The Load-Bearing Metaphor
Build metaphors that carry the argument rather than decorate it.
The teaching
A decorative metaphor is a hat. A load-bearing metaphor is a beam.
Choose a source domain your listener has touched with their hands: tools, weather, roads, kitchens.
Then extend it once. Only once. A metaphor stretched three times snaps.
Example
'Preparation is the rehearsal room nobody claps for' carries more weight than 'preparation is important'.
- Concrete source domain beats an abstract one.
- Extend a metaphor once, never thrice.
- The metaphor should survive the removal of the sentence around it.
Drill
