Hi,
It depends on what you take a syllogism to consist on. The modern
interpretation leaves out the ancient Greek understanding of time. As
you most probably know, CSP wa occupied with the problem of time as
something constantly evolving all his life.
(Thus it is of no use to stic into his early writings on the topic).
This has posed quite a few insurmountable problems to (late) modern
translations of Aristotle, as far as I know the field. Endless
explanations seem to be needed, without ever reaching the very point at
stake.
Is the statement: "Aristotle is sitting" true or false? - Well, of
course it depends...
"Is this a syllogism, or not?" bears the same problems. It depends....

Thanks Ben, Kirsti and list...
So, would you say that CP 5.189 qualifies as syllogism, i.e., is it
"hypothesis" based on what you know of what Peirce said on Aristotle?
Why or why not?
What's the predicate, subject and middle term?
Thanks,
Jerry R

CSP was thoroughly familiar with Aristotle, both his syllogisms and
their context in those times. It may be good to remember that
Aristotle's works, along all others, were translated into Latin by
the time we call the new age.
Translations always involve interpretation. Thus what has passed on
into modern logic & philosophy as 'Aristotelian syllogism' I find
gravely misunderstood. - Basics of Western math had changed, via
Arab influence. The birth of albegra (al-jabr) had taken place.
Ben is putting the discussion into right tracts in introducing
CSP's entries on the topic.

Jon S., Jerry R., Edwina, Jim W., Ben N., list,
"Syllogism" has been used more broadly in the past. I checked the
Century Dictionary's definition of syllogism, of which Peirce was
in
charge.

The discussion of sense 1 is long, and includes not only modus
ponens
but also induction and hypothesis as kinds of syllogism - calling
induction "major indirect probable syllogism" and hypothesis "minor
indirect probable syllogism". However, in later years, Peirce
discusses hypothesis (abductive inference) in terms of plausibility
rather than probability, and even his sense of "probable" in "major
probable syllogism" really refers to what he later calls
verisimilitude, the likeness of the conclusion to the premisses.
Sense 2 of "syllogism" in the Century Dictionary says, "Deductive
or
explicatory reasoning as opposed to induction and hypothesis: a use
of
the term which has been common since Aristotle."
"Statistical syllogism" is discussed in Wikipedia:

Jerry R., List:
I thought that Edwina and I had made it clear by now that CP 5.189
is NOT a syllogism, at least not in the strict technical sense. I
thus take Ben to be using the term colloquially. In fact,
dictionary.com [4] [1] gives three definitions for "syllogism":
* Logic. an argument the conclusion of which is supported by two
premises, of which one (major premise) contains the term (major
term) that is the predicate of the conclusion, and the other (minor
premise) contains the term (minor term) that is the subject of the
conclusion; common to both premises is a term (middle term) that is
excluded from the conclusion. A typical form is “All A is C; all
B
is A; therefore all B is C.”
* deductive reasoning.
* an extremely subtle, sophisticated, or deceptive argument.
I suppose that the third one MIGHT be applicable to CP 5.189, but
in
light of Peirce's well-known concern about the ethics of
terminology, I think that we should steer clear of it in this
context. Again, surprise/suspect are not terms in the syllogism
itself at all; they are what initiates the inquiry (surprise at C)
and what serves as its outcome (suspicion that A explains C) in the
one who is doing the reasoning.
As for your stated desire "to link CP 5.189 with Peirce’s
esoteric
writing in A Neglected Argument"--as I indicated, the syllogism
that
he references in the latter is the one that I outlined previously,
where A and R are the premisses and C is the (deductive) conclusion
that follows from them.
