A single sensory point is one quality known through an appropriate external sense: redness through sight, quietness through hearing, fragrance through smell, sweetness through taste, and softness through touch.
A single intellectual point is one chosen respect understood intellectually, even if it has observable signs: courage, lack of benefit, guidance toward a goal, or effective proof.
The compared objects themselves need not belong to the same perceptual class as the point. Two visible people may be compared in courage, an intellectual point. How a term is perceived and how its shared respect is known are different questions.
