Observation: If "definable numbers" is replaced by "finitely many numbers" WM's nonsense actually seems to make some sense:

Now this one:
ℕ is all natural numbers.
Not more and not less.
*sigh*
| ℕ is THE SET OF all natural numbers
especially in the context of set theory. :-)
for each j ∈ ℕ
there are ℵ₀.many followers in ℕ
Indeed!
Is ℕ more than every j ∈ ℕ?
Huh?!
What is it more?
More nonsense?
| Is ℕ larger than every j in ℕ?
Yeah, if IN is defined due to von Neumann, we actually have that An e IN: n c IN. If we define x < y :<-> x c n and ω := IN, we get the well known theorem: An e IN: n < ω.
