Morris Ginsberg was continually preoccupied with examining the role of reason in ethics. His position on this has sometimes been misunderstood – occasionally strategically misunderstood. He charted and analysed the diversity of morals among societies, and between groups and individuals, but made a clear distinction between that recognition and assumption that ethics must be entirely relative. In consequence he was ready to take issue with those who propounded emotive theories of ethics, and those who were influenced, for example, by the work of cultural anthropologists to adopt the relativistic standpoint. Cultural relativism, however, does not entail moral relativism, as its opponents often claim in a straw-man argument.
