Axiom Quote by Georg Cantor
“The old and oft-repeated proposition "Totum est majus sua parte" [the whole is larger than the part] may be applied without proof only in the case of entities that are based upon whole and part; then and only then is it an undeniable consequence of the concepts "totum" and "pars". Unfortunately, however, this "axiom" is used innumerably often without any basis and in neglect of the necessary distinction between "reality" and "quantity", on the one hand, and "number" and "set", on the other, precisely in the sense in which it is generally false.”

The principle that a whole exceeds its parts is only valid when the whole and parts are real, not merely numerical or abstract sets; misapplying it leads to false conclusions about reality versus quantity.
In simple terms: Whole‑part logic works only for concrete entities, not abstract numbers.
Distinguish real wholes from abstract sets.
