|Possibilia, philosophy: possibilia are accepted, possible objects that do not exist (in our world) actually. It is controversial whether one should discuss them at all, since their properties are not so clearly defined that they can always be distinguished from one another, for example, to count them. See also possibilism, actualism, modal realism.|

EMD II 251
Possibilia / Woods: do never exist - their existential predication is always wrong. - Problem: if we accept that the existence-quantifier has no connection to the existence, existence then results only from the signification of constants, not from the quantifier. - It is also no law any more that (x) (x exists) > (Ey) (y = x). - Solution: additional axiom that everything exists at any one time.
