A sensory point of resemblance (وجه الشبه الحسي) is grasped through an outward sense, such as redness, loudness or softness. A conceptual point (وجه الشبه العقلي) concerns an abstract quality or function, such as courage, generosity, knowledge or guidance.
“The face is red like a rose” compares sensory terms by a sensory quality. “Knowledge guides like light” compares a conceptual subject with sensory light, while the point—guidance or revealing the way—is itself conceptually understood, not a color.
It follows that the classification of the two terms and that of the shared point are distinct. An adequate answer may need to state both.
