If you want to say that it exists in actuality then you write something like ∃x (Px ∧ Ax). | |

| Apr 17, 2016 at 18:23 | comment | added | user6917 | Conifold so it seems i can say that something can possibly exist. my follow up comment / question, and please excuse my clumsiness etc., is whether i can say that it is physically possible for something to exist but in reality it actually does exist? i think that's what i mean... | |
