1. Lesson on 'Understanding the Art of Argumentation and Proof' #4

2. Preparation for 'Understanding the Argumentative Method of Proof' - Version 5
I. Basic Knowledge
Question 1. Provide an example and explain: In life, when do people need to prove something? When you need to prove to someone that your statement is true, what should you do? From that, what can we conclude about the nature of proof?
Answer:
In life, we often clarify something for others or make them believe our assertions. People will only trust someone's statement if it is based on solid grounds, grounded in facts that are widely accepted. For example, to prove you're ill, you would need a doctor's certificate. Thus, to prove something is to use what is accepted as true or real to show that a claim is credible.
Question 2. In argumentative texts, when one can only use words (without witnesses or evidence), how do we prove that a particular point is true and reliable?
Answer:
In argumentative writing, proof is achieved by employing reasoning, using logical arguments to assert that a point is valid (instead of presenting physical evidence). These arguments must be carefully selected and clearly presented to have the greatest persuasive power.
Question 3. Read the following argumentative text and answer the questions.
DON'T FEAR FAILURE
How many times have you fallen without even remembering? The first time you tried walking, you fell. The first time you tried swimming, you swallowed water and nearly drowned, right? The first time you played table tennis, did you hit the ball? It doesn't matter because...
Walt Disney was once fired by a newspaper for lacking creativity. He also went bankrupt several times before creating Disneyland.
Louis Pasteur, when he was in high school, was only an average student. In Chemistry, he ranked 15th out of 22 students in his class.
Leo Tolstoy, the author of the famous novel *War and Peace*, was expelled from university because he was deemed both incapable and lacking in effort.
Henry Ford went bankrupt five times before succeeding.
The famous opera singer Enrico Caruso was told by his teacher that he lacked the necessary vocal talent and would never be able to sing.
So, don't worry about failure. What’s truly frightening is missing out on many opportunities simply because you didn't try your best.
(According to *The Heart Has Miraculous Powers*)
Questions:
a. What is the main argument of this text? Identify the sentences that express this argument.
b. How does the text argue “Don’t fear failure”? Are the facts presented trustworthy? What does this teach you about the method of argumentative proof?
Answer:
a. The central argument is: Don’t fear failure.
- “How many times have you fallen without remembering?”
- “So, don’t worry about failure. What’s truly frightening is missing out on many opportunities simply because you didn’t try your best.”
b. The argument method of the text:
- Failure is a normal part of life (uses examples).
- It provides evidence of famous people’s failures.
- What’s worse than failure is not trying at all.
The facts presented are trustworthy. From this, we understand that argumentative proof is about using sound reasoning and real examples to validate a claim.
II. Practicing Skills
Read the following essay and answer the questions.
DON’T FEAR MISTAKES
If you want to live a life without ever making a mistake and doing everything perfectly, you’re either deluding yourself or you're too afraid to face reality.
A person who is always afraid of failure, who fears making mistakes, is someone who is afraid to face life, avoiding reality, and will never become independent. If you’re afraid of choking on water, you’ll never learn to swim. If you’re afraid of speaking wrongly, you’ll never speak a foreign language! A person who refuses to risk anything will never gain anything. Mistakes have two sides. Although they bring losses, they also teach valuable life lessons.
How can you avoid making mistakes in the future? If you’re afraid of making mistakes, you won’t dare to do anything. If others say you’re wrong, it doesn’t necessarily mean you are, because the standards of right and wrong can vary. In that case, don’t stop; keep going, even if you face setbacks. Failure is the mother of success.
Of course, you shouldn’t be reckless or intentionally make mistakes. No one likes mistakes. Some people get discouraged when they fail, while others keep making the same mistakes. But there are those who reflect, learn from their mistakes, and find new paths forward.
The wise are those who dare to act and are not afraid of mistakes; they are the ones who control their own fate.
(According to Hong Diem)
Questions:
a. What is the main argument of the text? Identify the sentences that express this argument.
b. To prove the main argument, what reasoning does the writer use? Are these arguments convincing?
c. How is the method of argumentative proof in this text different from the one in *Don’t Fear Failure*?
Answer:
a. The main argument of the text is: Don’t fear mistakes.
- “If you want to live a life without ever making a mistake and doing everything perfectly, you’re either deluding yourself or you're too afraid to face reality.”
- “Mistakes have two sides. Although they bring losses, they also teach valuable life lessons.”
- “Failure is the mother of success.”
- “The wise are those who dare to act and are not afraid of mistakes; they are the ones who control their own fate.”
b. The writer uses the following reasoning to support the argument:
- If you fear failure, you won’t achieve anything: A person who is always afraid of making mistakes will never become independent. If you’re afraid of choking on water, you won’t learn to swim; if you’re afraid of speaking wrongly, you’ll never speak a foreign language.
- Mistakes are unavoidable on the path to the future: If you’re afraid of mistakes, you won’t try anything. Failure is necessary for success.
- Don’t make mistakes recklessly, but learn from them: You should reflect on your mistakes, learn from them, and find new ways to progress.
These arguments are convincing as they emphasize the importance of learning from mistakes and not letting fear hold you back.
c. In *Don’t Fear Failure*, the writer uses examples of famous people to support the argument, while in *Don’t Fear Mistakes*, the writer uses logical reasoning and analysis to explain the benefits of overcoming mistakes.

