In popular apprehension there is much that is admirable in the type of manhood which the life of sport fosters. There is self-reliance and good-fellowship, so termed in the somewhat loose colloquial use of the words. From a different point of view the qualities currently so characterized might be described as truculence and clannishness. The reason for the current approval and admiration of these manly qualities, as well as for their being called manly, is the same as the reason for their usefulness to the individual. The members of the community, and especially that class of the community which sets the pace in canons of taste, are endowed with this range of propensities in sufficient measure to make their absence in others felt as a shortcoming, and to make their possession in an exceptional degree appreciated as an attribute of superior merit. The traits of predatory man are by no means obsolete in the common run of modern populations. They are present and can be called out in bold relief at any time by any appeal to the sentiments in which they express themselves--unless this appeal should clash with the specific activities that make up our habitual occupations and comprise the general range of our everyday interests. The common run of the population of any industrial community is emancipated from these, economically considered, untoward propensities only in the sense that, through partial and temporary disuse, they have lapsed into the background of sub-conscious motives. With varying degrees of potency in different individuals, they remain available for the aggressive shaping of men's actions and sentiments whenever a stimulus of more than everyday intensity comes in to call them forth. And they assert themselves forcibly in any case where no occupation alien to the predatory culture has usurped the individual's everyday range of interest and sentiment. This is the case among the leisure class and among certain portions of the population which are ancillary to that class. Hence the facility with which any new accessions to the leisure class take to sports; and hence the rapid growth of sports and of the sporting sentient in any industrial community where wealth has accumulated sufficiently to exempt a considerable part of the population from work.
