The answer to this is that we reject that “some eclipsed is not a moon” and similar statements are false if the subject is taken according to the essentialist reading. This is because, in this case, its meaning is some of what would be eclipsed, were it to come to exist, would not be a moon, insofar as it had come to exist. [The claim this is false] is to be rejected; the most that can be said in this matter is that every eclipsed that has come to exist is a moon, but from this is does not follow that it is true that everything that is eclipsed, were it to come to exist, would be a moon insofar as it comes to exist. This is because [the proposition with an essentialist subject] deals with actual, possible and impossible items [that come under the subject term]. Were we to stipulate the possibility [of these items] along with [the other stipulations], their status would be that of externally existent things. So the eclipsed-which-is-not-a-moon, even though it is impossible, is among those individuals which would be eclipsed, were they to come to exist, even though it is not necessary that any would be a moon if they came to exist.
