These persuasive modes can be used in any combination & order.
Effective persuasion, especially in a contentious issue, will usually blend all three.
However, we’d argue that the modes do have a loose cause-and-effect hierarchy:
- Character is essential because if the audience doesn’t trust the speaker, emotion & logic can backfire.
- Emotion is often needed to motivate the audience to take action.
- Logic is the one that seems like it should work all the time, but, in practice, it often fails if character and emotion haven’t been established.
