Where open fireplaces are not used, several plans of ventilation may be used, as they all operate on the same principle. Two openings should be in the room, one of them near the floor, through which the fresh air may enter, the other higher up, and connected with a shaft or chimney, which producing a draft, may serve to free the room from impure air. The size of these openings may be regulated according to the size of the room.
—Baldwin:Essential Lessons in Human Physiology.
It is a singular fact, also, that the queen is made, not born. If the entire population of Spain or Great Britain were the offspring of one mother, it might be found necessary to hit upon some device by which a royal baby could be manufactured out of an ordinary one, or else give up the fashion of royalty. All the bees in the hive have a common parentage, and the queen and the worker are the same in the egg and in the chick; the patent of royalty is in the cell and in the food; the cell being much larger, and the food a peculiar stimulating kind of jelly. In certain contingencies, such as the loss of the queen with no eggs in the royal cells, the workers take the larva of an ordinary bee, enlarge the cell by taking in the two adjoining ones, and nurse it and stuff it and coddle it, till at the end of sixteen days it comes out a queen. But ordinarily, in the natural course of events, the young queen is kept a prisoner in her cell till the old queen has left with the swarm. Not only kept, but guarded against the mother queen, who only wants an opportunity to murder every royal scion in the hive. Both the queens, the one a prisoner and the other at large, pipe defiance at each other at this time, a shrill, fine, trumpetlike note that any ear will at once recognize. This challenge, not being allowed to be accepted by either party, is followed, in a day or two, by the abdication of the old queen; she leads out the swarm, and her successor is liberated by her keepers, who, in her turn, abdicates in favor of the next younger. When the bees have decided that no more swarms can issue, the reigning queen is allowed to use her stiletto upon her unhatched sisters. Cases have been known where two queens issued at the same time, when a mortal combat ensued, encouraged by the workers, who formed a ring about them, but showed no preference, and recognized the victor as the lawful sovereign. For these and many other curious facts we are indebted to the blind Huber.
It is worthy of note that the position of the queen cells is always vertical, while that of the drones and workers is horizontal; majesty stands on its head, which fact may be a part of the secret.
The notion has always very generally prevailed that the queen of the bees is an absolute ruler, and issues her royal orders to willing subjects. Hence Napoleon the First sprinkled the symbolic bees over the imperial mantle that bore the arms of his dynasty; and in the country of the Pharaohs the bee was used as the emblem of a people sweetly submissive to the orders of its king. But the fact is, a swarm of bees is an absolute democracy, and kings and despots can find no warrant in their example. The power and authority are entirely vested in the great mass, the workers. They furnish all the brains and foresight of the colony, and administer its affairs. Their word is law, and both king and queen must obey. They regulate the swarming, and give the signal for the swarm to issue from the hive; they select and make ready the tree in the woods and conduct the queen to it.
The peculiar office and sacredness of the queen consists in the fact that she is the mother of the swarm, and the bees love and cherish her as a mother and not as a sovereign. She is the sole female bee in the hive, and the swarm clings to her because she is their life. Deprived of their queen, and of all brood from which to rear one, the swarm loses all heart and soon dies, though there be an abundance of honey.
The common bees will never use their sting upon the queen,—if she is to be disposed of they starve her to death; and the queen herself will sting nothing but royalty—nothing but a rival queen.
—John Burroughs:Birds and Bees.
+Theme LXXXVI.+—Write an expository theme.
Suggested subjects:— 1. Duties of the sheriff. 2. How a motor works. 3. How wheat is harvested. 4. Why the tide exists. 5. How our schoolhouse is ventilated. 6. What is meant by the theory of evolution. 7. The manufacture of ——. 8. How to make a ——.
(Consider the arrangement of your statements.)
+157. Use of an Outline.+—Before beginning to write an explanation we need to consider what we know about the subject and what our purpose is; we need to select facts that will make our explanations clear to our readers; and we need to decide what arrangement of these facts will best show their relation to each other. We shall find it of advantage, especially in lengthy explanations, to express our thoughts in the form of an outline. An outline helps us to see clearly whether our facts are well chosen, and it also helps us to see whether the arrangement is orderly or not. Clearness is above all the essential of exposition, and outlines aid clearness by giving unity and coherence.
Select three of the following subjects and make lists of facts that you know about them. From these select those which would be necessary in making a clear explanation of each. After making out these lists of facts, arrange them in what seems to you the best possible order for making the explanation clear to your classmates.
1. The value of a school library. 2. Sponges. 3. The manufacture of clocks. 4. Drawing. 5. Athletics in the high school. 6. Examinations. 7. Debating societies.
+Theme LXXXVII.+—Following the outline, write an exposition on one of the subjects chosen.
(Notice the transition from one paragraph to another. See Section 87.)
+158. Exposition of Terms—Definition.+—Explanation of the meaning of general terms is one form of exposition (Section 63). The first step in the exposition of a term is the giving of a definition. This may be accomplished by the use of a synonym (Section 64). We make a term intelligible to the reader by the use of a synonym with which he is familiar; and though such a definition is inexact, it gives a rough idea of the meaning of the term in question, and so serves a useful purpose. If, however, we wish exactness, we shall need to make use of the logical definition.
+159. The Logical Definition.+—The logical definition sets exact limits to the meaning of a term. An exact definition must include all the members of a class indicated by the term defined, and it must exclude everything that does not belong to that class. A logical definition is composed of two parts. It first names the class to which the term to be defined belongs, and then it names the characteristic that distinguishes that term from all other members of the same class. The class is termed thegenus, and the distinguishing characteristics of the different members of the class are termed thedifferentia. Notice the following division into genus and differentia.
TERM TO BE | CLASS | DISTINGUISHINGDEFINED |(Genus)| CHARACTERISTIC| |(Differentia)| |A parallelogram | is a quadrilateral | whose opposite sides| | are parallel| |Exposition | is that form of | which seeks to explain| discourse | the meaning of a term.| |
Each definition includes three elements: the term to be defined, the genus, and the differentia; but these are not necessarily arranged in the order named.
