How To Read A Book- A Classic Guide to Intelligent Reading - Mortimer J. Adler, Charles Van Doren [81]
Common experience does not have to be shared by everyone in order to be common. Common is not the same as universal. The experience of being a child of parents, for example, is not shared by every human being, for some are orphans from birth. However, family life is nevertheless common experience, because most men and women, in the ordinary course of their lives, share it. Nor is sexual love a universal experience, although it is common, in the sense we are giving the word common. Some men and women never experience it, but the experience is shared by such a high proportion of humans that it cannot be called special. ( This does not mean that sexual activity cannot be studied in the laboratory, as in fact it has been. ) The experience of being taught is not universal, either, for some men and women never go to school. But it, too, is common.
The two kinds of experience are mainly relevant to diHerent kinds of books. Common experience is most relevant to the reading of fiction, on the one hand, and to the reading of Aids to Reading 1 71
philosophy, on the other. Judgments concerning the verisimilitude of a novel are almost wholly based on common experience; the book, we say, is either true or not true to our experience of life as it is led by most people, ourselves included.
The philosopher, like the poet, appeals to the common experience of mankind. He does no work in laboratories or research in the field. Hence to understand and test a philosopher's leading principles you do not need the extrinsic aid of special experience. He refers you to your own common sense and your daily observation of the world in which you live.
Special experience is mainly relevant to the reading of scientific works. To understand and judge the inductive arguments in a scientific book, you must be able to follow the evidence that the scientist reports as their basis. Sometimes the scientist's description of an experiment is so vivid and clear that you have no trouble. Sometimes illustrations and diagrams help to acquaint you with the phenomena described.
Both common and special experience are relevant to the reading of history books. This is because history partakes both of the fictional and the scientific. On the one hand, a narrative history is a story, having a plot and characters, episodes, complications of action, a climax, an aftermath. The common experience that is relevant to reading novels and plays is relevant here, too. But history is also like science, in the sense that at least some of the experience on which the historian bases his work is quite special. He may have read a document or many documents that the reader could not manage to see without great trouble. He may have done extensive research, either into the remains of past civilizations or in the form of interviews with living persons in faraway places.
How do you know whether you are making proper use of your experience to help you understand a book? The surest test is one we have already recommended as a test of understanding: ask yourself whether you can give a concrete example of a point that
