5.525 It is not correct to render the proposition “(∃x) . fx”—as Russell does—in words “fx is possible”.

Certainty, possibility or impossibility of a state of affairs are not expressed by a proposition but by the fact that an expression is a tautology, a significant proposition or a contradiction.

That precedent to which one would always appeal, must be present in the symbol itself.
