[Footnote: Extract from an article entitled 'A World of Pure Experience,' in the Journal of Philosophy, etc., September 29,1904.]
Throughout the history of philosophy the subject and its object have been treated as absolutely discontinuous entities; and thereupon the presence of the latter to the former, or the 'apprehension' by the former of the latter, has assumed a paradoxical character which all sorts of theories had to be invented to overcome. Representative theories put a mental 'representation,' 'image,' or 'content' into the gap, as a sort of intermediary. Commonsense theories left the gap untouched, declaring our mind able to clear it by a self-transcending leap. Transcendentalist theories left it impossible to traverse by finite knowers, and brought an absolute in to perform the saltatory act. All the while, in the very bosom of the finite experience, every conjunction required to make the relation intelligible is given in full. Either the knower and the known are:
(1) the self-same piece of experience taken twice over in different contexts; or they are
(2) two pieces of ACTUAL experience belonging to the same subject, with definite tracts of conjunctive transitional experience between them; or
(3) the known is a POSSIBLE experience either of that subject or another, to which the said conjunctive transitions WOULD lead, if sufficiently prolonged.
To discuss all the ways in which one experience may function as the knower of another, would be incompatible with the limits of this essay. I have treated of type 1, the kind of knowledge called perception, in an article in the Journal of Philosophy, for September 1, 1904, called 'Does consciousness exist?' This is the type of case in which the mind enjoys direct 'acquaintance' with a present object. In the other types the mind has 'knowledge-about' an object not immediately there. Type 3 can always formally and hypothetically be reduced to type 2, so that a brief description of that type will now put the present reader sufficiently at my point of view, and make him see what the actual meanings of the mysterious cognitive relation may be.
Suppose me to be sitting here in my library at Cambridge, at ten minutes' walk from 'Memorial Hall,' and to be thinking truly of the latter object. My mind may have before it only the name, or it may have a clear image, or it may have a very dim image of the hall, but such an intrinsic difference in the image makes no difference in its cognitive function. Certain extrinsic phenomena, special experiences of conjunction, are what impart to the image, be it what it may, its knowing office.
For instance, if you ask me what hall I mean by my image, and I can tell you nothing; or if I fail to point or lead you towards the Harvard Delta; or if, being led by you, I am uncertain whether the Hall I see be what I had in mind or not; you would rightly deny that I had 'meant' that particular hall at all, even tho my mental image might to some degree have resembled it. The resemblance would count in that case as coincidental merely, for all sorts of things of a kind resemble one another in this world without being held for that reason to take cognizance of one another.
On the other hand, if I can lead you to the hall, and tell you of its history and present uses; if in its presence I feel my idea, however imperfect it may have been, to have led hither and to be now TERMINATED; if the associates of the image and of the felt hall run parallel, so that each term of the one context corresponds serially, as I walk, with an answering term of the other; why then my soul was prophetic, and my idea must be, and by common consent would be, called cognizant of reality. That percept was what I MEANT, for into it my idea has passed by conjunctive experiences of sameness and fulfilled intention. Nowhere is there jar, but every later moment continues and corroborates an earlier one.
In this continuing and corroborating, taken in no transcendental sense, but denoting definitely felt transitions, LIES ALL THAT THE KNOWING OF A PERCEPT BY AN IDEA CAN POSSIBLY CONTAIN OR SIGNIFY. Wherever such transitions are felt, the first experience KNOWS the last one. Where they do not, or where even as possibles they can not, intervene, there can be no pretence of knowing. In this latter case the extremes will be connected, if connected at all, by inferior relations-bare likeness or succession, or by 'withness' alone. Knowledge of sensible realities thus comes to life inside the tissue of experience. It is MADE; and made by relations that unroll themselves in time. Whenever certain intermediaries are given, such that, as they develop towards their terminus, there is experience from point to point of one direction followed, and finally of one process fulfilled, the result is that THEIR STARTING-POINT THEREBY BECOMES A KNOWER AND THEIR TERMINUS AN OBJECT MEANT OR KNOWN. That is all that knowing (in the simple case considered) can be known-as, that is the whole of its nature, put into experiential terms. Whenever such is the sequence of our experiences we may freely say that we had the terminal object 'in mind' from the outset, even altho AT the outset nothing was there in us but a flat piece of substantive experience like any other, with no self-transcendency about it, and no mystery save the mystery of coming into existence and of being gradually followed by other pieces of substantive experience, with conjunctively transitional experiences between. That is what we MEAN here by the object's being 'in mind.' Of any deeper more real way of its being in mind we have no positive conception, and we have no right to discredit our actual experience by talking of such a way at all.
I know that many a reader will rebel at this. 'Mere intermediaries,' he will say, 'even tho they be feelings of continuously growing fulfilment, only SEPARATE the knower from the known, whereas what we have in knowledge is a kind of immediate touch of the one by the other, an "apprehension" in the etymological sense of the word, a leaping of the chasm as by lightning, an act by which two terms are smitten into one over the head of their distinctness. All these dead intermediaries of yours are out of each other, and outside of their termini still.'
But do not such dialectic difficulties remind us of the dog dropping his bone and snapping at its image in the water? If we knew any more real kind of union aliunde, we might be entitled to brand all our empirical unions as a sham. But unions by continuous transition are the only ones we know of, whether in this matter of a knowledge-about that terminates in an acquaintance, whether in personal identity, in logical prediction through the copula 'is,' or elsewhere. If anywhere there were more absolute unions, they could only reveal themselves to us by just such conjunctive results. These are what the unions are worth, these are all that we can ever practically mean by union, by continuity. Is it not time to repeat what Lotze said of substances, that to act like one is to be one? Should we not say here that to be experienced as continuous is to be really continuous, in a world where experience and reality come to the same thing? In a picture gallery a painted hook will serve to hang a painted chain by, a painted cable will hold a painted ship. In a world where both the terms and their distinctions are affairs of experience, conjunctions that are experienced must be at least as real as anything else. They will be 'absolutely' real conjunctions, if we have no transphenomenal absolute ready, to derealize the whole experienced world by, at a stroke.
So much for the essentials of the cognitive relation where the knowledge is conceptual in type, or forms knowledge 'about' an object. It consists in intermediary experiences (possible, if not actual) of continuously developing progress, and, finally, of fulfilment, when the sensible percept which is the object is reached. The percept here not only VERIFIES the concept, proves its function of knowing that percept to be true, but the percept's existence as the terminus of the chain of intermediaries CREATES the function. Whatever terminates that chain was, because it now proves itself to be, what the concept 'had in mind.'
