Is natural realism, permissible in logic, refuted then by empirical fact? Do our minds have no object in common after all?
Yes, they certainly have Space in common. On pragmatic principles we are obliged to predicate sameness wherever we can predicate no assignable point of difference. If two named things have every quality and function indiscernible, and are at the same time in the same place, they must be written down as numerically one thing under two different names. But there is no test discoverable, so far as I know, by which it can be shown that the place occupied by your percept of Memorial Hall differs from the place occupied by mine. The percepts themselves may be shown to differ; but if each of us be asked to point out where his percept is, we point to an identical spot. All the relations, whether geometrical or causal, of the Hall originate or terminate in that spot wherein our hands meet, and where each of us begins to work if he wishes to make the Hall change before the other’s eyes. Just so it is with our bodies. That body of yours which you actuate and feel from within must be in the same spot as the body of yours which I see or touch from without. ‘There’ for me means where I place my finger. If you do not feel my finger’s contact to be ‘there’ in my sense, when I place it on your body, where then do you feel it? Your inner actuations of your body meet my finger there: it is there that you resist its push, or shrink back, or sweep the finger aside with your hand. Whatever farther knowledge either of us may acquire of the real constitution of the body which we thus feel, you from within and I from without, it is in that same place that the newly conceived or perceived constituents have to be located, and it is through that space that your and my mental intercourse with each other has always to be carried on, by the mediation of impressions which I convey thither, and of the reactions thence which those impressions may provoke from you.
In general terms, then, whatever differing contents our minds may eventually fill a place with, the place itself is a numerically identical content of the two minds, a piece of common property in which, through which, and over which they join. The receptacle of certain of our experiences being thus common, the experiences themselves might some day become common also. If that day ever did come, our thoughts would terminate in a complete empirical identity, there would be an end, so far as those experiences went, to our discussions about truth. No points of difference appearing, they would have to count as the same.
VII. Conclusion
With this we have the outlines of a philosophy of pure experience before us. At the outset of my essay, I called it a mosaic philosophy. In actual mosaics the pieces are held together by their bedding, for which bedding the Substances, transcendental Egos, or Absolutes of other philosophies may be taken to stand. In radical empiricism there is no bedding; it is as if the pieces clung together by their edges, the transitions experienced between them forming their cement. Of course such a metaphor is misleading, for in actual experience the more substantive and the more transitive parts run into each other continuously, there is in general no separateness needing to be overcome by an external cement; and whatever separateness is actually experienced is not overcome, it stays and counts as separateness to the end. But the metaphor serves to symbolize the fact that Experience itself, taken at large, can grow by its edges. That one moment of it proliferates into the next by transitions which, whether conjunctive or disjunctive, continue the experiential tissue, can not, I contend, be denied. Life is in the transitions as much as in the terms connected; often, indeed, it seems to be there more emphatically, as if our spurts and sallies forward were the real firing-line of the battle, were like the thin line of flame advancing across the dry autumnal field which the farmer proceeds to burn. In this line we live prospectively as well as retrospectively. It is ‘of’ the past, inasmuch as it comes expressly as the past’s continuation; it is ‘of’ the future in so far as the future, when it comes, will have continued it.
These relations of continuous transition experienced are what make our experiences cognitive. In the simplest and completest cases the experiences are cognitive of one another. When one of them terminates a previous series of them with a sense of fulfilment, it, we say, is what those other experiences ‘had in view.’ The knowledge, in such a case, is verified; the truth is ‘salted down.’ Mainly, however, we live on speculative investments, or on our prospects only. But living on things in posse is as good as living in the actual, so long as our credit remains good. It is evident that for the most part it is good, and that the universe seldom protests our drafts.
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.
