Preserve the text and known version, then distinguish evidence of purpose from conjecture and present needs. Interpretation, amendments and exceptions have different scopes. Useful outcomes do not establish general permission; authority and necessary means require separate checks.
Questions explored
Does a convenient purpose establish original intention?
No: distinguish relevant evidence, conjecture and present needs. Unknown intention can remain unknown.
Does a useful outcome grant permission for future cases?
Not by itself: an action outcome, a private exception and an adopted shared condition differ.
Must a rule be amended?
No: clarification can end with a retained condition and particular disagreement. Direct contact is not prescribed under threats.
Key distinctions
A dispute can concern one word rather than the entire shared arrangement. (Leaving the room in the imagined scene.)
Quintilian considers written words and intention within historical instruction in argument. (VII.6.1–12; not contemporary law.)
Clarifying a current condition differs from creating a new one. (Explaining a word versus permitting a new break in the reading room.)
Found text, adopted conditions and application outcomes are different events. (Possible outcomes of the imagined conversation.)
Limits of interpretation
- Scene and participants are imagined.
- Not national law or permission to violate a condition.
- Confidence does not establish authority to amend arrangements.
- Useful outcomes do not establish correct interpretation.
- Unknown origin does not establish absence of purpose.
- Direct contact is not prescribed under threats.
