From this point of view the greater sublimity traditionally attributed to the metaphysical inquiry, the grubbing inquiry, entirely disappears. If we could know what causation really and transcendentally is in itself, the only _use_ of the knowledge would be to help us to recognize an actual cause when we had one, and so to track the future course of operations more intelligently out. The mere abstract inquiry into causation's hidden nature is not more sublime than any other inquiry equally abstract. Causation inhabits no more sublime level than anything else. It lives, apparently, in the dirt of the world as well as in the absolute, or in man's unconquerable mind. The worth and interest of the world consists not in its elements, be these elements things, or be they the conjunctions of things; it exists rather in the dramatic outcome of the whole process, and in the meaning of the succession stages which the elements work out. My colleague and master, Josiah Royce, in a page of his review of Stout's _Analytic Psychology_, in _Mind_ for 1897, has some fine words on this point with which I cordially agree. I cannot agree with his separating the notion of efficacy from that of activity altogether (this I understand to be one contention of his), for activities are efficacious whenever they are real activities at all. But the inner nature both of efficacy and of activity are superficial problems, I understand Royce to say; and the only point for us in solving them would be their possible use in helping us to solve the far deeper problem of the course and meaning of the world of life. Life, says our colleague, is full of significance, of meaning, of success and of defeat, of hoping and of striving, of longing, of desire, and of inner value. It is a total presence that embodies worth. To live our own lives better in this presence is the true reason why we wish to know the elements of things; so even we psychologists must end on this pragmatic note.
