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.
