In the following passage, both description and narra tion are used in the service of exposition, the exposition of a woman's personality:

"Mrs. Peacocke, in her line, succeeded almost as well [as her husband]. She was a woman something over thirty years of age when she first came to Bowick, in the very pride and bloom of woman's beauty. Her complexion was dark and brown,- so much so, that it was impossible to describe her colour generally by any other word. But no clearer skin was ever given to a woman. Her eyes were brown, and her eye-brows black, and perfectly regular. Her hair was dark and very glossy, and always dressed as simply as the nature of a woman's head will allow. Her features were regular, but with a great show of strength. She was tall for a woman, but without any of that look of length under which female altitude sometimes suffers. She was strong and well made, and apparently equal to any labour to which her position might subject her. When she had been at Bowick about three months, a boy's leg had been broken, and she had nursed him, not only with assiduity, but with great capacity. The boy was the youngest son of the Marchioness of Altamont; and when Lady Altamont paid a second visit to Bowick, for the sake of taking her boy home as soon as he was fit to be moved, her ladyship made a little mistake. With the sweetest and most caressing smile in the world, she offered Mrs. Peacocke a tenpound note. 'My dear madam,' said Mrs. Peacocke, without the slightest reserve or difficulty, 'it is so natural that you should do this, because you cannot of course understand my position; but it is altogether out of the question.' The Marchioness blushed, and stammered, and begged a hundred pardons. Being a good-natured woman, she told the whole story to Mrs. Wortle. 'I would just as soon have offered the money to the Marchioness herself,' said Mrs. Wortle, as she told it to her husband. 'I would have done it a deal sooner,' said the Doctor. I am not in the least afraid of Lady Altamont; but I stand in awful dread of Mrs. Peacocke.' Nevertheless Mrs. Peacocke had done her work by the little lord's bed-side, just as though she had been a paid nurse.

"And so she felt herself to be. Nor was she in the least ashamed of her position in that respect. If there was aught of

shame about her, as some people said, it certainly did not come from the fact that she was in receipt of a salary for the performance of certain prescribed duties. Such remuneration was, she thought, as honourable as the Doctor's income; but to her American intelligence, the acceptance of a present of money from a Marchioness would have been a degradation."

Examples of exposition.

Among examples of successful exposition that are too long to quote are: the lecture on "Idealism and Naturalism," in Mr. Otto Pfleiderer's "Philosophy and Development of Religion;" the chapter on "Intellectual Education," in Mr. Herbert Spencer's "Education;" the chapter on "Money," in Mill's "Principles of Political Economy;" the chapter on "Sweetness and Light," in Matthew Arnold's "Culture and Anarchy;" the report of the Committee on Secondary School Studies to the National Council of Education; Walter Bagehot's "English Constitution;" Mr. A. R. Wallace's "Darwinism." 2

CHAPTER IV.

ARGUMENT.

from

ARGUMENT, like exposition, addresses the understanding; but there is an important difference between the two. Exposition achieves its purpose if it makes the Argument persons addressed understand what is said; distinguished argument achieves its purpose if it makes exposition. them believe that what is maintained is true: exposition aims at explaining, argument at convincing. The difference between an argument and an exposition may be shown by a comparison between the address of an advocate to the jury and the charge of the judge. The advocate tries to convince the jury that his client has the right on his side; the judge, if he has the truly judicial spirit, tries to make the jury understand the question at issue exactly as it is.

sition may be more effective than it would be in its own form.

Argument prepared for

The way for argument is often prepared by exposition. Some words of the assertion in dispute may need to be defined and their relations to one another made by exposition. clear. If the subject is novel or complex, the assertion as a whole may need to be explained before the argument is begun. It is useless to try to convince a man of the truth of anything that he does not understand.

PROPOSITION AND PROOF.

defined. or disproved,

The body of every composition in which reasoning plays an important part consists of the PROPOSITION in dispute, the assertion which is to be proved and the PROOF, which includes whatever tends to show either that this proposition is true or that it is false. The aim of argument is to convince the persons addressed that the proof is sufficient to establish, or to overthrow, the proposition.

A word not a subject for argument.

[ocr errors]

For exposition a word may serve as subject, since one form of exposition is the definition of a word; but for argument a word cannot so serve. Honesty," for example, is in no just sense a subject for argument; for, though many propositions about honesty can be framed, the word by itself suggests no one of them rather than another: but "Honesty is the best policy" is a subject; for it makes a definite assertion, an assertion that can be reasoned about.

Nothing can free a writer or a speaker from the obliga tion of having the proposition distinctly fixed in his own

of having

mind before he begins his argument; for he cannot safely take the first step toward proving a proposition until he knows exactly what proposition is Importance to be proved. The process of investigation, by a distinct proposition which a man arrives at certain conclusions, in mind. should be completed before the argumentative process, by which he endeavors to convince others of the correctness of those conclusions, can advantageously be begun.

Proof may be either direct or indirect. Direct proof goes straight to the desired conclusion. Indirect proof demonstrates the truth of a proposition by Proof, direct showing that the opposite conclusion is absurd; and indirect. it is, therefore, called reductio ad absurdum.

A familiar example of reductio ad absurdum may be taken from a treatise on geometry:

"Two perpendiculars to the same straight line are parallel.

[blocks in formation]

"Let the lines A B and C D be perpendicular to A C.

"To prove A B and C D parallel.

"If A B and C D are not parallel, they will meet in some point if sufficiently produced.

“We should then have two perpendiculars from the same point to A C, which is impossible.

[From a given point without a straight line but one perpen dicular can be drawn to the line.]

"Therefore, A B and C D cannot meet, and are parallel. " 1
