Single Idea 9016

[filed under theme 5. Theory of Logic / F. Referring in Logic / 1. Naming / f. Names eliminated ]

Full Idea

Names are convenient but redundant, because Fa is equivalent to (an x)(a=x,Fx), so a need only occur in the context a=, but this can be rendered as a simple predicate A, so that Fa gives way to (an x)(Ax.Fx).

Gist of Idea

Names are not essential, because naming can be turned into predication

A Reaction

In eliminating names from analysis, Quine takes Russell's strategy a step further. It is probably this which provoked Kripke into going right back to Mill's view of names as basic labels. The name/description boundary is blurred. Mr Gradgrind.


The 6 ideas with the same theme [we can paraphrase names out of sentences entirely]:

The only genuine proper names are 'this' and 'that' [Russell]
We might do without names, by converting them into predicates [Quine, by Kirkham]
Canonical notation needs quantification, variables and predicates, but not names [Quine, by Orenstein]
Quine extended Russell's defining away of definite descriptions, to also define away names [Quine, by Orenstein]
Names are not essential, because naming can be turned into predication [Quine]
Quine's arguments fail because he naively conflates names with descriptions [Fine,K on Quine]