I. Purpose and Methods of Proof
Question 1:
In life, we often clarify things for others or convince them to believe our observations. People can only trust a statement if it is backed by solid evidence, based on facts that are widely accepted. For example, to prove you are sick, you would need to present a doctor's note.
Thus, proving means using what is acknowledged as true and factual to demonstrate that something is trustworthy.
Question 2:
In argumentative writing, proof is the use of reasoning and logic to affirm that a claim is true, even without providing physical evidence. Reasoning and examples must be carefully selected, clearly presented, and rich in detail to be persuasive.
Question 3:
a. The main argument of the essay is: Don’t fear failure.
b. The following sentences express this central idea:
+ How many times have you stumbled and forgotten about it?
+ So, don’t fear failure. What’s more frightening is missing opportunities because you didn’t try hard enough.
b. The author provides very credible examples:
- Examples of everyday failures are provided.
- The author mentions five world-famous individuals who faced failures but didn’t let them stop them from achieving great success later on.
Thus, proof is a form of reasoning where facts and logical arguments are used to show that the claim being made is valid and trustworthy.
II. Practice
a. The title 'Don’t Fear Mistakes' is the main argument of the essay.
- Sentences that reflect the main argument of the essay include:
- If you want to live a life without mistakes, achieving anything easily, you’re either dreaming or you’re too afraid of life.
- Mistakes have two sides. While they bring loss, they also bring lessons for life.
- Failure is the mother of success.
- Only those who dare to act and aren’t afraid of mistakes control their own fate.
b. To prove the main argument, the writer uses several supporting points:
- If you don’t take risks, you won’t gain anything: A person who is constantly afraid of failure or mistakes will never be independent. If you’re afraid of choking, you’ll never learn how to swim; if you’re afraid of making mistakes, you’ll never learn a foreign language!
- Mistakes are inevitable when moving toward the future: If you’re afraid of mistakes, you won’t dare to do anything. Someone might say you’re wrong, but that doesn’t mean you are. Different people have different definitions of right and wrong. Don’t stop; keep going, even when you face difficulties. Failure is the mother of success.
- Don’t be reckless, blind, or willfully make mistakes, but instead learn from them: Of course, you shouldn’t be reckless or intentionally make mistakes. Nobody enjoys mistakes. Some people give up after failing, others continue making the same mistakes. But those who reflect, learn from their mistakes, and find another way forward are the ones who succeed.
c. In 'Don’t Fear Stumbling,' the writer uses reasoning and witnesses, while in 'Don’t Fear Mistakes,' the writer uses reasoning and analysis of that reasoning.

Section I: Purpose and Methods of Proof
Answer to Question 1 (page 41, Literature 7, Volume 2):
Provide examples and explain: When do people need to prove something in life? When you need to convince someone that your words are true, how should you proceed? From that, what can we conclude about what 'proof' means?
Detailed Answer:
In life, people need proof when they want to use facts to confirm whether something is true or false. If you need to prove to someone that your statement is true, you must present the facts, include witnesses, and provide evidence or reasoning to clarify the matter. For example, saying “Student A is the best in class” must be supported by evidence like top grades in all subjects, consistently achieving high marks, and being recognized for their work by teachers.
Proof involves using facts (verifiable evidence) to show that something is trustworthy.
Answer to Question 2 (page 41, Literature 7, Volume 2):
In argumentative writing, when one is only allowed to use words (without witnesses or physical evidence), how can one prove that an opinion is true and credible?
Detailed Answer:
In argumentative writing, when only words can be used (without witnesses or physical evidence), reasoning and examples must be presented to prove that a statement is valid and credible.
Answer to Question 3 (page 41, Literature 7, Volume 2):
Read the text (pages 41-42, Literature 7, Volume 2) and answer the questions:
a) What is the central argument of this essay? Identify the sentences that support this argument.
b) How does the essay argue for 'don’t fear failure'? Are the facts presented reliable? Through this, what do you understand by the method of proof in argumentation?

