deepening of intellectual insight—surely cultural values—also in the same degree renders what is learned limited in its use. Not that it makes it wholly unavailable but that its applicability is restricted to routine activities carried on under the supervision of others. Narrow modes of skill cannot be made useful beyond themselves; any mode of skill which is achieved with deepening of knowledge and perfecting of judgment is readily put to use in new situations and is under personal control. It was not the bare fact of social and economic utility which made certain activities seem servile to the Greeks but the fact that the activities directly connected with getting a livelihood were not, in their days, the expression of a trained intelligence nor carried on because of a personal appreciation of their meaning. So far as farming and the trades were rule-of-thumb occupations and so far as they were engaged in for results external to the minds of agricultural laborers and mechanics, they were illiberal—but only so far. The intellectual and social context has now changed. The elements in industry due to mere custom and routine have become subordinate in most economic callings to elements derived from scientific inquiry. The most important occupations of to-day represent and depend upon applied mathematics, physics, and chemistry. The area of the human world influenced by economic production and influencing consumption has been so indefinitely widened that geographical and political considerations of an almost infinitely wide scope enter in. It was natural for Plato to deprecate the learning of geometry and arithmetic for practical ends, because as matter of fact the practical uses to which they were put were few, lacking in content and mostly mercenary in quality. But as their social uses have increased and enlarged, their liberalizing or 'intellectual' value and their practical value approach the same limit.
Doubtless the factor which chiefly prevents our full recognition and employment of this identification is the conditions
