The second persuasive lever is emotion, stirring the audience's feelings.
Some of the power of emotion is simply about grabbing and holding the audience's attention. Keeping them focused long enough to absorb the speaker's message.
But the main power of emotion is the power to move, both inwardly and outwardly. (The idea of 'motion' is baked into the word. The origin is Latin, e + movere, "an outward movement".)
- Emotion can drive new behaviour, sometimes pushing through the weight of inertia or routine.
- And strong feelings can colour everything an audience thinks or believes.
