In this sense we at every moment can continue to believe in an existing _beyond_. It is only in special cases that our confident rush forward gets rebuked. The beyond must, of course, always in our philosophy be itself of an experiential nature. If not a future experience of our own or a present one of our neighbor, it must be a thing in itself in Dr. Prince's and Professor Strong's sense of the term--that is, it must be an experience _for_ itself whose relation to other things we translate into the action of molecules, ether-waves, or whatever else the physical symbols may be.[40] This opens the chapter of the relations of radical empiricism to panpsychism, into which I can not enter now.[41] The beyond can in any case exist simultaneously--for it can be experienced _to have existed_ simultaneously--with the experience that practically postulates it by looking in its direction, or by turning or changing in the direction of which it is the goal. Pending that actuality of union, in the virtuality of which the 'truth,' even now, of the postulation consists, the beyond and its knower are entities split off from each other. The world is in so far forth a pluralism of which the unity is not fully experienced as yet. But, as fast as verifications come, trains of experience, once separate, run into one another; and that is why I said, earlier in my article, that the unity of the world is on the whole undergoing increase. The universe continually grows in quantity by new experiences that graft themselves upon the older mass; but these very new experiences often help the mass to a more consolidated form. These are the main features of a philosophy of pure experience. It has innumerable other aspects and arouses innumerable questions, but the points I have touched on seem enough to make an entering wedge. In my own mind such a philosophy harmonizes best with a radical pluralism, with novelty and indeterminism, moralism and theism, and with the 'humanism' lately sprung upon us by the Oxford and the Chicago schools.[42] I can not, however, be sure that all these doctrines are its necessary and indispensable allies. It presents so many points of difference, both from the common sense and from the idealism that have made our philosophic language, that it is almost as difficult to state it as it is to think it out clearly, and if it is ever to grow into a respectable system, it will have to be built up by the contributions of many co-operating minds. It seems to me, as I said at the outset of this essay, that many minds are, in point of fact, now turning in a direction that points towards radical empiricism. If they are carried farther by my words, and if then they add their stronger voices to my feebler one, the publication of this essay will have been worth while. FOOTNOTES:
