- Bill's proposal covers this I think, about the input function of
- a category-level ICS accepting a disjunction of input signals
- corresponding to various perceptions, including a word or words.
- Thus, your imagined perception of RR on a white horse with a hat
- satisfies the category perception but without precluding other
- possibilities or even boggling much when encountering another
- instantiation. One could even go down the hall without a
- specific image in mind, but searching for any satisfier (other
- than the words "picatuare of RR on a horse"--aye, there's a rub).