Select the three elements (the term to be defined, the genus, and the differentia) in each of the following:—
1. A polygon of three sides is called a triangle.
2. A square is an equilateral rectangle.
3. A rectangle whose sides are equal is a square.
4. Description is that form of discourse which aims to present a picture.
5. The characters composing written words are called letters.
6. The olfactory nerves are the first pair of cranial nerves.
7. Person is that modification of a noun or pronoun which denotes the speaker, the person spoken to, or the person or things spoken of.
8. The diptera, or true flies, are readily distinguishable from other insects by their having a single pair of wings instead of two pairs, the hind wings being transformed into small knob-headed pedicles called balancers or halters.
+160. Difficulty of Framing Exact Definitions.+—In order to frame a logical definition, exactness of thought is essential. Even when the thought is exact, it will be found difficult and often impossible to frame a satisfactory definition. Usually there is little difficulty in selecting the genus, still care should be taken to select one that includes the term to be defined. We might begin the definition of iron by saying, "Iron is a metal," since all iron is metal, but it would be incorrect to begin the definition of rodent by saying, "A rodent is a beaver," because the term beaver does not include all rodents. We must also take care to choose for the genus some term familiar to the reader, because the object of the definition is to make the meaning clear to him.
The chief difficulty of framing logical definitions arises in the selection of differentia. In many cases it is not easy to decide just what characteristics distinguish one member of a class from all other members of that class. We all know that iron is a metal, but most of us would find it difficult to add to the definition just those things which distinguish iron from other metals. We may say, "A flute is a musical instrument"; so much of the definition is easily given. The difficulty lies in distinguishing it from all other musical instruments.
A.Select proper differentia for the following:—
|TERM TO BE DEFINED | CLASS (Genus) | DISTINGUISHING| | CHARACTERISTIC| |(Differentia)| |1. Narration | is that form of discourse | ?| |2. A circle | is a portion of a plane | ?| |3. A dog | is an animal | ?| |4. A hawk | is a bird | ?| |5. Physiography | is the science | ?| |6. A sneak | is a person | ?| |7. A quadrilateral | is a plane figure | ?| |8. A barn | is a building | ?| |9. A bicycle | is a machine | ?| |10. A lady | is a woman | ?
B.Give logical definitions for at least four words in the list below.
1. Telephone.
2. Square.
3. Hammer.
4. Novel
5. Curiosity.
6. Door.
7. Camera.
8. Brick.
9. Microscope.
+161. Inexact Definitions.+—If the distinguishing characteristics are not properly selected, the definition though logical in form may be inexact, because the differentia do not exclude all but the term to be defined. If we say, "Exposition is that form of discourse which gives information," the definition is inexact because there are other forms of discourse that give information. Many definitions given in text-books are inexact. Care should be taken to distinguish them from those which are logically exact.
Which of the following are exact?
1. A sheep is a gregarious animal that produces wool.
2. A squash is a garden plant much liked by striped bugs.
3. A pronoun is a word used for a noun.
4. The diaphragm is a sheet of muscle and tendon, convex on its upper side, and attached by bands of striped muscle to the lower ribs at the side, to the sternum, and to the cartilage of the ribs which join it in front, and at the back by very strong bands to the lumbar vertebrae.
5. A man is a two-legged animal without feathers.
6. Argument is that form of discourse which has for its object the proof of the truth or falsity of a proposition.
7. The base of an isosceles triangle is that side which is equal to no other.
8. Zinc is a metal used under stoves.
9. The epidermis of a leaf is a delicate, transparent skin which covers the whole leaf.
+Theme LXXXVIII.+—Write an expository paragraph about one of the following:—
Suggested subjects:— 1. Household science and arts. 2. Architecture. 3. Aesthetics. 4. Poetry. 5. Fiction. 6. Half tones. 7. Steam fitting. 8. Swimming.
(Consider the definitions you have used.)
+162. Division.+—The second step in the exposition of a term is division. Definition establishes the limits of the term. Division separates into its parts that which is included by the term. By definition we distinguish triangles from squares, circles, and other plane figures. By division we may separate them into scalene, isosceles, and equilateral, or if we divide them according to a different principle into right and oblique triangles. In either case the division is complete and exact. By completeness is meant that every object denoted by the term explained is included in the division given, thus making the sum of these divisions equal to the whole. By exactness is meant that but a single principle has been used, and so no object denoted by the term explained will be included in more than one of the divisions made. There are no triangles which are neither right nor oblique, so the division is complete; and no triangle can be both right and oblique, so the division is exact. Such a complete and exact division is calledclassification.
Nearly every term may be divided according to more than one principle. We may divide the termbooksinto ancient and modern, or into religious and secular, or in any one of a dozen other ways. Which principle of division we shall choose will depend upon our purpose. If we wish to discussspongeswith reference to their shapes, our division will be different from what it would be if we were to discuss them with reference to their uses. When a principle of division has once been chosen it is essential that it be followed throughout. The use of two principles causes an overlapping of divisions, thus producing what is called cross division. Using the principle of use, a tailor may sort his bolts of cloth into cloth for overcoats, cloth for suits, and cloth for trousers; using the principle of weight, into heavy weight and light weight; or he may sort them with reference to color or price. In any case but a single principle is used. It would not do to divide them into cloth for suits, light weight goods, and brown cloth. Such a division would be neither complete nor exact; for some of the cloth would belong to none of the classes while other pieces might properly be placed in all three.
In the exact sciences complete exposition is the aim, and classification is necessary; but in other writing the purpose in hand is often better accomplished by omitting minor divisions. A writer of history might consider the political growth, the wars, and the religion of a nation and omit its domestic life and educational progress, especially if these did not greatly influence the result that he wishes to make plain. If we wished to explain the plan of the organization of a high school, it would be satisfactory to divide the pupils into freshmen, sophomores, juniors, and seniors, even though, in any particular school, there might be a few special and irregular pupils who belonged to none of these classes. An exposition of the use of hammers would omit many occasional and unimportant uses. Such a classification though exact is incomplete and is calledpartition.
