All,
I continue with my commentary on CP 3.73, developing the “Othello” example
as a way of illustrating Peirce’s formalism.
Peirce’s 1870 “Logic of Relatives” • Comment 8.2
================================================
https://oeis.org/wiki/Peirce%27s_1870_Logic_Of_Relatives_%E2%80%A2_Part_1#C…
In the development of the story so far, we have a universe
of discourse characterized by the following equations.
1 = B +, C +, D +, E +, I +, J +, O
b = O
m = C +, I +, J +, O
w = B +, D +, E
This much forms a basis for the collection of absolute terms
to be used in the example. Let us now consider how we might
represent an exemplary collection of relative terms.
Consider the genesis of relative terms, for example:
“lover of____”
“betrayer to____of____”
“winner over of____to____from____”
We may regard these fill-in-the-blank forms as being derived by
a kind of rhematic abstraction from the corresponding instances
of absolute terms.
The following examples illustrate the relationships existing among
absolute terms, relative terms, relations, and elementary relations.
• The relative term “lover of____” can be derived from
the absolute term “lover of____Emilia” by removing the
absolute term “Emilia”.
Iago is a lover of Emilia, so the relate-correlate pair I:E
is an element of the dyadic relation associated with the
relative term “lover of____”.
• The relative term “betrayer to____of____” can be derived from
the absolute term “betrayer to Othello of Desdemona” by removing
the absolute terms “Othello” and “Desdemona”.
Iago is a betrayer to Othello of Desdemona, so the elementary relative
term I:O:D is an element of the triadic relation associated with the
relative term “betrayer to____of____”.
• The relative term “winner over of____to____from____” can be derived from
the absolute term “winner over of Othello to Iago from Cassio” by removing
the absolute terms “Othello”, “Iago”, and “Cassio”.
Iago is a winner over of Othello to Iago from Cassio, so the elementary
relative term I:O:I:C is an element of the tetradic relation associated
with the relative term “winner over of____to____from____”.
