Of course you would mean "finite ordinals as
a brief summary model of discernibles the members"
of "the closure of all relations that make things
numbers, all those sets, too, all the related things",
"the" "numbers".

One might assume "the finite, whole, natural, non-negative,
counting integers, including zero, have a model of a
representation of each their indidividuals, as a
set of finite ordinals, suitable as a value to indicate
a member".

Then, where it's so that extensionally they "are", ...,
"the natural integers", is when for all purposes they
aren't not. It's not always so, yet, for a particular
broad class of theorems call "inductive counting arguments"
it's quite so.

It's sort of like that "TND" is sort of a class,
not necessarily a property of all propositions,
that it's particularly tractable when they are,
they aren't always.

It's like, if Chrysippus had been around so
that Plotinus and the Neo-Platonist Stoics
hadn't made it so Plotinus' weasel-words about
all the Aristotlean didn't result that Chrysippus'
moods would better reflect the modality (moo-dality)
thus that Russell et alia wouldn't be able to say
that "well Plotinus is classical so material implication
is classical" when it's so instead that the classical
already at least _solved_ that away in Chrysippus modal logic,
then maybe it wouldn't all along been "classical QUASI-modal logic",
as ruined the intuition of a century of scholastics.
