their teacher's hints by themselves, in which case the teacher was allowed to teach them indirectly. In practice, however, the mass of detailed rabbinic writings on this subject often crosses the line from hint to detailed teachings. After justifying this "crossing of the line" from hints to direct instruction, Maimonides explains the basic mystical concepts via the Biblical terms referring to Spheres, elements and Intelligences. In these chapters, however, there is still very little in terms of direct explanation. This is followed by an analysis of the moral aspects of the universe. Maimonides deals with the problem of evil (for which people are considered to be responsible because of free will), trials and tests (especially those of Job and the story of the Binding of Isaac) as well as other aspects traditionally attached to God in theology, such as providence and omniscience: "Maimonides endeavors to show that evil has no positive existence, but is a privation of a certain capacity and does not proceed from God; when, therefore, evils are mentioned in Scripture as sent by God, the Scriptural expressions must be explained allegorically. Indeed, says Maimonides, all existing evils, with the exception of some which have their origin in the laws of production and destruction and which are rather an expression of God's mercy, since by them the species are perpetuated, are created by men themselves." Maimonides then explains his views on the reasons for the 613 mitzvot, the 613 laws contained within the five books of Moses. Maimonides divides these laws into 14 sections—the same as in his Mishneh Torah. However, he departs from traditional Rabbinic explanations in favour of a more physical/pragmatic approach by explaining the purpose of the commandments (especially of sacrifices) as intending to help wean the Israelites away from idolatry. Having culminated with the commandments, Maimonides concludes the work with the notion of the perfect and harmonious life, founded on the correct worship of God. The possession of a correct philosophy underlying Judaism (as outlined in the Guide) is seen as being an essential aspect in true wisdom. Reception While many Jewish communities revered Maimonides' work and viewed it as a triumph, others deemed many of its ideas heretical. The Guide was often banned, and in some occasions, even burned. In particular, the adversaries of Maimonides' Mishneh Torah declared war against the "Guide". His views concerning angels, prophecy, and miracles—and especially his assertion that
