There are a great many religions being practiced as you read this sentence. Each has its way of interpreting and responding to the world. Expressed in rites and rituals, institutions and practices, each has a view of what there is—of the cosmos as a whole and of the role and status of persons in it. Taken seriously, these views have implications for most if not all of life. Some practice withdrawing from the world, looking internally into oneself for answers to questions as to what one is and how one may flourish. Others look to a community for such answers. Many if not all treat verbal traditions or oral texts, or both, as being at least helpful and more likely authoritative in terms of discerning a proper path in life. Among these religions, we will consider four examples. Each includes a view of what there is (metaphysics), of how it may be known (epistemology), and of what has deep value (value theory, including ethics). Our choices are cross-cultural and intended to be representative of two diverse sorts of religious traditions. No disrespect is intended to any religious tradition in this selection. The field is too vast to cover in one volume, and one cannot help being selective. The idea is to provide very diverse samples.
