Pathos, Ethos, Logos online exercise for - Free Printable

Let's solve the task step by step, starting with Task One, where we evaluate whether logos (appeal to logic) is being used effectively in each statement.

---

✔ Task One: Evaluate if Logos is Used Effectively

We need to determine whether each argument uses logical reasoning effectively. Remember:
- Logos = appeal to reason and logic.
- It must use facts, statistics, cause-effect relationships, or valid reasoning.
- Avoid emotional appeals (pathos) or false assumptions.

#### 1. "All men and women will die. You are a man. Therefore, you will die one day."
- ✔ Effective? Yes
- Explanation: This is a valid deductive argument using general premises to reach a logical conclusion. It follows the form of a syllogism:
- All humans die.
- You are human.
- Therefore, you will die.
→ This is logically sound and uses logos effectively.

---

#### 2. "Everyone has children. Therefore, everyone needs to think about the schooling of his or her children."
- ✘ Effective? No
- Explanation: The premise “everyone has children” is false — not everyone does. Even if it were true, the conclusion doesn’t follow logically for all people. For example, someone might have children but not be responsible for their schooling (e.g., due to adoption, custody, or disability). Also, “needs to think about” is subjective. The argument relies on a faulty generalization and lacks solid logic.

#### 3. "You don't need to jump in front of a train to know it's a bad idea; so why do you need to try drugs to know if they're damaging?"
- ✔ Effective? Yes
- Explanation: This uses an analogy to make a logical point. It compares two risky behaviors, arguing that just as you wouldn’t test danger by jumping in front of a train, you shouldn’t test drug damage by trying them. The comparison is reasonable and highlights the illogic of risking harm to gain knowledge. This is a strong use of logos through logical reasoning.

#### 4. "Cigarette smoke contains over 4,800 chemicals, 69 of which are known to cause cancer. So why start smoking?"
- ✔ Effective? Yes
- Explanation: This uses factual data (statistics about chemicals and carcinogens) to support a logical conclusion. The reasoning is clear: knowing the risks makes starting smoking irrational. It appeals to rational thought and evidence, making it a strong example of logos.

---

#### 5. "Every morning the rooster crows, then the sun rises. Therefore the rooster causes the sun to rise."
- ✘ Effective? No
- Explanation: This is a classic example of a false cause fallacy. Just because two events occur together (rooster crows → sun rises) doesn’t mean one causes the other. The correlation is mistaken for causation. This is not logical reasoning — it’s a misunderstanding of cause and effect. Thus, logos is not used effectively.

✔ Summary Table:

| # | Statement | Effective? | Explanation |
|---|---------|------------|-------------|
| 1 | "All men and women will die..." | Yes | Valid syllogism; logical deduction. |
| 2 | "Everyone has children..." | No | False premise; flawed generalization. |
| 3 | "Don't need to jump in front of train..." | Yes | Strong analogy; logical reasoning. |
| 4 | "Cigarette smoke contains 4,800 chemicals..." | Yes | Uses evidence and statistics logically. |
| 5 | "Rooster crows, sun rises..." | No | Correlation ≠ causation; fallacy. |

✔ Task Two: Write persuasive sentences using logos

Now, write persuasive statements using logical reasoning (facts, cause-effect, evidence).

---

#### 1. Persuade your brother to stop eating chocolate.

> "Chocolate contains high levels of sugar and saturated fat, which can increase the risk of heart disease and obesity over time. Studies show that reducing sugar intake improves long-term health. Since you want to stay healthy and active, cutting back on chocolate is a logical choice."

✔ Why it works: Uses health facts, references studies, links cause and effect.

---

#### 2. Convince your class not to drink and drive.

> "Alcohol impairs reaction time, judgment, and coordination — all critical skills for driving safely. According to the National Highway Traffic Safety Administration, drunk driving accounts for over 30% of traffic fatalities. If you drink and drive, you’re not just risking your life — you’re endangering others. The logical choice is to avoid drinking before driving."

✔ Why it works: Uses statistics, explains physiological effects, and emphasizes consequences.

---

#### 3. Persuade an audience to exercise more often.

> "Regular physical activity reduces the risk of chronic diseases like diabetes, heart disease, and depression. Research shows that even 30 minutes of moderate exercise five times a week can improve energy levels and mental health. By exercising regularly, you invest in your long-term well-being — a smart, logical decision for a healthier future."

✔ Why it works: Uses research, benefits, and long-term reasoning to build a rational case.

🎯 Final Notes:

- Logos means appealing to logic, not emotion.
- Always check: Is the reasoning valid? Are facts used correctly? Is there a fallacy?
- Strong logos includes evidence, clear cause-effect, and sound logic.
