"Now, to use the famous metaphor by Alfred Korzybski in his Science and Sanity , this verbal world ought to stand in relation to the extensional world as a map does to the territory it is supposed to represent. If a child grows to adulthood with a verbal world in his head which corresponds fairly closely to the extensional world that he finds around him in his widening experience, he is in relatively small danger of being shocked or hurt by what he finds, because his verbal world has told him what, more or less, to expect. He is prepared for life. If, however, he grows up with a false map in his head he will constantly be running into trouble, wasting his efforts, and acting like a fool. He will not be adjusted to the world as it is: he may, if the lack of adjustment is serious, end up in a mental hospital."

“Mr. Mets is representative not only of the general public, but also of many scientific workers, publicists, and writers. Like most people, he takes words as much for granted as the air he breathes, gives them about as much thought. But Mr. Mets, like the rest of us, also adjusts himself automatically to changes in the verbal climate, from one type of discourse to another, from one set terms to another, from the listening habits of one kind of social occasion to those of another kind of social occasion, without conscious effort. He has yet, however, to acknowledge the effect of his verbal climate on his mental health and well-being.”

“Citizens of a modern society need more than that ordinary "common sense" which was defined by Stuart Chase as that which tells you that the world is flat. They need to be systematically aware of the powers and limitations of symbols, especially words, if they are to guard against being driven into complete bewilderment by the complexity of their semantic environment. The first of the principles governing symbols is this: The symbol is NOT the thing symbolized; the word is NOT the thing; the map is NOT the territory it stands for.”

“With words woven into almost every detail of his life, it seems amazing that Mr. Mets' thinking on the subject of language should be so limited.”

“One is reminded of the actor, playing the role of a villain in a traveling theatrical troupe, who, at a particularly tense moment in the play, was shot by an excited cowpuncher in the audience. But this kind of confusion does not seem to be confined to unsophisticated theatergoers. Paul Muni, after playing the part of Clarence Darrow in Inherit the Wind, was invited to address the American Bar Association; Ralph Bellamy, after playing the role of Frankin D. Roosevelt in Sunrise at Campobello, was invited by several colleges to speak on Roosevelt. Also, there are those astonishing patriots who rushed to the recruiting offices to help defend the nation when, on October 30, 1938, the United States was "invaded" by an "army from Mars" in a radio dramatization.”

“Whether he realizes it or not, however, Mr. Mets is affected every hour of his life not only by the words he hears and uses, but also by his unconscious assumptions about language. Such unconscious assumptions determine the effect that words have on him -- which in turn determines the way he acts, whether wisely or foolishly. Words -- the way he uses them and the way he takes them when spoken by others -- largely shape his beliefs, his prejudices, his ideals, his aspirations. They constitute the moral and intellectual atmosphere in which he lives -- in short, his semantic environment.”

“Indeed, most of the time when we are listening to the noises people make or looking at the black marks on paper that stand for such noises, we are drawing upon the experiences of others in order to make up for what we ourselves have missed. Obviously the more an individual can make use of the nervous systems of others to supplement his own, the easier it is for him to survive. And, of course, the more individuals there are in a group cooperating by making helpful noises at each other, the better it is for all -- within the limits, naturally, of the group's talents for social organization. Societies, both animal and human, might almost be regarded as huge cooperative nervous system.”
