Lesson Five
I. Special terms in logic argument--a statement which is offered as an
evidence or a proof. It consists of two major elements
1. conclusion 2. premises -- a previous statement serving
as a basis for an argument. Conclusion is to be drawn from premises.
Special terms in logic
fallacy -- false reasoning, as in an argument a weakness and lack of logic or good
sense in an argument or piece of reasoning
fallacy
Usually, an argument is correct
(deductively valid) if the premises can
provide enough conclusive evidence for
the conclusion. Otherwise the argument is
wrong. It is said to be fallacious.
Special terms in logic
Three kinds of fallacy: 1. material fallacy -- in its material content
through a misstatement of the facts. 2. verbal fallacy -- in its wording through an
incorrect use of terms. 3. formal fallacy-in its structure through the
use of an improper process of inference.
False Analogy
"High school should not require a freshman writing course . Harvard doesn't require a freshman writing course, and the students get along fine without it".
--- The analogy is false because the two items don't have strong enough similarities to predict that what happens in one will happen in the other.
Dicta Simpliciter
"Everyone wants to get married someday."
--- The example starts a logical train of thought with an assumption that is false. Not "everyone" wants to get married.
Evading the issue
There are a number of handy fallacies th
at people press into service to side step
a problem while appearing to pursue the
point. ( 文不对题 )
1 ) Distraction
"Suds ' n ' Puds is a great restaurant : you can see how shining clean the kitchens are ".
--- The example is called distraction because the reader's attention is drawn to the cleanliness of the kitchen instead of to the excellence of the food, which is usually the determiner of a great restaurant.
2 ) Ad hominem
"against the person". "poisoning the well" " Ms Bauer is a terrible English teacher. She
always wears blue jeans" --- Instead of point out faults in teaching
technique, it calls attention to things about a teacher as a person that are unrelated to her teaching performance.
3 ) Ad misericordian (an appeal to pity)
"Look at this fourteen-year-old child who's run away from home to hide her shame-- pregnant, unwashed, friendless. penniless, at the mercy of our social service agencies. Can you till claim that sex should be taught in the classroom?"
3 ) Ad misericordian (an appeal to pity)
--- In this shifty approach to argumentation,
the writer gives tear jerking descriptions of
the cruel opponents' victims in order to
arouse sympathy from the reader.
Hasty Generalization
"Mr Wang's handwriting is terrible. Mr. Hu's handwriting is also terrible and you know how terrible men's handwriting is ."
--- It applies a special case to general rule. That fact that certain person's handwriting is bad doesn't imply that all men‘s handwriting is bad.
Post hoc, ergo propter hoc –
“After this, therefore because of this" "The last five times that I've worn my white
pants, something depressing has happened. I'm not going to wear those pants again!"
-- This fallacy assumes that if event Y happened after event X, then X must be the cause of Y.
Circular Reasoning
or Begging the question:
"Juan is an impressive speaker because he
always touches his listeners deeply."
Circular Reasoning
--- This problem occurs when the writer tries to support a claim by restating it in different words. You can tell this example is circular by considering this “Why is Juan an impressive speaker?” “Because he touches his listeners deeply.?” “Why are Juan's listeners touched so deeply?” “Because he is an impressive speaker.” impressive = touching someone deeply
Appeal to the Wrong Authority
"My political science teacher says that
the new math is impossible for children to
learn“.
Appeal to the Wrong Authority
--- If the student believes that political science teacher's low opinion of new math strongly supports an argument against new math, the student is wrong. The political science teacher is an authority, but in a different field.
Non Sequitur -- "it doesn't follow"
"Students who take earth science instead of physics are lazy. Susie took earth science instead of physics. Susie should be kicked out of school"
--- If the first statement is correct, then you could conclude that Susie is lazy. But there's nothing in that line of reasoning that says lazy students should be kicked out of school. The conclusion doesn't follow.
II. Detailed study of the text:
title -- humorous/ well chosen 1. When "fallacy" is taken in its ordinary
sense, the title means: There is a deceptive or delusive quality
about love. Love has delusive qualities
Detailed study of the text:
2. When "fallacy" is having logical sense, it means :
Love cannot be deduced from a set of given premises.
Love can not follow the given rules. Love is an error, a deception and an
emotion that does not follow the principles of logic.
Charles Lamb (1775-1834)
English essayist and critic who is now best known for his "Essays of Elia" (1823,1833). He collaborated with his sister Mary in adapting Shakespeare's plays into stories for children.

let sth go freely / be completely out of control
limp -- drooping, lacking firmness flaccid -- soft, flabby spongy -- soft, porous, full of holes, not firm specific characteristics of his writing (essay).

industrial working class through his essay "Chartism" and his book “The Present and the Past”. He is best known for his epic history of “The French Revolution” 1837 and his lectures “On Heroes and Hero-Workshop” 1841
Thomas Carlyle ( 1795-188)
He produced Sartor Resartus 1833-34, the boo
k in which he first developed his characteristic
style and thought. This book is a veiled Sardoni
c (scornful 挖苦的 ) attack upon the shams and
pretences of society, upon hollow rank, hollow
officialism, hollow custom, out of which life an
d usefulness have departed.
Thomas Carlyle ( 1795-188)
Carlyle developed a peculiar style of his own which was called --- "Carlyese" "Carlylism"

John Ruskin -- (1819-1900)
Positive program for social reforms: Sesame and Lilies (芝麻和百合) The Crown of Wild Olive The King of the Golden River
Implication:
My writing is even more informal. I can do
better than them. He says this only with his
tongue in cheek.
What is his purpose of writing this essay?
He compared logic to a living thing ( a
human being). Logic is not at all a dry
learned branch of learning. It is like a living
human being, full of beauty, passion and
painful emotional shocks.
Author’s note
1) His own idea about his own essay.
From his point of view, his essay is sth limp, spo
ngy. It is very informal.
2) His own idea about the purpose of that essay.
It is not a dry branch of learning , but like a hum
an being.

