And, if that is the case, integer operations ae not even subsets of real operations -- at least not specificable subsets. << Well, if you take the view that a natural number n *is* the set of sets of cardinality n (Frege) or that it *is* a Zermelo set, or whatever, then you may have trouble identifying the rest of the numeric tower with these particular sets.?

Or Platon, for that matter, who clearly distinguishes between arithmetic numbers (natural) and geometric (real). It is an odd Platonist who thinks that two thingsthat lie under different universals are nontheless the same. That isthe sort of thing that can happen only in the confused world of shadows, not in The Real World. |
