Of course. But
all intersections with finite contents
are invisible.
assembling finite sequences holding only
claims which are true.or.not.first.false.
We know that
each claim in the claim.sequence is true
by _looking at the claims_
independently of _looking at the invisible_
_It doesn't matter_
whether any finite.cardinals are invisible.
Each finite cardinal is finite, and
that is enough to start
a finite sequence of claims holding only
claims which are true.or.not.first.false
-- claims about each finite.cardinal, visible or not.
Some claims seem too dull to need verifying.
"Is a finite.cardinal finite?"
Better to ask "Is the Pope Catholic?"
But such obviously.true claims start us off.
Other claims, the more interesting claims,
can be verified as not.first.false
_by looking at the claims_
NOT by looking at finite.cardinals
Look at q in ⟨p p⇒q q⟩
There is no way in which q can be first.false.
It doesn't matter what q means, or what p means.
We can see q is not.first.false in that sequence.
Repeat the pattern ⟨p p⇒q q⟩ and a few others
for a whole finite sequence of claims,
and
that whole finite sequences of claims
holds no first false claim,
and thus holds no false claim.
Which we know by _looking at the claims_

It is a smaller set.

Cardinalities are not useful.And yet, by ignoring them,
you (WM) end up wrong about
⎛ For each k in ℕ
⎝ there is unique k+1 in ℕ\{0}
