Such is the situation as an affair of theoretical psychology and as most adequately stated by Aristotle. But this state of things is reflected in the constitution of classes of men and hence in the organization of society. Only in a comparatively small number is the function of reason capable of operating as a law of life. In the mass of people, vegetative and animal functions dominate. Their energy of intelligence is so feeble and inconstant that it is constantly overpowered by bodily appetite and passion. Such persons are not truly ends in themselves, for only reason constitutes a final end. Like plants, animals and physical tools, they are means, appliances, for the attaining of ends beyond themselves, although unlike them they have enough intelligence to exercise a certain discretion in the execution of the tasks committed to them. Thus by nature, and not merely by social convention, there are those who are slaves--that is, means for the ends of others. 1 The great body of artisans are in one important respect worse off than even slaves. Like the latter they are given up to the service of ends external to themselves; but since they do not enjoy the intimate association with the free superior class experienced by domestic slaves they remain on a lower plane of excellence. Moreover, women are classed with slaves and craftsmen as factors among the animate instrumentalities of production and reproduction of the means for a free or rational life. Individually and collectively there is a gulf between merely living and living worthily. In order that one may live worthily he must first live, and so with collective society. The time and energy spent upon mere life, upon the gaining of subsistence, detracts from that available for activities that have an inherent rational meaning; they also unfit for the latter. Means are menial, the serviceable is servile. The true life is possible only in the degree in which the physical necessities are had without effort and without attention. Hence slaves, artisans, and women are employed in furnishing the means of subsistence in order that others, those adequately equipped with intelligence, may live the life of leisurely concern with things intrinsically worth while.
