 With respect to many, if not most issues, there exist significant differences of opinion among individuals who seem to be equally knowledgeable and sincere. Individuals who apparently have access to the same information and are equally interested in the truth do in fact affirm incompatible perspectives on, for instance, significant social, political, and economic issues. Such diversity of opinion, though, is nowhere more evident than in the area of religious thought. On almost every religious issue there are honest, knowledgeable people who hold significantly diverse, often incompatible beliefs.
