The case of other kinds of sport is somewhat similar. Of these, athletic games are the best example. Prescriptive usage with respect to what forms of activity, exercise, and recreation are permissible under the code of reputable living is of course present here also. Those who are addicted to athletic sports, or who admire them, set up the claim that these afford the best available means of recreation and of "physical culture." And prescriptive usage gives countenance to the claim. The canons of reputable living exclude from the scheme of life of the leisure class all activity that can not be classed as conspicuous leisure. And consequently they tend by prescription to exclude it also from the scheme of life of the community generally. At the same time purposeless physical exertion is tedious and distasteful beyond tolerance. As has been noticed in another connection, recourse is in such a case had to some form of activity which shall at least afford a colorable pretense of purpose, even if the object assigned be only a make-believe. Sports satisfy these requirements of substantial futility together with a colorable make-believe of purpose. In addition to this they afford scope for emulation, and are attractive also on that account. In order to be decorous, an employment must conform to the leisure-class canon of reputable waste; at the same time all activity, in order to be persisted in as an habitual, even if only partial, expression of life, must conform to the generically human canon of efficiency for some serviceable objective end. The leisure-class canon demands strict and comprehensive futility, the instinct of workmanship demands purposeful action. The leisure-class canon of decorum acts slowly and pervasively, by a selective elimination of all substantially useful or purposeful modes of action from the accredited scheme of life; the instinct of workmanship acts impulsively and may be satisfied, provisionally, with a proximate purpose. It is only as the apprehended ulterior futility of a given line of action enters the reflective complex of consciousness as an element essentially alien to the normally purposeful trend of the life process that its disquieting and deterrent effect on the consciousness of the agent is wrought.
