Complex Passages: Sub-Conclusions

Captions available

The idea

In extended arguments, a statement can be both a conclusion (of earlier premises) and a premise (for the final conclusion). These are sub-conclusions.

In practice

"Rates rose, so borrowing slowed; and since borrowing slowed, growth will dip." "Borrowing slowed" plays both roles.

Where people slip

Miss the sub-conclusion and the whole diagram collapses into mush.