Sentences supporting this argument include:
- How many times have you stumbled and forgotten about it?
- So, don’t worry about failure.
b) To encourage people 'not to fear failure,' the essay argues as follows:
* Introduction:
+ First introduces the concept of proof.
+ Then presents indisputable, objective evidence: For example, “Did you hit the ball on your first try at table tennis?” is a fact: likely, you missed!
* Main Body:
+ Cites five examples of famous individuals who faced failure but went on to achieve greatness:
- Walt Disney went bankrupt multiple times before creating Disneyland.
- Louis Pasteur was a mediocre student, especially in chemistry, yet his breakthrough in science led to his fame.
- Leo Tolstoy, once rejected for his lack of academic ability and willpower, later became a great writer.
- Henry Ford failed five times before succeeding with the Ford Motor Company.
- Singer Caruso was once told he lacked talent but went on to become famous.
* Conclusion:

6. Lesson Plan on 'Understanding the Proof Argument Method' - Exercise 3
I. Purpose and Methods of Proof
Question 1: In everyday life, when we want to assert something, we need to provide proof.
To convince others, we must present reliable evidence.
From this, we can conclude: Proof is presenting valid evidence to affirm something is true.
Question 2: In written texts, people can’t use witnesses or material evidence as in court. Instead, they use words to present reasoning and to cite reliable evidence. Writers also analyze this evidence to establish its authenticity and create persuasion.
Question 3: Read the essay 'Don’t Fear Failure'. Answer the following questions:
a) The central argument of the essay is “Don’t fear failure.”
The sentences that express this argument include the essay's title and its conclusion: “Therefore, don’t fear failure. What’s scarier is missing opportunities simply because you didn’t try your best.”
b) To encourage people to “don’t fear failure,” the essay uses the following approach:
It begins by questioning your past failures and asserts that failure is not something to fear. Then it provides examples of individuals who faced setbacks but eventually succeeded in fields like business, science, literature, and the arts.
Conclusion: Failure itself is not scary—what’s truly frightening is not striving to overcome challenges in life.
- The facts presented are highly credible, as they are drawn from the biographies of well-known, successful individuals.
From this, we understand that the method of proof in argumentation involves using logical reasoning combined with solid evidence to prove the credibility of a claim.
Remember:
In life, we use facts (reliable evidence) to show that something is true.
In argumentative writing, proof is an argumentative method that uses logical reasoning and verifiable evidence to show that a claim is trustworthy.
The reasoning and evidence used in proof must be carefully selected, validated, and analyzed to be persuasive.
II. Practice
Read the essay 'Don’t Fear Mistakes.' Answer the questions:
a) The argument of the essay: Don’t fear mistakes. Even if you make mistakes, learn from them, and find another way to move forward.
The sentences supporting this argument are:
- The essay title.
- A person who is afraid of making mistakes... will never become self-reliant.
- Failure is the mother of success.
- Those who are wise, who dare to act and are not afraid of mistakes, are the true masters of their fate.
b) To support their argument, the author provides the following reasoning:
- If you want to live a life without making mistakes, it’s an illusion or cowardice before life.
- If failure or mistakes prevent progress, no one would ever achieve anything. Mistakes provide valuable life lessons.
- If you fear mistakes, you will never dare to do anything.
- No one enjoys making mistakes, but when you do, you must learn from them to move forward.
These reasons are very much in line with real-life experiences, making them highly persuasive.
c) The argumentative method in this essay differs from that in 'Don’t Fear Failure.'
- The introduction presents a different view: it asserts that making mistakes is inevitable in life.
- In the body of the essay: In 'Don’t Fear Failure,' the author uses numerous real-life examples from successful individuals’ biographies as evidence.
In this essay, the author primarily relies on reasoning and analysis to prove their point. The reasoning covers multiple aspects, such as how fearing mistakes is avoiding reality, how mistakes have two sides: one causing loss and the other providing valuable lessons, and how one should confidently proceed with their tasks despite failure. Failure is portrayed as the precursor to success.
