 So while the numbers regress and the events regress are structurally analogous, we might find the principles that yield the regress objectionable in one case but not the other, because while each regress entails that there are infinitely many things of kind \(K\), whether that is a vice may depend on what kind \(K\) is, and whether we have independent reason to think that the domain of \(K\)s is a finite one. Yielding infinitely many things of kind \(K\) might be a local vice when the kind in question is events separated in time, but not when the kind in question is natural numbers structured by the successor relation.
