Part 01:
Dialectics and Self-Reflexive
Functions Series.
‘Self-Re-Entry’ of the ‘Metafinite’
Set of All Sets:
A Universal Metaphor for the Dialectics of Nature.
Dear Reader,
G.
Spencer Brown once wrote, long ago, regarding certain expressions of the
super-parsimonious arithmetic-algebra that he had developed, that “...the whole
expression…can…be regarded as re-entering its own inner space…” [G. Spencer Brown, Laws of Form,
George Allen and Unwin, Ltd., 1969, p. 56].
He
also wrote, in the same source: “The question of whether or not functions of
themselves are allowable has been discussed at...length by many authorities
since Principia Mathematica was published. ...if an operation can take its own result as
a base, the function determined by this operation can be its own argument.” [ibid., p. 97,
emphases added by M.D.].
To
whatever degree that Brown’s description of ‘self-re-entry’ may be apt for the
syntactic/computational process that Brown was, in the quote above,
describing, his description is more clearly and more concretely apt for another
process, that he did not there address – namely, for the ‘self-iterating’
process of the finitary [‘metafinite’] ‘“Set of All Sets”’ for a given Domain/universe-of-discourse.
Since that ‘“Set of All Sets”’ is inadequate to itself as soon as it is formed, thereby requiring yet another iteration to attempt its ever-receding, ever-elusive objective, we will denote this ‘ideo-object’ by the symbol St, with t serving as this set-eventity’s ‘self-iterations counter’, its count of the consecutive ‘tries’ at achieving the ‘“Set of All Sets”’.
We will further define the process of this set-eventity by what we will call the ‘«aufheben» evolute product of sets’:
St+1 = St2 = St ´ St = St(St) =
St È 2St, wherein 2St denotes the “power
set”, or “set of all subsets” of the exponentiated set, here St. As an
operator, or operation, upon itself, St(St) or StSt – indeed, as an «aufheben»
self-operation – this product rule defines this ‘“Set of All Sets”’
function as a “Function of Itself”, as a ‘function/argument identical’,
in our sense.
For
every finite value of t, the set St will always lack the containment inside itself of its
very own subsets, hence every such St fails to be its Domain’s ‘“Set of All Sets”’,
and thus definitionally self-requires yet a further ‘self-iteration’, to St+1, and so on.
Now,
note that, for each ‘self-iteration’/stage t, the entire set, St, reappears inside what was its [former] ‘“self”’, St, as its own “improper” subset, and as a new element
within set St+1,
together with all of the other, “proper” subsets of St.
For example, consider the set {x, y, z}. Its set of subsets is of cardinality –
2|{x, y, z}| = 23 = 8, and 2{x, y, z} =
{ {x}, {y}, {z},
{x, y}, {x, z}, {y, z}, {x, y, z}, {_} },
wherein
{_} denotes the “empty set”.
If
we designate {x, y, z} to be S1, then –
S2 = S12 = S1 ´ S1 = S1(S1) =
S1 È 2S1 = {x, y, z} È 2{x, y, z} =
{ x, y, z, {x}, {y},
{z}, {x, y}, {x, z}, {y, z}, {x, y, z}, {_}
}
–
whose cardinality is 11.
For
each stage t, all of St reappears inside what was St, along with the other subsets of St, and thereby creates St+1. Moreover, all
of 2St ‘‘‘re-enters’’’ into the “inner space” of St, thereby changing St, into St+1. Thus St changes itself,
by an ‘ideo-auto-kinesis’ [cf.
Plato; cf. Marx].
Indeed,
St «aufheben»s
itself, in a classic set-theoretical model of ‘the reflexivity paradigm of
dialectics’; and a classic model of, dialectical, ‘self-developing process’.
That
is, the set St determinately
negates itself, as St, by becoming ‘not-St’ in the determinate form of St+1, which is qualitatively unequal
to St.
The
set St also
conserves itself inside the set St+1, by becoming an element
of the set St+1.
The
Set St also
elevates itself, by becoming St+1, a set of cardinality higher than that of St, and also of higher Russellian-Gödelian “logical type”,
and also a set of expanded qualitative, ‘ideo-ontological’
content, containing additional, new “intensions” – new qualities –
as represented by new “extensions”; the new elements that are the ‘extensional-predicate’
subsets of set St.
So, the ‘“Set of All Sets”’ self-operation/self-operator/-self-function thus fulfills all three “moments” of the classic «aufheben», or dialectical, process – determinate negation, conservation, and elevation.
This, ‘“Set of All Sets”’, ‘self-developing [ideational] process’ thus provides an abstract metaphor for each stage, each epoch, of the physical process of ‘“Natural History”’; of the ‘self-meta-evolution’ of our cosmos – in short, of the ‘“Dialectic(s) of Nature”’, each stage ‘modelable’, in the NQ ‘arithmetic for modeling dialectics’, as –
qx ® qx <´> qx = qx2 = qx(qx) =
qx <+> qxx [see ‘dialectogram’ diagram below]
– and it was the metaphor that led to Karl Seldon’s discovery of the ‘self-reflexive functions’ that we have named ‘‘‘The Seldon Functions’’’.
