These manifestations of the predatory temperament are all to be classed under the head of exploit. They are partly simple and unreflected expressions of an attitude of emulative ferocity, partly activities deliberately entered upon with a view to gaining repute for prowess. Sports of all kinds are of the same general character, including prize-fights, bull-fights, athletics, shooting, angling, yachting, and games of skill, even where the element of destructive physical efficiency is not an obtrusive feature. Sports shade off from the basis of hostile combat, through skill, to cunning and chicanery, without its being possible to draw a line at any point. The ground of an addiction to sports is an archaic spiritual constitution--the possession of the predatory emulative propensity in a relatively high potency, a strong proclivity to adventuresome exploit and to the infliction of damage is especially pronounced in those employments which are in colloquial usage specifically called sportsmanship. It is perhaps truer, or at least more evident, as regards sports than as regards the other expressions of predatory emulation already spoken of, that the temperament which inclines men to them is essentially a boyish temperament. The addiction to sports, therefore, in a peculiar degree marks an arrested development of the man's moral nature. This peculiar boyishness of temperament in sporting men immediately becomes apparent when attention is directed to the large element of make-believe that is present in all sporting activity. Sports share this character of make-believe with the games and exploits to which children, especially boys, are habitually inclined. Make-believe does not enter in the same proportion into all sports, but it is present in a very appreciable degree in all. It is apparently present in a larger measure in sportsmanship proper and in athletic contests than in set games of skill of a more sedentary character; although this rule may not be found to apply with any great uniformity. It is noticeable, for instance, that even very mild-mannered and matter-of-fact men who go out shooting are apt to carry an excess of arms and accoutrements in order to impress upon their own imagination the seriousness of their undertaking. These huntsmen are also prone to a histrionic, prancing gait and to an elaborate exaggeration of the motions, whether of stealth or of onslaught, involved in their deeds of exploit. Similarly in athletic sports there is almost invariably present a good share of rant and swagger and ostensible mystification--features which mark the histrionic nature of these employments. In all this, of course, the reminder of boyish make-believe is plain enough. The slang of athletics, by the way, is in great part made up of extremely sanguinary locutions borrowed from the terminology of warfare. Except where it is adopted as a necessary means of secret communication, the use of a special slang in any
