In concluding, let me say that reference to experience seems at present to be the easiest way of realizing the continuities among subject-matters that are always getting split up into dualisms. A creation of a world of subsistences or essences which are quite other than the world of natural existences (which are other than natural existences adapted to the successful performance of inference) is in itself a technical matter, though a discouraging one to a philosopher expertly acquainted with all the difficulties which that view has generated from the time of Plato down. But the assistance which such a philosophy lends to the practical and current divorce of the "ideal" from the natural world makes it a thing to be dreaded for other than professional reasons. God only knows how many of the sufferings of life are due to a belief that the natural scene and operations of our life are lacking in ideal import, and to the consequent tendency to flee for the lacking ideal factors to some other world inhabited exclusively by ideals. That such a cut-off, ideal world is impotent for direction and control and change of the natural world follows as a matter of course. It is a luxury; it belongs to the "genteel tradition" of life, the persistence of an "upper" class given to a detached and parasitic life. Moreover, it places the scientific inquirer within that irresponsible class. If philosophers could aid in making it clear to a troubled humanity that ideals are continuous with natural events, that they but represent their possibilities, and that recognized possibilities form methods for a conduct which may realize them in fact, philosophers would enforce the sense of a social calling and responsibility. I do not say that pointing out the continuity and interaction of various attitudes and interests in experience is the only way of effecting this consummation. But for a large number of persons today it is the readiest way.
