Both Zayd and a lion have bodies composed of organs, yet their courage is not thereby a composite sensory point. The terms are complex physical entities while the intended respect is a single intellectual quality.
Similarly, “Zayd is human like ʿAmr” need not be a sensory compound simply because both persons have limbs. If the intended respect is humanity, the relevant analysis is different from a pattern of scattered elements.
The Pleiades-and-cluster comparison does depend on several visible units forming one arrangement. The proper subject of classification is therefore the point of resemblance, not the material make-up of the compared objects.
