and power is to be English or German, American or Chinese—the mind of a civilized man or the mind of a savage—depends entirely on the social environment in which it is placed.
Take a number of infants born of the most highly civilized parents and transport them to an uninhabited country. Suppose them in some miraculous way to be sustained until they come of age to take care of themselves, and what would you have? More helpelss savages than any we know of. They would have fire to discover; the rudest tools and weapons to invent; language to construct. They would, in short, have to stumble their way to the simplest knowledge which the lowest races now possess, just as a child learns to walk. That they would in time do all these things I have not the slightest doubt, for all these possibilities are latent in the human mind just as the power of walking is latent in the human frame, but I do not believe they would do them any better or worse, any slower or quicker, than the children of barbarian parents placed in the same conditions. Given the very highest mental powers that exceptional individuals have ever displayed, and what could mankind be if one generation were separated from the next by an interval of time, as are the seventeen-year locusts? One such interval would reduce mankind, not to savagery, but to a condition compared with which savagery, as we know it, would seem civilization.
And, reversely, suppose a number of savage infants could, unknown to the mothers, for even this would be necessary to make the experiment a fair one, be substituted for as many children of civilization, can we suppose that growing up they would show any difference? I think no one who has mixed much with different peoples and classes will think so. The great lesson that is thus learned is that "human nature is human nature all the world over." And this lesson, too, may be learned
