Single Idea 7317

[filed under theme 19. Language / A. Nature of Meaning / 8. Synonymy ]

Full Idea

It is easy to see that intersubstitutability salva veritate is not a sufficient condition for synonymy. 'Renate' (with kidney) and 'cordate' (with heart) can be substituted in a purely extensional language, but are plainly not synonymous.

Clarification

'Intersubstitutability salva veritate' meaning swapping without changing the truth value

Gist of Idea

'Renate' and 'cordate' have identical extensions, but are not synonymous

Source

report of Willard Quine (Two Dogmas of Empiricism [1953]) by Alexander Miller - Philosophy of Language 4.2

Book Ref

A Reaction

This seems to be a key example (along with Hesperus, and many others) in mapping out synonymy, meaning, analyticity, sense, reference, extension, intension, and all that stuff.

The 29 ideas from 'Two Dogmas of Empiricism'

Quine's arguments fail because he naively conflates names with descriptions [Fine,K on Quine]
Quine blurs the difference between knowledge of arithmetic and of physics [Jenkins on Quine]
Quine is hopeless circular, deriving ontology from what is literal, and 'literal' from good ontology [Yablo on Quine]
Contrary to some claims, Quine does not deny logical necessity [Quine, by McFetridge]
Quine's attack on the analytic-synthetic distinction undermined necessary truths [Quine, by Shoemaker]
Metaphysical analyticity (and linguistic necessity) are hopeless, but epistemic analyticity is a priori [Boghossian on Quine]
Quine challenges the claim that analytic truths are knowable a priori [Quine, by Kitcher]
Quine's objections to a priori knowledge only work in the domain of science [Horwich on Quine]
Science is empirical, simple and conservative; any belief can hence be abandoned; so no a priori [Quine, by Horwich]
Logic, arithmetic and geometry are revisable and a posteriori; quantum logic could be right [Horwich on Quine]
The second dogma is linking every statement to some determinate observations [Quine, by Yablo]
'Renate' and 'cordate' have identical extensions, but are not synonymous [Quine, by Miller,A]
Quine's attack on analyticity undermined linguistic views of necessity, and analytic views of the a priori [Quine, by Boghossian]
Quine attacks the Fregean idea that we can define analyticity through synonyous substitution [Quine, by Thomasson]
The last two parts of 'Two Dogmas' are much the best [Miller,A on Quine]
Erasing the analytic/synthetic distinction got rid of meanings, and saved philosophy of language [Davidson on Quine]
The analytic needs excessively small units of meaning and empirical confirmation [Quine, by Jenkins]
Analytic statements are either logical truths (all reinterpretations) or they depend on synonymy [Quine]
Aristotelian essence of the object has become the modern essence of meaning [Quine]
Empiricism makes a basic distinction between truths based or not based on facts [Quine]
Once meaning and reference are separated, meaning ceases to seem important [Quine]
Did someone ever actually define 'bachelor' as 'unmarried man'? [Quine]
Definition rests on synonymy, rather than explaining it [Quine]
If we try to define analyticity by synonymy, that leads back to analyticity [Quine]
Statements about the external world face the tribunal of sense experience as a corporate body [Quine]
It is troublesome nonsense to split statements into a linguistic and a factual component [Quine]
Any statement can be held true if we make enough adjustment to the rest of the system [Quine]
If physical objects are a myth, they are useful for making sense of experience [Quine]
Our outer beliefs must match experience, and our inner ones must be simple [Quine]
