As words are not the things we speak about, and structure is the only link between them, structure becomes the only content of knowledge. If we gamble on verbal structures that have no observable empirical structures, such gambling can never give us any structural information about the world. Therefore such verbal structures are structurally obsolete, and if we believe in them, they induce delusions or other semantic disturbances.
Alfred KorzybskiHe who learns and learns and yet does not know what he knows, is one who plows and plows yet never sows.
Alfred KorzybskiIf we, who live outside asylums, act as if we lived in a fictitious world- that is to say, if we are consistent with our beliefs- we cannot adjust ourselves to actual conditions, and so fall into many avoidable semantic difficulties. But the so-called normal person practically never abides by his beliefs, and when his beliefs are building for him a fictitious world, he saves his neck by not abiding by them. A so-called "insane" person acts upon his beliefs, and so cannot adjust himself to a world which is quite different from his fancy.
