|Everyone, all: “everyone” and “all” are colloquial forms, which are formalized in logic as quantifiers (universal quantifier). While "all" refers to a collective in general, "everyone" refers to individuals. E.g. everyone can win the lottery, but not all can win the lottery.|

Everyone/All/None/Ontology/Existence/Non-existence/Hintikka: If we allow that the domain of our quantifiers is also extended to non-existent objects, the most urgent question is:
Where are these non-existent objects?
E.g. Everyone's lover - for example, no one's lover.
Both are obviously possible. But unlike Meinong's round square.
E.g. "the envy of all" - e.g. "the one who is envied by everyone".
N.B.: both are incompatible. The former must love the latter, but the latter cannot be loved by the first.
Everyone/all/nobody/Hintikka: it is not a solution here to claim that "everyone" or "nobody" is only possible with existent objects. ((s) That is, we must allow here non-existent or possible objects (possibilia).)
Meinong/Hintikka: gains the power of his arguments from the fact that we have to allow non-existent objects here. (Also> Terence Parsons).
Non-existence/non-existent objects/localization/possible worlds/Hintikka: thesis: any non-existent object is in its own world.
Quantification/Quantifier/Ambiguity/any/HintikkaVsMontague: On the whole, the Montague semantics shows how ambiguity arises through the interplay of quantifiers and intensional expressions. E.g.
(12) A woman loves every man
(13) John is looking for a dog.
HintikkaVsMontague: explains only why certain expressions can be ambiguous, but not which ones they actually are. He generally predicts too many ambiguities. For he is not concerned with the grammatical principles, which often resolve ambiguities with quantifiers.
Domain/Hintikka: the domain determines the logical order.
(14) If he makes an effort, he will be happy.
(15) If everyone makes an effort, he will be happy.
Problem: in English, "if" has precedence with respect to "everyone" so that "everyone" in (15) can not precede the "he" as a pronoun ("pronominalize").
HintikkaVsMontague: so we need additional rules for the order of application of the rules.
