Re: ICE Discussion 38.  http://suo.ieee.org/ontology/msg05328.html

I continue to continue ...

HT: My second question relates to the analogy of particulars and properties to
    particles and waves, which question arises more at this point from a lack
    of a full appreciation of what is meant by particulars and properties.
    But despite my lack of understanding of properties and particulars,
    are you suggesting some sort of coexisting duality of particulars
    and properties -- or are you employing that analogy only to say
    that the implications of Peirce's formalisms are far beyond
    what people may have initially thought?

That's another one of those boldly-go types of abductive leaps that still
makes sense to me when I read it again, but I am moderately cognizant how
much hard trekking there is to do before the series converges on anything
conclusive.  My general sense from reading sundry old school philosophers
is that they always distinguished between "individuals" and "particulars",
taking the first to mean what it says:  atomic, indivisible, unsplittable.
We know what happened to 'that' fond notion -- of finding any such stuffs.
In contrast, a particular is a nominally smallest part in a given setting,
and the sort of thing that might easily be divided in the next discussion.

You can get the flavor of the brands of hairs that the Angelic Doctors
were adept at splitting in the Middle Ages, and Peirce's acquaintance
with them, by scanning the assortment of excerpts I gathered here:

03.  http://suo.ieee.org/ontology/msg04760.html
04.  http://suo.ieee.org/ontology/msg04761.html

I'm not sure that non-angelic non-doctors like me can hope
to match this level of subtlety, but the basic distinction
between individuals and particulars seems clear enough and
actually comes up all the time in everyday applications of
computational logic to practical problems.

That's the individual/particular side of it.

The particular/property side of things is sometimes stated as a question
about "proper names" versus "common nouns", "generals", or "predicates".
This touches once again on the "limits of localization", simple or else.
Is there really a duality here?  And if so, why?  Or is this particular-
to-property dimension more like a homogeneous spectrum of peculiarities?

I don't know any kind of answer here,
but I'm only looking at various ways
that this aspect of reality has been
modeled in the past.

A couple of notes back, for instance, I was refreshing our collective
memories about the ways that these sorts of distinctions are commonly
handled in set theory.  In case you think I made all that up, there's
a collection of more or less relevant excerpts here:

I'll bet we both need to take a break here.
