Dear Jerry, List
This may help to the development of Jerry Rhee’s question.
Peirce, at least up to 1883, is satisfied with the sample of hypothesis
(later abduction) given in “The new list of categories” (1867):
“In an argument, the premises form a representation of the conclusion,
because they _indicate_ the interpretant of the argument, or
representation representing it to represent its object. The premises may
afford a likeness (an icon), index or symbol of the conclusion. In
deductive argument, the conclusion is represented by the premises as by
a general sign under which it is contained. In _hypotheses_, something
/like/ the conclusion is proved, that is, the premises form _a likeness_
(an icon) of the conclusion. Take, for example, the following argument: -
/M/ is, for instance, /P’/, /P”/, /P”’/, and /P^iv /;
/S/ is /P’/, /P”/, /P”’/, and /P^iv /:
../S/ is /M/.
Here the first premise amounts to this, that “/P’/, /P”/, /P”’/, y /P^iv
/” is _a likeness_ (an icon) of /M/, and thus the premises are or
represent _a likeness_ (an icon) of the conclusion.
That it is different with _induction_ another example will show.
/S’/, /S”/, /S”’/, and /S^iv / are taken as samples of the collection /M/;
/S’/, /S”/, /S”’/, and /S^iv / are /P/:
..All /M/ is /P/.
Hence the first premise amounts to saying that /S’/, /S”/, /S”’/, y
/S^iv / is an _index_ of /M/. Hence the premises are an _index_ of the
conclusion.” (/W2/: 58)
-Underlines and brackets are mine (Miguel) -
The hypothesis sample could, then, be re-written:
/M/ is /something like/ /P’/, /P”/, /P”’/, and /P^iv /;
/S/ is /P’/, /P”/, /P”’/, and /P^iv /:
../S/ is /M/.
