Bosanquet sums up the section of the introduction on knowledge and its content, truth, with the following paragraph:
The real world for every individual is thus emphatically his world; an extension and determination of his present perception, which perception is to him not indeed reality as such, but his point of contact with reality as such. Thus in the enquiry which will have to be undertaken as to the logical subject of the judgment, we shall find that the subject, however it may shift, contract, and expand, is always in the last resort some greater or smaller element of this determinate reality, which the individual has constructed by identifying significant ideas with that world of which he has assurance through his own perceptive experience. In analyzing common judgment it is ultimately one to say that I judge and that the real world for me, my real world, extends itself, or maintains its organized extension. This is the ultimate connection by which the distinction of subject and predication is involved in the act of affirmation or enunciation which is the differentia of judgment. (Pp. 3, 4).
Here the subject of the judgment appears as an element of a reality which the individual has constructed by identifying significant ideas with that world of which he has assurance through his own perceptive experience. But the very point with reference to the subject of the judgment previously emphasized is that it is not and cannot be something which the individual has constructed. The subject of the judgment must be reality, and reality does not consist of ideas, even if it be determined by them. It does not mend matters to explain that the individual has constructed his real world by identifying significant ideas with that world of which he has assurance through his own perceptive experiences, because, as we have seen, "the individual's perceptive experiences" either turn out to be merely similar mental constructions made at a prior time, so that nothing is gained by attaching to them, or else they mean once more the mere shock of contact which is supposed to give assurance that some sort of reality exists, but which gives no assurance of what it is. That and what, this and thisness still remain detached. When he talks of the real world for any individual we are left entirely in the dark as to what the relation between the real world as it is for any individual and the real world as it is for itself may be, or how the individual is to gain any assurance that the real world as it is for him represents the real world as it is for itself.
Another attempt at a reconciliation of these opposing views leaves us no better satisfied. The passage is as follows:
The real world, as a definite organized system, is for me an extension of this present sensation and self-feeling by means of judgment, and it is the essence of judgment to effect and sustain such an extension. It makes no essential difference whether the ideas whose content is pronounced to be an attribute of reality appear to fall within what is given in perception, or not. We shall find hereafter that it is vain to attempt to lay down boundaries between the given and its extension. The moment we try to do this we are on the wrong track. The given and its extension differ not absolutely but relatively; they are continuous with each other, and the metaphor by which we speak of an extension conceals from us that the so-called "given" is no less artificial than that by which it is extended. It is the character and quality of being directly in contact with sense-perception, not any fixed datum of content, that forms the constantly shifting center of the individual's real world, and spreads from that center over every extension which the system of reality receives from judgment. (P. 77.)
In this passage by the "given" he evidently means the content of sensory experience, the thisness, the what. It is, as he says, of the same stuff as that by which it is extended. Both the given and that by which it is extended are artificial in the sense of not being real according to Bosanquet's interpretation of reality; they are ideas. But if all this is admitted, what becomes of the possibility of knowledge? Bosanquet undertakes to rescue it by assuring us again that it is the character and quality of being directly in contact with sense-perception, not any fixed datum of content, that forms the center of the individual's real world and gives the stamp of reality to his otherwise ideal extension of this center. Here again we find ourselves with no evidence that the content of our knowledge bears any relation to reality. We have merely the feeling of vividness attached to sensory experience which seems to bring us the certainty that there is some sort of a reality behind it, but this is not to give assurance that our ideal content even belongs rightfully to that against which we have bumped, much less of how it belongs—and only this deserves the title "knowledge."
In the chapter on "Quality and Comparison," in which he takes up the more detailed treatment of the simplest types of judgment of perception, he comes back to the same contradiction, and again attempts to explain how both horns of his dilemma must be true. The passage is this:
The Reality to which we ascribe the predicate is undoubtedly self-existent; it is not merely in my mind or in my act of judgment; if it were, the judgment would only be a game with my ideas. It is well to make this clear in the case before us, for in the later forms of the judgment it will be much disguised. Still the reality which attracts my concentrated attention is also within my act of judgment; it is not even the whole reality present to my perception; still less of course the whole self-existent Reality which I dimly presuppose. The immediate subject of the judgment is a mere aspect, too indefinite to be described by explicit ideas except in as far as the qualitative predication imposes a first specification upon it. This Reality is in my judgment; it is the point at which the actual world impinges upon my consciousness as real, and it is only by judging with reference to this point that I can refer the ideal content before my mind to the whole of reality which I at once believe to exist, and am attempting to construct. The Subject is both in and out of the Judgment, as Reality is both in and out of my consciousness. (Pp. 113, 114.)
The conclusion he reaches is a mere restatement of the difficulty. The problem he is trying to solve is how the subject can be both in and out of the judgment, and how the subject without is related to the subject within. The mere assertion that it is so does not help us to understand it. His procedure seems like taking advantage of two meanings of sense-perception, its conscious quality and its brute abrupt immediacy, and then utilizing this ambiguity to solve a problem which grows out of the conception of judgment as a reference of idea to reality.
Turning from his treatment of the world of fact to his discussion of the world of idea, from the subject to the predicate, as it appears in his theory of the judgment we find again a paradox which must be recognized and cannot be obviated. An idea is essentially a meaning. It is not a particular existence whose essence is uniqueness as is the case with the subject of the judgment, but is a meaning whose importance is that it may apply to an indefinite number of unique existences. Its characteristic is universality. And yet an idea regarded as a psychical existence, an idea as a content in my mind, is just as particular and unique as any other existence. How, then, does it obtain its characteristic of universality? Bosanquet's answer is that it must be universal by means of a reference to something other than itself. Its meaning resides, not in its existence as a psychical image, but in its reference to something beyond itself. Now, any idea that is affirmed is referred to reality, but do ideas exist which are not being affirmed? If so, their reference cannot be to reality. Bosanquet discusses the question in the second section of his introduction as follows:
It is not easy to deny that there is a world of ideas or of meanings, which simply consists in that identical reference of symbols by which mutual understanding between rational beings is made possible. A mere suggestion, a mere question, a mere negation, seem all of them to imply that we sometimes entertain ideas without affirming them of reality, and therefore without affirming their reference to be a reference to something real or their meaning to be fact. We may be puzzled indeed to say what an idea can mean, or to what it can refer, if it does not mean or refer to something real—to some element in the fabric continuously sustained