IV. The chief attraction of this lesson
It's humor The whole story is a piece of light, humorous
satire, satirizing a smug, self-conceited freshman in a law school.
IV. the chief attraction of this lesson
Why : 1) the title
The title is humorous. The writer wants the readers to conclude that "love" is an error, a deception and an emotion that does not follow the principles of logic.
IV. the chief attraction of this lesson
2) the author's note "spongy", "limp", "flaccid" are specific charact
eristics of his essay. He is joking, which indicates that the whole story is humorous.
3) the contrast -- the law student & the girl & Petey boasting himself ----- downgrading the others the student ---- the girl
IV. the chief attraction of this lesson
4) the ending of the story the raccoon coat which the law student des
pises and give it to his roommate for the exchange of his girl friend has finally become the rootcause of his losing his girl friend.

4. sharp contrast in the language 1) the law student uses ultra learned terms
standard English 100% correct
2) clipped vulgar forms, slang words gee, magnif, terrif, pshaw,
5. inverted sentences
V. Language features:
What effect does the language have on the readers: 1. vivid 2. colorful 3. informal
Exercise
1. Fads enjoy very brief popularity, which fashions are likely to be longer-lasting. Also, "fad" has a pejorative connotation. A fad is a cheap sort of fashion, somewhat debased. To be described as fashionable is a compliment. However, to be swayed by fads is to show a weakness for sudden and brief trends.
Exercise
2. "Incredible" means unbelievable. It comes from the Latin "in" (not), and "credibitis"(credible). "Incredulous" means disbelieving or skeptical. It is not as strong as "incredible"
Exercise
3. "Eager” suggests strong interest or desire. "Passionate" is nearly the same but generally is used in a more intense way, to express a degree of emotion slightly greater than "eager".
4. "Feeling" and “Emotions" are often considered interchangeable, though "emotions" is often considered the stronger word.
Exercise
5. "Revealed" is the better word here, with its connotation of making known what has been kept secret. "Showed" is a more general word and, while acceptable, is not as precise.
Exercise
6. To be "inclined" is to be disposed to do something, to have a tendency. To be tempted is to be attracted to something in a strong way, though again these two words are very close in meaning, I would rate "tempted" as the stronger verb.
Exercise
7. "Exasperation" is extreme annoyance or irritation. "Disappointed" indicates a degree of frustration less extensive than "exasperation". Again the author has chosen the stronger of the alternatives.
Exercise
8. “Tolerant” here implies endurance of Polly‘s faults, an ability to endure her stupidity. “Indulgent” means lenient( 宽大的 ) , forgiving, and the inner pain and difficulty implied by "tolerant"
Exercise
9. “Merriment” is gay conviviality (欢乐) , and hilarity (欢闹) . It is a much stronger word than "amusement", which refers to being pleased or entertained. Amusement is not so strong an emotion as merriment.
10. “Languish” means to become weak or feeble, to become listless. “To suffer a lot” is a vague, broad term. “Languish” is a better word in this case.
Ex. III.
1. It's humorous, thanks to the word "fallacy", one commonly used in logic. The tale not only gives us a clue of the nature of our narrator's passion, but reflects on the fallacy of his own love for Polly and fallacy in his seemingly well-wrought plan.
Ex. III.
2. Para 4 is a good example of the author's attitude toward himself. The audacious (brave) pride is so great that we can quickly see it is a parody. The author realizes that at 18 he felt smarter than he really was -- he was blind to his own ignorance. He makes fun of himself throughout.
Ex. III.
3. Its purpose is to entertain in a light-hearted way. There is no pretence to teaching us anything, but simply to give us a few chuckles. This is hinted at in the author's note.
4. Polly‘s language is trendy( 时髦的 ), inane(空洞的) , vulgar (粗俗的) , and meaningless. It illustrates, until the end of the story. It shows the limits of her weak mind.
Ex. III.
5. The narrator has learned logic as a subject in school, when he tries to apply his knowledge to real life, he fails miserably. He sees what goes on in the classroom is divorced from real life. He tries to make Polly forget the fallacies he had taught her.
6. The topic sentence is "He was a torn man". This idea is developed by a series of details that describe Petey's confused state.
Ex. III.
7. Because he begged Polly's love, which was refused. He was going to get the same result as Frankenstein, who created a monster that destroyed him, not as Pygmalion, who was loved by the beautiful statue he had fashioned. The narrator's allusions come naturally, from his experience. He has probably read Pygmalion and Frankenstein for a college course, so the allusions do seem apt.
Ex. III.
8. When the narrator finally succeeds in teaching Polly, she learns logic too well and turns it against him after his declaration of love. In her decision to choose Petey she had used the logic the narrator taught her. Had he not given away his raccoon coat and taught her logic lessons he might have had Polly as his own. The irony is that he succeeded to well.
Ex. III.