A.Can you tell which of the following are classifications? Which are partitions? Which are defective?
1. The inhabitants of the United States are Americans, Indians, and negroes.
2. Lines are straight, curved, and crooked.
3. Literature is composed of prose, poetry, and fiction.
4. The political parties in the last campaign were Republican and Democrat.
5. The United States Government has control of states and territories
6. Plants are divided into two groups: (1) the phanerogams, or flowering plants, and (2) cryptogams, or flowerless plants.
7. All phanerogamous plants consist of (1) root and (2) shoot; the shoot consisting of (a) stem and (b) leaf. It is true that some exceptional plants, in maturity, lack leaves, or lack root. These exceptions are few.
8. We may divide the activities of the government into: keeping order, making law, protecting individual rights, providing public schools, providing and mending roads, caring for the destitute, carrying the mail, managing foreign relations, making war, and collecting taxes.
B. Notice the following paragraphs, State briefly the divisions made.
+1. Plan of the Book.+—What is government? Who is the government? We shall begin by considering the American answers to these questions.
What does The Government do? That will be our next inquiry. And with regard to the ordinary practical work of government, we shall see that government in the United States is not very different from government in the other civilized countries of the world.
Then we shall inquire how government officials are chosen in the United States, and how the work of government is parceled out among them. This part of the book will show what is meant by self-government and local self-government, and will show that our system differs from European systems chiefly in these very matters of self-government and local self-government.
Coming then to the details of our subject, we shall consider the names and duties of the principal officials in the United States; first, those of the township, county, and city, then those of the state, and then those of the federal government.
Finally, we shall examine certain operations in the American system, such as a trial in court, and nominations for office, and conclude with an outline of international relations, and a summary of the commonest laws of business and property.
—Clark:The Government.
2. +Zoölogy and its Divisions.+—What things we do know about the dog, however, and about its relatives, and what things others know can be classified into several groups; namely, things or facts about what a dog does or its behavior, things about the make-up of its body, things about its growth and development, things about the kind of dog it is and the kinds of relatives it has, and things about its relations to the outer world and its special fitness for life.
All that is known of these different kinds of facts about the dog constitutes our knowledge of the dog and its life. All that is known by scientific men and others of these different kinds of facts about all the 500,000 or more kinds of living animals, constitutes our knowledge of animals and is the sciencezoölogy. Names have been given to these different groups of facts about animals. The facts about the bodily make-up or structure of animals constitute that part of zoölogy called animalanatomyormorphology;the facts about the things animals do, or the functions of animals, compose animalphysiology;the facts about the development of animals from young to adult condition are the facts of animaldevelopment;the knowledge of the different kinds of animals and their relationships to each other is calledsystematiczoölogy or animalclassification;and finally the knowledge of the relations of animals to their external surroundings, including the inorganic world, plants and other animals, is called animalecology.
Any study of animals and their life, that is, of zoölogy, may include all or any of these parts of zoölogy.
—Kellogg:Elementary Zoölogy.
3. Are not these outlines of American destiny in the near-by future rational? In these papers an attempt has been made:—
First, to picture the physical situation and equipment of the American in the modern world.
Second, to outline the large and fundamental elements of American character, which are:—
(a) Conservatism—moderation, thoughtfulness, and poise.(b) Thoroughness—conscientious performance, to the minutest detail,of any work which we as individuals or people may have in hand.(c) Justice—that spirit which weighs with the scales of righteousnessour conduct toward each other and our conduct as a nation towardthe world.(d) Religion—the sense of dependence upon and responsibility to theHigher Power; the profound American belief that our destiny is inHis hands.(e) The minor elements of American character—such as the tendency toorganize, the element of humor, impatience with frauds, and themovement in American life toward the simple and sincere.
—Beveridge:Americans of To-day and To-morrow.
C.Consult the table of contents or opening chapters of any text-book and notice the main divisions.
D.Find in text-books five examples of classification or division.
E.Make one or more divisions of each of the following:—
1. The pupils in your school.2. Your neighbors.3. The books in the school library.4. The buildings you see on the way to school.5. The games you know how to play.6. Dogs.7. Results of competition.
+Theme LXXXIX.+—Write an introductory paragraph showing what divisions you, would make if called upon, to write about one of the following topics:—
1. Mathematics.
2. The school system of our city.
3. The churches of our town.
4. Methods of transportation.
5. Our manufacturing interests.
6. Games that girls like.
7. The inhabitants of the United States.
(Have you mentioned all important divisions of your subject? Have you included any minor and unimportant divisions? Consider other possible principles of division of your subject. Have you chosen the one best suited to your purpose?)
+163. Exposition of a Proposition.+—Two terms united into a sentence so that one is affirmed of the other become a proposition. Propositions, like terms, may be either specific or general. "Napoleon was ambitious" is a specific proposition; "Politicians are ambitious" is a general one.
When a proposition is presented to the mind, its meaning may not at once be clear. The obscurity may arise from the fact that some of the terms in the proposition are unfamiliar, or are obscure, or misleading. In this case the first step, and often the only step necessary, is the explanation of the terms in the proposition. The following selection taken from Dewey'sPsychologyillustrates the exposition of a proposition by explaining its terms:—
The habitual act thus occurs automatically and mechanically. When we say that it occurs automatically, we mean that it takes place, as it were, of itself, spontaneously, without the intervention of the will. By saying that it is mechanical, we mean that there exists no consciousness of the process involved, nor of the relation of the means, the various muscular adjustments, to the end, locomotion.
It is possible for our listeners or readers to understand each term in a proposition and yet not be able to understand the meaning of the proposition as a whole. When this is the case, we shall find it necessary to make use of methods of exposition discussed later.
