So it has been throughout all of the religious dispensations whose origins have survived in written records. Mendicancy, slavery, autocracy, conquest, ethnic prejudices and other undesirable features of social interaction have gone unchallenged—or been explicitly indulged—as religion sought to achieve reformations of behaviour that were considered more immediately essential at given stages in the advance of civilization. To condemn religion because any one of its successive dispensations failed to address the whole range of social wrongs would be to ignore everything that has been learned about the nature of human development. Inevitably, anachronistic thinking of this kind must also create severe psychological handicaps in appreciating and facing the requirements of one’s own time.
