Again, referring to the sucessor operation s, we haveThe set of natural numbers reaches from zero to omega exclusively: (0, ω). The set {s0, s1, s2, s3, ...} can be mapped on the set {0, 1, 2, 3, ...}. Then all pairs (sn, n) do exist. If however s0 is shifted, i.e., mapped on 1, s1 on 2, and so on, then 0 has no longer a partner and the last sn is mapped on ω.
{1, 2, 3, 4, ...} = {s0, s1, s2, s3, ...} .
If we NOW compare
{s0, s1, s2, s3, ...} (= {1, 2, 3, 4, ...})
with
{ 0, 1, 2, 3, ...} ,
does ist STILL make sense to claim "everybody can see that they are not equal in size"?
