Language, that is to say, is the indispensable mechanism of human life -- of life such as ours that is molded, guided, enriched, and made possible by… - S. I. Hayakawa

A human being, then, is never dependent on his own experience alone for his information. Even in a primitive culture he can make use of the experience of his neighbors, friends, and relatives, which they communicate to him by means of language. Therefore, instead of remaining helpless because of the limitations of his own experience and knowledge, instead of having to discover what others have already discovered, instead of explporing the false traits they explored and repeating their errors, he can go on from where they left off. Language, that is to say, makes progress possible.

However obvious these facts may appear at first glance, they are actually not so obvious as they seem except when we take special pains to think about the subject. Symbols and things symbolized are independent of each other; nevertheless, we all have a way of feeling as if <span style="color:green" title=", and sometimes acting as if,">[...] there were necessary connections. For example, there is a vague sense we all have that foreign languages are inherently absurd; foreigners have such funny names for things, and why can't they call things by their right names? This feeling exhibits itself most strongly in those tourists who seem to believe that they can make the natives of any country understand English if they shout loud enough. Like the little boy who was reported to have said, "Pigs are called pigs because they are such dirty animals," they feel that the symbol is inherently connected in some way with the thing symbolized. Then there are the people who feel that since snakes are "nasty, slimy creatures" (incidentally, snakes are not slimy), the word "snake" is a nasty, slimy word. </SPAN>

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.
