10 DID THE INDIAN INVENT OR BORROW HIS CULTURE?
_American anthropologists usually deny that Old World cultures have influenced to any great extent the pre-Columbian development of the American Indian. We have set up for Aboriginal America a sort of_ ex post facto _Monroe Doctrine and are inclined to regard suggestions of alien influences as acts of aggression. This is probably a scientifically tenable position, although I am afraid it has often been maintained in part by an emotional bias—an “America for Americans” feeling._ —EARNEST A. HOOTON
We hope you have not been skipping the choice thoughts that we have placed at the beginning of chapters. Some of them are merely amusing, but certain ones make an important point. Such is the above remark from Hooton. It calls our attention to an unscientific emotionalism which often lies behind one of the dogmas of American archaeology.
This dogma is called the autochthonous origin of Indian cultures. It asserts that practically all the traits, discoveries, and inventions which Columbus, Cortes, and Pizarro found in the New World were homegrown products—importations barred. The question at issue between the friends and the opponents of this dogma is commonly expressed as Independent Invention versus Diffusion. But the phrasing is not quite accurate: it needs a little amplification. Anything invented by man is in a sense an independent invention. In the present case we are talking of an invention made in one center, the New World, independent of a similar invention in another center, the Old. We are concerned, not with independent invention, but with _parallel_ independent invention. “Diffusion” is still more inaccurate. Normally it means the gradual transfer of some trait or technique from one people to another, often through the intervention of a third or of a third and a fourth people. In the present discussion it is more a matter of a people’s carrying the trait or the technique to a new home. The question is not merely, “Did the Indian invent pottery?” or “Did the American Australoid invent the bull-roarer?” It is rather, “Did he invent it in the New World or the Old?” or “Did he invent it in the Old World and carry it to the New?” or “Did he invent it in the New World while another fellow invented it in the Old?”
