science". Other Orthodox pioneers of scientific Talmud study were David Zvi Hoffmann and Joseph Hirsch Dünner. The Iraqi rabbi Yaakov Chaim Sofer notes that the text of the Gemara has had changes and additions, and contains statements not of the same origin as the original. See his Yehi Yosef (Jerusalem, 1991) p. 132 "This passage does not bear the signature of the editor of the Talmud!" Orthodox scholar Daniel Sperber writes in "Legitimacy, of Necessity, of Scientific Disciplines" that many Orthodox sources have engaged in the historical (also called "scientific") study of the Talmud. As such, the divide today between Orthodoxy and Reform is not about whether the Talmud may be subjected to historical study, but rather about the theological and halakhic implications of such study. Contemporary scholarship Some trends within contemporary Talmud scholarship are listed below. Orthodox Judaism maintains that the oral Torah was revealed, in some form, together with the written Torah. As such, some adherents, most notably Samson Raphael Hirsch and his followers, resisted any effort to apply historical methods that imputed specific motives to the authors of the Talmud. Other major figures in Orthodoxy, however, took issue with Hirsch on this matter, most prominently David Tzvi Hoffmann. Some scholars hold that there has been extensive editorial reshaping of the stories and statements within the Talmud. Lacking outside confirming
