Jeff, List: It looks like you may have inadvertently sent your reply to me only, rather than to the List. The whole thing is included below.
JD: Well, the subject terms in a proposition typically refer to existent objects or facts. In "Prolegomena," Peirce states, "A logical universe is, no doubt, a collection of logical subjects, but not necessarily of metaphysical Subjects, or ‘substances’; for it may be composed of characters, of elementary facts, etc." (CP 4.546, 1906). So at least in that context--assuming that "substances" are equivalent to "Things" and "characters" are equivalent to "Ideas"--"subjects" apparently need not be "existent objects or facts"; they can be items in *any *of the three Universes of Experience, which are apparently equivalent to "logical universes." JD: I was trying to direct your attention to a reading by Lieb of the letter to Lady Welby in 1908 where the 66-fold classificatory system of signs is made clearer. I am not sure of the reference here, since you did not mention Lieb in your initial post. Which reading?
