The Art of Argument — Persuasive Communication
MYP Unit Framework
Key Concept: COMMUNICATION Related Concepts: Audience Imperatives, Purpose, Structure Global Context: Fairness and Development (How can persuasive communication be used to advocate for justice and change?) Statement of Inquiry: Effective argument combines logical structure with rhetorical skill to influence belief and action.
Inquiry Questions
| Type | Question |
|---|---|
| Factual | What are Aristotle's three appeals (ethos, pathos, logos)? What is the structure of a formal debate? |
| Conceptual | How do rhetorical devices create persuasion? Why is understanding your audience essential to effective argument? |
| Debatable | Is persuasion always manipulation? Can an argument be both logical AND emotional — or does emotion weaken logic? |
ATL Skills
- Thinking: Construct logical arguments; evaluate the strength of evidence and reasoning
- Communication: Write persuasive essays; participate in formal debates
- Research: Gather evidence from credible sources to support arguments
- Social: Listen actively and respond respectfully to opposing views
- Self-Management: Prepare arguments under time constraints; manage debate protocols
1. The Foundations of Persuasion
Aristotle's Three Appeals
Ethos (Character/Credibility): The speaker's authority, trustworthiness, and character. The audience must believe the speaker is credible.
How to build ethos: Demonstrate expertise, show respect for the audience, be honest about limitations, use appropriate language.
Pathos (Emotion): Appealing to the audience's emotions — fear, anger, pity, hope, love, pride.
How to use pathos: Vivid imagery, personal stories, emotionally charged language, rhetorical questions.
Logos (Logic/Reason): Using evidence, facts, statistics, and logical reasoning.
How to build logos: Use data from reliable sources, construct clear cause-and-effect arguments, avoid logical fallacies.
The Rhetorical Triangle
The three appeals work together. A successful argument balances all three. Too much ethos may seem arrogant; too much pathos may seem manipulative; too much logos may seem cold.
2. Structuring an Argument
Classical Structure
- Exordium (Introduction): Capture attention, establish ethos, state the topic
- Narratio (Background): Provide context and relevant facts
- Propositio (Thesis): State your position clearly
- Confirmatio (Proof): Present evidence and reasoning supporting your position
- Refutatio (Refutation): Address and dismantle counterarguments
- Peroratio (Conclusion): Summarise key points, make a final emotional appeal, call to action
The T.E.E.L. Paragraph Structure
- Topic sentence: State the point of the paragraph
- Evidence: Provide a quote, fact, or example
- Explanation: Explain how the evidence supports your argument
- Link: Connect back to the thesis or to the next paragraph
The Counterargument
Addressing opposing views strengthens your argument. It shows you have considered alternative perspectives and demonstrates confidence in your position.
Structure: 'Some may argue that... However, this view overlooks... Furthermore...'
3. Rhetorical Devices
Devices of Emphasis
- Anaphora: Repetition at the beginning of successive clauses. 'We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields...' (Winston Churchill)
- Epistrophe: Repetition at the end of successive clauses
- Tricolon: Three parallel elements. 'Government of the people, by the people, for the people' (Abraham Lincoln)
Devices of Argument
- Rhetorical Question: A question asked for effect, not answer. 'Is this the sort of world we want to leave our children?'
- Antithesis: Contrasting ideas in parallel structure. 'It was the best of times, it was the worst of times.'
- Concession: Acknowledging a point from the opposing side before countering it
Devices of Emotion
- Imagery: Vivid sensory language that creates an emotional response
- Anecdote: A short personal story that illustrates the argument
- Hyperbole: Exaggeration for effect
- Inclusive Language: 'We', 'us', 'our' — creates a sense of shared identity
4. Logical Fallacies — Errors in Reasoning
Common Fallacies
| Fallacy | Definition | Example |
|---|---|---|
| Ad Hominem | Attacking the person, not the argument | 'You can't trust his opinion on climate change — he drives a car.' |
| Straw Man | Misrepresenting the opposing argument to make it easier to attack | 'Opponents of the policy want to do nothing about the problem.' |
| False Dilemma | Presenting only two options when more exist | 'Either we cut spending or the economy collapses.' |
| Slippery Slope | Arguing that one step inevitably leads to an extreme outcome | 'If we allow this, soon everything will be permitted.' |
| Appeal to Authority | Using an authority figure in an unrelated field | 'A famous actor says this medicine works, so it must be true.' |
| Hasty Generalisation | Drawing a conclusion from insufficient evidence | 'I met two rude people from that city; everyone there is rude.' |
| Circular Reasoning | The conclusion is included in the premise | 'This policy is good because it is the right thing to do.' |
Why Fallacies Matter
Logical fallacies weaken arguments. Recognising fallacies helps you:
- Evaluate the strength of others' arguments
- Strengthen your own reasoning
- Avoid being manipulated by weak arguments
5. Debate Skills
Debate Format
A formal debate typically involves:
- Affirmative Team: Argues FOR the motion
- Negative Team: Argues AGAINST the motion
- Time Limits: Each speaker has a set time
- Judging: Based on argument quality, evidence, and delivery
Constructing a Debate Case
- Define key terms in the motion
- Establish your team's position
- Present 2-3 main arguments with evidence
- Prepare responses to anticipated counterarguments
- Prepare a strong summary for the closing
Delivery Skills
- Eye contact with the audience and judges
- Clear, moderate pace of speaking
- Varying tone for emphasis
- Confident posture and gestures
- Using notes, not reading a script
6. Persuasive Essay Writing
Planning Your Essay
- Analyse the prompt: What are you being asked to argue?
- Research: Find evidence from credible sources
- Thesis: Formulate a clear, arguable claim
- Outline: Organise your main points and evidence
- Draft: Write with attention to structure, rhetoric, and style
- Revise: Check for clarity, logic, and persuasive force
Language for Persuasion
- Strong, confident verbs ('demands', 'proves', 'demonstrates')
- Modality: Use high-modality language for strong claims ('must', 'will', 'certainly')
- Connectives to show reasoning ('therefore', 'consequently', 'however', 'furthermore')
