when it aims at the right kind of product, and when the means it adopts are well adapted to secure the intended result and are applied intelligently, consistently and persistently. Education is, thus, a definitely personal work, and will vary between wide extremes of effectiveness and worth in any given society. For in all times and places there are wide differences in virtue, wisdom and capacity among those who have in their hands the care and nurture of the young. But the inference that, therefore, no comparative estimate of the education of different times and places can be made would be fallacious. For, despite all differences in conception and efficiency among individual educators, each expresses, more or less perfectly and clearly, the common conception and energy of his age and country. As these rise or fall the general level of the actual educative practice rises or sinks with them. The first essential for successful educative effort is, then, that the community as a whole should have a true estimate of the nature and value of education. I. EDUCATIONAL THEORY In any comparative estimate of different places and times, as tested by the standard just given, it must be borne in mind that, except in the most general and abstract form, we cannot speak of an ideally best education. Looking at the individual to be educated, we may say with Plato that the aim of education is "to develop in the body and in the soul all the beauty and all the perfection of which they are capable," but this leaves quite undecided the nature and form of that beauty and perfection, and on such points there has never been universal agreement at any one time, while successive ages have shown marked differences of estimate. We get nearer to the point when we reflect that individual beauty and perfection are shown, and only shown, in actual life, and that such life has to be lived under definite conditions of time, place, culture, religion, national aspirations and mastery over material conditions. Perfection of life, then, in the Athens of the age of Plato would show a very different form from that which it would take in the London or Paris of to-day. So an individualistic statement of the purpose of education leads on analysis to considerations that are not, in themselves, individualistic. The personal life is throughout a relation between individual promptings to activity and the environment in which alone such promptings can, by being actualized, become part of life. And the perfection of the life is to be sought in the perfection of the relations thus established. So far, then, as any conception of education can give guidance to the actual process it must be relative in every way to the state of development of the society in which it is given. Indeed, looked at in the mass, education may be said to be the efforts made by the community to impose its culture upon the growing generation. Here again is room for difference. The culture in question
