Final answer:
Under ethical relativism, if two cultures differ in their moral assessments of an action, both assessments would be considered valid within their respective cultures.
Step-by-step explanation:
Under ethical relativism, if an African culture and an Eastern Asian culture differ as to the morality of a particular action, both actions would be viewed as ethical. According to normative ethical relativism, each culture has its own ideas about ethics and morality. The theory claims that the moral rightness and wrongness of actions varies from society to society and that there are no universally valid moral principles.
Therefore, if two cultures differ in their moral assessments of an action, both assessments would be considered valid within their respective cultures. For example, if African culture considers a certain action to be moral while Eastern Asian culture considers the same action to be immoral, both actions would be viewed as ethical within their respective cultures under ethical relativism.
