John Dewey

Any student in a class on anthropology cannot help but notice the differences between various cultures of the world. Differences in dress, diet, and social norms are readily apparent. Such diversity in terms of ethics and justice are also easily seen and apparently shaped by the culture in which we live.

If there is no transcendent ethical standard, then often culture becomes the ethical norm for determining whether an action is right or wrong. This ethical system is known as cultural relativism.{1} Cultural relativism is the view that all ethical truth is relative to a specific culture. Whatever a cultural group approves is considered right within that culture. Conversely, whatever a cultural group condemns is wrong.

The key to cultural relativism is that right and wrong can only be judged relative to a specified society. There is no ultimate standard of right and wrong by which to judge culture.

A famous proponent of this view was John Dewey, often considered the father of American education. He taught that moral standards were like language and therefore the result of custom. Language evolved over time and eventually became organized by a set of principles known as grammar. But language also changes over time to adapt to the changing circumstances of its culture.

Likewise, Dewey said, ethics were also the product of an evolutionary process. There are no fixed ethical norms. These are merely the result of particular cultures attempting to organize a set of moral principles. But these principles can also change over time to adapt to the changing circumstances of the culture.

This would also mean that different forms of morality evolved in different communities. Thus, there are no universal ethical principles. What may be right in one culture would be wrong in another culture, and vice versa.

Although it is hard for us in the modern world to imagine, a primitive culture might value genocide, treachery, deception, even torture. While we may not like these traits, a true follower of cultural relativism could not say these are wrong since they are merely the product of cultural adaptation.

Clifford Gertz argued that culture must be seen as “webs of meaning” within which humans must live.{2} Gertz believed that “Humans are shaped exclusively by their culture and therefore there exists no unifying cross-cultural human characteristics.”{3}

As we will see, cultural relativism allows us to be tolerant toward other cultures, but it provides no basis to judge or evaluate other cultures and their practices.

William Graham Sumner

A key figure who expanded on Dewey’s ideas was William Graham Sumner of Yale University. He argued that what our conscience tells us depends solely upon our social group. The moral values we hold are not part of our moral nature, according to Sumner. They are part of our training and upbringing.

Sumner argued in his book, Folkways: “World philosophy, life policy, right, rights, and morality are all products of the folkways.”{4} In other words, what we perceive as conscience is merely the product of culture upon our minds through childhood training and cultural influence. There are no universal ethical principles, merely different cultural conditioning.

Sumner studied all sorts of societies (primitive and advanced), and was able to document numerous examples of cultural relativism. Although many cultures promoted the idea, for example, that a man could have many wives, Sumner discovered that in Tibet a woman was encouraged to have many husbands. He also described how some Eskimo tribes allowed deformed babies to die by being exposed to the elements. In the Fiji Islands, aged parents were killed.

Sumner believed that this diversity of moral values clearly demonstrated that culture is the sole determinant of our ethical standards. In essence, culture determines what is right and wrong. And different cultures come to different ethical conclusions.

Proponents of cultural relativism believe this cultural diversity proves that culture alone is responsible for our morality. There is no soul or spirit or mind or conscience. Moral relativists say that what we perceive as moral convictions or conscience are the byproducts of culture.

The strength of cultural relativism is that it allows us to withhold moral judgments about the social practices of another culture. In fact, proponents of cultural relativism would say that to pass judgment on another culture would be ethnocentric.

This strength, however, is also a major weakness. Cultural relativism excuses us from judging the moral practices of another culture. Yet we all feel compelled to condemn such actions as the Holocaust or ethnic cleansing. Cultural relativism as an ethical system, however, provides no foundation for doing so.

Melville Herskovits

Melville J. Herskovits wrote in Cultural Relativism: “Judgments are based on experience, and experience is interpreted by each individual in terms of his own enculturation.”{5} In other words, a person’s judgment about what is right and wrong is determined by their cultural experiences. This would include everything from childhood training to cultural pressures to conform to the majority views of the group. Herskovits went on to argue that even the definition of what is normal and abnormal is relative to culture.

He believed that cultures were flexible, and so ethical norms change over time. The standard of ethical conduct may change over time to meet new cultural pressures and demands. When populations are unstable and infant mortality is high, cultures value life and develop ethical systems to protect it. When a culture is facing overpopulation, a culture redefines ethical systems and even the value of life. Life is valuable and sacred in the first society. Mercy killing might become normal and acceptable in the second society.

Polygamy might be a socially acceptable standard for society. But later, that society might change its perspective and believe that it is wrong for a man to have more than one wife. Herskovits believed that whatever a society accepted or rejected became the standard of morality for the individuals in that society.

