B.5.RA:4.4a.3 - Recover the intermediate conclusions and missing grounds

Work backward from the proposed conclusion and forward from its offered reasons. Ask at each join what these reasons, if accepted, support immediately. A booking report may establish availability; availability together with a claim about the rehearsal’s requirements may establish feasibility; feasibility still needs a choice rationale before it supports selecting the venue. Write an intermediate conclusion when this distinction changes what can be challenged or reused. It has both roles: the result of one inference and a premise of another.

To find a hidden premise, explain why the stated reason bears on its target. Look for the condition, comparison, generalization or value judgement that would license that particular move. Ask whether the supplied reason could hold while the conclusion fails; the resulting counterexample can reveal an omitted qualification. For “the hall is available, so use it”, a hall too small for the cast exposes a requirement that availability alone cannot answer. An unfamiliar subject inference needs its subject method, not a sentence invented merely to make the arrow look complete.

Retain the different grounds for an addition. A context-supported implicit premise belongs to the recovered interpretation, with the supporting context made clear. An unresolved candidate premise remains a question about what the speaker meant. A premise you independently investigate or introduce belongs to your repaired argument. One bracket style is optional; these distinctions are not. Do not add a premise equivalent to “these premises establish this conclusion” as an explanation of why they do.

Try the resulting account against the original passage. Can it explain the role of each relevant contribution and the conclusion’s stated strength? Does it attribute something the source could consistently deny? Does an apparently unused sentence support an intermediate claim, supply an objection, or merely explain the occasion? Revise the arrangement when these questions expose a better reading. Leaving a passage as background can be faithful; making every sentence support the final conclusion cannot be a goal.
