David Nyman gave a much more rigorous definition of primitive
materialism in another thread (he calls it "primordial").
ISTM that what is supposed to be "primordial" about a specific set
of entities and their relations is precisely that they *exclusively*
underlie (or more correctly, comprise) everything that is "really
real". So the hierarchical structure of everything we observe
thereafter - be it physical, chemical, biological, physiological,
etc. - would be deemed to be underpinned, exclusively and
exhaustively, by such a primordial substratum.
I would use the greek term for substratum (hypostase) though, as it is
not a substance in the sense of stuffy thing. With comp we can use the
numbers as (non stuffy) primitive terms, and clearly no physical
objects will ever be said of being "made of numbers" (like stuffy
things are made of other stuffy things). It is really more being
*dreamed by numbers*, with the correct relative statistics. The object
"in your dream" are not stuffy.
In fact I use primitive simply for the assumed object through the TOE
atomic terms.
I don't need a precise definition, so I let open if, in arithmetic,
only 0 is primitive, or if we accept as primitive also s(0), s(s(0)),
etc. Usually I take them all as primitive (but non stuffy) objects.
All what is asked to 0, s(0), s(s(0)), ... is the obedience to logic
and the axioms:
0 ≠ s(x)
s(x) = s(y) -> x = y
x = 0 v Ey(x = s(y))
x+0 = x
x+s(y) = s(x+y)
x*0=0
x*s(y)=(x*y)+x
Does everyone understand them?