He believed that “the need for a cultural relativistic point of view has become apparent because of the realization that there is no way to play this game of making judgment across cultures except with loaded dice.”{6} Ultimately, he believed, culture determines our moral standards and attempting to compare or contrast cultural norms is futile.

In a sense, the idea of cultural relativism has helped encourage such concepts as multiculturalism and postmodernism. After all, if truth is created not discovered, then all truths created by a particular culture are equally true. This would mean that cultural norms and institutions should be considered equally valid if they are useful to a particular group of people within a culture.

And this is one of the major problems with a view of cultural relativism: you cannot judge the morality of another culture. If there is no objective standard, then someone in one culture does not have a right to evaluate the actions or morality of another culture. Yet in our hearts we know that certain things like racism, discrimination, and exploitation are wrong.

Evolutionary Ethics

Foundational to the view of cultural relativism is the theory of evolution. Since social groups experience cultural change with the passage of time, changing customs and morality evolve differently in different places and times.

Anthony Flew, author of Evolutionary Ethics, states his perspective this way: “All morals, ideas and ideals have been originated in the world; and that, having thus in the past been subject to change, they will presumably in the future too, for better or worse, continue to evolve.”{7} He denies the existence of God and therefore an objective, absolute moral authority. But he also believes in the authority of a value system.

His theory is problematic because it does not adequately account for the origin, nature, and basis of morals. Flew suggests that morals somehow originated in this world and are constantly evolving.

Even if we concede his premise, we must still ask, Where and when did the first moral value originate? Essentially, Flew is arguing that a value came from a non-value. In rejecting the biblical idea of a Creator whose character establishes a moral standard for values, Flew is forced to attempt to derive an ought from an is.

Evolutionary ethics rests upon the assumption that values are by nature constantly changing or evolving. It claims that it is of value that values are changing. But is this value changing?

If the answer to this question is no, then that would mean that moral values don’t have to always change. And if that is the case, then there could be unchanging values (known as absolute standards). However, if the value that values change is itself unchanging, then the view is self-contradictory.

Another form of evolutionary ethics is sociobiology. E. O. Wilson of Harvard University is a major advocate of sociobiology, and claims that scientific materialism will eventually replace traditional religion and other ideologies.{8}

According to sociobiology, human social systems have been shaped by an evolutionary process. Human societies exist and survive because they work and because they have worked in the past.

A key principle is the reproductive imperative.{9} The ultimate goal of any organism is to survive and reproduce. Moral systems exist because they ultimately promote human survival and reproduction.

Another principle is that all behavior is selfish at the most basic level. We love our children, according to this view, because love is an effective means of raising effective reproducers.

At the very least, sociobiology is a very cynical view of human nature and human societies. Are we really to believe that all behavior is selfish? Is there no altruism?

The Bible and human experience seem to strongly contradict this. Ray Bohlin’s article on the Probe Web site provides a detailed refutation of this form of evolutionary ethics.{10}

Evaluating Cultural Relativism

In attempting to evaluate cultural relativism, we should acknowledge that we could indeed learn many things from other cultures. We should never fall into the belief that our culture has all the answers. No culture has a complete monopoly on the truth. Likewise, Christians must guard against the assumption that their Christian perspective on their cultural experiences should be normative for every other culture.

However, as we have already seen, the central weakness of cultural relativism is its unwillingness to evaluate another culture. This may seem satisfactory when we talk about language, customs, even forms of worship. But this non-judgmental mindset breaks down when confronted by real evils such as slavery or genocide. The Holocaust, for example, cannot be merely explained away as an appropriate cultural response for Nazi Germany.

Cultural relativism faces other philosophical problems. For example, it is insufficient to say that morals originated in the world and that they are constantly changing. Cultural relativists need to answer how value originated out of non-value. How did the first value arise?

Fundamental to cultural relativism is a belief that values change. But if the value that values change is itself unchanging, then this theory claims an unchanging value that all values change and evolve. The position is self-contradictory.

Another important concern is conflict. If there are no absolute values that exist trans-culturally or externally to the group, how are different cultures to get along when values collide? How are we to handle these conflicts?

Moreover, is there ever a place for courageous individuals to challenge the cultural norm and fight against social evil? Cultural relativism seems to leave no place for social reformers. The abolition movement, the suffrage movement, and the civil rights movement are all examples of social movements that ran counter to the social circumstances of the culture. Abolishing slavery and providing rights to citizens are good things even if they were opposed by many people within society.

The Bible provides a true standard by which to judge attitudes and actions. Biblical standards can be used to judge individual sin as well as corporate sin institutionalized within a culture.

By contrast, culture cannot be used to judge right and wrong. A changing culture cannot provide a fixed standard for morality. Only God’s character, revealed in the Bible provides a reliable measure for morality.
