The assertion that moral claims differ across cultures is not merely an observation of varied customs, but a fundamental philosophical challenge to the very nature of ethics. From the sacredness of life in one society to the ritualistic sacrifice of animals in another, the outward expressions of morality are undeniably diverse. This essay argues that while surface-level moral practices exhibit significant cultural variation, there are underlying, potentially universal, ethical principles that inform these differences, suggesting a complex interplay between cultural context and shared human values.
One of the most prominent arguments for cultural variation in morality stems from the field of anthropology. Early ethnographic studies, such as those by Edward Westermarck in The Origin and Development of the Moral Ideas (1906-1908), cataloged a vast array of differing customs regarding marriage, property, and punishment. For instance, the concept of filial piety, deeply ingrained in Confucian societies where respect and obedience to elders are paramount, contrasts sharply with more individualistic Western societies where the autonomy of adult children is frequently prioritized. In some indigenous Amazonian tribes, infanticide was practiced under specific conditions, a practice viewed with universal horror in most modern cultures. These examples highlight how societal needs, environmental pressures, and historical developments can shape what is deemed morally acceptable or even obligatory.
However, to conclude solely from these variations that morality is entirely relative risks overlooking commonalities that bind human societies. Scholars like James Rachels have argued for a minimal set of universal moral rules necessary for any society to function. These often include prohibitions against gratuitous harm, requirements for care of the young, and norms of fairness in resource distribution. Consider the universal condemnation of unjustified murder. While the definition of "justified" might shift (e.g., capital punishment, warfare), the core principle of protecting life from arbitrary taking seems to be a near-universal moral intuition. Similarly, the concept of reciprocity, often encapsulated in the Golden Rule ("Do unto others as you would have them do unto you"), appears in myriad forms across diverse cultures, from ancient Egyptian texts to Buddhist teachings. This suggests that while the application of moral rules is culturally mediated, the underlying need for them is not.
The challenge then becomes understanding the relationship between these apparently divergent moral codes. Cultural relativism, in its strong form, posits that there is no objective standard by which to judge the morality of one culture against another. Yet, this stance can lead to problematic conclusions, such as being unable to criticize practices like slavery or genocide, simply because they are culturally sanctioned. A more nuanced approach, often termed "weak" or "contextual" relativism, acknowledges the influence of culture without abandoning the possibility of critical evaluation. This perspective suggests that moral judgments must be understood within their specific cultural context, but it does not preclude the possibility of identifying shared human needs or vulnerabilities that universal ethical principles might address. For example, the Zande people of Sudan, as documented by E.E. Evans-Pritchard in Witchcraft, Oracles, and Magic Among the Azande (1937), employed witchcraft to explain misfortune and administer justice. While the mechanism of witchcraft itself is not accepted in Western science, the underlying human need to understand causality and maintain social order is universal.
Ultimately, the differing moral claims across cultures reflect a dynamic interplay between the specific circumstances of a society and fundamental human requirements. Cultural practices are the historical and social expressions of attempts to live well, to maintain order, and to foster cooperation within a given environment. While these expressions can diverge dramatically, they often arise from a common ground of shared needs and capacities. Recognizing this complexity allows for a more sophisticated understanding of ethics, one that respects cultural diversity while still pursuing the possibility of universal moral progress and cross-cultural ethical understanding.