Explain orally the following propositions by explaining any of the terms likely to be unfamiliar or misunderstood:
1. The purpose of muscular contraction is the production of motion.
2. Ping-pong is lawn tennis in miniature, with a few modifications.
3. An inevitable dualism bisects nature.
4. Never inflict corporal chastisement for intellectual faults.
5. Children should be led to make their own investigations and to draw their own inferences.
6. The black willow is an excellent tonic as well as a powerful antiseptic.
7. Give the Anglo-Saxon equivalent for "nocturnal."
8. A negative exponent signifies the reciprocal of what the expression would be if the exponent were positive.
+Theme XC.+—Write an explanation of one of the following:
1. Birds of a feather flock together.
2. Truths and roses have thorns about them.
3. Where there's a will, there's a way.
4. Who keeps company with a wolf will learn to howl.
5. He gives nothing but worthless gold, who gives from a sense of duty.
6. All things that are, Are with more spirit chased than enjoyed.
7. Be not simply good—be good for something.
8. He that hath light within his own clear breast, May sit i' the center, and enjoy bright day; But he that hides a dark soul and foul thoughts Benighted walks under the midday sun; Himself is his own dungeon.
(Select the sentence that seems most difficult to you, determine what it means, and then attempt to make an explanation that will show that you thoroughly understand its meaning.)
+164. Exposition by Repetition.+—In discussing paragraph development (Section 50) we have already learned that the meaning of a proposition may be made clearer by the repetition of the topic statement. This repetition may be used to supplement the definition of terms, or it may by itself make clear both the meaning of the terms and of the proposition. Each repetition of the proposition presents it to the reader in a new light or in a stronger light. Each time the idea is presented it seems more definite, more familiar, more clear. Such statements of a proposition take advantage of the fact that the reader is thinking, and we merely attempt to direct his thought in such a way that he will turn the proposition over and over in his mind until it is understood.
Notice how the following propositions are explained largely by means of repetitions, each of which adds a little to the original statement.
How to live?—that is the essential question for us. Not how to live in the mere material sense only, but in the widest sense. The general problem, which comprehends every special problem, is the right ruling of conduct in all directions under all circumstances. In what way to treat the body; in what way to treat the mind; in what way to manage our affairs; in what way to bring up a family; in what way to behave as a citizen; in what way to utilize all those sources of happiness which nature supplies—how to use all our faculties to the greatest advantage of ourselves and others—how to live completely? And this being the great thing needful for us to learn, is, by consequence, the great thing which education has to teach. To prepare us for complete living is the function which education has to discharge: and the only radical mode of judging of any educational course, is, to judge in what degree it discharges such functions.
—Herbert Spencer:Education.
The gray squirrel is remarkably graceful in all his movements. It seems as though some subtle curve was always produced by the line of the back and tail at every light bound of the athletic little creature. He never moves abruptly or jerks himself impatiently, as the red squirrel is continually doing. On the contrary, all his movements are measured and deliberate, but swift and sure. He never makes a bungling leap, and his course is marked by a number of sinuous curves almost equal to those of a snake. He is here one minute, and the next he has slipped away almost beyond the ability of our eyes to follow.
—F. Schuyler Matthews:American Nut Gatherers.
+Theme XCI.+—Write a paragraph explaining one of the propositions below by means of repetition.
1. Physical training should be made compulsory in the high school.
2. Some people who seem to be selfish are not really so.
3. The dangers of athletic contests are overestimated.
4. The Monroe Doctrine is a warning to European powers to keep their hands off territory in North and South America.
5. By the "treadmill of life" we mean the daily routine of duties.
6. The thirst for novelty is one of the most powerful incentives that take a man to distant countries.
7. There are unquestionably increasing opportunities for an honorable and useful career in the civil service of the United States.
(Have you used any method besides that of repetition? Does your paragraph really explain the proposition?)
+165. Exposition by Use of Examples.+—Exposition treats of general subjects, and the topic statement of a paragraph is, therefore, a general statement. In order to understand what such a general statement means, the reader may need to think of a concrete case. The writer may develop his paragraph by furnishing concrete cases. (See Section 44.) In many cases no further explanation is necessary.
The following paragraph illustrates this method of explanation:—
The lower portions of stream valleys which have sunk below sea level are calleddrowned valleys. The lower St. Lawrence is perhaps the greatest example of a drowned valley in the world, but many other rivers are in the same condition. The old channel of the Hudson River may be traced upon the sea bottom about 125 miles beyond its present mouth, and its valley is drowned as far up as Troy, 150 miles. The sea extends up the Delaware River to Trenton, and Chesapeake Bay with its many arms is the drowned valleys of the Susquehanna and its former tributaries. Many of the most famous harbors in the world, as San Francisco Bay, Puget Sound, the estuaries of the Thames and the Mersey, and the Scottish firths, are drowned valleys.
—Dryer:Lessons in Physical Geography.
+Theme XCII.+—Develop one of the following topic statements into an expository paragraph by use of examples:—
1. Weather depends to a great extent upon winds.
2. Progress in civilization has been materially aided by the use of nails.
3. Habit is formed by the repetition of the same act.
4. Men become criminals by a gradual process.
5. Men's lives are affected by small things.
6. Defeat often proves to be real success.
(Have you made your meaning clear? Does your example really illustrate the topic statement? Can you think of other illustrations?)
+166. Exposition by Comparison or Contrast.+—We can frequently make our explanations clear by comparing the subject under discussion with something that is already familiar to the reader. In such a case we shall need to show in what respect the subject we are explaining is similar to or differs from that with which it is compared. (Section 48.) Though customary it is not necessary to compare the term under discussion with some well-known term. In the example below the termsocialismis probably no more familiar than the termanarchism. Both are explained in the selection, and the explanations are made clearer by contrasting the one with the other.
