This lesson focuses on Building an Argument: structure claims, evidence and counterarguments convincingly.

Definition: Building an Argument

Structure claims, evidence and counterarguments convincingly.

Key ideas

Concede to conquer

Strong arguments acknowledge the other side. A counterargument — critics argue X, but… — shows fairness and lets you demolish objections on your own terms. Ignoring opposition looks weak; answering it looks commanding.

The rhetorical triangle

Every persuasive act balances speaker, audience and message. Ethos convinces the audience to trust you, pathos makes them feel, and logos makes them think. The most powerful persuasion blends all three: evidence alone rarely moves people, and emotion alone rarely convinces them.

Key term — logos: Persuasion through logic and evidence. Statistics, reasoning and clear structure appeal to the rational mind.

Worked example: Building an Argument

What is a counterargument?

Acknowledging and answering an opposing view to strengthen your own position.

Answer: Acknowledging and answering an opposing view to strengthen your own position.

Common mistakes
  • Pathos without logos Emotion moves audiences but evidence convinces them. Even the most stirring speech needs facts beneath the feeling.
  • Piling on rhetorical questions One well-placed rhetorical question is powerful; five in a row sound hectoring. Vary your devices.
