purpose this is indifferent. Thus we might think of the ideas and objects of our private world rather as corresponding to than as from the beginning identical with those which our fellow-men are occupied in constructing each within his own sphere of consciousness. And the same would be true even of the objects and contents within our own world, in as far as an act or effort would be required to maintain them, of the same kind with that which was originally required to construct them.... Thus the paradox of reference would become clearer. We should understand that we refer to a correspondence by means of a content. We should soften down the contradiction of saying that a name to meet which we have and can get nothing but an idea, nevertheless does not stand for that idea but for something else. We should be able to say that the name stands for those elements in the idea which correspond in all our separate worlds, and in our own world of yesterday and of today, considered as so corresponding. (Pp. 45, 46.)
According to this view, the idea obtains the universality which constitutes it an idea by a sort of process of elimination. It is like a composite photograph. It selects only the common elements in a large number of particular existences, and thus succeeds in representing, or referring to, all the particular existences which have gone to make it up. But when we come to consider the bearing which this view of universality, or generalized significance, has on our estimate of the knowledge-process, we feel that it has not solved the problem for us. In the first place, the idea in its existence is just as particular when regarded as made up of the common elements of many ideas as is any of the ideas whose elements are taken. A composite photograph is just as much a single photograph as any one of the photographs which are taken to compose it. The chasm between the particularity of the psychical image and the universality of its meaning is not bridged by regarding the content of the image as made up by eliminating unlike elements in a number of images. The stuff with which thought has to work is still nothing more than a particular psychical image, and the problem of what gives it its logical value as a general significance is still unsolved. Nor does it seem possible to find anything in the existence of the image which could account for its reference to something outside of itself. The fact of reference itself becomes an ultimate mystery.48
But even waiving this difficulty, the judgment must still appear truncated, if it really totally disregard a part of its content—i. e., the particular existence of the image as part of the judging consciousness. The theory holds that the particular existence of the image has no logical value. It is only its meaning, or general reference, which has logical value. But the image qua image is just as real as that to which it is supposed to refer. If the judgment really does ignore its existence, then it ignores a portion of the reality it attempts to represent, and stands self-confessed as a failure.49 At still another point, ideas, as Bosanquet represents them, prove to be unsatisfactory tools to use in the work of building up reality. In Bosanquet's words: "The meaning tyrannizes over the psychical image in another respect. Besides crushing out of sight its particular and exclusive existence, it also crushes out part of its content" (p. 74). The idea, as we use it, is not, as to content, a complete or accurate representation of anything real. To take Bosanquet's illustration:
Some one speaks to me of the Ægean sea, which I have never seen. He tells me that it is a deep blue sea under a cloudless sky, studded with rocky islands. The meanings of these words are a problem set to my thought. I have to meet him in the world of objective references, which as intelligent beings we have in common. How I do this is my own affair, and the precise images at my command will vary from day to day, and from minute to minute. It sounds simple to say that I combine my recollections of sea and sky at Torbay with those of the island-studded waters of Orkney or the Hebrides. Even so, there is much to adjust and to neglect; the red cliffs of Torbay, and the cloudy skies of the north. But then again, my recollections are already themselves symbolic ideas; the reference to Torbay or the Hebrides is itself a problem set to thought, and puts me upon the selection of index-elements in fugitive images that are never twice the same. I have first to symbolize the color of Torbay, using for the purpose any blue that I can call to mind, and fixing, correcting, subtracting from, the color so recalled, till I reduce it to a mere index quality; and then I have to deal in the same way with the meaning or significant idea so obtained, clipping and adjusting the qualities of Torbay till it seems to serve as a symbol of the Ægean. (Pp. 74, 75.)
And by the time all this is performed what sort of a representation of reality is the idea? Evidently a very poor and meager and fragmentary one.
It is so poor and fragmentary, that it cannot itself be that which is affirmed of reality. It must be some other fuller existence to be found in the world of meanings which is affirmed. And yet how the meager content of the idea succeeds in referring to the world of meanings, and acting as the instrument for referring a meaning to reality, is not at all clear. It seems impossible to explain reference intelligibly by the concept of a correspondence of contents.
The fundamental difficulty in the interpretation of the predicate is the same one that we encountered in the interpretation of the subject. If the predicate is to be affirmed of reality (and if it be not, it has no logical value), then it must, when affirmed, be in some sense an accurate representation of reality. But the predicate is an idea, and, moreover, an idea which is, both in its existence and in its meaning palpably the outcome of transformations wrought upon given sensory contents by the individual consciousness. Since the one point of contact with reality is in sensory experience, the more simple sensory experiences are reacted upon and worked over, the farther they recede from reality. The idea seems, therefore, in its very essence, a thing which never can be affirmed of reality. As image it is itself a reality, but not affirmed; as meaning it is that reality (the image) manipulated for individual ends. Why suppose that by distorting reality we get it in shape to affirm of reality? Moreover, the farther an idea is removed from immediate sensory experience—in other words, the more abstract it becomes—the less is the possibility of affirming it of reality. The final outcome of this point of view, if we adhere rigorously to its logic is that the more thinking we do, the less we know about the real world. Bosanquet avoids this conclusion by a pure act of faith. If knowledge is to be rescued, we must believe that the work done by consciousness upon the bits of reality given in sensory experience really does succeed in building up a knowledge of reality for us. As Bosanquet puts it: "The presentation of Reality, qualified by an ideal content, is one aspect of Subject and Predication; and my individual percipient consciousness determining itself by a symbolic idea is the other. That the latter is identified with the former follows from the claim of conscious thought that its nature is to know."50 (P. 83.)
To sum up the situation, Bosanquet starts out with the assumption that by knowledge we must mean knowledge of a world entirely independent of our ideas. If we fail to make this assumption, knowledge becomes merely a relation between ideas. But its whole importance seems to us to rest on the conviction that it does give us knowledge of a world which is what it is quite independently of our ideas about it, and cannot in any sense be modified by what we think about it. What knowledge does is to give us a copy or representation of the real world, whose value depends on the accuracy of the representation. And yet when we examine any individual knowing consciousness, the subject which appears within the judgment is never some portion of the world which exists outside of the knowing consciousness, but always some portion of the world which exists within the knowing consciousness, and which is constituted by the knowledge process. The predicate which is affirmed of reality is constantly found to derive its meaning, its generalized significance, not from its correspondence with, or reference to, the real world outside of the knowing consciousness, but from reference to a world of meanings, which consists in a sort of convention among rational beings—a world whose existence is distinctly within the knowing consciousness and not outside of it.51 Between the real world, as Bosanquet conceives it, and the world of knowledge, we find inserted on the side of the subject, the world as known to each of us, and on the side of the predicate, the objective world of meanings. Neither of these is the real world. Both of them are ideal, i. e., are constructions of the individual consciousness. We nowhere find any satisfactory explanation of how these ideal worlds are related to the real world. There is merely the assertion that we must believe that they represent the real world in order that we may believe that knowledge exists. But the fact remains that whenever we try to analyze and explain any particular judgment, what we find ourselves dealing with is always
