The accounts given by travelers and observers of the morals of savages often present a perplexing contrariety of opinion. Some writers represent such people as absolutely without a moral sense, while others, as has already been remarked, hold them up as models for imitation by ourselves.

This contrariety in view results in part from an overlooking of the fact, just pointed out, that the moral goodness of the savage is largely a negative goodness, but chiefly from a failure to observe that the shield has two sides, that is to say, that savages have a double standard of morality—one standard regulating conduct within the social group, and another regulating conduct toward outsiders. Thus the command, “Thou shalt not kill,” means to the savage merely that he shall not kill a kinsman. It has in his mind no application to strangers, just as in our minds it has no application to animals.

It is the same in regard to lying. Savages in general have a high regard for truthfulness, as they understand this virtue. The plighted word among them is probably as sacredly kept as by the average of civilized men.[50] The repute of many savage folk for untruthfulness comes about from the fact that they do not think that a stranger has any right to the truth. “Among themselves,” writes Professor Starr of certain Congo tribes, “lying is not commended and truth is appreciated; but to deceive a stranger or a white man is commendable.”[51]

And so it is with stealing. Many uncivilized peoples are charged, and in a certain sense rightly, with making of theft a virtue. But it must be borne in mind that to the savage all persons not members of his own group are strangers and enemies. To steal from such is looked upon as a most praiseworthy exploit, while to steal from the members of one’s own group is regarded as a crime.[52]

This dual morality a survival in civilization

Now the important thing to note here is that this double morality is not something peculiar to the ethics of savages. This dualism runs through the whole moral history of the race, from the beginning to the present day, and constitutes one of the most important facts in the moral evolution of humanity. We too, like the savage, have our double standard of morality. The chief difference between us and the savage is this: he puts his double standard in practice all the time, we only occasionally. On occasion we fling aside our ordinary standard of morality, lift the savage’s war standard, and then like the savage lie and steal and kill—outside the tribe. To deceive the stranger now is commendable; to steal from him proper and right; to kill him a glorious exploit.

The great task of this century is to put an end to this scandal of civilization, to teach men the oneness and universality of the moral law, to get them to understand that right and wrong are right and wrong everywhere—outside the tribe as well as within.

The history of intertribal or international morality, then, is the record of its gradual assimilation to intratribal morality.[53] It is a record of how the stranger, the outsider, has come, or is coming, to be regarded as a kinsman, as a neighbor.

Hospitality, or the guest right; the first step beyond kinship morality[54]

The duty of hospitality, to which a high place is assigned in the code of primitive peoples, shows morality taking a step, the first step, beyond the narrow circle of the original group of kinsmen. As we have seen, in the beginning the feeling of duty and obligation is restricted to the little group of fellow clansmen or tribesmen. Every one outside this social circle is an enemy, and is without rights. But necessity forces men to go beyond the limits of their own clan or tribe, and in time there grows up a rule that the defenseless stranger shall be kindly received, entertained for a certain period, and then allowed to depart unharmed. It is easy to see how among clans scattered thinly over a wide territory, and where the earlier isolation is beginning to be broken by trade relations, this duty of hospitality should come to be regarded as a very sacred one, and the person of the stranger guest as inviolable.[55]
