This is an important point. Clearly "each n in |N has
property P" does not mean "all n in |N have property P"
if we assume that "all n in |N" might not exist.
However from "each n in |N has property P" we can
conclude that no n in |N has property (not P).

Induction works for any property P. E.g Each natural number
is a natural number can be proved by induction.

1 is a natural number.
If n is a natural number n+1 is a natural number
Each n in |N is a natural number.

One gets the same "contradictions" if one uses potential
infinity rather than actual infinity.
