How To Read A Book- A Classic Guide to Intelligent Reading - Mortimer J. Adler, Charles Van Doren [48]
both steps are indispensable. If language is used without thought, nothing is being communicated. And thought or knowledge cannot be communicated without language. As arts, grammar and logic are concerned with language in relation to thought and thought in relation to language. That is why skill in both reading and writing is gained through these arts.
This business of language and thought-especially the distinction between words and terms-is so important that we are going to risk being repetitious to be sure the main point is understood. The main point is that one word can be the vehicle for many terms, and one term can be expressed by many words. Let us illustrate this schematically in the following manner. The word "reading" has been used in many senses in the course of our discussion. Let us take three of these senses: By the word "reading" we may mean ( 1 ) reading to be entertained, ( 2 ) reading to get information, and ( 3 ) reading to achieve understanding.
Now let us symbolize the word "reading" by the letter X, and the three meanings by the letters a, b, and c. What is symbolized in this scheme by Xa, Xb, and Xc, are not three words, for X remains the same throughout. But they are three terms, on the condition, of course, that you, as reader, and we, as writers know when X is being used in one sense and not another. If we write Xa in a given place, and you read Xb, we are writing and you are reading the same word, but not in the same way. The ambiguity prevents or at least impedes communication. Only when you think the word as we think it, do we have one thought between us. Our minds cannot meet in X, but only in Xa or Xb or Xc. Thus we come to terms.
Finding the Key Words
We are now prepared to put flesh on the rule that requires the reader to come to terms. How does he go about doing it?
How does he find the important or key words in a book?
Coming to Terms With an Author 1 01
You can be sure of one thing. Not all the words an author uses are important. Better than that, you can be sure that most of his words are not. Only those words that he uses in a special way are important for him, and for us as readers. This is not an absolute matter, of course, but one of degree. Words may be more or less important. Our only concern is with the fact that some words in a book are more important than others. At one extreme are the words that the author uses as the proverbial man in the street does. Since the author is using these words as everyone does in ordinary discourse, the reader should have no trouble with them. He is familiar with their ambiguity and he has grown accustomed to the variation in their meanings as they occur in this context or that.
For example, the word "reading" occurs in A. S. Eddington's book, The Nature of the Physical World. He speaks of
"pointer-readings," the readings of dials and gauges on scientific instruments. He is using the word "reading" in one of its ordinary senses. It is not for him a technical word. He can rely on ordinary usage to convey what he means to the reader.
Even if he used the word "reading" in a different sense somewhere else in the book-in a phrase, let us say, such as "reading nature" -he could be confident that the reader would note the shift to another of the word's ordinary meanings. The reader who could not do this could not talk to his friends or carry on his daily business.
But Eddington is not able to use the word "cause" so lightheartedly. That may be a word of common speech, but he is using it in a definitely special sense when he discusses the theory of causation. How that word is to be understood makes a difference that both he and the reader must bother about. For the same reason, the word "reading" is important in this book. We cannot get along with merely using it in an ordinary way.
An author uses most words as men ordinarily do in conversation, with a range of meanings, and trusting to the context to indicate the shifts. Knowing this fact is some
