Compare four statements by locating negation:
1. “Zayd is learned” — affirmative non-metathetic: no negation.
2. “Zayd is not learned” — simple negative: the link is denied.
3. “Zayd is a non-scholar” — affirmative with a negated predicate term.
4. “Zayd is not a non-scholar” — negative with a negated predicate term.
The point is to distinguish quality of the proposition from the structure of the terms, rather than treating both as the same question.
