Considering whether the source and target are sensory or conceptual, and independently classifying the resemblance, yields several broad configurations. The type of resemblance does not automatically follow from the ontological status of the terms.
Examples include one visible brightness described by another, light standing for guidance, a conceptual emotion represented through observable action, and one mental state represented by another.
A sound analysis first identifies the two referents and then gives a separate reason for calling the shared respect sensory or conceptual.
