Gary R., Gary F., lists,

Yes, I think that the subindex is the singular symbol. Well, I can't say, for example, that Peirce didn't have in mind more than one kind of singular symbol, but I found no textual evidence for that. Anyway the singular symbol is a sign for an individual thing, and is singular in the same sense as a name like 'Socrates' is said in standard logic to be a singular term - not because the symbol or term itself is a singular object, but instead because it refers to a singular object. It really seems like the subindex, which, Peirce said, is not an individual. The simplest explanation is that the subindex is the singular symbol. I remember years ago looking very hard for a passage where comes out and says so, but I didn't find one.

Personal names, demonstratives, designations, etc., things that Peirce had customarily classified as indices but then classified instead as subindices in MS 478 (third section of "syllabus" - "Sundry Logical Conceptions"), are once again classified as indices in his writings after MS 478. So he quite seems to have dropped the non-index subindex.

I said that I wasn't sure that he stuck with the idea of the singular symbol. If he flatly identified it as the subindex, then I'd say that he dropped it. I don't know what he did with the abstract symbol, which I take to include abstract terms like 'redness'. Peirce was very likely aware of a traditional division of terms in logic into singular and general and into concrete and abstract, and he gets into the concrete/abstract thing in his ten sign-trichotomies.

So, putting your posts together, Ben, I think that you're saying that the *Singular Symbol* is better understood as the "Subindex" (you earlier remarked that Peirce didn't stick with the Singular Symbol notion)? Or are they equivalent terms?

And what do you make of the "Abstract Symbol" in the same sentence in which the "Singular Symbol" occurs?

Here are the Subindices quote followed by the Singular/Abstract Symbol quote again for ready reference for whomever may be interested in this analysis.

    Subindices or Hyposemes are signs which are rendered such
    principally by an actual connection with their objects. Thus a
    proper name, personal demonstrative, or relative pronoun or the
    letter attached to a diagram, denotes what it does owing to a real
    connection with its object but none of these is an Index, since it
    is not an individual. CP 2.284

    There are two kinds of degenerate symbols, the Singular Symbol
    whose Object is an existent individual, and which signifies only
    such characters as that individual may realize; and the Abstract
    Symbol, whose only Object is a character. CP 2.293

Best,

Gary

I'm not sure that Peirce stuck with his idea of a Singular Symbol. CP 2.293-4 is from the "Syllabus" (circa 1902, according to the CP editors). In a "Syllabus" passage - the one on subindices a.k.a. hyposemes, dated 1903, he said that indices are individuals - he had not embraced the idea of the indexical legisign yet.

    [Quote]
    _/Subindices/_ or _/hyposemes/_ are signs which are rendered such
    principally by an actual connection with their objects. Thus a
    proper name, [a] personal demonstrative, or relative pronoun or

I dimly remember another passage touching on this issue in "Syllabus" but it's been years and years.

Gary F, lists,

Gary wrote that in rereading the Speculative Grammar part of the Syllabus that this struck him:

    GF: that the interpretant of a dicisign or proposition
    represents the sign itself as well as its object, and represents
    it as an /index/ — which, strictly speaking, lacks the
    /generality/ which makes the argument a symbol and thus more
    genuine.

I think that your rewording /is/ helpful (but then see the CP 2.293-4 quoted below which tends to complicate the matter for me); and, further, that your notion that the reason that Peirce did so much self-rewording was "to get through to the real, general, genuine Thought that was . . . a piece of the Truth" and not a more (mere) personal expression of it, makes good sense. I'm not sure that his re-wordings /always/ made his thinking more transparent, but often enough they did.

You also asked why I thought that Peirce's comment that "A proof or genuine argument is a mental process which is open to logical criticism"

    GR: . . . is in any way incompatible with the notion that the
    dicisign might be described as 'degenerate' relative to the
    argument.

First, would you say that a 'proof' is but a species of genuine argument? While it makes a kind of sense to me to say that the dicisign is degenerate relative to the argument, I wonder if this isn't straining Peirce's terminology a bit. Perhaps I was thinking that Peirce speaks in places of degenerate symbols /per se/. For example:

    . . . while the complete object of a symbol, that is to say, its
    meaning, is of the nature of a law, it must denote an
    individual, and must signify a character. A genuine symbol is a
    symbol that has a general meaning. There are two kinds of
    degenerate symbols, the Singular Symbol whose Object is an
    existent individual, and which signifies only such characters as
    that individual may realize; and the Abstract Symbol, whose only
    Object is a character. CP 2.293

I think the meaning here is fairly clear, that there is one kind of genuine symbol (one having a "general meaning"--but that would seem to apply to symbols other than the 'proof' would it not?) and two kinds of degenerate symbols, the Singular (its object being an individual) and the Abstract (its object being a character). But in speaking of" the immediate interpretant of an index," Peirce goes on to say:

    Although the immediate Interpretant of an Index must be an
    Index, yet since its Object may be the Object of an Individual
    [Singular] Symbol, the Index may have such a Symbol for its
    indirect Interpretant. Even a genuine Symbol may be an imperfect
    Interpretant of it. So an icon may have a degenerate Index, or
    an Abstract Symbol, for an indirect Interpretant, and a genuine
    Index or Symbol for an imperfect Interpretant. CP 2.294

I'm having considerable difficulty parsing this second paragraph, especially as to how he's using the terms 'imperfect' and 'indirect' (as opposed to 'intended'?) But it seems to me that it might be important--especially in getting at the concept of "genuine"--to try to grasp Peirce's meaning here.

Best,

Gary R
