Professor Boas points out that civilized investigators traveling among savage tribes commit one serious fallacy in insisting on the inferiority of these primitive peoples. They are said to be irrational, for example, when they are quite logical in their way of dealing with the material which is at their disposal. Without any scientific information available, for example, anthropomorphism, or the tendency to interpret cosmic phenomena in human terms is quite natural and reasonable. Again: The difference in the mode of thought of primitive man and that of civilized man seems to consist largely in the difference of character of the traditional material with which the new perception associates itself. The instruction given to the child of primitive man is not based on centuries of experimentation, but consists of the crude experience of generations. When a new experience enters the mind of primitive man, the same process which we observe among civilized man brings about an entirely different series of associations, and therefore results in a different type of explanation. A sudden explosion will associate itself in his mind, perhaps, with the tales he has heard in regard to the mythical history of the world, and consequently will be accompanied by superstitious fear. When we recognize that neither among civilized men nor among primitive men the average individual carries to completion the attempt at causal explanation of phenomena, but carries it only so far as to amalgamate it with other previously known facts, we recognize that the result of the whole process depends entirely upon the character of the traditional material.[1] [Footnote 1: Boas: _Mind of Primitive Man_, pp. 203-04.] This may be illustrated by our immediate reactions of pleasure or disgust at customs or ideas that provoke directly opposite reactions among races reared in another tradition. Again primitive races have been accused of lacking self-control. The fact is that they exhibit self-control about matters which they regard as important, and lack of it in respect to matters which they regard as trivial. "When an Eskimo community is on the point of starvation, and their religious proscriptions forbid them to make use of the seals that are basking on the ice, the amount of self-control of the whole community which restrains them from killing those seals is certainly very great."[2] The case is similar with regard to nearly all the alleged inferiorities of primitive man, his improvidence, unreliability, and the like. In nearly every instance, it has been found that we are holding him to account for not being able to persist in courses of action which do not seem to him, with his training and education, worth persisting in, and for not conforming to standards which, given his background, are meaningless.
