• propositional reps can be analog.

"A proposition is an assertion about the relation between informational entities." [281]

"In addition, it is not often recognized that propositions are capable of encoding an analog image. Higher-level propositions can be decomposed into lower-level propositions until they are reduced to primitive propositions about points. A Triangle, for example, can be decomposed into propositions about its component angles; these angles can then be decomposed into propositions abouttheir component lines; and the lines can be further decomposed into propositions about their component points... At its lowest level, a propositional encoding becomes sessentially equvalent to an analog representation." [282] Components of a visual system: [297]

• lexicon of 2d shapes from which higher-order structural descriptions can be generated to encode a retinal image.
