Since the school of to-day is organized and supported by the state as a special corporate body designed to carry on the work of education, it becomes of public interest to know the particular purpose served through the maintenance of such a state institution. We have already seen that the school seeks to interpret the civilized life of the community, to abstract out of it certain elements, and to arrange them in systematic or scientific order as a curriculum of study, and finally to give the child control of this experience, or knowledge. We have attempted to show further that by this means education so increases the effectiveness of the conscious reactions of the child and so modifies his instincts and his habits as to add to his social efficiency. As, however, many divergent and incomplete views are held by educators and others as to the real purpose of public instruction, it will be well at this stage to consider briefly some of the most important types of these theories. =Aristocratic View.=--It may be noted that the experience, or knowledge, represented in the curriculum cannot exist outside of the knowing mind. In other words, arithmetic, grammar, history, geography, etc., are not something existing apart from mind, but only as states of consciousness. Text-books, for instance, do not contain knowledge but merely symbols of knowledge, which would have no significance and give no light without a mind to interpret them. Some, therefore, hold that the school, in seeking to translate this social experience into the consciousness of the young, should have as its aim merely to conserve for the future the intellectual and moral achievements of the present and the past. This they say demands of the school only that it produce an intellectual priesthood, or a body of scholars, who may conserve wisdom for the light and guidance of the whole community. Thus arises the aristocratic view of the purpose of education, which sees no justification in the state attempting to provide educational opportunities for all of its members, but holds rather that education is necessary only for the leaders of society. =Democratic View.=--Against the above view, it is claimed by others that, while public education should undoubtedly be conducted for the benefit of the state as a whole; yet, since a chain cannot be stronger than its weakest link, the efficiency of the state must be measured by that of its individual units. The state, therefore, must aim, by means of education, to add to its own efficiency by adding to that of each and all of its members. This demands, however, that every individual should be able to meet in an intelligent way such situations as he is likely to encounter in his community life. Although carried on, therefore, for the good of the state, yet education should be democratic, or universal, and should fit every individual to become a useful member of society.
