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.)
