Rhetoric is the ancient art of persuasion. The Greek thinker Aristotle taught that we convince others in three ways: through character (ethos), emotion (pathos) and reason (logos).
Why this matters Persuasion is everywhere – charity appeals, adverts, community speeches and debates. Understanding the tools lets you argue for good causes convincingly and, just as importantly, spot when someone is trying to sway you unfairly.
The three appeals
- Ethos (character) – the speaker earns trust: “As someone who has volunteered at the food bank for three years…”
- Pathos (emotion) – the speaker stirs feeling: “Imagine a child who goes to bed hungry tonight.”
- Logos (logic) – the speaker offers reasons and evidence: “A weekly donation of one pound would feed forty families a month.”
Strong persuasion usually blends all three.
Rhetorical devices
These techniques make language memorable:
- Rule of three – three items for rhythm: “education, opportunity and hope.”
- Repetition – repeating a phrase for emphasis.
- Rhetorical question – a question that makes the listener think, not answer aloud.
- Direct address – speaking to ‘you’ to include the audience.
- Emotive language – words chosen to stir feeling.
Persuade honestly
Rhetoric can be misused to mislead. A good speaker keeps to the truth, backs claims with real evidence, and appeals to fairness rather than fear. Persuading people to volunteer, to be kind or to stand up for what is right is rhetoric used well. Ask yourself: would I be happy if the audience knew exactly how I was trying to persuade them? If yes, your rhetoric is honest.
Common exam mistake: Relying only on pathos — piling up emotive language with no evidence or credibility behind it. This can feel manipulative rather than persuasive. The strongest speeches blend feeling with genuine trust and solid reasoning, not emotion alone.
Exam technique: When analysing a persuasive speech, label each appeal as you find it — ethos, pathos or logos — in the margin. This trains you to see the structure beneath the words and gives you precise, technical vocabulary to use in your answer.
