|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/Belief/Belief Attribution/Millikan: E.g. "Ralph believes that every member of our secret club is a spy".
A) Ralph says in his inner language "Every member ..."
B) A form with a gap: "___ is a spy" is filled each time by another member. This is e.g. also possible even if Ralph does not know anything about our club.
Sense: is then the same as in the clearer example: "Of each member believes Ralph ..."
Again, for both readings it applies: a relation between Ralph and a belief type is depicted.
