I will be concerned with only one problem about truth which is raised by the diversity of religions which exist in the world. The problem is this: many religions claim to state truths about the nature of the universe and human destiny which are important or even necessary for human salvation and ultimate well-being. Many of these truths seem to he incompatible; yet there is no agreed method for deciding which are to he accepted; and equally intelligent, informed, virtuous and holy people belong to different faiths. It seems, therefore, that a believing member of any one tradition is compelled to regard all other traditions as holding false beliefs and therefore as not leading to salvation. Since each faith forms a minority of the world's population, all religious believers thus seem committed to saying that most intelligent, virtuous and spiritually devoted people cannot know the truth or attain salvation. This is a problem, because it is in tension with the belief, held by many traditions, that the supremely real being is concerned for the salvation of all rational creatures. How can this he so if, through no fault of their own, most creatures cannot come to know the truth and thereby attain salvation?
