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 dr… - S. I. Hayakawa

Of all forms of symbolism, language is the most highly developed, most subtle, and most complicated. It has been pointed out that human beings, by agreement, can make anything stand for anything. Now, human beings have agreed, in the course of centuries of mutual dependency, to let the various noises that they can produce <span style="color:green" title="with their lungs, throats, tongues, teeth, and lips systematically">[...] stand for specified happenings in their nervous systems. We call that system of agreements language. For example, we who speak English have been so trained that, when our nervous systems register the presence of a certain kind of animal, we may make the following noise: "That's a cat." Anyone hearing us expects to find that, by looking in the same direction, he will experience a similar event in his nervous system -- one that will lead him to make an almost identical noise. Again, we have been so trained that when we are conscious of wanting food, we make the noise "I'm hungry." </SPAN>

The process by means of which human beings can arbitrarily make certan things stand for other things may be called the symbolic process. Whenever two or more human beings can communicate with each other, they can, by agreement, make anything stand for anything. For example, here are two symbols: X Y We can agree to let X stand for buttons and Y for bows; then we can freely change our agreement and let X stand for [...] North Korea, and Y for South Korea. We are, as human beings, uniquely free to manufacture and manipulate and assign values to our symbols as we please. Indeed, we can go further by making symbols that stand for symbols. [...] This freedom to create symbols of any assigned value and to create symbols that stand for symbols is essential to what we call the symbolic process.

From the moment he switches on an early-morning news broadcast until he falls asleep at night over a novel or a magazine, he is, like all other people living in modern civilized conditions, swimming in words. Newspaper editors, politicians, salesmen, disc jockeys, columnists, luncheon club speakers, and clergymen; colleagues at work, friends, relatives, wife and children; market reports, direct-mail advertising, books, and billboards -- all are assailing him with words all day long. <span style="color:green" title="And Mr. Mits himself is constantly contributing to that verbal Niagara every time he puts on an advertising campaign, delivers a speech, writes a letter, or even chats with his friends.">[...] </SPAN>
