No, it doesn't. At best it would seem to show, correctly,

that no proposition can quantify over EVERYthing.

Quantifying is, in any sense, something that it would

be hard to allege that any SINGLE proposition does AT

ALL. The way quantification WORKS in contexts where it

is REASONABLY defined entails that WHOLE REALMS

of propositions, ALL, JOINTLY, quantify over some other

realm in THE SAME manner. To speak of any one of the

individual propositions quantifying over anything at all is

basically ungrammatical.

Let me briefly expound the paradox.

Nobody here is stopping you, but the point is, your

attempt fails.

Consider

(1) all propositions not about themselves are propositions

If (1) quantifies over (1),

Well, whether 1 quantifies over 1 (or not) DEPENDS on whether

1 is (or is not) a proposition. IF IT IS, then OF COURSE it

quantifies

over itself. It is also clearly tautologous. It is NOT, however,

clearly

ABOUT itself. Nor is it clearly NOT about itself, for that matter.

That, however, simply has nothing to do with whether it is a

proposition.

then (1) is about (1) iff (1) is not about (1).

That simply does not follow.

You have 3 SEPARATE questions to answer about 1.

1. Is 1 a proposition?

2. Does 1 quantify over itself?

3. Is 1 about itself?

There is no paradox unless ALL 8

of the universes this puts us into are paradoxical.
