 [F]rom an actualist point of view…there are no possibilities or necessities de re about non-actual individuals. So if I were not an actual individual there would be none about me. The singular propositions that I exist and that I do not exist would not exist to have the logical properties, or enter into the relations with some or all world-stories, by virtue of which my existence or non-existence would be possible or necessary. I therefore say that “\(\Diamond\)(I exist),” “\(\Diamond\)~(I exist),” “\(\Box\)(I exist),” and “\(\Box\)~(I exist)” are all false, and their negations true, at worlds in which I do not exist. Neither my existence nor my non-existence would be possible or necessary if I did not exist. (1981: 29)
