Thus, the notion of "self" is precisely a consequence of the act of
distinction and the basis of identity. As a locus of control and
observation, I (the self) stand apart from the rest of the frame in
which I am embedded. This is the operational definition of "self"
within the design of Smalltalk and in occurrence, within the Smalltalk
image. Thus, all objects that are to be the recipients of messages
should support the behavior of those things that can be uniquely
distinguished, the class of Objects.
Communication is not possible in the absence of distinct and
distinguishable endpoints for that communication. Smalltalk at its core
is not object oriented, but rather, communication oriented.
(Consider that I can substitute a framework of cooperating objects for
a singleton instance if their behaviors are the same. This implies that
it is the patterns of communication that are important in Smalltalk,
not the objects themselves.)
Further, the notion that "names" may be associated with distinguishable
loci of behavior leads to our ability to perceive objects in the first
place. The act of producing a sign to stand as a reference leads to our
perception of an object. Now we are treading into the realm of
semiotics... my studies suggest that objective reality can only be
expressed in a language of description (where by language of
description, I am including all forms and expression of sign production
and signification).
Physics backs this up, when it was discovered that a sensor can only
detect changes in itself. This implies that when I touch a cup, I don't
feel the cup, my finger feels pressure which I perceive as "touching"
the cup. That when I look at a cup, there is no direct connection
between my self and the observed cup, rather that patterns of changes
in my retina which I presume to be the consequence of patterns of
photons that have previously interacted with a cup on their way to my
retina are perceived by me as "seeing" the cup. To reiterate, my only
access to reality, is through a language of description.
My conclusions?
1. selfhood is a consequence of the distinctions that distinguish one
loci of behavior from another.
2. the act of producing a reference to a distinct loci of behavior
leads to the perception of objects.
3. communication is the expression of intents between objects.
4. the object identified by a reference, may itself be a very
structured and behavior full entity capable of many things within the
bounds of the distinction of self. Thus, we use the terms reflection
and introspection to describe communication with self.
5. objective reality is a semiotic process... is a photon event a wave
or a particle? I suppose it depends upon the language of description
one uses in understanding photon events.

PS "The Laws of Form" is a *great* read. Sort of an ontological
approach to mathematics. Things get particularly interesting when
sufficient machinery is built up such that the form may reenter the
form...
