Induction> holds for all natural numbers, but if they form an actually infinite> thing, then induction does not hold for all of them.Outside of Wolkenmuekenheim, standard induction only holds if the set of naturals IS infinite. For finite sets, one can use non-standard or finite induction, which is not at all the same thing. > Cantor's> argument, however, holds for this infinite thing, because set theory> is defined this way.> > Zermelo made the first mistake, when taking Dedekind's potential> infinity as actual infinity.There is, as yet, no reason to suppose that to be a mistake.And actual infinitenes does allow solutions to Zeno's paradoxes, which in Wolkenmuekenheim still prove motion to be impossible.> Set theorists now make the second> mistake, when claiming that Cantor's diagonalization does not apply to> line after line but to all lines simultaneously.A rule which applies uniformly to all lines WM would not allow to apply to some lines?
