Some omissions invite the listener to participate in recovering the implied subject. The effect goes beyond shortness: the listener's attention is directed to a meaning inferred from the context. The text calls one possible purpose suggesting a move to the stronger of two indications.
أو تخييل العدول إلى أقوى الدليلين من العقل واللفظ
Or to create the impression of turning to the stronger of the two indications, reason and wording.
The commentarial discussion on pages 133–134 qualifies the claim. The word “suggesting” matters: this is an effect of expression, not proof that inference always outranks language. The omission still needs an identifiable cue and a fitting situation.
