New Actualism and Iterated Modalities

To see that iterated modalities pose no problem for new actualism, recall first that the sentence

(7)	The pope (i.e., Joseph Ratzinger) could have had a son who could have become a priest.

can be represented as:

(8)	◇∃x(Sxp &◇Px)

But (8) has straightforward actualist truth conditions requiring no possibilia: The thing x which might have been both the pope's son and possibly a priest is a contingently nonconcrete object that at some other world is the pope's son and at yet another world is a priest.