Socialism, which is curiously confounded by the indiscriminating with Anarchism, is its exact opposite. Anarchy is the doctrine that there should be no government control; Socialism—that is, State Socialism—is the doctrine that government should control everything. State Socialism affirms that the state—that is, the government—should own all the tools and implements of industry, should direct all occupations, and should give to every man according to his need and require from every man according to his ability. State Socialism points to the evils of overproduction in some fields and insufficient production in others, under our competitive system, and proposes to remedy these evils by assigning to government the duty of determining what shall be produced and what each worker shall produce. If there are too many preachers and too few shoemakers, the preacher will be taken from the pulpit and assigned to the bench; if there are too many shoemakers and too few preachers, the shoemaker will be taken from the bench and assigned to the pulpit. Anarchy says, no government; Socialism says, all government; Anarchy leaves the will of the individual absolutely unfettered, Socialism leaves nothing to the individual will; Anarchism would have no social organism which is not dependent on the entirely voluntary assent of each individual member of the organism at every instant of its history; Socialism would have every individual of the social organism wholly subordinate in all his lifework to the authority of the whole body expressed through its properly constituted officers. It is true that there are some writers who endeavor to unite these two antagonistic doctrines by teaching that society should be organized wholly for industry, not at all for government. But how a coöperative industry can be carried on without a government which controls as well as counsels, no writer, so far as I have been able to discover, has ever even suggested.
—Lyman Abbott:Anarchism: Its Cause and Cure.
+Theme XCIII.+—Write an exposition that makes use of comparison:—
Suggested subjects:— 1. A bad habit is a tyrant. 2. Typewritten letters. 3. The muskrat's house. 4. Compare Shylock with Barabas in Marlowe'sJew of Malta. 5. Methods of reading. 6. All the world's a stage. 7. Compare life to a flower.
(Can you suggest any other comparisons which you might have used? Have you been careful in your selection of facts and arrangement?)
+167. Exposition by Obverse Statements.+—In explaining an idea it is necessary to distinguish it from any related or similar idea with which it may be confused in the minds of our readers. Clearness is added by the statement that one isnotthe other. To say that socialism is not anarchy is a good preparation for the explanation of what socialism really is. In the following selection Burke excludes different kinds of peace and by this exclusion emphasizes the kind of peace which he has in mind.
The proposition is peace. Not peace through the medium of war; not peace to be hunted through the labyrinth of intricate and endless negotiations; not peace to arise out of universal discord, fomented from principle, in all parts of the empire; not peace to depend on the juridical determination of perplexing questions, or the precise marking the shadowy boundaries of a complex government. It is simple peace; sought in its natural course, and in its ordinary haunts.—It is peace sought in the spirit of peace; and laid in principles purely pacific. I propose, by removing the ground of the difference, and by restoring theformer unsuspecting confidence of the colonies in the Mother Country, to give permanent satisfaction to your people; and (far from a scheme of ruling by discord) to reconcile them to each other in the same act, and by the bond of the very same interest which reconciles them to British government.
+168. Exposition by Giving Particulars or Details.+—One of the most natural methods of explaining is to give particulars or details. After a general statement has been made, our minds naturally look for details to make the meaning of that statement clearer. (See Sections 45-47.) This method is used very largely in generalized descriptions and narrations.
Notice the use of particulars or details in the following examples:—
Happy the boy who knows the secret of making a willow whistle! He must know the best kind of willow for the purpose, and the exact time of year when the bark will slip. The country boy seems to know these things by instinct. When the day for whistles arrives he puts away marbles and hunts the whetstone. His jackknife must be in good shape, for the making of a whistle is a delicate piece of handicraft. The knife has seen service in mumblepeg and as nut pick since whistle-making time last year. Surrounded by a crowd of spectators, some admiring, some skeptical, the boy selects his branch. There is an air of mystery about the proceeding. With a patient indulgent smile he rejects all offers of assistance. He does not attempt to explain why this or that branch will not do. When finally he raises his shining knife and cuts the branch on which his choice has fallen, all crowd round and watch. From the large end between two twigs he takes a section about six inches long. Its bark is light green and smooth. He trims one end neatly and passes his thumb thoughtfully over it to be sure it is finished to his taste. He then cuts the other end of the stick at an angle of about 45°, making a clean single cut. The sharp edge of this is now cut off to make a mouthpiece. This is a delicate operation, for the bark is apt to crush or split if the knife is dull, or the hand is unskillful. The boy holds it up, inspecting his own work critically. Sometimes he is dissatisfied and cuts again. If he makes a third cut and is still unsuccessful he tosses the spoiled piece away. It is too short now. A half dozen eager hands reach for the discarded stick, and the one who gets it fondles it lovingly. I once had such a treasure and cherished it until I learned the secret of the whistle-maker's art. He next places the knife edge about half an inch back from the end of the mouthpiece and cuts straight towards the center of the branch about one-fourth the way through. A three-cornered piece is now cut out, and the chip falls to the ground unheeded.
When this is finished the boy's eye runs along the stick with a calculating squint. The knife edge is placed at the middle, then moved a short distance towards the mouthpiece. With skillful hand he cuts through the bark in a perfect circle round the stick. While we watch in fascinated silence, he takes the knife by the blade and resting the unfinished whistle on his knees he strikes firmly but gently the part of the stick between the ring and the mouthpiece. Only the wooden part of the handle touches the bark. He goes over and over it until every spot on its surface has felt his light blow. Now he lays the knife aside, and grasping the stick with a firm hand below the ring in the bark, with the right hand he holds the pounded end. He tries it with a careful twist. It sticks. Back to his knees it goes and the tap, tap, begins again. When he twists it again it slips, and the bark comes off smoothly in one piece, while we breathe a sigh of relief. How white the stick is under the bark! It shines and looks slippery. Now the boy takes his knife again. He cuts towards the straight jog where the chip was taken out, paring the wood away, sloping up to within an inch of the end of the bark. Now he cuts a thin slice of the wood between the edge of the vertical cut and the mouthpiece.
The whistle is nearly finished. We have all seen him make them before and know what comes next. Our tongues seek over moist lips sympathetically, for we know the taste of peeled willow. He puts the end of the stick into his mouth and draws it in and out until it is thoroughly wet. Then he lifts the carefully guarded section of bark and slips it back into place, fitting the parts nicely together.
