Are we not, then, to take the attitude in education that _our culture is an experimental culture and represents an experimental civilization_? Although for us our ways and beliefs are final criteria of values in conduct, and we cannot hope or wish to free ourselves from them or to be guided by objective data, still we put them forward in the spirit of the enquirer, rather than as eternal principles. If this be right, we are not to guard our civilization jealously, hedge it about with national jealousy and bigotry but rather send our culture abroad on a mission. We are to understand and to teach the culture of every other nation sympathetically, trusting to our own foundations to hold firm. We must be so fortified in our own virtue that we shall not be afraid to send our spirit abroad to compete with whatever it shall meet in the old world or the new. This impulse to extend one's culture and philosophy is a deep one, and we believe it to be well-grounded. It has been said that the deepest impulse of British imperialism has been to extend English ways of thought throughout the world. There is truth in this. We may conclude also that unless a nation can feel sincerely that it is founded upon something that ought to endure and at least to have an opportunity to become universal, it lacks a growth principle and its civilization is not very secure. Certainly it lacks a great pedagogical advantage in all the internal work of education. The work of the intellectual leaders of a people is to uncover this kernel of sincere belief and worth, and strip nationalism at the same time of its encrustations of vanity and deception. There are, we may suppose, at the bottom of every nation's consciousness such sincere principles which are entitled to a fair field in the competition of the civilizations and the cultures of the world. We may be sure that there is Americanism that needs to be taught both for the sake of the world and for our own sake; something which constitutes our best contribution to an experimental world in which the over-emphasis of all sincere principles can ultimately do no harm. Americanism, with all the errors it may contain, and all the limitations it may have as a universal principle is better for us and for all, we may believe, than any dispassionate and well considered intellectualism, or a cosmopolitanism that is based upon a fear of provincialism. Let us be prepared, therefore, to go forth not to conquer but to participate in the life of the world.
