سَأَلَ طَالِبٌ: أَكُلُّ قَدِيمٍ صَوَابٌ؟ فَقَالَ الْمُعَلِّمُ: لَيْسَ كُلُّ قَدِيمٍ صَوَابًا؛ الْحُجَّةُ هِيَ الْمِيزَانُ.
A student asked: “Is everything old correct?” The teacher replied: “Not everything old is correct; evidence is the criterion.”
The student asks a universal question. The teacher qualifies the universal claim and provides a positive standard for evaluation. The discourse progresses from question to correction to principle, rather than ending with negation.
A worked reading distinguishes interrogative function, quantifier scope, the pronoun’s potential focusing effect and the relationship between the teacher’s clauses. Necessary meaning and context-dependent intention should not be merged.