The willow whistle is finished. There remains but to try it. Will it go?Does he dare blow into it and risk our jeers if it is dumb?
With all the fine certainty of the Pied Piper the boy lifts the humble instrument to his lips. His eyes have a far-off look, his face changes; while we strain eyes and ears, he takes his own time. The silence is broken by a note, so soft, so tender, yet so weird and unlike other sounds! Our hands quiver, our hearts beat faster. It is as if the spirit of the willow tree had joined with the spirit of childhood in the natural song of earth.
It goes!

+Theme XCIV.+—Write an exposition on one of the following subjects, making use of particulars or details:—
1. How ice cream is made.2. The cultivation of rice.3. Greek architecture.4. How paper is made.5. A tornado.6. Description of a steam engine.7. The circulatory system of a frog.8. A western ranch.9. Street furniture.10. A street fair.
(Have you used particulars sufficient to make your meaning clear? Have you used any unnecessary particulars? Why is the arrangement of your topics easy in this theme?)
+169. Exposition by Cause and Effect.+—When our general statement is in the form of a cause or causes, the question naturally arises in our mind as to the effects resulting from those causes. In like manner, when the general statement takes the form of an effect, we want to know what the causes are that produce such an effect. From the very nature of exposition we may expect to find much of this kind of discourse relating to causes and effects. (See Section 49.)
Notice the following example:—
The effect of the polar whirls may be seen in the rapid rotation of water in a pan or bowl. The centrifugal force throws the water away from the center, where the surface becomes depressed, and piles it up around the sides, where the surface becomes elevated. The water being deeper at the sides than at the center, its pressure upon the bottom is proportionately greater. A similar effect is produced by the whirl of the air around the polar regions. It is thrown away from the polar regions and piled up around the circumference of the whirl. There is less air above the polar regions than above latitude 30°-40°, and the atmospheric pressure is correspondingly low at one place and high at the other. Thus the centrifugal force of the polar whirl makes the pressure low in spite of the low temperature. The position of the tropical belts of high pressure is a resultant of the high temperature of the equatorial regions on one side and the polar whirls on the other.
—Dryer:Lessons in Physical Geography.
+Theme XCV.+—Write an expository theme using cause or effect.
Suggested subjects:—
1. The causes of the French Revolution. 2. How ravines are formed. 3. Irrigation. 4. Effects of smoking. 5. Lack of exercise. 6. Volcanic eruptions.
(Did you find it necessary to make use of any other method of explanation?Did you make use of description in any place?)
1. Exposition is that form of discourse the purpose of which is to explain.
2. The essential characteristics of an exposition are—a.That it possess unity because it contains only those factsessential to its purpose.b.That the facts used be arranged in a coherent order.
3. Exposition is concerned with (a) general terms or (b) generalpropositions.
4. The steps in the exposition of a term are—a.Definition. This may be—(1) By synonym (inexact).(2) By use of the logical definition (exact).b.Division. This may be—(1) Complete (classification).(2) Incomplete (partition).The same principle of division should be followed throughout.
5. Exposition of a proposition may use any one of thefollowing methods—a.By repetition.b.By giving examples.c.By stating comparisons and contrasts.d.By making obverse statements.e.By relating particulars or details.f.By stating cause or effect.g.By any suitable combination of these methods.
+170. Difference between Argument and Exposition.+—Argument differs from exposition in its purpose. By exposition we endeavor to make clear the meaning of a proposition; by argument we attempt to prove its truth. If a person does not understand what we mean, we explain; if, after he does understand, he does not believe, we argue.
Often a simple explanation is sufficient to convince. As soon as the reader understands the real meaning of a proposition, he accepts our view of the case. A heated discussion may end with the statement, "Oh, if that is what you mean, I agree with you." In Section 70, we have learned that the first step in argument is explanation, by which we make clear the meaning of the proposition the truth of which we wish to establish. This explanation may include both the expounding of the terms in the proposition and the explanation of the proposition as a whole.
There is another difference between exposition and argument. We cannot argue about single terms, though we may explain them. We may explain what is meant by the termelective studies, orcivil service;but an argument requires a proposition such as, Pupils should be allowed to choose their own studies, or, Civil Service should be established. Even with such a topic as Expansion or Restricted Immigration, which seems to be a subject of argument, there is really an implied proposition under discussion; as, The United States should acquire control of territory outside of its present boundaries; or, It should be the policy of our government to restrict immigration. We may explain the meaning of single terms or of propositions, but in order to argue, we must have a proposition either expressed or implied.
+171. Proposition of Fact and Proposition of Theory.+—Some propositions state facts and some propositions state theories. Every argument therefore aims either to prove the occurrence of a fact or the truth of a theory. The first would attempt to show the actual or probable truth of a specific proposition; for example:—
Nero was guilty of burning Rome.Joan of Arc was burned at the stake.Barbara Frietchie actually existed.Sheridan never made the ride from Winchester.Homer was born at Chios.
The second would try to establish the probable truth of a general theory; for example:—
A college education is a profitable investment.Light is caused by a wave motion of ether.
+172. Statement of the Proposition.+—The subject about which we argue may be stated in any one of the three forms discussed in Section 74; that is, as a declarative sentence, a resolution, or a question. The statement does not necessarily appear first in the argument, but it must be clearly formulated in the mind of the writer before he attempts to argue. Before trying to convince others he must know exactly what he himself believes, and the attempt to state his belief in the form of a proposition will assist in making his own thought clear and definite.
If we are going to argue concerning elective studies, we should first of all be sure that we understand the meaning of the term ourselves. Then we must consider carefully what we believe about it, and state our proposition so that it shall express exactly this belief. On first thought we may believe the proposition that pupils should be allowed to choose their own studies. But is this proposition true of pupils in the grades as well as in the high schools? Or is it true only of the upper classes in the high school or only of college students? Can you state this proposition so that it will express your own belief on the subject?
