The importance of having words by which concepts may be distinguished and isolated from one another will become clearer by a brief reminder of the nature of reflection. Thinking is in large part (as will be discussed in detail in chapter XIII) concerned with the breaking-up of an experience into its significant elements. But experience begins with objects, and so far as perceptual experience is concerned, ends there. We perceive objects, not qualities, actions, or ideas apart from objects. And the elements into which thinking analyzes an experience are never present, save in connection with, as parts of, a sensibly perceived object. Thus we never perceive whiteness save in white objects; warmth save in warm objects; red save in red objects. We never, for that matter, perceive so abstract a thing as an "object." We experience red houses or red flags; white flowers, white shoes, white paper; warm stoves, warm soup, and warm plates. Even houses and stoves and shoes are, in a sense, abstractions. No two of these are ever alike. But it is of the highest importance for us to have some means of identifying and preserving in memory the significant resemblances between our experiences. Else we should be, as it were, utterly astounded every time we saw a chair or a table or a fork. Though they may, in each case in which we experience them, differ in detail, chairs, tables, forks have certain common features which we can "abstract" from the gross total experience, and by a word or "term," define, record, communicate, and recall. The advantage of a precise technical vocabulary over a loose "popular" one is that we can by means of the former more accurately single out the specific and important elements of an experience and distinguish them from one another. The common nouns, or "general names" in a language indicate to what extent and in what manner that language, through some or other of its users, classifies its experiences. Highly developed languages make it possible to classify similarities not easily detected in crude experience. They make it possible to identify other things than merely directly sensed objects. In primitive languages experience is described and classified only in so far as it is perceptual. In other words, primitive languages have names for objects only, not for ideas, qualities, or relations. Thus it is impossible in some Indian languages to express the concept of a "brother" by the same word, unless the "brother" is in every case in the same identical circumstances. One cannot use the same word for "man" in different relations: "man-eating," "man-sleeping," "man-standing-here," and "man-running-there" would all be separate compound words. Among the Fuegians there is one word which means "to look at one another, hoping that each will offer to do something which both parties desire but are unwilling to do."[1] Marett writes in this connection: [Footnote 1: Marett: _Anthropology_, p. 140.]
