Jon, I trust you are eventually going to say something relevant to the content 
of my “Rhematics” post, but in the meantime, here’s the follow-up I promised, 
which specifically relates developments in Peirce’s logic to his categories and 
his Existential Graphs.

 

Peirce was critical of logicians who, like Aristotle, tried to derive logical 
principles from what were really characteristics of language. He was also 
critical of “psychologism” or the attempt to draw logical principles from the 
study of how human minds work. But that doesn't mean he had nothing to say 
about psychology or linguistics; it's just that his remarks about them usually 
occur in a logical (sometimes phenomenological) context.

 

Linguistics, in its analysis of the “parts of speech,” makes a basic 
distinction between nouns and verbs, which is often taken as equivalent to the 
distinction between subject and predicate in logic. Peirce on the other hand 
distinguished between proper nouns (names of individuals) and common nouns 
(general nouns), and he grouped common nouns with verbs and other “words which 
signify.” For instance, CP 4.157 (c. 1897):

[[ The mind, by its instinctive adaptation to the Outer World, represents 
things as being in space, which is its intuitive representation of the 
clustering of reactions. What we call a Thing is a cluster or habit of 
reactions, or, to use a more familiar phrase, is a centre of forces. In 
consequence, of this double mode of association of ideas, when man comes to 
form a language, he makes words of two classes, words which denominate things, 
which things he identifies by the clustering of their reactions, and such words 
are proper names, and words which signify, or mean, qualities, which are 
composite photographs of ideas of feelings, and such words are verbs or 
portions of verbs, such as are adjectives, common nouns, etc.]]

 

In one of his drafts for the Cambridge lectures of 1898, Peirce applied this 
distinction to his early terminology for Existential Graphs. NEM4:338 (R439):

[[Any part of a graph which only needs to have lines of identity attached to it 
to become a complete graph, signifying an assertion, I call a verb. The places 
at which lines of identity can be attached to the verb I call its blank 
subjects. I distinguish verbs according to the numbers of their subject blanks, 
as medads, monads, dyads, triads, etc.]]

 

At this point, the lines of identity are themselves verbs, but their ends are 
proper nouns or demonstrative pronouns. Together with the juxtapositions and 
the “ovals” which later became “cuts,” this gives us three kinds of sign 
corresponding to Peirce's three categories. NEM4:339 (R439): 

[[In the system of graphs may be remarked three kinds of signs of very 
different natures. First, there are the verbs, of endless variety. Among these 
is the line signifying identity. But, second the ends of the line of identity 
(and every verb ought to [be] conceived as having such loose ends) are signs of 
a totally different kind. They are demonstrative pronouns, indicating existing 
objects, not necessarily material things, for they may be events, or even 
qualities, but still objects, merely designated as this or that. In the third 
place the writing of verbs side by side, and the ovals enclosing graphs not 
asserted but subjects of assertion, which last is continually used in 
mathematics and makes one of the great difficulties of mathematics, constitute 
a third, entirely different kind of sign. Signs of the first kind represent 
objects in their firstness, and give the significations of the terms. Signs of 
the second kind represent objects as existing,—and therefore as reacting,—and 
also in their reactions. They contribute the assertive character to the graph. 
Signs of the third kind represent objects as representative, that is in their 
thirdness, and upon them turn all the inferential processes. In point of fact, 
it was considerations about the categories which taught me how to construct the 
system of graphs.]]

 

This, i would submit, represents an early stage in the evolution of the 
trichotomy rheme/dicisign/argument. If so, it shows the continuity between 
Aristotle's rhema, or verb, and Peirce's rheme (or predicate) as represented in 
Existential Graphs.

 

Another observation Peirce made later about linguistics reiterates the idea 
that common or general nouns are more like verbs than they are like proper 
nouns or pronouns. This is an important point for Peirce because it shows that 
logicians err in separating the copula from the predicate in their analysis of 
propositions – and the error seems to arise from a psycholinguistic prejudice 
which prevents them seeing the primacy of verbs over common nouns. EP2:285:

[[It happens to be true that in the overwhelming majority of languages there 
are no general class names and adjectives that are not conceived as parts of 
some verb (even when there really is no such verb) and consequently nothing 
like a copula is required in forming sentences in such languages. The author 
(though with no pretension to being a linguist), has fumbled the grammars of 
many languages in the search for a language constructed at all in the way in 
which the logicians go out of their way to teach that all men think (for even 
if they do so, that has really nothing to do with logic). The only such tongue 
that he has succeeded in finding is the Basque, which seems to have but two or 
three verbs, all the other principal words being conceived as nouns. Every 
language must have proper names; and there is no verb wrapped up in a proper 
name. Therefore, there would seem to be a direct suggestion there of a true 
common noun or adjective. But, notwithstanding that suggestion, almost every 
family of man thinks of general words as parts of verbs. This seems to refute 
the logicians' psychology.]]

 

This explains why Peirce analyzes the proposition into subject and predicate, 
rather than following the traditional three-term analysis into subject, 
predicate and copula. Peirce’s logic has here come a long way from Aristotle's 
distinction between onoma and rhema (see 
http://gnusystems.ca/wp/2017/05/rhematics/), but in my view the developmental 
path has been continuous in all its twists and turns.

I hope to comment more fully, eventually, but the uses to which Susan Awbrey 
and I turned Aristotle's passage from De Interp can be found in our paper from 
1992/1995:
