Something to a like effect is to be said of other traits that go to make up the barbarian character. For the purposes of economic theory, these further barbarian traits may be taken as concomitant variations of that predaceous temper of which prowess is an expression. In great measure they are not primarily of an economic character, nor do they have much direct economic bearing. They serve to indicate the stage of economic evolution to which the individual possessed of them is adapted. They are of importance, therefore, as extraneous tests of the degree of adaptation of the character in which they are comprised to the economic exigencies of today, but they are also to some extent important as being aptitudes which themselves go to increase or diminish the economic serviceability of the individual. As it finds expression in the life of the barbarian, prowess manifests itself in two main directions--force and fraud. In varying degrees these two forms of expression are similarly present in modern warfare, in the pecuniary occupations, and in sports and games. Both lines of aptitudes are cultivated and strengthened by the life of sport as well as by the more serious forms of emulative life. Strategy or cunning is an element invariably present in games, as also in warlike pursuits and in the chase. In all of these employments strategy tends to develop into finesse and chicanery. Chicanery, falsehood, browbeating, hold a well-secured place in the method of procedure of any athletic contest and in games generally. The habitual employment of an umpire, and the minute technical regulations governing the limits and details of permissible fraud and strategic advantage, sufficiently attest the fact that fraudulent practices and attempts to overreach one's opponents are not adventitious features of the game. In the nature of the case habituation to sports should conduce to a fuller development of the aptitude for fraud; and the prevalence in the community of that predatory temperament which inclines men to sports connotes a prevalence of sharp practice and callous disregard of the interests of others, individually and collectively. Resort to fraud, in any guise and under any legitimation of law or custom, is an expression of a narrowly self-regarding habit of mind. It is needless to dwell at any length on the economic value of this feature of the sporting character.
