7.4 Russell s Machinery generate, create qr code none for .net projects Java Platform Suppose we QR Code JIS X 0510 for .NET regard the present King of France as an individual constant k.9 Suppose, further, that we treat the remainder of (6.

23) as a predicate x exists . This we take to be the universal predicate Ex, true of everything..

Existence We have a l QRCode for .NET ogical truth ( x)E x. By Universal Instantiation, Ek (7.

7) (7.6). is also a l ogical truth. So, if we represent (6.23) as (7.

7), (6.23) turns out to be logically true and its negation turns out to be logically false. This is a formal characterization of the Paradox of Nonbeing.

Russell (1905) rejected this logical representation of (6.23). (6.

23) is not, as he called it, a subject/predicate proposition. If we had a genuine subject, he said, it would be a logical or genuine proper name. In the case of a genuine proper name, we must be directly acquainted with the object named, and so the issue of its existence cannot possibly arise.

10 Both the af rmation and denial of existence in that case are nonsense. Since (6.23) (and its negation) are neither of them nonsense, he concluded, it cannot be that in (6.

23) we are speaking about an object with which we are directly acquainted, and it therefore cannot be that we are predicating anything of such an object. We saw in Section 6.3 that Russell (1905) analyzed the existence claim (6.

23) as a conjunction of the two clauses (6.24) and (6.25).

(6.24) is the existence clause and (6.25) is the uniqueness clause.

Unlike (6.1), there is no third clause, no predication clause, for the obvious reason that Russell did not believe there was any predication in this case. By the same token, Russell proposed the denial of this conjunction, It is not the case that:[there is at least one thing that kings France, and there is at most one thing that kings France].

(7.8) as the representation of (6.22).

The conjunction of the two clauses (6.24) and (6.25) is not a logical truth.

Because the conjunction is not a logical truth, the negation of the conjunction is not a logical falsehood. So Russell claimed to capture informative and nontrivial af rmations and denials of existence. The analysis Russell provided of (6.

23) (and also of (6.22)) assumes two things: rst, that the present King of France is not a subject, and second, that x exists is not a predicate. Russell (1905) never argued that x exists is not a predicate, and it is not an essential component of the theory of descriptions, but an additional assumption.

For the pure theory,. 7.4 Russell s Machinery as we shall call it, that is the theory without this assumption, is suf cient to handle the Paradox with the help of the scope distinction.11 Suppose that x exists were a genuine predicate so that (6.23) receives the usual tripartite analysis: There is at least one thing that presently kings France, and there is at most one thing that presently kings France, and that thing exists.

. (7.9). There are n ow, as usual, two distinct places to insert the not , and so there are two genuine options for interpretation. Using predicate abstract notation, we distinguish the small-scope reading x.E x (k) from the large-scope reading x.

E x (k). (7.11) (7.

10). The large-s .net vs 2010 qr barcode cope reading (7.11) is the de re reading: One and only one thing kings France and that thing does not exist.

On the classical rst-order interpretation, this de re reading is false. For if the thing does not exist, it has no properties. So, in particular, it does not have the nonexistence property.

This is the problematic reading, the one that self-destructs. But we are saved by the de dicto reading, for this makes denials of existence possible. The de dicto reading is the small-scope reading (7.

10). On the classical rst-order interpretation, this de dicto reading is true, for it is simply not the case that one and only one thing kings France and has the existence property. Of course, on the de dicto reading, x exists is a predicate.

It is just not predicated of anything. Let us be clear. The predicate x exists is no different in this regard from any other garden variety predicate, for example, x is bald .

For, on the theory of descriptions, when we say that the present King of France is not bald, and we speak truthfully, the claim must be understood de dicto. x is bald is a predicate though it is certainly not predicated of anything in this case for, as we all know, the present King of France does not exist. We have seen that Russell s reasons for denying that existence is a property of objects are faulty, and so his solution to the Paradox of Nonbeing ultimately depends on the fact that denials of existence are only permitted the small-scope reading.

The scope distinction permits us to identify something as a predicate without its being predicated in that context..
