Of all books of Jewish philosophy and theology, the Kuzari is distinct for its novelty of approach. The scenario is fictional; the king of the Khazars invites four people - a philosopher, a Christian, a Moslem, and a Jew - to debate the relative merits of their worldviews. With logical arguments that spell out the principles of the Jewish faith and debunk the erroneous beliefs of the others, Rabbi Yehudah Ha Levy's classic work is simultaneously imaginative and rational, creative and informative.
