² By “small large cardinals" are here meant large cardinals whose existence is compatible
with the axiom of constructibility V = L.Gödel pronounces on one of them.the axiom
stating the existence of an inaccessible cardinal,as follows:
The simplest of thesc "strong axioms of infinity" asscrts the cxistence of inac-
cessible numbers (and of oumbers inaccessiblc in the stronger sensc)>ℵ₀. The
lutter axiom, roughly ans nothing else but that the totality of sets
obtainable by exclusive use of the procedure of formation of sets expressed in the
other axioms forms again a set (and therefore a new basis for further applications
of these processes). ([9], p.182)
The axiom stating the existence of a measurable cardinal, as well as its incompatibility with the
axiom of constructibility, was known to Gödel as he wrote [10].However, Gödel apparently
did not consider this axiom as implied by the coacept of set (see[10], footaote 16).
