Thus, we see that one of the obvious origins of human disagreement lies in the use of noises for words.
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.
