If so eminent an authority as Curr can err so grievously, it is obvious that the testimony of other writers and casual observers must be accepted with extreme caution. Europeans and Americans are so accustomed to regard personal decorations as attempts to beautify the appearance that when they see them in savages there is a natural disposition to attribute them to the same motive. They do not realize that they are dealing with a most subtle psychological question. The chief source of confusion lies in their failure to distinguish between what is admired as a thing of beauty as such and what pleases them for other reasons. As Professor Sully has pointed out in his _Handbook of Psychology_ (337): "At the beginning of life there is no clear separation of what is beautiful from what is simply pleasing to the individual. As in the history of the race, so in that of the individual, the sense of beauty slowly extricates itself from pleasurable consciousness in general, and differentiates itself from the sense of what _is personally useful and agreeable_." Bearing in mind this very important distinction between what is beautiful and what is merely pleasing because of its being useful and agreeable, we see at once that the words "decorative," "ornamental," "attractive," "handsome," etc., are constantly used by writers on this subject in a misleading and question-begging way. We can hardly blame a man like Barrington for writing (11) that among the natives of Botany Bay "scars are, by both sexes, deemed highly ornamental"; but a scientific author who quotes such a sentence ought to be aware that the evidence did not justify Barrington in using any word but _pleasing_ in place of "ornamental," because the latter implies and takes for granted the esthetic sense, the existence of which is the very thing to be proved. This remark applies generally to the evidence of this kind which Westermarck has so industriously collected, and which, on account of this undiscriminating, question-begging character, is entirely worthless. In all these cases the fact is overlooked that the "decorations" of one sex may be agreeable to the other for reasons that have nothing to do with the sense of beauty.
