The isolation of aims and values which we have been considering leads to opposition between them. Probably the most deep-seated antithesis which has shown itself in educational history is that between education in preparation for useful labor and education for a life of leisure. The bare terms 'useful labor' and 'leisure' confirm the statement already made that the segregation and conflict of values are not self-inclosed, but reflect a division within social life. Were the two functions of gaining a livelihood by work and enjoying in a cultivated way the opportunities of leisure, distributed equally among the different members of a community, it would not occur to any one that there was any conflict of educational agencies and aims involved. It would be self-evident that the question was how education could contribute most effectively to both. And while it might be found that some materials of instruction chiefly accomplished one result and other subject matter the other, it would be evident that care must be taken to secure as much overlapping as conditions permit; that is, the education which had leisure more directly in view should indirectly reënforce as much as possible the efficiency and the enjoyment of work, while that aiming at the latter should produce habits of emotion and intellect which would procure a worthy cultivation of leisure.

These general considerations are amply borne out by the historical development of educational philosophy. The separation of liberal education from professional and industrial education goes back to the time of the Greeks, and was formulated expressly on the basis of a division of classes into those who had to labor for a living and those who were relieved from this necessity. The conception that liberal education, adapted to men in the latter class, is intrinsically higher than the servile training given to the latter class reflected the fact that one class was free and the other servile in its social status. The latter class labored not only for its own subsistence, but also for the means which enabled the superior class to live without personally engaging in occupations taking almost all the time and not of a nature to engage or reward intelligence.

That a certain amount of labor must be engaged in goes without saying. Human beings have to live and it requires work to supply the resources of life. Even if we insist that the interests connected with getting a living are only material and hence intrinsically lower than those connected with enjoyment of time released from labor, and even if it were admitted that there is something engrossing and insubordinate in material interests which leads them to strive to usurp the place belonging to the higher ideal interests, this would not—barring the fact of socially divided classes—lead to neglect of the kind of education which trains men for the useful pursuits. It would rather lead to scrupulous care for them, so that men were trained to be efficient in them and yet to keep them in their place; education would see to it that we avoided the evil results which flow from their being allowed to flourish in obscure purlieus of neglect. Only when a division of these interests coincides with a division of an inferior and a superior social class will preparation for useful work be looked down upon with contempt as an unworthy thing: a fact which prepares one for the conclusion that the rigid identification of work with material interests, and leisure with ideal interests is itself a social product.

The educational formulations of the social situation made over two thousand years ago have been so influential and give such a clear and logical recognition of the implications of the division into laboring and leisure classes, that they deserve especial note. According to them, man occupies the highest place in the scheme of animate existence. In part, he shares the constitution and functions of plants and animals—nutritive, reproductive, motor or practical. The distinctively human function is reason existing for the sake of beholding the spectacle of the universe. Hence the truly human end is the fullest possible of this distinctive human prerogative. The life of observation, meditation, cogitation, and speculation pursued as an end in itself is the proper life of man. From reason moreover proceeds the proper control of the lower elements of human nature—the appetites and the active, motor, impulses. In themselves greedy, insubordinate, lovers of excess, aiming only at their own satiety, they observe moderation—the law of the mean—and serve desirable ends as they are subjected to the rule of reason.

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. 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.

To these two modes of occupation, with their distinction of servile and free activities (or "arts") correspond two types of education: the base or mechanical and the liberal or intellectual. Some persons are trained by suitable practical exercises for capacity in doing things, for ability to use the mechanical tools involved in turning out physical commodities and rendering personal service. This training is a mere matter of habituation and technical skill; it operates through repetition and assiduity in application, not through awakening and nurturing thought. Liberal education aims to train intelligence for its proper office: to know. The less this knowledge has to do with practical affairs, with making or producing, the more adequately it engages intelligence. So consistently does Aristotle draw the line between menial and liberal education that he puts what are now called the "fine" arts, music, painting, sculpture, in the same class with menial arts so far as their practice is concerned. They involve physical agencies, assiduity of practice, and external results. In discussing, for example, education in music he raises the question how far the young should be practiced in the playing of instruments. His answer is that such practice and proficiency may be tolerated as conduce to appreciation; that is, to understanding and enjoyment of music when played by slaves or professionals. When professional power is aimed at, music sinks from the liberal to the professional level. One might then as well teach cooking, says Aristotle. Even a liberal concern with the works of fine art depends upon the existence of a hireling class of practitioners who have subordinated the development of their own personality to attaining skill in mechanical execution. The higher the activity the more purely mental is it; the less does it have to do with physical things or with the body. The more purely mental it is, the more independent or self-sufficing is it.

These last words remind us that Aristotle again makes a distinction of superior and inferior even within those living the life of reason. For there is a distinction in ends and in free action, according as one's life is merely accompanied by reason or as it makes reason its own medium. That is to say, the free citizen who devotes himself to the public life of his community, sharing in the management of its affairs and winning personal honor and distinction, lives a life accompanied by reason. But the thinker, the man who devotes himself to scientific inquiry and philosophic speculation, works, so to speak, in reason, not simply by it. Even the activity of the citizen in his civic relations, in other words, retains some of the taint of practice, of external or merely instrumental doing. This infection is shown by the fact that civic activity and civic excellence need the help of others; one cannot engage in public life all by himself. But all needs, all desires, imply, in the philosophy of Aristotle, a material factor; they involve lack, privation; they are dependent upon something beyond themselves for completion. A purely intellectual life, however, one carries on by himself, in himself; such assistance as he may derive from others is accidental, rather then intrinsic. In knowing, in the life of theory, reason finds its own full manifestation; knowing for the sake of knowing irrespective of any application is alone independent, or self-sufficing. Hence only the education that makes for power to know as an end in itself, without reference to the practice of even civic duties, is truly liberal or free.
