Association of ideas is a law by which, when one of two related ideas is mentioned, the other is suggested. To illustrate, when Manila is mentioned, Admiral Dewey appears; when treason is spoken of, Arnold is in the mind. This law is of fundamental importance in arranging an essay; one thing should suggest the next. But valuable as it is, even indispensable, it may become the source of much mischief. For instance, a pupil has this for a topic, “Reading gives pleasure to many.” He writes as his second sentence, “By pleasure I mean the opposite of pain,” and goes on. “All things are understood by their opposites. If we did not know sickness, we could not enjoy our [104] health. Joy is understood through sorrow. I remember my first sorrow. My father had just given me a new knife,—my first knife,” and so on from one thing to another. And not so unnaturally either; each sentence has suggested the next, but not one is on the topic. The most anxious watch must be kept in the selection of material. Some will be admitted without any question; some will be excluded with a brusqueness almost brutal. There is a third class, however, that is allied with the subject, yet it is not so easy to determine whether it should be admitted or rejected. This class requires the closest questioning. It must contribute to the strength of the essay, not to its pages, or it has no place there.
Scale of Treatment. There is another condition which must be considered in the selection of material, the scale of treatment. If Macaulay had been asked by a daily paper to contribute a paragraph of five hundred words on Milton, he could not have introduced all the numerous topics which have their place in his essay of one hundred pages. He might have mentioned Milton’s poetry and his character, the two main divisions of the present essay; but Dante and Æschylus, Puritan and Royalist, would scarcely have received notice. The second consideration in selecting material is the purpose and length of the essay, and the consequent thoroughness with which the subject is to be treated.
The exhaustiveness with which an author treats any subject depends, first, on his knowledge. Any person could write a paragraph on Milton; Macaulay and Lowell wrote delightful essays on the topic; David Masson has written volumes about him. These would have been impossible except to a person who had been a special student of the subject. Second, the thoroughness [105] of the treatment depends on the knowledge of the readers. For persons acquainted with the record of the momentous events of Milton’s time, it would have been quite unnecessary, it might be considered even an insult to intelligence, to go into such details of history. The shortest statement suffices when the reader is already familiar with the subject and needs only to know the application in this case. Third, the scale of treatment depends on the purpose for which the essay is written. If a newspaper paragraph, it is one thing; if for a magazine, it is quite another; if it is to be the final word on the subject, it may reach to volumes.
An apt illustration of proportion in the scale of treatment has been given by Scott and Denny in their “Composition-Rhetoric.” They suggest that three maps of the United States, one very large, another half the size of the first, and a third very small, be hung side by side. If a comparison be made, it will be found that, whereas a great number of cities are represented on the largest map, only half as many appear on the middle-sized map. If the smallest map be examined, only the largest cities, the longest rivers, the greatest lakes, and the highest mountains can be found; all others must be omitted. On all three maps the same relation of parts is maintained. In proportion to the whole, New York State will hold the same position in all of them. The Mississippi River will flow from Minnesota to the Gulf of Mexico, and the Gulf will sweep in a curve from Texas to Florida. The scale is different, but the proportion does not change.
This principle applies in the construction of themes. In a paragraph only very important topics will receive any mention. In an essay these important topics retain [106] their proper place and relation, while many other points of subordinate rank will be introduced. If the treatment be lengthened to a book, a host of minor sub-topics will be considered, each adding something to the development of the theme, and each giving to its principal topic the relative importance which belongs to the main divisions of the essay. The scale of treatment will have much to do with the selection of material.
Using Macaulay’s “Milton” as an illustration, the analyses below will show how by increasing the size of the essay new subjects come into the field for notice. The first is but a paragraph and has the two main divisions of the essay. The second is an outline for an essay of two thousand words. In the third only one of the sub-topics is analyzed, as Macaulay has discussed it. It would take too much space to analyze minutely the whole essay.
MILTON.
- Milton’s poetry has given him his position among great men.
- His conduct was such as was to be expected from a man of a spirit so high and of an intellect so powerful.
In the following outline the same main headings are retained, and the sub-topics which explain them are introduced. The numbers indicate the paragraphs in Macaulay’s essay given to each topic.