A. Use the following terms in expressed propositions:—
1. Immigration. 2. Elevated railways. 3. American history. 4. Military training. 5. Single session. 6. Athletics.
B. Explain the following propositions:—
1. The United States should adopt a free-trade policy. 2. Is vivisection justifiable? 3. The author has greater influence than the orator. 4. The civil service system should be abolished. 5. The best is always cheapest.
C. Can you restate the following propositions so that the meaning of each will be made more definite?
1. Athletics should be abolished. (Shouldallathletic exercises beabolished?)
2. Latin is better than algebra. (Betterfor what purpose?Betterforwhom?)
3. Training in domestic arts and sciences should be provided for high school pupils. (Define domestic arts and sciences. Should they be taught toallhigh school pupils?)
4. Punctuality is more important than efficiency.
5. The commercial course is better than the classical course.
6. A city should control the transportation facilities within its limits.
+Theme XCVI.+—Write out an argument favoring one of the propositions as restated in Exercise C above.
(Before writing, make a brief as indicated in Section 77. Consider the arrangement of your argument.)
+173. Clear Thinking Essential to Argument.+—Having clearly in mind the proposition which we wish to prove, we next proceed to give arguments in its support. The very fact that we argue at all assumes that there are two sides to the question. If we hope to have another accept our view we must present good reasons. We cannot convince another that a proposition is true unless we can tell him why it is true; and certainly we cannot tell him why until we know definitely our own reasons for believing the statement. In order to present a good argument we must be clear logical thinkers ourselves; that is, we must be able to state definite reasons for our beliefs and to draw the correct conclusions.
+174. Inductive Reasoning.+—One of the best preparations for trying to convince others is for us to consider carefully our own reasons for believing as we do. Minds act in a similar manner, and what leads you and me to believe certain truths will be likely to cause others to believe them also. A brief consideration of how our belief in the truth of a proposition has been established will indicate the way in which we should present our material in order to cause others to believe the same proposition. If you ask yourself the question, What leads me to believe as I do? the answer will undoubtedly be effective in convincing others.
Are the following propositions true or false? Why do you believe or refuse to believe each?
1. Maple trees shed their leaves in winter.2. Dogs bark.3. Kettles are made of iron.4. Grasshoppers jump.5. Giraffes have long necks.6. Raccoons sleep in the daytime.7. The sun will rise to-morrow.8. Examinations are not fair tests of a pupil's knowledge.9. Honest people are respected.10. Water freezes at 32° Fahrenheit.11. Boys get higher standings in mathematics than girls do.
It is at once evident that we believe a proposition such as one of these, because we have known of many examples. If we reject any of the propositions it is because we know of exceptions (we have seen kettles not made of iron), or because we do not know of instances (we may never have seen a raccoon, and so not know what he does in the daytime). The greater the number of cases which have occurred without presenting an exception, the stronger our belief in the truth of the proposition (we expect the sun to rise because it has never failed).
The process by which, from many individual cases, we establish the truth of a proposition is called +inductive reasoning+.
+175. Establishing a General Theory.+—A general theory is established by showing that for all known particular cases it will offer an acceptable explanation. By investigation or experiment we note that a certain fact is true in one particular instance, and, after a large number of individual cases have been noted, and the same fact found to be true in each, we assume that such is true of all like cases, and a general law is established. This is the natural scientific method and is constantly being made use of in pursuing scientific studies. By experiment, it was found that one particular kind of acid turned blue litmus red. This, of course, was not sufficient proof to establish a general law, but when, upon further investigation, it was found to be true of all known acids, scientists felt justified in stating the general law that acids turn blue litmus red.
In establishing a new theory in science it is necessary to bring forward many facts which seem to establish it, and the argument will consist in pointing out these facts. Frequently the general principle is assumed to be true, and the argument then consists in showing that it will apply to and account for all the facts of a given kind. Theories which have been for a time believed have, as the world progressed in learning, been found unable to account for all of a given class of conditions. They have been replaced, therefore, by other theories, just as the Copernican theory of astronomy has displaced the Ptolemaic theory.
Our belief may be based upon the absence of facts proving the contrary as well as upon the presence of facts proving the proposition. If A has never told an untruth, that fact is an argument in favor of his truthfulness on the present occasion. A man who has never been dishonest may point to this as an argument in favor of placing him in a position of trust. Often the strongest evidence that we can offer in favor of a proposition is the absence of any fact that would support the negative conclusion.
The point of the whole matter is that from the observation of a large number of cases, we may establish theprobabletruth of a proposition, but emphasis needs to be laid upon the probability. We cannot be sure. Not all crows are black, though you may never have seen a white one. The sun may not rise to-morrow, though it has never failed up to this time. Still it is by this observation of many individual cases that the truth of the propositions that men do believe has been established. We realize that our inductions are often imperfect, but the general truths so established will be found to underlie every process of reasoning, and will be either directly or indirectly the basis upon which we build up all argument.
We may then redefine inductive reasoning as the process by which from many individual cases we establish theprobabletruth of a general proposition.
Notice in the following selections that the truth of the conclusion is shown by giving particular examples:—
1. It is curious enough thatwe always remember people by their worst points, and still more curious thatwe always suppose that we ourselves are remembered by our best. I once knew a hunchback who had a well-shaped hand, and was continually showing it. He never believed that anybody noticed his hump, but lived and died in the conviction that the whole town spoke of him no otherwise than as the man with the beautiful hand, whereas, in fact, they only looked at his hump, and never so much as noticed whether he had a hand at all. This young lady, so pretty and so clever, is simply the girl who had that awkward history with So-and-so; that man, who has some of the very greatest qualities, is nothing more than the one who behaved so badly on such an occasion. It is a terrible thing to think that we are all always at watch one upon the other, to catch the false step in order that we may have the grateful satisfaction of holding our neighbor for one who cannot walk straight. No regard is paid to the better qualities and acts, however numerous; all the attention is fixed upon the worst, however slight. If St. Peter were alive he would be known as the man who denied his Master; St. Paul would be the man who stoned Stephen; and St. Thomas would never be mentioned in any decent society without allusions to that unfortunate request for further evidence. Probably this may be the reason why we all have so much greater a contempt for and distrust of each other than would be warranted by a correct balance between the good and the evil that are in each.

