A homely and familiar fact may serve to show that the predaceous impulse does not prevail in the same degree in all classes. Taken simply as a feature of modern life, the habit of carrying a walking-stick may seem at best a trivial detail; but the usage has a significance for the point in question. The classes among whom the habit most prevails--the classes with whom the walking-stick is associated in popular apprehension--are the men of the leisure class proper, sporting men, and the lower-class delinquents. To these might perhaps be added the men engaged in the pecuniary employments. The same is not true of the common run of men engaged in industry and it may be noted by the way that women do not carry a stick except in case of infirmity, where it has a use of a different kind. The practice is of course in great measure a matter of polite usage; but the basis of polite usage is, in turn, the proclivities of the class which sets the pace in polite usage. The walking-stick serves the purpose of an advertisement that the bearer's hands are employed otherwise than in useful effort, and it therefore has utility as an evidence of leisure. But it is also a weapon, and it meets a felt need of barbarian man on that ground. The handling of so tangible and primitive a means of offense is very comforting to any one who is gifted with even a moderate share of ferocity. The exigencies of the language make it impossible to avoid an apparent implication of disapproval of the aptitudes, propensities, and expressions of life here under discussion. It is, however, not intended to imply anything in the way of deprecation or commendation of any one of these phases of human character or of the life process. The various elements of the prevalent human nature are taken up from the point of view of economic theory, and the traits discussed are gauged and graded with regard to their immediate economic bearing on the facility of the collective life process. That is to say, these phenomena are here apprehended from the economic point of view and are valued with respect to their direct action in furtherance or hindrance of a more perfect adjustment of the human collectivity to the environment and to the institutional structure required by the economic situation of the collectivity for the present and for the immediate future. For these purposes the traits handed down from the predatory culture are less serviceable than might be. Although even in this connection it is not to be overlooked that the energetic aggressiveness and pertinacity of predatory man is a heritage of no mean value. The economic value--with some regard also to the social value in the narrower sense--of these aptitudes and propensities is attempted to be passed upon without reflecting on their value as seen from another point of view. When contrasted with the prosy mediocrity of the latter-day industrial scheme of life, and judged by the accredited
