Dewey, John. Democracy and Education
Chapter Nine: “Natural Development and Social Efficiency as Aims”
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.
