|Mention philosophy: the mention of linguistic objects must be distinguished from their use. This distinction is sometimes difficult when symbols are partly used and partly mentioned within logical formulas. One simple case of a mention of a word or phrase is the quote. See also object language, metalanguage, quote, reference, occurrence, type, token.|

And/characters/mention/use/Tugendhat: "a and b": on the side of the characters we must not expect the expression "p and q", but the expression "that p and that q". This is an analogy, in fact. And they are also in need of completion by a predicate.
But the fact that p and the fact that q are not composed - we need a more general term which somehow contains composition, but goes beyond that.
