Guide for the Perplexed, Part 1, The by Moses Maimonides (1138 - 1204)

The Guide for the Perplexed by Mūsá ibn Maymūn (known throughout the Christian West as Moses Maimonides) is regarded as one of the most important works of Medieval Jewish thought. The book attempted to harmonize the philosophy of Aristotle with the Rabbinical teachings, but was regarded by many at the time as antithetical to Jewish theology, despite its earnest arguments in vindication of the ways of God. - Summary by Daniel Davison
