All the aspects of any civilization arise out of a people’s religion: its politics, its economics, its arts, its sciences, even its simple crafts are the by-products of religious insights and a religious cult. For until human beings are tied together by some common faith, and share certain moral principles, they prey upon one another. In the common worship of the cult, a community forms. At the heart of every culture is a body of ethics, of distinctions between good and evil; and in the beginning, at least, those distinctions are founded upon the authority of revealed religion. Not until a people have come to share religious belief are they able to work together satisfactorily, or even to make sense of the world in which they find themselves. Thus all order—even the ideological order of modern totalist states, professing atheism—could not have come into existence, had it not grown out of general belief in truths that are perceived by the moral imagination.
