والحسي من وجه الشبه سواء كان بتمامه حسياً أو ببعضه طرفاه حسيان لا غير
A sensory point, whether entirely or partly sensory, requires both compared terms to be sensory.
The relevant sensible property must be capable of belonging to the things being compared. An abstract meaning does not literally possess external colour or tangible texture in the way a body does.
One can nevertheless imagine or interpret a sensory image for an intellectual concept, as discussed in the earlier treatment of imaginative resemblance. That rhetorical operation should not be confused with the strict technical classification of a directly sensory point.
