Religious views on truth
There is no unilateral agreement among the different denominations of Judaism concerning truth. In Orthodox Judaism, truth is the revealed word of God, as found in the Hebrew Bible, and to a lesser extent, in the words of the sages of the Talmud. For Hasidic Jews truth is also found in the pronouncements of their rebbe, or spiritual leader, who is believed to possess divine inspiration. Kotzk, a Polish Hasidic sect, was known for their obsession with truth.
Orthodox Judaism
Orthodox Judaism may be categorized according to varying criteria. The most recognizable sub-group are the "Haredim" (literally, "anxious" or "fervent"), also known as Ultra-Orthodox, strictly Orthodox and the like. They form the conservative, strict and self-segregating part of the Orthodox spectrum. "Haredim" are characterized by a minimal engagement with modern society and culture if not their wholesale rejection, by avowed precedence given to religious values, and by a high degree of rabbinic authority and involvement in daily life. In spite of many differences, "Haredi" rabbis and communities generally recognize each other as such, and therefore accord respect and legitimacy between them. They also hold a lukewarm or negative assessment of more modernist Orthodox groups. "Haredim" are easily discerned by their mode of dress, often all black for men and modest by religious standards for women (including hair covering, long skirts, etc.)
