List – I am concerned about some of the analyses written recently. 
 
JAS wrote:
 
1] “As I have pointed out previously, Peirce offers a clue about this already 
in 1903--the sign is the first correlate of the genuine triadic relation of 
representing/mediating, and thus the simplest; the object is its second 
correlate, and thus of middling complexity; and the interpretant is its third 
correlate, and thus the most complex (CP 2.235-42, EP 2:290). 
 
This is a half-quotation and misleading. Peirce did not say that the sign, as 
the first correlate, is the simplest. One has to define what is meant by 
‘simplest’ – and it is not, in my view, referring to the category of Firstness, 
but to the relationship that correlate has with the other two correlates.   As 
the first correlate, it is the first in the ordinal process of semiosis and 
Peirce actually writes that it is a ‘mere possibility if any one of the three 
is of that nature and not being a law unless all three are of that nature”. 
2.235 [my emphasis]. That is, this correlate is the least flexible of the triad.
 
And the second correlate “is that one of the three which is regarded as of 
middling complexity, so that if any two are of the same nature, as to being 
either mere possibilities, actual existences or laws, then the Second Correlate 
is of that same nature, while if the three are all of different natures, the 
Second Correlate is an actual existence.” 2.237. [my emphasis]. This, to me, 
suggests that this correlate has more flexibility and openness. 
 
And he did not say that the third correlate is the ‘most complex’ which does 
not suggest that it is in the mode of Thirdness, but it is “of the most complex 
nature, being a law if any one of the three is a law and not being a mere 
possibility unless all three are of that nature’. 2.236.[my emphasis].And 
again, this to me, suggests that this correlate is the most open in its 
organization of meaning.
 
I understand the terms of ‘simple, middling complex, and most complex,’ to 
refer not to the categories but to their relationship with the other 
correlates. . . 
 
The way JAS has interpreted Peirce, it’s setting up the Sign as in a 
categorical mode of 1ns, the object in 2ns, and the Interpretant in 3ns. Peirce 
did not write this…and if you see the ten classes, such a view is incorrect and 
even impossible.  
 
2] JAS wrote: He eventually provides the definitive answer in his Logic 
Notebook, employing the terminology of phaneroscopic analysis. "A sign is a 
Priman which is Secundan to an Object and is Tertian in determining an 
Interpretant into Secundanity to that Object. It has two Objects, the 
immediate, to which it is degenerately Secundan, the dynamic, to which it is 
genuinely Secundan. It has three Interpretants, the immediate, to which it is 
primarily Tertian, the dynamic, to which it is secundally Tertian, the 
rational, to which it is genuinely Tertian" (R 339:247r 
<https://iiif.lib.harvard.edu/manifests/view/drs:15255301$467i>, 1905 Jul 7). 
 
Again, I consider this an incorrect interpretation. The terms of primam, 
secundan and tertian do not, as I understand them, refer to the categorical 
modes of Firstness, Secondness and Thirdness –  but instead, to the order of 
semiosic processing. This order can be seen clearly in Peirce’s well-known 
example in 8,314, about the weather. 
 
3] JAS writes: 
I trust that the equivalence of the "rational" and "normal" interpretants in 
these quotations with the final interpretant is not controversial, nor the 
alignment of "primarily Tertian" and "secundally Tertian" with doubly 
degenerate (1ns of 3ns) and degenerate (2ns of 3ns), respectively. 
 
Again – I consider that these terms refer to the ordinal process of semiosis, 
not to the categories – and disagree with the interpretation that the 
Interpretants are in various modes of Thirdness. Again, just take a look at the 
ten classes of signs – and you’ll see that there is only ONE class where the 
Interpretant is in a mode of Thirdness!!. And a bit of thought would lead one, 
surely, to wonder why the interpretants would be focused around common ‘habit 
generation’, which is the function of Thirdness – and ignore the immediate 
indexical reality of the world. 
 
I’ll also add that I disagree with JAS that “semiosis always already is general 
and continuous’ for this privileges Thirdness and ignores the realities of both 
Firstness [chance, freedom] and Secondness [ individual deviations and 
realities]. Certainly, I consider that semiosis is continuous in the universe – 
but consider that it includes all three categories. 
 
I am aware that my views will not affect JAS’s analysis – but I do feel that 
the List should realize that there are other interpretations of these areas in 
Peirce!
