All,
Sign relations are special cases of triadic relations in much
the same way binary operations in mathematics are special cases
of triadic relations. It amounts to a minor complication that
we participate in sign relations whenever we talk or think about
anything else but it still makes sense to try and tease the separate
issues apart as much as we possibly can.
As far as relations in general go, relative terms are often
expressed by means of slotted frames like “brother of __”,
“divisor of __”, and “sum of __ and __”. Peirce referred to
these kinds of incomplete expressions as “rhemes” or “rhemata”
and Frege used the adjective “ungesättigt” or “unsaturated” to
convey more or less the same idea.
Switching the focus to sign relations, it's fair to ask what kinds
of objects might be denoted by pieces of code like “brother of __”,
“divisor of __”, and “sum of __ and __”. And while we're at it, what
is this thing called “denotation”, anyway?
