Facts which are not held together through theory call for labels. People who do not think in terms of relations are likely to be insistent upon names. Labels or names for sex disposition or acts are, as a matter of fact, very definite in the American vernacular. “Engaged,” “attentive,” “devoted,” “a married man,” “a man of family,” “a grass widow,” “a _good_ woman,” “a _bad_ woman”--there is no end to such tags. Again, intimacy between a man and a woman is referred definitely to the act of consummation, a sex relation is strictly classified according to whether or not it is physically consummated. In this attitude towards sex boundaries or captions may lie the explanation, incidentally, of what is a constant puzzle to the European visitor--the freedom of social intercourse allowed to the youth of opposite sexes. Since consummation only constitutes sexual intimacy in American opinion, and since consummation, it is assumed, is utterly out of the question, why raise barriers between boys and girls? The assumption that consummation is out of the question is, by and large, correct, which is still another puzzle. To this some clue may be found, I think, in our concluding discussion. Fondness for captions and for the sort of classification that is so likely to paralyze perception of the finer distinctions and to arrest thought, are natural enough in a child, learning language and so pressed upon by the multiplicity of phenomena that in self-protection he must make rough classifications and remain unaware of much. The old who are dying to life are also exclusive, and they, too, cling to formulas. Is American culture in the matter of sex childish and immature, as Americans imply when they refer to their “young country,” or is the culture representative of the aged; are Americans born old, as now and again a European critic asserts?
