18776 | Contextual definitions eliminate descriptions from contexts [Linsky,B] |
Full Idea: A 'contextual' definition shows how to eliminate a description from a context. | |
From: Bernard Linsky (Quantification and Descriptions [2014], 2) | |
A reaction: I'm trying to think of an example, but what I come up with are better described as 'paraphrases' than as 'definitions'. |
10845 | To be true a sentence must express a proposition, and not be ambiguous or vague or just expressive [Lewis] |
Full Idea: Sentences or assertions can be derivately called true, if they succeed in expressing determinate propositions. A sentence can be ambiguous or vague or paradoxical or ungrounded or not declarative or a mere expression of feeling. | |
From: David Lewis (Forget the 'correspondence theory of truth' [2001], p.276) | |
A reaction: Lewis has, of course, a peculiar notion of what a proposition is - it's a set of possible worlds. I, with my more psychological approach, take a proposition to be a particular sort of brain event. |
10847 | Truthmakers are about existential grounding, not about truth [Lewis] |
Full Idea: Instances of the truthmaker principle are equivalent to biconditionals not about truth but about the existential grounding of all manner of other things; the flying pigs, or what-have-you. | |
From: David Lewis (Forget the 'correspondence theory of truth' [2001]) | |
A reaction: The question then is what the difference is between 'existential grounding' and 'truth'. There wouldn't seem to be any difference at all if the proposition in question was a simple existential claim. |
10846 | Truthmaker is correspondence, but without the requirement to be one-to-one [Lewis] |
Full Idea: The truthmaker principle seems to be a version of the correspondence theory of truth, but differs mostly in denying that the correspondence of truths to facts must be one-to-one. | |
From: David Lewis (Forget the 'correspondence theory of truth' [2001], p.277) | |
A reaction: In other words, several different sentences might have exactly the same truthmaker. |
18774 | Definite descriptions, unlike proper names, have a logical structure [Linsky,B] |
Full Idea: Definite descriptions seem to have a logical structure in a way that proper names do not. | |
From: Bernard Linsky (Quantification and Descriptions [2014], 1.1.1) | |
A reaction: Thus descriptions have implications which plain names do not. |
21982 | I only wish I had such eyes as to see Nobody! It's as much as I can do to see real people. [Carroll,L] |
Full Idea: "I see nobody on the road," said Alice. - "I only wish I had such eyes," the King remarked. ..."To be able to see Nobody! ...Why, it's as much as I can do to see real people." | |
From: Lewis Carroll (C.Dodgson) (Through the Looking Glass [1886], p.189), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.7 | |
A reaction: [Moore quotes this, inevitably, in a chapter on Hegel] This may be a better candidate for the birth of philosophy of language than Frege's Groundwork. |
