WM call various thingsBy actual infinity I mean what Cantor started but could not stand.
"actually infinite" and "potentially.infinite".
What does he mean by those terms?
NOT "What does Cantor mean? Euclid mean?"
By actual infinity I mean what ZFC claims but cannot maintain.
It is the idea that infinite sets are fixed such that no element can be added or removed.
It is the idea that the natural numbers reach immediately from 0 until ω such that no number can be inserted between ℕ and ω. If every natural nunmber is increased by 1, then the set is shifted from {1, 2, 3, ...} to {2, 3, 4, ..., ω}.
Of course the precondition for this theory is that almost all natural numbers are dark, only a tiny initial segment contains numbers that can be applied individually. The increase of every number mentioned above can only be applied collectively.Which is a statment that you can not maintain, as there is no upper limit to the numbers that can be applied individually.