2. In the first place, 227 withered leaves of various kinds, mostly of English plants, were pulled out of worm burrows in several places. Of these, 181 had been drawn into the burrows by or near their tips, so that the footstalk projected nearly upright from the mouth of the burrow; 20 had been drawn in by their bases, and in this case the tips projected from the burrows; and 26 had been seized near the middle, so that these had been drawn in transversely and were much crumpled. Therefore 80 per cent (always using the nearest whole number) had been drawn in by the tip, 9 per cent by the base or footstalk, and 11 per cent transversely or by the middle. This alone is almost sufficient to show thatchance does not determine the manner in which leaves are dragged into the burrows.

3.The catastrophe of every play is caused always by the folly or fault of a man; the redemption, if there be any, is by the wisdom and virtue of a woman, and, failing that, there is none. The catastrophe of King Lear is owing to his own want of judgment, his impatient vanity, his misunderstanding of his children; the virtue of his one true daughter would have saved him from all the injuries of the others, unless he had cast her away from him; as it is, she all but saves him. Of Othello, I need not trace the tale; nor the one weakness of his so mighty love; nor the inferiority of his perceptive intellect to that even of the second woman character in the play, the Emilia who dies in wild testimony against his error:—
"Oh, murderous coxcomb! what should such a foolDo with so good a wife?"
InRomeo and Juliet, the wise and brave stratagem of the wife is brought to ruinous issue by the reckless impatience of her husband. InThe Winter's Tale, and inCymbeline, the happiness and existence of two princely households, lost through long years, and imperiled to the death by the folly and obstinacy of the husbands, are redeemed at last by the queenly patience and wisdom of the wives. InMeasure for Measure, the foul injustice of the judge, and the foul cowardice of the brother, are opposed to the victorious truth and adamantine purity of a woman. InCoriolanus, the mother's counsel, acted upon in time, would have saved her son from all evil; his momentary forgetfulness of it is his ruin; her prayer, at last, granted, saves him—not, indeed, from death, but from the curse of living as the destroyer of his country.

4.
_Bas. _So may the outward shows be least themselves;The world is still deceived with ornament.In law, what plea so tainted and corruptBut, being season'd with a gracious voice,Obscures the show of evil? In religion,What damned error, but some sober browWill bless it and approve it with a text,Hiding the grossness with fair ornament?There is no vice so simple but assumesSome mark of virtue on his outward parts:How many cowards, whose hearts are all as falseAs stairs of sand, wear yet upon their chinsThe beards of Hercules and frowning Mars,Who, inward search'd, have livers white as milk;And these assume but valor's excrementTo render them redoubted! Look on beauty,And you shall see 'tis purchased by the weight;Which therein works a miracle in nature,Making them lightest that wear most of it:So are those crisped snaky golden locksWhich make such wanton gambols with the wind,Upon supposed fairness, often knownTo be the dowry of a second head,The skull that bred them in the sepulcher.Thus ornament is but the guiled shoreTo a most dangerous sea; the beauteous scarfVeiling an Indian beauty; in a word,The seeming truth which cunning times put onTo entrap the wisest. Therefore, thou gaudy gold,Hard food for Midas, I will none of thee;Nor none of thee, thou pale and common drudge'Tween man and man: but thou, though meager lead,Which rather threatenest than dost promise aught,Thy paleness moves me more than eloquence;And here choose I: joy be the consequence!
—Shakespeare:The Merchant of Venice.
+Theme XCVII.+—Write a paragraph proving the truth of one of the following statements:—
1. It is a distinct advantage to a large town to be connected with the smaller towns by electric car lines.
2. Vertical penmanship should be taught in all elementary schools.
3. Examinations develop dishonesty.
4. Novel reading is a waste of time.
5. Tramps ought not to be fed.
(Make a brief. Consider the arrangement of your arguments. Read Section 72.)
+176. Errors of Induction.+—A common error is that of too hasty generalization. We conclude that something is always so because it happened to be so in the few cases that have come under our observation. A broader experience frequently shows that the hastily made generalization will not hold.
Some people are led to lose faith in all humanity because one or two of their acquaintances have shown themselves unworthy of their trust. Others are ready to pronounce a merchant dishonest because some article purchased at his store has not proved to be so good as it was expected to be. There are those who are superstitious concerning the wearing of opals, claiming that these jewels bring the wearer ill luck, because they have heard of some instances where misfortune seemed to follow the wearing of that particular stone. What may seem to be causes and effects at first may, upon further investigation or inquiry, prove to be merely chance coincidences. In your work in argument, whether for the class room or outside, be careful about this point. Remember that your induction will be weak or even worthless if you draw conclusions from too few examples.
Often one example seems sufficient to cause belief. We might believe that all giraffes have long necks, even though we had seen but one; but such a belief would exist because, by many examples of other animals, we have learned that a single specimen will fairly represent all other specimens of the same class. On the other hand, if this one giraffe should possess one brown eye and one white eye, we should not expect all other giraffes to have such eyes, for our observation of many hundreds of animals teaches us that the eyes of an animal are usually alike in color. In order to establish a true generalization, theessentialcharacteristics must be selected, and these cannot be determined by rule, but rather by common sense.
+177. Deductive Reasoning.+—When once a general principle has been established, we may demonstrate the truth of a specific proposition by showing that the general principle applies to it. We see a gold ring and say, "This ring is valuable," because we believe the general proposition, "All articles made of gold are valuable." Expressed in full, the process of reasoning would be—
A.All articles made of gold are valuable.B.This ring is made of gold.C.Therefore this ring is valuable.
A series of statements such as the above is called a syllogism. It consists of a major premise (A), a minor premise (B), and a conclusion (C).
