NLP holds that reality is unknown to us. Only how we subjectively experience reality is known to us.

In prison. – My eyes, however strong or weak they may be, can see only a certain distance, and it is within the space encompassed by this distance that I live and move, the line of this horizon constitutes my immediate fate, in great things and small, from which I cannot escape. Around every being there is described a similar concentric circle, which has a mid-point and is peculiar to him. Our ears enclose us within a comparable circle, and so does our sense of touch. Now, it is by these horizons, within which each of us encloses his senses as if behind prison walls, that we measure the world, we say that this is near and that far, this is big and that small, this is hard and that soft: this measuring we call sensation – and it is all of it an error! According to the average quantity of experiences and excitations possible to us at any particular point of time one measures one’s life as being short or long, poor or rich, full or empty: and according to the average human life one measures that of all other creatures – all of it an error! If our eyes were a hundredfold sharper, man would appear to us tremendously tall; it is possible, indeed, to imagine organs by virtue of which he would be felt as immeasurable. On the other hand, organs could be so constituted that whole solar systems were viewed contracted and packed together like a single cell: and to beings of an opposite constitution a cell of the human body could present itself, in motion, construction and harmony, as a solar system. The habits of our senses have woven us into lies and deception of sensation: these again are the basis of all our judgments and ‘knowledge’ – there is absolutely no escape, no backway or bypath into the real world! We sit within our net, we spiders, and whatever we may catch in it, we can catch nothing at all except that which allows itself to be caught in precisely our net.
