Dragonfly's description has only two. Completing the analogy takes a third component, the representer, e.g. a homunculus. Dragonfly denies there being a homunculus in his account, but something that plays that role is what is needed to complete the analogy. Otherwise, it is poor analogy. I can agree to his use of "mapping" in one sense. One sense I would not accept is a parcel of land, a map, and the maker or viewer of the map. The map does represent the parcel, the maker or viewer is the representer, so the analogy holds. The acceptable sense is the way "mapping" is used in mathematics, but that is not a "representation."
