The aim of efficiency (like any educational aim) must be included within the process of experience. When it is measured by tangible external products, and not by the achieving of a distinctively valuable experience, it becomes materialistic. Results in the way of commodities which may be the outgrowth of an efficient personality are, in the strictest sense, by-products of education: by-products which are inevitable and important, but nevertheless by-products. To set up an external aim strengthens by reaction the false conception of culture which identifies it with something purely "inner." And the idea of perfecting an "inner" personality is a sure sign of social divisions. What is called inner is simply that which does not connect with others--which is not capable of free and full communication. What is termed spiritual culture has usually been futile, with something rotten about it, just because it has been conceived as a thing which a man might have internally--and therefore exclusively. What one is as a person is what one is as associated with others, in a free give and take of intercourse. This transcends both the efficiency which consists in supplying products to others and the culture which is an exclusive refinement and polish. Any individual has missed his calling, farmer, physician, teacher, student, who does not find that the accomplishments of results of value to others is an accompaniment of a process of experience inherently worth while. Why then should it be thought that one must take his choice between sacrificing himself to doing useful things for others, or sacrificing them to pursuit of his own exclusive ends, whether the saving of his own soul or the building of an inner spiritual life and personality? What happens is that since neither of these things is persistently possible, we get a compromise and an alternation. One tries each course by turns. There is no greater tragedy than that so much of the professedly spiritual and religious thought of the world has emphasized the two ideals of self-sacrifice and spiritual self-perfecting instead of throwing its weight against this dualism of life. The dualism is too deeply established to be easily overthrown; for that reason, it is the particular task of education at the present time to struggle in behalf of an aim in which social efficiency and personal culture are synonyms instead of antagonists.
