A: “The book cover is as red as a flower” — single sensory: one visible property.
B: “The scholar resembles his teacher in learning and forbearance” — multiple intellectual: two independent traits.
C: “Scattered shining objects in a dark sky are like falling stars in night” — sensory composite: colour, position and motion form one whole.
D: “Possessing a means of knowledge yet failing to benefit from it” — intellectual composite: opportunity and non-use form one connected relation.
The subsequent discussion develops multiple points of resemblance in further detail, particularly independent sensory qualities and their possible combinations.
