repugnance is expressed as regards effort which brings gain without giving a product that is of human use, as, for example, the effort that goes into war, politics, or other employments of a similar nature. And there is commonly no avowed aversion to sports or other similar employments that yield neither a pecuni- ary gain nor a useful product. Still, the fact that a given line of effort is useless does not of itself save it from being odious, as is shown by the case of menial service ; much of this work serves no useful end, but it is none the less repugnant to all people of sensibility.
"The economic man," whose lineaments were traced in out- line by the classical economists and filled in by their caricaturists, is an anomaly in the animal word ; and yet, to judge by every- day popular expressions of inclination, the portrait is not seri- ously overdrawn. But if this economic man is to serve as a lay figure upon which to fit the garment of economic doctrines, it is incumbent upon the science to explain what are his limitations and how he has achieved his emancipation from the law of natural selection. His emancipation from the law is, indeed, more apparent than substantial. The difference in this respect between man and his sometime competitors in the struggle for survival lies not in a slighter but in a fuller adjustment of his propensities to the purposes of the life of the species. He dis- tanced them all in this respect long ago, and by so wide an interval that he is now able, without jeopardy to the life of the species, to play fast and loose with the spiritual basis of its sur- vival
Like other animals, man is an agent that acts in response to stimuli afforded by the environment in which he lives. Like other species, he is a creature of habit and propensity. But in a higher degree than other species, man mentally digests the content of the habits under whose guidance he acts, and appreciates the trend of these habits and propensities. He is in an eminent sense an intelligent agent. By selective necessity he is endowed with a proclivity for purposeful action. He is possessed of a discriminating sense of purpose, by force of which
