<P> Over the next four centuries, the Mishnah underwent discussion and debate in both of the world's major Jewish communities (in Israel and Babylonia). The commentaries from each of these communities were eventually compiled into the two Talmuds, the Jerusalem Talmud (Talmud Yerushalmi) and the Babylonian Talmud (Talmud Bavli). These have been further expounded by commentaries of various Torah scholars during the ages . </P> <P> In the text of the Torah, many words are left undefined and many procedures are mentioned without explanation or instructions . Such phenomena are sometimes offered to validate the viewpoint that the Written Law has always been transmitted with a parallel oral tradition, illustrating the assumption that the reader is already familiar with the details from other, i.e., oral, sources . </P> <P> Halakha, the rabbinic Jewish way of life, then, is based on a combined reading of the Torah, and the oral tradition--the Mishnah, the halakhic Midrash, the Talmud and its commentaries . The Halakha has developed slowly, through a precedent - based system . The literature of questions to rabbis, and their considered answers, is referred to as responsa (in Hebrew, Sheelot U-Teshuvot .) Over time, as practices develop, codes of Jewish law are written that are based on the responsa; the most important code, the Shulchan Aruch, largely determines Orthodox religious practice today . </P> <P> Jewish philosophy refers to the conjunction between serious study of philosophy and Jewish theology . Major Jewish philosophers include Solomon ibn Gabirol, Saadia Gaon, Judah Halevi, Maimonides, and Gersonides . Major changes occurred in response to the Enlightenment (late 18th to early 19th century) leading to the post-Enlightenment Jewish philosophers . Modern Jewish philosophy consists of both Orthodox and non-Orthodox oriented philosophy . Notable among Orthodox Jewish philosophers are Eliyahu Eliezer Dessler, Joseph B. Soloveitchik, and Yitzchok Hutner . Well - known non-Orthodox Jewish philosophers include Martin Buber, Franz Rosenzweig, Mordecai Kaplan, Abraham Joshua Heschel, Will Herberg, and Emmanuel Lévinas . </P>
